Yes, he is asking you to pay for your copy downloaded from his site. This is allowed under the GPL. Once you have a copy then you have the full GPLv2 rights to give your copy away. But note the obligation to supply source code is on you, not on them, if you follow this path. > As it happens I'm not looking to use it for commercial use, but it seems > odd that it's restricted this way. I think it is the presentation of the restriction that is odd not the behaviour. e.g. Putting this presentation on the site with the licensing details. Redhat subscriptions cover getting updates to GPLv2 software (amongst other bits, and other free software). Centos is basically someone giving their copy of Redhat's distribution away by using those freedoms. The odd bit is the free for non-commercial use. So you can download it as yourself, decide it does what your company wants and sell your copy to your company that is interested in it. e.g. You could become the equivalent of Centos. Hopefully people will just pay up if they want it for commercial use. If he removed the "GPLv2" reference from the website, and included a note saying "Parts of this software are distributed under the GPLv2" in the CD case he sends you when you pay for it like some Cisco routers, would you think it odd? -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/listfaq
