comet424 Posted July 17, 2021 Share Posted July 17, 2021 in the past i used to have the go file do the mkdir and chmod and the cat >>authorized keys or what not then the latest version of unraid told me not to do that anymore in fix common fixes.. and i remmed out all that code and for the longest time it still worked between reboots but now i noticed with user scripts the rsync between servers is broken.. when i shell it i have to do the authorization i thought i should no longer have problems as long as the keys are in the flash's .ssh folder but it doesnt work? so what should i do ti get it up and running again with no issues cuz i didnt understand the documentation back then i guess as long as its in the .ssh folder it should just copy over and import on its own but now it doesnt work and i wish there was a notification to say rysnc userscripts the connection between the servers are broken Quote Link to comment
JorgeB Posted July 18, 2021 Share Posted July 18, 2021 Try again after rebooting in safe mode, a bad behaving plugin can cause that. Quote Link to comment
comet424 Posted July 18, 2021 Author Share Posted July 18, 2021 oh ok i know the Unraid My Servers plugin has caused me issues i forgot to uninstall it as it has made it before you cant boot up unraid... and the pluggin has disabled the Tower login.. when you boot into safe mode then what do you do? ill have to replug in a video card.. its headless unless i can boot into safe mode from console? and would removing the unraid plugin fix it pics are from last week but i ment to uninstall the plugin ill probably uninstall it later today i not at home at the moment.. possibly this is the reason?

comet424 Posted July 18, 2021 Author Share Posted July 18, 2021 (edited) i just uninstalled the my servers plugin.. and just rebooted unraid i need to plug a video card in to be able to change to safe mode but rebooted unraid it didnt work so once in safe mode? what then how do i fix it? so does that mean any plugin that breaks can break the ssh stuff? hopefully next release of unraid can fix it so plugins cant break it.. is there a certain that plugin that causes the ssh to fail and not work.. that i can check Edited July 18, 2021 by comet424 Quote Link to comment

Plugins can break anything as they have unrestricted access to the system which is the reason that Safe Mode was introduced in the first place to allow users to easily suppress the loading of plugins. It is also one of the reasons that it is recommended that Docker containers (or VMs) be used where possible as this provides a level of isolation from the core Unraid system. Quote Link to comment
comet424 Posted July 19, 2021 Author Share Posted July 19, 2021 @JorgeB@itimpi so then dockers and vms are safer then plugins.. so does that mean the Unraid limetech my servers plugin is considered bad as its not a Docker or a VM? so i booted into safe mode.. i did the gui no plugins.. it gives me a login. i used my windows machine and ran the terminal... went into root/.ssh folder and no other things there other then what you see.. i tried to ssh root@backupserver but asked for that finger print thing and said host failed.. i reboot tower.. and i still have no login for the main server.. but able to access the gui still.. so here some pics and a diagnostic.. maybe it can tell you. but wouldnt your system logs tell you which exact plugin broke unraid.. or broke the SSH built in feature.. i havent had a chance to uninstall some of the plugins as i was gonna see if any over lapped any etc the last 2 photos are from other day.. just before i uninstalled the unraids my server plugin you can see there also i do not have a login anymore and if some plugins are bad why they on the community apps.. but can you see what plugins i should remove then? hope it helps tower-diagnostics-20210719-1337.zip Quote Link to comment

No, and it's not clear to me after reading your post if pass-wordless SSH started working in safe mode, did it? Quote Link to comment
comet424 Posted July 19, 2021 Author Share Posted July 19, 2021 no i.. i went to shell i typed ssh root@backupserver it asked for your fingerprint i typed yes it said host failed Quote Link to comment
JorgeB Posted July 19, 2021 Share Posted July 19, 2021 Then it's not a plugin problem, you can create new keys and make sure all is correctly configured, IIRC we already went through this with you in another thread. Quote Link to comment

There is functionality that can only be implemented as plugins because of the level of access to the system that is required, and it may well be the my servers plugin falls into that category.

comet424 Posted July 19, 2021 Author Share Posted July 19, 2021 (edited) @JorgeB i dont know what you talking about "!!RC" i know i asked about ssh keys before to get the out of the Common Fix Issues plugin you rem out it all.. and you have all the keys in the .ssh folder and boom bobs your uncle your done.. from what i understood from that other thread. as the Documentation isnt detailed enough for joe blow to understand it.. its written in crypted.. as it should say place your keys in "/Flash/config/.ssh" and thats all you need Unraid will do the rest plain and simple and then show steps how to create the key.. and that you no longer need chmod cat any of that in the go file anymore but like i said thats how i read what you guys told me in the other form delete the go file for the chmod cat scan thing.. and unraid will do the rest.. and that worked for a while.. i dont think recreating keys will fix the problem of unraid not copying the keys from the .ssh folder into the /root/.ssh/ known hosts file thoguh? but that no longer works.. and so if i recreate the keys it doesnt solve the problem... does solve it why its not copying from the USB drive.. and Why you can no longer use the Login on the Server anymore its disabled like you seen.. @itimpi ah ok well learning stuff new everyday so i rebooted back into unradi safe mode i get errors booting up and it hangs alot but you can see i had to recreate a key as u see unraid isnt mkaing that known_hosts file also last couple pics are when i reboot the unraid it hangs and like i mentioned above .. there is no longer a login plus why is there an error for Plugins when it safe mode? its not supposed to be running plugins? but what i dont understand is.. you guys have the diagnostic file.. why doesn it show step by step whats loading and what craps out.. so you can see yup this file caused the corruption or caused the issue? like file wont load or something.. or reinstall this.. like windows does or like when you get the blue screen of death.. microsoft knows what caused the crash by minidump.. doesnt unraid have something like that? also can you address why the login is gone. and is there a way to notify you when .ssh failed to copy. and user scripts failed to rsync Edited July 19, 2021 by comet424 Quote Link to comment
comet424 Posted July 20, 2021 Author Share Posted July 20, 2021 (edited) so far 0 luck i deleted the /flash/config/ssh/root folder as i noticed there is a folder in there that used to never be there so unraid would be forced to load all those keys in the ssh folder.. but it didnt work when i rebooted.. now the /root/.ssh/ folder is empty so i wasnt able to get it to force it in and i was unable to get the login screen back.. what plugin breaks the login? update: on the ssh part not they login so i figureed it out which no one told me in my other post.. as no one is step by step detailed you still gotta use the mkdir you still gotta use chmod keyscan and cat.. but you only have to run it once.. then it saves it.. and unraid takes those saves to the flash so when you reboot all it does is copy that folder..... if someone would have said all you gotta do is just re run those commands in my go file to import.. i wouldnt spent hours last night reboots and such.. unraid docs should tell you that too.. when unraid looses keys folder.. all you gotta do is run mkdir,cat,keyscan,chmod, to restore it.. so keep a copy of your script.. dont toss it.. so least i figured it out trial and error and figured id try it thanks for the help i appreciate it all Edited July 20, 2021 by comet424 Quote Link to comment
