I'd like to connect (ftp) to the Internet through a firewall from HP-UX 11.0.
Windows PC's in the same environment can use the Winsock Proxy Client and get through just fine.
What questions do I need to ask of my network support staff? Is there a stock HP-UX solution to this issue? Will I need to look at ncftp or some other item?
Thanks in advance.
Solved! Go to Solution.

Re: HP-UX ftp vs. Microsoft Winsock Proxy Client
FTP makes use of ftp-control (TCP port 21) and ftp-data (TCP port 20), thus the firewall must open up at least these two ports for outbound connectivity to the Internet from your HP-UX client.
If you are using Checkpoint FW-1 for your firewall, it will be possible for stateful inspection of your FTP packets such that the firewall automatically detects the high-numbered port that it needs to open up for the reverse ftp-data connection that is initiated from the FTP server.
If not, then you may have to open up a whole range of high-ports to ensure that your FTP transfers work.
Symptoms of ftp-data being blocked but ftp-control works through the firewall is when you can get connected to the FTP server from your client, you can login using the correct userid and password but when you perform an ls, it hangs.
When that happens, revisit your firewall rules and also check your firewall logs for dropped packets between the client and server.
Hope this helps. Regards.

Re: HP-UX ftp vs. Microsoft Winsock Proxy Client
As Steve said, in checkpoint there is at least one way (and I know a few more) to give your HP-UX system access.
If your running MS Proxy (which is what the winsock client is for) then you will have problems unless you make changes to the MS Proxy server to allow normal auth instead of NTLM only auth (default). Then you will have to use a browser because there are no good GUI ftp clients I have found for HP-UX which support an auth-proxy. If the Proxy is running No-auth, then just use whatever client supports proxy.
You will only need ports 20 and 21 for FTP.
Regards,
Shannon

Re: HP-UX ftp vs. Microsoft Winsock Proxy Client
i use a "socksified" ftp client on my system. there should be some freely distributed socks bits for HP-UX out there on the net somewhere. you then need a socks server that can get through the firewall - perhaps the firewall itself supports socks.

Solutionyou can get "socks" for HP-UX from the HP-UX Porting Archives:
http://hpux.asknet.de/hppd/hpux/Networking/Admin/socks_cstc-4.2.pre1/
Then you can configure and use your HP-UX box just like those PCs...
