  1. Netcat Problems

    Whenever I try to connect to my web server using the following
    command:

    nc -v XXX.XXX.XXX.XXX 80

    I get the following result:

    nc: forward host lookup failed: h_errno 11001: HOST_NOT_FOUND

    I don't get it. Is netcat trying to lookup an IP address when I've
    already supplied one? Also, very very infrequently, the connection
    succeeds, so I know that my syntax is correct, but 99% of the time
    this is the error message I get. This seems to be the simplest of
    netcat commands, and I can't get off of the ground even with this.
    Help!

    Use telnet (without -v) for testing, since netcat has bad error reporting.

    Oh, so that's why ps doesn't work.

    I did this. Telnet works while netcat does not. Any thoughts?

    Netcat will try to resolve an address anyway, except if you use the
    modifier -n, RTFM or nc -h ;-)
    A lot of tools have the same behaviour.
