network (ip) problems with redhat

Post by ChunkB » Sun, 25 Jun 2000 04:00:00



        I've just installed redhat 6.0 on a multi.  I ran 5.2 without
a hitch -- it was serving on the internet and things were good.  but,
that was about a year ago, and the machine's been sitting around
collecting dust.  now with 6.1 I get this crazy error when pinging the
LOOPBACK address (127.0.0.1):

PING 127.0.0.1 (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=1.8 ms
wrong data byte #8 should be 0x8 but was 0xee
        c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 21

        2c 2d 2e 2f 0 0 0 0 0 0 0 0 0 0 0 0

--- 127.0.0.1 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 1.8/1.8/1.8 ms

needless to say my ethernet is in similiar condition.  HELP!!! (no I
didn't check to see if 5.2 was still working before I installed 6.0)
I already re-installed 6.0 a couple of times with different options
(my first install was bare bones, I thought maybe I scrwed up with
some dependencies, so I re-installed with the default options.)

thanks!

The ping and traceroute programs that come with RedHat 6.0 are buggy on
Alpha platform.

See http://www.redhat.com/support/errata/RHEA1999019_01.html for the
explanation of the problem.

Fix with: ftp://updates.redhat.com/6.0/alpha/
        netkit-base-0.10-31.alpha.rpm
        traceroute-1.4a5-16.alpha.rpm

network (ip) problems with redhat

        AHA!!!  That fixed it.  Thank you both for the advice, it did
the trick.  Now it turns out I have ANOTHER network problem.
        When I went to the RedHat site to get the new rpm's, I also
downloaded the stable versions of other packages that were buggy...
specifically the kernel.  After I fixed my last problem, everything
was fine.  I then installed the 2.2.16 kernel (I left all the files
for the 2.2.5 kernel that came with RH 6.0).  Now when I reboot with
that kernel, I get errors  in my /var/log/messages that say "Eth0: No
link beat found.", meaning there's no ethernet link.  TRUST ME, the
ethernet is fine.  I can reboot into the old kernel (2.2.5) and it
works, then boot into 2.2.16 and it doesn't work.  (And yes, there's a
link light on the hub).
        HELP! AGAIN!  This thing is driving me CRAZY, any help would
be GREATLY appreciated.  

thanks again!

Using RH 6.0 is a misguided proposition (and it always was, at least on
Alpha).  It has tons of bugs all over the place and they will be poping
out regularly if not here then there.  Some of them are fixed in updates
but fighting with these bugs is just not worth your time.  The current
6.2, which is avialable for quite a while, plus its security updates, is
in _much_ better shape overall and should be installed instead.

try to connect to the bnc port, I had a similar problem, with the
original kernel in the Red Hat 6.0 only the RJ port works...

1. Can you sandwich valid IP networks in between invalid IP networks?

Let me see if I can explain what I mean by sandwiching valid ip networks.
My networking/routing knowledge is abit rusty so if people find errors in
my logic, please point them out.

I've got a customer who has got 5 discontiunous Class C networks, i.e.
207.x.x.x, 204.x.x.x, 63.x.x.x ....  They have a two T1 lines coming to a
Cisco 2600 router via the serial connections of the router.  They burn a
whole Class C network for the ips of the ethernet ports of both the Cisco
2600 and the Cisco 7200 that it attaches to.  These two routers are
attached via a crossover cable.  All other Class C networks attached to
the Cisco 7200.  This setup basically burns the whole Class C, just to get
a connection from one router/network to the other valid networks attached
to the larger router.

So visually it looks like:
ISP=={2 T1lines}==>2600(207.x.x.1)<-{crossover}->(207.x.x.2)7200
and off the 7200, other Class C networks.

Keeping with this same configuration, is it possible to replace the ip
addressing scheme between the two routers with that of a private address
range?  Since private addresses are not allowed on the internet, would
that invalidate this configuration and cause routing problems?  If all local
routers know how to get to these 7200 attached Class C's via static
routes, is it possible to get away with a private network between the
Cisco routers, i.e 192.168.1.1, 192.168.1.2, netmask 255.255.255.252 ???

What I am seeking is a solution that will move that unused/burned Class C
network to a different port of the Cisco 7200, still utilize an IP
networking/addressing scheme between the two routers, to allow for the
near future addition of a Checkpoint Firewall box between the two routers,
instead of just a crossover cable.  This solution will all be NAT free.

Can this situation work, or will I need to use NAT on the Cisco 2600 to
disguise the 192 net and make sure that it is not seen from the world.

Any insights would be most appreciated.
TIA
