Jul 23, 2010I've been advised to "clear the java cache", and to do so under Windows, one would open the java control panel. Of course, I'm using OpenJDK, and not Java's java.

Ubuntu Multimedia :: How To Clear Video Cache
Aug 22, 2010Ubuntu 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.

General :: Sharing Postgresql Database

Security :: Securing My Postgresql Database ?
Jan 5, 2010I run Slackware 13.0 and I have an apache server 2.2.13 with a postgresql 8.4.1 database attached to it via php 5.3.0. Both the apache server and the postgresql database are on the same machine.
I have the apache server port 80 exposed to the WAN. It is not a fqdm, it's just a simple IP address. On my index page, a user can login with a user/password that encrypts to md5 via postgresql and takes them into the database.
Here is the vulnerability. Can't a hacker just scan port 80 and find my ip address running apache. Go to my index page, see that I accept user/password for authentication into my postgresql database. Then they could setup a script to simply inject html GET requests of random users and passwords and use those values on the php page(the one where the action link is pointing to in the form tag) that contains user login/password in php to login to my postgresql database. There's nothing stopping that. It would be a simple dictionary attack.
I checked out postgresql documentation and it suggested using ldap, kerberos, or md5 and not trust. I'm using md5 already. I currently use fail2ban for proftpd and sshd and it works great. After 6 failed user/pass attempts on either of these services, the IP gets banned via iptables for 24 hours. I love it. I was wondering if I could use that. Of course postgresql port is not exposed to the WAN which is a good thing. I know that when I put in a wrong user/pass from my index page, I get sent to a default postgresql pg_connect warning page. Perhaps I can increase the verbosity of postgresql's logger, find the phrase that it spits out when there's been a bad login and create a filter using that.
I understand that the way it is currently setup, my server is pretty secure, but where there's a will there's a way. I just feel that my postgresql database is unprotected even tho the postgresql port is not exposed to the WAN. They could just bruteforce from the apache server.

Debian Configuration :: Clear DNS Cache ?
Jan 18, 2011A 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.

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

Server :: Clear /var/cache/apt/archives On My Dedicated ?
Feb 4, 2010I 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?

View 5 Replies View RelatedUbuntu Servers :: Postgresql-8.4 Won't Boot At Startup On 9.10?
Apr 1, 2010I have just moved to rackspacecloud and created a Ubuntu 9.10 server. Moved everything over all fine (7-10 wordpress sites). Now I have a couple rails apps that need to move over and run on postgresql 8.4.
I installed postgresql via sudo apt-get as per usual. Usually at this point the postgresql server starts up and I can forget about it. But no luck. I booted it by running /etc/init.d/postgresql-8.4 start. When I run that command it boots fine, I can connect via psql no trouble.
I rebooted the machine to see what happened. After boot, apache and mysql started just fine, wp sites came up nicely no trouble. postgresql wouldn't start up.
I have tried installing from source, I have tried using different /etc/init.d/postgresql-8.4 scripts. I have no idea what to do.
I have downgraded to upstart to 0.6.3-10. I have apt-get updated, upgraded. I have Googled. I have pushed and pulled.
Usually with any linux issue in the past I have been able to find a solution on the net or work it out myself. This one stumps me to no end.
The other irritating part is that while I wait to work out this issue I am still paying for my old server running my Rails apps.
