I started the download of Solaris 10 (11/06) CD images whose size is
about 2400MB from sun.com this morning. And I found the transfer rate
became 0byte/s about 10 p.m. JST. Mrtg graph shows that the
input/output of tlp[01] keep around 30kB/sec (including ssh session).

Now, the network of RaQ2 is almost down. And here are some commands
outputs.

I was running "tcpdump -n -i tlp0", "tcpdump -n -i tlp1" and "vmstat
-i -w 5" while downloading. The maximum rate of "soft net" was 29.

## Oops, why don't I use script to log all outputs...

And, tcpdump shows only SNMP, NTP, and SMB now. Dmesg and
/var/log/messages have no useful contents.

I suspected the local proxy (squid) performance or restriction, but no
doubt, because another Solaris download from FreeBSD/pc98 box on the
same segment with the proxy was fast enough and finished successfuly
in about an hour. This shows that ISP does not restrict the band width
nor max traffic.

Thanks.
