Problem

amcheck(8) and other programs give the error:

Port nnn is not secure

Solution

Because `amcheck', as some other Amanda programs, must be installed as setuid-root. Run `make install' as `root', or `chown' all Amanda setuid programs to `root', then `chmod u+s' them again, if `chown' drops the setuid bit.

Solution

When the Amanda server contacts a client, it requests one or more ports on the client for communication. Ordinarily, the client will respond with clients in the "secure" range (0 - 1023). If the client's configuration is different, or if it cannot allocate such a port (because it is not running as root), then this error will appear.
