RE: [Wlug] RH 7.3 ssh glitched after upgrade
by Martin, Eric Oct. 20, 2004

In /etc/ssh/sshd_config, uncomment the logging lines, and turn logging to debug. That will give you a lot more info. You'll want to turn it off after, as according to the sshd_config man page "Debug violates user's privacy". One thing that just happened to me as I'm typing this: ssh would prompt me for a login, but wouldn't log me in. No log of the event, just dumped me out. I sent SIGHUP to it and everything is fine now. I'm sure you've tried restarting, but weird things happen. Also, make sure that: UsePAM=yes AllowRootLogin = Yes In you /etc/ssh/sshd_config -----Original Message----- From: Dick Goodman [mailto:wlug@goodman1.net] Sent: Tuesday, October 19, 2004 8:32 PM To: wlug(a)mail.wlug.org Subject: [Wlug] RH 7.3 ssh glitched after upgrade I have four RH 7.3 servers which had not been updated for a loooong time.

Re: [Wlug] mounting a pen drive (usb)
by Ryan Caron Oct. 18, 2004

Oct. 18, 2004

Assuming you do not have any other usb devices hooked up to your laptop, adding the following line to your /etc/fstab will allow you to mount and use your pen drive as a non-root user: /dev/sda1 /mnt/sda1 vfat user,noauto,exec 0 0 Using this method, you will have to type "mount /mnt/sda1" when you insert it and "umount /mnt/sda1" when you are done. I cannot stress how important it is to unmount! Failure to do so will either leave your pen drive without the changes you made or with data corruption (I know this from experience) If anybody knows of a way for linux to mount automatically do this I am all ears (switching the noauto parameter to auto doesn't do the trick).

Re: [Wlug] mountng a pen drive (usb)
by Gina Minks Oct. 15, 2004

Oct. 15, 2004

= How do I get my SanDisk cruzer mini 256 mb pen drive to mount on my Fedora Core 2 laptop? Check to see if the pen has already been recognized by hotplug by checking for an entry in /etc/fstab If there is not an entry there, check to see if the OS recognizes the pen. Lots of places to check.. cat /etc/proc/scsi/scsi you should see: Attached devices: Host: scsi0 Channel: 00 Id: 00 Lun: 00 Vendor: SanDisk Model: Cruzer Mini Rev: 0.1 Type: Direct-Access ANSI SCSI revision: 02 or look for it in dmesg: dmesg | grep San Vendor: SanDisk Model: Cruzer Mini Rev: 0.1 or in /etc/sysconfig/hwconf: grep San hwconf desc: "SanDisk Corporation Cruzer Mini" usbmfr: SanDisk Corporation desc: "Sandisk Cruzer Mini" If the OS recognizes the pen, most likely updfstab does not have an entry for it. For RH9, entries for updfstab are in /etc/updfstab.conf.default This is the file hotplug uses to know what to write to the fstab file so you can mount the pen. I added an entry to the "flash" stanza: device flash { partition 1 match hd CompactFlash match hd ImageMate match hd SanDisk match hd "USB Drive" Once you add that, look in the fstab file to see if hotplug worked. You will still have to mount it, it should show up as /mnt/flash -Gina _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug ============================================================

Thanx for the info John. Unfortunately I can't use the Red Hat GFS, it requires v3.0 and we cannot upgrade to that yet. I have been pushing for it, but Oracle won't give me an definite answer as to whether their apps are certified for RH 3.0. We could go with Veritas' Storage Foundation for Oracle RAC, but that would require considerable change, and no one here knows the software. For the time being I'll probably have to go with a NAS device and make it as redundant as possible. -----Original Message----- From: wlug-bounces(a)mail.wlug.org [mailto:wlug-bounces@mail.wlug.org] On Behalf Of John Stoffel Sent: Wednesday, October 13, 2004 9:28 AM To: Worcester Linux Users Group Subject: Re: [Wlug] NFS question Don> I have an Oracle 9i RAC set up consisting of 3 database servers, Don> two apps servers and an EMC Clarion CX700 SAN.

