Hi, I checked this issue again and again. I found that if I start delegated with RESOLV=file,dns or whatever (even if it's the same as the default value RESOLV=cache,file,dns,sys), these 2 UPD ports will not appear in netstat -apn in my linux box. Is this a bug?

Hi, I am running a current version of delegate in a linux box as a FTP proxy, I found that delegated listening on the tcp 21 port, but also running on 2 UDP ports something like this(netstat -apn) tcp 0 0 0.0.0.0:21 0.0.0.0:* udp 0 0 0.0.0.0:1054 0.0.0.0:* udp 0 0 0.0.0.0:1055 0.0.0.0:* so, what do these 2 udp ports for? I tried tcpdump to check the traffic on these ports, but find nothing. I know that squid also running on one udp port for DNS stuff, is it something similar in delegate case? thanks a lot for any info. Jeff
