Hi everyone!
There seems to be an error with my ntalkd recently. Whenever someone would
want to 'talk' to someone on localhost, he/she gets the message
[No connection yet]
[Error on write to talk daemon : Permission denied (13)]
and the talk program quits. I checked, and it seems that the following ipfw
rule was causing it:
00200 deny ip from any to 127.0.0.0/8
which is weird since that rule is a default from within /etc/rc.firewall.
When I remove this rule, I would instead get the following:
[No connection yet]
[Checking for invitation on caller's machine]
[Checking for invitation on caller's machine]
.
.
The thing is, talkd seemed to work fine before. But lately, many other weird
things have been happening. An increase in incoming traffic would sometimes
cause the box to shutdown most vital internet daemons, plus delete certain
lib files like mm (for apache) and tcl. Looks to me like the box has been
breached, but I've checked all the advisories and all seem to have been
taken care off. Anyhow, I'll paste some of the configuration that might be
causing these below, and hopefully there's someone out there who can help!
Thanks all. :)
Regards, Rudy.
