My comp is litterly doing nothing, and 61% of my RAM is being used as cache. I don't know if I created a swap space correctly. I loaded up gparted and I see that I do have a 2gb partition labled linux-swap. Why am I completely out of RAM? I have 4gb btw

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?
I installed squid cache on my ubuntu server 10.10 and it is work fine but i want to know how to make it cache all files like .exe .mp3 .avi ....etc. and the other thing i want to know is how to make my client take the files from the cache in the full speed. since am using mikrotik system to use pppoe for clients and i match it with my ubuntu squid

View 4 Replies View RelatedI'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?

Whenever I plug-in my USB 8gb pendrive to copy a large file, it takes eons. Using Ubuntu 9.10 for AMD64. At first it copies a file at high speeds, because it's not actually writing to the USB but to the cache; at 500-700mb, the write cache is full and flushes, *while* still copying the rest of the file. Since the system is trying to access the USB in two different places at the same time, the transfer speed bunks down, often to 200-300kb/s. The final process, instead of taking 2 minutes, takes one hour.
This continues until 1.4gb, when the cache finishes the flush, the copy can continue streamlined and the last 200-300mb are copied again at quicker speeds. I've made a test, copying a 1.6gb file to the USB and waiting for the cache to get full. Once it happens, I copy another file of the same size to the USB at the same time, when it starts copying I cancel the previous copy - cancelling it could take 1-2 minutes, but once it's cancelled, the second copy goes amazingly quick since the pendrive doesn't have any access troubles anymore.
However, that means for the trick to work that I can't copy four 1.6 files to the 8gb pendrive, but only three. The fourth one would need an hour unless I start copying it just before the first three finish so the write cache is still not in use or something like that. So what I would want is that everytime I plug-in this specific USB drive (identified by its label or UUID), the automount parameters disable write caching for this drive. Is that feasible? Using fstab or how?
I'm trying to convert some of my old Pidgin-logs to Empathy's format, and I've run into an issue I can't figure out. The Empathy logfiles contain a "token", which is a sha1-hash of the user's avatar at the moment the message was sent.The avatars are stored (in my case) in ~/.cache/telepathy/avatars/butterfly/msn. All filenames contain the sha1-hash, and have no extension (such as jpg/png). Some avatars uses only the hash as filename, but some has the prefix "_3" before the hash.Does anyone know why some avatars are prefixed "_3"?

A few releases ago things used to work this way, but seemingly since Jaunty it no longer does seem to work:
This used to work: I have several Ubuntu machines to upgrade and limited (and highly expensive) bandwidth available. In the past I would upgrade/update one machine and copy the contents of /var/cache/apt/archives to the other machines to be upgraded. When updating/upgrading the distro the packages that already exist in /var/cache/apt/archives would not be downloaded from the Internet while utilising the locally cached .deb files, saving time and bandwidth.
The Problem: I have noticed that since 9.10 (and with 10.04) this no longer appears to work. While the .deb packages may exist in /var/cache/apt/archives, the same packages would be downloaded from the Internet regardless of the same .deb file existing in /var/cache/apt/archives/.
Question: What is wrong and how can I restore the functionality present in copying cached packages from machine to machine in order to save bandwidth?
Why I need this to work: At work (and I have no control over this...) we are limited to a total bandwidth of 3Gb per month for multiple users. Needless to say a single upgrade of a recent Ubuntu distro can decimate a large proportion of our monthly available bandwidth. Upgrading multiple machines is absolutely out of the question if the packages have to be downloaded every time.
An apt-cache server is not an option: The option of a local apt-cache server is not feasible due to the same 3Gb bandwidth constraint. An apt-cache server requires 15Gb storage per version of Ubuntu and the downloading/upgrading of 15Gb worth of packages for that storage is not an option due to the 3Gb limitation.
My /var/cache/apt/archives directory has almost 9000 items and is over 12 GB big. All it contains is a bunch of .deb files. Do I need this file or can I delete it to save hard drive space?

Ubuntu 10.4 64-bit.I am almost certainly using the wrong term here, but if I knew for sure what I was looking for I probably would have managed to google it.In a fit of minor insanity, I used ffmpeg to convert all my video files I've impulse downloaded over the last decade or so to mp4, mostly because Easytag will happily tag them an assist in reorganizing them, but of course some videos didn't convert, either properly or at all due to issues with the original file.
But - every 108 -123 (Going by the filecount in my trash when it happens; I've wondered if the actual number is 127 or 128 but haven't gotten that definitive yet.) videos or so, totem dies, and so does every other video player I can use, VLC, mplayer, et al. For awhile I rebooted, then I figured out just logging out/in cleared the error, but I've yet to narrow down what exactly is causing it.Since it crosses all players I can only assume that there is some kind of cache that is getting filled up that is cleared when you logout, but after doing some digging it's nothing cleared by anything I've found like bitbleach.
I have ubuntu lucid lynx server running on an old eMachine as a fileserver. It has a big (2TB) slow (10-20 MB/s) external drive (ntfs-3g), and a small (20G) fast (60 MB/s) internal drive (ext3).
Using smbfs and vsftpd and sshd, all my data lives on the big drive and I'll see dramatic speed differences between the drives.
I'm wondering, is there a way to things up so that the external drive uses a cache on the internal drive to speed things up?
For example ... ftpd takes data from a client, and instead of slowly writing it directly to the external drive, it is written first (and quickly) to the internal drive, then, later, it is written to the external drive?

How do I clear the System cache memory.
For the past few days , I am facing problem in opening websites (firefox & Chrome).

Had anybody ever tried flashcache [URL] under ubuntu? My idea is to increase the throughput of a small server especially for database operations by using an SSD as cache.

a few days ago i set my FoxyProxy settings to tor. I needed it to make a few raid boards on 4chan and those can get you banned if you post.
So anyways, i go on this forum about a phone and i accidentally refreshed the page, but i haven't switched from proxy to my default settings and so all of a sudden a message appeared "Sorry, ###### you are banned from this forum."
I tried clearing cache, cookies and whatnot through firefox' options but still i get that message, i installed Midori for a quick test and it seems to work there (I'm not banned) but never on firefox, even rebooted and still nothing.
I really hate the ads with Midori as i use Adblock for firefox.
