Trouble with ppp server on Redhat 7.1

[rdly]

I have been using ppp with a direct phone connection from one host to another for the last several months without problems. The ppp server was on a machine running Redhat 6.0, and the ppp client was on a Redhat 6.2 box. I replaced the client machine with a machine running Redhat 7.1, and it connected to the Redhat 6.0 ppp server fine. I then replaced the ppp server with a new machine running Redhat 7.1, and now the new ppp client running Redhat 7.1 cannot connect to the new ppp server running Redhat 7.1.

When the client calls the ppp server, the modems negotiate the carrier signals, and then hang up. I get the following messages in syslog.

--------------------------------------------------------------------
mgetty[1879]: data dev=ttyS5, pid=1879, caller='none', conn='38400', name='', cmd='/bin/login', user='ppp'

mgetty[7882]: failed dev=ttyS5, pid=7882, got signal 15, exiting
--------------------------------------------------------------------

The permissions on /usr/sbin/pppd for both client and server are -rwsr-xr-x
My options for the ppp client are
lock
hide-password
defaultroute
crtscts
modem
asyncmap 0

I use the following command on the client to connect to the server
/usr/sbin/pppd 192.168.1.1: connect '/usr/sbin/chat -v -f /root/.pppscript.server' defaultroute 115200 /dev/modem
(I'm using static addressing).

Does anyone know what I'm doing wrong with Redhat 7.1 that works with a Redhat 6.0 ppp server? I would be greatful for any assistance. -- Thanks.

pppd[1891]: using the noauth option requires root privilege

This is your problem, I am sure you have figured this much out so far.

I don't have much(if any) experience with ppp servers, but I do have a bit with the clients. So here is my suggestion:

Client side:
Go ahead and type chmod u+s /usr/sbin/pppd

now cd into /etc/ppp and check for an options file....check to make sure you don't have any pap options in there.

Server side:

Check inside your pap-secrets file and add a
"" * "" *
if it isn't already there...that should get you connected...I hope....if not come on back and we'll figure something else out for ya!

[paradox]

My fault...I didn't even pay attention that those options were from the options file....hmm....just try the chmod.....see what that does for you...

also on the client side in your options file add
noauth as one of the lines....your server doesn't need to authenticate itself to you....I doubt you have it set up that way anyways.

I found the problem. The client was logging in to the userid
ppp. Rh7.1 puts in the shell field of /etc/passwd (for the ppp
userid) a file called /usr/lib/linuxconf/lib/ppplogin. That is a bash
script that issues the pppd command with the command line option of
'noauth'. I took the noauth option out, and that solved the problem.
A similar script is used in RH6.0 and RH6.2, but the pppd command
doesn't have the noauth option.

Thanks for your help.

Great! I am glad you found the problem! Man, I wish the site had an OMP about setting up a PPP server, hint hint hint! Would you be interested? Please? ;D
