I tried to test it out with an rlogin from a remote host and never got a prompt; I checked the process from another terminal and it was using 95% CPU, and wasn't connected to a controlling tty! I tried telnetting there instead of rlogin, and got logged in okay, but I noticed errors from my init files such as "ioctl: operation not supported on socket", plus lots of "command not found". I inspected my environment variables, and they appeared to contain garbage, much like text that is output *by my .login*!! I removed my init files (both for bash AND csh), and rlogin still does the same thing. Telnet works okay, but from the errors my init files produced, it sounds like it's having a little trouble attaching the shell to a tty, plus a little trouble not sourcing my .login under a non-c-shell. Any ideas? --robert

This sounds similar to the error reported by pmy@vivaldi.acc.virginia.edu (Pete Yadlowsky) about using more under ksh via rlogin to a NeXT work station. The error is in rlogind, which fails to set a process group number for the shell it invokes. Apparently this doesn't bother csh, which must supply a process group number if none is set. Ksh doesn't, and probably the same is true for bash. I submitted my tentative fix to ksh-i-88f to David Korn and he answered with a better suggestion -- he had already come across the problem on an Alliant and had an #ifdef'd fix. That fix also works for NeXTStep 2.0. The fix involves reading the process group ID with getpgrp(0). If it is zero, it should be set to the process group ID that is obtained with the TIOCGPRGRP ioctl. Vic Abell <abe@mace.cc.purdue.edu>

Vic's solution has solved about half my problem so far. He also mentioned using TIOCSPGRP to set the tty process group and I added that [after I found the following :(]. I can get a shell but the errors from stty and output of ps indicate bash hasn't connected to a tty yet. So whatnext?
