Subject: Report from after I have run Nessus.
Date: 23 May 1999 23:32:05 GMT
Hi!
I've just runned Nessus on a Red Hat v6.0 and got this messages.
* printer (515/tcp) INFO You should check that the remote printer service (lpd);is
correctly configured to accept print requests only;from a restricted panel of hosts.
What I did to the above message was that I created a file called /etc/hosts.lpd and
put my hostname in it (thunder.mil). Is that the right way to fix this?
* (6000/tcp) REPORT On this machine, there is an X11-Server that grants access;without
authentification. That means a hacker is able to sniff;every keystroke that is typed
on the X11-Server (or get a copy of the victims screen).;Solution: use MIT-Cookies,
xauth. ;
I thought that Red Hat did this as default. I checked the file /etc/X11R6/bin/startx
and it has the -auth switch. So what am I missing here?
* general/icmp INFO The remote hosts answered to an icmp TIMESTAMP request.;This will
give away the remote host current time to an;attacker, and this may help him to bypass
time based ;authentification protocols;Solution : configure your firewalls/router and
deny ICMP TIMESTAMP requests
What is the ipchain command for doing the above mentioned step?
(111/udp) INFO We could connect to the remote;RPC portmapper. This can give
away;interesting informations to an attacker;Solution : filter incoming traffic to
this port
What is the right command for doing this?
Thanks in advance,

I am using SuSe Linux 6.1 and just switched over from RH5.1 to this and
now I cannot seem to find a config tool to setup my computer for a DHCP
server. It asked me in setup for my hostname and domain name and I just
put something in but never gave me an option for DHCP access. Does
anyone know something about the Suse OS? or any other ideas please.
thanks in advance

Subject: User Setup Problem
Date: Sun, 23 May 1999 09:40:21 -0400
Can someone explain why I dont seem to be able to confer PPP, POP, or
any other priveleges to a normal user set up per my Linuxconf setup
menu. I go into Linuxconf, set up my normal user account and all the
appropriate buttons are clicked on, but when I run as user, I can't get
to my MODEM or anything else (Usernet tells me I have no access
priveleges available). When I am in ROOT everything is fine except for
the annoying fact that I cannot size my Netscape window to fit the
screen which is so annoying Ive gone back to Windows95 to surf the
Internet. SIGH.......
P.S.: RedHat has been ZERO help on all this of course, and their
manual totally opaque.
P.P.S.: I'm running Red HAT Linux version 5.2. I see 6.0 is out. Has
anyone asked why previous owners are unable to unpgrade either for free
or for a nominal sum ?

I am using kde 1.1.1 on SuSE 6.0. I have noticed on both my workstation and
my server that every now and then when I close out an application window
(like navigator or a terminal window) that my panel and taskbar will
disappear. I can't get them back unless I click on the icon to shutdown kde
and then restart it again. Has anyone else experienced this behavior?

You're right - it's in the init scripts. I haven't used Red Hat in a
while so I'm not sure which, but try to grep around for the one that
contains the offending line(s). I had to so the same thing once. :)

I use Redhat 5.1 and want to login to my home machine at certain times
only with mgetty.
I would like to know how the command line would read in a crontab to:
create the file /etc/nologin.ttyS0 at specific times and remove
the file
at the times that I wish to login.
I do understand the time part, but do not know how to create the (new)
file
in the command line.

You can purchase a EIDE BIOS upgrade card for around $20. DataTechnology
makes one called DTC 1181. But maybe you could flash the BIOS on the
motherboard to acheive the same thing.

Apache will retrieve the file from disk when needed. But Squid can be
configured to have a "memory" cache as well as a "disk cache". Given
enough memory, you get reasonably more speed, and it is the same thing
IIS does: Keep files in memory.

With Apaches mmap module, you can have the same thing without
squid. But there are other reasons why squid _may_ accelerate your web
server:
Apache has to do a lot of work (depending on the actual configuration)
doing uri/filename translation, detecting the right mime-type, looking
for .htaccess files aso. With Squid "in front" this work has not to be
done on every access.
If you have a lot of dynamic content, exspecially when using custom
modules with mod_perl or something, using Squid can reduce the
necessary Apache childs, especially if there are lots of "slow"
clients. This can reduce memory consumption. The same is true for
static content, but it does not have such a great impact (since
f.e. a mod_perl enabled can be really _big_, depending on what it does)

Faheem -
When you say you are logged in as root, do you mean that you have logged
into your X session as root, or have you logged into your X session with
a user account and then logged in as root (perhaps using sudo) in a
shell?
If the former, I have no idea.
If the latter, then your user account owns the display and must give
permission before another account can use the display.
The easiest way, and safe only if you are not on a network (since it
gives the world access to the display), is to enter
xhost +
from a shell under the user account.
See the man page for xhosts (although the man page pretty much assumes
you already know this stuff and just need the details).

You can use the touch command to create a null file.
~$ touch /etc/nologin.ttyS0
Will create this (null) file for you.

Subject: wxftp can't get remote directory
Date: Sun, 23 May 1999 18:52:52 -0600
I'm trying to get wxftp (GTK+ version 0.4.0) to work on my
home network. This machine is running linux (kernel 2.2.1)
and the other machine is running OS/2 with the OS/2 ftpd
server running. The wxftp window comes up fine, and I can
enter all the proper configuration stuff to access the other
machine, but wxftp always complains that it "can't open data
connection" to get the directory listing on the remote
machine, eg:
220 rhino_house.ibm.net IBM TCP/IP for OS/2 - FTP Server ver
09:39:01 on Mar 03
1995 ready.
SYST
215 OS/2 operating system
PWD
257 "F:\temp" is current directory.
PASV
227 Entering Passive Mode (192,168,0,1,5,2)
TYPE A
200 Type set to A.
LIST
150 Opening ASCII mode data connection for F:\temp.
425 Can't open data connection.
I can transfer files back and forth fine, but I can't see
what's in the remote directory, which makes it kind of
difficult at times. Other ftp clients on the linux machine
don't have this problem displaying directories on the OS/2
machine; eg NcFTP, ftp, etc. so I don't think the problem is
on the OS/2 machine.
Any ideas where the problem is with wxftp?

You can't mount it like a disk drive; these are streamers. You can
