Greetings WLUG! Loving the discussion here.. I am wondering if any linux enthusiasts or freelancers would be interested in looking over my shoulder as I am trying to trouble- shoot my linux host? Am a relatively inexperienced enthusiast of the hands-on variety. I could certainly use your advice! Reach me directly on essencenetworks(a)gmail.com and I can send you my Signal details too. To migitage being a bore to the less interested.. I will post only a summary of the problem I am trying to solve. ----------------------------------------------------------------------------------------------------- Problem: After a reboot, my webserver process no longer serves SSL certificates to external browsers. At the client/browser side this command: openssl s_client -connect <<MYSERVERNAME>>:443 -msg reports CONNECTED but there is a handshake failure and so "no peer certificate is available." Now, this was working perfectly. before a re-boot. (I am using a self-signed SSL cert). This probably means that the http server does not permit service on the port. As it was working prior, this is probably not a port-mapping or privilege issue. I suspect that on reboot the DHCP service has messed up host addressing but I could be wrong.Probably VirtualBox etc has something to do with it - well outside my depth! My setup is: I am running the server on my home LAN,.. a VirtualBox VM (CENTOS/OracleLinux) hosted on a local ArchLinux install running on my old Intel Macbookpro. Network setup is Home broadband LAN, typical Class_C home network. ------------------------------------------------------------------------------------------------------------ Been trying various utilities like "nslookup -debug localhost" on the server to understand what is wrong/changed but I don't want to mess up my configuration too much.. Cheers, Nitish. essencenetworks(a)gmail.com stay safe + well https://covid19.govt.nz
