RedHat Linux v. 5.1 has a serious problem in it's networking. I found
|
|
this out by sending a few messages to the rlogind port, (port 513) on my
|
|
Linux box after seeing it mentioned in my /etc/services file. What happened was
|
|
: I was looking through my /etc/services file when I saw an entry named login.
|
|
I noted the port number then switched to another virtual terminal. Then I
|
|
telnetted to port 513 and entered the user name root. The thing just
|
|
disconnected me, so I tried again using my non-priveledged account confucious.
|
|
Still no feedback. Naturally I gave up on that being very useful.
|
|
|
|
Later on, I figured that I would make a few changes to my bootloader, so
|
|
I tried to su to root. Alas, that did not work. So I logged out then tried to
|
|
log back in as root. Still didn't work.
|
|
Here is a transcript:
|
|
|
|
[confucious@localhost /]$ su root
|
|
su: invalid password
|
|
|
|
## This seems wrong because su usually asks for a password.
|
|
|
|
[confucious@localhost /]$ exit
|
|
logout
|
|
|
|
## clearscreen

Red Hat Linux release 5.1 (Manhattan)
|
|
Kernel 2.0.35 on an i586
|
|
|
|
login: root
|
|
|
|
Invalid Password.
|
|
|
|
login: confucious
|
|
|
|
Invalid Password.
|
|
|
|
## This is extremely weird as I haven't even entered a password yet!?!?
|
|
|
|
And this is what happens when you send shit to Port 513 on RedHat 5.1. Damn!
|
|
Also, this problem was not fixed by reboot. I had to re-install to get it
|
|
working again. Now wouldn't that piss you off?
