usesolkeepalive breaks sol session

Hi,

I noticed that since commit 21fbd0e9678dbe3c4497b0c554922ccf9c84fc3a using usesolkeepalive option for sol activate is causing broken connections to IPMI on Dell IDrac 8. It seems that send_sol function when using usesolkeepalive is always returning NULL, hence ipmi_sol_keepalive_using_sol returns -1. After commenting out return -1 statement sol session works correctly. I'm not sure if it's BMC or ipmitool bug (this work correctly on our Lenovo nodes).

To be more specific, when nothing is going on both sides (no new text is send to/from server) session breaks after 90seconds with message Error: No response to keepalive - Terminating session even, when connection is active on BMC side.

Hello,

I'm not sure if it's BMC or ipmitool bug (this work correctly on our Lenovo nodes).

does it mean it works with servers from another vendor(Lenovo)? In such case, I would assume it's a BMC bug.

To be more specific, when nothing is going on both sides (no new text is send to/from server)

But there should be something going on on TCP/IP level. I can only suggest/ask to use % tcpdump; to check if it's true. Also, another thing is to get in touch with Dell. They have access to DRAC, I don't. Sorry :| Unfortunately, help from other people which work for other vendors is unlikely, although you can still try to ask at IPMI tool devel mailing list. Not that many, if any, people follow issues at SF.net.

Best regards, Z.
