Debian Configuration :: Clear DNS Cache ?

Jan 18, 2011

A friend has a website. the site has been moved to another server. I am inside of a private network.

Problem: when trying to reach his website, my browser keeps connecting to the old server which is on another continent

Windows machines have no problem with this. They connect to the new server without issues.

NOW what is hard to understand: even the PING utility is pinging the old server.

I tried these and none works:
- computer restart
- Clear private data in Iceweasel (has ntg to do with PING, but tried...)
- installed nscd and restarted the service
- modified /etc/resolv.conf to point to another nameserver than modified it back

At the same computer, if I reboot and load Windows, the browser has no problem connecting to the new server.

OpenSUSE :: How Clear Apache Cache ?

Sep 1, 2010

I'm getting a weird situation where even though I updated an image in a folder for a website in apache, it's still showing the old image. And yes, I checked it in multiple browsers and on diff. computers. (Apache is in a virtualbox OS)

Here's what I've done:
1. Checked it in firefox on the host, cleared cache, reloaded
2. Restarted apache
3. Checked it in konqueror for first time, still showing old version
4. Checked it in the actual file folder and it's correct there
5. Checked it for first time on virtual machine's OS in its firefox, and it shows the wrong/old image

Ubuntu Multimedia :: How To Clear Video Cache

Aug 22, 2010

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.

Server :: Clear /var/cache/apt/archives On My Dedicated ?

Feb 4, 2010

I have a dedicated server and I am having email issues etc (seemingly) because the /var directory is 97% full

I would like to know if it is safe to clear it and how to clear it (assuming it will not disrupt/kill server services to do so).

I have a 'Matrix' control panel so i can view the storage etc but it does not have an way of clearing the /Var directory.

I have Putty Access to root but do not know much about command line access.

I found a few threads but the information is not clear to me as there seems to be an assumption of (basic?) knowledge I don't yet have.

My linux support guru that usually does this kind of thing for me is away and not contactable and my server is grinding to a halt and unable to store/send email.

I have only a very basic understanding of command line but really need to get this sorted ASAP.

Is it possible and SAFE to delete files via FTP from the /var/cache/apt/archives?

Fedora :: Yum Clear Cache And RPM Update - Internal System Error

Debian Configuration :: Raising The APT Cache Limit?

Nov 4, 2010

When adding repositories, I ran up past the default apt cache limit of 25165824. I found a couple of sources - one that treats apt.conf.d as an individual file, and another that treated it as a folder - which my system does.

Following those guidelines, I went into /etc/apt/apt.conf.d/debconf70 to add a line of code that sets the default to 2x and 4x that limit, and... well, apt doesn't seem to recognize the difference.

Here's the code I added at the end:

So, is there somewhere else that I need to change things? Am I completely off on this? I found a year-old thread on this error in the ubuntu forums, where a gentleman who is now a member of the staff simply suggested to the op "take out that debian repository you listed". It kinda negated the premise for me, you know? I'm kinda hoping there's more that I can do.

Debian Configuration :: Trying To Set Up SSD As Cache Drive To External HDD With Bcache

Sep 22, 2015

I'm trying to set up an SSD as a cache to my external HDD (which is where my installation of Debian testing/stretch is installed). My installation is using LVM 2. I'm trying to have the SSD cache the entire external HDD, and not just one of the partitions (such as the root or home partitions).

Ubuntu :: Cache Hardware Configuration For Faster Boot?

Nov 10, 2010

I am using Ubuntu Maverick on my Eeepc 701, and everything is working quite nicely. Since I only have 4GB SSD drive, my setup is that the LiveCD is booted from the SSD, while my 'casper-rw' partition is on a 4GB SD card. I have 2GB of ram and do not use swap. I am wondering if there is a way to somehow cache the results of the hardware probe and configuration, and insert the cache into LiveCD by remastering it. The idea is that less time will be needed to boot, since everything that was found from the first boot was saved.

Of course this would mean that particular modified LiveCD wouldn't reliably boot on anything other than my system (or one like it), but seeing as how my hardware won't change in the future, it isn't a problem.

Is something like this possible? I'm not afraid of recompiling a kernel or rebuilding an initramfs if needed. A possible alternative idea to accomplish this would be to boot up the vanilla LiveCD as normal, configure a swapfile, hibernate, then inject this swapfile into the LiveCD image.

This way, every boot would automatically just be resuming from hibernation. This could potientally mess with the casper-rw partition, but that is something I would worry about later (and I am not opposed to just eliminating the casper-rw partition altogether and running off ram each boot).

The other problem might be that the swapfile would probably need to be the size of my ram (2GB). Chances are, after a fresh boot my ram will be mostly empty, therefore would it be possible to compress the swapfile (like swapfile.gz)? I will be looking into either alternative, but I was hoping to get some opinions / ideas on how to accomplish this (or whether it has already been done!)

Software :: Redirecting APT Cache - Can Redirect Cache Of Apt To A Specified Folder Either On Command Line Or Via A Config Setting?

Jan 5, 2011

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?

Debian :: Clear 3G Works, 4G And Con. Manager?

Jan 24, 2011

I have a Clear 4G+ Mobile USB modem. It is a Sierra Wireless Air Card 250u. I was able to get a brief 3G connection out of the box, with Squeeze 6.0. I would be happy to at least get connection manager working, as it does in Windows XP.

Subsequent edit. I did a clean install of 6.0 Squeeze, and Clear USB modum worked right out of the box. All I had to do was, right click on Network Manager icon on upper right corner of screen, checked enable mobile broadband. clicked on edit connection info. There I manually entered Clear as my provider, checked on connect auto, and left other fields blank or default settings. I still only get 3G, but I have multiple barriers to a microwave signal in my location. But I still will continue and may need help as I configure Clears Connection Manager, and or firmware.
