Configuring EDI Communication

EDI is a complex application involving data communication, text file manipulation and archival, document translation, and database mapping. This document will describe configuring a Linux machine to exchange data with an ftp server on the web for EDI.

Configure File Access

Starting with version 3.0, Zentyal uses Samba 4.0 to provide ACL-based file access permissions for MS-Windows clients. EDI file exchange is handled by a Linux process in the server and not a Windows client, which introduces file access issues.

First, access privileges must be set correctly on the file shares. To verify this, login to Zentyal administration in a browser. On the left menu, select OFFICE ‣ File Sharing. Check the boxes for Apply ACLs Recursively as shown here:


Save changes after this step.

Next change access privileges for the WARES group:


Again, save changes after this step. If file access is confused here, it may be necessary to remove the WARES Access Control and save changes, then re-add the corrected Access Control. From a Windows station, test file access by running the WARES program.


In Zentyal prior to 3.0, use the following console commands to set access permissions on the WARES share:

sudo chgrp -R __USERS__ /home/samba/shares/arev
sudo chmod -R g+s /home/samba/shares/arev

Configure Server FTP

The Linux server must have a competent ftp client. Open a console session on the server, and install lftp with the command:

sudo apt-get install lftp

The lftp program will run in non-interactive mode, taking its commands from a script file. The script file should be saved as /etc/waresedi.conf, with owner root:root and permissions 600. The text of a sample file follows:

set dns:order "inet inet6"
lcd /home/samba/shares/wares/connect
open -u {uname},{passwd} {hostserverURL}
mput -c -E ./snd/* -O ./{OUTBOX}
mget -c -E ./{INBOX}/* -O ./rcv

Schedule Exchange in Webmin

For convenience, remap data shares for the root user. Open a console session on the server, and type the following commands:

sudo ln -s /home/samba/shares/shared /S
sudo ln -s /home/samba/shares/wares /W

Next use the browser to login to Webmin at https://officeserver:1000. From the left menu, select System ‣ Schedule cron jobs, and make a job with the following command:

date >> /var/log/cron.log; lftp -f /etc/waresedi.conf 1>> /var/log/cron.log 2>> /var/log/cron.log

For access to work in Zentyal 3.0 and above, add the following at the end of the command:

; chgrp -R wares /W/connect/rcv ; getfacl --access /W | setfacl -M- /W/connect/rcv/*

Schedule the job to run every 15 minutes between 7 am and 7 pm. Test run the job, and check the output with the command:

cat /var/log/cron.log

Finally, manage the log file: System –> Log File Rotation –> Add a new log file to rotate. Accept the default management options for the new log.
