Address 18.104.22.168 maps to 10.152.71.61.in-addr.arpa, but this
does not map back to the address - POSSIBLE BREAKIN ATTEMPT!
I just got this when logging in to my Slackware box from my campus wifi (first time I've used the campus wifi, new system). Could that be the culprit?
PS 22.214.171.124 is the address of my server as reported by ifconfig | grep ppp0.
