[arm-allstar] Login password changed automatically

[dklortie at teksavvy.com]

Hi all,

I am wondering if anyone else has experienced this issue and have a recommendation on how to fix it.


I have 5 all-star nodes set up running on 3 raspberry pi 3's.  One is connected directly to a repeater as a controller, 2 are used for remote link to 2 of our repeater sites that don't have internet and 2 are 440 simplex nodes for local fill in.  All are linked permanently as to provide coverage for our club members.


About 6 months ago I went to do an update on the pi running as a repeater controller at the one site, and tried to log in via SSH through PUTTY as I have done in the past.  However, I would put in the user name of root and the password (yes changed from the default of root), and it said password invalid and prompted me for the password again.


I reinstalled the image and set the pi back up from scratch and all has been good.  Everything working great. Login works fine.


Fast forward to present and I have had one of our club members who is hosting one of the pi's as a repeater link and simplex node at his qth.  He received a message from his ISP that a computer on his network is participating in a DDOS attack to his neighbors.  When I tried to log into the pi at that location to do some investigation and I got the same problem as 6 months ago, but on the second pi not the original.  Try to log in and keeps asking for password.  I could still log into the other 2 servers no problem.  


Today I tried to log into the other 2 servers and now they too keep asking me for the password over and over.  I have not changed the passwords.


All of the servers were using the same root password which was changed when they were set up so I know it's not that I am losing my memory and forgot the password.


Has anyone seen this before and if so how was it fixed.  If not, how do I keep this from happening again. It is a pain to have to keep setting the 5 nodes and 3 servers up constantly.
