[Devil-linux-develop] presentation :)

[Diego T. <dt...@co...>]

I talked with Heiko about some additions to the devil-linux distro, and he recommend me to join this list and ask for comments, so here it goes:

This has been done, but a few remarks should be made.
dnscache produces a lot of output (for me its ok to have all the messages logged to syslog, but maybe someone finds that there are just too many syslogs entries)
tinydns doesn't have that problem.

when logging with a remote syslog the dnscache daemon, i've found a "deathlock". for each entry on syslog, syslog-ng tries to resolve the host that sends the log. so if you're using dnscache on the box with the syslog-ng server, you'll have to:
a) use_dns(off) on syslog-ng.conf
b) comment out the verbose output of dnscache (requieres modifiying the sources)

how to use syslog-ng with dnscache/tinydns :

/etc/service/dnscache/log# ls
main  run  status  supervise

/etc/service/dnscache/log# cat run
#!/bin/sh
#exec setuidgid dnslog multilog t ./main
exec logger -i -t dnscache

the same for tinydns. just comment out the multilog option and use logger for loggin.
