openssh unix dev - Feb 2006 - scp doesn't run in jail anymore

Hi *,

in Slackware 10.2, under scponly 4.6 chrooted shell, scp from openssh 
4.2p1 (scp.c,v 1.125 2005/07/27 10:39:03 dtucker) runs fine.

scp from openssh 4.3p1 (scp.c,v 1.130 2006/01/31 10:35:43 djm), however,
does not start (or maybe does, but doesn't report to my WinSCP client).

Under bash, both versions run fine.

Any idea / help ?
I'm ready to do any further testing / experiments.

Thanks,

Jan
