Top Forums Shell Programming and Scripting Need some help in bash scripting with ssh Post 302640167 by methyl on Monday 14th of May 2012 08:24:17 AM

Any one of the commands containing asterisks could expand to a line which is too long for the remote system's shell or produce some invalid syntax. Maybe try a diagnosic echo of each command to see whether one or more of them is failing on that particular remote system.

As a minimum, try placing a diagnostic echo after each ssh command in the master script so you can work out which command is failing on that particular server.

Are all the remote servers running the same Operating System as the master server?

Personally I would not issue one ssh per command. I would write a proper robust script and place it on each remote system.

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
ssh(1), ssh-agent(1), sshd(8) OpenSSH 14 November 1999 SSH-COPY-ID(1)
