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

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)
