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.

SD Datastring Convention

i wondering if there preferred convention appending data logged?  see standard sd example uses: code: [select] void loop() {   // make string assembling data log:   string datastring = "";   // read 3 sensors , append string:   (int analogpin = 0; analogpin < 3; analogpin++) {     int sensor = analogread(analogpin);     datastring += string(sensor);     if (analogpin < 2) {       datastring += ",";     }   } creating string called datastring, , appending it, have seen in forums string not liked.  around this, code data logging looks this: code: [select] void sdupdate() {   datetime = rtc.now();   unsigned int hour = now.hour();   unsigned int minute = now.minute();   unsigned int second = now.second();   char datastring[100] = "";   char char_current_pay[15] = "";   char char_overall_pay[15] = ""; ...
