cable modem can't ping gate way

cable modem can't ping gate way

Post by KevinDTim » Tue, 07 Sep 1999 04:00:00



I know this looks like a previous post, but it is subtlely different.

gateway (24.7.97.1).  I am however able to ping another machine on the

switching the addresses of the machines (thinking that maybe my cable

but that doesn't seem to have any affect.

Here is my ifconfig output:

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Bcast:127.255.255.255  Mask:255.0.0.0
          UP BROADCAST LOOPBACK RUNNING  MTU:3584  Metric:1
          RX packets:88 errors:0 dropped:0 overruns:0
          TX packets:88 errors:0 dropped:0 overruns:0

eth0      Link encap:Ethernet  HWaddr 00:50:04:12:8E:6D
          inet addr:24.7.97.33  Bcast:24.255.255.255  Mask:255.0.0.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:37 errors:0 dropped:0 overruns:0
          TX packets:23 errors:0 dropped:0 overruns:0
          Interrupt:10 Base address:0xe880

Thanks in advance,

Kevin

p.s. remove the XYZ to email back, BTW I will read the posts here and
do not expect to get email.

First off check your routing table.  You should have your default route
(0.0.0.0) look something like the one below

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
24.2.97.0       0.0.0.0         255.255.255.0   U     0      0       26
eth0
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        4
eth1
192.168.2.0     192.168.1.2     255.255.255.0   UG    0      0        0
eth1
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        6 lo
0.0.0.0         24.2.97.1       0.0.0.0         UG    0      0      244
eth0

Note: the 192.168.1.0 and 192.168.2.0 are internal private networks and I
provide them just in case you also are routing internal traffic.

Once you have verified your routing table, reset your cable modem (there
should be a switch on the back which when pressed for 10+ seconds will
reset the modem completely)  This is primarily so that the modem will read
your MAC address and report it correctly (thus allowing the gateway to
properly route back TO you)

At this point you should be able to route through the specified gateway
and have it recognize you.

Andrew,

Well, its a little on the late side tonight (I'm dying to get to bed,
but I think you probably hit it on the head)  The routing is a good
guess, actually my route table looks almost exactly like this.

I will try it now (because I can't bear to wait)

Thanks much, I'll report back.

Well, I tried it and (by god) the little devil works like a charm!
Thanks from the bottom of my heart, I have been working on this since
6:00 pm (plus a little playing yesterday) and all of the hollering
could have been over hours ago!

Hallelujah!

I'm in the same boat. How do you look at the routing table.
