Does anyone know what to make of the "LAST_ACK" in the output of netstat?
# netstat
Active Internet connections
Proto Recv-Q Send-Q Local Address Foreign Address
(state)
tcp4 0 0 companyname.company.8765 123.456.789......
LAST_ACK
where 8765 is the port number.
Our shopping website was non-functional while the LAST_ACK state persisted.
Upon waiting a few minutes, the following change occurred without any
intervention on our part (which allowed the site to function normally once
again):
# netstat
Active Internet connections
Proto Recv-Q Send-Q Local Address Foreign Address
(state)
tcp4 0 0 companyname.company.8765 *.*
LISTEN
tcp4 0 0 companyname.company.8766 *.*
LISTEN
man netstat did not have anything useful (based on a quick review) that
would explain how to interpret the (state) messages.
TIA
Vipin
