General :: [Redhat 5.5] Unable To Access Network From An Oracle-started Process?

We have a Oracle 11.2 database running on Red Hat 5.5. The database have a scheduled job to fetch some files from another server using ftp, and herein lies the problem.he job runs a pl/sql that runs the function in an (by us compiled) external libraryThe ftp-functionality itself is done by using libncftp and it's API's.The process starts correctly, but then trying to login to the actual ftp host, ncftp only reports "Unknown username/password" (which is not the case).I have the exact same code in an executable and when run from an interactive shell, it works fine.So the only thing I can come up with, is there are differences when the process is started by Oracle, rather then being ordinary" process.And I am stuck.If there are any environment variables, paths etc missing when running the extproc-process, how do I find out which?Because the real problem is NOT wrong user or password.
