SEMiSLUG Notes
10 September 1998
Question & Answer Sessions
- What does the 801 dailer do in uucp?
- Loke the 212, it's an AT&T dailer unit. Some people are still using
them. Mike Wayne knows more about this, if he can find his notes.
- How do you set the per-user max processes limit under AIX (4.2)?
- No good ideas. SMIT is a cruel practical joke.
- Where are the mailings?
- Send majordomo@semislug.mi.org the following message:
or
subscribe semislug-announce
and join the fray. Or send mail to Gabe and ask for the instructions.
- What about the website?
- Go peek at http://www.semislug.mi.org/ and see!
- Sparq 5 and Solaris 2.5.1 with much memory (256 ram, 512 swap), but
emacs swaps muchly. What's up?
- Something aint write. Start looking at 'top' and see if anything
odd rears its head. Something has got to be sucking up heaps of
memory.
- Has anyone seen S.u.S.E. 5.3 Linux on the shelves?
- Nope. Lots of 5.2 disks out there, though.
- Has anyone made a bootable CD-ROM under any BSD?
- If you're willing to swap CD's part way through. There are
Linux sites with docs on how to do this -- it may translate.
No one here seems to know the spell. Let Mike Wayne know if
you know it.
- Free PPP that will work with PAP under Solaris 2.6?
- A 386 will make a decent router. Unfortunately, Becki doesn't
have this option at the moment. There's some form of Morningstar
PPP on the net somewhere that can be picked up free.
- Has anyone hacked a variable stack into sendmail?
- Write to Eric Allman; offer him wine.
"Didn't someone do Towers of Hanoi in sendmail?" -- EMV
- How is the Solaris ping insecure?
- You could overflow the buffer and push operations onto the stack.
Check the bug-tracks archive.
- Is there an automated 4.1.4 SunOS install with all of the Y2K patches?
- Greg Cronau may have some 4.1.3 scripts that may help.
- CMD640 IDE controller gives Linux fits. Any patches out there? It's
in an Acer.
- Motherboards are $100; cases are $35.
- Anyone notices any marked difference in ascii vs. binary ftp?
- Yes. Sometimes you can speed up an ftp session by pinging the
ftp site in another window. Ftp is a poor benchmark.
- Do we have a ITI (or other) host for next weekend?
- Yvars said he'll do it.
- Jobs? Wanted? Available?
- Low level driver work at Seagate, telecommuting. Talk to Troy.
ERIM has two software engineering possitions available. Talk to Becki.
Msen is looking for entry-level tech support. Troy (city) is prefered,
but Ann Arbor is a possibility. Talk to Mike Wayne.
Worldcom is looking for system admins. Talk to Steve Simmons.

Presentation
"Voice over IP" by Munther L. Antoun (antoun@cisco.com)
Why?
Customers want it.
If the ISP or WAN can provide the bandwidth, the opportunity is there.
L3/L2 Transport Characteristics
Digital Signal Processors have become smaller and less expensive. The
capability for VoIP has been around for years, but the practicality
wasn't there. Now it's here. It's still a bit rough, in terms of quality,
but if people are willing to accept the quality, there's a great potential
for cost savings.
[... some discussion of quality of service ensues...]
Delay Variation -- "Jitter"
Delay is more critical in some places than others. SNA has timing
problems. Other times, people don't care so much about QoS, as long
as they can get messages across.
Neat stuff. Expect to see more of it. Expect it to get better.
Let's get Cisco back to talk about other interesting things.
Rumor & Inuendo
- Yes, www.semislug.mi.org is up and updated.
- The Northwest Airline strike is over.
- Who _didn't_ Microsoft subpaena?
- One of the large security software vendors may have the source
code to a unix-based OS. They can detect things that couldn't
be detected without looking at the source code.
- The web-nanny software won't be able to access the U.S. House
web site once the Starr report is posted.
