Top Forums Shell Programming and Scripting ssh can't back from remote host during script execution Post 302389273 by bzylg on Saturday 23rd of January 2010 08:30:08 PM

Hi all, I pretty much resolved this, the cause of this problem is:

SSH connects stdin, stdout and stderr of the remote shell to your local terminal, so you can interact with the command that's running on the remote side.

As a side effect, it will keep running until these connections have been closed, which happens only when the remote command and all its children (!) have terminated (because the children, which is what "&" starts, inherit std* from their parent process and keep it open).

So I modify my code to wrap those 4 cmds in script and run it like this
Code:
ssh <user>@<host> "<wrapped_script> >& Worklog.log"

which redirect stdout and stderr to a file, I am using csh. Thank you for your help.

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 (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). 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) SEE ALSO
