Bash Version: 2.05a
Patch Level: 0
Release Status: release

Description:
        bash advertizes that it tries to source ~/.bashrc when run by
        sshd or rshd. This ought to work as well for kshd (kerberos
        version of rshd), but it doesn't. The reason seems to be that
        kshd runs the shell on pipes instead of simply execing it with
        copies of stdin and stdout so isnetconn() in shell.c doesn't
        detect the network connection thus hidden. (Are there rshd's
        that do this too?) kshd sets some special environment variables
        and sets TERM=network so I used this to fix the problem.
