I want to create a script to insert the fstab and hostname in a textfile of multiple servers on the network without a password. The servers are situated in a text file. So i want to read the text file line by line and write the output into another textfile.

I have prepared a script which will login to each server and search for a keyword.
I want output on same machine from where m running script.

We have a requirement to configure multiple email gateways, for mail accounts configured on linux server. the application will trigger mails (bulk mails) and we would like to configure multiple email gateway to be used.
we decided to do it this way.
In dns we would create MX records like
yourdomain.com. 3600 IN MX 20 realmailserver1.yourdomain.com.
yourdomain.com. 3600 IN MX 20 realmailserver2.yourdomain.com.
where realmailserver1.yourdomain.com. and realmailserver2.yourdomain.com. will be our email gateway.
and internally on our linux server (from which mail is sent) if i specify multiple smart hosts like
define(`SMART_HOST',`esmtp:realmailserver1:realmailserver2')dnl
have a look at the following thread story and please clear my doubt.

Script is being run on Linux Red Hat,
In one of the grep/awk's the output (currently) are 2 columns (min max), i.e....| awk '{print $1, $2}' | sort -u which outputs (e.g.)
The number of "min max" pairs varies from file to file. Want to output a single column of unique numbers from the min max pairs & get the number of them for input to a file...i.e...
Where <PROCESS> is some process/technique that will generate a single column of integers (increment of 1) to pipe into the next one (sort -u)
i.e. (example from above)
Have tried command seq - only works for single pair input i.e.
Is there any command like seq etc which will output a single column based on a input of min max numbers (increment 1) to pipe onwards to next command?
I have 16 linux servers that use /etc/hosts files to see and talk with each other. I'm adding servers to this pool of servers. It is required to do host resolution via the /etc/hosts files. DNS or NIS are not alternatives. Aside from manually editing each of the 16+ /etc/hosts files every time I add a server or editing one /etc/hosts file on one server then scp'ing it to all the other servers, is there anyway to edit the /etc/hosts on one server and "push" it onto the other servers that need the new /etc/hosts file?
Everywhere I've looked on the Net, there hasn't been any suggestion except for the options I mention here.
Or am I just whistling in the wind?
What is the best way to go about setting up multiple virtual hosts on the same box, one using http and one using https/ssl? I'd like to serve them from the same ip address if possible; I know it's possible in apache 1.3.
View 2 Replies View RelatedI am somewhat familiar with SGE (Sun Grid Engine, now Oracle Grid Engine) commands but am having a problem when running parallel jobs.
Present Machine configuration:
machine I - 12 cpus
machine II - 12 cpus
machine III - 12 cpus
.... so on ...
One_machine - 16 cpus
(I have all machine of 12 cpus and 1 machine having 16 cpus)
I want to schedule jobs on these machine such that if I ask for 12 cpus - my jobs should execute on any of the machines which has all 12 free cpus (eg machine I or machine II) in this case.
Eg. suppose I ask for 24 cpus
Option I : 12@machine1 12@machine2 ----- I need this
Options II : 10@machin1 10@machine2 4@machine3 ---- I don't need such a distribution
Hence, Option I is ideal here. Also, when running 12 jobs on machine1 (say) - even if all 12 cpus are not being used at some instance of time, none of the 12 cpus should be freed.
In short, until my run finishes, all blocked cpus should remain blocked.
If you may understand, the purpose here is to run some performance tests.
I'm using 'qrsh' to launch jobs.
I am trying to configure dhcpd to provide two different pools of IPs- one for dynamically named hosts specific to MAC addresses, and another for everyone else.So, a machine with X MAC address connects, gets an IP from e pool, and the server updates DNS with the address under a specific hostname.For the other pool, it just assigns the IP, no DNS updates.The "class" function doesn't appear to allow anything but pattern matching, and I can't find anything that specifies what "allow" and "deny" options therere for the pool command.Here's my config so far - will this do what I want?
Code:
key dhcpd {

I have set up a SSL site for my default Apache server. But I want to set up multiple SSL sites for multiple IP based as well as Name based Virtual hosts. Is there a way where in I can include definitions for SSL certificates and keys within the Virtual Host directive in the httpd.conf, so that I can specify separate key and cert file for every Virtual Host.
View 11 Replies View RelatedI have a server that host's several sites, recently I had to create a new server because the old one isn't good enough for me. Ive installed apache2 on the new server and moved all the files from one server to the other. I'm making tests in my local lan so I've edited my computer's hosts file to point to the name of each site to the local ip of the new server:
192.168.1.85 www.mypage.com
192.168.1.85 svn.mypage.com
192.168.1.85 trac.mypage.com
I have all the site definition files in /etc/apache2/sites-available I also have the used a2ensite to enable each page.
Whenever o use my browser to try and access each of the sites I always get the svn.mypage.com page and none of the others.

I'm trying to pass multiple dpmains thru one ubuntu server to various hosts on my local network.
[url] should be sent to the /var/www folder on the local host.
[url] should be forwarded to an IIS box on my local network (owa.nunya.local)
[url] should be sent to another ubunto box on my local network (smtp.biznet.net)
I have tried placing VirtualHost entries in /etc/apache2/sites-available/default and [url]and [url] both work but [url] gets forwarded to the c:inetpub folder on the IIS box.
I am trying to make a bash-script for auto-logins on several hosts, seems there is a problem with the quotes and I can't figure it out. I've experimented with singles and doubles but no luck yet. Below are two variants with respective outputs. In both cases the output of echo works fine if I copy and paste it to a prompt, but when executed from the script it falls down.
* Only one case-clause for testing...
* Not possible to use passwordless key-login
#!/bin/bash
PASSWORD="my_password"
case "$1" in
"example1" ) HOST="example-host-1"
echo $HOST;;

if [ $HOST ]
then
COMMAND="expect -c 'spawn ssh $HOST ; expect assword ; send $PASSWORD

echo $COMMAND
exec $COMMAND
else
echo "No host argument"

I'm trying to use ssh-keyscan to get some known_host file population going on, but I have a ton of hosts I want to scan, all with multiple aliases in /etc/hosts.

View 1 Replies View RelatedI'm not sure if this is best done in Perl or Bash. I'm thinking surely someone else has created something close to what I'm looking for. The results of the script would be that someone would kick off "linux_hosts.sh" r whatever you want to call it, then a top "folder" of options (with hosts contained within each of these top menu choices), then, based on which number corresponds to that top level, they're presented with a set of linux hosts that are relevant to that top level name. Example:
$ linux_hosts.sh

I've browsed the internet, but haven't found a satisfying answer. Hope this forum can help me in the right direction.I'm exploring the possibilities of creating a program that manipulates (writes to) two different video cards.I program in C and hope to avoid high level libraries like Xlib to keep the mem footprint as low and the performance as high as possible. Windowing is not important no desktop environment will be used. Be able to write two pixels (one to each screen) to would do.
How would I go about?To give an idea of the solution I'm looking for:One screen will show thumbnails of images on the hard drive. Clicking an thumbnail on display A will show the selection full screen on display B. On a laptop; preferably thumbnails on the laptop screen and the selected image on the external monitor.Is this possible with just low-level libs or do I need X or some third-party software to make life easy?
Code: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?
I am trying to learn how to pass more than a one-command startup for gnome-terminal.
I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
USAGE="
${0##*/} [-x] [-g]
code....
However, running with the -g option to invoke gnome-terminal, I get a "There was an error creating the child process for this terminal" error.
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
