When I use ftp programs like filezilla and notepad++ I have problem to transferring files to my ftp-server. This problem exist only at my home. My theory is that my routers are making the problem and my question is how can you check if it is the router that causing the problem?
How can I fix it?
you can add a firewall rule that allows everything / turn off your router firewall, if it then works, you know its that, so before you turn it back on add the ftp ports in there.
It might also be windows firewall blocking the ftp program also.
check the firewall rules to see if standard ftp access is allowed. Alternately you can try an ssh client like winscp to make a secure connection and see if this goes through

I want to write a CLLE Program to transfer Files from the IFS to a Webserver.
The Webserver is registered in the Hosttable from the Iseries.
(commandline: CFGTCP -> Option 10 -> Scroll to the Webserver IP)
Current CLLE Program: (only the ftp-access)
PGM
OVRDBF FILE(INPUT) TOFILE(CMDDTAR7_2/US9FIP) OVRSCOPE(*JOB)
OVRDBF FILE(OUTPUT) TOFILE(CMDDTAR7_2/US9FOP) +
OVRSCOPE(*JOB)
FTP RMTSYS('10.1.2.99')
ENDPGM
After i call my Program i get some results in a PF-File.
The Results are in German but i translated shortly for you.
The Connection is unavalable to 10.1.2.99 on Port 21. Try it again later.
[...]
My Question at the end.
Do you have some solutions for me to transfer xml files to my Webserver from the iseries?
You're writing about a web server and you want to transfer files by ftp. Perhaps you're mixing up protocols here. I'll concentrate to resolve your apparent ftp connection problem.
Seems that the destination host 10.1.2.99 doesn't accept connections on Port 21.
Please make sure, there's no firewall or other stuff blocking your request to the destination host. Moreover, on the host 10.1.2.99 try telnet 10.1.2.99 ftp or ftp 10.1.2.99 in a command window, depending on OS and installed components.
Before automating, just test manually if you can successfully connect and log in via standard command line: ftp 10.1.2.99.
Transferring data by FTP is just fine in a local LAN. Beware that any data including username and password will be transferred in clear text and thus can be possibly read by others as the intended hosts.
Following up to your comment: Actually there are many possibilities to copy files. If you're running a recent version of IBM i, I'd opt for using scp. It's encrypted and thus safe for running outside of local LANs. Great to automate by utilizing Key-Authentication instead of passwords. And many web hosting companies offer scp/sftp access.
I am trying to run ftp client and server.
The connection successful only if both server and client windows firewall is turned off.
I tried to turn the firewall on and allow roll for:
1. (inbound and outbound) tcp port 20-21 allow
2. allow end point communication for server-client
However, my problem still not solved.
Anyone has any other ideas?
Thanks ahead
Fixed it. The server throw an exception. I found it when i created log file on both server and client side
I made a custom http server using java. It runs properly on XP machines and when I open connection to that server from a different machine using its IP address and port it used to work. But in windows 7 it is not working. When I see the firewall it shows several rules. It would be great if someone lets me know which rule I should enable to allow incoming connections.

I have been trying to find some way of redirecting outbound TCP packets under windows, but so far have not been successful. Does anyone know of any software/code bit that would do something like that?
I am not even sure it is possible with the windows stack.
I am looking at doing something similar to what "-j REDIRECT" is to iptables.
EDIT: to be more precise, what needs to be done here, is to transparently(ie without the original application having to do anything) redirect outgoing tcp packet with a certain destination port to a specific ip.(alternatively redirecting them to a local port would be fine too since I can then just use something like rinetd or any port forwarder)
Netsh is a command-line scripting utility that allows you to, either locally or remotely, display or modify the network configuration of a computer that is currently running.
netsh interface portproxy add v4tov4 listenaddress=localaddress listenport=localport connectaddress=destaddress connectport=destport
see BarbaTunnel here and use its port redirecting

Having a process called "foo.exe", is there a way to forward everything it communicates over TCP/IP to a forwarding proxy located elsewhere? This forwarding should not reflect to other processes.
Another question: if there are multiple network adapters, is it possible to force a process to use one specific adapter.
Since in this example the targethost.com is known, I could just edit "system32\drivers\etc\hosts" to map targethost.com's IP to localhost, where on port 8765 would be the first forwarder waiting for an incoming connection and pass everything forward to proxy.foo.com. I was wondering if there's a more elegant way of doing this.
This is not for malware, I'm doing some network testing with my complex home network. Thank you for warning us.
Some free software for this would be perfect, alternatively a code idea (native or .net). Thank you very much.
It's not too hard if you make your own computer a firewall, then your app connects to a port on your own computer, and that port is forwarded to both the original destination and logged or forwarded on to your spying computer.
Alternatively you can make your other computer the firwall and have it log/forward the info.
Finally you could use a sniffer.
SocksCap will probably do the job (if you're OK with establishing a SOCKS proxy at proxy.foo.com).
You could hook into the TCP stack, for example, by using the Windows Filtering Platform or its predecessors, or you could substitute the network libraries/calls of that particular process.
