Again sent earlier. Thanks for the intervening comments about vulnerabiliteis and versions. A lot of issues and suggestions have been made and raised. My brief response is that yes, according to nmap and my intention I had port 23, for ssh (I moved it) and port 5900 open and the rpc port, I think. I'm going by memory. Theoretically the only pinhole in the ISP router firewall was port 23. To use port 5900, you had to use an ssh tunnel. My web server is on another machine. Since I only use it for development, I don't leave it up. My actual web pages are hosted externally on a vendor's box. My experience with the upgrade treadmill is that it is a waste of time. By its own admission (if a concept can have that) the new versions will have issues and you need to upgrade. If the issues with an older version don't affect you, then it is perfectly fine to use it. Why upgrade and risk the fact that the new issues will affect your use case. The developers for Fedora 13 were no smarter or dumber than the developers who are writing Fedora 36. Or pick your distro of choice. The issue with an older release is that nifty new things come out and you can't really use them. But, if you run a VM with a recent version of the distro, you can use them just fine. The other issues is that if you are getting vendor support, they can only reasonably commit to supporting a limited number of versions. This is AMD hardware from '06. -Gary On Fri, Aug 05, 2022 at 06:19:54PM -0700, Rick Moen wrote: > Quoting Brian E.

I asked Tek Systems if they would host a meeting for us and they said that they don't have the capacity currently. Perhaps we ought to do a social like we did in the past? -- Brian Lavender http://www.brie.com/brian/ "There are two ways of constructing a software design.

Re: Firefox crashes

The only thing I found in settings was tracking. I changed it to custom and unchecked everything. It always fails at the login screen. Either before or after I enter my credentials. Other pages work fine. Anyone using Firefox? On Tue, Jul 25, 2023 at 01:01:04PM -0600, Linus Sphinx wrote: > Upgrade to a 64 bit virus. Anything in F12/errors?
