RE: Virus Scanning

I think it depends on how close to 100% you can guarantee that your windows clients are virus free. Depending on permissions on your shares and files, all it could take is one infected windows machine in your entire network to infect thousands of files on your filer. We've had this happen probably at least a half-dozen times. We just have way too many windows machines in our network: desktop machines, laptops that people take home and hook up to their home networks, and often the worst of all lab machines since we often can't fully control how those machines are set up. We have probably hundreds of machines running IIS for web development, trying to keep all of them patched is so far an extremely difficult job. You can block viruses through your mail gateway, but are you blocking employees from accessing hotmail or msn or any other web-based mail? Because viruses can easily sneak into your network from there. Are you blocking/filtering ftp? Because that's another way. Not to mention the various P2P file sharing services. We have Norton corporate edition deployed throughout most of our desktop clients, which in theory should be keeping all the clients up-to-date, but we find far too often that the automated client updates aren't happening, or that the client AV software is not running for some reason, etc. From what I've heard from people using other vendors like Symantec and Mcafee in big enterprise environments, they can be plagued with similar problems as well. We're still working on deploying the Netapp AV solution from Trend (budgeting and planning can sometime take *way* too long) but when we deployed a trial version we were very impressed by the efficiency with which it stopped virus infections onto the file server. We started getting notices of attempted virus infections within minutes of activating the software. For a long time when people complained about viruses on the file server, I would take the position that if we just prevented virus infections on the client side there would be no problem. But I've come to accept that it is just virtually impossible to guarantee that you can keep every client on your network up to date and virus-free at all times. And manually scanning the file server regularly just isn't feasible, given a very large file server it can be like painting the golden gate bridge, and with today's viruses it can only take a window of a few minutes to infect thousands of files. So, in summary, I'd say that virus protection on the file server is very important, unless you are *very* confident that your windows clients will always be virus free, or perhaps if your file server is very very restrictive permission-wise, such that an individual infected user can't do anything more than damage their own personal folders, *and* you have good frequent backups. -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company -----Original Message----- From: Geoff Hardin [mailto:geoff.hardin@dalsemi.com] Sent: Tuesday, March 25, 2003 11:45 AM To: toasters(a)mathworks.com Subject: Virus Scanning I was wondering what other admins were using for virus scanning.

I asked tis list recently regarding the "most popular software" part of your question. Trend seems to have been the winner in that poll, followed by Symantec. The reason I was inquiring is that, despite having file system and mail scanners everywhere else, I found it is still possible to deposit viruses on the filer. With a batch of infected files there, it is only a matter of time until an unprotected client connects and keeps spreading the love. -D. > -----Original Message----- > From: Geoff Hardin [mailto:geoff.hardin@dalsemi.com] > Sent: Tuesday, March 25, 2003 11:45 AM > To: toasters(a)mathworks.com > Subject: Virus Scanning > > > I was wondering what other admins were using for virus scanning. > And as an aside, I really want to know whether it is worth > the time and > money.

Will a DS14 shelf go in to a 900 deep rack?
by Clawson, Simon 25 Mar '03

25 Mar '03

Hi, I have two DS14 selves in an 800mm rack and the went in no trouble. Due to the massive tape library I use I need to switch over to a 900mm rack. Will the rail kit on the DS14 extend far enough back to go into a 900 deep rack?

[SUMMARY]Re: Terminating CIFS sessions via CLI.
by Clarence Ngoh 24 Mar '03

24 Mar '03

Mark The way we have it structured is that the destination file is locked. This is where the users have access to the templates. The source file/location is never locked - this is where the developers update the templates to put to the destination. As one of the people suggested, perhaps the best way to approach this is to rsh to the filer, get the list of username's that have the file opened, then running through a regexp, and then terminating the user's cifs sessions. This job can be scheduled on the weekend or in the wee hours of the morning when we are certain that the file is not needed. -- Clarence.

Terminating CIFS sessions via CLI.
by Ngoh, Clarence 22 Mar '03

22 Mar '03

Hi all I was wondering if any of you has attempted to kill a single or a set of CIFS sessions via CLI? After obtaining the files that are opened via cifs sessions on the filer, I wish to run a regexp through it and kill a set of opened files. Do you if there is a utility for Windows to do this via CLI or if there is an equivalent way of doing this via UNIX? The only method that I am limited to so far is using MMC to list the appropriate open files and terminating it. TIA. -- Clarence. ************** IMPORTANT MESSAGE ************** This e-mail message is intended only for the addressee(s) and contains information which may be confidential.

Moving disk shelfs between filers
by Magnar Stav Johanssen 19 Mar '03

19 Mar '03

Hi! I've got one F630 with 2 disk shelfs, 14 disks and its running OnTAP 5.3.7R3 and one F760 with 4 disk shelfs, 17 disks and its running OnTAP 6.2R2. The F630 needs more diskspace and no extra disk slots, so I've like to move one of the diskshelfs from the F760 to the F630 and add some spare disk to it. The diskshelf, which I planed to move, has 3 or 4 disks connected to it, so I must move disks internally on the F760. How do I do this with as little downtime as possible? Anybody that would like to share their experience with me? Thanks, Magnar
