You can use `hexl-mode' in Emacs. To hex-edit a file use the `hexl-find-file' Emacs command. To compare the 2 files use `cmp' or `diff' on the output of `od -t x1 file`.

Re: running script after sftp upload

What I want to do is to run a script (on the server side) that after user logged in and uploaded a file. sftp-server man pages don't give any help about this issue. The `sftp-server' is a free program, so you can take the source and fix it any way you want. I wanted to check this so I downloaded the openssh source tar ball and looked at sftp-server.c . I found out that without any change, you can get a log message when the `sftp-server' close a file, this message include the file name and the number of bytes read and written. By watching this log you can do whatever you want after each action. Since these are informative messages, You must change the `sftp-server' logging level to INFO, by adding -l INFO arguments to the `Subsystem' command in the /etc/ssh/sshd_config file. If don't want the messages in the SYSLOG, you can add the -e argument and redirect the stderr (i.e ... -l INFO -e 2/dir/.../log-file). You can use a FIFO file when redirecting so you can read the messages by a program or script directly. (please note, every time the sftp session ends, there is an EOF on the reading side, so you must restart to read).

Re: The riddle of atomic data transfer from process A to process B

I forgot how this scheme is called, but assuming you have some shared memory between the processes, what you do is: have value variable (e.g. value) and counter variable (counter) also shadow_value and shadow_counter initialize counter to 0 (any even number will do) in process M: atomic_increase counter; (or follow with memory_barrier()) write value; atomic_increase counter; (or follow with memory_barrier()) in process A: pre_counter = atomic_read counter; (or precede with memory_barrier()) new_value = read value; post_counter = atomic_read counter; (or precede with memory_barrier()) if (pre_counter == post_counter) (pre_counter%2 == 0), new_value has been safely read; write it to shadow_value, use that as value, (and for good measure store pre_counter in shadow_counter). if pre_counter != post_counter, use shadow_value - and be aware that your value is actually up to date only for shadow_counter. This scheme has some flows as Omer has noted. Let me propose somewhat different scheme based on the same principle that I think will work. Use shared memory segment that include: an index (byte or word) First array of N (N = 2) values to pass. Second array of N (N = 2) values to pass. Process A (the sending process) write the K (K=0...N-1) value to the 1st and 2nd array than it updates the index to K. Process B does: Reads the index save it (I). Reads the value I from the 1st array and save it (V1). Reads the value I from the 2nd array and save it (V2). Reads the index again (I2). if V1 = V2 and I = I2, use the value, otherwise redo from the top. This process ensures that B never gets a wrong value, but if A is too fast, B will never get a value.

How to do grub-install on a (non loading) virtual guest
I had problems with repeated virtual guest crashing and the grub boot loader destroyed. I found a way of doing grub-install to the virtual guest (a file, not a partition) on Centos5 host. I hope it may help anyone with a similar problem. 0) Ensure the virtual machine is not working (use `xm list' to check). 1) Mount the virtual disk (cooked file) on loop device. I use the `loop7' device because other loop devices may be used by working virtual guests. losetup /dev/loop7 virtual-guest-file 2) Add all the partitions to the device mapper: kpartx -a /dev/loop7 3) Mount the virtual root partition: mkdir -p /mnt/virt mount /dev/mapper/loop7p1 /mnt/virt 4) Check the Major/Minor values of the mounted devices ls -l /dev/loop7* /dev/mapper/loop7* 5) Work in as root partition: chroot /mnt/virt 6) create /dev/hda and /dev/hda1 devices: mknod dev/hda b 7 7- Major/minor of /dev/loop7 mknod dev/hda1 b 253 0 - Major/Minor of /dev/mapper/loop7p1 7) Fix the grub by re-install: grub-install /dev/hda 8) Exit the `chroot' jail exit 9) Unmount the virtual root partition: umount /mnt/virt rmdir /mnt/virt 10) Clear the /dev/mapper partitions: kpartx -d /dev/loop7 11) Release the loop device: losetup -d /dev/loop7 Now you can restart the virtual guest: xm create virtual-guest-name Ehud -- Ehud Karni Tel: +972-3-7966-561 /\ Mivtach - Simon Fax: +972-3-7976-561 \ / ASCII Ribbon Campaign Insurance agencies (USA) voice mail and X Against HTML Mail http://www.mvs.co.il FAX: 1-815-5509341 / \ GnuPG: 98EA398D http://www.keyserver.net/Better Safe Than Sorry ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Filter your RTF with the sed command bellow, it will drop the boxes.
Than run catdoc as above or use open office (I used `ooviewdoc') both

Well done, you nailed it. Placing an explicit call to exit for the child process solves the segfault. I hope you used _exit() and NOT exit(). The man page on my system for vfork says (read carefully, at least 3 catch you): vfork() differs from fork() in that the parent is suspended until the child makes a call to execve(2) or _exit(2). The child shares all memory with its parent, including the stack, until execve() is issued by the child. The child must not return from the current function or call exit(), but may call _exit(). Also note that vfork on GNU/Linux stops the parent until it exit by either calling _exit() or executing execve(). Normally (in older systems) it was used solely to execute another program. BTW. On linux, If you do execute a program right away, vfork is not really better than fork. On older systems (e.g. DG/UX) fork copied the whole memory before continuing, and vfork changed the shared (read: parent) memory. On linux fork use copy on write so it does not copy (almost) any memory before doing its work.

