View 1 Replies View RelatedGeneral :: SSD Without TRIM Support Under Current State?
Mar 29, 2011There are not SSDs with TRIM support available in my region that fit into my laptop (1.8", IDE, ZIF). I'm running Ubuntu 10.10.
Most articles (or questions on superuser) I've come across concering TRIM (or the lack thereof) date back to 2009, when not many SSDs with TRIM support were available and OS support was still very fresh.
I'm interested in the current situation, but I couldn't find too much information about it.
What are currently the "best practices" for using an SSD without TRIM under Linux?
I've read about the wiper script included with hdparm. Do I understand correctly that I could use this to free unused blocks, e.g. by running it once a month?
Some sources state that HFS+ (the default-filesystem of Mac OS X) doesn't suffer as badly from lack of TRIM as other filesystems. How about linux filesystems? Are there filesystems that are better suited for SSDs without TRIM than others?
Fedora Networking :: Root Can Not Bind Socket On Lower Ports (<1024)?
May 9, 2010I am encountering a wierd problem in FC12. When I try to lunch a program that listens to a lower port such as 80 or any one that is less than 1024, I always get "Permission denied" error message (I am running it as root!).Then I try starting httpd service daemon that listens to 80, no errors, the daemon started and listend to 80.PS: I checked selinux, it has been disabled.Do you have any knowledge on this case? BTW, the kernel version is:2.6.31.5-127.fc12.i686.PAE #1 SMP Sat Nov 7 21:25:57 EST 2009 i686 i686 i386 GNU/Linux

Feb 1, 2011I'm simply trying to make a little restriction on www packets under two rules:
1. Allow inbound/outbound www packets (works!)
2. DROP inbound traffic to port 80 from source ports less than 1024. (DOES NOT WORK!)
Now, technically, when i use hping to test my rules, hping3 192.168.100.100 -S -p80 -s 1023 I should NOT receive any packets. However, i still receive packets, which means my rule that says less than 1024 does not work. (see below)
And this is my iptables rules in shell-script so far:
#!/bin/sh
DEFAULT_NIC=eth0
SERVER_IP="192.168.100.100"
ALLOWED_WWW_PORT=80
IPT="/sbin/iptables"

Networking :: Make P2p Work If No Ports Listening
Oct 18, 2010In emule p2p filesharing there's this thing called the id that is low if you do not configure your router for certain ports to be listening for incoming connections, forwarded by the router to ports on your pc. When the id is low, your downloads take longer or something like that. But if you have no listening port, how can a peer download from you?

View 3 Replies View RelatedUbuntu :: Processes Listening To Ports / Ipv4 | Ipv6 Only
Jul 3, 2011I'm running a native dual-stack (ipv4 & ipv6) dsl connection.So, I've been adding firewall rules, cleaning up unwanted processes, etc to tighten security.I'm left with only 3 processes that are listening to ports. mysql, ipp & ssh.Still not quite sure I need mysql. I run Amarok but without using a database, so I don't actually use sql for anything that I'm aware of.Anyway, my question is;Is it possible to make any any of these processes listen to ipv4 only or ipv6 only? Is there a distinction there at all?
Example- ssh is currently listening to port 22 on both tcp & tcp6. I do all my ssh connections using 'ssh -6', so, Can I make ssh listen to tcp6 only, or ignore tcp ?
Fedora Networking :: Tool To Create Multiple Listening Servers On TCP And UDP Ports
Jan 17, 2011Looking for a test tool where I can fire up any number of ports (TCP and / or UDP) to listen on.
I am currently getting my using nc but its only 1 port at a time (i know I can open up multiple sessions but thats cumbersome), it can't do UDP, and it closes at the end of the session.
A friend has suggested socat but it looks pretty much the same except it can do UDP, but also cumbersome, I have to manually output to a different file per port, etc.
Basically its so I can quickly test firewall and NAT rules.
Ubuntu :: Get A Recursive Listing Of All Files Under The Current Directory?

What's the correct way to use wild card pattern matching when using the -R switch? Or maybe that isn't possible?

Oct 20, 2010how to pipe the current directory listing into sort so that the output is the date in descending order (primary sort key). If there are multiple entries with the same date, I'd like the times sorted in ascending order. It seems simple but for some reason this isn't working:

For some reason it doesn't seem to ever get to the second sort key when using column 6 (last modified date).
Fedora Servers :: Virtual Machine Manager Won't Allow Memory Allocation Over 1024
Jan 26, 2010I'm running Fedora 11 (2.6.30.10-105.2.4.fc11.i686.PAE) 8 GB memory on a AMD Phenom(tm) II X4 965 Processor, 4 core server I just built.The problem I have run into is any virtual machine that has >1024 MB memory assigned to it will not boot. As along as it has 1024 MB or less it boots fine.The symptom you see is a very quick message "Booting from hard disk" the screen then goes blank, you can't login through SSH, and can't ping the network address so I know it's not some crazy video problem hiding the boot process.The attachment are messages from a failed boot attempt.

