According to CERT.org: The worm requires a user to execute the malicious attachment either manually or by using an email client that will open the attachment automatically. Upon successful execution, the worm installs itself as C:\%windir%\winppr.exe and also creates the file C:\%windir%\winstt32.dat. An entry is also added to the Run registry key so that this executable will be run upon system restart. The key installed in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run is ScanX with the value c:\winnt\winppr.exe /sinc. The program then proceeds to scan files with certain extensions (htm, html, dbx, hlp, mht, txt, wab) on the compromised system for valid email addresses, and it uses an internal SMTP engine to email itself to those addresses. Linux does not have any of the necessary structures described above (e.g. a registry). OTOH Linux boxes could be adversely affected by a flood of mail being generated by infected Windows client boxes. However, there is a pseudo registry in Wine implementations. I checked the wine registry files in my Redhat 8.0 and the registry key that the worm looks for (according to CERT) is not present. That is not to say that the virus couldn't be modified to attack a wine-based Linux system, but then there is the additional hurdle of permission to modify root-controlled files. -- burns ___ Linux-users mailing list [EMAIL PROTECTED] Unsubscribe/Suspend/Etc - http://www.linux-sxs.org/mailman/listinfo/linux-users

The wine registry files aren't root controlled, they're in the user's .wine directory. And the virus adds its own entries in the registry using the Win32 API calls. But the autorun entry might be of no effect as Wine probably does not notice it. But it's important to realize the goal of Wine is to give a Windows app - whether malicious or beneficial - a near perfect simulated Windows environment to run in. So as Wine gets better, so does its ability to expose us to such malware. Since, IIRC, Outlook, Outlook Express, and Internet Explorer are reported to run near perfectly in Wine (or Crossover Office), it would be prudent to assume a virus would have access to all the right facilities to run as normal. But I'm speculating alot. It does, however, severely call into question our never ending efforts to be able to run Windows apps on Linux (VMWare, Win4Lin, Wine).

When they used FAT32, the disk transfer is much slower than EXT2/3. But this tool may make it possible to resolve that. Also, lots of small files waste disk space on FATxx. Thanks!

What I would like is reccomendations for a win backup program that can be automated and made to save to a particular destination. To write a back up of the windows computer to the ext2, or to read a backup from a Linux system on a windows box? When we do a backup of the linux stuff, we have a script that makes a ZIP file, naming the file with the current date and time (and placing a file in the backup with that same name). Then, on the windows box, just unpack the zips in order of file name. To make similar backups on windows, I would install cygwin (painless through a windows installer) and use basically the same script. I have not done this. Our script relies on the find command and a timestamp. I do not know how the file access times works on FAT16/32 (it is the file system more than the OS that limits this). If you are interested, I could send you the script I use. It is nothing fancy, but does lots of error detection to not be fooled by an incomplete backup. I have not seen any commercial software that is as lean as I would like that runs on both OSs to deal with backups in both directions.
