    Try "cat /etc/shadow". If still blank, then your system has not been installed/configured properly. Is this a desktop/workstation/server, or is it an embedded system? Also, what Linux distribution and kernel are you running?

    It's an embedded system.
    Kernel 2.6.12 and busybox v1.00
    System was allowing to telnet earlier... suddenly after few days error occurred.

    Ok. It sounds like something nuked the shadow file. You may have to reinstall the OS, or restore the shadow file from backup. Is this running off of an SD card, or is it embedded (on-board) flash memory?
