sendmsg: Operation not permitted on wireless router


Hi all!

I have got this network setup:

adsl modem (192.168.1.1)
|
wireless router (192.168.2.1) ----------- Win...s laptop (192.168.2.101 by DHCP)
|
Kubuntu 7.10 laptop (192.168.2.103 by DHCP)

Subnet mask is 255.255.255.0 for both adsl modem and linksys router.

The wireless connection works fine on my W.....s laptop.

On Linux, I use KNetworkManager to detect the router and get the ip from its DHCP server. However, I cannot access the Internet: when I issue
> ping 192.168.2.1
I get "sendmsg: operation not permitted".

This is the output of
>ifconfig eth1

eth1 Link encap:Ethernet HWaddr 00:1C:BF:02:FF:61
inet addr:192.168.2.103 Bcast:192.168.2.255 Mask:255.255.255.0
inet6 addr: fe80::21c:bfff:fe02:ff61/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1
RX packets:14 errors:13 dropped:31 overruns:0 frame:0
TX packets:3 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:53518 (52.2 KB) TX bytes:2544 (2.4 KB)
Interrupt:19 Base address:0xe000 Memory:dfcff000-dfcfffff

I have been trying to bypass KNetworkManager by playing with the command line. What I find strange is that I get DHCPACK from 192.168.2.1 by issuing "dhclient eth1", but then I cannot ping it.

Can anybody help me to sort out this?

Thanks

Joe

It could be any number of things. What is the vendor string and VendorID:ProductID as reported by 'lspci'?

Use 'lspci' to get the PCI Bus ID : Vendor String, then 'lspci -n' to get the PCI Bus ID and VendorID:ProductID

If firmware was not correctly loaded, you can get that error message. Not all wireless gizmos need to have firmware loaded by the driver though.

Hi pinniped. Thanks much for the assistance.
lspci gave me quite a bunch of stuff. Maybe what you want is the following:

Inter Corporation PRO/Wireless 3945ABG Network Connection.

after lspci -n I get:
0280: 8086:283e (rev 03)

This is definitely a problem with the machine rather than with the router. On the other machine (toshiba satellite) Linux seems to be working fine. So, the problem is definitely with the X61 Lenovo machine.

What do you think?

Joe
