I have set up a gateway machine in debian lenny
internet is shared to the localnetwork by using squid as proxy server Can I improve the performance if I set up this machine as DNS cache server?
What is the result if I set this machine as Primary DNS?
I'm trying to setup a mercurial code sharing server on an Ubuntu machine but I can't figure out how to get it running. I'm setting up this server on a LAN so I don't want any security. Another thing I should mention is that I'm using Netbeans to code in Java. how use mercurial and tortoise (I've got them installed).

installing my APC Back-UPS ES 350. I am using CentOS 5 KDE setup as a DNS Resolving Caching Name Server, I wanted increase speeds and privacy since I got a letter and didn't like that not one bit, a tv show but whatever. It is very secure now, using peerblock with Iblock List subscribed to for the one year and it is so secure that I have to disable peerblock if I want to use online banking and what not.
setup the APC unit, haven't experienced APC and CentOS is new to me, I didn't want to buy a windows server, so I used BIND instead and well I love CentOS, can't wait to really understand it a lot better, also logging into root is so nice and easy vs Ubuntu, very cool.
I also do not have a DD-WRT supported router nor a Docsis 3 modem, docsis 2, I believe this should give me a lot more speed. currently I just get 11-17Mbps, I am hoping this will bump me back up to 35-37Mbps which I get off and on but unstable.
I set up a Samba server on my openSuSE 11.2 machine and I can connect to it locally with the local ip and with my actuall ip. My friend however cannot.

At present I am trying to setup a LAMP Server on an old desktop machine I have lying about, however there is not going to be a keyboard, monitor or mouse attached beyond the installation process. My question simply is am I best installing the server or desktop version of Ubuntu for this requirement?
I have been playing with Desktop 9.04 and found it tough to use headlessly, however understand that Server 9.04 fully supports headless access. Being a newbie I do prefer to use the GUI to make changes and generally play around, so a UI such as GNOME would be essential. Having read about I understand the best way to access remotely is to install SSHServer and VNCServer and then login over SSH and VNC into the box.My remote machine I will use to connect to Ubuntu is a Windoze 7/XP machine.
I need to access a Windows Server 2000 machine using a Linux machine via KDE, but that will migrate to Gnome. The Linux user to connect to Windows machine, you should open an application 'XYZ' automatically, and only this, denying any unauthorized access. When you close the application 'XYZ' communications (RDP?) Should be terminated. Do I need a log of accesses and possible attempts to circumvent the system and access other application.

View 1 Replies View RelatedI'm trying to setup and configure a server entirely with text only run mode 3 on a virtual machine so I can redo my current live server. I'm now trying to set up the firewall of the system using iptables. I've read up on it and came up with the following:
-clear all rules
#iptables -F
-set default policy rules
#iptables --policy INPUT DROP
#iptables --policy FORWARD DROP
[Code]....
Everything above worked for me but just out of interest I looked at my live server which was configured using a GUI. I ran iptables-save and it was pretty much the same but its port open lines read like this:
#iptables -A INPUT -p tcp -m state --state NEW --dport 80 -j ACCEPT
so finally my question is do I really need the "-m state --state NEW"? Wouldn't having that drop established connections on those ports? I'm just confused as to what exactly the NEW state is doing and would it make a difference if I didn't include it.

