Hi,

I opened up a terminal on my Macbook and was surprised by the prompt. It comes up as
"jehan:/ warrentegner$". What is the 'jehan' for? Jehan is another Mac user in the building.

Can anyone tell me what the 'jehan' is doing there and if my system is being accessed?

Regards, Warren.
 
It's actually a quirk in networking between the Mac and Windows DHCP servers. I get it all the time at work. I'm not sure of the details, but essentially the DHCP box gets confused by the Mac and give it a hostname that's in its cache, hence you get someone else's name.
 
Like I said, I don't know the details. It's the netbios name it gets, as far as I know. Trust me, it's pretty random (I guess if you all have static IP addresses you'll only see one name) - doesn't mean anyone logged into your box. If you want to see if anyone actually logged into your machine, type 'last'
 
guy.. the only way you'll get that on your prompt is if you are logged in as that user. ie. su jehan

check if the user exists locally : id jehan
and if so... lol... get rid of him: userdel jehan
 
whoops.. userdel is linux.. cannot remember bsd command...
 
Thanks for the help guys.

koffiejunkie: I typed 'last' and it returns no results. Good sign.

The_Librarian: Your DNS comment makes sense. I did change my IP this morning. But, I should then be able to ping 'jehan' then.
