Usefulness of offloading cryptographic hashing of passwords

2013-08-09 Thread Nathan Goings
I recently read an article from facebook on password cracking. It got me thinking about how useful dedicated hardware might be for hashing passwords. Source: http://arstechnica.com/security/2013/05/how-crackers-make-minced-meat-out-of-your-passwords/ Fairly basic stuff (MD5, brute

How to select NAT port variations.

2013-08-06 Thread Nathan Goings
I'm dealing with old software that uses old NAT traversal techniques. I specifically need to select the NAT variation as defined by RFC 3489 (section 5). Generally I've used nat-to's 'static-port' option and gotten around this issue. After adding some clients host-side, it seems like NAT

Handling nested partition mounts with NFS (/usr/src)

I just setup NFS, and have gotten it working with my Windows 7 machine. Basically, I'm working on a driver and want to use a graphical IDE. /etc/exports: # /usr -maproot=root -alldirs -network=192.168.37 -mask=255.255.255.0 /usr/src -maproot=root -alldirs -network=192.168.37
