put in subshell. something like this will make things more clear:

(ssh xxxx arp -an) | grep lanx > /tmp/lanx

ideally just put the commands in quotes like this:

ssh [email protected] '/sbin/arp -an | grep lanx' > lanx

or

ssh [email protected] '/sbin/arp -an' | grep lanx > lanx

The other problem might be the user admin on your machine does not have arp in PATH (is he root? arp is usually in /sbin/ and /sbin/ is usually not in PATH of a regular user.
