Kernel is 2.6.3 AMD64 on Mandrake 10.0, ppp 2.4.2. I built this kernel myself to fix the 64-bit issues with ppp (fix previously reported.) When I have VPN up and run a browser, it will retrieve a particular page fine the first time. However, if I click the submit button on that page again (which transmits a bunch of data - I authored this page so know all about it) the browser just goes into continuous wait and never actually transmits anything. I see the following in dmesg: PPP generic driver version 2.4.2 ppp_mppe: module license 'BSD without advertisement clause' taints kernel. PPP MPPE Compression module registered Module ppp_mppe cannot be unloaded due to unsafe usage in include/linux/module.h:503 mppe_compress[0]: osize too small! (have: 1400 need: 1404) ppp: compressor dropped pkt mppe_compress[0]: osize too small! (have: 1400 need: 1404) ppp: compressor dropped pkt What is the appropriate fix for this? ifconfig shows an MTU of 1396 for ppp0. I tried specifying mtu 1500 when starting pppd, but it still ends up 1396. I suppose the server end is constraining it. Appreciate all suggestions - I can rebuild the kernel if necessary. -- Guy Rouillier
