 Actually, which services should I check first if our server goes down?


AFAIK there is no straight forward mechanism. Implement a good logging
mechanism for each of the services, and write a script which monitors each
log and takes periodic backups. Once the server goes down, check the logs.
Other than the log file of each service, monitor the system log too, so that
you can see if the temperature has gone too high (or other reasons).

Re: [Ilugc] to calculate time taken by process

Each of your insert statements sqlplus -s user1/pwdsafe runs as separate
processes by themselves. So when you use the 'time' command, it calculates
the time taken for that process to complete. Isn't it so?

i would like to know how can i get the total cpu time  taken to execute all
 the statements .


Use the time command for your entire shell script then! (Assuming your shell
script executes only these SQL commands). If not, then a naive workaround
would be to put these insert commands inside a separate script and run the
time command for that script from your original script. I don't know if time
command provides a mechanism to find the time of a set of commands, check it
out :-)

 Has any one tried to configure as VPN the guest and host under VBox to

If you want to share files, then install guest additions and enable file
sharing in vbox. If you want to perform networking functions between the
host and guest, you can use the Internal Networking or Host Only
Networking options. These allow multiple VMs on the same host to
communicate with each other too.

If you have a single VM, then you could as well use the NAT option, where
by default 10.0.2.15 is assigned as IP of guest via DHCP and 10.0.2.2 is
the internal virtual interface's IP of host.

If an encrypted connection is what you want, then you can create a VPN
server and client design (using OpenVPN maybe) in one of the options
mentioned above. It's the same process as creating a VPN server and client
design between two machines in a normal scenario right, or am I missing
something here?

[Ilugc] USB device not recognized

2010-06-14 Thread Hrishikesh Murali
Hi,

I have a 2GB Transcend USB pendrive formatted with FAT32 filesystem. All of
a sudden today, the USB device did not mount when I plugged it in.

I checked lsusb and the usb device was recognized. But when I executed
sudo fdisk -l, the filesystem was not recognized. When I also executed
dmesg|tail, I found that the partitions were not recognized.

The output of the three commands can be found at 
http://pastebin.com/MHZtTRH6;.

I have used testdisk to recover data, but when I executed testdisk, only my
internal hard disk was displayed, I could not choose the USB device. Is
there a way to recover the data in the pendrive?

There is a binary available for linux in the VMWare website. I think you

serial key [ fake serials are also available, check out ;) ].

But rather than doing this, I strongly suggest you look at virtualbox, which

[Ilugc] Grub2 menu not seen in virtualbox

virtualbox, which all use grub2. I am not able to see the grub2 menu, the

timeout) and works perfectly fine.

[Ilugc] Chromium OS on Virtualbox hangs

Hi,

I am running Virtualbox 3.1 on Ubuntu 9.10 Karmic Koala i386 arch. I have

Previously, I was not able to log in and was getting the message Network

was that my virtual interface was not in bridged fashion.

Once I configured it in bridged mode, now the error message does not come

hangs in the login screen after I enter my google user credentials and press
Enter. I have searched up a bit, but haven't been successful in solving

There are a lot of issues you are talking about. It depends on what services
you are running on your server, what is the server configuration, etc.

1) Maintain a log of what is going on and watch it regularly.
2) Have only required services running, disable all other services.
3) Use secure services like SFTP instead of plain text FTP, and https
instead of http if possible and if necessary, so that MITM attacks are
minimized.
4) Provide authentication in whatever service you are providing.
5) Have proper and secure input processing wherever possible (to prevent
SQLi and XSS, etc).
6) Use firewalls and make sure you are secure against DOS and DDOS.

There are a lot more but it depends on what services you are providing.

2009-11-30 Thread Hrishikesh Murali
Hi,
I am running ubuntu 9.10 Karmic on my laptop. I've ran the memory test which
shows during boot (memtest86+) and it ran successfully. But after I had
installed a theme for grub2 (ubuntu theme), when i choose memory test during
boot time, the computer just hangs. I've checked and rechecked the path to
memtest86+.bin in grub.cfg, and its perfect.

   1) Is it a bug in grub2?
   2) Does anyone else have a similar problem?
   3) Is there any workaround for this?

