Subject [jira] Commented: (NET-141) FTPClient/DefaultSocketFactory does not regard default timeout
Date Mon, 25 Sep 2006 15:17:51 GMT
    [ ] 
Daniel Savarese commented on NET-141:

This is not a bug.  You used the API exactly as intended.  If you want a connect timeout,
you need to create a socket factory (this has been explained multiple times on th mailing
list).  Commons Net 1.4.1 is JDK 1.3 compatible. Therefore, it cannot support connect timeouts.
setDefaultTimeout does exactly what it is supposed to do. It sets the socket timeout (read/write
timeout). For a release that supports JDK 1.4 or 1.5 as a baseline, connect timeouts will
be added.

there will be no exception after 1000 ms. The exception will be thrown after a default timeout
of three minutes. (Three minutes on a debian/ and a suse machines. Might be different on other

> Digging through the code I found, that DefaultSocketFactory which is used be SocketClient
does not care about any value set with this method. It creates a new Socket with Socket(hostname,
port) and relies on the VMs behaviour.
> To get this fixed I set a custom SocketFactory with client.setSocketFactory(socketFactory);
that uses a timeout for socket connection.
