Re: HP SSL & SO_KEEPALIVE + TCPWare-TCP

If you change the qio to set keepalive to do it on the listen channel and do it after the listen and before the accept, then it will work.

I will accept the argument that it should work your way too.

Setting the keepalive on the listen channel is more efficient as you do one call for many accepts, instead of one call for each accept.

Hi Richard,

[Setting the keepalive on the listen channel is more efficient as you do one call for many accepts, instead of one call for each accept.]

Are we talking about the BG driver here?

If so, is this "anomally" going to be fixed?

Nice question!

Yes, I will be investigating why it the keepalive timer isn't started when keepalive is enabled for an existing connection and if it can be changed so that it works as expected.

Re: HP SSL & SO_KEEPALIVE + TCPWare-TCP

Sounds good!

In the meantime if anyone can report back on whether it is just the KEEPALIVE option that is exhibiting this recalcitrance (or whether it extends to Full_duplex_close, Linger, InLine, TCP Options, and so on. . .) it would be much appreciated.
