View 6 Replies View RelatedI want to use ssh to execute a command and to wait endlessly to log everything (in file) that comes as a stream of the connected server. But unfortunately, in the manual its written "If command is specified, it is executed on the remote host instead of a login shell"
So what happens is that when I specify my command:
ssh user@server "my_command"
It executed the command and the flow of execution returns to bash shell. So basically my session ends right after the command is executed. This happens only in case I specify command in the command line. If I login into ssh manually and then type "my_command", then the session doesn't end. I want the ssh not to exit, because after "my_command" executes, I want to capture everything in the session.
We are on our first Linux platform and I am trying to coordinate a distributed application backup across multiple machines. I am trying to write a script in which I would have used RSH to execute scripts on the other servers. We are no longer allowed to use rsh, and someone suggested ssh. I am using that instead of telnet, but I am not sure of the syntax"rsh server [-n] path/executable" is what I would have used, just not sure of the syntax for ssh
View 8 Replies View RelatedUp 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

and I want it to execute via ssh on a remote machine through a script. Therefor I need to escape it properly. Because of the massive use of regular expressions and commandline options, this is not an easy task. Is there any (online) utility that will escape that for bash use? I suppose pasting the code in vi and doing some search and replaces should do the trick. But for that I would need a list of characters to escape...
Do you know how to write a shell script that executes say 4 instances of the same program in different directories at the same time, and once ONE instance completes it executes a new instance of that program in a new directoryd so on, until 100 instances have been executed, each in their own directory

I've written a shell script that among other things, restarts network services. As such, I'd like to keep those who are remoting in via putty, etc. from executing the script. Is there a way to detect this and restrict running the script (by adding additional coding in the script) that disallows running it from unless you are logged in directly to the machine? It's written in bash.

View 2 Replies View RelatedHow do I obtain information about the running x-server from a remote shell session? I want to know things like resolution, color depth, etc. My xorg.conf is basically empty. The only thing I can think of doing is to read the Xorg.0.log file which seems inefficient.
I thought that 'xrandr' displayed some text output but that behavior has changed (?). It seems to require an X display. Is there another way? Something I could incorporate into a shell script? (This is Fedora but that shouldn't really matter)
I am trying to write a script to set the SGE job execution order. I named each job with 'job1', 'job2' and 'job3'. I want my script to do: When 'job1' execution is complete, 'job2' is executed; when both 'job1' and 'job2' are complete, 'job3' is executed.
First, I tried this following script and it worked well:
########
qsub -N job1 run1.sh # run1.sh includes "mv file_name1 file_name2"
qsub -N job2 -hold_jid job1 run2.sh # run2.sh includes "mv file_name2

I have never set-up a chroot-jailed environment before and I am afraid I need some help to do it well.To explain shortly what this is all about: I have a webserver to which users send python scripts to process various files that are stored on the server (the system is for Research purpose).Everyday a cron job starts the execution of the uploaded scripts via a command of this kind: /usr/bin/python script_file.pyAll of this is really insecure and I would like to create a jail in which I would copy the necessary files (uploaded scripts, files to process, python binary and dependencies).
I already looked at various utilities to create jails but none of them seemed up-to-date or were lacking solid documentation (ie. the links proposed in How can I run an untrusted python script)Could anyone guide me to a viable solution to my problem? like a working example of a script that creates a jail, put some files in it and executes a python script?
In bash shell, is there a simple way for me to monitor the time taken to run a script and output the time taken?
