arp entry deleted for the server

[T G Manikandan]

Hello,
I have deleted the arp entry for the Hp server.
How can I recreate it.
Unfortunately I used arp -D hostname.
I am unable to connect remotely.
Please help me to solve the problem.
This is urgent.

Thanks.

You add an arp entry just like deleting one.
>/usr/sbin/arp -s $HOST $MAC
I would actually recommend that if anything changes frequently on the network. I.E. DHCP hosts with dynamic pooling and the $HOST is among them, use
>/usr/sbin/arp -s $HOST $MAC temp

If you delete the arp entry for a host, then try to talk to the host via any network protocol, then the entry should be re-created for you!

>/usr/sbin/arp -a
will show you your complete routing table.

Regards,
Shannon

Hi,
Use the following command to recreate the entry.

"arp -s hostname hw_address [temp] [pub] "

Good luck.

Hello,
I just found out the MAC address from one of the other servers by using arp -a.
Now I have done a arp -s MAC_address.Will that be ok?
Thanks for your immediate response.

Thanks.

Hello,
I just gave the hw_address.
The hardware address for the server was 0:10:83:7c:.....
So I just gave arp -s 0:10:83:..
Is that ok.

Thanks

How can I find out this hw_address on the console.
Thanks
