Using different network for FTP transfer

Srinikalyan — Mon, 25 Jan 2010 07:43:30 GMT

Hi,
Can I use the different network i.e. not using the public network for the FTP to transfer? Say we have two LAN's one is public and other one is the private dedicated high gibabit network only available between source and target server. Is it possible to use the private network to transfer to the target server through FTP?

Thanks,
Srini

Hello,

Can you please explain what do you really want to do? It is not very clear.

I understand that you have two Local Area Networks, one you call it "Public" and another you call it "Private".

On the last one you only have 2 computers connectd. One of those runs a FTP server.

I believe this is not a problem to actually reach the FTP server from the other computer connected to this LAN.

Which computer have physical acces to the "Public" network?

If the two systems have routes to each other
over "the private network", and nothing else
(firewalls, et c.) interferes, then FTP
doesn't care.

With exactly no actual information on these
networks, it's not easy to say how you might
direct the traffic to use one or the other.

Steven in right about this.

If the computer which actually runs the FTP server have a direct connection to the public network, there should be no problems accessing from any other computer from this network or any other computer interconnected to this network, if the firewall rules would actually permit FTP connections.

Ok. Our need is to send 1TB of files from production server to the DR server for building the initial database standy build. We have dedicated DWDM link (2gbps) between these two Servers for the dataguard replication traffic. We have dedicated IP's and routing information as well for this particular traffic along with the default public interfaces details (physical node interface).

Public interface details:
INTERFACE_NAME[0]="lan3"
IP_ADDRESS[0]="10.27.128.11" #node IP
SUBNET_MASK[0]="0xffffffc0"
BROADCAST_ADDRESS[0]=""
INTERFACE_STATE[0]=""
DHCP_ENABLE[0]=0
INTERFACE_MODULES[0]=""

ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="10.27.128.4"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""

DWDM network :
IP_ADDRESS[4]=10.27.86.211
SUBNET_MASK[4]=255.255.255.240
INTERFACE_NAME[4]=lan4
BROADCAST_ADDRESS[4]=10.27.86.239
INTERFACE_STATE[4]=up

ROUTE_DESTINATION[1]="net 10.186.46.86"
ROUTE_MASK[1]="255.255.255.240"
ROUTE_GATEWAY[1]="10.27.86.227"
ROUTE_COUNT[1]="1"
ROUTE_ARGS[1]=""

With the above set of information, How can I use the DWDM network for the FTP traffic?

Thanks,
Srini

Sorry. I got it. I can use the dedicated network IP for the FTP to connect to the target server since we have the route between the two servers.

Thanks,

So the case is solved, right? Or better put it, there is no case at all.

Thanks. I got the answer hence closing the thread.

DR - implies distance to me. You may need/want to mess with -B options to both the ftpd and ftp client to get a sufficiently large socket buffer size to get a good throughput between the two systems.
