Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: questions-owner@freebsd.org Precedence: bulk Hey all - sorry to post to so many lists, but I'm having some _very_strange_ problems with my SLIP dialup users ever since I upgraded our box from 1.1.5.1. Config: ASUS SP3G, 40mb RAM, NCR SCSI, 2.1gigs (Quantum Empire), ATI Mach32 video, BOCA 2016 16port serial board. Machine's primary function is terminal service, name service, WWW service. No problems with 1.1.5.1 on this box. Have 6 14.4 modems and 2 28.8 modems on the Bocaboard. Here are the symptoms: 1. Dialup (non SLIP but on same modem lines as SLIP users) still works perfectly. 2. SLIP works fine for some users and doesn't for others. There is _no_ connection whatsoever between configs for people that it works for and for people that it doesn't. Some users dial in, log in with their slip login id (which has /usr/sbin/sliplogin as their login shell) and all is great. Some users dial in, login as their SLIP id, SLIP _appears_ to be up, but they can't see the net, and the net can't see them (ping). Again, there is nothing I can tell that is different for the people that it works for and the people that it doesn't. One of the users for whom it doesn't work is logged in right now, /var/run/utmp tells me they're logged in -"w" reports they're logged in and their login shell is sliplogin - e.g. 6:11PM up 5:33, 4 users, load averages: 0.00, 0.08, 0.07 USER TTY FROM LOGIN@ IDLE WHAT slipuser d2 - 5:52PM 19 -sliplogin (sliplogin) adhir p0 machine 5:42PM - w -n When I ping that user's machine, I get the following: [bigdipper:~] ping machine PING machine (198.6.14.52): 56 data bytes ping: sendto: Network dropped connection on reset ping: wrote newsusa.com 64 chars, ret=-1 Strangely enough, for a short while after this user first logged in, I couldn't ping them (I got the above error), but I could telnet to their machine on port 25 (they're running an SMTP mailer). VERY strange. A few minutes later I could neither ping nor telnet.
