Hello.

I am working with FreeBSD 2.1.6. After installing, I am having  some
networking problems. I try to ping a host on my network, and I am
getting an error message - "no route to host".

Is this a symptom of a mis-configured network card? I have a 3Com
3C90X. In the Userconfig utility, I saw no mention of this card - only
the 3C50X. Are these cards alike enough to operate with the same
driver?

Is there any way of starting up the Userconfig utility than entering
-c at the boot prompt?

Thanks

What do "dmesg" and "netstat -rn" say ?

Thanks for your help. After a bit of fiddling, I found that manually
entering 'ifconfig vx0 {my IP address} got the thing working.

Now - how to make this happen automatically at boot?

Have a look in /etc/sysconfig.  Something like

network_interfaces="lo0 vx0"
...
ifconfig_vx0="inet {my IP address}"

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

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

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

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

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

Symptoms:

  - 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
communications.  

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?

Thanks,

-Nir
