If you're using NTP, then you'll want to run "ntpdate" to set the date
prior to starting the ntpd daemon.

I recently was helping someone with a flaky ISDN connection. Although it
still hasn't been completely resolved, it appears to be related to the fact
that the distance between the last repeater and the house is more than 18000
feet. What seemed odd is that large downloads worked fine, but uploads
would never work beyond a few 100Kbytes.
It may not be related to your problem, but it's probably worth checking.

This type of problem usually is caused by a router or firewall filtering
ICMP packets, which keep your system from determining the correct MTU size
(it should fall back to a size that works). It can be very frustrating,
since some sites will work and others won't. We has a similar problem with
an old SUN firewall. I had to use the same solution of forcing the MTU
size to be a size that worked with most sites.

I am running RH 5.2 on an IBM Thinkpad 310ED. Everything works great

megahertz 56K/10baseT combo card, and Linux can't find either one. Anyone
have any suggestions? TIA.

Subject: Routing and router redundancy
Date: Thu, 06 May 1999 12:09:42 GMT
I currently have a 10Mbs network and I am considering moving some of the
systems that generate the heaviest traffic to a 100Mbs segment.
I am considering doing this using Linux and ip forwarding to route packets
appropriately between the two segments.
i.e.
eth0 - 10Mbs segment - 192.168.255.0
eth1 - 100Mbs segment - 192.168.254.0
However, in such a setup the router has to be extremely reliable, if the
router should fail (hardware failure, naturally) then the two subnetworks
would become invisible to each other, this is not an acceptable solution.
How could I implement a secondary (backup) router into such a scheme to allow
some redundancy and how would I set up and configure such a system.
Thanks for any suggestions

Subject: Serial cables or Cerial for breakfast...
Date: Thu, 06 May 1999 13:27:43 GMT
Hi Everyone:
Here I am with my bowl of O's & milk and I'm thinking, "I
sure would like to get that Livingston PM-11 running".
Here is my question:
How do I connect from a Linux box DB25 male serial port to
my Livingston PM-11 DB25 female serial port to start setting
it up.
Do I use a:
DB25 pin M-F serial cable,
DB25 pin M-F modem cable,
DB25 pin M-F null-modem cable,
None of the above?
The PM-11 appears to boot up, (can hear floppy flopping
about), but I have no way of even beginning to talk to it
until I can login and I can't do that until I figure out HOW
to talk to it.
This is by no means an emergency, I just happened to pick up
this historical piece of gear on eBay for a song and I would
like to get it attached to my home tcp/ip network and play.
I have read most everything about the PM-11 (PM-2 manual)
including the upgrade stuff so I am on the lookout for the
additional DRAM chips (can anybody help with that) that will
allow me to upgrade the software but that comes next!
Thanks everyone.
Best regards,
Brian

I believe it is a null-modem cable. I'm sure it is not a custom cable.

I believe this is known as multilink, or shotgun, ppp. Read up on EQL PPP in

If all Brian wants it to run two networks other the same piece of wire
all he needs is a route command that tells the kernel both networks
can be reached via the same interface with no gateway.
route add -net <network> <interface>
does this. (Been there and done that for a machine that needed the extra
route to see it's default gateway).

It all depends on if you want to compile PPP support into the kernel or as
a module. The only difference between either option is what you select
for the network options. Actually which distribution are you using?
If during 'make menuconfig' (or 'make xconfig') you selected PPP as a
module,
then you need to do the following after you finished the 'make menuconfig'
session and have saved the configuration:-
/usr/src/linux# make modules
/usr/src/linux# make modules_install
That should compile the modules and then install 'em for you.
(_IF_ the modules aren't installed : to check, type lsmod at the
prompt. If you see PPP in the list, then you have the module
installed. Otherwise, you just type 'insmod ppp' and it will
load. If it doesn't, it means the PPP module wasn't installed/
compiled properly.)
So when you reboot(not sure if this is really necessary, unless you've
compiled a new config for the kernel), a 'dmesg' should result in
a screen dump of the boot up process, in which there should be
some lines displaying the "PPP:..."
If you elected to compile the PPP support into the kernel, then you'd
have to recompile the kernel and then, if need be, re-run lilo and then
reboot. You should then get the PPP lines.
I hope this helps
