I heard dvddistaster does this, but I guess it is limited to DVDs. It would be great fo find a general data redundancy tool. In the moment, with the tools I know, the best I can do is store the files twice, with md5sums/shasums to decide which version is correct. Have a look at app-arch/par2cmdline ( http://parchive.sourceforge.net/ ). It will create parity files for an arbitrary set of data files and you can choose your level of redundency (from 0 = now redundency, just integrity checking, up to 100%). Although expect your parity files to be on the order of the percentage for size, i.e. 50% redundancy for some given files to take about 50% of their size for the parity files). The down side I find with the tool is that it doesn't currently support directories. This isn't so bad for creating parity files, but during checking/restore, the program expects all files to exist in the current directory, despite which sub-dirs they were originally in. You can get around this with a tar/rar/zip first, then calculate parities on the archive though. Thank you very much. I have taken a quick look at this, and seems to be what I look for. In a few days, when I have time, I will try it on some files and see the results.

[gentoo-user] USB permissions glitch
Something keeps resetting the permission for /mnt/usb to 755 , which prevents me accessing a USB storage stick as user. My user is in the USB group : 'usb:x:85:haldaemon,purslow'; in /etc/fstab I have : '/dev/sdb1 /mnt/usb auto noauto,user,umask=000 0 0' (I never use 1 USB device at a time, so this is ok). Till last week, it worked as expected there's been no change in Udev rules. I've made a work-around by amending the Bash alias I use to mount it to alias musb='mount /dev/sdb1 /mnt/usb ; chmod 777 /mnt/usb' , which does solve the problem, but is there a more conventional method ? -- ,, SUPPORT ___//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT`-O--O---' purslowatchassdotutorontodotca

Rodrigo Lazo [EMAIL PROTECTED] writes: [...] http://fluxbox.sourceforge.net/fbpager/ Yeah, I knew about that one and have tried it but its no more aware than bbpager (blackbox). By that I mean, clicking inside the pager does not transport you to that desktop. At least I did not see that happen here. However I've since found that in blackbox one can use the mouse scroll wheel to quickly navigate to any desktop and bbpager supplies the quick visual reference. So I think with a little usage, clicking in the pager will not be my first thought when needing to change desktops. One other missing ingredient though is that you cannot tell what the windows displayed inside the pager are. I'm used to seeing what they are ala kde. But again the mouse scroll is so quick, that may not matter much either. So far I can never remember which way to scroll. but with only 4 desktops I actually ever use... it still is very quick to mouse scroll until you find the right one.

Ignoring the MS/*nix argument for a moment. How does fragmentation work on hardware RAID?

[gentoo-user] ssmtp att woes
I recently switched to att from another isp. At that other isp, my ssmtp setup worked perfectly. With att, a similar ssmtp setup (modified appropriately to point to att's smtp server) does not work at all. ATT told me to use the server smtp.att.yahoo.com and port 465. So my ssmtp.conf file looks like: Debug=YES [EMAIL PROTECTED] mailhub=smtp.att.yahoo.com:465 AuthUser=xxx AuthPass=yyy rewriteDomain=att.net FromLineOverride=YES UseTLS=YES and my revaliases file looks like [EMAIL PROTECTED]:smtp.att.yahoo.com:465 The result of the command mail -v -s test [EMAIL PROTECTED] is: [-] 220 smtp122.sbc.mail.sp1.yahoo.com ESMTP [-] EHLO tobey [-] 250 8BITMIME [-] AUTH LOGIN [-] 334 VXNlcm5hbWU6 [-] am9obi5ibGlua2E= [-] 334 UGFzc3dvcmQ6 [-] 535 authorization failed (#5.7.0) send-mail: Authorization failed (535 authorization failed (#5.7.0)) Can't send mail: sendmail process failed with error code 1 I read somewhere that some people can't get att's port 465 to work with ssmtp and that they have used port 587 successfully. Not so for me. Using port 587 (replacing 465 by 587 in ssmtp.conf and revaliases), the result of mail -v -s test [EMAIL PROTECTED] is: SSL_connect: Success send-mail: Cannot open smtp.att.yahoo.com:587 Can't send mail: sendmail process failed with error code 1 I have no problem at all sending mail to my att.net account from various gmail accounts I use, so I know that my password and username combination functions. I can telnet to smtp.att.yahoo.com at either port 465 or 587 and get a response, so nothing is blocking either port. Any insights or suggestions? John Blinka

A Assuming a level that performs striping, it would be alleviated, yes, but even striping is at its fastest when performing sequential reads, it just reads sequentially from more than one disk at a time... but the fact that one disk will likely be reading while another performs a seek would probably reduce the impact of the seeks considerably.

As a side note, SSDs are the quickest way to remove all worries where fragmentation is concerned, having negligible seek times as they do... and physically smaller platters (2.5in SAS drives, the Velociraptor, etc) at least make a small dent on worst case seek times... reducing the impact that way. -- Poison [BLX] Joshua M.

[gentoo-user] Automounting of USB drives
I have finally reached the point where I use enough USB media (external hard drives and flash drives) that I would like to set up a system to automount the media devices for me. I have read in the past about hal + ivman and a bit of googling has brought up AutoFS as well. I was just wondering what the best system to automount USB media would be. I am looking for something that is relatively easy to set up and is also well maintained. Thanks in advance for any suggestions. AJ
