For tftp access though, wouldn't he not need a tftp server?

Type "reload" at the router prompt and then type "show running-config" and tell us if it goes back to the reverted settings.

not going to work if it's only booting to rommon> prompt...

tftp program really just need installing and putting the file in their shared dir. shouldnt have any authentication on it

indeed it doesn't even support authentication, making sure the firewall is off is the only obvious thing that occurs to me

sorry guys, but i just can't get my head around this tftp hosting thing.

about the firewall, i think the router firewall is still blocking a little as opposed to completely stealthing ports, should i connect my modem directly to the computer and just have the console cable hooked upto the router? im going through the router still atm.

"reload" command in rommon is "reset" i believe

 

[bigredshark]

or indeed boot will do the job if there's an image there, but if you ended up there with out doing control-break then it's not much help...

 

[mmj_uk]

just did reset command and router rebooted:

monitor: command "show" not found

 

[bigredshark]

just did reset command and router rebooted:

no, it won't, that suggestion is useless in this scenario. just reload the IOS from tftp and see where that leaves you.

 

[mmj_uk]

im trying, but im stuck at the tftp_file stage, it thinks im trying to enter a command and complains. yes im very about what im doing.

 

[bigredshark]

you're doing tftp_file=c2600-ios11-3.bin (obviously a different filename)??

 

[mmj_uk]

progress so far, can someone please point me in the right direction.

should the first ip address be of what my router should be?

 

[mmj_uk]

i tried ip address with 10.10.10.1 and same thing, illegal ip address message.

 

[bigredshark]

quickly do a 'set' and post the results??

and also, which interface do you have connected??

i've now just got router hooked up via console cable to com port and modem straight to pc so i know firewall is not interfering.

 

[bigredshark]

Ok, I've just done this on a 2610, make sure you boot it cleanly and enter these in this order and before anything else

it's won't affect IP addressing like this but tftp is transfered over the network, not the console lead

 

[mmj_uk]

ok im going through router again now, will try your thing above in a sec.

 

[mmj_uk]

illegal ip address again... are those the exact settings i should've used or just examples? the only one i changed was file name.

maybe i am using tftpd wrongly?

 

[bigredshark]

no, those are examples, you'll need to put in your own, i don't know, as you can see it worked for me, though i had to do a clean boot before it would.

it's not the tftp server, it's the router complaining about the IP you've tried to assign in.

puzzleing...

 

[mmj_uk]

when i did a dir flash: there were still a few files laying around, maybe they are causing problems can i wipe them?
