bestcrypt permissions issues

[afabco]

I'm trying to use bestcrypt again. It appeared to emerge ok, but when I tried to use it, I got the following error:

bash-2.05b$ bcmount lswap win
This program must be run as root or have the SUID attribute set
bash-2.05b$ bctool
This program must be run as root or have the SUID attribute set

lswap is an old bcrypt container.

So I went ahead and SUID'ed it, but is that right? Or is it an indicator of something wrong. Is that something that the emerge should have done? I am normally very leery of SUIDing or SGIDing stuff.

bash-2.05b$ su

leeamlp thomson # which bctool
/usr/bin/bctool
leeamlp thomson # ls -la /usr/bin/bc*

leeamlp thomson # chmod u+s /usr/bin/bctool
leeamlp thomson # exit
exit

Anyway, it worked, but then another problem came up.


bash-2.05b$ rm lswap
bash-2.05b$ bctool new -a rijndael -s 750M lswap
open("/dev/bcrypt0", O_RDONLY): Permission denied

I'm using udev. Is this a udev thing? How do I fix it? Do I fix it? Is it something that the emerge should have done, or is it something I need to do?

Thanks!
