all tcp are CLOSED on SCO Unix on VMWARE

Hi folks,

First of all, sorry about my english, isn't the best and thks for advance.

Here es my problem...

I have virtualize an SCO unix with VMware ESX 3 and everything was going on beatifull until that i try to connect from anorther host, i can't do it so i check the connection with "nmap" from a linux box to the interface of the SCO and it show me that i has all port closed except 8000 tcp, then a go to unix box and run "netstat -an|grep tcp" and show me this:

tcp 0 0 *.80 *.* LISTEN
tcp 0 0 *.* *.* CLOSED
tcp 0 0 *.22 *.* LISTEN
tcp 0 0 *.23 *.* LISTEN
tcp 0 0 *.21 *.* LISTEN
tcp 0 0 *.25 *.* LISTEN
tcp 0 0 *.110 *.* LISTEN
..... and so on..

So a realize that the problem is the "tcp 0 0 *.* CLOSED" because i do a "telnet localhost 80" or "telnet localhost 22" and it connect perfectly.
I try to see if there is a firewall running but as far as i know SCO has't firewall buildin but i trying to search an iptables or ipnat route and there isn't any, i check "netstat -rm" to check routes and is everything ok. The network interface is OK because i can connect to other linux o unix box with ssh and is works sweets.
SO if somebody can tell what is going on or give me a tips i will appreciate so much.
Cheers

tcp-env

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME

       tcp-env - set up TCP-related environment variables

SYNOPSIS

       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]

DESCRIPTION

       The  input  for  tcp-env  must be a TCP connection.  tcp-env finds out information about that connection, puts the information into several
       environment variables as described in tcp-environ(5), and runs program with the given arguments.

       Usually tcp-env is run from inetd.  It might instead be run from another server that already sets up the right  environment  variables;  if
       PROTO  is  set  to  TCP  when  tcp-env  is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
       whether the input is a TCP connection.

OPTIONS

       -r     (Default.)  Attempt to obtain TCPREMOTEINFO from the remote host.

       -R     Do not attempt to obtain TCPREMOTEINFO from the remote host.

       -ttimeout
              Give up on the TCPREMOTEINFO connection attempt after timeout seconds.  Default: 30.
