Re: [Fab-user] hanging problem of a command when executing via fabric

[Nico Mandery]

Hi Rama,

from the name of the command I guess you are trying to launch a webserver
on the remote machine. Are you sure it daemonizes correctly? Does it keep running when
you start it manually and then close the console to the server?

Maybe it is still attached to the console. In this case you propably want to have a
look at the "disown" command:

Hi  Nico,

It is running fine if i use 

sudo("suwww", shell=False)

but command is  still getting hanged when i run via fabric.

after some search in google i find one post on how to resolve this problem

http://agiletesting.blogspot.com/2010/03/getting-past-hung-remote-processes-in.html

even after doing the changes to operations.py as mentioned in the above blog post,  still the above command is getting hanged when i run it via fabric.

No clue what is going wrong.

Thanks

Hi Rama,

   

Seems you only got permissions to run a few commands with sudo and not

everything. fabirics

sudo tries to spawn a new shell per default, and you got no permission

for that.

sudo("suwww", shell=False)

should work

Regards,

Nico

Have you tried sudo("suwww") instead of run("sudo suwww") ?
