FTP 501 Server Cannot Accept Argument

Scenario:

Normally we perform an FTP MGET with our trading partner to receive inbound x12 850s. Recently the networking group changed something on the firewall to cause an error each time we attempt to make a connection.

Each of the EBI FTP Adapters are set-up for ACTIVE connections.

Issue:

When we attempt to perform an MGET we consistently receive an error, regardless of the FTP trading partner.

EXTOL error message:


Depending on the trading partner, we were receiving a different error but they were all inter-related.

Command: PORT 192,168,1,129,102,151
Response: 501 Server cannot accept argument.
Error: Failed to retrieve directory listing

Resolution:

After continuous testing and conversing with the network group, we were still experiencing the FTP errors. After updating the FTP Adapters to PASSIVE mode, the FTP transaction errors went away.
