email problem

by Bill Mills-Curran

I'm having a problem with email bouncing to verizon.net addresses, and I suspect some other servers may be deleting it entirely. My config... I'm using mutt, which delivers to a local smtp server. My machine has a fake domain name (mills.curran), since I'm on a NAT'ed firewall. I route/relay my email through a web services provider with my own domain name (mills-curran.net) on a static IP. I know the issue is not a blacklisting, because the email gets delivered if I use the web interface for email at the mills-curran.net site. I suspect that verizon.net doesn't like the fact that the email header includes records including the fake mills.curran domain. I've tried some sendmail configuration changes with no success. Any suggestions? Thanks, Bill

The command I used was: "sudo dd if=/dev/hda of=/dev/hdb bs=512 conv=noerror,sync" This worked perfectly. I now have a duplicate NTFS drive that I can mount from KNOPPIX and Linux. I can also run Win2k from when I need to (not very often). Thanks to Chuck A. and Jamie G. for their help. -- -Chuck

reiserfs corruption....

by Eric Stein

Hi all, After a nasty power problem, I have corruption on a reiserfs volume. What I did: http://toba.ath.cx:724/~eastein/reiserfsck.txt I think I may have a damaged drive. The scariest prospect: Bad root block 0. (--rebuild-tree did not complete) Any ideas? Eric

Hi Chuck, I don't know what the default block size is for dd, but maybe you could try adding "bs=512" to the dd arguments, so that you're copying on sector boundaries. I can't explain why this would help (if it does), its just a hunch. :) Also, maybe you could you turn off DMA to one or both drives before doing the dd. "hdparm -d0 ..." or something like that. -Jamie