What's wrong with `locate' (beside it is not being updated during the
day ?). You can wrap it any way you want, it has regular expression
search, and it is fast. I use it both in work (over 3.5M files in 69K
directories) and at home (~900K files) and it works fine.
For example, here is the function I use to search my home media:
lct ()
{
RSRC=`echo $@ | tr .`;
echo locate -i -b -r '$RSRC';
locate -i -b -r $RSRC | grep -E (/media/[msf][oui][vbl])|(/ehud/tmp)

The above can be written without the extended grep:
lct ()
{
RSRC=`echo $@ | tr .`;
echo locate -i '$RSRC';
locate -i --regex ((/media/[msf][oui][vbl])|(/ehud/tmp)).*${RSRC}[^/]*$
}

Right now I'm not working on a Mozilla plugin (I'm writing a plugin for net-snmp agent, which is less anal about such things), so a link is neither necessary nor particularly important. When writing Mozilla plugins, the problem is not creating the links (running make install create those links with no extra work). The problem is that mozilla does, roughly, the following: - Scan all files in the plugin directory - For each file: As long as the type is symlink, resolve where it points to. - Check whether the file name ends with .so So the above plan (link from .so to the real name) will simply not work. Please don't ask me why that is what Mozilla does. Shachar, I suggested a real (hard) link, not a symbolic link. The -f was to ensure re-linking even if the target exist.

That's a big advantage if you ask me. What's a killer argument against LVM2? instability in the old kernels, multiple snapshots mean multiple COWs (which zumastor is built to solve). people here wanted hourly0,1,2 and daily0,1,2 AND weekly0,1,2. that means 9 growing snapshots at any given moment, and that is one very serious disk handicap. snapshots in LVM2 are not really designed for that, they were mainly meant to be for hot backups of file systems, so you can freeze the FS just long enough to snap the state to a tarball and remove the snapshot. You don't want many snapshots because of the heavy load penalty (each write is multiplied by the number of snapshots). If you have enough disk space you can create pseudo snapshots by using hardlinks between the snapshots so only changed file takes space. It really depends on the file size distribution - few large files that change constantly will defeat this concept, while many small files is ideal for this scenario. I use this approach and keep more than 60 snapshots of 350 GB disk on a 700 GB disk. The whole process is very simple: Initiation: copy the whole disk (or an LVM snapshot of it) to the destination disk in a SUBDIRECTORY (eg `cp -a'). For each snapshot: 1. Check the size left on the snapshot disk and remove old snapshots until you have predefined minimum space. 2. Copy the subdir (hardlink only) to a new subdir (I use `cp -al'). 3. Create an LVM snapshot of the original system. 4. Sync the copied subdir with the real LVM snapshot (`rsync'). 5. Remove the LVM snapshot.

So I decided I want to upgrade from FC6 to Centos 5. I was wondering if anyone did it and if so, what method? what are the gotchas that I need to be careful of, or is it simply better to keep my data out, format the machine and install centos 5 from scratch? (Centos 5 does not recognize Fedora stuff, so the upgrade option is not given). Think twice before you go the Centos way. I use both FC (now Fedora without `Core') and Centos in the office. Both work fine and I don't update the production machines (there is no access from the Internet except for mail and ssh). I installed Centos 5 on my home server and I update it frequently. But Centos 5 is not for home use - its distribution does not have media programs (like LVM, I wanted it for media streaming). So for home/media use, may be Fedora (now 8) is better for your needs (few RPMs are available for Centos on ATRPMS, FreshRPMS does not support RHEL/Centos at all). Ehud. BTW.

I agree that CentOS is usually not good for home.

