I have a few rack mount hubs that I no longer need.  These are 10BT  and
range from 12 to 24 ports.  SMC, HP and SynOptics.

They are free.  Email me if you are interested.

Hey,

I've got an odd problem that comes up with one url, www.taigtools.com .
When I point programs like elinks, wget, mozilla, or konqueror at
taigtools.com on my debian laptop, debian desktop, or the remote debian
server I'm ssh'ed into, they timeout.  On my zaurus pda, my wife's
apple, or a second redhat server I'm ssh'ed into, no problem.

What could the problem be?  It took me a while to pin this much down.

The debian server is a recent debian server at vpslink.com, running
Linux version 2.6.8-022stab078.14-enterprise (root [ at ] kern268 [ dot ] build [ dot ] sw [ dot ] ru)
(gcc version 3.3.3 20040412 (Red Hat Linux 3.3.3-7)) #1 SMP Wed Jul 19
16:24:18 MSD 2006 and seems to be a fresh sarge install.

The debian desktop is running
Linux version 2.6.17 (root@Knoppix) (gcc version 4.0.4 20060507
(prerelease) (Debian 4.0.3-3)) #4 SMP PREEMPT Wed May 10 13:53:45 CEST
2006 and is an unstable install off a recent knoppix disk.

The redhat server is
Linux version 2.4.29-grsec (root [ at ] chrome [ dot ] nocdirect [ dot ] com) (gcc version 2.96
20000731 (Red Hat Linux 7.3 2.96-113)) #1 SMP Fri Feb 4 15:36:57 CST
2005

And the zaurus is running 2.6.15 .

Is it some debian anti-machinetool thing?

Regards,
-Sebastien Bailard

Sebastien, this could be a problem with explicit congestion
notifications (ECN).  You can disable it like so...

echo 0 > /proc/sys/net/ipv4/tcp_ecn

(as root)

The fault is at the web server or its router, not your kernel.  The
older kernels had ECN disabled (or maybe not implemented).

I'm looking to get rid of my back issues of Linux Journal.  I think I've
got every issue going back to 1998 or so.

If you're interested, they're yours.   First person to get back to me
before next Thursday ( my paper recycling day ) gets them.

Alternatively, if anyone knows of someone or some group that would want
them -- the Ottawa Public Library doesn't, but perhaps some school or
computer training centre might -- please let me know.    I'd really
prefer that they go somewhere useful, rather than the recycle bin.

Cheers,
Dave

If that fixes it then a more permanent solution is to stick

net/ipv4/tcp_ecn=0

into /etc/sysctl.conf
