One thing I should mention is before I added the software to do USER Remote access to chroot a user to a certain file I didn't have this problem...
I could get in from an outside network VIA FTP.
I also installed a whole bunch of updates like an idiot because I was hoping the USER Remote access software was in the updates.
"Act in haste, repent at leisure"
So is there a command I could use to restore all previous settings without uninstalling the USER Remote access and the Lets encrypt Security Certificate?
Restore from backup and start again? Letsencrypt can be easily be re-generated.
OK, so you have been jumping wildly all over the place trying to guess your way to an answer rather than working it out methodically and finding what works and what does not.
This is fast becoming a XY problem which no one is going to be able to resolve very easily and is consuming everyones time and getting nowhere in a hurry:
https://xyproblem.info/So, first thing
go right back to the start and then work your way forwards little step by little step and documenting the process accurately. No jumping around or testing things on a whim. Be precise and methodical. Use logs. Read the wiki carefully - there is a wealth of information in there so use it to educate yourself.
This was an upgrade from SME v8? I don't believe we tested this, but it should *theoretically* work but YMMV.
So run the audittools on your SME v8 install and lets see what you have in there to start with.
Run these from a terminal.
/sbin/e-smith/audittools/newrpms << May not run correctly on SME v8
/sbin/e-smith/audittools/repositories
/sbin/e-smith/audittools/templates
Then do the same thing on the v10 version - you can actually go to the server-manager and look down the bottom on the left for creating a bug report - that will do it all for you.
Put them on pastebin or somewhere - not here.
I suggest you also give some give some details about your router or whatever you have between your server and the rest of the world, and how it is set up.
Make sure you *** anything sensitive please.
Further fumbling and guessing is not going to get this fixed. This needs a professional approach now please.
