Issue with nohup command

Hi everyone,
I am starting a nohup from a script (via scheduling system) as follows:
ssh user@server "nohup command & ; exit 0"
This command is not returning the command prompt untless I press "ENTER". This is causing the schedule to hang at this job and not continue with the rest of the jobs. It seems that "exit 0" command is not taking effect. Could you help please.

Thanks.

Hi.

What about:

Code:
ssh user@server "command" &

Is it neccessary to use nohup at all?

What if the command takes hours? What if, during those hours, you have an internet service outage, causing the connection to break and the command to be killed? What if its generating tons of log spamming or something? There's good reasons to want to background the remote process instead of the local ssh connection.

What shell is being used here? If you're using bash, you might want to add a 'disown' command after the &.

Not sure I follow you.

The process on the remote server won't die if the server you started it from does. What is the parent process of the remote command? A process ID on the local server you started it from? I don't think so.
