Heh; I would have suggested using openwrt or openswitch instead but
sometimes that's not an option. [I've personally had to deal with this
issue for older hardware's OOB management stacks.]

There are. Both sides exchange a symmetric session key to use for the
connection. The public/private key which can be used with SSH has
nothing to do with this.

What do you mean? Just create ~/.ssh/config and put a Host statement
like above inside it.

It needn't be FOSS for you to download a newer version from the Cisco
website. (Only with a valid support contract of course.)

No, this is not the solution, as this will a) set this for every
connection and b) restrict the Cipher list to *only* this insecure
cipher.

Please read "man ssh_config". The Ciphers statement recongnizes + and -
as prefixes to add or remove values without replacing the whole setting.

Sounds quite reasonable. Having a lame algorithm for just one host'll
be no problem. But there's no 'config' of any sort in there.

> The real solution is to upgrade to a more recent version of IOS.

IOS is way not FOSS. Lovely software, though.

[SOLVED] -- there seems to be a lot of chatter about this on the web.

In /etc/ssh/ssh_config, I added 2 lines at the bottom of the file:

KexAlgorithms diffie-hellman-group1-sha1
Ciphers 3des-cbc

(3des-cbc is one the router offered)

Then I rebuilt the keys and restarted ssh. Worked.

I don't think I set the weak algorithm to just the router, though, and
I doubt this is as good a config as suggested. But I didn't have to
figure out the ~/.ssh/config problem, and I'm back on the air -- until
next openSSH upgrade, I suspect :-)

Thanks much for the help and explanation.

Generally, what happens is that older switches and hardware run ancient
versions of ssh which don't support modern encryption algorithms.

Usually that means that for that specific host, you have to advertise
specific host configurations, like so (where cisco1841 is the switch's
hostname):

Host cisco1841
 KexAlgorithms diffie-hellman-group1-sha
 Ciphers aes128-cbc,3des-cbc
 MACs hmac-md5,hmac-sha1

in your ~/.ssh/config and then connect to the machine like so:

ssh cisco1841;

If it doesn't work, run ssh -vv cisco1841; and see what is being
advertised, and adjust your options to suit.

The real solution is to upgrade to a more recent version of IOS.

buster ssh problem

[Glenn English]

buster, seems to be all hosts can't talk to Cisco router

I'd like to get into my Cisco 1841 (IOS 12.4) router with ssh like I
have for a decade or so. But buster's ssh says there's no useful
encryption algorithm -- says the offer is diffie-hellman-group1-sha1.
So I looked around a bit, and the openssh website says that's a
insecure algorithm, but I can enable it if I want to by putting some
text in ~/.ssh.config. Except there is no ~/.ssh.config. I created one
and put what I think is the recommended text in it, but no joy.

I put 'KexAlgorithms +diffie-hellman-group1-sha1' in
/etc/ssh/ssh_config, and ssh still says it can't find a good
algorithm, and gives me another list of possibilities. I assume that
list is coming from the router, and I have no idea what 'Kex' means

Anybody know what's going on? And how to fix it? Should I just give up
on ssh and use telnet? (The router's in the next room on the other
side of an Ethernet switch, so there's not much chance of crackers.
But a civilized admin much prefers ssh over telnet.)

most modern desktops will offer a tool to react when disk (usb) is plugged
in and if encrypted ask for password to decrypt. IF there is lvm they will
handle the lvm automatically

Manually it can be done as follows (presumably the disk was encrypted with
luks)

1. plugin in / connect the usb to the computer
2. cryptsetup luksOpen /dev/sd1 cryptedDisk
3. vgchange -ay cryptedDisk
4. mount /dev/mapper/cryptedDisk- ...

reverse

1. umount /dev/mapper/cryptedDisk-
2. vgchange -an cryptedDisk
3. cryptsetup luksClose cryptedDisk
4. unplug

*  - disk id (a,b,c,d etc)
*  - volume name

I found the easiest way is to use a GUI tool. My favorite is probably Gnome 
Disk Utility (package: gnome-disk-utility).

