           Summary: print to file: left over UDP-port remains open
           Product: kdeprint
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kde-print-devel kde org
        ReportedBy: franke.daniel gmail com


Version:            (using KDE KDE 3.5.0)
Installed from:    Compiled From Sources
Compiler:          gcc-3.3.6 
OS:                Linux

I'm running KDE-3.5 and cups-1.1.23. Whenever any KDE application prints to file (PDF), an open UDP port is left over.

How to reproduce:
 * make sure that there is no open port for konqueror: `lsof -i | grep konqueror`
 * print this bug report to file (PDF)
 * check again the list of open ports: `lsof -i | grep konqueror`

COMMAND     PID   USER   FD   TYPE  DEVICE SIZE NODE NAME
konqueror  9207 daniel   14u  IPv4 4469467       UDP *:52746


These UDP ports may be accessed from any host:
remotehost $> nmap -sU <myhost> -p 52746

Starting nmap V. 2.53 by fyodor insecure org (www.insecure.org/nmap/ )
Interesting ports on <myhost> (<myip>):
Port       State       Service
52746/udp  open        unknown

The port is closed if and only if the printing application is closed.

I reported this issue to the kdeprint maintainer Christian Tibirna about three months ago, he acknowledged to submit this report.
