By the way I had a lot of strange behavior trying to get my BBB running yesterday. I guess I need to try to look at the logs. It didn't seem to always boot up cleanly. Sometimes I'm not getting a webpage and when that happens the board seems to always have 2 blue lights on solid instead of flashing like normal. I was using that IPScan program and it seemed like it kept wanting to grab a different IP address. It was bouncing between 2 different IP addresses and I swear sometimes both IP addresses were showing up in IPScan. Sometimes the name was FPP and sometimes FPP-4 and sometimes both were there. I had one time when I was able to control the lights but the webpage wouldn't serve up. It was driving me crazy.
I saw this sort of behavior as well. it started when I moved from master to stage, and I couldn't get it resolved until i reimaged the bbb.
i originally had the ethernet nic configured for 192.168.1.114 ... it no longer responded on that ip, and ipscan told me it had 192.168.1.11 -AND- 192.168.1.13.
rebooting didn't help. BOTH of those addresses were reachable with ssh and ping. ifconfig showed 192.168.1.11. the fp config file showed 192.168.1.114
the /etc/hosts file didn't have the hostname updated. I had used "FPP-P10A". The command prompt was messed up too... fpp sometimes... and fppp10a other times.
i thought my router/switch might have gotten confused with its arp table.
anyway, no problems after reimaging.
