Original GitHub issue: https://github.com/netblue30/firejail/issues/339
ssh works well
my@my:~/$ ssh ssltest2@some
Last login: Mon Feb 29 11:47:32 2016 from from_host
46:bash:open /dev/tty:3
46:bash:open /etc/bash.bashrc:-1
46:bash:open /hsphere/local/home/ssltest2/.bashrc:3
46:bash:open /dev/tty:3
46:bash:fopen /etc/passwd:0x1891008
46:bash:open /etc/bash.bashrc:-1
46:bash:open /hsphere/local/home/ssltest2/.bashrc:3
46:bash:open /hsphere/local/home/ssltest2/.bash_history:-1
46:bash:open /hsphere/local/home/ssltest2/.bash_history:-1
46:bash:access /lib/terminfo/x/xterm-256color:0
46:bash:fopen /lib/terminfo/x/xterm-256color:0x1899808
Unfortunately neither scp or sftp works. F.ex. for scp
my@my:~/$ scp -P 8080 os.sh ssltest2@some:ssltest2.dk
Error: cannot find the program in the path
lost connection
/etc/firejail/login.users looks like
ssltest2:--private-bin=bash,sed,ls,cat,less,scp,wget,top,ps,sftp,slogin,nano,cp,mv,rm --private-dev --private-etc=group,hostname,localtime,nsswitch.conf,passwd,resolv.conf --private-tmp --nosound --noroot --seccomp --quiet --trace
Did I miss something in configuration or is it by design?

All fixed, give it a try. If there are still problems I'll reopen the bug. Thanks!
@bobykus commented on GitHub (Mar 3, 2016):
still an issue. here is what I did
git clone https://github.com/netblue30/firejail.git
cd firejail
./configure --disable-x11 --prefix=/usr --disable-bind; make; make install

If you remove private-bin from login.user, does it work?

@netblue30 commented on GitHub (Mar 10, 2016):
I am on Debian 8, with default sshd configuration and it seems to be working fine.
Did you modify /etc/ssh/sshd_config? Can you run it if you remove everything from /etc/firejail/login.users?
@bobykus commented on GitHub (Mar 10, 2016):
Yes, all is working fine. Thank you!
