cannot transfer over 32KB file using UDP

[Joon]

Hi Guys.

I cannot transfer over 32KB file using UDP.
Is there anyone who can help on this?
What configuration should I change for this?

[Steven E. Protter]

UDP is pretty broad. How are you trying to do the transfer? What script or tools are involved?

More detail means faster solution.

Hi

Here is error message.
It is for transferring within internal communication.

-----------------------------------
sh: a.out: not found.
/home/crevol/src/test]./a.out
Send Buffer = (262144)
Recv Buffer = (262144)
strlen = (32770) <- file size
sendto() fail (ret = -1)
SndUnixSocket() fail (errno = 218)

--------------------------------------

if the size is below 32K ..It is successfull as below.

/home/crevol/src/test]./a.out
Send Buffer = (262144)
Recv Buffer = (262144)
strlen = (32700) <- file size
SendLen = (32700)
RecvLen = (32700)

---------------------------------------

I think Send/recv buffer will have a key for this problem.
Is there anyone who can help?
please let me know the solution

What patch levels are you maintaining on your server.

I would recommend the latest ARPA patches on the system.

Joon,
it is still not very clear what is it that you are using for the udp transfer. Are you nfs mounting using udp and then copying?
more info would be helpful to provide a good response
thanks
