On sftp linux server files are created with ------- permissions. What could be wrong?

Question

linux

SFTP server on SUSE Linux Enterprise Server 11 (x86_64) PATCHLEVEL = 1.
SFTP settings /etc/ssh/sshd_config

Subsystem sftp internal-sftp -l VERBOSE -f LOCAL6

Match Group sftponly
ChrootDirectory %h
AllowTcpForwarding no
X11Forwarding no

Settings in /etc/syslog -ng/syslog-ng.conf

unix-dgram("/home/user/dev/log");

host1:/home # ll
drwxr-xr-x 4 root root 4096 Sep 30 17:05 user

host:/home/user # ll -ls
4 drwxr-xr-x 2 root root 4096 Sep 30 17:05 dev
4 drwx- ----- 2 user users 4096 Oct 12 11:08 upload

The user walks on the key. Uploads files to the upload folder via sftp using the WinSCP client.

You get the following.

cat /etc /profile

umask 077

What could be the problem with creating files WITHOUT PERMISSIONS?

Answer 1

This is due to the fact that non-login non-interactive shells are created for the sftp session. For such a shell, the settings are taken from the ~/.bashrc file. To change the umask for the sftp session, edit the ~/.bashrc file as follows - find and comment on the following line (the line is at the beginning of the file):
#[ -z "$PS1" ] && return
Instead, write the following code (set the umask value that you need): After that, connect via sftp, create a directory and look with what rights it was created: We see that the rights correspond to the set umask 0007 parameter.
if [ -z "$PS1" ]; then
umask 0007
return
fi
