Login uncorrect from serial connection and correct from ethernet connetion
Added by Silvano Bertoldo over 10 years ago
Dear all,
I have a strange problem.
I hava my MityDSP connected to my pc through both a serial cable and a ethernet cable.
The MityDSP works good. I installed the kernel on the SPI-FLASH and the file system in .jffs2 format on the nand and I correctly set up the network address of the system.
I use the serial cable to configure some boot parameters on the Mity, but when the boot is completed I cannot make the login to the system using the serial connection. It shows me "Login:", i write "root" and it gives me "Login incorrect". That happens only with the serial cable.
Using the ethernet cable and ssh connection it shows me "login:" I write "root", it asks me the password, I write it and I can login to the system.
Why does this strange thing happens?
My boot parameters are the following, correctly saved on the uboot environment.
setenv bootargs mem=96M console=ttyS1,115200n8 mtdparts=nand:128M(rootfs),-(userfs) root=/dev/mtdblock0 rw,noatime rootfstype=jffs2 ip=${ipaddr} ip=192.168.1.44:192.168.1.1::255.255.255.0::eth0:off
My someone help me?

Does anybady has any suggestion?
It is important for me, not only to have the access from ethernet, but also from serial cable...

Did you set a password for the root shell? Normally there is no password by default. How did you set the password?

Normally, this is not a problem. can you check if there is an /etc/securetty file ( http://www.faqs.org/docs/securing/chap5sec41.html )
or log in over the network and then try to log in from the serial console and check the log files in /var/log for errors (and report back)
cheers

From serial I do the access without password but when I write "root" at login it tells me "login incorrect".
From ethernet cable I do the access with "root" and password "mitydsp" but I do not set anything.

Attached you can find:
- a startup screenshot;
- the content of /etc/ folder;
- the file securetty.
Let me know, thanks.

Is there something wrong?
Any idea?

Testing this on a L138 at my desk. I am able to login as root over ssh using any password including an empty password. But am having no trouble logging in over the serial port.
After setting a password I can no longer login using any password and am still able to login using the password on the serial port.

I updated to the latest filesystem and got similar results to my previous post.

My securetty file has following at the top of the file which i didn't see in the file you posted.
# /etc/securetty: list of terminals on which root is allowed to login. # See securetty(5) and login(1). console

Silvano, as a test, you can rename the securetty file which should eliminate any restrictions on root logins.
