[hylafax-users] hfaxd & faxstat losing connection

[Thomas ADOLPH <thomas.adolph@xxxxxxxxx>]

Hi all,

I'm using Hylafax on a Debian (Sarge package, v4.2.1-5sarge3) and I'm having
some problems i don't seem to be able to resolve.

I got hfaxd running and listening on port 4559. when I first run faxstat
everything goes nice and smooth and it answers correctly. But if I re-run
another (or 10 others), I get the Q301 message, aka :

# faxstat
Service not available, remote server closed connection
No control connection for command

(hfaxd is still running)

I've enabled logging in hfaxd.conf and here's what i get for the first faxstat
connection :

Jul  5 10:24:52 localhost HylaFAX[22997]: servertracing = 0x1FF (line 54)

Jul  5 10:24:52 localhost HylaFAX[22997]: <--- 226 Transfer complete.


Everything seems fine, now the second faxstat connection :

Jul  5 10:24:53 localhost HylaFAX[23001]: servertracing = 0x1FF (line 54)
Jul  5 10:24:53 localhost HylaFAX[23001]: <--- 220 localhost.localdomain server
(HylaFAX (tm) Version 4.2.1) ready.
Jul  5 10:24:53 localhost HylaFAX[23001]: HylaFAX INET connection from
localhost.localdomain [127.0.0.1]
Jul  5 10:24:53 localhost HylaFAX[23001]: command: USER root
Jul  5 10:24:53 localhost HylaFAX[23001]: USER root
Jul  5 10:24:53 localhost HylaFAX[23001]: <--- 230 User root logged in.
Jul  5 10:24:53 localhost HylaFAX[23001]: FAX LOGIN FROM localhost.localdomain
[127.0.0.1], root
Jul  5 10:24:53 localhost HylaFAX[23001]: Lost connection to
localhost.localdomain [127.0.0.1]

Not so fine anymore. (It does the exact same thing when using telnet, however I
can issue numbers of other commands like HELP forever without losing connection,
it only happens after using the USER command)


I also straced the processes hoping to find something more useful, and here's
what I got for the working one (I'll only post the parts that are different)


28162 geteuid32()                       = 10
28162 fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
28162 read(3, 0x8092fe8, 8192)          = -1 EAGAIN (Resource temporarily
unavailable)
28162 fcntl64(3, F_SETFL, O_RDWR)       = 0
28162 write(3, "\1\0\0\0\1", 5)         = 5
28162 shutdown(3, 2 /* send and receive */) = 0
28162 close(3)                          = 0
(and continues after that)


And for the non-working one :

28177 geteuid32()                       = 10
28177 fcntl64(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0
28177 read(3, "", 8192)                 = 0
28177 fcntl64(3, F_SETFL, O_RDWR)       = 0
28177 write(3, "\1\0\0\0\1", 5)         = -1 EPIPE (Broken pipe)
28177 --- SIGPIPE (Broken pipe) @ 0 (0) ---


I also have the same hardware (computer and modem) running the same kernel and
hylafax version which is working correctly.

Any help would be appreciated.

Thanks
Thomas
