Is there a way to backrev to 2.2.5? 2.2.6 is no good for me… cp dies often

  • C

    We've been on 2.2.6 for a few weeks now, and now that students are back, the captive portal has been dying a good amount (several times a day).  I haven't been able to find a problem in the logs.  I am looking more now.  Being that I though it couldn't be any worse, I snapshotted then upgraded to 2.3, but it looks as through the captive portal code has changed enough where it generated a php error submitting a username/password for radius.  That was grasping at straws.  But at this point, I want to roll back.

    Can someone point me to the 2.2.5 images?  I may just do a total backup, then build a 2.2.5 image and do a restore (hoping it works)

  • 2.2.5 is still on the mirrors. Just go to the download page, select the 2.2.6 image, and click the link 'just show me the mirrors'

    Then reinstall the 2.2.5 backup config you took before you upgraded.

    Yes, I have the same issue, CP service dies often in my 2.2.6 box too, but I have only two boxes, not sure if this is a common issue.

    I will downgrade to 2.2.4, and check if the issue still exists.

    What are the symptoms when this happen? New user cannot login? Are existing sessions affected?

    What do you see in the logs - "System" en "Portal Auth" ? (activate "Log errors from the web server process." on the Status: System logs: Settings page)
    How do your user authenticate ?

    Out of curiosity, I was having issues with my captive portal.  I had to kill the proces and restarted and ever since I've had no issues.

    Hi,
    the Captive Portal dies at my installation too.  It never happened with the 2.2.5 version.

    I have 3 pfSense 2.2.6 VM (ESXi) each one with a CP and every day almost one lighttpd process dies without apparent reasons.

    Last kernel log entries:
    CP1:
    Feb 5 17:15:01 kernel: pid 31555 (lighttpd), uid 0: exited on signal 10 (core dumped)

    CP3:
    Feb 6 22:04:52 kernel: pid 91600 (lighttpd), uid 0: exited on signal 6 (core dumped)

    CP5:
    Feb 6 17:25:05 kernel: pid 41922 (lighttpd), uid 0: exited on signal 11 (core dumped)
    Feb 9 08:18:21    kernel: pid 57014 (lighttpd), uid 0: exited on signal 11 (core dumped)

    Only the process related to the SSL CP dies (port 8003) and I'm non using the plain HTTP (no connections to port 8002);  I have to restart the CP service from the GUI.
    The portalauth log lists correctly "USER LOGIN" until the process death, after that I can only see "TIMEOUT" for the users already logged-in and no new logins through my RADIUS server because users are unable to display the login page and POST credentials.

    Hope my informations will be useful; now I have to monitor the lighttpd process to manually restart the CP as soon as possible (that's really a big problem last time it was down for 2 days week-end). If I will not found soon a resolution, I have to downgrade to 2.2.5

  • From what I make of it :
    Freebsd lightpd signal 10 => https://www.freebsd.org/cgi/man.cgi?sektion=3&query=signal => bus error => hardware error.
    Freebsd lightpd signal 6 => http://lists.freebsd.org/pipermail/freebsd-questions/2004-April/042665.html => lighty is killing itself because "he can't stand the load anymore …".

    Not enough resources ?
    Idea : Get pfsense out of this "ESXi" thing, and "do what we all do" and check again ...
    Another idea : 'tcpdump' the NIC of your portal .... someone is over loading it ?

    Ok, so I am glad other people are experiencing this.  I forgot about my post.  What is interesting is that when the portal dies, there is nothing in the log.  It just stops logging.  But everything else is functioning.  I actually decided to go entirely crazy, and in a production environment, I upgraded to the 2.3 experimental track when the 2.2.6 was having to be rebooted MULTIPLE times in a day.  it was easier for me to snapshot (on VM), the server, then upgrade and see.  I had to add a 'zone' value in the login page, however.

    I upgraded to whatever the daily build was last Thursday, and the server has been running without issue since then.  I am going to declare victory if I make it through tomorrow.

    I can only hope whatever bug is in 2.2.6 does not make it to the 2.3 track.

    To answer some of the questions…

    I run 4 pfsense boxes on VMware.  I have given them 4 cores and 8 gigs of memory (plenty).  When the service dies, if I person connects to our onboarding SSID, the DNS responder correctly gives the person the pfsense IP address for whatever DNS entry they are looking up, then the connection just spins.  No page is launched.  I can't tell you for sure what happens to pre-existing connections.  We have 10 minute time outs, and by the time I discover the problem, the 10 minutes is up and captive portal status reports 0 users.  I am not going to run this on physical hardware, because in our environment, it can be just too problematic.  Since I run about 200 VMs just for my group, and nothing else has issues, I am going to say this is a pfSense issue, not a platform issue (I have about 60 servers on FreeBSD).  This is not a rinky dink environment, and it is on a platform that cost millions.  In the past versions, lightd would die periodically (maybe once a month), and it would be logged to splunk and I would get an alert and reboot the box.  It didn't happen enough to really bother me (this is free, so what can you do?).  But with 2.2.6, it was dying in a way that I got no messages in my log, and I would eventually get calls from the helpdesk.  It was so bad, I was considering pulling out the entire service and doing something else.

    users authenticate via an https portal which connects to a radius backend (off server) to authenticate.

