SCSI emulation in Red Hat 7.2?
by author 09 May '02

Does Red Hat 7.2 have SCSI emulation in its kernel or do I have to install it myself? This is for burning CDs with cdrecord. For some strange reason, cdrecord only works with SCSI.

According to author: > Does Red Hat 7.2 have SCSI emulation in its kernel or > do I have to install it myself? > This is for burning CDs with cdrecord. The ide-scsi driver has been included as a kernel module at least since RH 6.2, and auto-detection and configuration of an IDE CD-RW drive has been in the installer for about as long too. > For some strange reason, cdrecord only works with SCSI. Yeah, that may be just historical, since most of these devices were only SCSI-based at first, and there was reasonably flexible support for them using the generic SCSI driver (sg) in the kernel. The ATAPI (IDE) drives implement essentially the same SCSI command set, so the ide-scsi driver was a simple and reasonable kludge to get them to work without having to rewrite a whole bunch of applications. -- Gilbert E.

MUUG Meeting, May 14, 7:30PM -- OpenBSD Installation
by gedetil＠cs.umanitoba.ca 07 May '02

07 May '02

[Posted to man.unix.general and other news groups] ------ Forwarded Article <ab9idc$n7d$3(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, May 14. The meeting topic for this month is as follows: OpenBSD Installation Did your Linux machine just get hacked? Do you want to run an operating system that hasn't had a remote root exploit in four years? Try OpenBSD. It runs on Alpha, Intel, most Macs, SPARCs, and more. It has binary emulation for most UNIX operating systems including SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX. Shawn Wallbridge from Synack Hosting and Chris Lawson and Sean Cody from Tin Foil Hat will be installing OpenBSD 3.0 on a machine and explaining the process. They will explain the ports system, how to use it and talk a bit about packages, and finally how to keep the system up to date including CVS and patches. The group holds its general meetings at 7:30 PM on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our new meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15 PM, so the meeting can start promptly at 7:30 PM. Don't be late, or you may not get in. Limited parking is available for free on the street, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable". If you're not already on these lists, we encourage you to subscribe now: http://www.muug.mb.ca/mailman/listinfo/ The "muug-announce" list is used for monthly meeting announcements (such as this one) as well as other important announcements of interest to MUUG members. The "rountable" list is meant to be a forum for follow-ups to topics discussed at the meetings, or for round-table-style discussion on other topics that come up between meetings. Of course, for this to be effective, we need to reach a certain critical mass. So, please subscribe, and stay involved! -- Gilbert E.

Win2K Administration reference.
by Brock Wolfe 02 May '02

02 May '02

<FLAME FORCE FIELD> Having at least a minor grasp on Linux Server administration, now the evil dark forces have thrust Win2K upon me to look after as well. Since it is such a rare beast, is there a single book that is THE reference on Win2K administration (network services configurations, task automation, etc) ? I have looked at O'Reilly, MS handbooks, etc. Any testimontials from those supporting mixed servers on a network ? </FLAME FORCE FIELD> Brock

Server config
by Brock Wolfe 30 Apr '02

30 Apr '02

I am looking at building a high reliability, fault tolerant file server to store 300 plus GB worth of files. Reliability is needed b/c a sysadmin will not always be around/on-site to ensure full backups are made regularly. I am assuming RAID 5 array, for data and seperate drive(s) for OS (RH 7.x), redundant power supplies. Any suggestions (voice of experience) on: - Motherboard/CPU combo's - Server Cases - RAID host cards (3ware-IDE, Mylex-SCSI) - High(er) MTBF IDE, SCSI Hard drives (I don't want another 60/75GXP fiasco) <g>. - Tape drives (DLT, DAT, etc) Thanks in advance for any words of wisdom.

Managing/Growing Disk Space under Solaris
by John Schulz 30 Apr '02

30 Apr '02

I trying to configure some new storage under Solaris (2.6/8) and wonder if people would have an opinion of which of the following two solutions would be best. I don't have any fancy tools available (like Veritas) and am trying to do this using basic Solaris tools. I'm adding large disks (181GB mirrored with hardware RAID) and would rather that the users not see that they have all the space before I think they need it. We all know that any free space will always be filled when you add new disks. Possible solutions: 1) When you create a filesystem under Solaris you can set a minfree percentage. This percentage (10% by default) of diskspace is kept reserved by the O/S to optimize filesystem usage. This percentage can be changed on the fly with "tunefs" and I was thinking I would start at 60% minfree (40% of disk availabe to user) and increase as necessary. This tunefs change can be done on alive filesystem. 2) It is possible to grow (add sectors) a ufs filesystem under Solaris. When you create a filesystem with newfs you can tell it to use less than all the sectors available on the partition you have specified. You can then grow this filesystem to the max sector count of the partition you are using. The filesystem doesn't need to be unmounted but become read-only during the grow. I believe this was added to support Disksuite objects but also works in ordinary partitions. So, has anyone experience with either of these?

G'Day, Thank you for the suggestions. The server is using the ext3 file system. It appears cpio does not support files greater that 2G. If I tarball the structure, the system has no problem. sean "Peter C.J.

large file support
by S/C Conway 25 Apr '02

G'Day, Does anyone have a good links to information on turning on LFS (large file support). I wish to create files greater than 2G on a RedHat 7.2 install, it doesn't permit at the moment. I have had little success crusing the net. Does anyone have a pointer? Sean

Linux on MTS ADSL
by Brian Doob 23 Apr '02

23 Apr '02

I just moved to an apartment where I'll be getting MTS ADSL (Shaw High Speed is not available). How do I set up Linux to use it? I know you need to use PPPoE, but I don't know how to do that. I have heard that you need to make other adjustments to take proper advantage of it. I'm getting "Starter DSL" (to start with), but I don't think that makes a difference. I'm currently running both Red Hat 7.2 and Gentoo 1.1a. How do I set things up? Thanks. -Brian

X remote login
by Ihor Jakowec 17 Apr '02

17 Apr '02

I would like to login to the University of Winnipeg's mainframe, with an X window interface, from my personal computer at home. Up to now I have just been logging in with telnet ( in text mode). Remote login in to the University of Manitoba's computer can be accomplished with just a one line command. However, this does not work with the University of Winnipeg's machine. I suspect that an xconfigure file or possibly environment settings could be required, either for my home machine or on my account at the University of Winnipeg (or at both places). Are there any recommendations as to how I can remote login (with an X interface), to the University of Winnipeg? -Ihor
