You login with a normal terminal like the ssh command or putty and not scp (scp is not working with chroot shell)? Any errors n the Linux syslog or auth.log file?
I am trying with putty. So if I want to say transfer file from my windows pc to server, how I can do that?
Yes. no error in the logs. only in the putty terminal I get access denied. once I change the chroot shell to none, I am able to login without any issue.
Please take a look in the /etc/passwd file of the server and post the line of the affected user (username can be changed) and the line of the web user of that site.
The relevant line in /etc/passwd looks like this web13:x:5011:5006::/var/www/clients/client2/web13/./home/mywebpawan:/usr/sbin/jk_chrootsh
that's ok. But there must be another user, the one that you use for login and that you created in ISPConfig.
