Hi,

Can anyone suggest possible solutions to a problem that I am having with
a newly-inherited Sparc 20?  Both FTP and Netscape report 'TCP/network
unreachable", even when logged on as root.  I can telnet and ping out
from the same shell used to open Netscape, run an x-term from a pc to
the solaris machine and ftp into it.  The Sparc is running SunOs 5.7 and
(I think) Solaris 2.4.

Thanks in advance,

Bill

Are you behind a firewall?  If you can ping and telnet, you should be
able to ftp and http, unless someone is filtering based on ports.  If
you think you have a route problem, include more route info.

You may have an invalid proxy configuration. Check in

Thank you for the suggestions posted, especially to Adam who emailed to
suggest defining a default router - problem solved!

1. Newbie TCP/IP Ethernet problems (??)

Hey all....

I just finished installing Slackware Linux 2.0.27 on a P75 pci
motherboard.  I am using a 3COM 3c503 PCI 10MBps NIC.

When I try to access the http server, FTP or Telnet across the LAN,
there is an unreasonably long delay before I get a response.  In
Telnet, once I finally get the login prompt, everything is fast and
responsive as it should be.  It takes over a minute before I get a
login prompt, but once I've logged in, it's all normal, 'ls' prints
out the directory contents at breakneck speeds, and everything else is
fine.

I've set up eudora to log into sendmail to check mail, which works
fine, no delays like with FTP, Telnet, or HTTP.  I suspect inetd, but
in the http.conf, the server is configured as "standalone", so I'm not
sure that inetd has anything to do with http's slow response.

Is there some setting that I overlooked that defaults to some sort of
delay?  

The only clue to a possible problem is a  message during boot that
says something to the effect of  " (Jumper card to enable sharing)"
near the network card's initialization.  If this is the problem, what
do I change on a NIC that has no jumpers??

Any help is appreciated.  Please email the address below, I've altered
the information in my headers to prevent the spammers from trolling
for my address.
