Query on SSH
Query on SSH
I did check the man ssh_config file -> points to maximun 10
or it depends on number of pseudo devices
And how about the "batch jobs running" using SSH
does this also require me to increase pseudo devices

You can query the number of ptys from the kernel with kmtune like this: (in 11iv2/v3 look for the kctune command)
# kmtune -q npty
Parameter Current Dyn Planned Module Version
===============================================================================
npty 60 - 60

Re: Query on SSH
Re: Query on SSH
That option is tied to a feature in SSH 4.x and up called "connection multiplexing," which allows you to start additional SSH sessions over an existing TCP connection, via the use of a socket:
http://www.debian-administration.org/articles/290
The "MaxSessions" option was introduced in OpenSSH 5.1 to allow more fine-grained administrative control of the multiplexing feature.
