Re: Joiner for Linux

[Manuel Gomez]

Thank you for the responses, the document is openoffice (.odb), and i
usually use SFX compiler for Windows, but the result doesn't works in
Linux.

I only need that the document can be readable and writable, only this.

Thank you very much.

Joiner for Linux

[Manuel Gomez]

I am searching a joiner for Linux. I need to join an document with
another archive, and i want can open the document without problems.

I am not creating a trojan or something, its for add size to specific
documents (security-> If the document have 5 kbs it takes 5 sec download
it, but if the document have 500 mb it takes a couple of days, and i
turn off the connection constantly. Believe me, for me is usefull).

Somebody could help me?

Thank you very much.

Help - Restrict root privileges - What is indispensable?

[Manuel Gomez]

Hi, i would like to restrict the privileges of root. Now goes the
question: why?

I only need the essential for run my OS:

Can access to my frontend netfilter (iptables) shorewall.
Use chmod, run sh scripts, and any command essential for running the OS.

I would like more security, and i have to open gksu constantly, so i
have chossen this. I not going to use sudo because Shorewall doesn't
accept using it as a normal user.

How could I change /etc/sudoers?

Help - Adding size to a document? More security

[Manuel Gomez]

Hi, i would like to add more size to a document to avoid hackers. If the
size is too big, troyans won't download the archive (it would take days
and days...)

How could i do this? I am using "SFX compiler" for join an archive (3
gb, for example) with my documents, but i would like to know how its
done.

I need: Open the document (for example, dbs in openoffice) in Linux, and
more than 1 gb of size.

Thank you very much, I appreciate your help.

Limitar root, ¿idea exagareada? ¿Sugerencias sobre comandos?

[Manuel Gomez]

Buenas, estaba pensando sobre lo útil que sería para un SO que no
necesitase hacer cambios en los que se pueda usar root limitar el propio
usuario root. ¿Y si instalo todo lo que quiero instalar y modificar y
una vez terminado limito los privilegios de root? ¿Qué privilegios
serían indispensables de dejar aún así? ¿coo podría ser por ejemplo
ciertos comandos o cosas indispensables.

Muchísimas gracias por responder.

By using REJECT instead of DROP, you have no stealth. This means
you can be port-scanned to look for weaknesses, e.g. unpatched
OpenSSH vulnerabilities, etc. 



That said, if SSH traffic is blocked, an OpenSSH vuln. might not be 
significant. If you're allowing and inbound traffic, though, any 
unpatched flaws in the app servicing that inbound traffic could expose 
your system to attack.


Also, by REJECTing rather than DROPping, you might be more vulnerable 
to DoS attacks.


Consider using a default (LOG and) DROP policy instead. Michael Rash's 
site (www.cipherdyne.org ) has some good 
resources for learning about this and implementing it.

I have set the default policy in DROP.

What more could i do?

Thank you very much, i appreciate your help.

About my Firewall Settings - I would like an opinion

[Manuel Gomez]

Hi, i would like to read opinions about my firewall settings:


I am using Iptables with Shorewall (frontend) and my configuration is:


- Default Policy: REJECT all connections.


- Rules: Allow DNS (my DNS servers), allow http and https connections 
for servers: www.google.es, ...



So, nobody except these servers can connect with me (inbound and outbound).


This type of configuration is secure?  How could they attack me?


Thank you very much, i appreciate your help.
