Solving Problems with the Embedded Performance Component
Running the Embedded Performance Component
under an Alternative User
Problem
If you run the embedded performance component process coda on
HTTPS-based managed nodes under a user other than root and coda is
configured to use the default port 381, coda will not start.
Description
The well-known ports from 0 through 1023 on most systems can only be
used by system (or root) processes or by programs executed by privileged
users. If coda does not run under root, it is not allowed to access
port 381.
Solution
The solution to this problem depends on whether you need a fixed port
for coda or whether you can run coda without a specified port number:
❏ With fixed port
Configure coda to use a port number higher than 1024, for example
port 50381:
ovconfchg -ns coda.comm -set SERVER_PORT 50381
❏ Without fixed port
Let the operating system automatically assign the next available
port number to coda:
ovconfchg -ns coda.comm -set SERVER_PORT 0
