Syslog Messages - Read from socket failed: Connection reset by peer

  • 1.  Syslog Messages - Read from socket failed: Connection reset by peer

    Posted Mar 13, 2017 03:12 AM

    Hi

    Was hoping to get some insight as to what these messages mean  - I am seeing them on my Syslog server coming from my Aruba Controller - the messages tend to repeat multiple times.
    The messages appear all related to SSH - is this perhaps a something trying to login and can't?
    Model: 3600
    Firmware: 6.4.4.6

    Are you the only one that can SSH into your controller?  It looks like a misconfigured SSH client.

    Hi

    Yes I am able to SSH to the device - me and my coleague has SSH access.
    Judging from the time stamps it is all during our none workling hours.

    I am suspecting our Monitoring system maybe trying to connect for Config backup - however we haven't seen errors that it fails - but worth looking at I guess.
