And I CAN'T EVEN INSTALL ANY SOFTWARE in any linux boxes to determine the remote OS name and version.Can you please enlighten me on how could I find out the OS version of remote host without installing any software or without login to that server.

Q=What will this do?
A=This will read from /root/Desktop/iplist (or anywhere you want to put the list) after it reads the ip it will ping the ip two times. If the remote host is up then it will write the ip to a log. If the ping fails it will display it on the screen, write the ip to syslog so that you can do remote logging, and last it will send the ip by email to a user or a group of users.
Code:
#!/bin/bash
#wrote by Zach Underwood feb-12-2011
#test and wrote on centos 5.5 with sendmail
rm -f /root/Desktop/iplog #This will remove the good iplog
exec 9</root/Desktop/iplist #put full path the file where ip list is. Make sure that the ips are listed one per line.
while read -u9 ip
do
ping -c 2 $ip > /dev/null 2> /dev/null # ping and discard output
if [ $? -eq 0 ]; then # check the exit code
echo "$ip is up" >> /root/Desktop/iplog #write the ip of the hosts that are up
else
echo "$ip is down" # will show on the screen the ips that are not up
logger -p auth.notice "$ip is down" # will write the down host to syslog
echo "$ip is down" | mail -v -s alert user@anydomain.com > /dev/null 2> /dev/null #will send mail users about host down

Up until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else

I got a bunch of machines (~10) that I share with my co-workers. I have appropriate .ssh file(s) set up so I don't get prompt for password when I try to ssh.Currently I ssh into these hosts and then do a top to check the load before I start using the machine. Because I don't want to be on a busy host.Can someone show me how to write a script that find a least-busy host given a list of hosts to check? (hardcoded is fine)

Mount the remote samba with multiple groups on the local system?Browse the mount from 1) with the terminal since I want to pass some files from samba as arguments to local programs.which runs through gvfs; but the newer gnome does not write to disk the ~/.gvfs anymore so I can't browse it in terminal.

I'm trying to connect to a Win XP computer via Remote Desktop/Terminal Server. (Note: WinXP refers to Remote Desktop, or RDP; Ubuntu uses Terminal Server client for this function.)
The problem is that my XP computer requires the use of Microsoft's RDP version 6 because it uses a Terminal Server Gateway. The TS client in Ubuntu is compatible with version 5, not version 6.
Is there a MS RDP version 6 compatible program/client for Linux?

I am trying to do a find/grep/wc command to find matching files, print the filename and then the word count of a specific pattern per file. Here is my best (non-working) attempt so far:
wc `find . ( -name "*.as" -o -name "*.mxml" ) -exec grep -H HeightResizableList {}` ;
Is there a way to specify to find that I only want text files (and not binary files)? Grep has an option to exclude binary files, so I thought find probably has a similar feature, but I've been unable to find it.

View 3 Replies View RelatedI have the following command:ssh $USER@$HOST "ls /ops/pkg/ec/`grep "PKRTS" /ops/pkg/ec | awk '{print $1}'`* > /tmp/tmp_file"What the above SHOULD do..is, ssh to the host then execute the command.The command should first execute the grep and awk between the back ticks, and generate a file name, then ls using that filename* and write that data to a temp file.However, it executes the grep and awk before even SSH'ing and the command that goes to the server is simply an "ls /ops/pkg/ec/* > /tmp/tmp_file" since the grep and awk return nothing on the local machine.
