restricting sftp/ssh login access

Hi, I would like to know if there is a way to restrict user logins to their home directories (or any other designated directory for that matter) using sftp/ssh. I've got my ftp server configured so that normal ftp access is restricted to their home directories, but since sftp uses (Open)SSH, it

Hi, It sounds to me like you are looking for a chroot jail for some users. apt-get install jailer ( jailer - Builds and maintains chrooted environments ) You will need to run a special daemon (jk_socketd) to log users into the jail, but that is about the hardest part. I'll post my startup

The cleanest way I have found was using rssh. All you do is change the shell to /usr/bin/rssh. The only issue I have with it is that to jail them to their home directory you need a separate chroot for each folder of the following. I jailed the /home folder and thus only need one jail, if you

I agree that a jail is the cleanest way. My setup is as follows: chroot jail: /home/jailedUsers dirs and files within the jail: ./lib ./lib/libnsl.so.1 ./lib/libnsl-2.3.2.so ./lib/libc.so.6 ./lib/libc-2.3.2.so ./lib/ld-linux.so.2 ./lib/ld-2.3.2.so ./lib/libnss_compat.so.2

Have you tried iptables instead? If your kernel supports iptables, then: echo 1 /proc/sys/net/ipv4/ip_forward echo 1 /proc/sys/net/ipv4/conf/$both_eth_devs/rp_filter iptables -t nat -I POSTROUTING -s 192.168.0.0/24 -i eth1 -o eth0 -j MASQUERADE iptables also does the firewalling in other