The Debian Wiki also has some information regarding LVM:

https://wiki.debian.org/LVM

I couldn't find it in the Debian Wiki, but the Arch Linux Wiki has information 
on dm-crypt and LUKS:

unattended desktop installation using gnome-boxes express install

[Federico Bruni]

Hi all

I'm not subscribed to this list.
I hope this email will go through and please use Reply to all so I can 
get your replies.


I'm not a Debian user anymore (switched to Fedora), but I'd like to 
report the problem described here:

https://bugzilla.gnome.org/show_bug.cgi?id=755297

Summary: when I install an official Debian LXDE image in Gnome-Boxes 
using the express install, GNOME is installed instead of LXDE.
Boxes wants to install 'desktop'. The Debian image turns desktop into 
GNOME, even if it's missing in the image. It should use LXDE instead.


I guess this should be reported to deb-conf or preseed?

Thanks in advance

Stretch : mount Jessie encrypted HDD via USB

[commentsabout]

Hello,

I'm trying to connect my old Jessie HDD via USB in order to transfer
files to my new Stretch system (details below). It does not work out of
the box because it is encrypted, how should I proceed?

- I only have a laptop;

- 1 old HDD with Jessie (guided encrypted LVM install);

- 1 new SSD with Stretch (guided encrypted LVM install), this drive is
in the laptop;

- 1 S-ATA to USB adapter.

Needless to say that I have the passphrase for both systems. I am
actually worried to damage the Jessie system by using wrong commands so
I am looking for help.

Thank you in advance :)

Tal cual, como dicen. No hay mayores riesgos. Podés acceder y copiar a través 
de un liveusb, por grub, clonar, pedirle al proveedor, etc... (supongo un

Si tenés acceso físico, no hay mayores problemas; se hace una copia de

Hello,
you should look at HDF(5).
https://support.hdfgroup.org/HDF5/

There exist free and open libraries (in debian repositories) to access HDF
files. There is a python binding wich makes it easy to integrate into
scipy/mathplotlib.

The lowest-common-denominator here is usually RRD [1], the Round-Robin 
Database. This will give you a fixed-size file containing various 
"buckets" for data at specific intervals (for example every 5 minutes 
for a day, every hour for a month and every day for a year). Lots of 
programs can read and write RRD because it's been stable for ages.


If you want something a bit more new/capable/interesting, there's 
whisper [2], the TSDB for carbon/graphite. Or OpenTSDB [3], or InfluxDB 
[4] or Prometheus [5].

when you have chosen the tool that will do the work, look at what format it
accepts and dump the data in this format.

from what you said it might be done in xml or DB if there are internal
relations

I am not familiar to Xfce4, but what I don't understand if you use the Xfce4
login manager or alike to spawn the vnc server.

In my setup each user has a vnc-run.sh script that has a dedicated VNC port

For example user with id 1005 gets vnc port 5905

#!/bin/sh
vncserver -geometry 1440x900 :5

If this runs once the user can connect always and from everywhere to port
5905 or in the vnc terms server:5

I plan to produce some time series data and i would like it to be in a
form that makes it easy or effortless for pre-existing programs to
plot or even process further.

The data would consist of a few hundred to a few thousand time points,
and for each time point there would be a half-dozen to a dozen values.

So conceptually it would be something like a csv file with a few
hundred to a few thousand rows, and a half-dozen to a dozen columns.

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

$ ls /usr/share/fonts/X11/misc/gohufont-*
/usr/share/fonts/X11/misc/gohufont-11b.pcf.gz
/usr/share/fonts/X11/misc/gohufont-uni-11b.pcf.gz
/usr/share/fonts/X11/misc/gohufont-11.pcf.gz
/usr/share/fonts/X11/misc/gohufont-uni-11.pcf.gz
/usr/share/fonts/X11/misc/gohufont-14b.pcf.gz
/usr/share/fonts/X11/misc/gohufont-uni-14b.pcf.gz
/usr/share/fonts/X11/misc/gohufont-14.pcf.gz
/usr/share/fonts/X11/misc/gohufont-uni-14.pcf.gz

Can someone help please ?
