Could it possibly be for communication with a DNS server ? Have you tried sniffing UDP packets sent to/from this port? -ascs -----Original Message----- From: Richard de Vries [mailto:richard_devries@xxxxxxxxx] Sent: Wednesday, July 05, 2006 7:07 PM To: users@xxxxxxxxxxxxxxxx Subject: [users@httpd] Apache listening for UDP requests? While debugging an issue on one of my apache webservers with lsof, I noticed the following: httpd 16679 http 23u IPv4 0x30008c5fa88 0t0 UDP *:41034 (Idle) httpd 16679 http 27u IPv4 0x30008bf4d20 0t0 UDP *:* (Unbound) httpd 16679 http 28u IPv4 0x30009526088 0t0 UDP *:* (Unbound) httpd 16679 http 29u IPv4 0x300084f32e8 0t0 UDP *:* (Unbound) httpd 16679 http 30u IPv4 0x30009590e68 0t0 UDP *:* (Unbound) httpd 16679 http 31u IPv4 0x300094087f0 0t0 UDP *:* (Unbound) httpd 16679 http 32u IPv4 0x30008edf0d0 0t0 UDP *:* (Unbound) What does this mean? Is Apache listening for UDP requests? If so, why?
