FTP Socket Error

s0110655

Hello,

When I try to run the sample code of the Alfresco tutorial, I receive an ftp error:

10:08:42,500 ERROR [alfresco.ftp.protocol] FTP Socket error
java.net.BindException: Address already in use: JVM_Bind
   at java.net.PlainSocketImpl.socketBind(Native Method)
   at java.net.PlainSocketImpl.bind(Unknown Source)
   at java.net.ServerSocket.bind(Unknown Source)
   at java.net.ServerSocket.<init>(Unknown Source)
   at java.net.ServerSocket.<init>(Unknown Source)
   at org.alfresco.filesys.ftp.FTPNetworkServer.run(FTPNetworkServer.java:377)
   at java.lang.Thread.run(Unknown Source)

Any ideas?

This means another application on the same machine is already using port 21 - the FTP server port. Are you running another FTP server or maybe IIS?

Thanks,

Hi,

I had a Apache HTTP server running, but I don't need it any more so I have removed it now. I have 2 Tomcat application servers running: one 5.5.9 where I already deployed another application on before I started using Alfresco. I had some difficulties for deploying Alfresco on an already installed Tomcat, so I followed the default steps from the tutorial (assumption that no mySQL DB or tomcat was installed yet). The original Tomcat 5.5.9 must be started manually and is not running when I run my code. I also executed netstat -a to see which ports are used. It seems that the ftp port is not yet taken by any proces:

When I run alf_start.bat and again execute netstat -a, I see that the ftp port is added to the list…

What do you think?

Hi,

Could you email your alfresco.log file so I can see if there is some other error that may be causing the problem.

Thanks

Hi,

How are you stopping/starting Alfresco/Tomcat ?, are you redeploying the Alfresco war file ?.

Cheers

Gary

Hi,

I run the alf_start.bat file to start Alfresco and the alf_stop.bat file to stop Alfresco. The only thing that alf_start.bat does is calling the alfresco.bat file whos content is printed below:

@echo off
rem —————————————————————————
rem Start script for the Alfresco Server
rem —————————————————————————

set CATALINA_HOME=C:\alfresco\tomcat

rem Set any default JVM options
set JAVA_OPTS=-Xms128m -Xmx512m -Xss64k -server

rem — If SetPaths.bat already exists - assume set by hand and use as is
if not exist "SetPaths.bat" goto getpaths
call SetPaths.bat
goto start

:getpaths
call RegPaths.exe
call SetPaths.bat
del SetPaths.bat

:start
set PATH=%JAVA_HOME%/bin:%PATH%
rem —————————————
rem Start Components
rem —————————————

if not ""%1"" == ""start"" goto nostart

rem —————————————
rem Start Tomcat
rem —————————————

echo Starting Tomcat…
call "%CATALINA_HOME%\bin\startup.bat"

rem —————————————
rem Start OpenOffice for transformations
rem —————————————
if exist "start_oo.bat" call "start_oo.bat"

goto nostop
:nostart

rem —————————————
rem Stop Components
rem —————————————

if not ""%1"" == ""stop"" goto nostop

echo Shutting down Tomcat…
call %CATALINA_HOME%\bin\shutdown.bat

rem —————————————
rem Stop OpenOffice for transformations
rem —————————————
if exist "start_oo.bat" c:\windows\system32\taskkill /f /im soffice.bin

:nostop

I hope this can help you.

Thanks!

Hi Steven,

After you stop Alfresco/Tomcat can you run a netstat -an and check if the FTP server port is still in use. If it is still in use can you check if there is a Tomcat process still running (the image name will be java.exe in the process list).

You could also try changing the FTP server port in the classes/alfresco/file-servers.xml file, add <port>1021</port> to the "FTP Server" configuration section. That would help to rule out that it's not another application that's using the port if the JVM_Bind error still occurs.

Cheers

Gary

Hi,

I changed the port number in the xml file like you suggested and it works now.

Thank you!
