I've run up against the following bug under Solaris2.4:
When I rlogin to a Solaris2 host running klogind, I get the message:
Warning: no access to tty; thus no job control in this shell...
This message comes from /bin/csh. Running a trace shows that just
before the message is output, a TIOCGPGRP ioctol is failing:
ioctl(18, TCGETA, 0xEFFFFC5C) = 0
ioctl(18, TIOCGPGRP, 0x00047A88) Err#25 ENOTTY
ioctl(17, TIOCLGET, 0xEFFFFB5C) = 0
write(17, " W a r n i n g : n o ".., 64) = 64
The termio man page says:
ENOTTY The file associated with fildes is not a terminal.
I get a similar message with tcsh-6.05, where tcgetpgrp() is failing.
I get this message with Cygnus' CNS code, and with a local KerberosIV
installation. My guess is that this is some sort of nasty Solaris
botch.
Interestingly, the CNS telnetd works fine, I have job control and
everything. Both telnetd and klogind are using the same login.krb
binary.
Any ideas?
BTW - I had a wierd failure with login.krb where rlogin was just
immediately exiting:
cxh@foo.EECS.Berkeley.EDU> /usr/kerberos/bin/rlogin bar
Last login: Tue Jun 20 17:37:16 from bif.eecs.berk
rlogin: connection closed.
cxh@fooa.EECS.Berkeley.EDU>
After poking around with the CNS login.kerb, it looks login.krb was
calling initgroups() which was failing. I hacked login.c to use the
initgroups() contained there for SCO, and now I can at least use
rlogin. I'm not sure what the cause of the problem was . . .
