I rebuilt my hard disk with Diskwarrior the other day as I was having some problems.

Diskwarrior "rescued" the following files - does my OS X installation need them, and how can I restore them if I need to?

The files were:

resolv.conf 4KB
ntpd.pid 0KB
pppconfd 4KB
syslog 0KB
syslog.pid 4KB
utmp 0KB

Everything seems to work OK - but I don't want my machine to become a security risk.

Any ideas would be great! Should I reinstall OS X?

BTW, running OS X 10.2.4 (updated from 10.2.3 this (Friday) morning).

Hope this helps. From my machine running 10.2.4

/private/etc/resolv.conf
/private/var/run/resolv.conf

/private/var/run/ntpd.pid


pppconfd -- couldn't find it

/private/var/run/syslog
/private/var/run/syslog.pid

/private/var/run/utmp

Thanks - but are these files necessary - I'm assuming the rescued files are incomplete - so replacing them might make the system unstable.

The /private/etc/resolv.conf file you should probably replace. The stuff in /var/run should be automatically generated by the system, so you probably don't need to replace that stuff.

Cheers! what does resolv.conf do - and if it is only 4KB is the "rescued" version incomplete?

Yes, all files you listed are in /var/run except for /etc/resolv.conf which is a link to /var/run/resolv.conf, so you'd need to type "ln -s /var/run/resolv.conf /etc/resolv.conf" to rebuild it, and then I'd reboot to have the others automatically created again.

Thanks - but what is it, and what does it do?

[Moonray]

/var/run/resolv.conf contains the nameserver IP addresses and gets written each time you connect to the internet. Because it is a 'variable' file, it lives in /var/run.

/etc/resolv.conf is the link to it in a fixed/static file and should be used whenever that information is needed (regardless to what it points).

Cheers - thanks all for you help.