I installed openchrome and now with mesa 7.5.2 3D package, I am able to have
OpenGL supported :)

I have also tried installing the mesa 7.5.2 package, but I didn't find any

[Ilugc] Via Chrome 9 HC IGP Driver For Ubuntu Karmic

2009-11-28 Thread Hrishikesh Murali
Hi,
I have a laptop with the VIA Chrome 9 HC IGP CN896/VN896/P4M900 as my video
card (on-board) and my OS is Ubuntu 9.10 Karmic Koala, i386 arch.

I am not able to find a suitable linux driver for it, I am temporarily using
vesa driver. I tried downloading the driver from the sites
   1. http://www.via.com.tw/en/support/drivers.jsp
   2. http://linux.via.com.tw/support/downloadFiles.action
After download, it says that the downloaded .tgz file is not in a valid gzip
format in both the links.

The data in http://kmuto.jp/debian/hcl/VIA/Chrome9+HC+IGP claims that my
graphics card driver is 'via-agp' and is supported in debian.

I also tried looking up on OpenChrome, but it claims it does not support
OpenGL.

Does anyone have the linux driver which supports 3D acceleration with OpenGL
support for this video card (or atleast the link from which they downloaded
it)? I have been searching for quite sometime, and I'm not successful.

I have also tried installing the mesa 7.5.2 package, but I didn't find any
difference.

First of all, thanks. Don't know why I didn't think of this earlier :)
Well, the first case:
http://linux.via.com.tw/support/downloadFiles.action
This was in bzip format, so i extracted it successfully and installed it. It
*claimed* that the installation was successful.
But, when I tried booting up the computer hangs. So i dropped to a shell
during boot and then when I said startx, it gave me an error saying Error
loading module 'viavideo' (No such file or directory). So I just removed
the xorg.conf file and now its the same openchrome driver which I am using.

The second case :
http://www.via.com.tw/en/support/drivers.jsp
This was also in bzip format. It contains the source and it only provides 2D
graphics, which is already supported with openchrome.

Anyway, one of the threads in ubuntu forums pointed me to try out mesa 3D
graphics driver. I will try it out and let you know.

[Ilugc] Help With OpenVPN

2009-10-12 Thread Hrishikesh Murali
Hi,
I am in need of help with OpenVPN here. This is the situation:

I have the VPN server running successfully on 192.168.1.1 and the
clients are connected to it (192.168.1.2 and 192.168.1.3).

Computer 1
-
  eth0 - 192.168.1.1/24 (This is the VPN server)
  tap0 - 10.222.222.1

Computer 2
-
  eth0 - 192.168.1.2/24
  eth1 - 10.1.2.1/24  (internal network is 10.1.2.0/24,
and this is the gateway)
  tap0 - 10.222.222.2

Computer 3
-
  eth0 - 192.168.1.3/24
  eth1 - 10.1.3.1/24  (internal network is 10.1.3.0/24,
and this is the gateway)
  tap0 - 10.222.222.3


I have enabled forwarding from tap0 to eth1 and vice-versa using
iptables on the two gateways and added this command in the VPN server
configuration file:
  push route 10.1.0.0 255.255.0.0

This adds a routing entry in each client when they are connected:
  route add -net 10.1.0.0 netmask 255.255.0.0 gw 10.222.222.1

On the VPN server, i have added the following routes:
 1) route add -net 10.1.2.0 netmask 255.255.255.0 gw 10.1.2.1
 2) route add -net 10.1.3.0 netmask 255.255.255.0 gw 10.1.3.1

By doing so, i am successfully able to ping from 10.1.2.x to 10.1.3.x.

My problem is that all the packets go to the VPN server and then it is
forwarded to the gateways. I feel this will result in too much load on
the VPN server as it keeps running and in burst traffic situations
(and might crash). Am i wrong in this assumption?

Is there a better way to do the routing, that is can I push the
routing entries 1) and 2) automatically from the VPN server onto the
clients whenever they connect so that traffic does not have to come
through the VPN server, it can go directly to the gateway?

If so, what is the command I have to specify in the VPN configuration file?

Also, I need to log traffic and detect burst traffic. I know this is
possible using iptables, and have tried it out. But, is there a way
where I can specify in the VPN server configuration file to
automatically push commands onto the client to prevent burst traffic
(DOS attacks typically)?

I must prevent computers from one subnet from DOSing the VPN server,
or the other subnets, or any computer in the VPN. How do I do this?

What is the difference between dev tun and dev tap in the VPN
configuration files? I know it specifies the tunneling device, but why
two separate devices? In what situations do I use each device?

