Distributed John

Hello, i have a problem in the execution of the client.
To begin, my config:
Ubuntu 8.04 Hardy
I install 'john' with 'apt-get install john' > version 1.6
I compil the last john with the mpi support: > version 1.7.2_bp17_mpi
I compil 'djohn-0.9.8.1'.
The two version of John work.


I run the server like this: "./djohnd -v -b 127.0.0.1 -c a-z -f a -l zzzz -d ."

I run the client like this: "./djohn -v -j /usr/src/john-1.7.2-bp17-mpi8/run -d . 127.0.0.1"

And i have this message:
"
getting charset from server...
getting external mode source code from server...
127.0.0.1 FIRST_WORD ariw bgdl
Unknown external mode: dJohn
[0] Terminating on error.
an error occured running john (exit code 1)
An error occurred during cracking, exiting...
"

So, where is the problem?


Thank you for your help.
