I'm trying to get CitrixICAClient and CitrixXenAppPlugin working on Ubuntu 11.10 64bit.

I've pretty much got it all working (I've set it up before OK on Windows), except when the Secure Application Manager launches it displays an error saying "You do not have permission to change the hosts file. Please verify that you have write permissions in the /etc directory."

Now obviously my user does not have access to modify files in /etc and the solution seems pretty obvious to me - give my user write access, but I don't feel comfortable doing that.

I've tried "sudo chmod 666 /etc/hosts*" but the error persists, I'm not sure exactly what it's trying to do or whether I need to change the permission on /etc too.

Appreciate this issue may be a bit niche, can't seem to find any info on it online, has anyone come across any situations similar to this before?

Many thanks.
