Hi There,

ftp was on port 21 and 20.



Moved to port 10121 and 10120 by changing in /etc/services and stopping and restarting inetd.



ftp-data 10120/tcp # File Transfer Protocol (Data)

ftp 10121/tcp # File Transfer Protocol (Control)



Application configured to run as follows:



Application services file:



FTPdata,S,gwsae02,dataftp,

FTPctrl,S,gwsae02,ctrlftp,



Resolves to the below in /etc/services:



ctrlftp 21/tcp # new ftp facility - open with port no.

dataftp 20/tcp # new ftp facility



start application:



entftps -c FTPctrl -e stnetr -s Parser -p FTPdata -d 10 -g m -by > logfiles/logftp 2>&1



APP DEBUG OUTPUT

and



gwsae02:editest:/users2/editest $ lsof -i tcp:21

gwsae02:editest:/users2/editest $

This is a vary tricky system to reboot, so if there is any way of identify and releasing the lock on the socket, the would be great.

Hi Mogamat,

Is your tcp_mgr running as "root"? Port numbers lower than 1024 are privileged ports. These ports can only opend by root-processes.
