General :: Settings - In My Server The Iptables And Ip6tables Services Are Not Running ?
Jan 25, 2011
In my server the iptables and ip6tables services are not running. But still i am getting some iptables and ip6tables related alerts on my /var/log/messages. My technical leader told me that there might be some mis-configuration in iptables configuration file. But i didnt see anything wrong.

I am trying to run two different copies of vsFTPd service in the same server, one for IPv4 and the other one for IPv6. Because as I know that you cant run one vsFTPd server for IPv4 and IPv6 in the same time.

i know that there is already a command for it but it comes out with a lot of letters that makes it hard to find the services that are runningi'm talking about services like DNS, APACHE, DHCP, SAMBA, SSH etcis there a command that will list these services and related services that are running instead of showing a bunch of jumbled and lettered mess thats hard to comprehend

I have installed release CentOS 5.5 w/ fetchmail services. I've already configured the /.fetchmailrc in the correct format that I've learned from topics and I've checked also the sedmail running status. When I invoke the #fetchmail command this often happens:
fetchmail: WARNING: : Running as root is discouraged.
2 messages for user1 at mx.mailserver.com.ca: (1 of 2) (4353 octets) .....flushed
I have configured two NIC 's One for the public IP and another for the local network, I've tried to use the two IP's in the POP3 and SMTP settings of Mozilla Thunderbird but still user1 can't get messages.

I'm running Ubuntu 9.04 and started messing around with my firewall, it got a little too complecated for me, so I just would like to be able to somehow restore the default iptables setting. Any idea how I can do this?

I have been trying for days now to get this to work. didn't want to bother people with my questions, i have installed Fail2Ban 0.8.4 on CentOS 5.4.
I get the email notifications from Fail2Ban stating that it just blocked another IP, however, when i look at the iptables through webmin, nothing is actually in there, also the log/secure file dose not show that the ip has been blocked.
Even when I try to log-in with the wrong password, after a few tries i get the email telling me that my ip is blocked, however, I can still SSH using my 'blocked' IP.

I'm trying to open up some ports to connect via vnc to a server running Centos 5.5. I've edited /etc/sysconfig/iptables everything *looks* fine, but I still can't seem to get access to the port I've opened (I added some newlines for clarity between commands):

I'm having problems with hackers from across the globe trying to get into our servers. Why? i have no clue. nothing of value in my servers worth getting.
Right now my service only does business with USA. So I'm trying to find a way to block all Non USA traffic. I called my hosting provider and they are unable to help. Said it was up to me to do this.
Well I've already taken care of the TCP Wrappers. by spawning a small C program i made that uses MaxMind's GeoIP system. to automatically deny access. Now i need to do something about all the other network connections that come in to services that do not use the TCP wrappers.
So i was wondering if IPTABLES have a way to spawn a sub proccess like TCP wrappers or if there was any other firewall software out there for linux that would let me achieve my goal.

I want to simplify some of my rules, so I want to create rules for certain services like xmpp, web, etc. since some of them use multiple ports, and I toggle them on/off a lot. Can I simply put the jump to rule clauses in the Input chain, and once the sub chains run, does it return to the input chain after the jump to rule clause? I want to do this so I don't have a ton of rules in the input chain. I think that if I simply make a list of all the rules to jump to in the input chain, it will work itself through all of them until it finds a matching filter in one of them correct?

I have been trying to get my Samba 3.x NAS to connect to my Windows XP laptop. I can see the server though I cannot open it and see the shares. I have run various tests on the network and Samba (ping, smbclient) though still cannot find why I can't connect.
I can access the NAS via webmin, so I am thinking I need the security or the services settings on the XP machine. Is there a list somewhere of the Windows XP services and security settings required to share files?

We have our web site hosted by Go daddy and they provide us with the mail service as well. But there are a lot of constraints with the mail service with regards to the number of mail boxes, size per box, relays per user and so on.To avoid this, we are looking at other options. One is to have our own mail server but it will require a lot of infrastructure and expertise. But Amazon web services looks nice. They have infrastructure needed and all. One thing on my mind is the reverse look up of the mail servers. They wont be associated with the domain as both would be on different hostings. I am open to both windows exchange server as well as Linux server. Has anyone done this before or has any idea about it? I have gone through some of the threads in their forum and there are a lot of mixed views about it.And main concern everyone views is the reverse lookup. This could lead to all the mails sent from my server tagged as spam at the recipient end.I could not make out in which forum to write and hence in newbie. If this is enough about networking or server please move it.

After upgrade of 11.1 to 11.2 I noticed that none of services that was started in 11.1 at boot are starting now in 11.2. I check run-level of services with
Code:
chkconfig --list
When I start services manually everything is OK, but on restart they do not starting. Another weired thing is that my SuSEfirewall2 is filtering everything on input, nevertheless my previous configuration is still there, but ports are closed.

