- List patches applied
patchadd -p
- To apply a patch
- Untar the patch tar.Z
patchadd <dir>
- To add a package
pkgadd -d <package file>
- To add a package in tar format
tar xvfz package.tar.Z pkgadd -d .
- This will ask you which packages in the current directory you wish to install.
- To remove a package
pkgrm <package>
- To get info on a package
pkginfo -x <package> pkginfo -l <package>
- To list all installed packages

- To find out what files are in a package
grep <package> /var/sadm/install/contents
Patch Management
The most common commands
install_cluster - install cluster patches by using the command. This is command used for installing Recommended Cluster, the most common patching method in Solaris. You can also manage patches through the Solaris™ Management Console, but command line is simpler.
showrev -p -- List patches
patchadd – Installs uncompressed patches
patchrm – Removes patches installed
Important directories
/var/sadm/pkg directory is used to save the base packages
/var/sadm/patch contains the list of installed patched. The date of the creation of a directory for a particular patch is actually the date of patch installation.

Sendmail
Configuring the Solaris-supplied version of Sendmail In this example, I will configure the version of Sendmail (8.11.7) that was installed by default on a Solaris 8 system. Sendmail will be configured to use header sender and envelope sender address masquerading and a "smart host."
On Solaris 9, substitute main.mc for main-v7sun.mc in the instructions.
1. Change to the directory containing the Sendmail configuration files.
cd /usr/lib/mail/cf
2. Make a copy of main-v7sun.mc as sendmail.mc, and make modifications to sendmail.mc.
cp main-v7sun.mc sendmail.mc
3. Configure sendmail.mc. In this example, we want to use the "smart host" smart_host.example.com and masquerade both the header sender and envelope sender addresses as example.com.
vi sendmail.mc
Insert the following entries before the MAILER lines:
define(`SMART_HOST', `smart_host.example.com') MASQUERADE_AS(`example.com') FEATURE(`masquerade_envelope')
4. Build the sendmail.cf file from the sendmail.mc file.
/usr/ccs/bin/m4 ../m4/cf.m4 sendmail.mc > sendmail.cf
5. Test the sendmail.cf file.
/usr/lib/sendmail -bt -C./sendmail.cf
Make sure that root is an "exposed user." An exposed user is a user that will not be masqueraded. This is used when accounts, such as root, are not unique across systems.
> $=E root
Test header sender and envelope sender masquerading:
> /tryflags HS > /try esmtp user@host.example.com Rcode = 0, addr = user@example.com > /tryflags ES > /try esmtp user@host.example.com Rcode = 0, addr = user@example.com
6. Backup the existing sendmail.cf file.
cp /etc/mail/sendmail.cf /etc/mail/sendmail.cf.date
7. Install the new sendmail.cf file.
cp sendmail.cf /etc/mail/sendmail.cf
8. Sendmail the Sendmail process a SIGHUP to begin using the new configuration file.
kill -HUP `head -1 /var/run/sendmail.pid`
