You could as well create a blank disk image file, mount it as a loop device, format as encrypted xfs (or better, encrypted zfs), unmount and finally copy (dd or zfs-send) the image file on whatever medium you want. (I don't know much about xfs, but zfs has advantages for this purpose: snapshots, encryption, variable block size, ACLs, zfs-send directly to a file, etc). But, my point was that backups must be accessible at all times, covering the most use cases possible. So it means up to the most critical emergency situations, when you don't have a system at hand that can read a particular filesystem, but you must read/extract the data from your backup. Hence choosing the most universal FS.

Not quite. The file times are usually changed in the un-tar operation. You can usually expect to only have a valid m-time. In addition, extended attributes such as ACL are not preserved without some effort. There is a further problem in that the owner and group values may be different between systems The situation is much worse with NTFS on windows where there are alternative data streams and up to 16 timestamps per file per datastream. -- Jeremy (Lists)

So prefer FAT32/exFAT, and avoid ext4, ZFS, NTFS, APFS, etc. I do not want to further confuse this thread, but feel I must point out the fact that when a file is copied from one file system to a different file system (backup), the metadata may be translated. When the file is copied back (restore), the metadata may be translated again. The full-circle backup/restore results may not be identical. If the file is a some kind of archive (e.g. tar(1)), both the data and metadata are inside the tarball and the full-circle results should be identical. David

RiverWind wrote: Hey There, Note that cross-posting to a large number of lists never works out very well. I would hold discussions one at a time. I have chosen to reply only to the debian-user list since that is the list to which I am subscribed. I have two computers, a DOS and a Linux box. Now then, I am wanting to access my Linux box via my DOS box. When you say access, what exactly do you mean? In my mind that conjures up only one image. In my mind I would run a serial terminal emulator on the DOS machine and use it as a serial terminal to the GNU/Linux machine. Of course this has advantages and disadvantages. You old DOS machine probably has a serial port. Most of the older machines did. But your newer GNU/Linux machine might not. Most of the newer machines today are no longer providing those included as standard on the machine. However it is very easy to use a USB to serial converter. I have a couple of such converters on different machines and they work very well. Using one of those USB-serial converters you could easily set it up as a serial console to a machine that did not originally include a serial port. However that will only work once the operating system is loaded. It will not provide access to the BIOS nor to the boot time processes. I would ultimately like to use my Linux box as my sole ISP. This statement confuses me. Your machine is not an ISP. An ISP is an internet service provider. You would connect your machine to your ISP in order to have access to the larger, and notably hostile, Internet. Because this is something you connect to then you should be able to connect either your DOS machine or your GNU Linux machine to your ISP and you would only need one of them. How are you connecting to your ISP now? By using your DOS machine? How? By phone line modem? By DSL? By cable modem? Other? Broadband is the preferred connection and the majority of broadband users today connect using either a cable modem or a DSL modem. Most of us have happily left phone line modems and the sounds of phone line connections behind. I haven't heard a the bong-bong-chime-buzz of a phone modem connection for a very long time now. I do not believe that using my modem in order to dial up my Linux machine would work, but I also know that there is such a thing as a NUL modem cable??? This leads me to believe that you are using a phone line modem to connect to your ISP. True? Yes on the null modem cable. In RS-232 one wire is the transmit and another wire is the receive making the cable connections polarized. This is designed to talk from a computer to a terminal and each had their own polarity. A null-modem cable flips those so that two computers can talk directly without the terminals in the middle. This is the DTE and DCE classifications for data terminal equipment and data computer equipment. You would use a null modem cable to talk RS-232 serial between two computers. Or null modem cable adaptor. Radio Shack sells such an adaptor and as I recall it is around five dollars. With the adaptor any standard serial cable can be converted into a null modem cable. Your GNU Linux machine's /etc/inittab file contains a commented out template line to start a serial terminal getty process. Uncomment it. Send init the HUP signal or run 'telinit q' to have init re-read the /etc/inittab. That would be very old-school though. Surely there is a way for you to use your GNU Linux machine directly. Then you would not need to have a serial connection between them. How would you good gentles go about putting such a plan as mine into action? In other words, how would you go about accessing a Linux machine with a DOS system? Is there any special software? Would I have to use a USB port? If I am not mistaken, DOS doesn't work with USB ports??? Even more desirable would be the ability to use the terminal emulator Commo as my means of establishing contact between the respective systems. If your GNU Linux machine has a serial port then connect up a null modem cable between your two computers. Or use a standard serial cable with a null-modem adaptor to connect. On your GNU Linux machine uncomment the getty entry from /etc/inittab. The line to uncomment is the following line: T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100 That will start the getty process on the /dev/ttyS0 serial device. If you are using a USB-serial converter then the USB device will be different and that entry will need to be adjusted. For a USB serial device the name is something like /dev/ttyUSB0 and so the ttyS0 part would need to be changed to be ttyUSB0 instead. Here is an example for a USB device: T0:23:respawn:/sbin/getty -L ttyUSBS0 9600 vt100 Notice that ttyS0 has been changed in that example to ttyUSB0 for a USB to serial converter. The 9600 in the above represents 9600 bits per second, 8-bits, no parity. Then with the above getty in place and running you would start Commo on your DOS

Nagios : need some advice
Hello, I'm new user of nagios, and i'm not sure of everything i want to do. All is ok, but my boss (he give me a lot of trouble!) want to nagios do the service check faster (every 10second for example). So a lot of question come into my too small head : - Do i need to use another monitoring software? - Is MRTG(i'm think now it has a new name) could be useful for me? - Is this setup could be interressant for me : In the main configuration file, the unit of time is set to 10sec : timing_interval_lenght = 10 And the update of status : status_update_interval = 10 If i do so, i change my check_normal_interval for all my service in the service configuration file. And maybe i must change another option (but what options?) and is nagios will be happy to do as i want? Say me if you think that my idea is not so bad. thanks. nk.

