I suggest we keep this thread open and fill it with additional information until the problem gets the attention it needs. I'm not a programmer, much less a kernel hacker, so I can only voice frustration with the situation. Some additional information gleened from observations: First, the original problem as I originally mentioned it: We are running slip to our internet provider, and intermittantly experience telnet lockups during logins. The system either 1) refuses connections 2) accepts the connection, but just sits 3) provides a login prompt, takes input, and never gives the password prompt (ususally creating a login zombie in the process). Additional information/trends noticed: If the lockup occurs, allowing the telnet session with the locked connection to sit while starting another is *always* successful. It *appears* that a particular ttyp# gets buggered somehow, and forcing the system to seek another one will get you in. I.E. We've had *tons* of complaints about ttyp1 and ttyp4 lately (although I've seen the problem also on ttyp3 in the past). In the event 'refused connections' are the symptom to those telnetting in over the SLIP connection, logging in by adding an x-term *on the console* that grabs the offending ttyp port will suddenly allow SLIP telnet accesses. I thought that once a user was successfully logged in, everything was fine. However, I have had complaints of 'gradual slowing' or 'gradual slowing then locking' from a couple of users. I intiially dismissed this as 'net problems', but after hearing Michael Haardt's comment, I'm beginning to think that's what's happening to us as well. I also suspect that other 'general' user complaints about our 'slowness' at times would turn out to be the same thing as well. I have been experimenting with MTU sizes with ifconfig, but have no feel for whether or not this has any effect. I *have* noticed that MTU gets reset to 1500 by *something* some random time after I've changed it (note this is without system reboots). Here's a sample of what we have: yiffy:~# ifconfig lo Link encap Local Loopback inet addr 127.0.0.1 Bcast 127.255.255.255 Mask 255.255.255.0 UP BROADCAST LOOPBACK RUNNING MTU 2000 Metric 0 RX packets 0 errors 0 dropped 0 overrun 0 TX packets 39754 errors 7 dropped 0 overrun 0 sl0 Link encap AMPR AX.25 HWaddr inet addr 198.30.162.1 P-t-P 199.18.108.11 Mask 255.255.255.0 UP POINTOPOINT RUNNING MTU 1500 Metric 0 RX packets 1583360 errors 0 dropped 0 overrun 0 TX packets 1995660 errors 0 dropped 16514 overrun 0 eth0 Link encap 10Mbps Ethernet HWaddr 00:20:AF:16:4C:3E inet addr 198.30.162.1 Bcast 198.30.162.255 Mask 255.255.255.0 UP BROADCAST RUNNING MTU 1500 Metric 0 RX packets 293959 errors 0 dropped 0 overrun 0 TX packets 285447 errors 0 dropped 0 overrun 0 Note that a few moments prior to running this, I had set sl0 MTU to 2000, and confirmed that the value was accepted. Now it is 1500 again without any action on my part. One last observartion. When we first started with kernel 0.99.15, telnet sessions were locking up when large amounts of data was to be sent *out*. That is, if someone did a large directory listing or other function with lots of output, their session would hang. The send buffer information in 'netstat' showed several thousand characters waiting to be sent, and the session would be effectively frozen. This problem was acknoledged by others at the time, but as in this case, no answers were provided. The problem went away when moving to the 1.0 kernel. So *something* was done bye *someone* for that one. I'm new to all this, and don't know all the avenues to pursue. I'd appreciate any help in getting this problem hilighted and information flowing to the *someone* who understands how the net interfaces really work and who can really and *finally* *fix* it! How do we proceed?

We have setup a guest account which by default runs lynx when a user telnets into our machine and logs in as guest. A new user who has never used lynx before gets confused. We have received mail from people who said they couldn't use it. The guest account automatically recognizes the terminal type of user logging in. If for some reason it can't, it prompts the user for that information. I do not suspect that the guest account is not detecting the terminal type correctly, since I see the same behaviour when I run lynx on my machine under xterm, vt100 etc. on this machine. If you have telnet access, open a telnet session to sparco.com and login as guest to see what I mean. Any help will be greatly appreciated.

Anyway, I need a good unix development [snip] Ok, here's the answer: REAL TIME is _main_ concern: QNX4, not LINUX TCP/IP, XR6, GCC, Lots of GNU stuff: LINUX, not QNX4 Here we are using both QNX4 and LINUX. Linux does a much better, easier, and a helluva lot cheaper job on TCP/IP, X, GCC, ... than QNX. QNX, however, is _far_ better at fast context switching for real-time apps. If you don't have a real time app, forget about QNX. QNX is not UNIX. Linux is much closer to UNIX. BSD/386 I gave up on 3 years back. It might be pretty nice, but I don't have recent experience. I say do the right thing... SUN: real unix and real-time. -- zaphod@teleport.COM ------------------------------ From: adam@yggdrasil.com (Adam J.

Date: 1 Oct 1994 02:22:48 GMT Everyone, There are only a few people who can be more demanding than me and to be honest, I'm a real pain sometimes about support and love to complain. I am not affiliated with Marvin Wu and SWT in any way except as a repeat customer. Marvin has helped me with some questions that, looking back were pretty stupid, with patience and care. He has ALWAYS bent over backwards to help me with hardware problems and has done more than any vendor has done for me in YEARS. Really. It is impossible to make 100 percent of your customers happy 100 percent of the time. My customer service skills are at the bottom of the pit. I picked SWT out of about 10 'glossy' ads in Computer Shopper and I'm sure that NONE of them, based on my limited patience ( very low tolerance for pain ), would come close to Marvin's sincere attempt to be honest in a very dishonest world. Please don't flood my mailbox with those questions..... "what system did you get", just drop SWT an e-mail and ask Marvin, he will try his best. In todays world, that goes a long way with me.
