Samba - smbd: Unable to open printcap file /etc/printcap for read!
To stop samba from filling the log with entries like those:
Apr 22 13:34:30 unnamedsrv smbd[868]: [2008/04/22 13:34:30, 0] printing/pcap.c:pcap_cache_reload(159)
Apr 22 13:34:30 unnamedsrv smbd[868]: Unable to open printcap file /etc/printcap for read!
add following lines to your samba configuration file “/etc/samba/smb.conf”:
load printers = no
printcap name = /dev/null
You don’t have to restart your samba server, it re-reads the configuration by itself.
