Re: Help ! No syslog anymore

[Bhasker C V]

Michael,
You are a star.
I dont know what I did before but I re-installed rsyslog and changed the
PrivateTmp to no
It works now.
I can see /tmp/server.log is now pushing syslog contents
Thank you very much.

Re: Help ! No syslog anymore

I forgot to answer the question on why I am doing this
I am experimenting on a no-log system where there is no writes what-so-ever
to /var/log (except for mails) or systemd journal (currently kept volatile)
/tmp/ is tmpfs mounted
Attached is the rsyslog config as-it-is being used now.

rsyslog.conf
Description: Binary data

Re: Help ! No syslog anymore

[Bhasker C V]

Hi,
I have tried removing PrivateTmp=no in the rsyslog service file and it
still doesnt work
I  have removed the service file which I had created too.
I found that when I run the daemon manually, it works well. Hence I have
disabled rsyslog and I have put the daemon startup in my rc-local

But yes, removing PrivateTmp doesnt help.
I am happy to troubleshoot this if anyone wants me to be a QA for this.

Re: Help ! No syslog anymore

[Bhasker C V]

Thanks very  much.
Adding bind path did not help. I found that if I run rsyslog from
command-line as unconfined_t, it works well. It is just the extra systemd
locks which fail
I have since written a simple systemd unit file to make rsyslog work and it
has started working

# /etc/systemd/system/user-rsyslog.service
[Unit]
Description=Simple Rsyslog service
After=network.target auditd.service

[Service]
Type=simple
ExecStart=pkill -9 -f rsyslogd;/usr/sbin/rsyslogd -n -iNONE

[Install]
WantedBy=multi-user.target

Help ! No syslog anymore

[Bhasker C V]

Hi,

 I moved my syslog to a different location  '/tmp/server.log'
This was working all fine until I moved to selinux in enforcing mode.

I have the file context as system_u:object_r:syslogd_runtime_t:s0
now, the file is empty
Strangely ...
lsof shows rsyslog is using this file

rsyslogd 25561 root4r   CHR1,9  0t0 18
/dev/urandom
rsyslogd 25561 root5r   REG   0,440 4026532059
/proc/kmsg
rsyslogd 25561 root6u  unix 0xc5984619  0t0 136109
type=DGRAM (CONNECTED)
rsyslogd 25561 root7w   REG   0,35 8952   4873
/tmp/server.log
rsyslogd 25561 root8w   REG   0,35 8952   4873
/tmp/server.log
rsyslogd 25561 root9w   REG   0,35 8952   4873
/tmp/server.log

But, the file says it is not being used by rsyslog

 $ sudo lsof /tmp/server.log
COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
tail24848  bcv3r   REG   0,35   39   37 /tmp/server.log

There are also no messages in the kernel which I can use to audit any
access/deny issues for selinux.
I have tried putting selinux in permissive state and that too did not help
Please could someone help ? Or if there is a procedure to move syslog file
/var/log/syslog to a different location, I am happy to follow ...

Re: Help ! libvirt

[Bhasker C V]

I finally fixed it.
The issue seems to be with the tpm-tis/cpu backend  (wonder why it shows up
with a different error)
For the sake of community, I am attaching the new xml file so that you can
do forensics on what changed
(I prettymuch did a virt-install --import --print-xml to redo the config
keeping everything intact)

I found another issue
If I switch the suspend-to-disk enabled="yes"
I strangely get an error
error: operation failed: Unable to find any firmware to satisfy 'efi'

I presume the errors being spit out are not accurate description of
failures anymore with libvirt and for the life of mine I could not find why
the other xml file doesnt work and why this does.
Happy libvirt-ing

Help ! libvirt

[Bhasker C V]

I am getting an error with libivrt when I create a VM

```
 $ sudo virsh create ./win11.xml
error: Failed to create domain from ./win11.xml
error: internal error: mishandled storage format 'none'

```

This is after I have done a dist-upgrade (was working fine before)
debian trixie.

error message says
qemuBlockStorageSourceGetBlockdevFormatProps:1227 : internal error:
mishandled storage format 'none'

Security question about daemon-init

[Bhasker C V]

Apologies in advance for cross-group posting.

I have enabled selinux  and after carefully allowing certain permissions, I
have put my system in enforcing mode

I do see a suspicious line like this


[  115.089395] audit: type=1400 audit(1693329979.841:11): avc:  denied  {
getattr } for  pid=3104 comm="daemon-init" path="/home/bcv/.thunderbird"
dev="dm-5" ino=257 scontext=system_u:system_r:virtd_t:s0
tcontext=system_u:object_r:thunderbird_home_t:s0 tclass=lnk_file
permissive=0

I am not sure why on earth would daemon-init try to read .thunderbird
directory under my homedir .

Has anyone faced this problem?

What is this daemon-init program and why does it want access to my home
thunderbird directory ?

Re: mailx and selinux not co-operating

[Bhasker C V]

For future reference

There is another package mailutils which also provides /usr/bin/mail.
This is working fine with selinux in enforcing mode.
This is a good alternative

Re: mailx and selinux not co-operating

[Bhasker C V]

Thanks Nicholas
However, it doesnt  to my knowledge looks like an issue with mailx or
sendmail (I use exim4).
The reason i derive at at is because the whole thing works the moment i
disable selinux.

