Problema al conectar amb "scponly"
Hola bones,
Tinc un servidor SFTP molt registringit, dins una gàbia chroot, i els usuaris
tenen com a shell el "scponly"; pel mig hi ha un router Cisco Linksys
redirigint el port 22 cap el servidor d'SFTP.
Tinc molts problemes per accedir per SFTP desde fora la xarxa local, he de
intentar connectar 6 o 7 cops o més fins que no connecta. Desde la xarxa local
insistint un parell o tres de vegades n'hi ha suficient (potser és casualitat
que desde dins costi menys). El que m'extranya és que s'hagi de provar varis
cops abans no entra... curiós.
Desde terminal amb "sftp -vv usuari@host" treu:
debug1: Authentication succeeded (password).
...
debug1: Entering interactive session.
...
debug2: channel 0: rcvd close
...
debug2: channel 0: gc: user detached
debug2: channel 0: send close
Adjunto el log complet.
Alguna idea de per què se'm desconecta? Gràcies.
