How to starting process as daemon using ssh command?
Hello,
I need to run a command on remote Linux using the ssh command from my local machine. I am able to execute the command on remote machine using ssh but it's behaving strangely.
The command is supposed to start a daemon process on remote linux box and the control should return back to me but strangely this does not happen. The command works properly (i.e. starts the daemon process) when I ssh into remote linux box and type the command on console.
Here is how I give command on remote linux machine after sshing into the box.
$ /usr/local/bin/fatality.sh --email=nitins.shukla@gmail.com --log_dir=/tmp/fatality &
[1] 23274
$
This works fine and the process runs as daemon in background.
But when I try to run this command on same Linux box from my local machine, the process does not start as daemon and runs in background. Here's how I give the command from my linux machine
$ ssh root@remotelinux "/usr/local/bin/fatality.sh --email=nitins.shukla@gmail.com --log_dir=/tmp/fatality \"&\""
The control does not return back to me. Logging on the remote linux box I find that the process is running but not as daemon process in background.
Can anyone help how I should pass the command to ssh start the process as daemon process so that the control returns back to me.
Note both the time I am using same user account i.e. root to log on remote linux machine.
Any help is deeply appreciated.
Thank n Regards,
Nitin

How do I start a background process and save the process id to a file on my system. For example %wait 5 & will execute and print the process id. I can't figure out how to get it to a file. I've tried: > filename 0>filename 1>filename.
Any assistance is most appreciated.

Hi
We are running SCO ver 5. Recently the cron daemon stopped running on its own. How do I find out why? How do I restart/stop it?
I typed cron but it didn't work. Will rebooting it do the trick or can I manually start and stop the cron daemon?

ssh-copy-id
SSH-COPY-ID(1) General Commands Manual SSH-COPY-ID(1)
NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys
SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine
DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine and append the indicated identity file to that machine's ~/.ssh/autho-
rized_keys file.
If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your
ssh-agent. Otherwise, if this:
ssh-add -L
provides any output, it uses that in preference to the identity file.
If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin-
gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory,
if necessary.)
NOTES
This program does not modify the permissions of any pre-existing files or directories. Therefore, if the remote sshd has StrictModes set in
its configuration, then the user's home, ~/.ssh folder, and ~/.ssh/authorized_keys file may need to have group writability disabled manu-
ally, e.g. via
chmod go-w ~ ~/.ssh ~/.ssh/authorized_keys
on the remote machine.
