Monks,

I seek advice about writing a login script. I work in a UNIX environment of about 1700 servers, mostly SUN running solaris 5.8, and IBM running AIX 5L. The criteria for my script is as follows:


  • Preferrably ssh to the requested server or telnet if it is not installed. Install ssh package if ssh is not installed.

  • If ssh is installed, the script should copy my rsakey from my home directory to the remote server to allow login without a password.

  • Log all hosts that have ssh installed with RSA key added so the script knows when not to use a password.

  • Encrypt my password when sending via Telnet i.e. MD5, RSA

  • su to root and drop into interactive mode after completing the above. (Expect?)

    • Any suggestions on how I would complete the above would be greatly appreciated. Modules used in the past, scripting methods, etc.. My scripting skills leave something to be desired, but I believe this may help future endeavors.

    Thanks in advance,
    /dev/null
