DNS, routing table

[bcme10]

Does anyone know how to quickly refresh the routing tables on SOLARIS? Basically, the networking guys screwed up and pointed our application server hostname to the wrong IP address. Now the web server is constatnly hitting that wrong address even after the networking group corrected the entry. I know a reboot of the box would clear it up but is there anything I can do whitout rebooting?

thx

route -f

Then activate /etc/defaultrouter

HTH.

Thx,

I did the route -f, that flushes the gateways from my routing table. I had to manually add the default route back into the routing table.

Good. I assume your box will automatically pick up the default when it next reboots?

 

[bcme10]

yes it will.

Does Solaris cache Hostname/IP addresses? Or does it query the name server everytime to look up the IP address of a hostname?

My web server is still going to the wrong IP address. In windows you can issue a ipconfig /flushdns, is there a similar command in Solaris?

Thx again.

yes, Solaris caches DNS info; I suggest to stop nameservice cache daemon with
/etc/init.d/nscd stop

run a
ping -s webservername
check if the IP Adress is now correct

You can add an IP Adress to your /etc/hosts file and change /etc/nsswitch.conf to:
...
hosts: files dns
...
