Hi and thanks Ian, I'm using the simple client/server application : http://wand.net.nz/~iam4/dccp/dccp-cs-0.01.tar.bz2 I work on Debian etch with default linux kernel which is 2.6.18 for now. I hadn't apply any patches yet, but I'm doing it today... I patched dccp module with patches 1 to 6 with a similar command than below Unfortunately, the 7th (07-2b_ccid3_tx-len-not-needed.diff) doesn't work : /usr/src/linux-source-2.6.18# patch -p1 < /tmp/patchDCCP/07-2b_ccid3_tx- len-not-needed.diff patching file net/dccp/ccids/ccid3.c Hunk #1 FAILED at 149. 1 out of 1 hunk FAILED -- saving rejects to file net/dccp/ccids/ccid3.c.rej Am I doing something wrong ? or is there any issues with this patch ? (and I guess the errors I get when I try the other patches come from this first problem) regards, Patrick. 2007/2/21, Ian McDonald <ian.mcdonald@xxxxxxxxxxx>:

It's in the source code tree and also on the Wiki you were looking at. cc'd dccp@xxxxxxxxxxxxxxx as this is where we can discuss more (as per Leandro) Ian -- Web: http://wand.net.nz/~iam4 Blog: http://iansblog.jandi.co.nz WAND Network Research Group
