Increasing Socket Handshake Timeout

Glenn Vassallo

I am sometimes getting a -462 error when attempting to connect to a secure socket.

retVal = sl_Connect(iSSLSockID, ( SlSockAddr_t *)&Addr, iAddrSize); // this sometimes returns -462

// From the sockets.h file, -462 means handshake timed out

#define SL_ESECHANDSHAKETIMEDOUT              (-462)  /* connection timed out due to handshake time */

As the error clearly reports that the handshake is timing out. Is there anyway to increase the handshake timeout as I could not find it defined anywhere?

Hi Glenn,

As of today, there is no option to increase\configure the SSL timeout.

Thanks,
Alon

Thanks Alon,

Please add this to your design change request/feature request database....if this is an option that the RFC allows to be configured.

Thanks,
Glenn.

Hi Alon

I also see this timeout errors and would vote for a better solution.

All,

We are checking options to increase the SSL time out in the next service pack.
At this point the advice is to start the SSL connection again in case of a Time Out - we have checked it x1000 of times and it seems to be a rare issue.

Thanks Nir,

I really appreciated that this feature will be added.

The time out will be highly dependent on network/isp and location. For example, I am receiving it constantly with my ISP when I am attempting to connect to an Azure server in the USA. This is quite a distance from Australia and my ISP may not be the best during heavy traffic times.

Hi Nir,

I am curious if this made it to the latest service pack update 1.0.0.10.0 .... I have looked at the documentation for the sl_SetSockOpt method and do not see this option available.

Hi Glenn, We have increased the TimeOut from 5Sec to 30Sec - this is hardcoded and not configurable. It's documented in the Release Notes. I hope it answers you query. Best Regards, Nir Nitzani

Thanks Nir,

I have just tested and everything now works! Thanks so much, this has resolved an annoying issue that was caused by my ISP. I should have reviewed the Release Notes.

Hello,

I'm using servicepack_1.0.1.6-2.7.0.0.bin.

I'm sometimes getting error -462 (connection timed out due to handshake time) as a return from sl_Connect() after much less than 30 seconds

I'm using a secure socket (TLSv1.2) and a non-blocking socket by making the following calls before calling sl_Connect():

int retVal;
long lNonBlocking = 1;

n->my_socket = sl_Socket(SL_AF_INET, SL_SOCK_STREAM, SL_SEC_SOCKET);
retVal = sl_SetSockOpt(n->my_socket, SL_SOL_SOCKET, SL_SO_NONBLOCKING, &lNonBlocking, sizeof(lNonBlocking));

I'm wondering if using a non-blocking socket affects the handshake timeout? Why would there be a timeout when using non-blocking sockets?

Best,
Danny

Anyone?

Come on guys, this is a pretty critical issue, as the subsequent open call results in a -400 (out of sockets) and we have to reboot. We're patient, but this is way too long to wait for a reply.

Hi Iain,

This thread was answered two years ago, and it looks like you are seeing a different error code than the one discussed. Please post a new thread with your issue in more detail.

Best regards,
Sarah
