Sie müssen nicht einmal einen Namen wie ssht verwenden. Namen, die mit Ziffern beginnen, auch nur Ziffern, sind gültige Hostnamen in der ssh-Konfigurationsdatei.

Welcome to Ubuntu 16.04.2 LTS (GNU/Linux 4.8.0-42-lowlatency x86_64)

Update - unten ist eine hackige alternative Lösung, nehmen Sie es nur für bashistische Übungen, vielleicht für schnelle und schmutzige Sachen:
alias ssht='f(){ ssh -p 22 said@192.168.0.$@;unset -f f;}&&f'
Was es macht
- Temporäre Funktion erstellen
- Übergeben Sie alle Argumente
- Stellen Sie die SSH-Verbindung her
- Deaktivieren Sie nach Beendigung der Sitzung die Funktion, damit sie nicht verweilt
- Es kann zusätzliche Argumente nehmen, das heißt , Sie können Kette zusätzliche ssh Optionen wie Tunneln (
-L
, -R
, -D
), ausführlichen Modus ( -vv
), nicht-TTY ( -T
) usw.
Zum Beispiel möchte ich einen Socken-Proxy ohne Terminal starten
$ ssht 2 -vv -D 1080 -T
