No route to host (unreachable from Mac but not from PC)
Hi all,
Short description:
I'm getting a "no route to host" when pinging a server at work (and I'm doing this from home). If I do the same thing with my PC, it returns a response and it can find the server. Both computers are on DHCP, wireless via the Airport Extreme. I'm not using a firewall on any computer and I'm not forwarding any ports on the Airport Extreme. It's all wide open. This USED to work on the Mac and one day it suddenly just would not work! At least that's what I would like to think... 🙂
Long description:
This started a while ago, can't exactly tell when and what I could have done to cause this (or if this was caused by me at all).
One day I was unable to SSH into work like I do quite often from home. Also, VNC did not work (same server). Now the weird thing; I was able to FTP into the server on port 21. The server is also running FTP on another port, however this port was unreachable. I tried doing a ping to the server in the shell but all I got was "no route to host".
Since I am not running a firewall and I'm not using port forwarding (and all of this worked fine using that setup) I was clueless. I booted up my PC and connected it just the same way I do with my Mac; wirelessly and using DHCP through my Airport Extreme.
From the PC I was able to do everything, just like I used to.
I've found out that flushing the DNS cache might do the trick (lookupd -flushcache). This didn't work. I've also tried to do flush the firewall rules (ipfw flush) -- and this did nothing... probably because I'm not even running a firewall.
What should I do?
I hate having to reinstall the whole computer when Leopard is closing in...
