FTP Server
 

I have a Fedora 11 box that serves as a FTP server that I have inherited, my problem is that I can’t find what process/program or daemon that’s hosting the FTP service or where it is configured

It doesn’t seem to be running any of the standard FTP servers the only ftp reference I have is a process that runs in the kernel called “nf_conntrack_ftp”

How can I find what application is hosting my FTP service?


Thanks

if your ftp service is LISTENING TCP Port 21 (by default), i guess you can try this command:

#by root
lsof -nPi |grep 21

netstat -plnt will hsow what process is listening on what port.

Java Tomcat
 

|Thanks Guys

it seems that Java is hosting the FTP server
tcp 0 0 :::8021 :::* LISTEN 1622/java


I know that the server is hosting java/Tomcat now just need to know where the configuration files are?

Hi,

It typically won't be a configuration file that you need to change - you'll find that the java application deployed on Tomcat has an FTP server embedded into it (using one of the Java FTP API's available) - thus you'll need to consider if you want to leave the application running or not? Or reverse engineer the application (if you have the source code).

Ok thanks that's a great help,

I do have the source code and can now comfirm that the FTP server is running as part of the Java application. Ok so I am getting near to what my real problem is, the FTP service does not seem to be working in both active and passive modes after a reboot. it seems to reverts to using passive mode only wich is a problem for users using windows FTP command line for batch processing.

I know its probably a long shot but does anyone have any ideas? I think it may have something to do with running a kernal process.

thanks

is there any possibility of runnng scp on that server ?

Well he's running some form of java based integrated FTP service, why would a standalone SSHD instance be an acceptable replacement? it's not compatible with FTP at all.

More than likely you'll have to modify the code. Its been a while since I coded up FTP in Java; from what I can remember; depending on the API you're using; there's a parameter for setting Active/Passive FTP.

I suggest you do is Google something like "FTP Commons Java Mode" - alternately you could post the source here and I can try to help if I can.

my point was not to use the deprecated ftp service but instead use scp which is easier to implement as well as encrypted.

just a suggestion.
