- Well. 1. YES. I DID FIX THE MANUAL ROUTE ERROR IN MY AUTOEXEC.NET.
-
- 2. We've had damn' little problem here in the backwaters of Houston with
- automatic routing. Period. One exception: The overhead of frequent
- (hourly) updates really jams up a busy network, especially with a mix of ax25
- keyboard and tcp/ip users.
-
- 3. We've dropped down some from rip to rspf (some local folks have been
- hacking on it) and have had pretty reasonable reports. NOTE: That's yet
- another automatic routing scheme.
-
- 4. The problem we've had down this way is that there are 6-8 "permanent"
- tcp/ip nodes up all the time, and a bunch of transients. With hard routing,
- I've seen attempts to send mail, or connect for ftp sessions get lost when
- one or another transient, who'd advertised that he was gonna stay up all the
- time, dropped off-line to go chat with his buddy on 145.01 in unproto mode...
- And, no, this hasn't been infrequent.
-
- 5. In a real-net application, here at Johnson Space Center, we "enjoy" hard
- routes. +/- rip. Seems that it takes me no fewer than 8 hops to get out
- from here, via NASA Ames Research Center, for anything. Also, hard routing, on
- on my part to a more direct path doesn't work, because I have to go through
- the local sysco router, and it wanders around JSC and ARC for a while before
- deciding that bellcore.com isn't at one of the NASA centers... And that
- sysco is hard-routed.
-
- OK. I've said my piece. I know that there's a wide diversity of opinion on
- manual routes, and I've got my own prejudices.

-
- I try not to burden this group with a lot of postings but I feel that
- I need to amplify on my previous automatic vs. manual routing comment.
- I build IP based networks for a living and have a good deal of
- experience with different routing protocols and the advantages or
- disadvantages of routing protocols.
-
- For the most part automatic routing protocols are a big win in a
- network of any size. The only time manual routing is desirable over
- automatic routing is when the internetwork is limited to a single
- network.
-
- On the other hand some automatic routing protocols, most notably RIP,
- have a tendency to make things worse when the topology of the network
- is very dynamic. In most cases it is only one or two gateways that
- cause problems so the judicious use of manual routes and the rip
- refuse command makes things relatively palatable.
-
- I have no experience yet with RSPF but if memory serves me it is a
- shortest path first (SPF) link state based routing protocol. In that
- case it should be a big win over RIP (assuming that it is debugged and
- working properly) and as such should be a big win for amateur packet
- radio. Its transmissions should be smaller than RIP transmission too,
- a very significant issue with our bandwidth limited networks.
-
- Now lets look at it from the point of view of the neophyte. He/she is
- new to TCP/IP and possibly new to packet radio. A good automatic
- routing protocol allows his/her station to construct its own routing
- tables. He/she does not need to learn the intricacies of routing.
- Don't underestimate the power of simplicity. A good automatic routing
- protocol will greatly enhance the desirability of TCP/IP.

- Subject: Problems with compiling NOS
- To: TCP-GROUP@UCSD.EDU
-
- I 'm having trouble trying to compile the 0828 version of NOS. It seems
- that some header files aren't being included in the source and I constantly
- get undefined structures. I've had this problem with every version of NOS
- I've tryed to compile. Am I missing some crucial file that needs to be
- present? Is there anything that I need to set in TURBOC.CFG?
-
- Any help would be appreciated,

-
- I have been running a dialup SLIP link from my NOS machine
- at home to a Sun 3/60 workstation at VAL. A problem I have had
- concerns terminal emulation in TELNET. Does anyone here have
- a termcap entry that will allow me to use vi or whatever without
- having my screen switch to 40 column mode? :-)
