Fw: [Dx4win] Telnet via Cable Modem Timeout

[Dan Szymanski]

Maybe I am out of line here or something.

However, has anyone who is experiencing dropped sessions ever talk with the
SYSOP of the node they telnet into regarding this issue?  I have yet to see
any reference of any correspondence with the Clusters SYSOP to date.
Sometimes the Cluster SYSOP have a better means to give a reason for the
dropped session. I believe all telnet sessions are logged at the Cluster.  I
am not trying to disprove some of the thoughts being talked about.  I am of
the opinion that many nodes we telnet into depend on a cable modem for
broadband connection as well. However while I am at work, I normally connect
to K4JA via a telnet session.  No,  I am not using a cable modem but do have
a real fiber based DS-1 line with router and all the IT supporting hardware
one would expect a business and its IT department to have. OK, I admit to
the fact somewhere in the path QWEST is involved with the DS-1. But I will
leave that part out of the equation for now.

While I don't really need to or use DX4WIN at work, I do use WINPACK 6.80 as
my telnet terminal. I admit to having dropped sessions experienced as well.
I don't have time to look at this while at work, I just know it does happen
to me.  I also know at times my connection to the Cluster host even gets
refused for short periods of time.  I can't believe I have bad hardware in
ever instance, maybe outdated firmware.

I have talked with the SYSOP for K4JA.  A little insight.  I found out there
is a AR Cluster SUPER SYSOP who single handed manages just under two dozen
AR Cluster nodes across the country.  Boy talk about network management at
its finest. Surprise, I have discovered via multiple emails exchanged even
cluster nodes running software such as AR Cluster are not totally bullet
proof.  Even with some of the more recent software updates made to it.
Those that are running the CLX package (that would be Linux based) also have
there weakness. So I guess we can take MicroSlush out of the picture for now
at least.

So maybe we need to get some input from those who know, run and manage the
clusters for us.  I don't see why we need to beat ourselves up all the time.
Oh, I do see some relative merit of advantage for a CISCO based router @ ~
$1,500.00 or so verses say a Netopia R7100 router or LinkSys gateway router
posted on eBay for ~ $ 70.00. I don't care what version of firmware you have
installed.

In my own world, I have visions of running a AR Cluster node offering
telnet, replacing the DOS based version currently on line at home.  Some of
the networking pieces are starting to fall into place for me.  Thanks in
advance.
