Hi, I fail to login with ssh client to dropbox I use Udoo ARM board with busybox to install ssh server I cross compiled dropbear under VirtualBox lubuntu and install binary to board ( /bin & /sbin) I generate RSA key (ssh-keygen -t rsa ) under lubuntu and copied content to /home/root/.ssh/authorized_keys on Udoo board I run on Udoo board : dropbear -vFE On VM lubuntu : ssh -vvv root@192.168.0.2 I add trace on dropbear sources and found problem come with function getpwnam to read /etc/password with errno=0; pw = getpwnam(username); dropbear_log(LOG_WARNING,"LBR %s %d %s",__FILE__ ,__LINE__, strerror(errno)); if (!pw) { return; } [157] Jan 01 01:06:50 LBR common-session.c 595 No such file or directory So it seems, there is problem to read /etc/password ? It well located in correct folder : ~ # ls -l /etc total 28 drwx------ 3 root user 4096 Oct 29 2018 dropbear -rwxrwxrwx 1 root user 192 Oct 28 2018 fstab -rw-r--r-- 1 root user 23 Oct 29 2018 group -rw-r--r-- 1 root user 10 Oct 29 2018 group- drwxrwxrwx 2 root user 4096 Oct 28 2018 init.d -rwxrwxrwx 1 root user 313 Oct 16 2018 inittab -rw-r--r-- 1 root user 34 Oct 29 2018 passwd ~ # cat /etc/passwd root::0:0:root:/home/root:/bin/sh Below are logs for client & server If you can jelp, thx in advance Laurent
