    Hi Terry,

    first thanks for your answer.

    I have had this case once a time (nameserver was down). After a
    timeout (i think it was a reverse lookup from sshd), shell works.
    I am using zsh.

    This is no explanation for a crash (one apache is dead, ftp logins
    does not work, logins on local console does not work: after typing
    user and hitting enter nothing happened).

    No, that doesnt work. Even "ctr-alt-del" does not have an effect.

    Maybe an entry in /etc/hosts ? I will try this, because it is a
    good idea regarding to "stupid shells" ;)
