SSH connection for AT91SAM9261 controller
Hi guys,
I am facing a problem while implementing the SSH connection to my board and I am just one step away from my goal.
Actually the problem statement is as follows:
I have an embedded development board based on AT91SAM9261 microcontroller. The cross compiled openSSH have been installed in the folder /usr/local/bin and /usr/local/etc.
Following is the snapshot
- ~ $ ls -l /usr/local/bin/
- -rwxr-xr-x 1 root root 157786 Feb 23 23:01 scp
- -rwxr-xr-x 1 root root 245720 Feb 24 01:18 sftp
- -rwxr-xr-x 1 root root 3074202 Feb 24 01:20 ssh
- -rwxrwxr-x 1 root root 2392577 Feb 14 2017 ssh-add
- -rwxrwxr-x 1 root root 2290887 Feb 14 2017 ssh-agent
- -rwxrwxr-x 1 root root 2551181 Feb 14 2017 ssh-keygen
- -rwxrwxr-x 1 root root 2404513 Feb 14 2017 ssh-keyscan
- -rwxrwxr-x 1 root root 3250915 Feb 14 2017 sshd
and for /usr/local/etc:
- ~ $ ls -l /usr/local/etc/
- -rw-r--r-- 1 root root 242153 Aug 30 2012 moduli
- -rw-r--r-- 1 root root 1574 Oct 9 2013 ssh_config
- -rw------- 1 root root 668 Feb 25 03:09 ssh_host_dsa_key
- -rw-r--r-- 1 root root 603 Feb 25 03:09 ssh_host_dsa_key.pub
- -rw------- 1 root root 227 Feb 25 03:10 ssh_host_ecdsa_key
- -rw-r--r-- 1 root root 175 Feb 25 03:10 ssh_host_ecdsa_key.pub
- -rw------- 1 root root 672 Feb 25 03:15 ssh_host_ed25519_key
- -rw-r--r-- 1 root root 603 Feb 25 03:15 ssh_host_ed25519_key.pub
- -rw------- 1 root root 1679 Feb 25 03:04 ssh_host_rsa_key
- -rw-r--r-- 1 root root 395 Feb 25 03:04 ssh_host_rsa_key.pub
- -rw-r--r-- 1 root root 3646 Feb 27 07:06 sshd_config
- -rw-r--r-- 1 root root 3646 Feb 27 06:56 sshd_config_ori
Here you can see that I have done almost everything.
when I run ssh on my linux development board I get this :
- ~ $
- ~ $ /usr/local/bin/sshd
- ~ $
- ~ $ ps | grep ssh
- 893 root /usr/local/bin/sshd
- ~ $
- ~ $
this means the SSH is running on my board.
Now the case is that my embedded linux does not have any login screen and open up into the root screen automatically like this after booting the linux:
- rtc-rx8025sa 0-0032: setting system clock to 2022-02-27 19:37:04 UTC (1645990624)
- yaffs: dev is 32505862 name is "mtdblock6"
- yaffs: passed flags ""
- yaffs: Attempting MTD mount on 31.6, "mtdblock6"
- yaffs_read_super: isCheckpointed 0
- VFS: Mounted root (yaffs2 filesystem).
- Freeing init memory: 120K
- running /etc/init.d/rcS
- starting udevd...
- cannot open /dev/null
- eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
- eeprom initial complete
- /opt/apache/bin/apachectl start: httpd (pid 864) already running
- running /etc/profile
- route: SIOC[ADD|DEL]RT: Network is unreachable
- eth0: link down
- ~ $ eth0: link up, 100Mbps, full-duplex, lpa 0x45E1
- ~ $
- ~ $
Now when I try to connect to the linux board from my computer through SSH than it asks for the password for the root of the embedded linux board. But I don't have any and therefore it terminates the SSH session after three trials of password like this.
- piyush@piyush-System-Product-Name:~$ sudo ssh root@192.168.18.32
- root@192.168.18.32's password:
- Permission denied, please try again.
- root@192.168.18.32's password:
- Permission denied, please try again.
- root@192.168.18.32's password:
- Permission denied (publickey,password,keyboard-interactive).
- piyush@piyush-System-Product-Name:~$
so whenever I try to execute the command passwd to create the password I get following error:
- ~ $ passwd root
- /etc/passwd: /etc/passwd: 1: root::0:0:root:/:/bin/sh: not found
- /etc/passwd: /etc/passwd: 2: bin:*:1:1:bin:/bin:: not found
- /etc/passwd: /etc/passwd: 3: daemon:*:2:2:daemon:/sbin:: not found
- /etc/passwd: /etc/passwd: 4: nobody:*:99:99:Nobody:/:: not found
- /etc/passwd: /etc/passwd: 5: sshd:x:74:74:Priviledge-separated: not found
So I want to know that how can I remove this problem for successful SSH connection establishment.
