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). > If the session is already established, and you aren't using "bash" > as your shell, then typing "^C" might get you a default prompt and > drop you to a shell. No, that doesnt work. Even "ctr-alt-del" does not have an effect. > Alternately, you can run a split horizon DNS and/or a local caching > DNS server with a preloaded cache for all local machines to avoid a > real DNS lookup. Maybe an entry in /etc/hosts ? I will try this, because it is a good idea regarding to "stupid shells" ;) Andy -- Andy Hilker -- mailto:ah@cryptobank.de http://www.cryptobank.de -- PGP Key: https://ca.crypta.net
