sockets
What
The socket command doesn’t display sockets for people who didn’t have entered their name yet.
Patch
In act_wiz.c/do_socket(), replace
if ( d->character != NULL && can_see( ch, d->character )
&& (arg[0] == '\0' || is_name(arg,d->character->name)
|| (d->original && is_name(arg,d->original->name))))
{with
if (d->character==NULL) {
sprintf( buf+strlen(buf) ,"[%3d %2d] nobody yet@%s\n\r",
d->descriptor,
d->connected,
d->host
);
} else if ( d->character != NULL && can_see( ch, d->character )
&& (arg[0] == '\0' || is_name(arg,d->character->name)
|| (d->original && is_name(arg,d->original->name))))
{New output
none > sock
[ 8 1] nobody yet@gw-nl2.philips.com
[ 7 0] MavEtJu@gw-nl2.philips.com

logging
Log much much more regarding networking. Log when somebody makes a tcp-connection, log when somebody enters an invalid name, an invalid password, log when somebody tries to login while he’s online, log when somebody disconnects. Use wiznet to display all information.
dnslock
NOTE!
This is one solution, a better solution can be found on the snippet page.
What
If your DNS server is acting wierd (broken, slow…) and a new user logs in, the mud will freeze for about 45 seconds. In the mean time, the user has logged off and on again, causing another freeze and if this is repeated multiple times nobody will like it anymore.
Solution
Implement a function like dnslock which prevents reverse DNS lookups.
Patch
In comm.c/init_descriptor(), replace:
from = gethostbyaddr( (char *) &sock.sin_addr,
sizeof(sock.sin_addr), AF_INET );with
if (!mud_status.dnslock)
from = gethostbyaddr( (char *) &sock.sin_addr,
sizeof(sock.sin_addr), AF_INET );
else
from=NULL;
dnew->host = str_dup( from ? from->h_name : buf );
