FreeBSD mempunyai tools untuk update & upgrade namanya freebsd-update. Tidak seperti distribusi linux dimana kernel dan base systemnya didevelop terpisah, FreeBSD mempunyai base system yang solid dimana “base system” dan kernel freebsd adalah satu kesatuan. jadi core developer FreeBSD selain mendevelop kernel, mereka juga sekaligus mendevelop base-system mereka.

Jika mengambil contoh disto ubuntu, kernel linux didevelop oleh linux foundation yang berada diluar canonical, yang dipimpin langsung oleh linus torvalds. Kemudian oleh canonical, kernel linux dibundel dengan software-software lain dan menjadi base-system.

Base system adalah kumpulan program standar yang menjadi basis sistem operasi. inti dari Operating System kan kernel toh?. tapi apa cukup kalo cuman kernel doang? trus kita ngetik command dimana? untuk itulah diperlukan base-system. contoh program yang termasuk dalam base-system ini: shell (csh, sh), basic utilities (cp, mv, ls, mkdir, cd, rm, rmdir, dll), device management, dll.

Istilah update artinya memperbaharui software yang telah terinstall tapi hanya perubahannya hanya minor saja. hal ini terlihat dari perubahan nomor versi yang kecil misal: dari 9.0-RELEASE-p1 ke 9.0-RELEASE-p2. nomor mayornya tetap sama, yaitu 9.0.

The Webmin server is an open source tool that enables system administrators to manage systems that run the Solaris Operating System, UNIX, or Linux using a web browser. You can access the server using HTTP or HTTPS. Webmin is included in the Solaris 10 OS; however, the version included is an old version with a default certificate.

If you update Webmin to the latest version, the HTTPS support doesn’t work unless you use the following steps.

1. Set up the Webmin server that is included with the Solaris 10 OS by executing the following command as root:

/usr/sfw/bin/webminsetup

2. You can press ENTER to answer the two first questions, but for the third question, answer y:

Login name (default root):

Web server port (default 10000):

Use SSL?  [y,n,?,q] y

3. Access the Webmin server using a web browser by typing the address https://SERVER.IP.ADDRESS:10000.

4. Log in using the root user name and root password.

5. Create your own certificate:

• Go the Webmin Configuration Option and then go to the SSL Encryption module.
• In the Create Certificate option, fill in the form. In the Server Name field, put the server’s IP address.
• Click Create Now.

6. Before updating Webmin to the latest version, copy the Perl files that support HTTPS and SSL encryption to the Perl library directory:

cd /usr/sfw/lib/webmin
cp -r perlmod/* /usr/perl5/5.8.4/lib/

7. Configure the proxy settings, if necessary. If you access the Internet through a proxy, set your proxy information in the Proxy Servers module of the Webmin Configuration menu.

8. Update Webmin to the latest version:

• In the Webmin Configuration menu, select the Upgrade Webmin module.
• Select the option Latest version from http://www.webmin.com, and then click Update Webmin. You can also update the Webmin modules in the Update Modules option of this module.

Now you can manage your systems running the Solaris 10 OS with the latest version of Webmin in a secure fashion using HTTPS.

Configure webmin SMF after upgrade

to start webmin

# svcadm enable  svc:/application/management/webmin

to stop webmin

# svcadm disable  svc:/application/management/webmin

check webmin daemon log:

# tail -f /var/svc/log/application-management-webmin\:default.log

edit webmin configuration script:

# vi /var/svc/manifest/application/management/webmin.xml
<exec_method
 type='method'
 name='start'
 exec='/etc/webmin/start'
 timeout_seconds='30' >
 </exec_method>
