I have a backup script that mounts a drive on my xp workstations. Is
there a way I can set this script to run as root so that I do not have
to su every time I want to run it?

Dirty way: If you are using NFS and are _not_ using an auto mounter of some kind (amd, autofs), change the ownership of the script file to root, then setUID on it. like this: chown root SCRIPT chmod +s SCRIPT Note: Using SUID is not particularly secure. It's usually ok in a trusted environment, but if a hacker could get anywhere near your linux machine DON'T DO IT THIS WAY. In that case, look at using amd or autofs. Cleaner way: Presumably you are using SAMBA to mount the drive from your XP box. In which case, you don't need to be root, provided that the mount point is owned by the user. For example, as user paulk, you could create a directory to use for the mount (mkdir ~/windows) and then you should be able to mount the samba share as the user with: smbmnt //machine/sharename ~/windows -o username=XPUSER,password=XPPASS and later on unmount it with: smbumount ~/windows However, for this to work, smbmnt and smbumount must be suid. Assuming you have a standard setup, you can do that like this (as root): chmod +s /usr/bin/smbmnt /usr/bin/smbumount Note: This is fairly safe to do; smbmnt and smbumount are designed to be run this way.

None of the files are in use. Nor are they system files of any kind. I know for a fact that the xp system is not using them. Any ideas as to what may be causing this? I am smbmounting the drive rather then using smbtar due to the limitations of smbtar. My script tars up a folder and the dumps the output to a text file. The script does this for about 4 different folders. It then tars the tarballs together into one file with the "index" text files also tarred up. It is then compresses using bzip2. The work files are deleted.

The only idea this description suggests to me is that the file in question was recently changed and buffered on the XP system, and the "change" tar detects is the result of the XP system sync'ing (or its Windows equivalent) the hard drive to the buffer. But this is fishing in a cloudy pond. Could you repost with a small snippet that reports the actual message tar (or smbd or mountd or whatever is giving you the error) posts for each of the two errors? -- -------------------------------------------"Never tell me the odds!"-------- Ray Olszewski -- Han Solo Palo Alto, California, USA ray@comarre.com ------------------------------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs ^ permalink raw reply [flat|nested] 9+ messages in thread

AFAIK yes, and the saying is, never run a script as root, root is evil, one small oversight and damage can be done period. I once was accused of destorying someones system because i said, "if" you want to get all the information from the script then you will need to run it as root, if it is run under a user it will not gain some vital information from your /etc dir, a few days later a mail appierd on that particular mailing list saying i had destroyed his system with my script. Many still use that script actually but thats asside the point, root is evil. > -jdr- > > Ray Olszewski wrote: > > Yes. You want to set the suid bit on it and have it owned by root.
