telnet log messages

[ckyun]

Hi,

I have FAS3240A . I saw some message log about telnet i think .

[FAS3240A1-L: pac.peer.getName:info]: telnet: getpeername() failed in protocol access control with Socket is not connected.

[FAS3240A1-L: telnetd:warning]: Failed Login from Unknown, IP address 0.0.0.0.

I don't know what it means.

Telnet is working well now but this log occur repeatedly .

What can i do ?

Check attached message. 

Check if you have any cluster or vserver peer which is not available any more.

I have already searched for this log but it didn't help me i think .

Thanks for your advice.
