General tips about protection against locking yourself out - Raspberry Pi Forums


having locked myself out fiddling around config (i suspect) , stuffing ssh, want ask if there general tips protecting getting locked out config changes, user account / password changes or bad updates?

ideas (very vague, ignorant, ill-defined):

* backdoors (well-secured ones), auxiliary protocols remote admin;

* second user account

*'revert config' batch jobs run in timer, config , auto-revert on timeout. (my router has this, auto protection against not being able log in following bad config change). of course, such things had written, , correctly, no bugs, , have remember set timer. perhaps try , automate such general , re-usable.

*backups - don't know how general complete backup, , in case not restore if locked out.

i'd go backup route
take sd card out, insert in computer
copy config file said computer
put sd card in pi , mess content.
