Very Computer

Here's the situation:  I run Linux on a firewall box, and wanted to
use ipchains to block incoming pop3 access (eth1 is my external
interface). The following line in my rc.local file:

ipchains -A input -p tcp -y -i eth1 -dport pop3 -j DENY

caused my boot process to hang.

The error, of course, is that it should be --dport (double dash), not
- (single dash)... but* the boot process for this seems pretty
extreme, particularly since if you enter it a command prompt
"manually" you get a basic error message!

Of course, this did cause me to learn a whole lot about single user
mode and remounting readonly file systems, so maybe it wasn't all bit
<sick grin>.

BTW - when you need to find out the maintainer of a component, the first
place to look is /usr/src/linux/MAINTAINERS.

I wonder if the behavior could be due to stderr not being handled
correctly. Oh well, at least I was able to work around it... although
for a moment there I thought I was dead, with no boot floppy
(embarrassed grin) and no idea how to get the filesystem into
readwrite mode!
