I am trying to figure out how to turn my 10.10 server into a listener only. I have it set up using snort/acidbase. It is grabbing my network traffic just fine. I want to now set up a second server to hold all the data it collects. I need to change the snort server so it only listens. I disabled ping responses, but I want to go farther than that. I want to disable responses all together. I want it to only grab the data and store it.
I wish to use the VNC server built in to the Ubuntu to easily access it from other computers on my local network. I need to skew the VNC Server port off of the normal 5900 to something else because I am using VNC to access several computers (sometimes simultaneously) so each VNC server needs to be set with a different port #. At this point it is all local subnet connections with no incoming internet access and I am not worried about security.
I'm getting some problems setting up a Postgresql-8.4 server (using Debian Lenny). After have installed the PGSQL server, I've changed the following files as bellow code...
If you encounter this message, please check if the server you're trying to contact is actually running PostgreSQL on the given port. Test if you have network connectivity from your client to the server host using ping or equivalent tools. Is your network / VPN / SSH tunnel / firewall configured correctly? For security reasons, PostgreSQL does not listen on all available IP addresses on the server machine initially. In order to access the server over the network, you need to enable listening on the address first. For PostgreSQL servers starting with version 8.0, this is controlled using the "listen_addresses" parameter in the postgresql.conf file. Here, you can enter a list of IP addresses the server should listen on, or simply use '*' to listen on all available IP addresses. For earlier servers (Version 7.3 or 7.4), you'll need to set the "tcpip_socket" parameter to 'true'. You can use the postgresql.conf editor that is built into pgAdmin III to edit the postgresql.conf configuration file. After changing this file, you need to restart the server process to make the setting effective. If you double-checked your configuration but still get this error message, it's still unlikely that you encounter a fatal PostgreSQL misbehaviour. You probably have some low level network connectivity problems (e.g. firewall configuration). Please check this thoroughly before reporting a bug to the PostgreSQL community. This is the same configuration that I have in other Lenny server, which works well.
How can I set my server to listen at a different port for http access. I would like to use port 8080 (to circumnavigate isp blocks). Also can I do the same thing for sftp connections?
I'm running ubuntu 9.10, the box has 2 network interfaces. I've got rsyslogd running on this box also. On one of the interfaces I have a VoIP ATA which I've configured to send syslog messages to the ubuntu box, however they're not coming up in the log file (I've configured syslogd.conf to capture logs for local2.debug and local3.debug).
rsyslogd seems to be working ok for data coming through on the other interface, but not this one. I've verified the ATA is sending data by using tcpdump and have confirmed it's using local2.debug and local3.debug. It seems perhaps it might not be listening on all interfaces? rsyslog is running with the -c4 switch.
Client unable to listen to NIS domain server.I have configured an NIS server, which is working fine.I then configured an NIS client to share some like passwd, shadow, etc.By default the client was trying to communicate to the NIS server using the broadcast method..However if I restart the client computer, it fails to communicate or Listen to the domain server. Once I login to the pc, I then check the /etc/yp.conf file and it switched back to the broadcast method.Is there any way that I can make this entry: domain naman.com server station51.naman.com permanent so that even after the reboot it should communicate using the client-server connection rather than the broadcast connection.
Sometimes during bootup I get the following error:Starting Dovecot Imap: Fatal: listen(995) failed: Address already in useI tried to figure out what I could with the command lsof -i :995 and this was my output:COMMAND PID USER FD TYPE DEVICE SIZE NODE NAMErpc.mount 2936 root 7u IPv4 9201 TCP *:pop3s (LISTEN)When the system boots without the dovecot error the output of losof -i :995 is as follows:

I'm using OpenSuse 11.2 64 bits When I try to listen to music in Grooveshark Grooveshark - Listen to Free Music Online - Internet Radio - Free MP3 Streaming I can listen fine, and it seems to work ok, when suddenly the sound of the website stops to work, my processor gets overload and I've to reopen the site to continue to listen. I get the following message in kernel (I'm no sure if it's related)
We are trying to define an appliance based on Suse for an application server and Web server Apache, so we would like to know configuration best practices for network and security, is there any paper/doc about best practices?
I'm concerned about security of having a LAMP server on my laptop as having any server makes the system less secure. However, if I were to create a new partition and install a lamp server on that and only use it when offline, would the security of my main partition be affected at all?
I've recently been running a game server from my desktop, as well as a web page to accompany it.I use the ports 80/8123(HTTP)/5900(VNC)/50500(GAME)/5839(ADMINISTRATION).What's the best solution to protect my server from security threats? On a side note, I plan on adding a MySQL server later, but I want to keep it local only.
I'm new to server admin, so my question is based on what may be a bad assumption. With a server, my assumption is "if it ain't broke, don't fix it". In other words, I'm not really interested in upgrading the software to the latest and greatest if I already have stuff working on the server.
However, the one place where I DO want to constantly have upgrades is for security patches. How do I apply security updates to Ubuntu Server... and ONLY security updates?