What i wonder is why selinux is not complaining about the failure ? No logs
whatsoever ...

mailx and selinux not co-operating

[Bhasker C V]

Finally i switched on the enforcing mode on my linux system
Pretty much everything is working except

```
$ echo hello | mail -s test x...@yyy.xyz
2023-08-20 14:39:30 1qXieQ-000Bpa-1P 1qXieQ-000Bpa-1P no recipients found
in headers
Can't send mail: sendmail process failed with error code 1
```
however the same works fine when I put selinux in permissive state (no
warnings shown in audit/dmesg)

A quick ltrace says
```
 1qXia0-000BPb-0a Failed to create spool file
/var/spool/exim4//input//1qXia0-000BPb-0a-D: Permission denied
```

However there are no avc: messages for me to allow this through in my
selinux module
I even tried

```
allow unconfined_t exim_spool_t:file { open read write create };
allow unconfined_t exim_spool_t:dir { open read write };
```

since /var/spool/exim4/input has exim_spool_dir set in it

I cant fine any booleans either ..

Please could someone tell me how to get this to work ? has anyone got mailx
working with selinux on their system ?

Re: recover old files after key deprecations in openssl3

Thanks Dan, i did that anyway. I compiled 1.1 and decrypted and
re-encrypted them. My data is back.
I didnt know that there is such backward compatibility issues with 3.x

recover old files after key deprecations in openssl3

[Bhasker C V]

Hi,


 Could someone help me please on how do I go about migrating data of 
mine from old SSL encryption


 For instance


OPENSSL 1.1 (on a old system)

$ echo hai | openssl bf-cbc -md md5 > hello.txt

and then in

OPENSSL 3

$ cat hello.txt  | openssl bf-cbc  -md md5 -d -provider legacy
enter BF-CBC decryption password:
*** WARNING : deprecated key derivation used.
Using -iter or -pbkdf2 would be better.
EVP_BytesToKey failed
40D7C740377F:error:0308010C:digital envelope 
routines:inner_evp_generic_fetch:unsupported:../crypto/evp/evp_fetch.c:373:Global 
default library context, Algorithm (MD5 : 100), Properties ()
40D7C740377F:error:0386:digital envelope 
routines:evp_md_init_internal:initialization 
error:../crypto/evp/digest.c:252:



Is there anything else missing other than -provider legacy for 
decrypting such files ? I am guessing the MD5 is not compatible with 
legacy provider.


I have tried fips, base, legacy

DNS resolver issue

[Bhasker C V]

Hi all,

 Please could someone help me with  what I am doing wrong ?

I am running  example.local domain on my interface(192.168.2.1)  (bind9)
The domain is resolving fine. However I want to use 1.1.1.1 public DNS
server for looking up other domains (external domains)
Hence I have put both servers in /etc/resolv.conf

``` nameserver 1.1.1.1
nameserver 192.168.2.1
search example.local```

However dig stops after it gets a null result from 1.1.1.1 and does not
proceed to 192.168.2.1 to ask for server.example.local
i.e
```
$ dig server.example.local

; <<>> DiG 9.17.21-1-Debian <<>> server.example.local
;; global options: +cmd
;; Got answer:
;; WARNING: .local is reserved for Multicast DNS
;; You are currently testing what happens when an mDNS query is leaked to

;; MSG SIZE  rcvd: 124

```

WHEREAS if I switch the resolv.conf to have my DNS first (and then 1.1.1.1)
, the local resolution works whereas external resolution does not work
```
nameserver 192.168.2.1
nameserver 1.1.1.1
search example.local```

$ dig +short server.example.local
192.168.2.2



Now, isnt the lookup supposed to fall back to next server if first one
doesnt have an answer ? How does multiple DNS servers entry work in
resolv.conf ?
My nsswitch.conf is :

hosts:  files dns [NOTFOUND=merge]


Please help.

Networkmanager hell !

[Bhasker C V]

Hi,

 I recently compiled the wl driver for my BCM4331 and the driver loads 
fine.


 Networkmanager lists wifi network but does not connect ! (nm-applet 
shows a single dot and then keeps revolving around until it fails)


However,

 1. I stop Networkmanager and wpa_supplicant

 2. I generate a simple config using wpa_passphrase

 3. connect via wpa_supplicant -Dwext -cconfig -iwlp4s0

  and it works !

I have tried to google through as much as possible to understand why 
wpa_supplicant does not connect under NetworkManager but works fine when 
run stand-alone !


I would appreciate if someone can tell me what is happening. I can send 
the logs if needed.


Is there a way to debug networkmanager ?

All that I can do by running network-manager from commandline in 
foreground is


wpa_supplicant[28827]: wlp4s0: CTRL-EVENT-SSID-TEMP-DISABLED id=0 
ssid="myssid" auth_failures=2 duration=20 reason=CONN_FAILED


Before someone says that this is password issue, i am pretty sure I am 
typing the password correct and have confirmed it by looking into the 
system-connections folder for that connection.


If I use another USB adapter, networkmanager is able to connecto the 
same wifi.


Please ! I am going mad here ! There is no good info anywhere to debug 
wpa_supplicant working under networkmanager (OR) to dump the config 
generated by networkmanager

Allow only selected USB

[Bhasker C V]

Hi all,

I know it is very useful that linux auto-detects a USB device when 
plugged in. However I am trying to build a server which employs deny 
first rule. That is, I don't want linux kernel to detect any USB device 
even if plugged in except those listed with a Vendor/device ID in a file 
(perhaps stored somewhere securely in the server).


Is this possible ? I tried to skim though internet but could not find 
any useful information except some pages reporting how to disable USB 
storage.


Please could someone help me with some pointers ?

Cups preserve job files

[Bhasker C V]

Hi,

 I am on bulls-eye.

 For the purpose of history I want to preserve the job files (not just
the job list)

 I understand that cups has

  PreserveJobFiles  which tells the job to be preserved.

 I cannot find out where the job files are preserved and also cannot
find out an option to control how long the job files are preserved.

 I want to also change the location of the jobfiles being preserved to
an encrypted path.

