From time to time, I've encountered issues with OS X clients' network connections (Wired and Wireless, Leopard/Snow Leopard) where nothing will fix the issue, until you reboot.
- Is there a particular 'network service/process' I should be watching out for?
- I was thinking it would be useful to know of a command that will reset a 'network connection' type service/process (same as running a sudo /etc/init.d/networking restart).
After basic troubleshooting such as DHCP, DNS, checking for interface malfunction (disable/enable), checking logs and not finding enough helpful info, sometimes when everything else fails the best thing is just to reboot the machine. I'm not sure what all the 'init.d/networking restart' does in Linux, but I know it's way more helpful than disabling and enabling interfaces.
