Hi,
I got a segmentation fault when i tried to run freeradius (Versions
1.0.4, 1.0.5, 1.1.0 and 1.1.1) on Debian (Sarge) or Suse (10.0) with
options enabled in the attached config-file.
Meanwhile I found out that the segmentation fault happened because of
the following setting:
> bind_address = 0.0.0.0
No I replaced it with the default value
> bind_address = *
and everything is fine :)
Thanks for reading,
best regards,
Rainer
