I configured a tunnel where the server is a CentOS 5 x86_64 with compress. In the client don't have problem but in the message log of the server show this erro: vtund[15145]: segfault at 0000000000000040 rip 0000000000409774 rsp 00007fff88d548d0 error 4 I did the same configuration on another server, but i686 and had no problems. Packs: vtun-3.0.2-1.el5.rf x86_64 lzo2-2.02-3.el5.rf x86_64 Any idea? Thanks, -- Daniel Bruno http://danielbruno.eti.br danielbruno at projetofedora.org
