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) || (_m->from==0)||(_m->event==0)||(_m->expires==0) || (_m->accept==0) ) { paerrno = PA_PARSE_ERR; LOG(L_ERR, "parse_hfs(): Error while parsing headers\n"); return -1; }

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