When I use PPP over a serial line between a sun4/330 and a sun 4/20 both running sunOS 4.1, I get the following error message: ppp: setsid(): Not owner. and the connection over the modem hangs up. I haven't been able to figure out what I'm not the owner of. Is there some discussion somewhere which will explain about setsid(2)? The man page is too terse for me to understand. Here is the details of the set up I'm using. I have the PPP from tut.cis.ohio-state.edu from pub/ppp-sparc4.1.tar.Z. I have an account on the work machine (sun4/330) called Pmclay Pmclay:79SXQ7UAnIvZY:4:8:PPP start Robert McLay:/tmp:/usr/local/etc/pppstart Here is what pppstart looks like: #!/bin/sh /usr/bin/mesg n stty -tostop hupcl exec /usr/local/etc/ppp -p 128.83.152.29: Heres what ppp is set to: -rwsr-xr-x 1 root uucp 147456 Jan 10 12:59 /usr/local/etc/ppp* Here is exactly what happens when I try to login by hand.

I made those changes, and forwarded them to Karl Fox, they work quite fine for me. When you run ppp by hand, you will not be able to set the session id. This is because your login tty is not a controlling terminal etc. Check if the ppp executable is setuid root, so as to be able to manipulate the controlling terminal etc. I am puzzled because the message seems to be one generated by a perror() statement. The ppp-sparc4.1.tar.Z code does not have a perror() statement associated with the setsid() code. Can you forward the relevant sections of code so I can take a look at it?

When ppp is compiled to use setsid() it should not be exec-ed. "Not Owner" is this particular case apparently means "Already Owner", and why it is an error is beyond my ken, but removing the 'exec' fixes it. -- Guy Streeter, streeter@ingr.com ...uunet!ingr!b11!guy!guy
