Both are running Ubuntu 8.04, one is a core 2 duo, the second is a dual quad core (grin!!). I used the make target of linux-x86-64. Unfortunately when I try to run the following, I get a segmentation fault. john -format:netlm -config:/tmp/john.conf.9143 -external:HalfLM -incremental:LM -session:/tmp/john.session.9143 /tmp/john.passwd.9143 I have built a debug version and loaded it up into gdb and here is the backtrace output. (gdb) backtrace #0 0x00007fca3ecf8d9d in ??

Any help would be much appreciated. Download attachment "signature.asc" of type "application/pgp-signature" (253 bytes)