 Could someone help me with these please ?

thanks

Bluetooth audio periodic disconnect

[Bhasker C V]

Hi all,
  I am on bullseye.
  I have tried and tested this with many headphones

 When on bluetooth the audio gets periodically disconnected and re-connects
to audio after 5 seconds.
 During the time the bluetooth per-say does not get disconnected but just
the audio stops and then starts again in 5 seconds.
 I have already set laptop-mode tools to blacklist usb power management for
my usb adapter.
 There are no issues with bluetooth lag or connection issues. My headphones
connect fine and work fine except for the intermittent disconnects.

 Please could someone help me fix this ?

Security issue ... please could someone help !!!

[Bhasker C V]

Hi,

 Attached is something I found. I see that cryptsetup --key-file
arguement uses only first 32 bytes of the file and anything beyond is
unused. 

I am on debian bullseye

$ cryptsetup --version
cryptsetup 2.3.0
$

Following is my test

$ cat b
#!/bin/bash

#create  a file
dd if=/dev/zero of=./A bs=1 count=1 seek=50M
#create a key
dd if=/dev/urandom of=./key1 bs=1024 count=1 
#create a plain dm-mapped crypt device with that key
cryptsetup create dev1 ./A --key-file ./key1
mkfs.ext4 /dev/mapper/dev1

cryptsetup remove dev1

#Now that all is cleaned lets play with key again

dd if=./key1 of=./key2 bs=512 count=1   #We create a key half the size
of the original key

cryptsetup create dev1 ./A --key-file ./key2

#check if the filesystem is the same ...  if it is then there is a trouble
file -sL /dev/mapper/dev1
$ sudo ./b
1+0 records in
1+0 records out

$

I kept digging down and saw that anything below 32 bytes is not accepted
(by cryptsetup --key-file option) but anything above 32 bytes is
discarded. Does this mean that cryptsetup plain with --key-file uses
only 32 bytes ? Am I doing anything wrong ? I dont want to use
passphrases and would like to get the keys from randomly generated key
file. If only 32 bytes are used, it is (in my opinion) not so much
secure isnt it  ?

xscreensaver does not lock

[Bhasker C V]

Hi,

 I am at a loss to understand why xscreensaver does not work anymore.

 I am on bullseye. I have two systems the other, however, works fine and
locks.

 xscreensaver does not seem to have any debug facility from what I could
read from the man pages.

 My config is attached. xscreensaver never gets activated although the
daemon is running in the background.

 xscreensaver binary itself is installed as setuid-root.

 Please help ! thanks.

PS: I tried to compile from source so that I can introduce debugs. This
went in vain since there are too many dependencies and I was not
successful in compiling.

Re: cracking sound from left channel

Dear Dan,

I came across a website which said to use the index parameter
Hence I create this in /etc/modprobe.d/snd_amd.conf
with content

options snd_hda_intel power_save=1 index=1,0

The sound is infintely better now and there is no more fluttering
sound and no leaking of right channel into left which had caused the
distructive interference like audio.
Thanks

Re: cracking sound from left channel

[Bhasker C V]

Thanks Dan,
The audio cracking comes up only after a suspend resume or reboot when
done on its own
If I boot into windows, reboot the system (without switchoff) into
linux, the sound is fine. The next time i reboot into linux the issue
comes back.

The sound is as if the speaker paper of an old speaker is torn. The
fluttering sound when there is high bass on the headphones. The sound is
clear
and fine when on windows and when on linux when immediately booted after
windows.

This to my limited knowledge feels like windows writes something to the
config registers or downloads a firmware which makes sound card work
fine but then when cold booted into linux, linux is missing to do
something. ... may be I am wrong.

cracking sound from left channel

[Bhasker C V]

Hi,

 I am on debian bullseye x86_64 (K5.6.0-rc6).

 03:00.5 Multimedia controller: Advanced Micro Devices, Inc. [AMD]
Raven/Raven2/FireFlight/Renoir Audio Processor

I have windows booting on another partition. After windows boots, and
then I reboot into linux, the sound is fine. All clear on both channels.
But once i reboot into linux or suspend/resume, I get a cracking sound
along with audio on the left channel. I am not sure how to troubleshoot.
Is this a known issue ? Please could someone point me in the right
direction on fix or how to troubleshoot ?

Re: Applet to find internet status

But we could use an external IP to communicate ... like 1.1.1.1 or
curl to some known website to confirm that internet works (which will
include the system proxy settings).
But you are right. It would be easier to write one and taylor it to
the network needs of that person.

I even tried to edit  ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml
and I have set the value of raise to

Even that did not make any difference (given the max delay is  2000)

AND THEN offer the various time delay option check boxes, etc, such as

XFCE and auto-raise too fast

[Bhasker C V]

Hi,

 Attached is screenshot of the settings I have used.

 The auto-raise interval on the other hand is not honouring the 
setting. No matter what the raise interval is configued as, the windows 
auto-raise in 0.5 seconds. Please could someone tell me if I am missing 
something ?

Help with udev trigger

[Bhasker C V]

Hi,

 Version: buster
 I do a manual cryptsetup to create my home directory after system boots up
 I want to run fsck every time the device node is created from luks

 I added this udev rule

ACTION="change",DEVTYPE="disk",ID_FS_UUID="cf1b64cf-7a62-4a43-ad44-6c68f2bbdec5"
RUN+="/bin/btrfsck /dev/mapper/home"

But this rule is not getting triggered. Could someone help please to
point out what mistake I am doing ?

The following is what I get when the device is added from which I
deduced the above trigger line

Weird font dots in terminal

[Bhasker C V]

Hi,

 I am using debian buster.

 I have been using rxvt-unicode with Gohu font happily until the latest update.
 The terminal window now shows extra pixels around the characters.
 Attached is screenshot.
 I have run fc-cache both as root and also as user and re-started the
laptop too.

