Analytics
Supplies a credential that is used for authentication.
Description
Called from the pbs_connect() IFL API to authenticate a connection with the PBS server. Designed to be called internally by PBS commands and components, to be used by our IFL layer to talk to the server. Can be run by any user.
It's a setuid root binary so it runs as the user who requests a connection to a server but it becomes root so that it can grab a privileged port.
Usage
/opt/pbs/sbin/pbs_iff [-t] <daemon host> <daemon port> <parent socket> <parent port>
/opt/pbs/sbin/pbs_iff --version
Options to pbs_iff
-t
Test mode; means tell me whether I can authenticate.
--version
Reports version and exits; can only be used alone.
Arguments to pbs_iff
host, port
Remote host and remote port
parent socket, parent port
The socket and port that they want pbs_iff to vouch for when it connects to the server.
Exit Status
Zero
If it was able to contact the server and extract a promise that the server will henceforth accept commands from the port and socket fd that you asked to vouch for (as long as they come from this host )
Non-zero
Otherwise (in practice 1, but not sure that's guaranteed).
