Suddenly Lost Network

Suddenly Lost Network

Post by Douglas J. Olivie » Sun, 15 Feb 1998 04:00:00



I have had 2 boxes linked with nics for 6 mo. and all of a sudden I've
lost the network, cant ping or anything reloaded Linux on both and
cannot find errors.
Here my setup:

bigkahuna
inet1
/sbin/modprobe ne io=0x0340 irq=5
IPADDR="24.128.82.xx   # REPLACE with YOUR IP address!
NETMASK="255.255.255.0" # REPLACE with YOUR netmask!
NETWORK="24.128.82.0"   # REPLACE with YOUR network address!
BROADCAST="24.128.82.255"       # REPLACE with YOUR broadcast address,
if you
                        # have one. If not, leave blank and edit below.
GATEWAY="24.128.82.1"   # REPLACE with YOUR gateway address!
/sbin/ifconfig eth0 ${IPADDR} broadcast ${BROADCAST} netmask ${NETMASK}
/sbin/ifconfig eth1 192.168.1.1 broadcast 192.168.1.255 netmask

sbin/route add -net ${NETWORK} netmask ${NETMASK} eth0
/sbin/route add -net 192.168.1.0 netmask 255.255.255.0 eth1
if [ ! "$GATEWAY" = "" ]; then
 /sbin/route add default gw ${GATEWAY} netmask 0.0.0.0 metric 1

/sbin/ifconfig eth0 ${IPADDR} broadcast ${BROADCAST} netmask ${NETMASK}

lo
default         bigkahuna.kahun 0.0.0.0         UG    1      0        0
eth0

As far as I can see all these are correct the eth0 on bigkahuna goes
outbound to the internet but I cant get the two boxes to even ping each
other.
I have replaced the nics on each end and the cable, with no luck , the
kernel shows the nics are active.
However I only see the yellow light on the nics no actvity indicated.

I have had the same problem with cheap NE2000 clone NIC!
This appeared after 1,5 day.

 
 
 

1. Networking Suddenly Lost in Redhat

Hi!

Until last week, my 755CD / Redhat 4.2 ran splendidly on PPP, TR,
and Ethernet.

Now, I cannot communicate at all. When I do a "netstat -rn", I receive
the headings, but no info, not even loopback.   Attempts to install or
change PCMCIA cards do not work.

I can, however, "dial" out with a modem, but there is of course no com-
munication afterwards.

I don't believe I changed any files or services recently - could anyone
suggest possible causes/corrections?

Thanks!   Hy
