SCSI schizophrenia
OK - I only have one tape drive but a real problem these days backing up.

Disable specific LUN on a SCSI bus
Hi all, do you know if there is a way at boot time do disable specific LUN's on a SCSI bus of a particular controller? I'm trying to write an udev rule, but it seems that the system ignores the "vendor" model/name of the controller... For example: I want to disable /dev/sdb; so I gather some information with udevinfo -a -p /sys/block/sdb and I try to use them to write

Make sshd log IP addresses, not hostnames
Can I adjust the ssh daemon to log IP addresses instead of hostnames? I assume this situation is feasible... * 10.10.10.10 attempts to ssh to the server * reverse dns resolves to "somehost.domain.com" * ssh daemon logs "somehost.domain.com" in messages * foward dns on "somehost.domain.com" resolves to 10.10.10.20 Thus it causes some of my scripts a problem if the

SCSI drives and Centos 7
Everyone, about 4 years ago, I tried to install CentOS 6 on a Supermicro server with SCSI drives using a LSI raid system. I could never figure out or find a way to make the installation disc of Centos 6 identify the SCSI drives. The installation disc for Centos 5 identified the SCSI drives without a problem. I finally gave up on Centos 6 and installed Centos 5 and the system has worked very

5.1 Upgrade Not Working?
So both "yum upgrade" and "yum update" now are complete and there's no new packages. However, when I attempt to check my version, I'm still showing 5. # cat /etc/redhat-release CentOS release 5 (Final) I remember seeing 5.1 repositories being access for the upgrades. Is it possible my system did not upgrade? # uname -r 2.6.18-53.1.4.el5.centos.plus Thanks, Scott

Changing ext3 Partition Size
I have an ext3 partition from our SAN. The size was increased. I am attempting to re-size this specific ext3 partition, obviously. I unmount the partition, run fdisk, change the cyls, and save...

How to move my MBR
I removed an ATA drive (/home) for a new SATA and my system would not boot. I'm guessing that it put the MBR on that drive instead of the drive that holds the / partition. What's the best way confirm where the MBR resides and, after I verify that's my problem, how I can move (or make a copy) onto a different drive? Thanks, Scott

how to rescan serial ports without reboot
Hi all, I hope this is possible. I have a server, with a network switch attached to the serial port, and I want to rescan the serial port (/dev/tty) to see if it picks it up? I'd prefer not to reboot the server if at all possible. dmesg reports ttyS0 as the active port: [root at zabackup01 ~]# dmesg |grep tty Bootdata ok (command line is ro root=/dev/System/root rhgb quiet xencons=tty6)

Xen on Dell PowerEdge 1850 with Perc 4e/Si controller
Hello, I am having issues making my box boot with Xen. I am working with linux-2.6.16.28-xen on a gentoo box. The server is Dell PowerEdge 1850 with Perc 4e/Si, FW 521X. When dom0 reaches the point of scanning the SCSI controllers, it hangs in a loop aic7xxx_dev_reset_returns 0x2002. My regular (non-xen) kernels come up fine with detecting my adaptec scsi controller.

Rescan for new geometry without reboot?
Hello, We just had our servers fitted with more disks. Most of the disks are growing existing RAID 1+0 channels, some are in new channels. Controllers and disks support live installation. I'd like to avoid a reboot just to let the system find that the disks are larger. All I can find so far suggests that its possible to rescan the disks, and even find the new geometry (e.g.

My G729 problem re-visited
Ok, I built a test system to duplicate my problem and provide myself a platform that I can mess around with to try and break any features. My problem is G729 pass-through from a gateway to a phone. I think I even have transcoding working, which makes me more confused on what's wrong with my pass-through. It must be a configuration issue. The basics... *CLI> core show version Asterisk

sdc1 without the sdc
So I'm working with the iSCSI Initiator and an EqualLogic SAN. I'm not sure when this might have happened, but it appears that the /dev/sdc device is missing, yet the /dev/sdc1 partition exists AND is mountable. Is there a method to re-create the /dev/sdc device? I cannot dd or fdisk it, obviously, but I can mount the /dev/sdc1 partition and it works just fine. Not having the /dev/sdc

Mapping to Samba
Using GUI methods (read: easy for most users), is there a way to map to a Samba share and have it accessible to all applications? Going through Nautilus I'm able to create a link to the shares, but they're not accessible from many applications. And, obviously, this is going to be something that changes per user (different mappings, different credentials, etc), so I can't use a static
