[scponly] sftp-server error "No such file or directory"

[Nick Payne-Roberts]

hi,



I have installed the scponly onto a fedora core1 system and have been
experiencing a problem when authentificating logon of a user which has been
set to the new scponly shell.



This is the following error i get when trying to log in using 'pics' user:

Also note that the user pics does exist also in the following passwd file.
btw, why do we need to have this here as well as using the normal
/etc/passwd file?



[/home/scponly/etc]# cat passwd

pics:x:518:519::/var/www/html/mortalis/pics:/usr/local/sbin/scponlyc

scponly:x:531:532::/home/scponly:/usr/local/sbin/scponlyc





Many thanks for any light someone can throw on this matter,
