Hi! Using bird for OSPF I've found that after two fast and consecutive configuration reloads (using birdc, command "configure") the md5 authentication fails, logging something like that: 18-07-2005 16:21:16 <ERR> Bad OSPF packet from 192.168.1.20 - authentification failed 18-07-2005 16:21:16 <ERR> Bad OSPF packet from 192.168.2.20 - authentification failed ... As side effect the bird process on other OSPF nodes die with signal 11 (!) All works again if bird is restarted on the reconfigured node and on the others who died. The password config section on the ospf protocol defined is something like: ... interface "tun*" { authentication cryptographic; passwords { password "verysecretindeed"; }; }; ... Do you any issues on stability of bird using birdc to reload configuration and such? Thanks in advance. Roberto -- Roberto Moreda Allenta Consulting UNIX, Linux & Security Services
