Chris, The LDM server uses port number 388, which is a well-known port (i.e., it's registered with IANA). On a Unix-like system, port numbers less than 1024 require root privileges in order to bind to them. One could build an LDM that used a different port number, but then every other LDM that wanted data from it would have to be told (in the LDM configuration-file) to use the non-standard port number. It's doable, but not recommended. > I am curious to see if there is a workaround to installing LDM without > root user access. I have my own account on an HPC but I don't have root > permissions. What are my options and what are the drawbacks (if any)?
