Hi,

Its 5:26 AM lol... after 6+ hours NONE stop research on how to fix putty on GNS3 as it was opening and closing after a few second.. and couldnt find a SINGLE article ANYWHERE,, i started doing my own research and thinking,

( Teraterm Pro worked fine but putty wasnt, and im a big fan of putty so ... hey :P i got to make it work and be a happy user ) lol

anyway a very simple idea kicked in my head, when i looked at the 'Terminal Command'

C:\Program Files\Putty\putty.exe -telnet %h %p
( C:\Program Files\Putty\putty.exe is my putty directory, you can put it any where i guess )

and for some strainge reasons my pc is getting localhost and 127.0.0.1 not the same, which should be..
and %h is the host ( which will use localhost ) and not 127.0.0.1 ( we want 127.0.0.1 )

so just simply replace %h with 127.0.0.1

C:\Program Files\Putty\putty.exe -telnet 127.0.0.1 %p

And you are good to go... worked for me, but close any other console as it wont abviously open 2 or more at the same time, 1 for each router.

Im using Windows Vista, but it should work for any other windows OS i guess.. I hope it helped you..

P.S i just done another check to see why it wont accept localhost but 127.0.0.1, and on my pc localhost is looking up my ipv6 ip, which i forgot to disable on my wireless, and 127.0.0.1 is looking up my ipv4 which im using now.. ( i checked by pinging, ) you see that localhost will get resolved to a ipv6 sort of thing...


Good Luck,

Putty I love you lol..

Kudos to you Dracula_!

It works...for PuTTy anyway--I had to alter for MY path which is:

C:\Program Files (x86)\PuTTY\putty.exe -telnet 127.0.0.1 %p

but this comes up, responds and I have access...there still seems to be a kink with the 2600s, so I'm running with 36xx now...

I tried securecrt and it did not work, though that's trivial for me at this point--

Again, well done and thank you for your work on this-

You might want to ask the mods to sticky your post as there have been a few posts about this-

covkid-

yes i just registered on this forum just to post this thread lol as i dont think any where on the web has this info..

well another thing that it should make it work, without hacing to change the %h is to disable ipv6 from your network card from networks in control panel,, right click, properties on your wireless adaptor or what ever you are using and remove the tick from ipv6,

I HAVNT tired this,, but im guessing it would work ...

and yes not a bad idea to sticky this..

Thanks Dracula_. Good job
I have been trying endlessly with console windows closes in a sec. I found your post and registered to say you thank you. Putty just worked great for me in GNS3 as per 127.0.0.1 instead for localhost. I guess lot of ppl has this problem in vista. This is the right solution. keep it up dracula_

Hi,

In windows static DNS entrys is stored in following text file:


And here is content (Vista):


It show that 127.0.0.1 (address) is binded to localhost (name) in my case.

It would be nice to see this file in your case.

Alright I give up.!!

Been trying to get putty running but all in vain!

I am hoping one of you gentlemen can help me out here :)

Basically I am new to this GNS3 thing, trying to run a simple lab where I am connecting 3 Routers.
So when i try to start the putty session for R1,works great...perfect..i have full access to my router(7200)
But when i start or try to start the putty session for R2 and R3 ,I get a putty window but doesnt response.It just stays there with 127.0.0.1:Putty written.
I did put the loopback address 127.0.0.1 instead of %h but still running into this issue!

could it be related to the IOS image im running??(i highly doubt cuz putty works fine if i just run it on R1)
So the problem is I cannot run Putty session when I have more than 1 router involved!
FYI...im using 7200 and image : (C7200-IS-M), Version 12.2(7a)
Also using MS Vista Home Edition.

The same problem I have in windows xp at work and in windows 7 at home, my IOS is c3640-i-mz.124-25d.bin
