I started having this problem after upgrading to the new kernel, pl12. One of my terminals, when firing up getty, will "spaz" getty via init with this error. Occasionally, it will work, but most of the time it simply bugs out. I'm using the latest libraries (4.4.1) and gcc (4.5.x?). Suggestions? -- Jawaid Bazyar | Like UNIX? Like your Apple IIGS?

I'm looking for one which supports Internet mail and news. The only one to do this is 'mbox' - but alas, it is all in German.

Yes, but due to the way in which unix passwords are encrypted, each password uses an encryption key (called a "salt"), which is stored as the first two characters of the encrypted password. When you are attempting to crack a list of passwords, you must actually re-encrypt your test word for _each_ of the salts used in the password, and as there are (I think) 4096 different possible salts, chances are that you will have to re-encrypt your test password for each of the encrypted passwords in the list, and thus it is no quicker to attempt for a list of passwords, than for each password individually. : So, there are two possibilities.

I'm guessing here but it sounds like it's not because those programs are suid but because they have permissions like -rwx--x--x as would be typical for an SLS installation. In spite of the fact that I think this kind of security paranoia is ludicrous, I have already modified the next version of the nfs-server so that execute-only programs do work correctly over NFS. For the time being, you may revive your system as follows: # find / -type f -perm +0001 -print | xargs chmod +r This makes all world-executable files also readable, as they should be. Or if you are in a more cautious mood try: # chmod +r /bin/* /usr/bin/* Then again, you are free to pick and choose. -- Suffice it to mention that irreversibility, as related to the direction of time, is by no means in contradiction with the laws of dynamics; on the contrary, it follows from these laws whenever a suffcient degree of complexity is reached. - I.

This "salt" value is coded in the first two characters of your (encrypted) password.
