There may be several problems and you are the only one to find out, because you have posted no error messages or other diagnostic output. Take the following as pointers:
- maybe for some commands a terminal is required or wrongly allocated. Search the man pages of ssh for "-n" and/or "-q" and decide if this applies to your situation. In any case you might want to include the -o BatchMode = yes into your ssh-command.
- try an interactive session with the machine where it doesn't work: if the keys are not exchanged and/or if the system is not in your known_hosts file you might experience problems. To avoid the "The authenticity of ... Are you sure you want to continue connecting (yes/no)?"-message you need to set "StrictHostKeyChecking" to "no" in the options.
- specify an explicit user to use in the ssh-call:
will connect as "user" to "remote.host" and then issue "command" as this user. Otherwise you are relying on the user who issed the command on the local host, which may or may not be what you want.
- you use a variable "JBOSS_HOME" without defining it in the script. It might be that you are not running the same initialisation scripts if your session is not interactive. In general it is better to set explicitly in a script what you use and never use relative pathes at all.
There are most probably several more possibilities of what could have gone wrong, but this is all guessing, so the above list is incomplete in nature.

Hello all,
I have a relatively simple script I wrote to generate a count of errors broken down. What I would like to do is execute this script from another server so that I don't actually have to log in to the server to run the check.
The script on what we'll call "Server A" is:

the ssh calling convention:
ssh <server>
If I put commands in the section, ssh will execute them immediately after logging in and return to local shell. I want to stay in the remote shell after executing these commands. How can I achieve this?
Thanks for all. (1 Reply)

ssh-keysign
ssh-keysign(1M)ssh-keysign(1M)NAME
ssh-keysign - ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication
with SSH protocol version 2. This signature is of data that includes, among other items, the name of the client host and the name of the
client user.
ssh-keysign is disabled by default and can be enabled only in the global client configuration file /etc/ssh/ssh_config by setting Host-
basedAuthentication to yes.
ssh-keysign is not intended to be invoked by the user, but from ssh. See ssh(1) and sshd(1M) for more information about host-based authen-
tication.
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, readable
only by root, and not accessible to others. Because they are readable only by root, ssh-keysign must be set-uid root if host-based
authentication is used.
ssh-keysign will not sign host-based authentication data under the following conditions:
o If the HostbasedAuthentication client configuration parameter is not set to yes in /etc/ssh/ssh_config. This setting cannot be overri-
den in users' ~/.ssh/ssh_config files.
o If the client hostname and username in /etc/ssh/ssh_config do not match the canonical hostname of the client where ssh-keysign is
invoked and the name of the user invoking ssh-keysign.
In spite of ssh-keysign's restrictions on the contents of the host-based authentication data, there remains the ability of users to use it
as an avenue for obtaining the client's private host keys. For this reason host-based authentication is turned off by default.
