I haven't come across this problem with Redhat 6.x Linux. Providing the
username and password are valid in /etc/passwd you should have telnet
access. You are not normally allowed to telnet in as root for security
reasons. It's best to telnet in as a user and then su - root as necessary.
Can you use telnet on a client locally ?
Have you checked that telnet is enabled in /etc/inetd.conf ?

In other words, in robots.txt you can specify parts of your web site that
robots should not download. For example it would make no sense for a robot
to download web pages produced by cgi scripts or submit forms. There is more
information in the documentations that comes with the wget function.

A running UNIX system will surely not allow you to overwrite the root
filesystem since it is busy serving the currently running processes (i.e.
they
have open files in subdirectories of /). The purpose of NFS is to share
common filesystems not to replace the local system (e.g. configuration files
are valid only on a specific system). If you are looking for diskless
clients,
you should consider cluster solutions (I tried that on HP/UX: booting from
network really worked).

Subject: Booting Windows 2000 from mkdosfs partition
Date: Fri, 31 Mar 2000 10:02:02 +0100
I have a problem when trying to boot Windows 2000 from a partition formatted
using mkdosfs.
I am writing a restore program that patches the boot sector with the
original Windows 2000 boot code.
I can boot using a FAT16 partition after formatting with mkdosfs, applying
the boot code patch, and then manually setting the drive number and hidden
sectors fields, however FAT32 is proving to be much more difficult.
I am still patching the drive number and hidden sectors fields (the drive
number is at a different offset for FAT32), but the boot code is hanging.
It makes no difference whether I delete ntldr, so the code isn't getting
that far.
Has anyone ever succesfully booted a Microsoft operating system that
understands FAT32 from a FAT32 partition formatted with mkdosfs?

Subject: RedHat gets "echo" wrong
From: [EMAIL PROTECTED] (Craig Macbride)
Date: Fri, 31 Mar 2000 09:30:48 GMT
The RedHat 6.1 man entry for echo claims that "Without -E, the following
sequences are recognized and interpolated:" and then gives the backslash
escapes that have been common in some Unixes for many years. However,
in reality, the echo command defaults to not understanding those escapes!
What's worse, the bash builtin doesn't recognise them either.
Does anyone know whether RedHat is likely to fix this error and whether
they'll change the man entry or the commands?
This situation is an utter pain for anyone attempting to port software
from other Unix platforms. The hard job of providing binary compatibility
with other x86 Unix variants has been done pretty well, yet the easy job
of providing compatible shells and simple commands has been screwed up
badly.
For those who don't wish to download the source and rebuild bash, is
there a version around which defaults to the desired (and documented)
action?

Well, not the best but probably the most easiest/quickest way: add
*.debug /var/log/counter
to /etc/syslog.conf and restart the syslog deamon by
kill -1 `cat /var/run/syslog.pid`
Now you can filter the popper use by something like
grep "<HOSTNAME> popper [<pid>]: connect from " /var/log/counter | wc -l
Hope this helps!

Hi,
I've done this loads before, but for the life of me I can't remember
fully the correct command now.
I want to kill telnet and ftp on my machine. I have edited the file
/etc/inetd.conf and commented out the telnet and ftp lines. It's the
next step I can't quite remember. I tried 'killall -HUP inetd' but that
didn't work. What am I missing?

Nothing. But when the client generates a 256-bit random number
(to be used as a session key for further communications) it
encrypts with this public key.
Only the host that has the corresponding rivate key can decrypt
it. So the fake server is no good at this point.

"man sshd" does not say what you are saying here. Here's the
relevant extract:
Sshd works as follows. Each host has a host-specific RSA key
(normally 1024 bits) used to iden- tify the host.
Additionally, when the daemon starts, it generates a server
RSA key (normally 768 bits). This key is normally regenerated
every hour if it has been used, and is never stored on disk.
Whenever a client connects the daemon, the daemon sends its
host and server public keys to the client. The client
compares the host key against its own database to verify that
it has not changed. The client then generates a 256 bit
random number. It encrypts this random number using both the
host key and the server key, and sends the encrypted number to
the server. Both sides then start to use this random number
as a session key which is used to encrypt all further
communications in the session.
So you see what get sent back as the first step is a host key
(fixed, well-known to all potential clients in advance, kept in
each client in the .ssh/known_hosts file), and a server key
(changes every hour).
The pieces of this which make for security are these:
(1) the client (you) does not blindly accept whatever PK was
sent as "host key". It compares it against it's internal
database (.ssh/known_hosts) which has presumably been
populatd via some reliable means at some point.
So a fake server sending you it's own PK, pretending to be
the real server, would be detected by the mismatch in the
PK you thought the host should have, and what it actually
sent.
(2) And of course, as I said before, if a fake server sends
the same PK as the real server's PK, the "known_hosts"
check woul match, but the fake server wouldn't be able to
decrypt the sessions key, which you (client) generated
randomly and encrypted with the host PK.
Hope this helps.
