Hello BIRD is running on Linux or on BSD? The second working session also uses MD5 password? The other BIRD server uses the same kind of hardware (esp. the network card)? We heard about such kind of problems with MD5 checksums, but as it is handled almost completely by OS kernel, i would guess that the problem is there (probably in some network card IP offloading or in some firewall rules). -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: [email protected]) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
