IP range probing?

[Brink]

just a quick general question:

I have a nortel VPN switch that I'd like to test, although I don't know it's LAN ip to connect to. Is there any way I can probe multiple ip ranges? (all privates for starters)

TIA

[Gertrude]

Sometimes with certain equipment when it powers up it will send out some broadcast traffic that will show its IP. So if you had a computer running a packet sniffer on a hub you may be able to get it.


You could also try to ping 255.255.255.255


Nmap is also a option..

nmap 192.168.0.1-255

Wll scan all IPs in the 192.168.0.X subnet



If there is a console port on it you could use minicom or hyper terminal, and try to connect to it.

[Brink]

yea, the console port is a custom pinout and I don't have the cable they originally supplied, so it's unlikely I'll be able to get into the console. I guess there's no software that will automate scanning (and change interface address incrementally)

btw it's a Contivity Extranet 1500 Series

#!/bin/bash
for i in `seq 0 255`
do
ifconfig eth0 192.168.i.1 netmask 255.255.255.0
for j in `seq 2 255`
do
ping 192.168.i.j
done
done


Unless the IP of the device is a foo.foo.foo.1 then that should check everything on the 192.168.x.x series of addresses... modify as needed for all the other private subnets (10.0.0.0/8, 172.16.0.0/16, etc)

Also, does this help?

Looks to be the manual for the device...

[Brink]

Thanks Ph34r, I'll try your little script

I do have the manual printed out (probably from that same pdf) but it's not entirely helpful in the event you don't have everything they originally provided (serial cable, novell startup disk, etc) and these tools are pretty hard to find online it seems.

I'm trying to get past their registration process now...all this for some "server software" which sounds pretty vague to me.

update- and yes, I can't get the software because I need a service contract with Nortel (which isn't about to happen)

[Gertrude]

You could wire your own console cable for that if you had to. I looked though the manual and it shows what the pinout is (Table 3-1).

[Brink]

yea, that's the only real sane way of accomplishing anything, but I doubt I have the materials here.

[EnigmaOne]

Page 3-8 (Table 3-3 and accompanying text) gives you everything you need to know to wire up a standard serial cross-over cable for console access to the switch.

They say to see page 4-2 for details....4-1 is worth a look as well, if that's the case.

[edit]
Oh yeah. Give this HOWTO a read-through:

Wow, I forgot about that thread, let alone anyone would actually track me down to anwser it, thanks =)