Attached is the screenshot. This was all clean just a few days ago

My rxvt command is

urxvtc -xrm 'XTerm*selectToClipboard:true' -bc -cr GREEN -vb -fn
'xft:GohuFont:pixelsize=14' -sl 5 -fg \#FF7E00 -bg BLACK

and I have these in

hddtemp for Seagate backup plus

[Bhasker C V]

Hi,

  I have Seagate backup plus external USB 3.0 HDD and by default hdd
temp does not show the hdd temperature


$ sudo hddtemp /dev/sda
/dev/sda: Seagate BUP BK: S.M.A.R.T. not available


However if I use this:
$ sudo hddtemp SATA:/dev/sda
/dev/sda: : 42°C

I tried to read through the manual to find out how to specify the type
in the hddtemp.db but there doesnot seem to be any way I could find.
I added this line in vain.
"Seagate BUP BK"190 C "Seagate BUP BK"

Is there a way to monitor hddtemp on this hdd ? If there is any other
alternative to hddtemp .. please do tell me

thanks

hdparm reporting a different serial number

[Bhasker C V]

Hi all,
 I have a seagate backup plus 5TB.
 When I plug-in the hdd, I see the serial number (as printed in the
back of the HDD) in dmesg.

usb 2-1.1: SerialNumber: 
[5.244161] usbcore: registered new interface driver usb-storage
[5.245790] scsi host6: uas
[5.246015] usbcore: registered new interface driver uas

[5.285790] sd 6:0:0:0: [sda] Mode Sense: 53 00 00 08
This serial number is correct ! (Actuial serial number is obfuscated)

Whereas, when I do a hdparm or smartctl -i , I get a different serial number.

ATA device, with non-removable media
Model Number:   ST5000LM000-2AN170
Serial Number:  YYY
Firmware Revision:  0001
Transport:  Serial, ATA8-AST, SATA 1.0a, SATA II
Extensions, SATA Rev 2.5,
(actual serial number obfuscated)

Can someone explain why please ?

When I use seagate seatools, it reports both the USB-STORAGE and also
the internal HDD with the same  serial number (on windows).

BTRFS hybrid systems

[Bhasker C V]

Hi all
  I have an x86_64 kernel running with i386 userland rootfs.
 Long back I believe there were some fixes for btrfs-tools which ran
smoothly in this setup but after several dist-upgrades and long forgotten
command, the btrfs-tools commands have started to fail

for instance

$ sudo btrfs fi sync  .
ERROR: sync ioctl failed on '.': Inappropriate ioctl for device
$

Is there any fix for this ?

help needed with openssl please

[Bhasker C V]

Hi,

 I have some of my documents encrypted with openssl bf-cbc for
confidentiality. I however see that after a dist-upgrade my new system is
refusing to decrypting the data whereas my old systems are still decrypting
the docs fine.

on my new system:

$ cat a.enc  | openssl bf-cbc -d > /tmp/a
enter bf-cbc decryption password:
bad decrypt
4146137408:error:06065064:digital envelope routines:EVP_DecryptFinal_ex:bad
decrypt:crypto/evp/evp_enc.c:529:
$ openssl
OpenSSL> version
OpenSSL 1.1.0c  10 Nov 2016
OpenSSL>
 9.0 streetch


whereas the "same" file in old system
bcv@nas:/tmp$ cat a.enc  | openssl  bf-cbc  -d > a
enter bf-cbc decryption password:
bcv@nas:/tmp$ openssl
OpenSSL> version
OpenSSL 1.0.1e 11 Feb 2013
OpenSSL>
7.9 wheezy

Obviously I infer that there is no problem with the encrypted file as-it-is
but has any defaults changed which I must now include in my command line
parameters ?

Sorry to get back to you all on this again. Its now nearly 4 days. Has
anybody had success in getting the packages of mate updated ?
My sources.list is

Re: seg fault on many applets

Hi all,

About mate again.
As per this https://sunweavers.net/blog/node/45 is says that ebnd of
Sept the packages must get fixed.
I however still find it difficult to run caja which is primary
file/folder manager.
and many other applets too are crashing.
Is there any schedule update which I can look forward to ?

Thanks. I can understand that the doc is about setting up a separate DHCP
server. However, I want to use network manager's functionality to create a
hotspot and also be able to control the dhcp range of this hotspot.
This is where I got stuck with the 10.42.0.1

network managet and 10.42.0.1/24

[Bhasker C V]

Hi all,

 I am at a loss to find out how to change 10.42.0.1/24 and 10.42.0.x/24 as
ip and dhcp range which is used by network manager when configuring a
wireless card as an AP. I dont see the setting anywhere and cant find a
valid doc in the internet too
Is this value had-coded in the source-code of NetworkManager ?

Has anyone got an experience of making Network manager work aas a DHCP
server with custom DHCP range ? please if you can share your experiences

thanks
Bhasker

The new user is also showing the same behaviour. Dialog boxes are not

Improper visuals after update

[Bhasker C V]

Hi,

  After an update I see that my dialog boxes are looking weird. I cannot
describe it but it looks as-if the contrast is lost or the theme is not
supported ? The boucing bars have gone missing but mouse over and clicks
work. This is especially bad with nm-applet. I use mate desktop

If anyone knows please can they  tell me how to get this fixed ?

Network manager (again)

[Bhasker C V]

Hi

  I am finding it difficult to settle on a good network manager which
can work for my case

1. My home dir is luks/ext4 and mounted manually after logging in for
the first time
2. My GUI is started after mounting my home dir and by manual startx only

I could never get my network manager to store passwords in the user dir.
I do not like the passwords stored in
/etc/NeworkManager/sytem-connections with plain passwords visible so
anybody can open them if they have physical access to the machine/disk
(usb live stick etc., )

If I pull up the properties of nm-applet and change the option to 
"Store password only for this user", nm-applet does not connect since
the keyring is no automatically unlocked due to startx

Can anyone help me with fixing this network-manager so the passwords are
stored per-user in my luks home rather than /etc/...  OR tell me how to
enable nm-applet to automatically trigger opening gnome-keyring ?

