bad networking problem
Anne Wainwright
There is always a hassle to contend with when setting up my paradox
automated student used book purchase system each year (this network put
up yearly at this time for a Feb and Mar run). It involves bringing in
windows computers (we run linux for everything else now) and setting up
the network and getting it all running. This year we had a really
frustrating time, and I hope you won't mind if I share the problem and
solution with you.
Following a 31st Jan 2003 post from Liz on configuration issues we have
been glued to the letter of the law ever since. At first we did think
this was a configuration issue and spent a lot of unnecessary time
chasing this line, particularly of course the path to the .net file,
local share, etc.
The problems were twofold
1. the operation of the main .fsl was very slow, you could almost see the
form think
2. we could only run the server and one client m/c or lockups occured
and then we found pdoxusrs files in \\servername\C\Pdoxdata\myapp\Private
whereas they are set to reside two steps back from that in the PdoxData
directory.
In the end we had to conclude the issue did not resolve around settings
in idapi or indeed any software issues. I note that all machines run
their own version of pdox9 with the same bde config file copied to all
clients. A model pdox setup that I felt in the end was not at fault.
I work from home & ssh to the office, use a GUI client to access our main
postgresql database across the net, or ftp files to and fro. And here a
few weeks back was an issue. All of a sudden we could not ftp, all other
connections yes, ftp no. No amount of investigation would solve this but
I had become suspicious of the router as the ftp setting on the NAT page
had evaporated and subsequently reinstatement did not give ftp access.
This in fact was the key to the whole issue. When we decided to swap out
the router with a replacement we were back to normal. Full speed, all
clients connecting and running fine.
So I wouldn't pretend to know the inner workings of pdoxusrs.net and .lck
files, but obviously a poor LAN connection can have a serious affect on
client-server operation. A salutory lesson in keeping the hardware up to
scratch.
hope that all of you regulars are keeping well.
Just for the record, this is a dlink router. I am looking for a
replacement with the admin page accessible via a text-only browser like
w3m since this is what I have on the server box. A long shot, but any
suggestion welcome.
best regards

Let me know if you find one! (My preferred browser is Lynx.) However,
I suspect that only high-end Cisco routers and similar will do what you
want.
