ifconfig : socket: operation not supported

[Rainer von Bongartz]

After a server crash (due to power failure)
the lan cards cannot be initialized.
lanscan sees the lan cards but ifconfig gives the error

ifconfig: socket: operation not supported

This is for all network cards.


Any ideas ??

HI !

From ifconfig man page : "Messages indicate if the specified interface does not exist, the requested address is unknown, or the user is not privileged and tried to alter an interface's configuration."

In your case, it seems that the 3rd is the more likely to match the problem. If your system crashes, it may have leave files (sockets ?) that you don't have right on.

Maybe you could get $? after ifconfig completion.

Hi Rainer,

what is the exact ifconfig command that you launched?

Best regards,
Fabio

Fabio:

even the sinple form

ifconfig lan0
or
ifconfig lan1

produces

ifconfig : socket: operation not supported

What is the output from lanscan ?

lanscan looks pretty good, displaying

landiag also shows no problems

# ioscan -fnC lan
Says.. Does it shows the Claimed status.. proper driver loaded .. H/w State .. ??

lanscan -fnC lan:

Hardware is claimed, State is up driver is correct and devices files (/dev/ether* , /dev/lan*) exist

Hi,
See if this works

# ifconfig lan0 plumb
# ifconfig lan0

Regards,

[Rainer von Bongartz]

Got it:

ifconfig : socket: operation not supported
is an alias for
/tmp file system full !!!!!!!!!!!!!!!!!

Due to the crash a dump file was writte to /tmp which filled the files system 100 %.

Obviously ifconfig need some disk space in /tmp to work.

After removing the crash dump and so freeing space in /tmp ifconfig worked

It's maybe time to create /var/adm/crash :)

Agreed.....

I'm having a very similar issue, but disk space is fine. I've done a clean install of 11i on 2 A500's, but the system never lights up the port (I can see this via the network switch console). PLEASE HELP!

Also, sam tells me:
There are currently no network interface cards installed on this system.
