RE: [Wlug] RH 7.3 ssh glitched after upgrade

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 18 Oct '04

18 Oct '04

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).

Jeff, Thanx for the continued feedback and suggestions, RHCM sounds cool but, I've read through some of the bug tracks on it and it sounds like there are some bad corruption problems when using it.

Re: [Wlug] mountng a pen drive (usb)
by Gina Minks 15 Oct '04

= 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 ============================================================
