    Hi,
    I have 2 pc link to each other. My client pc is using windows and the Server is RedHat Linux 6.0. I am facing a problem now, when I telnet into my server, it takes me about 90 seconds just to get the login prompt. Do anyone knows how to make it faster?
    Thanks.

    What kind of link are you using? Are you using a null modem cable or is it a proper network connection?

    Assuming you haven't accidently set a delay option, check the network latency by typing:
    $ ping <IP of the other computer>
    Well, you probably knew the command. Anyways..

    This has happened to me a LOT and every time I found it was something stupid I overlooked. Sometimes an option in my SSH/telnet program, sometimes a setting that I set, and sometimes network latency.

    Hmm. Maybe you should try another telnet program? I only noticed the delay problem when I was using the telnet program included with Windows. It may be a coincidence as the only telnet program I used with one host that was giving me timeouts was that MS one.

    At first I thought it was a trick to deter [D]DoS'ing, but in fact it's not because you could just have 1 million computers connect at the same time and then the machine would be DoSed in 90 seconds.

    I'm really clueless as to why this happens...

    I tried to use Netterm to telnet into my server but the same problem still exist. But I have no problem to telnet into RedHat Linux 6.2. Is it RedHat Linux 6.0 problem?

    Now that I think of it, you may be 100% right. My host's server used Red Hat 6.0 and there was a delay. I use Mandrake and Debian at home and there is no delay but when I used RH 6.0 there was (this is all over a LAN).

    I think you've pinpointed the problem.

    What other way to telnet into a machine is there that is natively supported on both client and server? I'm intrigued and if you have software/drivers/tutorials please post 'em!!
