Users can create a network ODB connector to access an output database on a remote computer (see “Accessing an output database on a remote computer,” Section 9.3 of the Abaqus/CAE User's Manual). Abaqus/CAE or Abaqus/Viewer can start the server on the remote system and assign port numbers if the following are true:
The user name on the remote host is the same as the user name on the local system.
The remote shell command (rsh) or the secure shell command (ssh) is configured so that it does not prompt the user for a password.
Abaqus checks the security of the connection by passing a key back and forth between the server and the client. For information about how the key is generated, see the Dassault Systèmes DSX.ECO Knowledge Base at www.3ds.com/support/knowledge-base or the SIMULIA Online Support System, which is accessible through the My Support page at www.simulia.com. If a file called .abaqus_net_passwd is present in the user's home directory on the remote system, Abaqus uses the password in the file for authentication instead of the key generated by Abaqus. Abaqus checks that the user is the only account with permission to read and write to the password file. In addition, the user must update the file after 30 days, and the password must be at least eight characters long. These files are described in “Network output database file connector,” Section 3.2.20 of the Abaqus Analysis User's Manual.
If users experience problems establishing communication or if the user names are different, they can start the network ODB server manually from the command line using the abaqus networkDBConnector execution procedure on the remote computer. Abaqus uses the password in .abaqus_net_passwd to authenticate the connection between the client and the server if the user starts the network ODB server manually. If .abaqus_net_passwd does not exist in the user's directory on the remote system, the user cannot start the network ODB server from the command line.
You can disable network odb connectors by removing dmbwtr and dmbwtrd from the abaqus_dir/release/External/dmbwtr directory, where abaqus_dir is the Abaqus parent directory, and release is the release of Abaqus you are using.