Getting a NAS box which provides NFS service to the DB servers and which has the require reliability you need. I personally like NetApps, but they can be pricey. But even with a single head, they're reliable and run well. I had one box with an uptime of almost 500 days. Oh yeah, UPS and Generator backup helps as well. *grin* You could get away with using another cheaper NAS, but since you spent the money on the SAN, why not just use that and GFS to provide the storage you need. Esp if most of the filesystems you provide are read (mostly) then you shouldn't have many problems.

NFS question
by Don Peterson Oct. 13, 2004

Oct. 13, 2004

Hello All, I've been a slient member for awhile, now I have a question/problem I hope someone can answer. I have an Oracle 9i RAC set up consisting of 3 database servers, two apps servers and an EMC Clarion CX700 SAN. The servers are all running Red Hat 2.1, the db servers are at kernel .34 and the apps servers are at .49. I have 5 nfs mount points shared out by the first database server. One mount point is for logs from the database servers (only they connect to it), and the others are for miscellaneous files and storage. We have been doing failover testing, shutting down a database server and seeing if the other two keep processing requests. We have a problem when we shut down the first database server, the one sharing the nfs volumes. The other two servers just hang trying to connect to the shares. I have tried every option in my fstab file to make the servers stop trying to reach the nfs shares if the server is not available, but nothing has worked. Here is one of the lines from the fstab file where I mount a share: shoprod1:/applcsf /applcsf nfs soft,rsize=8192,wsize=8192,retrans=6,timeo=14,intr Can you see anything wrong with this line, or can anyone suggest something else to try. I can't even forceably unmount the shares with an umount -f. And if we try to kill any processes accessing the shares the kill command just hangs (even with a kill -9). Any suggestions? Thanx, Don Peterson Network/Telecomm Mgr. Sterilite Corporation

RE: [Wlug] NFS question
by Don Peterson Oct. 12, 2004

Oct. 12, 2004

I'm not sync'ing data, all three servers are writing logs to the share constantly (the applcsf share). We didn't buy Veritas volume manager, and we are not running Red Hat 3.0 yet, so I had to go with NFS for a shared file system. Believe me, I wish I didn't have to use NFS. I am looking into buying a NAS device to store the shares on, that way any of the servers can go down and the others won't be affected. But the NAS will still be a single point of failure. -----Original Message----- From: wlug-bounces(a)mail.wlug.org [mailto:wlug-bounces@mail.wlug.org] On Behalf Of Charles R.

I don't think there is any good solution. Using the "soft" and "intr" mount options is an extremely bad idea. Do it only if you don't care about losing/corrupting your data. Important data should always be mounted "hard,nointr". Personally, I avoid NFS like the plague. I only use it for readonly mounts (where soft,intr is less of a problem). Instead, I've standardized on rsync over ssh with RSA keys to get data between servers that need to be synchronized. _______________________________________________ Wlug mailing list Wlug(a)mail.wlug.org http://mail.wlug.org/mailman/listinfo/wlug

Internet service for newbies
by Patrick Sawyer Oct. 6, 2004

Oct. 6, 2004

This is in regards to the install fest that will be happening Saturday at the Worcester Computer Coop. These machines will be given to people with little computer experience / money. All they need for an Internet service is a very simple dial up. Has anyone tried Net zero for Lindows(linspire) and got it running under Linux? If not can someone recommend a good ISP. The cheaper the better. Thanks Patrick

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI everybody, We have a WLUG meeting coming up in about a week, and as usual, I'm searching for a topic at the last minute. I'll certainly give an update to the group on our work with the Worcester Computer Co-op, but that won't take the whole meeting. I can also discuss some issues in which I've been personally involved with regard to which license to use on free documentation that I have written, but again, that won't take the whole meeting. I'd rather have a single complete topic for the meeting, so if anybody has any ideas and (even better!) wants to volunteer, please let me know. Thanks!

SuSE Watcher

Hi All, I just installed SuSE Server version 9 (my first SuSE installation) and I'd like to use the "Watcher" to get updates automatically, but I can't figure out what the "autorization" window wants. I know it's looking for a username/password pair, but what username/password?? I don't recall creating one, other than the usual 'root' and various users. Is there a "special" username & password that I should've created? Thanks, Chuck
