Hi All,
I have this particular problem which I understand is possible in Linux using iptables.
I would like to know how to achieve this in HP-UX.
I have a HP-UX server with 2 NIC cards - lan0 and lan1 (both on same subnet)
This server keeps doing regular routine tasks and need to transfer files to different remote machines on frequent basis.
What I need is that all the file transfers (especially FTP or SFTP) should happen using lan1 rather than lan0 (which is default)
Your guidance will be really appreciated.
Thanks

Re: Force FTP on lan1 on specific interface
Is this APA?
Multiple NICs in same subnet may cause a lot of trouble... you should avoid this.
Hope this helps!

Torsten.

Re: Force FTP on lan1 on specific interface
Hi Torsten,
Even I heard that multiple NIC on same subnet might cause problems. Why is that ? Any specific reason ?
Next, at the moment we dont have APA. In this case Is it possible to achieve the requirements I mentioned ? How ?
Is it possible using APA ? How ?
Thanks

Re: Force FTP on lan1 on specific interface
Why do multiple NIC with same subnet create problem ?
Using APA, I will surely be able to bond multiple NICs together and all traffic will be common to this logical interface but my requirement is a dedicated NIC only for FTP connections.
Is this possible with/without additional S/W?
Thanks

Re: Force FTP on lan1 on specific interface
You will have problems if not using ip_strong_es_model.
Best description I can find for the moment
(maybe the best anyway):
http://www.mayoxide.com/presentations/Understanding_hpux_routing.pdf
Problem in very, very short:
application is sending data over NIC1 and waits for answer, but answer received to NIC0, so NIC1 will receive nothing.
See the related thread:
Hope this helps!
Regards
Torsten.

Re: Force FTP on lan1 on specific interface
One last query - If I assign different subnet (say X) to one of the NIC and place the other machine where the files should be copied on same subnet X, in that case both subnets can be configured on NIC cards of HP-UX and FTP will happen dedicatedly on seperate interface.
Correct ?
Thanks
