setting up pppd dial-in on linux

setting up pppd dial-in on linux

[Jeff V. Merkey]

Anyone out there a whiz at setting up a pppd dialin server?  I am 
trying to put together an RPM for pppd dialin configurations
that will support default Windows NT and Linux dial in clients
without requiring the poor user to learn bash scripting, chat 
scripting, mgetty and inittab configuration, etc.  The steps
in setting this up are about as easy as going on a U.N. relief
mission to equatorial Africa, and most customers who are 
"mere mortals" would give up about an hour into it.

I am seeing massive problems with pppd dial-in and IP/IPX 
routing with problems that range from constant Oops, to 
the bug infested pppd daemon failing valid MD5 chap 
authentication.  The HOW-TO's and man pages provide 
wonderful commentary on all the things about pppd 
that don't work, but it's not too helpful on getting
it to work reliably.  An NT dial-in server takes about
5 minutes to configure on W2K.  Linux takes about 2 days, and 
won't stay up reliably.  

Who out there is an expert on Linux pppd that would like
to help put together some easy configs for standard 
dial-in scenarios?

Thanks

Jeff

Red Hat's ppp client setup is about a 90 second job

hmm, an awful lot of ISPs use Linux dialup servers...

I set up a linux ppp server back in 1996 - things might have
changed, but it seemed fairly straightforward at the time -

can't imagine it's gotten worse since then...

Crunch time for me right now, finals coming right up...

I'll bet there's quite a few ISP-savvy admins who could
lend a hand though -

   You are not alone. And the problem gets even worse when you 
have to deal with ISDN devices. In my company´s data room we 
have all Linux servers running 365 days a year (minus upgrade 
time) and in one corner a lonely Windows NT Server 3.0 with 5 
Client Access Licenses working as a RAS server for 2 Diva Server 
BRI cards (4 analog/digital channels) plus one analog modem. 
Time to set it up? Half an hour counting NT installation. Time i lost 
investigating and trying different configurations, dealing with 
contradictory documentation, chat scripts, different ipppd versions, 
and authentication failures? 2 days. At Ieast i cant complain about 
pppd oops, as you do, the pppd in RH6.2 seemed solid. The 
document of reference that seemed more interesting to me at the 
time was http://www.swcp.com/~jgentry/pers.html  , have a look 
please.

Pedro

Jeff,
  I am also VERY interested in this, particularly on getting modems to work
with Linux at all.  I'm not reading the list right now, but I'd appreciate
any feedback you can throw my way on this.   Esp. if you DO get it setup and
working.  It sure would be nice to see Linux FINALLY support more modems out
there.  Hell, my Internal USR ISA modem is not even supported, but FreeBSD
had had support for it for a long time now.  :-(  Please let me know what
you find out, and I'm VERY interested in your RPM - hope there will be a
straight tarball for us Slackware Dinosaurs too.  :-)

Scott

I am using theirs as a base.   Setup's not the issue.  It's the 
chap MD5 authentication for NT clients and the constant 
crashing that's troublesome.  I have it working, just not
with NT clients.

Thank's anyway.  I'll keep working on the bugs.

Thanks.  We need to get the Linux stuff to the same point.  From 
our analysis, it's the only weak feature left -- Linux either 
matches or surpasses NT in every other area now except this one.

I'll post ot at vger.timpanogas.org with the Ute-NWFS distribution.  It 
will be freely downloadable.  Having plug and play NT dial-in support 
would be very nice.  SuSe has a pretty nice setup, but we have as many,
if not more problems with their's vs. RedHat and ours.

Probably this little patch will help you. I had similar problems with
Windows 95 and encryption
enabled.
