How Can I Set the FTP Welcome Message?

I want to be able to change both the initial message displayed when a user opens an FTP connection to my system and the login message. I know this is supposed to happen in ftpaccess, but I can't for the life of me find the files referred to in the configuration files /welcome.msg and .message. Is it that these files simply don't exist, and the messages displaying are defaults? Help. —Jon Dewey, jmdewey@clunet.edu

These files exist in your anonymous ftp area. On Red Hat this is usually /home/ftp. If you place a text file called welcome.msg in that directory, it will appear when someone anonymously logs into your machine. —Christopher Wingert, cwingert@qualcomm.com

Wiping a Hard Drive MBR

I can't install Linux due to an MBR problem and the message RAMDISK: Compressed file at block 0.

I have tried to cfdisk but no luck. I tried all sorts of boot/rescue diskettes without luck for two years now.

How can I wipe this hard disk clean before I install RHLinux? —Joseph Lalingo, joseph.lalingo@ablelink.org

You can wipe the MBR with lilo -u. —Christopher Wingert, cwingert@qualcomm.com

Kernel Panic on Boot

I installed Red Hat 7.0 as a dual boot with Windows 98 on my Toshiba laptop. Now when I boot, I am unable to get to either operating system, just a series of bracketed numbers, and the following message:

Code:89 02 85 c0 74 03 89 50 04 b8 01 00 00 00 eb
  03 90 31 c0 c7
Aiee, killing interrupt handler
Kernel panic: Attempted to kill the idle task!
In interrupt handler - not syncing

I am unable now to boot from diskette or CD-ROM. —Neil O'Connor, bowstn@yahoo.com

Boot your laptop using the rescue floppy created at install time, and run /sbin/lilo. This will reinstall LILO, and you should be able to boot from the hard disk again. —Usman S. Ansari, uansari@yahoo.com

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
