sysinstall
cd /sys/i386/conf ; make LINT
Rescue
Snapshots
Kernel modules
kldload kldstat etc
Hardware info
kenv pciconf -lv grep -i cpu /var/run/dmesg.boot sysctl hw.ncpu
Checking resources
systat -pigs fstat -f /var systat -vm iostat
Building a kernel
cd /usr/src/sys
FAQ
Upgrading
cd /usr/src make buildworld make buildkernel KERNCONF=mykernel make installkernel KERNCONF=mykernel
or
portupgrade -P -f -a
Courier-imap certificates
check out /usr/local/share/mkimapdcert
crontab: temp file must be edited in place
Happens when you set EDITOR=vim. Fix it by setting :set nobackup and :set nowritebackup in .vimrc
ping: sendto: Permission denied
sysctl:
security.jail.allow_raw_sockets: 0
Timezones
- adjkerntz
- tzsetup
- ntp
Ports
Post install messages
/usr/ports/*/*/pkg-message
exclude from csup
To exclude for example /usr/ports/japanese, put in /var/db/refuse
ports/japanese
(or a refuse file in whatever base you defined in supfile)
config options used for a port
/var/db/ports/*/options
ssh taking a long time
In /etc/ssh/sshd_config
UseDNS no
files installed by ports
/var/db/pkg
Using large ( >2T ) drives
gpt create mfid1
create a 'slice' of 200000 sectors (this will automagically create /dev/mfid1p1
gpt add -s 2000000 mfid1
create one taking up the rest (/dev/mfid1p2)
gpt add mfid1
Migrate users/accounts
http://www.ggis.biz/wiki/index.php/FreeBSD_-_Migrate_Users
After editing /etc/master.passwd run
pwd_mkdb /etc/master.passwd
(careful with this not entirely tested advice )
truss: cannot open /proc/curproc/mem: No such file or directory
kldload procfs mount_procfs /dev/procfs /proc
But you're supposed to use sysctl?
Networking
Set default route
route add default 10.0.0.1
Delete default route
route delete default
rm: Operation not permitted
ls -lo chflags noschg
