: This is most likely due to the fact that YOUR machine has no DNS
: records. When you try to FTP or telnet to a site, it attempts to resolve
: and reverse-resolve your address to confirm that your site is not bogus
: (or something). I have seen similar behaviour on LANs (that depend on
: DNS) when the nameserver is down. Start looking into the IP addresses
: and names that you are assigned when you dial in from OUTSIDE (the Internet
: side) with nslookup and see what you find.
When I had the same problem, it turned out that I had the value for the
$mtu variable set incorrectly. Check to see what the other end is using
and set it accordingly in your script (or manually, if you like).
Standard number to try are 296, 1500, and any multiple of 1024, up to 4096.
The command in the script should look like this:
get $mtu 1500
On UMC's SLIP server the value is 1500. But anyway, the symptoms I had
were *exactly* as you described until I resolved that problem.
Hope that helps!
