片刻、瞬間、不知所云...

#pkg_info
MailScanner-4.38.1

update ports tree:
#cvsup -g -L 2 /usr/ports-supfile

then install portupgrade:
#cd /usr/ports/sysutils/portupgrade
#make install
#make clean

backup MailScanner.conf
#cd /usr/local/etc/MailScanner/
#cp MailScanner.conf MailScanner.conf.438

upgrade MailScanner
參考網址：http://www.sng.ecs.soton.ac.uk/mailscanner/FreeBSD.html
#cd /usr/ports/mail/
#/usr/local/sbin/portupgrade MailScanner //大小寫要和pkg_info相同
..............


有部份注意事項，請參閱前述網頁說明。
我使用portupgrade MailScanner做到最後會失敗，只好用
#pkg_deinstall mailscanner-mrtg
#pkg_deinstall MailScanner
#cd /usr/ports/mail/mailscanner
#pkg_reinstall MailScanner
↑用這個方法在ns2時ok, 但用在ns1時失敗，原因在/usr/local/share/MailScanner/reports/tw/languages.conf更新會失敗。
所以我先把這個目錄移到其他地方，再到
#cd /usr/ports/mail/mailscanner
#make install
就更新完成。

更新clamav比較簡單，直接：
#portupgrade clamav
就自己裝完了。
