Re: [irda-users] Re: IrLAN not working

[Kees S. <kee...@ho...>]

Hi Zdeněk

I had the same problem, but after some experiments, i found out that the
hotplug system was giving me troubles.
When you do modprobe irlan, the hotplug system tries to configure it, and
since this is not setup right, the configuration never ends. When you then
do ifconfig, it hangs, since hotplug is already doing that.
I had to modify the net.agent file, in order to stop hotplug from
configuring. After that I was able to do ifconfig irlan0 192.168.2.2 netmask
xxxx broadcast xxx and irlan works fine.
I am using redhat 8.0 with kernel 2.4.18, but hotplug is probably installed
on many other systems as well.

Hope that this helps you,

Cheers,
Kees.
