Greetings Can anyone assist me with implementing a restricted bash shell. Currently I am testing a restricted bash shell using the bash 2.01 with the -r option. After creating 64 processes I get a "fork : Resource temporary unavailable" error and cannot execute any command. I have used this error to gain access to an unrestricted bash shell. Is there any way I can prevent anyone from logging in when a "resource temporary unavailable" error occurs ? The kernel is currently 2.2.5 , the restricted shell uses ssh version 1.26 to log into the rest of the network and the box will act as a firewall of sorts. I cannot recompile the kernel as the box was really stripped down by my predecessor.
