Re: Monit sending seemily bogus alerts?

[Eric Pailleau]

Hello,
ssh server can limit the number of concurrent connexions.
May be there is already the maximum of connexions while monit
try to test, and is rejected...

regards.

man sshd_config :

 MaxStartups
             Specifies the maximum number of concurrent unauthenticated con-
             nections to the sshd daemon.  Additional connections will be
             dropped until authentication succeeds or the LoginGraceTime
             expires for a connection.  The default is 10.

             Alternatively, random early drop can be enabled by specifying the
             three colon separated values "start:rate:full" (e.g.,
             "10:30:60").  sshd will refuse connection attempts with a proba-
             bility of "rate/100" (30%) if there are currently "start" (10)
             unauthenticated connections.  The probability increases linearly
             and all connection attempts are refused if the number of unau-
             thenticated connections reaches "full" (60).