Where does the file get 93M space ?
I know the VG is 96M but the pool created was max 40M (also VG still
says 48M free). Is the file exceeding the boundaries ?
or am I doing anything wrong ?

Where is grubx64.efi

[Bhasker C V]

Hi

 I have been trying to find out where does the grubx64.efi come from ?
I have a system which is EFI boot. I can see that after grub-install
/boot/efi/x86_64-efi/core.efi is created and this is copied as
efi/EFI/debian/grubx64.efi

What I am failing to understand is where does this core.efi come from ? I
went through all the packages in the netinstall cd but could not find
a single package providing this file

also dpkg -S does not return positive results about the owner of this package.

Please could someone tell me how this file gets into my system

Thanks

BTRFS failed

[Bhasker C V]

Hi,

 I  have a home dir btrfs on top of luks
 Just recently there was a power falure to the machine and since then the
volume is not mountable

1) I tried ro,recovery,nospace_cache,nospace_cache option of mount
2) I tried btrfs-zero-log -y -v
3) btrfsck  --repair --init-csum-tree

But for sure there is data in the volume.
btrfs-show-super reports nicely the btrfs filesystem

Can someone help me how to proceed further ?

Annoying Keyboard switch

[Bhasker C V]

H,

  I have a system where I switch keyboards a lot (from UK to US etc.,)

  I use sid with mate-desktop-environment
 The keyboard preferences allows an applet in system tray to switch between
keyboard types.

 When I swtich keyboards, however, I see that the keyboard variant resets
back to US even if last keyboard selected was UK and the system was
shutdown.

Any tips on how to retain the last keyboard variant ?

Thanks

Re: Debian CPU heating up no apparent cpu activity

[Bhasker C V]

Thanks all for inputs

SOLVED !!!


1) The fan is fine in my system. The fan does not run and CPU remains
cool when used with the SSD based USB device but CPU was only heating
when using with USB-SD card based OS. So this is NOT a hardware issue

The problem is that mine is a hybrid nvidia-optimus  (bumblebee).

Now, I had disabled nouveau (modprobe.d blacklisted) which caused (I
guess IMHO) the GPU to be switched off thus offloading all tasks to
the CPU.

The moment I loaded nouveau GPU got enabled and the good nice
neighbour to CPU started helping CPU.
Now my CPU is nicely running at 55-60C as expected. I can hear the
fans spinning down the instant nouveau is loaded !!!

Again, I really appreciate and thanks to all for your inputs

Indeed it must have been as you state but I did not want to do a

will cause a lot of compilication. I went ahead and installed a fresh
system and then copied the kernel and initrd into the SD card.
I however do not remember why I disabled nouveau ... must have been
thinking something else...

But yes.. in SSD nouveau was enabled and in SD it was not. That caused
a major difference.
I am also amazed on how GPU contributes to the CPU task offloading
even if graphics is not used (text only mode)

 Thanks all for inputs

 SOLVED !!!


 1) The fan is fine in my system. The fan does not run and CPU remains
 cool when used with the SSD based USB device but CPU was only heating
 when using with USB-SD card based OS. So this is NOT a hardware issue

 The problem is that mine is a hybrid nvidia-optimus  (bumblebee).

 Now, I had disabled nouveau (modprobe.d blacklisted) which caused (I
 guess IMHO) the GPU to be switched off thus offloading all tasks to
 the CPU.

 The moment I loaded nouveau GPU got enabled and the good nice
 neighbour to CPU started helping CPU.
 Now my CPU is nicely running at 55-60C as expected. I can hear the
 fans spinning down the instant nouveau is loaded !!!


 So the driver was not disabled when you tried on SSD? If the purpose was to
 identify the cause for a problem,  then why would you enable a driver on
 SSD and disable it on SD; instead of keeping it either enabled or disabled
 on both? You would keep the system on SSD the same as it was on SD, so
 that the only difference would be the device the OS is running on, which
 would help narrow down the problem and identify it's relevance to storage
 device used...

 Cheers!
 Burhan

Debian CPU heating up no apparent cpu activity

[Bhasker C V]

Hi,

 I am trying to create 2 systems (both are portable and works on USB)

1. USB-SATA bridge SSD with linux kernel 3.19.0 (self compiled).
   this systems works fine and the operating temperature on the DELL
machine I am using is about 54C to 60C

2. USB-microSD with MicroSD card (sandisk 32GB).
   this system when it works starts heating up !!! temperatures sore
to 80C.(in a matter of 2-3 minutes)

BASE CONDITIONS (common for both systems):
* Both the systems are jessie
* Both are running idential kernel and initrd (infact exact binary
copies on both)
* top shows very low CPU utilisation
* iotop shows occasional  R/W but not too much of write/read (less
than 0.1 kb/sec)
* both are currently text mode only
* system is DELL Q15R core-i7-2630QM (see cpuinfo in the end)

Re: Debian CPU heating up no apparent cpu activity

[Bhasker C V]

I do not see anything. top does not show anything in the top list ...
it is just that when arranged in high to low CPU usage, the first
process it shows is a kernel process and it is using 0% or 0.5% of CPU
This really puzzles me
Who can take up CPU time without showing up themselves in the 'top'
thereby heating the CPU but hiding itself

Re: Debian CPU heating up no apparent cpu activity

[Bhasker C V]

could it be because with USB-SSD the kernel detects it as drive (smart
works and also does hdparm) and uses DMA whereas in USB-SD kernel
detects and attaches to usbstor but then has to do pio and cpu
intensive low efficency transfer methods rather than DMA ?
This means that kernel is doing a lot of job to write/read to usb and
will not show up in top ... but still since CPU is being used
constantly CPU gets heated up 
just a hypothesis ... someone can comment on this

if that is the case how to force UDMA for usb memorystick kind of devices ?
tried googling ... no answer

Re: GRUB legal disclaimers before the menu

[Bhasker C V]

I did try the multiple-menu entries but the moment I put a dummy entry
the menu entry does not appear at all !

