For the record, netatalk is available for some other UNIX platforms besides linux as well. Solaris and Ultrix, for example. -----Original Message----- From: Braunschweiger, Udo [mailto:udo@netapp.com] Sent: Thursday, September 06, 2001 12:49 AM To: 'Maglinger, Paul'; 'toasters(a)mathworks.com' Subject: RE: Looking for Macintosh users Hello Paul we also have some customers in Switzerland which are using MAC's with Filer.

Advantages: With an existing Windows Domain, no other authentication method and maintenance of user accounts is necessary. No other license (beside CIFS) for the filer is needed.

If there is some good Unix-Know How arround, you can buy Ethershare from Helios ( www.helios.com <http://www.helios.com> ). It usually runs on solaris platforms and can provide File- and Print-Services for Macintosh. If the clients handle big picture files (to create Newspapers), the Ethershare offers some interesting features to improve the performance over the network. The other solution is based on Linux. The shareware netatalk also provides good performance on File-Services for MAC. You need a good level of experience with linux. If you can wait some weeks and take the risk to upgrade your Mac-Clients with an very new OS-release, you can use MAC OS10 to connect with nfs or MAC OS10.1 to connect with cifs. But maybe your applications does not run on this new releases. I hope, i did not increase the confusion.........

Hello, feedback from a customer: in the past they used helios, but they moved to xinet ( www.xinet.com ). The performance is execlent and you can use the Snapshot-Feature from the NetApp Filer. Xinet is running on a Solaris-client which has mounted the Filer. The Solaris-box exports the mount via xinet to the Apples. Ciao Phil

Save your money. My company has been supporting a dozen+ Mac users by running Atalk on a couple RedHat Linux boxes and letting them translate between NFS and AppleTalk. It's deceptively simple to setup Atalk and all the users have to do is select the Linux boxes thru their chooser. WARNING: Using this method we've found some Macs have an odd, ocassional tendancy to put funky date-time stamps on files. I've seen dates ranging from 1917 up to 2031. Needless to say, this causes some problems with our Solaris backup server. Hey, it's a free solution and simple shell script on the Linux box can find these files and change the date. (Although a better solution is to keep the Macs off your network completely! Macs are great but my experience is that they cause far more problems than they are worth.)

If they're up to OS X, it supports NFS. If not (and they can't/won't upgrade), then Dave is a proven work around. There are plenty of referenceable (sales jargon) Dave/NetApp customers.

Re: Unexplainable unresponsiveness of F820
by Kerry Schwab 05 Sep '01

When I have run into the bug, it didn't seem to have anything to do with how busy the filer was. It *did* seem to be related to pending output on the telnet connection. So, if you connected, ran a command, and then closed the telnet connection while the filer was still sending results, the filer would freeze. Another scenario is when "console log" messages randomly stream from the telnet conneciton. Closing the connection while the console logs message is being written triggers it also. It interesting that you mentioned "Big Brother", because I never hit the bug while actually typing interactively via telnet. It was always via some automated telnet connection ( Expect, Perl, etc). I guess a human typing always tends to wait before sending the <ctrl-D>, while the scripted connections aren't anticipating "extra output". == Kerry >>> <mcope(a)isisph.com> 09/05/01 04:46PM >>> Kerry, Thanks for the info. I use Big Brother (bb4.com) to monitor the Filers. One of the things it does every 5 minutes is open and close a telnet session to test telnet. It's a pretty ugly method because it just kills the telnet session as opposed to closing it. The problems on the previous Filer only manifested when it was getting hammered. I've been using Big Brother for a number of months now and haven't had any problems keeping telnet sessions open to a Filer. However, I can imagine where this could be a problem if the Filer is really busy and then one of these ugly telnet checks occurred and pushed it over the edge.
