John, I would think any 4.x version would work but the one you downloaded is not the latest. http://ftp.gnu.org/gnu/bash/bash-4.3.30.tar.gz or ftp://ftp.cwru.edu/pub/bash/bash-4.3.tar.gz is listed as the latest version. 73 Doug WA3DSP http://www.crompton.com/hamradio Date: Wed, 19 Aug 2015 12:13:49 +0000 From: izzy_y2k@yahoo.com To: app_rpt-users@ohnosec.org Subject: Re: [App_rpt-users] modified custom nodenames I am a total noob at linux but managed to do the following: 1. downloaded bash-4.1.tar.gz and placed in the root directory2. tar -xzf bash4.1.tar.gz cd bash-4.1 ./configure make sudo make install 3.
