ping help

I'm at the end of my rope. I cannot swap pings between my slackware 10
box and my win98se box.


Here's ifconfig eth0:

Link encap:Ethernet HWaddr 00:50A:6E:A9:00
inet addr:10.1.1.1 Bcast:10.1.1.255 Mask:255.255.255.0
UP BROADCAST MULTICAST MTU:1500 Metric:1

<snip packet stats>

Interrupt:12 Base address:0x6000


Here's Run... winipcfg /all:

Ethernet Adapter Information
Adapter Address 00:50A:76:09:53
IP Adress 10.1.1.2
Subnet Mask 255.255.255.0



Both NICs are 3c905 and the vendor-supplied DOS diagnostics both ran
without a hitch AND swapped pings no problem. I'm thinking this is a
network configuration issue but I have exhausted the available
documentation and am still unable to ping. Thanks in advance to anyone
who can tell me what I'm doing wrong.

What are the gateways?

The gateways are irrelevant because these machines are both on the same
subnet. Please post the following:

* the output of the route command (route -n)
* Any ip filtering/forwarding stuff you have running (like the output of
iptables -L)
* the output of sysctl -a |grep -i net, and sysctl -a |grep -i icmp

can you ping 127.0.0.1?



How are you connecting the computers physically (be specific, what wires
are plugged into where)? Are you trying to use a peer-peer configuration
without a crossover cable?


Are you pinging a hostname or an IP address? If you are using name
resolution you will need to provide us with your /etc/resolv.conf file
contents and your /etc/hosts contents.


Post this and any other info you wish to volunteer and we should be able
to solve your problem.

Would be great you wouldn't, they contain often useful
information, helping us to understand the problem, even if they
don't tell you anything.

There's no need for a gateway if hosts are on the same subnet.

He should rule out cabling/etc first, is there a switch used or a
cross-over (bought/self-made?)? Is there a link at all shown by
the diagnostics LED on his NICs? Does (as root) 'mii-tool' output
anything? He should see something in the lines of:

eth0: negotiated 100baseTx-FD, link ok

Let's hear it for a stupid solution to an impossible problem:

Upon further inspection of the Slackware box, it seems the 3c905C's
RJ-45 socket has pulled off of the card only VERY slightly. Contact
between the socket pins and the printed circuit board can be described
as intermittent at best. This would explain the on-again-off-again
behavior that I've been experiencing with all manner of ethernet
connectivity.

Thanks to all contributers who took time out of their schedules to help
a guy with his linux box. This is the first and last time I trust a
used NIC implicitly.
