FreeBSD command reference   Filed Under: Linux & BSD

Introduction

So you will probably think why on earth I’m writing this command reference guide and is normally quite easy stuff. Well the reason is that I don’t spend too much time around servers (most of the time I’m doing networking stuff) so I kind of forget the exact command for how to do things on FreeBSD.

Feel free to post in the comments any other command you may know. I will be updating this post every time I find a command that is useful.

Command Reference

Change the shell for a user

chsh -s "new shell path" user

network card configuration

Edit the file /etc/rc.conf with the following settings:

example interface is named dc0

Static IP address:

ifconfig_dc0="inet 10.2.2.2 netmask 255.255.255.0"
defaultrouter="10.2.2.2"

DHCP configuration:

ifconfig_dc0="DHCP"

To manually setup the default gateway through the command line

route add default IP_Address

Enable GDM on startup

Add to /etc/rc.conf

gdm_enable="YES"

Register a name with DNS when using DHCP

Add to you dhclient.conf file:

send host-name "name";
send fqdn.fqdn "fqdn name";
send fqdn.server-update off;

Apache 2.2

To enable apache 2.2 add to /etc/rc.conf

apache22_enable="YES"
apache_flags=""

If you have the following message “Failed to enable the ‘httpready’ Accept Filter” you will need to load the following module on /boot/loader.conf

accf_http_load="YES"

NTP

To enable NTP on startup add to /etc/rc.conf

ntpdate_enable="YES"
ntpdate_hosts="IP Address"

SNMP

To enable SNMP access on the server, add the following lines to /etc/rc.conf

bsnmpd_enable="YES"
bsnmpd_flags=""

Then edit the file /etc/snmpd.config to modify your Read only and Read/Write strings from the default ones.
