krijg geen toegang meer per ssh op laptop, terwijl eerder wel ...

[Y P]

Hallo,

Het beloofde feedback waarbij ik vorig weekend van een ultraplatte 13.3 inch
niet per ssh in een laptop geraakte, terwijl dit eerder wel ging:

raar maar waar, ik kan vandaag wel plots toegang krijgen per ssh, op de 
machine waar ik geen toegang meer kreeg; ik heb wel eens mijn knownhosts 
bestand onder ~/.ssh gedeleted, maar dat is alles, had dat ook eerder al 
gedaan...

In bijlage een typescript output met een ssh -vv.

(Jammer dat het probleem zich niet meer voordeed, want een probleem
dat zich sporadisch en bijna nooit voordoet, hoe kan je ooit de reden
achterhalen?)

Toch bedankt,

Y P

(bijlage)
