/bin/mail is a binary file. If you have your OS RPMs run the following command:
rpm -Fvh This command if applied to all RPM stored in a directory or on OS CD, It will update ONLY the installed RPMs and will not change any system configs or file structures you have. The "echo" command is used to insert a comment/data to a file, so you have insterted somewhere in the mail binary file that line. Good Practice is to always safe your binary files to a floppy. It might be needed also if someone breaks into your box and attach some rootkit to one of your binaries to spy on your activities and passwords. Some tools that help in checking binary files integerity is chkrootkit (http://www.chkrootkit.org) or by using MD5 checksums to comapre with originals. To install chkrootkit, here is how: 1. First make a directory for chkrootkit: cd /home mkdir tools cd tools I think the latest version is 0.38 wget ftp://ftp.pangeia.com.br/pub/seg/pac/chkrootkit.tar.gz tar -zxvf chkrootkit.tar.gz cd chkrootkit-0.38/ make sense ----- Now you have chkrootkit installed under /home/tools/chkrookit-0.38 To run just type at shell prompt ./chkrootkit It is better to make a cron job that runs ckrootkit and sends you by email the results.
