Network Problems

Post by Nathan Stratt » Thu, 18 Aug 1994 06:03:19

        Hi, I am having problems with my network and wanted to know
what I should do. I am running Linux 1.0.8 on a 486 DX2 66 with a NE-2000
network card. My network address is, I can telnet to that
address and log back in but I can not telnet out. When I ping the box
from a PC I get no responce. Hos can I check to see what is wrong? I have
installed the software and that did not help.
        If you can help please post, because Netcoms's mail is not
working and I will not get if for many days.

1. Network problems with 3c595 on 100T network (detailed)

        I have a networking problem which I have not managed to solve after
reading the relevant HOTWO files. Any help will be appreciated.

  Intel Pentium Pro with 3Com 595 100Tx card connected to 100T network.

  The machine has WIN/NT installed and manages to access the network.

  - I have installed Slackware 3.1 (from InfoMagic CDROM)
  - run "netconfig" with appropriate parameters (double checked)


  - Kernel recognizes right device
  - No error messages at boot time

  - ifconfig shows the device setup, but shows 0 on all TX and RX counts,
    including errors counts.
  - same for /proc/net/dev

  - routing table seems ok (as far as I understand these things)

Yet, I can't run a single network application.

ping to my gateway just hang. When I press ^c, it reports "NN packets sent, 100% packet loss".

I tried to ping the machine from another machine, and again no

The interesting thing is that "ifconfig" keeps insisting that nothing was sent
 nor transmitted.

The only thing that I can think of is that the device parameters are not set
right. In particular "ifconfig" reports:

eth0  Link encap: 10MBps Ethernet ...

when the net should 100MBps.

Can this be the problem? If so, how do I set the right mode for the device?