I have two Linux machines both running Debian (I do not want Windows to be involved at all). One is a desktop and one is a laptop. I desire to connect a not-yet-purchased printer/scanner combination machine only to the internal LAN via my router (Linksys WRT54G) via Ethernet cable, or via wireless if the printer/scanner has that capability. I want to be able to print to that printer (and scan from its scanner) by only having to turn on the printer/scanner and only one of the other computers, and not have to have both Linux machines turned on in order to print and/or scan.
So my questions are:
When I look at specific models of printers, what should I be looking for in their specifications that indicates that this configuration is possible (i.e., should I be looking exclusively for printers that say they are "wireless printers" or "network printers")?The reason I ask this question: In my online searching, I thought "networked printer" or "stand-alone network printer" meant just that, but what I found instead are pages and pages of instructions on how to connect the printer locally to a Linux machine, with the associated setup to allow that Linux machine to serve print requests coming from other machines on the LAN. And that approach is not what I want to do (with the notable exception of temporary setup to validate that the printer is responding to requests for printing and scanning from Linux).
Are there particular brands, makes, or models that I would have better luck in getting to work in this manner (i.e., "better stick with HP or Xerox")? Am I kidding myself that a combination printer/scanner would work in the same fashion and still be relatively easy to set up on both Linux machines without resorting to some Windows-centric approach? Result of my searching so far (I have not worked my way through all of these in detail, but plan to): References to local printer connection which is not what I want:
Setting_Up_a_Network_Printer_using_CUPS
Set up a network printer using cups
Set up a printer
The post inside Setting_Up_a_Network_Printer_using_CUPS that starts with "running an HP Photosmart 8450 as a stand-alone networked printer" (where is the permalink?) is as close as I could get, but I am concerned that the instructions given are specific to the HP Photosmart 8450, or specific to the HP vendor, versus for all printers that can be connected to an Ethernet network (not that being locked into HP is going to be a problem necessarily, but I would like to know why if that is the case). Linux compatible printers says "Have a look at LinuxPrinting for known working drivers for printers data base. Also buy from a linux friendly company, ie HP, Brother, Epsom." Later in that thread, someone said Definitely don't buy canon.
Does anybody have some thoughts about a local dns server cache size? What is the optimal one? In terms of memory consumption and number of re-enters into the cache. Lets say that default size is 150, so I've change this to 500 and after some time I see 379 re-enters into the cache. Simply put I need to increase the cache size 2 times. But due to the fact that browser preloads dns names it is not possible to interpret the number of overwrites in terms that it is not possible to say if useful cache entries were overwritten or those that the browser precached ( in other words not needed ). In this case it is ok to overwrite unwanted entries because it is not likely that I'll need these entries anyway
I'm running the dnsmasq on an embedded system with limited ram and with an umts dongle attached. It is important to keep the cache size as small as possible to reduce memory usage and at the same time to reduce number of external lookups because dns latency of the umts connection is high (1-2sec for the dns query)
I am in a VMware environment, and using RHEL 5.4. I am trying to setup a PXE Kickstart installation. For this I have configured DHCP and TFTP, made a kickstart file and shared it in the network through HTTP. My problem is that somehow kickstart file (ks.cfg) is not picked by the machine in which I am installing the OS. Although, the contents of my kickstart file can be viewed over HTTP. Please see KS_Error.jpg.
[Code]....
However, I believe DHCP and TFTP is working fine as I am getting the correct IP 192.168.1.115 which I have set in /etc/dhcpd.conf. Also, my label 1 which I have set in /tftpboot/linux-install/pxelinux.cfg/default is working fine as I able to locate initrd and vmlinuz. Please see attached Image_1.jpg how to troubleshoot this. I need to paste any of my configuration files?.
I should preface this by saying I'm pretty much new to ubuntu. I was a nerd back when I used windows, so I'm fairly knowledgeable about it, but I lost interest right before switching to linux, so I haven't learned much past basic navigation.
I bought a WPN311 wireless card for my homebuilt machine a while back and still can't seem to get it to work.

View 2 Replies View RelatedTrying to set up a LAN with an FC14 laptop, FC15 PC and a Windows machine running XP. I have SAMBA installed on both FC machines, but neither of them can see shares on each other or the XP machine. I can ping between all of them. The Windows machine sees all of the SAMBA shares.
When I attempt to Connect to Server under Places on the FC15 PC, I do not have a Windows share option to choose from as I do on the laptop, suggesting smbclient isn't configured correctly on that machine. SMB, NMB and WINBIND are installed and activated on startup on both FC machines. Although I have the Windows share option on the FC14 laptop, it will only connect with the IP address.
Firewalls and SELinux on both machines are disabled. Here are some configuration details:

I'm know very little about Linux but decided to set up a machine running Drupal CMS on a Debian machine and it won't go. The folks at Drupal have tried to help but it seems the Debian OS won't do it's PHP thing for Drupal.

I set up a ubuntu server 10.04 lts as file server in a network filled with xp, win 2003 and win 2008.
I noticed that if from any bill's SO machine i copy a file (for example a vob file of 1gb, or a lot of doc and pdf files) in the samba server, while the copy is in progress if in another windows I browse other folders shared in Samba, the copy process stops and say ' the name in the network is no more available( or something like this). It seems that samba pay attention on the fact that a user is browsing the share and doing so it seems that Samba forget that in one of its share there was a copy in progress, very annoing. A file server cannot do that, in this way is useless.
I don't understand this error nor do I know how to solve the issue that is causing the error. Anyone care to comment?

Error: Caching enabled but no local cache of //var/cache/yum/updates-newkey/filelists.sqlite.bz2 from updates-newkey
I know JohnVV. "Install a supported version of Fedora, like Fedora 11". This is on a box that has all 11 releases of Fedora installed. It's a toy and I like to play around with it.
I was laughing about klackenfus's post with the ancient RH install, and then work has me dig up an old server that has been out of use for some time. It has some proprietary binaries installed that intentionally tries to hide files to prevent copying (and we are no longer paying for support or have install binaries), so a clean install is not preferable.
Basically it has been out of commission for so long, that the apt-get upgrade DL is larger than the /var partition (apt caches to /var/cache/apt/archives).
I can upgrade the bigger packages manually until I get under the threshold, but then I learn nothing new. So I'm curious if I can redirect the cache of apt to a specified folder either on the command line or via a config setting?