The only other way is painfully use the echo command

echo line1
echo line2
..
sleep 5

which will delay the boot by 5 seconds unconditionally.

One of the suggestions on IRC was to modify the code to do this but I
do not want to do this on production servers since once modified then
it becomes my responsibility to maintain and patch the grub code.

   Googled - no info available.

 Try putting a disclaimer inside the menuentry, i.e.

 menuentry legal_goes_here {
  echo 'You shouldn't be here'
 }

 This looks like a good idea; in fact, it may be the only way of getting
 close to what the OP wants. Hpwever, the problem might be the length of
 the disclaimer for setparams (legal_goes_here). The GRUB menu
 displays the text on one line and, with line wrapping not apparently
 available, much of it will not be on the screen.

 I would also query the purpose of the second line in the stanza.

hosts based open ssh authentication

[Bhasker C V]

Hi all

 I have a system in a cluster (experimental) and there are a lot of
debian machines which depend on this system and must be able to ssh into
this system

I wanted password-less authentication and looked on the internet.
Almost all the examples and help shown involves setting up
ssh_known_hosts which I am trying to avoid (cumbersome in a large
network where we dont know who will need access).

Anyone got this working just plain without adding known hosts ? I do not
want to add each and every host to ssh_known_host. Essentially I want to
have an open access to one of the servers via ssh.

I tried running sshd as root and adding

auth sufficient pam_rootok.so

to pam ssh and login
but that did not help.

Thanks

Bhasker C V

problems with bridge name

[Bhasker C V]

Hi all,

 For some reasons, I have chosen the bridge interface name as 'he' in my
previous machine which is running livirt now. I am creating a new machine
so that I can do live migrations using libvirt.


 From wheezy I am seeing that in /etc/network/interfaces, using interface
name as he causes issues. Any other name works but the command

ip link set dev he up

fails if the interface name is he.

???

Has anybody come across this issue ?

Can somebody tell me if there is anything wrong with what I am doing ?


 /etc/network/interfaces

iface he inet static

cyrstalHD with debian

[Bhasker C V]

Hi all,


 Its been 2 days since I have tried to compile every flavor of mplayer
(mplayer, mplayer2 with stock ffmpeg and the ffmpeg download from the
ffmpeg site) but none of them are compiling cleanly. It is as-though
mplayer is not being maintained for crystalHD


Coming back to the default debian installation with custom kernel
(3.5.3) I end up in a situation that mplayer jitters for HD video 
(1080p) although windows runs fine and smooth video using the

crystalHD decoder.

I downloaded the drivers from Broadcom site and compiled them for my
system. I get this in the dmesg when the driver is loaded.

Despite this the stock mplayer has issues from what I can see in the
below command output.

my lspci output has this

Has anyone got HD video smoothly running on a Atom N550 based system
which has a crystalHD decoder in it ?  Any help will be appreciated. 
Thanking in advance.

IRQ conflict IRQ0 network card.

[Bhasker C V]

Hi,

 I have a old PC (AMD athelon 3000+) which has an onboard network card
(gige-tg3) kernel 3.5.0 debian squeeze.

03:16.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S
[Rhine-III] (rev 86)


 When I do an ifconfig eth1 up (eth0 is another external card) I get
this error


[  408.536851] genirq: Flags mismatch irq 0. 0080 (eth1) vs.
00015a20 (timer)

I tried to google for this but could not get any good fix information
for this issue. The card is not working as of now but was working fine
with FreeBSD kernel.

Has anyone encountered this before


I have tried hpet=none (just to score off the hpet IRQ and this card IRQ
clash)
I have tried pci=biosirq

When I load the driver these are the messages

IF anyone has got an experience dealing with this issue can you give me
inputs please ?

Re: Re: IRQ conflict IRQ0 network card.

[Bhasker C V]

Got this working.
The problem was local APIC was not enabled in the bios. Once enabled
everything started to fall in place.

thanks all for your inputs and help

Have you tried with Debian stock kernel (2.6.32) or the backported one
(3.2)? :-?

Is the network card working despite the error? I mean, kernel can be very
verbose but some messages are also harmless, just informative.
 
 I tried to google for this but could not get any good fix information
 for this issue. The card is not working as of now but was working fine
 with FreeBSD kernel.

Ah, then the problem is for real :-(

 Has anyone encountered this before

Google suggests the message comes from kernel 3.5.0, I would look for any
specific patch that solves this, if any.

USB mounts not presistent

[Bhasker C V]

Hi all,

 In the latest wheezy install of debian (K 3.2.0-2-amd64) I am finding
that unlike before, when a USB disk (especially a USB external 2.5
harddisk) is mounted, it is not persistent after a suspend resume.
Has anyone faced this in wheezy or am I missing anything here ?

The same is happening with the case of cryptsetup devices using USB
where the dm-crypt device mapper mapping is still present but the USB
device link is dead !

BD-R not getting finalized

Hi all,

 This is the second BD-R where growisofs fails during the last stage of
finalizing the disk
 I am using a USB external writer but I do not see any USB related

I am not trying to rule out a possibility of error in the BD-R media but

Reading luks DVDs using cryptsetup

[Bhasker C V]

Hi,
 
   I have been using DVD+RW disks for storing data which are  luks
encrypted flat files.
   I have been successful in future with the below command but in the
newer version this fails with the error as pasted below. Is this a bug or
 was this deliberately introduced ? Can someone share some info on this
please ?


