similar to: puppet vs rhel4 system-config-securitylevel

I'm trying to NFS-mount a CentOS directory on my Fedora laptop, but I find I can only do this is I turn off the firewall on the CentOS server. If instead I go to system-config-securitylevel-tui on the server, and allow NFS4, this does not do the trick. Nor does allowing port 2049. What do I need to allow? [I should say that the CentOS server is remote, and difficult to access directly; that

Hi Ignacio, apology for my English... my name is George Ginis... what you mean running/accessible via firewall and system-config-securitylevel? in XP or CentOS? and what is this? the PuTTY I have in XP or in CentOS? thank for your answer... By default CentOS doesn't have ftp, telnet, nor rlogin services running/accessible via firewall. Use an ssh client such as PuTTY. And don't forget

Hi, I'm using the generic system-config-securitylevel-tui program on a remote server to configure my firewall. So far it's been fairly decent, allowing me to open up ports and whatnot. But I want to start blocking a couple of outgoing ports on my machine. I want to lock it down so the only traffic going in our out of my machine is stuff that I specify. Is there a way to do this

Hi, When browsing the (excellent) deployment guide I found the following broken links: http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-basic-firewall-securitylevel-enable.html ('Next' link from http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-basic-firewall-securitylevel.html) http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s2-iptables-options-commands.html

Hi, I'm using the preconfigured firewall that comes with CentOS 5. I configure it with system-config-securitylevel-tui, close all ports except SSH, and then open only the ones I need. Right now, on one of my desktops, I've installed AMSN, which requires opening a series of ports. I've configured the app to use ports 7000 to 7010 (TCP and UDP). When running

Hi, With the release of 5.2 "yum update" seems to be upgrading our computers from CentOS 5.1 to CentOS 5.2. I note from release notes for 5.2 that you are only supposed to get 5.2 if you type in "yum upgrade". On two seperate machines entering "yum update" has resulted in yum geting repo information for packages with versions that only exist in the base

Greetings: i have a pretty stock CentOS 5 machine with ports 80 and 22 exposed, so my /etc/sysconfig/iptables file is pretty standard/straightforward. my question is: how is this config file initially generated? i'd like to re-create it, and add a couple of rules .... so i don't want to lose what's in there already. i see that my /etc/sysconfig/system-config-securitylevel has

Hi, I'm planning to use CentOS 6.x on a handful of LAN servers. So far I've been using Slackware64 14.0 and 14.1 for the job. I wonder what's the orthodox/recommended way of configuring and iptables firewall with CentOS. I understand there's the system-config-securitylevel-tui NCurses interface which allows defining a basic set of rules. But what about the handful of more

Hello I have set up NAT with iptables for an openvpn connection, so that the VPN server could give VPN clients access to the entire sub-net of the server. The probelm is if I start system-config-securitylevel to say disable the firewall, and then again to enable it, my iptable rules are gone ! I did run `service iptables save` before. Is there something I can do to prevent this ? Is there a

Hello CentOS, I'm curious... there seems to be a couple of default firewall rules that I'm not familiar with in the CentOS 4.0 # Firewall configuration written by system-config-securitylevel # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD

So I use Samba on my home network. I open the samba ports in the GUI tool for CentOS 4. Here is the problem. Every time I reboot I'm forced to run system-config-securitylevel to get firewall ports open again. So like if I reboot samba won't work. I go into that tool either via command line or via the GUI and I simply click "ok" and samba is suddenly open. Does anyone know what

In following up on the rsh "problem" I was having earlier, I decided to try out the suggestion Felipe sent about using system-config-securitylevel-tui to open up ports 513 and 514, but that doesn't seem to do the job, either. # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination RH-Firewall-1-INPUT all -- anywhere anywhere

Hello everyone, I am setting up a new system for use as a testing/demo/trial-and-error system. I have installed CentOS 4.4 on it. There is not an X-environment, so I will need to fix this from the command line (via ssh access). I am trying to do an nfs export from this box to another on my internal home network. I have figured out that it is a firewall issue on the CentOS box (I turn off the

Might there be anything CentOS related on why I cannot access the Monit GUI system on http://box-running-monit.com:2812 ?

Okay, I just spent some time getting this done for a project. I documented the steps performed. Thanks to all of those who provided input.

Post Turkey Day (#1 Shopping Day) Greetings! I am running CentOS-3 as a desktop distribution. Everything is fine except for Idle, the integrated development environment that comes with Python. Python is version 2.2, but Idle is version 0.8. The Idle 0.8 keyboard is driving me nuts. On my Windows box, I downloaded from www.python.org and installed Python, and got Python 2.3 and Idle 1.0.8,

Hi, I've been contacted by a local training center specialized in Oracle databases, to train a group of four administrators to use Linux. They're supposed to use Oracle Linux (more exactly "OL5"), which I understand is some specialized version of Red Hat Enterprise Linux. I'm reasonably proficient with CentOS. I've been using it exclusively on desktops and servers

Hi, I have an existing iptables as follows:- # Firewall configuration written by system-config-securitylevel # Manual customization of this file is not recommended. *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :RH-Firewall-1-INPUT - [0:0] -A INPUT -j RH-Firewall-1-INPUT -A FORWARD -j RH-Firewall-1-INPUT -A RH-Firewall-1-INPUT -i lo -j ACCEPT -A RH-Firewall-1-INPUT -p

Here is a list of files that I have not (knowingly) modified that do not pass rpm verification immediately after I installed centos 5.3. I am not really sure what this means - are the packagers sending out sloppy rpms, or is something going around modifying stuff? Other than the texmf stuff, the list seems to consist entirely of config files. Does yum or rpm or something do some instant
