Your message have bugged me for a while, but now I found the reason for the long ping time to localhost.
I had both iplogger and ippl running. Removing iplogger I got: $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0.5 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=255 time=0.3 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=255 time=0.3 ms 64 bytes from 127.0.0.1: icmp_seq=3 ttl=255 time=0.3 ms 64 bytes from 127.0.0.1: icmp_seq=4 ttl=255 time=0.3 ms --- localhost ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 0.3/0.3/0.5 ms You have mail in /var/spool/mail/karl And stopping ippl I got: $ ping localhost PING localhost (127.0.0.1): 56 data bytes 64 bytes from 127.0.0.1: icmp_seq=0 ttl=255 time=0.1 ms 64 bytes from 127.0.0.1: icmp_seq=1 ttl=255 time=0.0 ms 64 bytes from 127.0.0.1: icmp_seq=2 ttl=255 time=0.0 ms 64 bytes from 127.0.0.1: icmp_seq=3 ttl=255 time=0.0 ms Regards, /Karl ----------------------------------------------------------------------- Karl Hammar Asp� Data [EMAIL PROTECTED] Lilla Asp� 2340 +46 173 140 57 Networks S-742 94 �sthammar +46 10 270 26 67 Computers Sweden Consulting ----------------------------------------------------------------------- From: xsdg <[EMAIL PROTECTED]> Subject: Re: multiple loopback devices?
