Hi,
beginning two weeks ago I have a strange problem with my SLC 760 running pdaxrom 1.1.0beta1.
I have networks configured via WiFi, CF-netcard and bluetooth/cellphone. All of them worked perfectly, but starting two weeks ago in neither of them DNS is working. Maybe I changed something without taking notice.
As far as I see, all things like receiving IP-adress, writing /etc/resolv.conf and so on work fine. Networking works fine if I use the IP-adress but as I said not name resolution.
For your information I include some output from netstat etc after inserting the CF-Netcard:
#ifconfig

# cat /etc/resolv.conf
nameserver 192.168.0.1
Any idea what is going on there?

All the info you have posted would point to the nameserver (192.168.0.1) being the problem. Are you sure this is working? Have you tried a tcpdump to see where the packets are going?

Hi,
yes, I am sure it works. That's my home configuration with a fli4l-router (192.168.0.1), doing DNS, NAt etc.
The Desktop works fine just showing the same information for ifconfig.
When I use my cellphone and GPRS/bluetooth the correct DNS-Servers from the provider are in resolve.conf.
That is exactly the reason why I do not have any idea what is going on ...

OK - maybe the frame count (which I think is when things don't fit or collisions?) is an issue. Do you have a 2.6.14 kernel on 192.168.0.1? Try lowering the mtu if this is the case... (seems funny the DNS would be an issue, but)
Otherwise I'm out of ideas sorry.

I have same problem, with 1.1.0-beta2, but all connections with DHCP (GPRS, USB LAN and CF LAN) has a DNS error... but /etc/resolv.conf is OK! If I put a static IP and DNS this works

hmm... doesn't DHCP set up name servers also? If you are getting a valid IP address for a nameserver from the DHCP server, but there is no useful nameserver there, maybe this would override resolv.conf, and cause this problem? What is the nameserver setting on the DHCP server?
This seems like a general networking problem, rather than pdaXrom-specific, so if noone here can help you guys, I imagine there's heaps of value in other forums etc out there.

so a nslookup specifying the nameserver also errors?
nslookup <name> <nameserver>
