Does the Secure Administration option (i.e., ssh) for filers support scp to copy the /etc/passwd file across, if you're using quotas? -----Original Message----- From: Keith Brown [mailto:keith@netapp.com] Sent: Tuesday, August 08, 2000 4:39 PM To: Jiang, Perry; toasters Subject: Re: NetApp questions > Do I have to create an Oracle account on NetApp Filer > and put the entry in /vol/vol0/etc/passwd? You mean *by* putting an entry into the filer's /etc/passwd file, right? It's always a good idea to keep a filer's notion of /etc/passwd file entries in sync with the rest of your network, but strictly speaking it's not often necessary for basic NFS operation. In fact I am told that in the early years of NetApp, before my time, filers didn't have /etc/passwd files at all. The NFS protocol just deals in UIDs and GIDs, and back then the filer had little need to know what user names and group names were associated with those numbers. These days, there are features in the filer can benefit from knowing about username/UID correlations. The quota subsystem is one that springs immediately to mind. If you have used usernames in your /etc/quotas file for example, the filer needs to know what UIDs it should be looking for in the file system in order to charge space to the specified users quota. The Windows file service networking is another subsystem that can, in certain configurations, make extensive use of /etc/passwd (oddly enough! :-)), although it is also worth pointing out that day-to-day administration of a passwd file is entirely unnecessary when a filer is deployed in a Windows-only environment. So, in summary, in a UNIX environment, I would make a habit of keeping the filer's /etc/passwd file in sync with the rest of the network as a matter of good practice, even though it may not be absolutely necessary. Don't forget that there is NIS client support in a filer to help you out in this area. Keith

RE: move command on filer?
by Agnew, Blaine 09 Aug '00

NDMPCopy can be handy for this sort of application, however I don't know if someone has ported it to NT yet. It is a freeware utility that runs on the host and controls the filer via NDMP commands. It is similar to having a dump piped through to a restore, except that the data does not have to go through your host. You can get the source from www.ndmp.org if you want to get more information. -----Original Message----- From: Muhlestein, Mark To: 'Nick.Mayrath(a)envoy.com'; toasters(a)mathworks.com Sent: 8/8/00 4:23 PM Subject: RE: move command on filer?

This weekend I need to move alot of files around of my F720. Is there any "move" command locally on the filer that I can use instead of using my NT machine? My concern is that using the NT machine will cause the moves to take longer since they have to "pass through" my NT box. Thanks

NetApp questions
by Jiang, Perry 09 Aug '00

09 Aug '00

Hi, there I have a question regarding NetApp Filer 740. Oracle account I am running a Solaris Oracle server, which is a NFS client of the NetApp Filer. Do I have to create an Oracle account on NetApp Filer and put the entry in /vol/vol0/etc/passwd? If yes, what the purpose of that? An on-line NetApp document, "Oracle for UNIX: Integrating with a NetApp Filer", stated that you need to create an Oracle account on Filer. However, according to the System Admin. Guide, /vol/vol0/etc/passwd is only for CIFS, not for NFS. You explaination is appreciated. Perr Jiang

Dear Reader, does anyone have experience with Quick Restore from www.worksta.com ? I would appreciate if there is anyone who wants to bring me up to speed where the caveats are ? I define caveats as pro's and cons as well as restore performance considerations Thanks a lot Klaus

Filer Performance in a CIFS environment
by Mike Hopkins 08 Aug '00

08 Aug '00

I know this is a generalized question where the answer is shaped by a basketful of variables, but I need to start somewhere. I have a Filer 740 that I am using to store files for a Win2000 web server. Pages served up by this combination of hardware are noticeably slower(5 to 10 seconds versus 1 second) than storing the web content on the local drive of the web server. This may not seem like much of a slowdown, but people notice these things and it is a big issue. So, what are some of the things that cause performance hits in a CIFS environment. Any suggestions, war stories, magic potions, or good old fashioned know-how is greatly appreciated. Mike Hopkins Broad Daylight, Inc.

RE: W2000 CIFS login problem DOT 5.3.5R2P2
by Jankowski Ted-CTJ012 08 Aug '00

This seems to be a bug with SP1 for win2k. It was working fine for us until then. NetApp has a dubbed it a bug, #28491, but the web page hasn't been updated with any info. I don't know how long it takes for the web page to be updated. I don't think they've determined who is at fault. -Ted -----Original Message----- From: Steve Losen [mailto:scl@sasha.acc.virginia.edu] Sent: Monday, August 07, 2000 11:41 AM To: toasters(a)mathworks.com Subject: W2000 CIFS login problem DOT 5.3.5R2P2 I was wondering if anyone else has seen this and if they know whether it is a problem with W2000 or DOT 5.3.5R2P2 We are using unix authentication for CIFS logins, so W2000 is set up for logging into a samba server. It works fine on a samba server but we are having problems with the filer. We turned on CIFS login logging to /etc/messages and the problem is obvious. The first character of the loginid is missing in the log message. I don't know if the PC or the filer is losing it. We'll have to set up a sniffer to find out. Has anyone else seen this one? I'm on NOW looking for this bug. If I don't find it, I'll open a case. There was an earlier bug where W2000 could not login to CIFS with unix authentication, but that is fixed in 5.3.5R2P2. Perhaps it wasn't completely fixed. We are having no problems with CIFS logins from NT, W95, and W98. (Have to enable clear text passwords, of course.) And I'm pretty sure some folks have had success from W2000, so this probably does not happen to everyone. Steve Losen scl(a)virginia.edu phone: 804-924-0640 University of Virginia ITC Unix Support

RE: What about SSH
by Philip, Nicolas 08 Aug '00

Jay, You are right only the password authentication mode is supported. But I am not sure what I mentioned implied the use of authorized_hosts? Once the session key is generated and encrypted by the client (using the RSA public key of the server), the server receive it and decrypt it using its private key. Then user authentication takes place. Please let me know directly if the use of an authorized_hosts file would work better for your environment. Hope this helps. Nicolas. -----Original Message----- From: Igor Schein [mailto:igor@txc.com] Sent: Tuesday, August 01, 2000 4:31 PM To: Philip, Nicolas Cc: toasters(a)mathworks.com Subject: Re: What about SSH On Mon, Jul 31, 2000 at 04:44:18PM -0700, Philip, Nicolas wrote: > Jay, > > Mike is right, SecureAdmin 1.0 is a product sold separately that installs a SSH > server (Secure Shell protocol) on your filer running Data ONTAP 5.3.x.

Hmm, when I was testing SecureAdmin, I determined that it supports password-only authentication. I called support and they confirmed it. If you're saying it's not so, then I should be able to create authorized_hosts file on the filer, right? Where would it be located? Thanks Igor
