Dear Members!
I have FreeBSD 7.1 with squid proxy running. PF is configured. Last few days i am facing some problems. Browsing is stuck time by time on clients machine. I tried to ping my local network from my FreeBSD server there i found the issue. here is the output of ping. [root@proxyServer ~]# ping 10.11.0.3 PING 10.11.0.3 (10.11.0.3): 56 data bytes ping: sendto: Operation not permitted ping: sendto: Operation not permitted ping: sendto: Operation not permitted 64 bytes from 10.11.0.3: icmp_seq=3 ttl=64 time=0.111 ms 64 bytes from 10.11.0.3: icmp_seq=4 ttl=64 time=0.147 ms 64 bytes from 10.11.0.3: icmp_seq=5 ttl=64 time=0.099 ms [root@proxyServer ~]# ping 10.11.0.5 PING 10.11.0.5 (10.11.0.5): 56 data bytes ping: sendto: Operation not permitted ping: sendto: Operation not permitted ping: sendto: Operation not permitted 64 bytes from 10.11.0.5: icmp_seq=3 ttl=64 time=0.111 ms 64 bytes from 10.11.0.5: icmp_seq=4 ttl=64 time=0.147 ms 64 bytes from 10.11.0.5: icmp_seq=5 ttl=64 time=0.099 ms On DNS queury [root@proxyServer~]# nslookup www.yahoo.com ;; connection timed out; no servers could be reached [root@proxyServer~]# nslookup www.yahoo.com Server: 10.11.0.9 Address: 10.11.0.9#53 Non-authoritative answer: www.yahoo.com canonical name = www.wa1.b.yahoo.com. www.wa1.b.yahoo.com canonical name = www-real.wa1.b.yahoo.com. Name: www-real.wa1.b.yahoo.com Address: 87.248.113.14 As you can see some time its getting response and some times not. If I stop (PF) then its working fine. Is there any traffic load issue or PF issue? or any kernel tunning required for heavy traffic. Please help Regards, Umar |