I followed this how to to make a NFS server: [url]
So it means: exports looks like this:
Quote:
Here are some quick examples of what you could add to your /etc/exports
For Full Read Write Permissions allowing any computer from 192.168.1.1 through 192.168.1.255
It means that if sbdy arrives with a linux machine, puts the ethernet cable into the router, then logs as root on his machine, and mount the exports. He can do almost everythg, with permissions chmod'ing ...
Is that LAMP, or i am wrong for nfs kernel servers, the ultimate users/password servers against that to prevent those physical approches /logins?is there good how to ?
I want to know how can I test my server security with hping3 tool I want to make a virtual DoS or DDoS or SYNK attack in my LAN to test my server security and ability against these attack .Is hping3 a good solution for this or not if yes how can I do this which option of this can make such these attacks?
I'm running Ubuntu 9.10, and am trying to get proftpd to listen on a port other than 22. I've modified the proftpd.conf file, as well as adding the desired port to my /etc/services file, yet if I try anything other than port 22, the connection is refused.
I went on radio's web site to listen to it when i hit the link to listen to i get an error saying i don't have the required plugin and an option to search. I searched and i got this message
I am just a newbie here and I'm just starting to learn ubuntu, so be easy to me. So my question is how do I play this radio on my Ubuntu. Here's the links: [URL]
It appears that X Windows under Ubuntu (or Gnome?) is started to listen to a Unix named socket, instead of a TCP port number, for client connections. That's what SSH is forwarding when it does X forwarding. I need to start X applications on a remote machine, and then close the SSH connection. So I need to make the connections directly. This is within a LAN on private IPs, so security is not an issue. I searched on help.ubuntu, but there appears to be no particular document that covers this. Anyone know where this is configured to enable it to listen on a TCP port like the usual 6000?
So I installed ubuntu 11.04 x32 (using unetbootin-win-549) next to Win7. Grub installed correctly, it added the win7 boot-loader to the list. All I wanted to change was the default selection, from Ubuntu latest kernel to Win 7. I first tried StartUp-Manager but the settings didn't take effect (default was still ubuntu and timeout was still 10, not 5 as I selected). Then I went to manually changing the etc/default/grub with gedit only to find that the new settings where already written there. So I just ran update-grub and tried again. Still nothing.
My 3rd try has been with Grub Costumizer. Still nothing.the changes were there, I tried changing them a little but after reboot, Grub still had default settings. So my question is what am I doing wrong?
I am currently using a workaround by reinstalling win7 bootloader and adding grub to the list using easybcd. Which is good because win7 is the main os (for now) and it cuts a few seconds by bypassing grub. But I would still like to know what I missed. I've been reading through the "grub 2 basics" guide but I still can't see what I'm doing wrong.
SOLVED: I did two things today, 1. I reedited /etc/default/grub with "gksu gedit" (I've seen others use it, I have no idea what it does) it is probably not this what solved it anyway. The second is that I ran "update-grub" with sudo (doh), yesterday I forgot to put sudo but it didn't give me any errors, it looked like it updated with no problems (even "/boot/grub/grub.cfg" looked updated).
I have an account to log into Coasttocoastam Site and listen to the streaming audio. On windows it plays with either Windows Media Player OR Real Player. I've always just used Windows media player. Now that I'm installed Ubuntu 10.04 when I go the site. Of course I click it to copy what it's doing and XINE is displaying and I see it's buffering and then starts to play.
Is there a way to listen to listen to NPR on linux, and not through a browser? I could not get it working. What URL should I add as a radio station in Rhythbox, or a different player.
I imagine I'll have to install something, but Google has shed no light for me thus far. And just to clarify, when I say virtual terminal I mean the terminals accessed by CTRL+ALT+(F1-F6). I'm going to be doing a challenge/learning experience where I don't allow myself a graphical interface for a month. way around BASH through adaption. However, if I have to go a month without music I will go insane.
So, even if this is possible can I listen to music from the internet (....., playlist.com, etc.) or just music on my hard drive? And I'm not sure if this thread belongs in Desktop Environments or not, that section seemed to focus on graphical interface.
i just got this usb turn table and when im in windows, i can listen to the vinyls when they are recording. i was just wondering if i could do the same when in ubuntu.
Dear community, I am using the version 10.04 LTS of Ubuntu. I want to listen to an internet radio station, which I can listen without a problem in Windows. However, in Ubuntu nothing happens when I click the link. The URL of the radio station is [URL]. The link which starts the streaming has the words "RADIO EN VIVO".
Im trying to listen to this radio station using firefox but i can't. It has two versions the one on the left is for windows media player and the other one is something like the bbc radio iplayer i could listen to the iplayer version yesterday but something happened and now i just can't. Anyways i tried playing it using vlc
Code:
[URL]
but it seems even vlc cant play it heres the output
Code:

p { margin-bottom: 0.08in; } When I play my music using any application or I use anything that get out from the speakers I can't listen it smoothly. It is like a jump (silence) that occurred randomly. I have read the sticky (Comprehensive Sound Problems Solution Guide) where I learn that I have more than one on-board sound cards after:
I would like to listen to a virtual serialport (dev/ttyACM0). I heard you can this with the terminal in Linux. But how? Does anyone know some commands?