I need to start an application (graphical) when the PC start, even before anybody login, and use/launch a specific user. Now only can do this manually; when gdm starts, switch to any text tty [ie. Ctrl + Alt + F1], then I login into the special user, start a X server, export the DISPLAY environment variable, and start the application.
With this steps:
Code:
$X :1 -verbose -nr -nolisten tcp &
# Maybe Metacity -> $ metacity
$export DISPLAY=:1
$JavaApp &
Now i need put this steps (script) in some place to launch the app automatically, and with and specific user [ie. manager].
How can I made it? Maybe in init.d? or an special xinitrc? And how can start the app with the specific user? And, if is possible, who can stop the app when the system going turn off? I have Debian 5.0 and a beginner knowledge of shell script.

I'd like to run a Tor relay, but am trying to understand the security implications. For some time I've run my torrent client in a VirtualBox virtual machine, which is run as a very non-prived user, bridges directly to The Internets, and writes to one directory on the host. My belief is this is about as secure as it can be, but am open to suggestion.If I run a relay in the VM it wouldn't be associated with my use of Tor as a client, which is fine since there is no technical need for them to be connected and it's desirable for security.I read that chroot jails can be broken, particularly when run as root, so I don't really trust that. Also studied a vserver, but it must share the network setup which doesn't strike me as isolated enough.

I am baffled by fedora's feeble attempts to work with Samba. I have ran various versions of Fedora for the last few years, and sporadically, the Samba gui and samba itself have had such problems. My current problem in Fedora 11 (64bit) is that samba doesn't seem to be running correctly. It is allowing the hosting of shares, but it does not show that it is running in the services gui. It shows enabled, but when I attempt to change it by starting or stopping, nothing happens. The samba gui also shows that it launches but then never actually starts. I saw very similar problems with Fedora 9.

Last time I installed the ATI graphics driver on my PC, it was'nt working fine so I uninstalled that driver. I restarted the PC after uninstalling the driver but then, when PC boots and start running the services the screen just hangs and I don't get into the desktop.
I tried to run the xfs service using service xfs restart and also gdm service using service gdm restart, but in both the cases it shows that Unrecognized Service. So, I think it means that the package for xfs and gdm service is not available in my PC. Is that so?
I tried to get into the desktop by running startx but it gave the following error :-
Fatal Server Error: no screen found
consult the fedora project support at [URL] for help.
check the log file at "/var/log/Xorg.0.log" for additional information.
giving up
xinit: connection refused (errno 111): unable to connect to X server
xinit: no such process (errno 3): server error.

I have a little bit of a problem, I run openSUSE as a server on a Dell PowerEdge T610. I use it for sharing files in a local network and as a web server accessible through the public IP (configured through router DMZ). Also, I use Teamviewer for remote control in order to avoid some compatibility and network problems. Generally the computer runs flawless but from time to time, as about once in two weeks, all network related services except the Apache server which runs just fine, and is still accesible, crash. The Samba share can't be accessed anymore, the Teamviewer is also dead and the only way to put everything back in order is a restart. The thing is I don't know if an error occurs since the server hasn't got a monitor installed, and more than that I do most of my work remotely (as in miles and miles away from the location) and it takes me quite some time to actually get there and see what's happening.
So, any ideas what might be happening? I belive that there might be some information in some of the logs, but as I am not an expert in Unix like operating systems I don't exactly know where to start from.

I downloaded the latest 10.4 server CD with the intention of running a small Ubuntu Enterprise Cloud. I am following the directions here: [URL] Ive got 2 laptops that are capable of the tasks assigned to them. Both have dual core Intel chips that are VT enabled, 4GB of RAM, 250GB hard drives. Ill use one ( "server" ) as the front end server running cc, clc, walrus and sc.The other one ( "node1" ) will be the only node controller on my little network. Ive also got another laptop as a client, running euca commands to make instances and what not.These three laptops are connected to a switch. server is 192.168.1.100, node1 is going to be 192.168.1.110, the client laptop is 192.168.1.120.
the server seems to install fine, I select Install Ubuntu Enterprise Cloud, use it as the Cluster, give the cluster a name and 10 IPs to assign, 192.168.1.150-192.168.1.160 After the server is done installing and reboots, I boot the node machine off the CD and again select Ubuntu Enterprise Cloud. It's at this point the install craps out, because it does not recognize a cloud computer on the network.
Indeed, as I go to the server I run
Code:
ps -aux | grep euca
and see nothing running. So I start the eucalyptus service, and run
Code:
sudo euca_conf --list-clusters
and nothing shows up. Ive done some googling, ran some more euca_conf commands, registering the cluster, enabling walrus, cloud and sc. I can access the web gui on the client laptop, then restart the node install on the node laptop. This time it does see the server as a cluster controller, but when it tries to fetch the preseed file, it seems to not know the cluster's IP, as the red box that complains about the lack of a preseed file lists the URL as [URL] ( or whatever the file is called, I dont have the error in front of me. )