$ sudo cryptsetup luksOpen /dev/sr1 dsk --key-file ./key
device-mapper: reload ioctl failed: Invalid argument
$ sudo file -s /dev/sr1
/dev/sr1: sticky LUKS encrypted file, ver 1 [aes, cbc-essiv:sha256,
sha1] UUID: ...
$ cryptsetup --version
cryptsetup 1.4.1


Where /dev/sr1 is the dvd-rom drive with the disk containing the  raw
flat luks file written using growisofs


whereas in cryptsetup version 1.1.3 (old etch/squeeeze) this worked
perfectly well.

Help needed please with luks volume

[Bhasker C V]

Hi all

 Sorry for the cross-list posting; I think this will help.

  I have a luks formatted volume and on debian this volume just stopped
working after a  dist-upgrade
 The error reported is as below


$ sudo cryptsetup luksOpen /dev/sdc dsk
LUKS keyslot 6 is invalid.
LUKS keyslot 7 is invalid.
$ cryptsetup --version
cryptsetup 1.4.1
$ uname -a
Linux bcv 3.2.9 #1 SMP Sat Mar 10 20:36:56 GMT 2012 x86_64 GNU/Linux

Whereas when used in an older version (in my office) this disk works
perfectly fine and I am able to view data.
This home system of mine running debian with cryptsetup version as above
has a problem and so I am not able to
take the data out wheras cryptsetup version cryptsetup 1.0.6 (which runs
kernel 2.6.39-rc6 ) works perfectly okay.

I am stuck with not able to see my private data at home.

Can someone help please ? Or is this a bug introduced in the newer
versions ?

thanks

Clipboard issues

[bhasker]

Hi all,

  I am seeing this issue on my debian wheezy/sid. The clipboard contents 
are disappearing when the window is closed. Can someone help me please if 
they have to faced this issue ?


 Steps:
open any window application (even xterm )
Mark the contents of the window (which is copying )

a) Close this window and open another window and try to paste the 
copied text. The copied text has disappeared and last text is remembered 
and pasted!

b) before closing the window if you try to paste the paste works fine.

thanks all

The PREROUTING or the INPUT (iptables)

[Bhasker C V]

Hi all,

 I am asking 2 questions in this and apologies if this is a bit too much 
in a single mail.


Q1)
 I came to understand that the first rule to take the hit is the 
PREROUTING nat table (after the mangle). So in case I want to do a DNAT of 
input packets to one of the interfaces in another machine on the same 
network as the router, then, I can apply a DNAT rule in the PREROUTING. 
But if I want to also select that the packet must be DNAT'ed only if
the input is from a specific ip address, then applying the DROP rule for 
'anything other-than' type of packets is not effective in the INPUT chain 
since the packet traverses the routing decision and goes into the FORWARD 
chain and goes outgress...


So out of many experts here, I just wanted to take an advice on where to 
keep the DROP/REJECT firewall rules ? Is it in the PREROUGING or the 
INPUT? If I keep it at INPUT then the packets which needs to be DNAT'ed 
will traverse bypassing the INPUT rule.


also,

Q2)
 I was guessing from the man pages of iptables that I can give multiple 
source ip addresses in a single stretch by seperating them with a ',' . I 
couldnt apparently do it, and  below is the command line I used. Could 
someone point me on what is the mistake I am doing please ?


iptables -A INPUT ! -s 1.1.1.1,1.1.1.2 -j ACCEPT

This command is trying to resolve 1.1.1.1,1.1.1.2 ignoring the ',' in the 
ip addresses taking this as a complete name.

root@mac1:/# iptables -A INPUT ! -s 1.1.1.1,1.1.1.2 -j ACCEPT

What I do is use the PREROUTING table to set up the general forwarding,
and use the FORWARDING and INPUT tables to actually allow or block
traffic. A rule for PREROUTING could be this:
iptables -t nat -A PREROUTING -i $EXTIF -p tcp -d $EXTIP -m multiport
--destination-port 20,21,22,80 -j DNAT --to-destination $WEBSERVER


So if I am blocking an IP from entering, I have to do it both in the input 
chain and also in the FORWARDING chain so that wherever it gets hit, it 
will be dropped. Thanks I will do the same


In this case forwarding ftp, ssh and http ports.
The forwarding and input tables should be used to block unwanted traffic
(or allow wanted traffic).

iptables -A FORWARD -i $EXTIF -o $INTIF -j ACCEPT
allows everything from outside to be forwarded to the internal lan in
this case.

An advice is to limit the rules to the smallest possible match, not
allowing anything to slip by that was unintended.
Yes I usually allow the needed IPs and block all others in a plain DROP 
rule. Thanks again.

Perhaps you are looking for the iprange module?
iptables -m iprange --src-range 192.168.1.1-192.168.1.254 -j ACCEPT
That allows you to specify a range of ip's.

Using the -s argument for source ip's, you can only give a single
address, however, it is possible to define a complete subnet like this:
iptables -s 192.168.1.0/24 -j ACCEPT
In other cases you'd need 2 separate rules.

Re: How do I set up compiz ? No xorg.conf anymore ?

[Bhasker C V]

Shirish,

 Can you try X -configure
 That will give you a base xorg.conf.new with auto-detected values (this 
file will be present in your home directory (/root/xorg.conf.new if you 
are running this as command as root)


 You can copy it to /etc/X11 after backing up the old file in that location (if 
any)
 After this, try to you can install compiz and do

 compiz --replace

 If that does not work, it would start giving out messages which you can google 
out
 and start fixing it...

Re: Backing up email to a CD

[Bhasker C V]

If the tool you are looking for is to do a mirror of all the mails from 
IMAP erver to your local disk, then, toy can look at this


http://freshmeat.net/projects/imapsync/

This will create a copy of the complete mails in all your folders in the 
imap server to your disk so that you can later copy them into a DVD with 
the burner of your choice (i particularly like mkisofs and 
growisofs/cdrecord appropriately)


In case it is pop, then it is easy. Use the mail folders present in the
client machine which will contain all the mails.

kvm Vs qemu-kvm Vs qemu -enable-kvm

[Bhasker C V]

Hi all,

 I could not google out and get an effective information on what is the 
difference between the above. Can someone explain me please ?


