cssh trough ssh-gateway

[opsoli]

I´d like to use cssh trough a ssh-gateway. To do this, i have to call one gateway-session for every server i´d like to use and give this session the command to open the server session.

For example:

cssh user@sshgw:"ssh user@server1" user@sshgw:"ssh user@server2" ....

I know it doesn´t work by now this way. But is there any way to do it? Or is it possible to add this feature in one of the next releases?

Hi,

take a look on chainssh
https://sourceforge.net/projects/chainssh
chainssh is a shell script to smplify the ssh login via multiple sshgateways/firewallgateaways. e.g. connect from homehost via sshgateway to a clusternode with one command.

Hi bobsf,

thanks for your reply, but I need a tool for an interactive shell on many servers over ssh-Gateway. With cainssh I can´t do this.

Thanks

Hi opsoli,

shur it shut work, cssh with cainssh! (i use it my self)

config chainssh to work with the diferent hosts (via the ssh-gateway)
and then replace in the .csshrc
the
ssh=/usr/bin/ssh
with
ssh=chainssh.sh

so youre use cssh for the conect to "many servers"
and let handel cainssh the connetct form you host via the ssh-gateway (or many ssh-gateways) to the taget server.

Hi bobsf,

sorry, but I can´t figure out the configuration of chainssh. I tryed some different configs, but it doesn´t worked for.  After all, chainssh showed me the way to do what I want to do. I just changed in .csshrc

ssh=/usr/bin/ssh
to
ssh=/home/me/sshgw

and made a little script called "sshgw":

ssh -x -o ConnectTimeout=10 -C me@sshgateway -t ssh -Cx $2@$3

and it works fine for me.