    This was the old trusty message I would look for to see if the captive portal died.  The new 'dying' method doesn't do this:

    network    lighttpd                1                        syslog        IP_REMOVED                    Sun Jan 24 10:17:57 2016    splunkindex0p    /var/log/SPOOL/networking-current/daemon-networking.log    Jan 24 10:17:57 152.2.78.166 lighttpd[31698]: (mod_fastcgi.c.2912) connection was dropped after accept() (perhaps the fastcgi process died), write-offset: 8192 socket: unix:/tmp/php-fastcgi-cpzone.socket-5

    Hi,
    I was going to install the 2.2.5 version when I found this issue:
    https://redmine.lighttpd.net/issues/2700
    resolved with verion 1.4.39  https://www.lighttpd.net/2016/1/2/1.4.39/

    The lighthttpd verion on pfSense 2.2.5 is 1.4.37 but on 2.2.6 I have lighttpd/1.4.38

    Now I'm going to
    pkg install lighttpd
    trying with lighttpd/1.4.39

    @carzin what is the lighttpd on your pfSense 2.3 ?

    I Hope this will help.

    Easter:  Thank you very much for figuring that out.    On the 3 remaining the version 1.4.38 is installed.

    I am glad this package is gone with 2.3.  It has been the source of much grief for me.

    Hi carzin,
    after more than 20 hours since  lighttpd-1.4.39_1 installed, there are no crashes and now the CP is handling more than 1500 users logged-in concurrently.
    On Monday I can provide more data, anyway now I think the issue could be resolved this way.

    The sequence I used are:

    pkg upgrade

    (just to install/upgrade pkg binaries)

    pkg install lighttpd

    on pfsense console menu choose: 11) Restart webConfigurator 
    (to restart lighttpd processes without to force log-out users)

    @carzin:

    Thank you very much!  I've done this on all my boxes.  Time will tell.  I'll just keep hoping that my box running 2.3 continues to do so without issue :)

    Hi carzin,
    my setup is working well uninterrupted since the lighttpd "upgrade"

    I hope will be released an official update for pfSense CaptivePortal.

    How to report this bug to packager?

    It's an issue in lighttpd itself, which we won't do anything about since lighttpd's removed from the next release entirely (because they kept putting out buggy releases, like this as one example of multiple ones in the past several months). So no need to report it, it's already fixed going forward.

    Thanks, cmb.  We have always had some issues with captive portal stability, seemingly linked to the lighttpd process.  I usually get a call from the helpdesk once every month or two when the portal stops working and I restart the server.  It went crazy with the latest release, to the point that I was thinking of abandoning pfsense.  The beta 2.3 build has been super smooth in the nearly 2 weeks it has been up.  When do you anticipate a proper release?

    Its beta_x now. no clue if there is going to be a beta_y or z. then there will be atleast one or more release candidates.
    i doubt they have set a fixed release date at this point. i'm hoping/guessing it'll be between april & june somewhere.

    Hi,

    Same issues for me (lighttpd core dump).
    Sometimes several times per day or a few times per week.
    Already authenticated users are OK but no captive portal page for newcomers.
    I am also trying the lighttpd upgrade to 1.4.39_1… Time will says if it does the job.

    What will be lighttpd replacement in PfSense 2.3 ?

    Same problem here.

    Happens a few times a week, seems random.
    Services status still reports captiveportal as Up so the only chance to know if its down is if a client user is reporting or if you use external monitoring on the CP's http/https.

    Try upgrading lighttpd as others have done successfully, 'pkg install lighttpd', then option 16 followed by option 11 at the console.

    You can check this using CLI (ssh public key auth for automation):
    ps -aux | grep http
    root  13324  7.0  1.4 169520 115368  -  S    2:52PM    57:12.67 /usr/local/sbin/lighttpd -f /var/etc/lighty-ssid_ups-CaptivePortal-SSL.co
    root  11329  0.0  0.1  56884  7736  -  S    2:52PM    0:40.39 /usr/local/sbin/lighttpd -f /var/etc/lighty-webConfigurator.conf
    root  13040  0.0  0.2  67120  17404  -  S    2:52PM    3:42.73 /usr/local/sbin/lighttpd -f /var/etc/lighty-ssid_ups-CaptivePortal.conf

    Or checking log file for Lighttpd 'Core dump' error.

    Does  anyone know if this problem i solved in 2.3 ?

  • Well ….. knowing that "lighttpd" isn't part of pfSEnse 2.2.3 anymore .......  ;)

    2.2.3 works fine for me ....

    Oops : I meant 2.3.

  • S

    Gertjan: The new version is named 2.3
    The version you are referring to, is prior to 2.2.5 and 2.2.6 and still contains lightppd.

  • C

    Yes it is solved in 2.3. lighttpd no longer exists, that's been switched to nginx which has no such problems.
