Joining the network


 

All,

Trying to get my Cisco 2600 working. ?I put in some X.25 routing rules as:

x25 routing
x25 route 752 xot 24.22.130.236 (my Cisco does not understand x25 route ... dns)?
x25 route 242 xot 216.239.32.21

If I then do:

x28
call 75241001

It sends packets but gets no response. ?I see in Packet capture:

14:51:24.542896 IP 104.58.86.73.11021 > 24.22.130.236.1998: Flags [S], seq 599537706, win 4128, options [mss 536], length 0
14:51:26.541877 IP 104.58.86.73.11021 > 24.22.130.236.1998: Flags [S], seq 599537706, win 4128, options [mss 536], length 0

DNS notes:

?Lab-Router(config)#x25 route (...)(...).. xot ?
? A.B.C.D ?Address of remote XOT host

However reversing the logic gives me:

Non-authoritative answer:
410.752.x25.org canonical name = 5fc5.ddns.net.
Name: 5fc5.ddns.net
Address: 24.22.130.236

So I assume I am right and its trying to connect, but per the notes this might be down. ?I will try to get a gateway external accessible once I have figured out how to make X.25 work in RSX11M.


 

Ok that looks great! I just turned on the router and PAD, calls to
752.410.0x should connect now.

I have nothing plugged into the PAD at the moment so you won't get
much interesting out of it, sorry <g>

Looks good:

Lab-Router>x28
?
*call 75241001

TCP/IP:

?
15:24:59.736888 IP 104.58.86.73.11024 > 24.22.130.236.1998: Flags [S], seq 2614732411, win 4128, options [mss 536], length 0

15:24:59.818055 IP 104.58.86.73.11024 > 24.22.130.236.1998: Flags [.], ack 1, win 8192, length 0

So it's now getting connected, as you say nothing on the other end.

I am looking at my side to see what I can do to hook one of my old DECs which are meant to support X.25 VT services, to this. When I get back to the US, I can look to update this router to Enterprise, which opens up the translate command; with that I might be able to avoid having the Dec speak X.25, and it should be possible to simply "call" into the Cisco and that translates onto the DEC over IP. ?That seems less fun,..
