Hi guys,

I'm newbie around networking, I have a question:

what I want is to telnet a specific IP/server, let us say 192.168.128.1

then, I try

$telnet 192.168.128.1

Trying...

and that's all.. I never get connected

one of my friends made some script that "fixes" it, AFTER running it I was able to connect to the server using

$telnet 192.168.128.1
$ user:

unfortunately I lost that script, so I'm here requesting your help. Reading my old notes, I remember that the script performed some modification to the entries listed by ifconfig -a, I also have the ifconfig's output (copy & paste)

$ ifconfig -a 
adapter0: 

flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
                inet 192.168.128.150 netmask 0xffffff00 broadcast 192.168.128.255
                 tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0 

adapter1: flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
                inet 192.168.251.150 netmask 0xffffff00 broadcast
192.168.251.255
                 tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0  adapter2:

flags=5e080863,c0<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,CHECKSUM_OFFLOAD(ACTIVE),PSEG,LARGESEND,CHAIN>
                inet 192.168.250.150 netmask 0xffffff00 broadcast 192.168.250.255
                 tcp_sendspace 131072 tcp_recvspace 65536 rfc1323 0 
lo0: flags=e08084b<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT>
                inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
                inet6 ::1/0
                 tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

more than commands, I'm looking for some explanation why does "adding/changing" those entries enables me to connect to the server. I do not see the server ip (i.e 192.168.128.1) listed above.

thanks
