[Serusers] Ser-0.9.0 / PA Module / xten eyeBeam - sr-users

18 Mar 2005

Hey all,

	Trying to get the PA module working but I'm having some problems. From 
the logs on the server:

...
  Mar 18 14:45:08 ser1 ser[30085]: parse_hfs(): Error
while parsing headers
 Mar 18 14:45:08 ser1 ser[30085]: handle_subscription(): Error while parsing message
header
 Mar 18 14:45:08 ser1 ser[30085]: handle_subscription about to send_reply and return -2

	And the packets to and from SER look like this from eyeBeam's log. 
ngrep confirms the messages are the correct.

	Looking through the code from subscribe.c we're looking for From:, 
Event:, Expires: & Accept: all of which are present in the SUBSCRIBE 
request.

...
  if ( (parse_headers(_m, HDR_FROM | HDR_EVENT |
HDR_EXPIRES | HDR_ACCEPT, 0)
                                 == -1) ||

                 LOG(L_ERR, "parse_hfs(): Error while parsing headers\n");
                 return -1;
         } 

	Anyone see this before and have a fix or work around?
