Or, rather, I assume anything       can happen.              So I wouldn't set the MTU to X unless I could be sure all other hosts       were set to X too, and that X is in fact supported by the medium.              Are you doing this out of curiosity, or are you trying to solve a       problem?              /Jorgen              --        // Jorgen Grahn |
