I found that one of my computers was issuing a DNS request to a domain on my local network every time I send a query. I've look around and saw several programs you could install for DNS local cache, but does it not come with some application by default? If it matters, I'm running Ubuntu 11.04 with DHCPD and Bind9.Also, I did add nameserver 127.0.0.1 to /etc/resolv.conf, and it's listed before my other nameservers.

I don't understand this error nor do I know how to solve the issue that is causing the error. Anyone care to comment?

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 have a desktop and laptop at home, both running the same flavour of Debian Testing. How can I configure apt on the laptop so that it first tries to download the packages from the desktop before going to the Internet?

Taking with them 2 years of my Clans Forum posts. I was wondering if maybe Firefox or Chrome keep some sort of local Cache on the HD that i can try and salvage as much data as possible from.
how should i remove a package in a local cache? i tried removepkg packagename.txz and itdeleted its files. but then i tried to install it back, it says its in the local cache so it didn't download the package but instead it installs it right directly. i want it to downloadit once again because the package isn't working.
View 3 Replies View RelatedDoes 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 had the idea to cache writes to my nfs filesystem on my local hard drive.
It seems CacheFS exists to cache reads, but not writes to nfs.
I would imagine that if I could cache writes to my nfs on a local drive I could have a fast system, but keep all my files where I want them on my network.
I'm thinking about this because I am planning on buying a SSD, and I would imagine if I could set things up this way the system could be lightening fast while keeping things on the network. Currently if I copy a large file (hundreds of MB) it is quite slow, with an SSD and caching, I would imagine the copy could be very fast.
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?

View 2 Replies View RelatedOne of Konqueror's unique features is that i can name a local process as the action in a form. When i submit that form, the local process is executed. Very helpful for certain offline tasks. What would make it even better is if i could find a way to pass some data to that local process from the html page. This could be the content of a hidden input item, etc. Alternatively, if there is a way for Konqueror to create or update a local file with data from the html page, that would acheive the same end.
View 1 Replies View RelatedI'd like a way to see all of the devices on my local network and what their local IP address is. I recall that I used wireshark to troubleshoot a similar problem a while back, but it doesn't seem to have a way to see all of the devices- only the traffic. (I'd like to do this without having to physically interface with my router if possible, and I am in an encrypted network if that matters)
View 6 Replies View RelatedI have installed a web server on my local network. Everything is well configured and web pages are shown correctly from Internet (outside the local network) using the domain or the public IP.The issue is if I try to see that web pages (using the domain or the public IP) from inside the local network. In that case the router config page (192.168.1.1) is shown instead of the web pages.From inside the local network I'm only able to see the web pages using the internal IP address (192.168.1.XX).

I don't know if it would be safe to force install without the dependencies (even though I would install them later).
View 4 Replies View RelatedI've got an Ubuntu server hosting our websites and other various things here in our own home. We recently switched to a router that doesn't support loopback (abomination), so I've set up hosts files on our computers so we can access our own sites when on our home LAN.
However, we often take our laptops as we travel about, and I'm guessing due to the hosts files when we try to access our sites, it'll look on whatever local network we're connected to for our server, which won't work, obviously.
Is there a way to set up something like a hosts file that'll only try to look up the local IP of the server when we're on a specific network (our home one), or have one that tries to look for the local IP first, then proceeds to try and resolve the domain name and use the external IP if the local IP doesn't work?
I have a Dell PowerEdge 1650 server with 3 NICs in it. I am trying to use one NIC (eth0) to connect to the internet, the second NIC (eth1) to share the internet connection to a LAN, and the third NIC (eth2) to connect to the LAN.
It is running Ubuntu server 8.10
The problem that I'm having is that NetworkManager (version 0.7.0) keeps setting eth2 as the default connection, and then I don't get any internet at all from the server.
My main goal is to be able to share files from the server to computers on the LAN. The secondary goal is to have a virtual machine hosting a Halo server, connected through eth2, so that it can host LAN games. But that is a secondary goal after I get the connections to work.
I've been looking around and finding other people who have done bits and pieces of this, but not the whole thing. I had been hoping to simply use the NetworkManger, but I don't mind editing config files.
Also I can't seem to find any good instructions on editing the /etc/network/interfaces file. The man file is incomplete, and everything seems to point back to the man file.
What is the minimum configuration to postfix that I need to do (i.e. to its main.cf file) in order to have the following:mail go from user1 on comp1 to user2 on comp2 on same landemonstration:

I've been troubled by the high amount of RAM that is used by my Ubuntu desktop. Before I installed Ubuntu 10.04 (desktop, 64-bit) my system used around 500MB of RAM when no applications were open (just cold boot into the GNOME under 9.10). But when I installed Lucid, I've noticed that my used memory is now reported as 1GB or more as soon as I log into the system.
I want to figure out what is using all the extra RAM but I can't seems to find the culprit. I looked at all of the processes and numbers just don't add up. I exported the list of processes into a file and summed up the memory used by every process in a spreadsheet. The total came to around 700MB. Yet, both System Monitor and "free" reported the time that system was using over 1GB of memory. This means that at least 300MB of RAM are used but not by any process, at least as reported by "ps".
I was wondering if there is a way to know which files are in the linux page cache. I've searched but the only thing I've found is meminfo.Is there anything out there that can give more details regarding what is being cached?

I suspect that the O/S may be caching the files stored in /tmp and /ramdisk and thus is not efficient. How can I check if the O/S is caching ramdisk files and if this is the case how can I prevent it? Is there an option to say 'dont cache /tmp' ?
Running Ubuntu 9.10. In the Remote Desktop config dialog I get: "Your desktop is only reachable over the local network. Others can access your computer using the address 127.0.0.1 or tabatha.local." I understand this means only the loopback ip address is available. All my other machines show their true local ip address (e.g., 192.168.1.104) in this dialog. Thus I cannot log on to this desktop from other machines.
When I try to do a remote logon from another Ubuntu 9.10 box (or from an XP box using a VNC viewer), I get: "Connection to 192.168.1.102 has been closed." What steps are needed to make this machine show its actual ip address? All file sharing between the various machines is working properly and all windows shares back and forth between XP and 'nix, and among the the vaious XP boxes and linux boxes are available as designed.
