[logback-user] SocketAppender Public IP

[Ross Sargant]

That has more to do with your networking & firewall configuration then
logback.   Logback is probably blocking when it tries to establish the
connection to <remote server ip>.  <remote server ip> is neither granting
nor denying the connection.

Try testing out the TCP connectivity to the remote logback server outside
of logback  (*telnet <remote server ip> 6000*)  from the same machine you
are experiencing this issue.  If that doesn't work, logback can't be
expected to work either and you'd need to work out the networking/firewall
issues before worrying about logback.
