ASA5505 telnet/ssh/web issue

jasonchristophercobb — Fri, 21 Feb 2020 12:43:07 GMT

I'm unable to access this ASA from anywhere except console.

I'm no ASA expert, but I've compared it to other ASA's I've configured, and I just can't find the error of my ways.

This is should be easy, I just need a different set of eyes looking at it now. I hope I didn't censor it too much, but I imagine if I'm able to SSH locally, that will fix all the other access issues I have.

The relevant part to control from where you are allowed to SSH into the ASA are these lines:

ssh 0.0.0.0 0.0.0.0 inside

ssh 0.0.0.0 0.0.0.0 outside

But do you have public/private keys generated?

asa(config)# crypto key generate rsa general-keys modulus 2048

ASA5505 telnet/ssh/web issue

jasonchristophercobb — Fri, 24 Aug 2012 14:02:17 GMT

Great thanks. I guess all the other ASA's I've configured have been used before.

That fixed the SSH part, but not the access through ADSM or CCP.

The ADSM says 'Not IDM' in the Java window.

IE asks me if it's a trusted site, asks for login ID but then says webpage cannot be found.

do you have the file asdm-621.bin in flash?

I've verified that the asdm .bin is there, many times... but I guess it helps if you make sure you are refering to the same version that is stored in flash.

It's always the obvious that stumps me.

These are always the hardest to find ...