I have also noticed this, in my VPN server configuration file, I have the line:
server 10.222.222.0 255.255.255.0
If I specify dev tun in both server and clients, the server starts
giving out ip's to clients from 10.222.222.5, but if I specify dev
tap in both server and clients, the server starts giving out ip's to
clients from 10.222.222.2. Why is it so?

What if I enable forwarding using iptables from eth0 to eth1 in the
gateways? Will routing from 10.1.2.x to 10.1.3.x work even then? If
not, why?

I know there are too many questions to be answered :), but it would be
really helpful if I could get some answers.

Hi,
Thanks for the replies everyone.

If all the computers are on a common ethernet segment why are you
 running a VPN between these machines in addition to the ethernet?
 (If you want to encrypt data by default you are better of switching
 all machines to IPSec.)


I want to test out the VPN server on the LAN first before deploying it on
the internet.

Re: [Ilugc] Aceessing files from windows server from linux?????

2009-10-01 Thread Hrishikesh Murali
To access files via linux, you have to use the samba client. Type this in
the Nautilus addressbar or the Connect To Server in ubuntu:
 smb://ip/share
This will prompt you for authentication if needed. Please do tell me if I am
wrong or there are other methods.

Re: [Ilugc] Firefox not browsing any pages

 In my office, I installed ubuntu 9.04, which is connected thro LAN
connection. But the server connection is windows  os. I cannot browse any

system.
 regards
 arulmozhi r

Hi,
First, please explain the problem in detail. Without proper information, the
community will not be able to help you.
Anyways, coming to your problem.

There are two possibilities:

  1)  Firefox is browsing in offline mode. You need to go to
File-Work Offline. Please uncheck this option.
  2) Firefox is not configured to send data via the office proxy.
You need to go to Edit-Preferences-Advanced-Network-Settings. In this
window, you need to set the HTTP proxy and port, and the proxy server and
port for other protocols also (if needed).

Other than these, please check if you are properly connected to the internal
network and also properly connected to the internet. Please approach you
senior officials if you do not know the details.

Re: [Ilugc] Restrict users commands

2009-09-09 Thread Hrishikesh Murali
Hi,

I don't know a direct method for doing this, but my suggestion is :

  1) Take the source code for these commands
  2) Modify it such that you get the uid, check if its the
restricted user. If so, exit printing PERMISSION DENIED, else continue
normal execution.
  3) Compile the source code, get the executable and replace it with
the original executable in one of the directories in your $PATH variable.

If there is a direct command to do this,  please do enlighten me. I am eager
to know.

 Dear LUGs,
   recently TNEB supplied CUG simcards to all
 Engineers. I have an mobile phone list which contain 200 numbers. I
 tried to make the entry in my simcard using wammu through Motorola
 SLVR L9 ( OS is ubuntu 8.10). After single number entry, It shows
 squire boxes in name  numbers in mobile. and also wammu shows
 Japanese ( or china) language or symbols in name column when
 retrieval.
  I tired it the same in kmobiletools ( Mandriva
 2009), but I couldn't make an entry phone.
 I need the solution to solve it.

   Any other way to feed numbers to my mobile? I hvae
 n list in the form of openoffice spread sheet. any script to do it ?

Do you need to publish your spatial models to other users over the internet?
During this webinar, Ian Anderson, Director of Remote Sensing at ERDAS, will
seamlessly work through a local government’s dataset, showcasing the entire
geoprocessing workflow.  This webinar will illustrate how to
*author*spatial data models in ERDAS IMAGINE,
*catalog* and *serve* these models as OGC WPS in ERDAS APOLLO and *consume*and
*use* the WPS in the ERDAS TITAN client and other web applications.

ERDAS provides the most interoperable geoprocessing services in the
industry. Users can run an entire model (such as change detection),
completely contained within a single WPS process. The complexity of the
algorithm stored under a single process is unique, enabling an end-user to
create on demand line of sight, elevation change, image change detection and
more.

hi,
instead of editing the grub menu everytime during boot, it would be better
if you could permanently apply the change in /boot/grub/menu.lst.

First, understand the basics.

root(hd0,0) points to the first partition in your first hard disk
root(hd0,1) points to the second partition in your first hard disk

so if windows vista is present in the 4th parition(just assuming) ...
in /boot/grub/menu.lst

add the following after the ubuntu menu items :
titleWindows Vista
rootnoverify(hd0,3)
savedefault
makeactive
chainloader+1

if any problem occurs or if i am wrong, please do enlighten me :)
