Hi Josh, I'm running on a linux64 system. If I enter the suggested command I simply get: hostname| No spaces before or after the name.
In other programming languages these spaces don't appear if I use their respective functions for getting the host name. Maybe my idea of writing "Runtime.getName()" wasn't correct? I just guessed this one. bye Zitat von Josh Milthorpe <josh.miltho...@gmail.com>: > Hi Michael, > > for Native X10, Runtime.getName() uses the value returned by gethostname(). > This should be null-terminated: > > http://pubs.opengroup.org/onlinepubs/009695399/functions/gethostname.html > > However, it looks like for your system, there are a number of spaces in the > hostname before the null character.
