Port no. problem

is there any problem if my server is running on port 8080 instead of 8081.
since i tried changing the port by including the ‘listen_port’ variable, but on running the server, it displays ‘unrecognised variable’.

Unrecognized variable means one or more of the variables are not supported by the vsftpd server, please understand as to which variable is wrong.
There might be a spelling mistake somewhere.

i have copied the variable from the forum as listen_port wasnt there in my vsftpd_v1.conf file

for_forum

Check for additional spaces, remove them.

thanx for the help @Rahul-Crio.do sir!
