Recent problems with my cablemodem (using DHCP)

Recent problems with my cablemodem (using DHCP)

Post by Lorin Hochstei » Sun, 23 May 1999 04:00:00



Recently, I've been having problems connecting to the internet under
Linux. I connect using a cable modem, using DHCP to get an IP address.

I have a dual-boot Windows 95/Linux (Redhat 5.0) system, and my Windows
system has no problems connecting. However, recently the connection has
stopped working under Linux, and I don't have a clue why.

A netstat -rn gives me:

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt
Iface
24.200.88.0     0.0.0.0         255.255.255.0   U      1500 0          0
eth0
127.0.0.0       0.0.0.0         255.0.0.0       U      3584 0          0
lo
0.0.0.0         24.200.88.1     0.0.0.0         G      1500 0          0
eth0

However, I don't know enough to interpret this. Is this information
helpful? Also, doing an ifconfig tells me:

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:121 errors:0 dropped:0 overruns:0
          TX packets:121 errors:0 dropped:0 overruns:0

eth0      Link encap:Ethernet  HWaddr 00:10:5A:26:D7:EB
          inet addr:24.200.88.188  Bcast:255.255.255.255
Mask:255.255.255.0
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:977 errors:0 dropped:0 overruns:0
          TX packets:854 errors:0 dropped:0 overruns:0
          Interrupt:10 Base address:0xd000

Could anyone provide some advice?

I have the exact same problem.

When this happens and I do a netstat -r, I get the first 2 entries
quickly, but it hangs for a minute before listing the 3rd (default
gateway) entry.

I'm also looking for help on this problem.  If I find an anwser, I'll
tell you.

I should add that following boot, the networkings works perfectly, but
after an hour or so, I can't ping anymore.

1. RedHat 7.1 & DHCP using a cablemodem

Hi,

I've just installed RedHat 7.1  and tried getting DHCP working with my
Terayon cablemodem (ISP: NTL).

I recompiled the kernel (base 2.4.2-2) to enable the network interface card
(Intel EtherXpressPro 100) and this seems to have worked okay (link light is
on and ifconfig eth0, obviously minus IP address etc., displays no problem).

Have tried both pump and dhcpcd using the -h option but still doesn't work.

Anyone have any constructive ideas before I try a different distribution!

Cheers,
maddog