The essential things to monitor is switch, gateway .. Bosses always appreciate - besides the uptime of your systems ;) - nifty graphs visualizing internet link usage or the like. I found cacti (www.cacti.net) to do a very good job at that. Most of the time you don't know whats going on on your systems or your network in terms of utilization. Cacti brings total transparancy to that and supports you in long term capacity planning and retrospective troubleshooting. It does not do alerting (like nagios), but does a perfect job at graphing measuring data (cpu load, memory / harddisk usage, link usage, ...). So it's a complement to nagios i consider worth using. Every 10 seconds can put a lot of load on your network connections especially if you monitor a lot of services and servers. I would certainly not do that for most of the servers/services. So i will set a fast monitoring only for things like cpu load. Do you think it is really necessary to monitor cpu load every 10 seconds? I don't. We check it at about every 5 minutes. Rather use tresholds to do a more frequent checking when you get in the range of a possible overusage. So normally check every 5 minutes but when you get to a repeated 5-min load of 1 (for a 1 cpu system), do a more frequent checking. It is a lot about figuring out whats the best procedure for you specific environment, but i definitly would not trigger a check every 10 seconds. - sebastian -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Bad DIMM? Need testing advice
Hi, I recently thought I'd take advantage of the low RAM prices and got some memory for my home machine (Athlon 900, Asus A7V). I bought two 256MB PC133-DIMMs specified for 2-2-2 timing. Being a bit on the cautious side regarding memory, I decided to run memtest86 which indeed reported some errors early on. I haven't had time to investigate any further, but I thought I'd post what I have so far and ask for advioce about my testing plan. Here goes: During Test 1 [Moving Inv, oneszeros, cached] a couple of addresses fairly close to each other (1e92e99c, 1e94a99c, 1e90a99c, 1e92699c, 1e91a99c, 1c93e99c, 1e94299c, 1e91a99c) were reported with errors. They all seemed to fail in exactly the same bit. The ouput was somewhat as follows Addr Good: Bad:4000 Xor:4000 I encountered 8 errors in 7 passes of Test 1, 6 of which occured in pairs (2 errors in same run, shortly after one another). 2 passes went through without any errors. As you can see above, no single address failed more than once. As I have absolutely no idea about the physical properties of memory, I'm somewhat at a loss interpreting this result. Does it look like a faulty chip or could there be some other reason? The memtest86 README mentions something about USB legacy support producing fake errors with some INTEL chipsets -- could something similar be happening here? FWIW, I have disabled USB legacy support. I plan to proceed as follows: - run the complete test (could anybody with a similar setup give me some estimate as to how long this would take? Also, do you deem it necessary to run the extended tests as well?) at least once, better twice and note which other tests fail. - swap the 2 DIMMs and rerun the tests that failed, noting whether the errors still occur and if yes, whether they occur in the same memory region. If that is the case, I'd suspect it's not a simple case of a broken chip. - test each DIMM separately to find out which one is faulty. Any comments, suggestions, advice?

Re: Bad DIMM? Need testing advice
I too have got a problem that's bugging me sometime now. Whenever I try to compile a kernel, or uncompress some big file, arbitrary characters get inserted in some files, leading to parse errors. For example, If I start compiling a kernel, it ends with a parse error. I check out, and find a ' or J inserted somewhere. I remove it, start compiling again, only to find another ' or J somewhere else. Another example: If I try to do a apt-get install something, then, a parse error in /var/lib/dpkg/status or /var/lib/dpkg/available occurs. Somewhere ' or J gets inserted, leading to parse error. I remove them, only to find them somewhere else. Now, I have got a cron job running every midnight to back up those two critical files. IF those errors occur, I just replace them with the backups. Now, what's the problem? Is it hardware problem? I think so. If it is, whom should i suspect - hdd/memory/cpu/cache/cables/ide whatever? I have discussed this in different mailing lists, but in vain.

Apache + Extras, need install advice
I wanna set up a web server w/ Debian, and I wanted to get some quick advice about that packages to grab and install. Basically, I want Apache, with SSL, PHP, and MySQL support. Also, I would like to have MySQL (obviously), and SSH (for secure access). Not really much else I want installed right now, just that, a secure, full featured web server. Can anyone point me to the exact packages? I noticed browsing the ftp directories that most of the stuff is there, but I notice some versions of apache have like one feature but not the others... And I would like to do it out of recent binaries for x86 rather than build it from source (just to save time). And, in addition to a list of the specific packages I would want to grab, any advice as to the specific places to grab them (which mirror for fast access in mid-west USA, and which directories if you happen to know), and which specific order to install them... I'm still digging, it shouldn't be all that hard, but I figure someone has probably done exactly this recently and might have a bit of advice. Thanks, Rob
