[Swift-devel] hostname returns none in Surveyor

[Emalayan Vairavanathan]

Hi All,

I am trying to run some experiments in Surveyor. The software I am using gets the IP-address of compute-nodes using hostname command. 

With zepto-vn-eval/mosatest profile hostname command returns none.
But with zeptoos profile hostname returns the correct IP address. 

Is this due to some configuration issues  in zepto-vn-eval/mosatest profile?As a workaround I tired to use ifconfig with both profiles, but it seems ifconfig is not returning the correct IP address. 


Is there any command / files which I can used to retrieve the hostname on compute nodes? I have pasted the console output with both profiles below. Please let me know if you need more details.


Thank you
Emalayan
