Dear LPRng-Developers,
 
we’re using LPRng for years now and it works quite fine, but currently we are struggling with a IPv6 POC of LPRng. We tried to enable IPv6 capability. Each time we start the daemon it throws the error:
Fatal error - Cannot bind to lpd port '515'

OS: SLES11 SP2 (Linux Kernel 3.0.31-0.9-default)
LPRng version: 3.8.35

Starting the daemon without IPv6 works fine. But after activation of ipv6 option in lpd.conf the error appears.

We checked whether there is another LPD running (lpd, cups) and nothing appears. In addition the port 515 is not used by any application.

# netstat -antup | grep -i 515
#
# ps -eaf | grep -iE 'lpd|cups'
#
# lsof -i TCP:515
#

no findings.

I'm quite stuck and I have no idea what to check further. Is it possible to request help from your side?
 
Thanks in advance.

Gruß / kind regards
