• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Nir Dremer 2005-09-15 00:51:49 UTC]

Using sys-apps/baselayout-1.12.0_pre8-r2 and initlizing net.ethX i see the
following errors:

grep: /proc/net/wireless: No such file or directory
grep: /proc/net/wireless: No such file or directory

This machine has no wireless configured in the kernel not configured either in
conf.d/net.

Other machine which has wireless enabled does not have this error.

Reproducible: Always
Steps to Reproduce:

1. remove wireless support from kernel.
2. recompile and reboot.
3. /etc/init.d/net.eth0 restart

bad uber, always use 'grep -s' when reading /proc files ;)

I'm not seeing this on my server which does not have wireless.
Do you know where is error is? files, line numbers?

If not, could you set RC_VERBOSE="yes" in /etc/conf.d/rc and post the full
output of net.eth0 starting including the errors.

Thanks.

Created attachment 68564 [details, diff]
test for /proc/net/wireless

OK, I think I have it fixed. The issue looks like wireless-tools and/or
wpa_supplicant was installed and the kernel did not have wireless.

Please test this patch which should fix it.

[Comment 4 Nir Dremer 2005-09-16 03:22:56 UTC]

Patch solves the problem.


Roy: Impressive work finding the combination that causes the problem quickly..


Thanks!

[Comment 5 Roy Marples (RETIRED) 2005-09-16 04:27:01 UTC]

Thanks :)

Will be in baselayout-1.12.0_pre9

[Comment 6 Roy Marples (RETIRED) 2005-10-11 08:21:15 UTC]

Fixed in pre9