You can add -- before the file name, this signals mv/cp/ln/rm that all the options has been processed, and file name(s) follow. This is the prefered way - that's why it was built into the file commands. e.g. mv -- --test test to delete a file named -- do: rm -- -- 2. You can add directory specification to the file name and so it won't start with -, any file can be written as ./file . e.g. mv ./--test test Any way that will make the 1st file name NOT to start with - will work. e.g. rm -f dummy-name -file-1 --file-2 Ehud. -- @@ @@@ @@ @@ Ehud Karni אהוד קרני @@ @ @@ @ Senior System Support תמיכה במערכות מחשב @@ @@ @ @@Mivtach - Simon מבטח - סימון @@ @@ @@ Insurance agencies סוכנויות לבטוח Better Safe Than SorryTel: 03-7966-561 :טל Fax: 03-7966-667 :פקס http://www.mvs.co.il mailto:[EMAIL PROTECTED] :דואל Ehud Karni Tel: +972-3-7966-561 /\ Mivtach - Simon Fax: +972-3-7966-667 \ / ASCII Ribbon Campaign Insurance agencies (USA) voice mail and X Against HTML Mail http://www.mvs.co.il FAX: 1-815-5509341 / \ GnuPG: 98EA398D http://www.keyserver.net/Better Safe Than Sorry To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

What do I save and where do I put it to use it. You have to do 2 things. 1st, you have to change /etc/yum.conf `keepcache' option to 1. For full description read the man page for yum.conf . 2nd you'll find the yum cache in the above file at the `cachedir' option (default to /var/cache/yum), just copy the whole directory, it includes all the headers and rpms loaded.

Entering Hebrew (2nd round) - VNC with twm
Hello gang, After reading the 1st round of entering hebrew? I have similar problem for the gurus of this list. I'm interfacing with Linux through VNC, i.e. I have a virtual screen created by VNC, with twm as the windows manager. The OS is as old as RH7.3 or new as FC6. I connect to the Linux box by ssh (from anywhere, mostly my home or office), which has a tunnel for the VNC. Most of the time I run only one application - Emacs - which is run as full screen without border or title. I don't need any Hebrew support for the Emacs - it is all done from within (by my hebeng.el). From time to time I need to run a Firefox or OO (to read HTML mail and documents), sometimes I'd like to run/test some legacy programs that run on xterm/rxvt. For the Firefox/OO I need UTF-8 Hebrew, for the legacy programs I need ISO-8859-8 Hebrew. So it all come to this: How I can manage the keyboard to produce English (upper lower case), Hebrew (UTF-8 and ISO-8859-8) with twm ? I prefer to have all those together (modifiers for Hebrew - like shift and lock for upper case). I have my practical solution, but I wanted to here from the list gurus their suggestions.

Nothing, you were correct in what you said. rsnapshot does not do real snapshots. It's just a very comfortable frontend to rsync. If you need real snapshots in linux you can use lvm. Not as convenient I did not know about rsnapshot. So I built a system that does exactly that (system of snapshots) with a simple sh script and use of rsync. I freeze the source file system by using the LVM2 snapshot (I need only 1 snapshot, which you can do with LVM1 too, for the duration of the rsync). I do this twice daily. An FS of about 250GB has about 90 snapshots on a 600 GB space. The snapshot process is very simple: 1. Copy the the latest snapshot to a new directory by `cp -al'. That is the real trick, it takes about 200 MB for the 250 GB FS (less then 1/1000), this takes about 8 minutes here. 2. Freeze the source by making an LVM snapshot, and mount the snapshot. 3. Use rsync to sync from the mounted frozen source to the new created destination dir (this takes about 20-25 minutes). 4. Unmount the LVM snapshot and remove it. That's it ! In real life I do steps 2, 3, 4, 1 so I don't have to wait at the start of the process. Step 3 is really many rsync parallel processes. The advantage of this approach is that you can have as many snapshots as you want (and have space for them) and the OS don't serv them. The LVM snapshots are very expensive to the OS, a single write can be multiplied by the number of active snapshots, if the overwritten block is in all of them.

therefor is supposed to need a backslash before it if used literally.
I'm not saying you are not right, just that it's strange that this is
the case.
Shachar, you wrong. Gilad wants the `diff' program to see $ID not
\$ID which is what '\$ID' gives to the application (diff does not
substitute $ID with its environment value, bash does it).

Last time I checked, $ in regexp meant match end of line. '$Id' would mean, if I understand this correctly, an Id coming AFTER the end of the line (an impossible combination, I know, but still). If I want grep to understand a literal $, I need to pass it a \$, which I can do either by doing \\\$Id or '\$Id'. I stand by my original statement. You are right. I'll say it again: YOU ARE RIGHT ! I take my statement back. I think a better way to pass the $Id would be '[$]Id' then you don't have to mess up with who is eating the backslash (and how many of them).

Re: Upgrading from samba2 to samba3 - Hebrew issues

The problem begins with the fact that Samba2 is not Unicode aware, thus, when you saved a file with an Hebrew name from a windows machine - the real file name on the storage was with the same character set as of the windows (CP862). When upgraded to Samba3 - the engine of samba3 in the back end expects the file to be in Unicode. With a modern Linux the solution is simple: add the statement unix charset = cp862 to the [global] section of smb.conf [Solaris vs. Linux discussion and solution snipped] Bellow is my Samba (3.0.4 soon to be upgraded) configuration.
