[Nagios-users] check_by_ssh from nagios user

[Mario Garcia]

Hello
i want to monitor a bluecoat reporter with check_by_ssh as nrpe or snmp are
not available.

when i loggin from nagios user using simple ssh I can login
when i execute check_by_ssh from root user and execute a command it does
work

when i execute check_by_ssh from the nagios user on the nagios server it
does not work.. the public key is not taken into account as it request the
password despite the fact that i add -i option to check_by_ssh..

do you have an idea what could this be? is it the bluecoat reporter which
is refusing check_by_ssh, why does not refuse when i just use ssh ..

note I am conneciting from nagios user on nagios server to root user on
bluecoat reporter..maybe i should try to login to nagios user on the remote
system?

i am out of ideas

thanks

Can you do an ssh from nagios server as nagios user to the blue host server
without password with -i option
ssh -i .ssh/<key> <bluehost>

If the bluecoat is configured to allow root login, then make sure that the nagios machine's nagios user's public key is in the bluecoat machine's root user's authorized_keys file. Otherwise just log in as the nagios user. For security reasons it's most likely a better idea to work as a noon-root user anyway.

Hello

the problem does not occur when logging with simple nagios user
it only occurs when trying with check_by_ssh.

edit:
I managed to get it to work.. but i do not really know which solution
worked..

i edited sshd_onfig and disabled PAM
on the bluecoat I created a nagios users, gave it a home dir and assigned
it a password... restarted the ssh daemon, logged off and logged back in..

does check_by_ssh triggers some PAM authentication requirements?

thank you for your support.
