very slooooooooow prompt via Telnet

[Didier Morandi_2]

I have a PC with address 192.168.0.1/255.255.255.0 and an Alpha with address 192.168.0.2/255.255.255.0 on a DSL modem/router.

I have TCP/IP 5.3-10 on the Alpha and XP-SP2 on the PC.

When I Telnet from the PC to the Alpha (with KEA-VT that I use for that purpose since ages, but without a router) I experiment a 30 seconds delay before I get my USERNAME prompt. After that, all is fine.

Why?

Thanks,

D.

(for a come back, that is a come back. Good questions... :-)

My satellite is now up and running. I configured TCP/IP on DTL02, then TELNETed to DTL01 and I get my prompt at once...

Didier,

It looks like you need to get a timeout, and then a second chance that succeeds.

Are you connecting by name or by IP address?

If by name, you should look into DNS first.

Without further info, my guess is that you have 2 DNS servers, the first of which can not find the address, and after timeout the second can.

hth.

Didier,
what do you mean "I configurated TCP/IP" ?

How about

ALPHA$ ucx set host pc/address=192.168.0.1

and try the telnet from PC again. Because the ALPHA now knows a name for your client at 192.168.0.1, it does not need to do DNS lookup.

And the DNS lookup anyway fails so that is the reason for timeout.

telnet to SL01 - from PC or from DSL02?

re: Jan
By IP address

re: Antonio
I set up TCP/IP on the Alpha to be able to receive incoming Telnet connections

re: Veli
BINGO: that was it. Have one for me :-)

re: Willem
from the PC. From the other Alpha it was ok.

Thanks for all.
You are wonderful.

ps: who is that Veli guy I never heard about??? :-)

you can disable the lookup of the IP address of incoming connections by
TCPIP SET SERVICE TELNET/LOG_OPT=NOADDR
TCPIP DISABLE SERVICE TELNET
TCPIP ENABLE SERVICE TELNET
Note this will disconnect all telnet sessions.
