> pfexec lpset -a banner=never lp01
> pfexec lpadmin -d lp01
> pfexec enable lp01
> pfexec accept lp01

Regenerating an SSH Host Key

26-Feb-10

Use ssh-keygen, just like you would with an account’s key pair:

# ssh-keygen -f /etc/ssh/ssh_host_rsa_key -N '' -t rsa
# ssh-keygen -f /etc/ssh/ssh_host_dsa_key -N '' -t dsa

pfexec as sudo replacement

26-Feb-10

To use pfexec similarly to sudo, use “usermod” to give the account the “Primary Administrator” profile:

# usermod -P'Primary Administrator' aleonard

“aleonard” will now be able to preface commands with “pfexec” to run them as root, similar to sudo when configured not to prompt for a password.

Using Sendmail Maps on Solaris

26-Feb-10

Configure ‘/usr/lib/mail/cf/sendmail.mc’ to meet your needs; for example, to use the access_db and mailertable features:

divert(0)dnl
VERSIONID(`@(#)sendmail.mc 1.11 (Sun) 06/21/04')
OSTYPE(`solaris8')dnl
DOMAIN(`generic')dnl
FEATURE(access_db, `hash -o -T /etc/mail/access')
FEATURE(mailertable, `hash -o /etc/mail/mailertable')
MAILER(`local')dnl
MAILER(`smtp')dnl

The new ’sendmail.cf’ can be built in ‘/usr/lib/mail/cf/sendmail.mc’ by running ‘make’ as root. Copy the new ’sendmail.cf’ file to ‘/etc/mail’ and restart sendmail by running:

# svcadm restart sendmail

An example mailertable mail map would be as follows:

example.org smtp:mx.example.org

Once your map files are ready, use ‘makemap’ to create the database files for each map:

# makemap -v hash mailertable < mailertable
# makemap -v hash access < access

Scan for Hot-Added Devices in Solaris 10

22-Feb-10

Use “devfsadm”; from the man page:

devfsadm(1M) maintains the /dev namespace. It replaces the previous suite of devfs administration tools including drvconfig(1M), disks(1M), tapes(1M), ports(1M), audlinks(1M), and devlinks(1M).

.ssh/config settings for EC2 hosts

21-Feb-10

Seen multiple places around the web; I’m not sure where attribution should lie, but this is not original to me:


# ~/.ssh/config
#
Host *.amazonaws.com
CheckHostIP no
StrictHostKeyChecking no
UserKnownHostsFile /dev/null
