Re: segfault error
Hi, FYI, I just had the same issue and went into the code that leads to this. The issue is that with *salted* passwords, FreeeRADIUS sometimes decides to base64-decode *twice*. The first round does the right thing; the second one *may* produce garbage (attempting to decode an already-decoded string). It only does so if the decoded value from first round looks like it could be a base64-encoded string (e.g. contains an = sign very early) AND if your salts are long enough to trick FreeRADIUS into thinking that there's something to decode still. Hoping to get this fixed for 2.2.1. Stefan On 02.05.2013 19:33, Chris Taylor wrote: I forgot to include my OS and kernel type.

on-radius01 kernel: radiusd[10038]: segfault at 73d87000 rip
003c6c07b5bb rsp 73d83c08 error 4
Check that you're really running v2.2.0. Sometimes scripts point to old
installations.
I turned on core dumps to see if I could get any more details out of it, but
I could not make it crash after that.
Did you follow the instructions in doc/bugs? That says how to find the bug.
Any ideas as to what this could be I can post my -X output but all it says at
the bottom when it stops working is segfault.
doc/bugs has detailed instructions for just such an occasion.
Alan DeKok.

Re: segfault error
Hi, I did some more debugging and I always seem to get a segfault at the same place. Is there something I should be looking at on the LDAP backend? i'd like to knwo what you are doing, how you have this configured.and why your server thinks '45270' or 'bradly' or SSHA encrypted, its likely you're forcing somthing to occur which is truly stuffing the SHA libraries when they try to evaluate the not SSHA1 hash as per the docs, radiusd -X output alan - List info/subscribe/unsubscribe?
