| > BTW, I am using CCID3. | | Ok, now to the next troubleshooting test: can you please try using | CCID2? That way we can isolate the problem, is it CCID3 specific? | CCID2? Core? Something else? Yes, please do send all kinds of debug information which you encounter to the list; this makes tracking down the errors much simpler. Both CCID 2 and CCID 3 now have debugging options, CONFIG_IP_DCCP_CCID2_DEBUG=y CONFIG_IP_DCCP_CCID3_DEBUG=y but in order to get debugging output, these must be explicitly set via module parameter. This can be automated. If you paste the following into a file /etc/modutils/options, # options for DCCP options dccp dccp_debug=1 options dccp_ccid2 ccid2_debug=1 options dccp_ccid3 ccid3_debug=1 # EOF and run `update-modules' [alternatively: paste the above at the end of /etc/modules.conf ] The same options should also be placed into a file /etc/modprobe.d/options (if you are running modprobe); or alternatively into /etc/modprobe.conf (man 5 modprobe.conf). This all is important, much helpful output (e.g. DCCP_BUG(...)) depends on having debugging enabled. - To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
