We have a Dell FX2 with dual IOA cards in the back that have 10 gig uplinks (one for storage network, one trunk to regular network).
We set a root password but recently on an internal vulnerability test it came back with an "F" rating for easily guessable SSH credentials - successfully logged in with username: root password: calvin.
The thing is I did try this and got in but the connection dropped right away. I've never had stability using Putty to SSH directly to the IOA. I've always had to use Putty to the CMC and then use command to select that IOA switch and basically utilize the CMC as a proxy.
If anyone knows why putty only seems to stay connected when proxied through the CMC, and if anyone knows why the default root/calvin credentials still authenticate when we changed the root password, please let me know. Thanks!
