Q. My server doesn't want to connect to uplink or is connecting to
another uplink while one is connected already. Where am I wrong?
A. Pay your tightest attention to connection clases. All upstream
links MUST be gathered in one class (say, 1), and there MUST be
MaxLinks set to 1 in that class. All downstream links MUST NOT be
in that class, but some another. You MAY use autoconnect to
downstreams, it doesn't matter here.
NOTE: if you use any services like tkserv (S: line), it MUST NOT
be in upstream class, otherwise your autoconnect will be broken.

Q. How could I prefer one uplink to another?
A. Place administrative preference (integer) the next parameter
right after class number in your c/C: line. The higher number,
the greater preference.
NOTE: this is RusNet IRCd feature only.

Q. How could I K:line some nick or nick pattern?
A. Place the nick into "ident" field of K:line. Of course, such an ident
will be killed, too.
NOTE: this is again RusNet IRCd feature only.

Q. What is the difference between /quote RESTART command and actual server 
restart by killing ircd process?
A. /quote RESTART flushes all send buffers and closes all active connections
exactly as process kill (catching SIGINT) does. But in case of RESTART command
ircd process performs execv and respawing itself (not by external wrapper!) 
keeping back the same PPID but loading the new code from disk. RESTART command 
is much more fast than simple restart.

Q. After upgrade my server stopped resolving some hostnames and my clients
appear on the net with naked IP numbers. Why?
A. #define RESTRICT_HOSTNAMES has been added to config.h. It requires
strict hostname compliance with RFC. If for example given hostname contains 
the underscore symbol "_" (most popular problem) or otherwise breaks RFC 
requirements hostname will not resolve.

Q. How could I possibly define custom client flood setting for our very
special Quiz bot?
A. Look at doc/example.conf for i/I:lines configuration. RusNet extensions
offer an extra argument within these lines which is exactly what you need.
