I have an IPS 4255 which i'm trying to login into via console, but without any luck. I'm sure that I'm typing the username/password correctly as been managing it over than a year, after I gave up, I tried to recover the password and to reset it to the default (cisco) and used the username/password "cisco" after the reboot but my attempts did not meet with any success. The IPS is running version 7.0(x).
Could it be possible that the reason that's its not allowing me to login is due to low memory on the IPS appliance? I remember the last time I logged in it did not allow me to edit any settings and mentioned something about low memory due to Anomaly detection files.
If you did not please try to follow the above to reset the password back to the default (cisco). If the above still does not work you may want to look at reimaging the sensor. Be aware though that a reimage will require you to configure the IPS from the beginning.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
