Dear All,

I have a problem with my RB450g , ie can not ping the hostname with the following error:

[admin@ge-01.xxx.net] > ping www.yahoo.com
invalid value for argument address


but the client can ping the hostname

note:
ip dns 202.129.189.59
ip dns 202.129.189.61
I also tried google dns 8.8.8.8 but still the same result

regards
saktie

Can you ping the dns server ips?

Can you ping the dns server ips?

sure

The client is using the same dns server ips? Can you post "/ip dns print"?

ip dns pr
servers: 202.129.189.59,8.8.8.8
allow-remote-requests: yes
max-udp-packet-size: 512
cache-size: 5096KiB
cache-max-ttl: 1w
cache-used: 25KiB

the last configuration

If you use the CLI, use this at a prompt:
:put [:resolve www.yahoo.com]

You should get an ip address.
What version RouterOS are you using?
