Keyboard input from Telnet sessions seems to be slow

[Roberto Gattinoni]

Hi all,
I've installed a new HP-UX 11.0 L2000 with 1Gbyte RAM on a LAN where there are a lot of PCs connecting to this machine via telnet. On the same LAN there is a D370 with HP-UX 10.20 to which users connected before the new machine was installed. It seems as if the keyboard input on the Telnet sessions on the new machine is "slower" than on the old one, although all batch processing is very fast (as I expected to be). The LAN card on the new machine is identified by lanadmin as HEWLETT PACKARD 10/100 TX HALF-DUPLEX.

Anyone can help?

Thanks a lot.

Hi,

Try to get your network card on 100MB full duplex !
Might help !

It may be that your NIC and the switch port have a mis-matched duplex setting. This often happens when using auto-negiotiation on 100Mb ethernet.

Verify your NIC's setting with:
lanadmin -x PPA#

Use "lanscan" to determine the PPA# for the NIC is question.

If the speed is not 100 Full duplex you can change it with:
lanadmin -X 100FD PPA#

That will also turn off auto-neg.

If you force the NIC into 100FD you need to force the switch into 100FD also.

I recommend to always force your servers and their switch ports to 100FD.

Hi Roberto,

Change the lan card setting as well as the switch port setting on which this system is connected to fixed, 100 MBPS, Full Duplex, Auto -neg off. Also check and install the 100BT patches for your lan card / system.

Hope this helps.