Software :: Current State Of Radeon Drivers ?
May 14, 2010Can anyone update me a little on the current styate of Radeon Drivers? I have a laptop with an RS690M video card on Slackware64 & Slamd64
There is
1. Kernel driver (drm/radeon.ko) but I am finding it difficult to find comments on it, except that it does some power management stuff
2. Proprietary fglrx had a recent significant update, and now talks to my card after a fashion (Experimental support)
3. OSS Radeonhd for X, which I gather is probably the worst atm but it's what I have in xorg.conf
4. OSS radeon driver, which is supposed to have more work done on it.
I don't need framebuffer stuff - the screen is hard enough for me to read as it is, but I do like to watch the occasional tv program or dvd and I'd like the video to be keeping up in full screen. ATM, Xvid, Opengl, and just about everything fails to, except sdl.
Slackware :: Current - Waking Up From Suspend State?
Apr 26, 2011I have a new clean install of 64bit current slackware on a machine which previously run 12.1 to 13.1. It had suspend to ram working quite reliable before, but now i get black screen (sometimes with nonresponding mouse cursor on it) at every second or third wake-up.
I found out that it is not a complete lockup - full access to kde desktop could be restored by hitting alt+sysrq+s followed by alt+sysrq+l several times. I wonder what is causing this? How to get it to wake up normally at once?
Edit: I've installed latest nvidia drivers (260.19.44) for GeForce 8500GT card - previous version (260.19.21) of drivers exhibited the same behaviour in my current install of slack.

View 2 Replies View RelatedGeneral :: How To Identify Current CPU In A Parallel Machine
Sep 1, 2010I do not know much about parallel computing, but I do have access to a few cpus.I am trying to write a program compatible for multiple cpus, but to do it, I need to ensure unique directories. I have figured out that the time of creation, process id, and cpu id form a unique combination I can use to name files (up to the degree of accuracy of the internal timer).Anyway, I am using perl. I know how to find the process id and I know I can get the time pretty easily, but as I said, I do not know much about hardware or parallel computing. All I need is a way to identify each cpu in the system and I am set for half of my program (the other half is significantly more straightforward and is mainly about text parsing.)
So anyway using terminal, perl, etc., I could access this identification? Or could someone at least tell me the name of what I am looking for? I have seen the words "ip" "MAC" "hostid" and a bunch of other "id" things come up in my googling, but I really cannot figure out which is the one relevent to me

OpenSUSE Install :: Current State Of Affairs With The UEFI/EFI Install Support On A Empty Hdd For X86_64?
Mar 21, 2010I was thinking of trying out the UEFI support that HP has in my laptop BIOS in the next few days. My reasons is that I get a custom boot logo... and (hopefully) a better boot-speed. What is the current state of affairs with the openSuSE UEFI/EFI install support on a empty hdd for x86_64 does anyone know? (badly worded I apologize) This may seem naive but I have struggled to answer this with most posts being about Mac's for obvious reasons.
Specifically, Do I have to have any custom knowledge on formatting the HDD with a GPT partitions or does the installer do this for you? Secondly, How well does the UEFI bootloader tie in with the config tools in YaST2? (I would like to have UEFI but if it turns into some headache in setting up the boot area by hand each time the kernel updates I will forget it.) I can safely say this will be a machine with only openSuSE installed as an OS, no need for any others or any dual-boot problems. This isn't overly urgent and I will dedicate (at least) a whole weekend to tweaking once I buy a new disk and install openSuSE on it. If nobody knows then I will dive in head first and report how I find it and any problems (and severity).
Networking :: Ping Between 2 Eth Ports On The Same Machine?

using tcpdump on eth2 shows ARP request received, no ARP reply being sent out
Not sure whether this config is supposed to work?
Networking :: Redirect Ports To Another Machine On Same LAN
Dec 15, 2009I have a bit of a strange scenario. I have a machine with a fixed IP (192.168.0.108), running Linux. It has an external IP 99.99.99.8 via a 1:1 NAT on a Cisco ASA/router. Port 3389 (MS RDP) is open for 99.99.99.8. I want my Linux machine to listen on port 3389 and redirect all traffic to that port to a Windows machine (192.168.0.100). In this way, my Linux box is able to respond to requests on all ports, but port 99.99.99.8:3389 connects to Remote desktop on the Windows PC. I do not have access to the Cisco NAT config. I was able to get this setup to work by using an SSH tunnel.
I ran this command on the linux box:
ssh -L 3389:192.168.0.100:3389 ergosteur@192.168.0.108
Any ideas? Perhaps using iptables or something?

Ubuntu Security :: Stopped Forwarding All Ports To Machine In Router
Mar 1, 2011This morning I was looking at the router's log file and noticed a certain IP address was able to gain LAN access on port 2222. That just happens to be the port my SSH server is listening on! A whois search revealed that IP address is in Germany. As soon as I found this out I stopped forwarding all ports to this machine in my router.
how to tell what had happened, what information this person was able to obtain, and if he left any goodies behind that could hurt me? I've read through some of the logs on my computer and haven't been able to find much at all. I did have some personal information on the hard drives, but that information is encrypted. I'm thinking if they were able to get my SSH password then that information probably isn't safe either (assuming they have some of it).
