Full Discussion: Testing ssh connection from KSH script
Top Forums Shell Programming and Scripting Testing ssh connection from KSH script Post 73301 by bakunin on Tuesday 31st of May 2005 04:40:09 AM

The problem (i have the same one, btw.) is more difficult than that: it is possible to make sure the remote server is up and running, but I don't know of a simple way to make sure the keys for a secure connection are exchanged.

ssh <somewhere> -c '<command>'

will work fine if the keys are exchanged, but will hang if they are not. In this case ssh (scp, ...) will present an interactive screen asking to enter the password - which will hang the script, since it will never answer to that.

       sieveshell --help

DESCRIPTION

       sieveshell allows users to manipulate their scripts on a remote server.	It works via MANAGESIEVE, a work in progress.

       The following commands are recognized:

	   list list scripts on server.

	   put <filename> upload script to server.

	   get <name> [<filename>] get script. if no filename display to stdout

	   delete <name> delete script.

	   activate <name> activate script.

	   deactivate deactivate all scripts.

OPTIONS

       -u user, --user=user
	   The authorization name to request; by default, derived from the authentication credentials.

       -a authname, --authname=authname
	   The user to use for authentication (defaults to current user).

       -r realm, --realm=realm
	   The realm to attempt authentication in.

       -e script, --exec=script
	   Instead of working interactively, run commands from script, and exit when done.
