Hi! I'm not an expert Debian user and would like to know which package may have the error? Openssh-server maybe?
The symptom: There are two users on a host 'debhost'. I make 'su' from'user1' to 'user2', and create a file on /dev/shm. I make 'scp' from another host for 'user2@debhost', but target is the $HOME and not the /dev/shm. Result: the file disapperars from /dev/shm. user1@debhost:~$ id uid=1001(user1) gid=1001(user1) groups=1001(user1) user1@debhost:~$ su -l user2 Password: user2@debhost:~$ id uid=1002(user2) gid=1002(user2) groups=1002(user2) user2@debhost:~$ touch /dev/shm/foofoo user2@debhost:~$ ls /dev/shm/foofoo /dev/shm/foofoo On the other host: kantal@Olympus:~$ touch barbar kantal@Olympus:~$ scp barbar user2@debhost: user2@debhost's password: barbar 100% 0 0.0KB/s 00:00 Back to the 'debhost': user2@debhost:~$ ls barbar barbar user2@debhost:~$ ls /dev/shm/foofoo ls: cannot access '/dev/shm/foofoo': No such file or directory user2@debhost:~$ uname -a Linux debhost 5.10.0-11-amd64 #1 SMP Debian 5.10.92-1 (2022-0 1-18) x86_64 GNU/Linux user2@debhost:~$ cat /etc/issue Debian GNU/Linux 11 \n \l Thanks, kantal
