    UNIX kernel screwed up

    hey guys,
    I rebuilt my kernel after some patching on my FreeBSD 4.7 box and am now getting really wierd stuff like
    Jan 8 10:34:05 UNIXbox sshd[2076]: getting vmemoryuse resource limit: Invalid argument

    this netstat display is wierd too. I've got port 22 (SSH) open but look at this:

    Active Internet connections (including servers)
    Proto Recv-Q Send-Q Local Address Foreign Address (state)
    udp4 0 0 *.1052 *.*
    udp4 0 0 *.518 *.*
    udp4 0 0 *.514 *.*
    udp6 0 0 *.514 *.*
    Active UNIX domain sockets

    Did you just patch or you updated to -stable with cvs, in which case you might want to try rebuilding userland also...

    Here's what I do:

    cvsup mysupfile
    cd /usr/src
    make buildkernel KERNCONF=MYKERNEL
    make buildworld
    make installkernel KERNCONF=MYKERNEL
    make installworld
    mergemaster

    With cvs you can track:

    RELENG_4 (Which will turn 4.7-stable, 4.8-prerelease, 4.8-stable etc.)
    RELENG_4_7 (which will track 4.7-stable including sec. fixes)
    RELENG_4_6 (which will track 4.6-stable incl. sec. fixes)

    For more tags see the FreeBSD handbook CVS Tags section.

    Anyway. Always do the whole thing (except when you're just recompiling your kernel because you tweaked it, after a comlete build).

    A good thing(tm) to do if you run into trouble is to compile the GENERIC kernel and give that a try.

    Everything that's not build into the kernel will be dynamically loaded anyway.

    hi,
    I rebuilt my kernel after some patching on my FreeBSD 4.7 box
    You need to reboot to single user mode to test your new kernel you just built..when reboot the system at the boot prompt enter -s flag.
    At the shell prompt you should then run:
    #fsck -p
    #mount -u /
    #mount -a -t ufs
    #swapon -a

    This command will checks the filesystems,remounts / read/write, mounts all the other UFS file systems referenced in etc/fstab and then turns swapping on.
