Dear CCP4I2 experts,
I'm trying to submit remote jobs via SSH within CCP4i2. Unfortunately,
we use a non standard SSH port.
So far, I'm not able to add any option within the CCP4I2 interface. For
job submission, I need something to do like
'ssh -p XXXXX -Y ..... ccp4i-specific-command ...'.
Is there any chance to enter this '-p' SSH option within CCP4i2? I tried
already to define a "ssh command" via "Preferences".
But so far without any success.
==============
Not sure if this is applicable, but you can set an alias name
to be equivalent to a real host with a non-standard port.
Something like:
in ~/.ssh/config or /etc/ssh/ssh_config:
Host oswego
hostname sanpablo
hostkeyalias "[sanpablo]:8123"
port 8123
"hostkeyalias" refers to one key in ~/.ssh/known_hosts that looks like:
[sanpablo]:8101,[192.168.2.4]:8123 ecdsa-sha2-nist
I'm not sure if I entered that or it was made the first time I logged in and
said "yes".
So I or a program I'm running can issue "ssh oswego" and get connected to port
8123 on sanpablo without needing to enter a password.
========================================
I'm also wondering why there is a sshkey file option. If an user already
uses a ssh-key for a client/server connection, why is necessary to
re-input the key file again?
Any ssh between client and server should work from scratch ...
Any hints are highly appreciated,
Michael
