documentation:anti_virus:mcafee:install [MailScanner Wiki]: "vlnxp4440l.tar.Z"

Installing McAfee VirusScan for Unix
Since McAfee VirusScan is a commercial anti-virus scanner you will have to purchase it.

If you already have bought a site license of some form you may be eligible to download a version suitable to you already, “free of extra charge” (It might be as easy as going to the download page, choosing “Product upgrade”, entering your organizations grant number, choosing →“VirusScan Commandline Scanners”, agreeing to the terms and finally clicking on the file you want;), or if you have a valid license.dat you should be able to download and install the trial version, then just replace the license.dat file with your own.

Download the version for your intended server OS.


Generic tar install (AIX/FreeBSD/HPUX/Linux/Solaris)
Put the package in a directory and unpack it (the linux version will be used in the example):

[root@mail ~]# mkdir viruscan4400
[root@mail ~]# mv vlnxp4440l.tar.Z viruscan4400/
[root@mail ~]# cd viruscan4400/
[root@mail viruscan4400]# tar xvzf vlnxp4440l.tar.Z
or
[root@mail viruscan4400]# gzip -cd < vlnxp4440l.tar.Z | tar xvf -


Then run the install-uvscan script (as root) to install into the default directory /usr/local/uvscan:

[root@mail viruscan4400]# ./install-uvscan
Which directory do you want to install into? [/usr/local/uvscan]
Uninstalling previous version … done.
Do you want to create the link(s) to uvscan in /usr/local/bin [y]/n
Do you want to create the link(s) to uvscan_secure in /usr/local/bin [y]/n
Do you want to create the link(s) to liblnxfv.so.4 in /usr/local/lib [y]/n
Do you want to create the link(s) to uvscan.1 in /usr/local/man/man1 [y]/n

Installation complete.

Do you want to perform a scan of all filesystems y/[n]

And that’s all you need do. Now, to use it in MailScanner, first run update_virus_scanners to download the latest DAT files immediately:

[root@mail viruscan4400]# update_virus_scanners

and then edit MailScanner.conf to include mcafee in your “Virus Scanners” setting.


Notes and historical issues
Specific information regarding prerequisites are in the readme.txt (in all packages).
There are two versions for x86 Linux, where the vlnx4… version is for older kernels/distributions (2.2/2.4), and the vlnxp4… version is for more recent offerings (2.4/2.6 kernel, libc6, optimized for P4s (but works on regular pentiums)). This difference is not that well documented at the download page.
There are also versions for SCO Open Server and Linux on IBM S390. These lag a bit version-wise, and will be End Of Life with version 4320. Check the End Of Life list for current information.
Engine version 4320 is susceptible to this vunerability (ISS), McAfees PDF, McAfees FAQ. Solution is to update to 4400 immediately, and implies that 4320 is deprecated.
There has been issues using uvscan on systems where part of the scanned paths involved have been symbolic links. The standard recommendation (whether it still holds or not) is to not use symbolic links in conjunction with the mcafee scanner.
Some (older) versions have been known to need compatibility libc files installed (mainly linux versions), and has further been known to spew error messages about the inability to access the CD drive onto the textmode console.

每個角落都有人生

最近無意中開始追看日本電視劇「この世界の片隅に」(中文翻譯 「在這個世界的某個角落裡」)。 故事從現代開始,一個妙齡女子因為工作不如意,依然遠走到一個從未踏足過的地方—廣島的某個即使日本人都不能正確發音的地方「呉」市。 但是她是有目標的,直接去到一個在山腰上的民居,但是已經荒廢....