 I am talking here about the user space application only and not the 
kernel module or kqemu.


 I can see kvm is supplied by the kvm developer site which is a modified 
qemu


 I can also see qemu-kvm which is installed in the machines by package 
managers


 I can also see qemu (the original version from qemu.org) has support for kvm 
using the switch -enable-kvm

 In all the 3 cases i can see all of them using the kvm_intel module (mine 
is an intel machine).


 So what is the difference ? Qemu (from the qemu.org by Fabrice Bellard 
) also supports kvm and the kvm site gives its own kvm whcih is also 
modfied qemu. The qemu from the qemu.org site looks better since it has 
support for gigabit ethernet emulation as-well-as it can do USB 2.0 
emulation which I am seeing it lacking in kvm versions (atleast untill 88)


 what to use ? kvm or qemu with -enable-kvm ? is there a difference 
between these two in the subject of performance ?

I wonder if nowadays UDF could be used to deal with this problematic :-?

Tried it. UDF from udftools(1.0.0b2 ) on etch creates an UDF which is not

I am then left only with an option to use the backup only with linux. For 
data in windows, ntfs partitions
can be mounted in linux and then copied over to the backup disk. The external 
disk can _only_ be used in

linux and not in windows.
Finally found issue was with the SATA to USB converter which has issues 
when used for a long time period and heats up. Once I moved to another USB 
casing things starting falling in place. So, it is a hardware issue



 TO SUMMARISE

 the best way to do it (if i can call it that) would be to use ntfs. Ntfs
supports most of the 'features' you would like to have after using ext2/ext3. 
NTFS (both kernel one and the ntfs-3g) works fine and can be used without 
any data loss issues if properly and carefully used.

File system for linux and windows

[Bhasker C V]

Hi,

This may not be debian-specific question, but with the group expertise, 
I think this would be a good reference for

anybody.

I think this question has been debated a lot but still there is no clear
information on what to do.

The question is, if you want to share data between linux and windows 
what is the best file system to use[plus adding

security complexity].

Using Ext3 on windows is good but has its limitations. This does not work
unless the ext3 file system is on a partition. The limitation comes when
using applications like freeOTFE which can read LUKS volumes. The volume 
is mounted as a drive but not detected as a disk

by any of the written
ext3 drivers in windows.

Using NTFS on linux and windows is cool. I have consistently seen that 
when there are large number of files, undoubtably,
ntfs volume goes corrupt and chkdsk simply removes files and creates 
data loss. I do not have any clue on when the FS goes
corrupt (either when writing using linux or when using in windows - Used 
ntfs (kernel), ntfs-3g ... all in vain).


Anyone can recommend VFAT. FAT32 being supported by XP and well 
supported by linux makes it a good candidate. The problem
with FAT32, I guess (correct me if I am wrong), there is no support for 
case-sensitive file names in the FAT32 file system.


So, the question... what FS to use which is good and reliable in both

Yes, I have included the VNC server logs in my original post. If you

Seeing this, are the font directories installed properly ?
If yes, I could remember that there was an issue with starting vnc on 
fedora which could be fixed by finding the 'fixed' font directory and 
passing the name of that directory as an arguement to the tightvnc server

something like

  [tight]vncserver -fp path  :1

I have two 1TB drives, both with two partitions on them. One drive has

I have never had a corrupted NTFS partition from using it with ntfs-3g.
I've been using the setup I described above for years now, and the NTFS
partitions are used intensively on both Windows and Linux as download
partitions (usenet, torrents, etc).
  
I think this is the near best solution. This is the 3rd time I am trying 
to capture all data (around 10,000 files)
from my linux box into the luks ntfs partition. Everything works fine. 
There is no file corruption. But it all
starts to cruble the moment you use chkdsk. Chkdsk starts deleting lots 
of files and says they are corrupt
and then on the next run it salvages files saying they are orphaned. On 
total, I lose a lot of files.

with FAT32, I guess (correct me if I am wrong), there is no support for
case-sensitive file names in the FAT32 file system.



Don't expect NTFS to be case-sensitive either when using it with
Windows. I had two identically named folders, only with a single letter
in a different case. Windows could not distinguish between the two folders.

I would not use FAT32 if you didn't have to. It fragments like mad, and
has no built in journaling to protect from data loss in case of a power
outage.

  

So, the question... what FS to use which is good and reliable in both
windows and also linux  ?



Really depends on what OS you are using the most. Using EXT3 means you
lose the security information when using it with Windows. The same with
NTFS and Linux. Both just ignore the information. If this is not an
issue, then I would suggest using NTFS, because Windows supports it
natively, and ntfs-3g is still being developed, unlike the EXT3 drivers
for Windows.

  

Is there any file system in linux which can work in windows also
(meaning it can be read and optionally written-to in
windows even if the
FS is not in a partition) ?




I have no real experience with this, but I have a file-based Truecrypt
partition in NTFS, and use them with both Linux and Windows.

I wonder if nowadays UDF could be used to deal with this problematic :-?
  
Tried it. UDF from udftools(1.0.0b2 ) on etch creates an UDF which is 
not working with windows.
I am then left only with an option to use the backup only with linux. 
For data in windows, ntfs partitions
can be mounted in linux and then copied over to the backup disk. The 
external disk can _only_ be used in

linux and not in windows.

Greetings,

ext3 mkfs issues with a fresh file system ?

[Bhasker C V]

Hi all,

This is strange.
I created a file system on top of luks and does not have any data yet.
The very first fsck gives an error in the freshly created file system !
