Re: [TEKNIK] ssh: kan ikke længere logge in d



Har du opdateret gnutls i dag eller i løbet af denne weekend?

Det er muligt...
- jeg har forsøgt adskilligt inklusive at hente bunken af opdateringer fra Ubuntu. Så om gnutls er blevet opdateret før eller efter mine problemer er ikke til at sige.

Nu hentede jeg lige seneste opdateringer.
Heriblandt var bl.a opdatering til ssh og til gnutls.
Men lige meget hjælper det.

Jeg har svært ved at tro at problemet som sådan er hos mig. Jeg har f.eks. også isat en live Ubuntu CD, og prøvet ssh derfra. Uden held.

På den server hvor jeg nu har problemer, har jeg tilfældigvis mulighed for at fejlsøge lidt. Jeg har root rettigheder. Men hvad kan jeg kigge efter?

Jeg har kigget i serverens /var/log/auth.log.
Der kan jeg godt se mine lokale ssh logins ( login fra en maskine der sidder på det lokale netværk ) men ikke nogen mislykkede logins fra min hjemme PC. Burde jeg det? Eller er der andre relevante logs?

Jeg gentager lige: Når jeg forsøger at logge på hjemmefra får jeg ikke nogen login prompt. Alt jeg får er:
