I've had the same problem. It seems that Linux doesn't treat certain
salts the same way as other operating systems do. For instance, here
are the results of crypting "foobar" under two salts under Linux and
Ultrix:
Salt Linux Ultrix
fp fpyAfoAVGBL3M fpyAfoAVGBL3M
t% t%/WY11rJpVX2 t%ayFkX053rKc
If you have a crypted password resource in your .Xresources, try
re-encrypting it using a salt which is only letters. I did the above
encryptions using perl:
perl -e 'print crypt("foobar", "fp"), "\n";'
I don't have time to track down the underlying Linux C library
problems and report them to the appropriate people right now,
unfortunately.
