RH 9.0 - keyboard slowdown - possible network problem??

[drwoo123]

I just installed RH 9 and am pretty much a newbie at this whole thing.

I noticed something weird happening. When I am typing at a command line from my windows machine, I noticed that there is a delay from when I type to when it gets shown on the screen. This usually only happens when I am typing fairly fast, lets say 30WMP. But it gets quite annoying waiting for a word to show up, and then typing backspace, and waiting to see if backspaced the correct number of times.

I think it may be a network issue because well I havent changed anything on the machine other than during the installation it asked for incoming services and I check off ssh and ftp.

Another simple test that I ran is this. I tried loading emacs and a C program I wrote that was about 400 lines.

On my windows machine using SSH it took 46 seconds for it to fully render the window.

From a friend's RH 9 machine in a different town over cable modem it took 19 seconds.

When I sit down locally at the console, neither the typing problem appears, and emacs loads in about 2 seconds.

Finally since I am running an X-Server (Xwin32) on my windows machine, I noticed that not much data is actually being sent to the windows machine, IE it sends a bit, stops, sends a bit more, stops. (using taskmanager in winxp).

I am connected to the machine through a 100MB switch, so that isn't the issue.

Here is the setup

AMD Athlon 800
512 RAM
40GB HD

I am the only person connected, and like I said I just installed it yesterday, with the default of everything installed. I did actually use redhat-config-network to input my hostname (where does this get stored btw??).

Other than that no changes. Is there anywhere I should be looking to begin trying to trace the problem.

I am assuming that you mean that your ssh'ing into a seperate RH box from your windows box on the same lan.

Maybe it's packet loss. A bad connection in the wire itself or maybe a bad port in the hub. Try switching new cables to it and try a different port on your hub or switch. Make sure that the contacts are clean etc etc.

Also try pinging from your windows box to your linux box and vesa versa. Also try the -f switch to flood your network by pinging as fast as you can from the linux box.

More of an update. Problem turns out to be hardware related. When I plug my laptop into the same hub that has my linux box and ssh / use emacs etc. it is blazlingly fast. Same thing only I unplug the laptop from there and use the wireless connection in my house, the setup is roughly 20 times slower (I know wireless is 11MB but still shouldn't be that kind of difference). I have a kingston hub - weird thing that happens is the following, the link light that is connecting that hub to my router blinks on and off every time there is a delay in my typing.

Meaning the following occurs.

1. Using a wireless setup - i ssh into linux machine - and then start typing while watching the uplink light on the hub (connected to a wireless router).

2. As uplink light vanishes for 1 second, which coincides with the delay in my typing.


I switched routers to make sure it wasn't my router that was bad, and the problem remains.

So I have the following hardware.

1. Kingston 8 port hub.
2. Netgear MR814 Wireless Router
3. Netgear RT314 Wired Router (my older one).

Currently the setup is Internet Connection -> MR814 -> Kingston Hub -> Linux Box.

I tried Internet Connection -> RT314 -> Kingston Hub -> Linux Box and same problem so I know its not the router.

Now I am goign to try Internet Connection -> MR814 -> RT314 -> Linux Box and see what happens.


My question is really, should the cables (all straight through and CAT 5) be connected to any particular ports on the routers. I know for the Kingston it has to be plugged into the uplink port (port 8) and then I set the switch in the front to straight through (maybe I should set it to crossover - i tried and both seem to work just fine -- ??).
