Cannot communicate with Linux (Redhat, Ubuntu, CentOS, Solaris, etc.)



  1. Please check the Compatibility and Interoperability Matrix and verify that the Operating System you are trying to protect is listed.
  2. The Unitrends Client Agent is installed at /usr/bp/. If missing packages (dependencies) are encountered, it must be resolved. In some cases, you may need to resolve 32-bit and 64-bit dependencies.
  3. A common mistake is to install the wrong package. For example, while Novel OES resides on SUSE based, the installer is NOT the same. There is a dedicated installer for Novel OES which includes the TSA security module, that is not included in the SUSE package. The Novel OES installed (oes_cnt) is all that is needed (as long as you have your dependencies).
  4. During the installation process, the option that a Firewall exists should have been chosen which sets the port to 1745 for data transfer. If this did not occur (or if a communication/permissions issue prevented it), the change may not have been implemented. Please check the /usr/bp/bpinit/master.ini file and ensure the data= port has been set to 1745. Save that file and restart the Unitrends agent (usually bpinetd <new *nix systems> but could be xinetd <older>). If you do not see it, you can issue this command from your SSH connection to create the entry for you: 
/usr/bp/bin/bputil -p “Configuration Options” data 1745 /usr/bp/bpinit/master.ini  
  1. Allowing communications between your *NIX server and the Unitrends system, can eliminate firewall issues right away. At the minimum, TCP ports 1743 (Unitrends to Client Agent control channel) and port 1745 (data transfer, as set in step 3 above) must be allowed bidirectional. If port 1745 is not an option on the *NIX computer, you can choose a port number between1745-1844.
  2. Once you have configured everything as needed, consider rebooting the Linux systems. Sometimes, an underlying Linux process is holding the completion of the install/setup. This is rare, but can occur.



A missed step in the configuration process or permissions issue prevented changes from being implemented.
