      In recent (Nov. 13, Dec 14) nanoBSD builds installed on ALIX I'm getting these logs (below) and my 3G connection gets interrupted randomly and the modem is thrown into an un-usable state.

      It's a Sierra C885. Normally it shows a solid blue LED and a solid orange LED when connected properly, but it gets into a state where the orange LED is off and the normally blue LED is blinking orange. It's clearly confused, and I only suspect the getty logs are related.

      What is causing these log entries and how can I get it to stop?

        If you replace /etc/gettytab that should fix that log, pretty sure that's the file, somehow it gets hosed on rare occasions and triggers what you're seeing there. Whether that's related to the 3G modem I'm not sure.

          Well, the /etc/gettytab file is empty. I guess that's why the log is complaining about . . .

          getty: unknown gettytab entry 'Pc'
          getty: unknown gettytab entry 'default'

          because there's nothing in the gettytab file. I guess that's why you said replace it.

          And this?
          tcsetattr /dev/console: Operation not supported

          is something in pfsense trying to perform this unsupported operation?

          Thanks,
          G

            Here's what I put in /etc/gettytab to get getty to start successfully again and stop sending those log messages.

            default:
                    :cb:ce:ck:lc:fd#1000:im=\r\n%s/%m (%h) (%t)\r\n\r\n:sp#1200:
                    :if=/etc/issue:

            P|Pc|Pc console:
                    :ht:np:sp#9600:

            from here:

              In /etc/rc GeekGod added (awhile back) a check for this:

              
# Ensure gettytab is of a sane size
if [ `/bin/ls -la /etc/gettytab | /usr/bin/awk '{ print $5'}` -lt 512 ]; then
    echo ">>> Restoring /etc/gettytab due to unusal size"
    echo ">>> Restoring /etc/gettytab due to unusal size" | /usr/bin/logger
    /bin/cp /etc/gettytab.bak /etc/gettytab
fi

              Is your backup one also broken?

                there is no "/etc/gettytab.bak" file in either of my two nanoBSD 2G installs.

                  Does your /etc/rc reference it at all?

                    Looks like the gettytab.bak file is only made on the livecd and update files. On NanoBSD you could just mount the alt slice and copy it back:

                    If you're on pfsense0 now (check via the mount command):

                    /etc/rc.conf_mount_rw
mount /dev/ufs/pfsense1 /mnt
cp /mnt/etc/gettytab /etc/gettytab
umount /mnt
/etc/rc.conf_mount_ro

                    If you're on pfsense1, just use pfsense0 on the mount command above.

                      @wagonza Yes, this is in /etc/rc

                      if [ "$PLATFORM" = "nanobsd" ]; then
                      …skipping...

                      Ensure gettytab is of a sane size

                      if [ /bin/ls -la /etc/gettytab | /usr/bin/awk '{ print $5'} -lt 512 ]; then
                              echo ">>> Restoring /etc/gettytab due to unusal size"
                              echo ">>> Restoring /etc/gettytab due to unusal size" | /usr/bin/logger
                              /bin/cp /etc/gettytab.bak /etc/gettytab
                      fi

                      @ jimp, thanks, it's fixed already now, and my 3G problems went away mysteriously at the same time :)
                      Lets get that gettytab.bak file on NanoBSD builds. Looks like GeekGod meant for it to be there.
