                  Yes, those are debugging statements and looks fine.

                        Don't know if this is the same issue, but i noticed this yesterday.
                        Running 1.0.1-SNAPSHOT-03-18-2007 built on Thu Mar 8 22:14:44 EST 2007.

                        For some unknown reason, my pfSense box lost it's WAN dhcp ipaddress, but my
                        WatchGuard box connected to the same ISP outlet(i use a switch to get several ports)
                        did not have any problems recorded, and it to runs on a WAN dhcp. The WatchGuard box
                        uses something called udhcpc. I don't know if it's better, worse or the same as dhclient.

                        Pressing the Renew button in Status–>Interfaces had no problem of getting a ipaddress.
                        I pressed the button around 20:15.

                        Got this from the syslog(if was not at home when this happened):

                          Remove snort and see if the problem persists.

                            removing snort won´t change a thing, he got the same error i do,and i don´t use snort. And as i said it only happens one time after reboot, pressing the renew button clears the problem.

                            the dhclient error is not fixed !

                              I removed Snort a couple of hours ago, and will give it a go
                              try to reproduce the issue by rebooting the pfSense computer
                              and not reinstalling Snort for a while.

                                Calm down there pal.  Snort gets RELOADED at the same time that dhclient invokes… So you don't know what your talking about quite frankly.

                                  Alright, it happened again a couple of minutes ago.
                                  Pressing the Renew button gave me back my ipaddress within 5 seconds.
                                  Checked traffic on my WatchGuard box and it did not record any problem with the internet.

                                  I pressed the Renew button around 08:27.

                                  This is what i have from syslog:

                                    We REALLY wish that we could reproduce this…  Everything we have tried does not reproduce it :(

                                      Is there a way of asking dhclient to produce more info for debugging purposes?
                                      I would glady run it in a mode like that :).

                                      I don't really know what short write is, but from the looks of it, is it possible
                                      to alter dhclient so that it does not invoke a shutdown of it self when the
                                      short write event occurs?

                                      ??? What is short write?
                                      ??? What is the criteria for triggering that kind of response from the dhclient?

                                      Selective, it would be interesting to know what country you are from and what
                                      ISP you are using plus what type of physical connection the ISP delivers to you.

                                      My ISP is TeliaSonera in Sweden and they deliver my internetaccess to a standard
                                      RJ45 LAN Cat5(e?) port.

                                        im using telia as well, but through ADSL.

                                        The strange thing is that it only happens once, after reboot, so it must be something wrong with boot process..

                                          I doubt it has anything to do with the boot sequence.

                                          Short writes in this case is the privilege separation code.  This appears to be a deep FreeBSD bug of some sort.
