Error msg: session_start(): Cannot send session cookie



  • In the past few days' snapshots, when instructing pfsense to reboot from CLI (using '5') the following warnings are printed on console:

    Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /etc/rc.initial.reboot:46) in /etc/inc/config.lib.inc on line 502
    Warning: session_start(): Cannot send session cookie - headers already sent (output started at /etc/rc.initial.reboot:46) in /etc/inc/config.lib.inc on line 502



  • My test system is now on:
    2.1-BETA1 (i386)
    built on Mon Jan 7 16:18:04 EST 2013
    FreeBSD 8.3-RELEASE-p5
    During package reinstall at upgrade, it still reports:

    One moment please, reinstalling packages...
     >>> Trying to fetch package info... Done.
    
    Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /etc/rc.bootup:84) in /etc/inc/config.lib.inc on line 502
    
    Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /etc/rc.bootup:84) in /etc/inc/config.lib.inc on line 502
    

    But a reboot at the console is clean (except for all the usual noise of the FreeBSD boot output!). Here is a complete reboot sequence on an Alix 2D13 nanobsd, for the record (sometimes handy to be able to have a current record of what clean boot output looks like):

    Do you want to proceed [y|n]? y

    Ermal added some checks to see if it was running at the command line before doing the session start bit. Perhaps it needs some more logic there, or perhaps you don't have a snap that includes the fixes.

    You can also edit /etc/inc/config.lib.inc and prefix the session start with an @, so it's @session_start( … and then if it fails, it fails silently.
