I have the DVD, and whenever I try to boot from the DVD it locks up the PC after selecting the default language stuff. I've run the media check on the DVD, and it passes with no problems. I am behind a firewall and for some reason the configuration is not allowing YUM to get through the firewall, but Firefox can get through (I have another post for this issue).
View 4 Replies View RelatedWhen I enable UFW Configuration, in a programme called Firewall Configuration, runs along with the System. Now, I configured it such that it can run along with the Session. Now, Ubuntu is already secure. So, is there any need for additional Firewall like this? (ufw is already present in Ubuntu, and this only Configures it). And, is it required to have it enabled always for keeping the Firefox running? (Because It may consume System Resources). Or, is there any other firewall that consumes less System resources or runs at the Background?
View 1 Replies View Relatedhow to configure my firestarter firewall. I have a website which requires the port 1935 to be open. I figured out how to open the port using firestarter. Is there anyway to make the port open only to this website, and not to every other website for security reasons of course.
View 4 Replies View RelatedI have just switched over from firestart to gufw.I have set all incoming traffic to deny and all outgoing traffic to allow.I have rules set for incoming traffic, and have only opened 1 port on my system for torrents. My router also only has the same port opened which again is for torrents.I use "Network Tools" which is included on squeeze and do a portscan of 192.168.1.100 and 127.0.0.1 I get all kinds of crazy ports coming back as opened. What is even stranger is if I do a few scans, these ports change, so one port on one scan may come up as open, then it will disappear and a different port may show as open.
Mind you none but the torrent port is forwarded in my router, I have no idea what any of these other ports are, or why they are even showing up.What the heck is going on? I dont think this is normal? Am I at any higher risk for attack?
I wonder do we need firewall for home pcs at all?I mean, fine, for servers and stuff, but I have my own laptop station. People have different position on this issue.

View 3 Replies View RelatedI've got a Shorewall (Shoreline?) firewall up and running, but it's logging to /var/log/messages. I'd much rather have it logging to another location e.g. /var/log/firewall but can't find (a clear enough) explanation on how to do this. Apparently, it varies greatly depending on the distro, the kernel, and the version of Shorewall that is running. You'd think it would be something as simple as setting a path in a config file, but apparently not. I'm running a stock Lenny kernel on the firewall machine. It comes with version 4.0.15 of Shorewall.
View 9 Replies View RelatedI think I have encountered a problem in the way that lucid handles proxy servers. I was having problems running apt-get update due to a firewall at my work. I also noted that I was getting 403 Forbidden for wget. So I went to System -> Preferences -> Network Proxy from my account (which has administrator privileges) and input the http address for the proxy server, and then clicked the button to "Apply Systemwide...".
Following that change, wget worked from my account, but whenever I tried to sudo apt-get update, I got the 403 forbidden response again, even though I could wget the same files that apt-get reported as forbidden. I figured that this was a problem with the root account, and so I typed
Code:
However, upon exiting from the root account, and trying to run sudo apt-get update again, I got the 403 forbidden code again!
So, it seems that the proxy settings are not being applied systemwide.
We are having a cluster with couple of disk servers, compute nodes and a head node. Disk server is nfs mounted on all the compute and head nodes.
The problem is that if any of the disk servers hangs, it freezes rest of the cluster too which is dangerous. Ideally, cluster should not care about the hanged server and run without any problem except files from that server is not visible.
Is there any way I could avoid the problem of freezing cluster because of one hanged server?
We have several systems (DELL-Server PowerEdgde) installed with Debian Jessie 8.4 (physical server and VM) and if the server has big Disk I/O (copy, backup with Backup Exec) the VMs freeze.

I have a Dell Latitude E6410 which I can boot from an Iomega external hard drive when I want to run Linux on it. It is a work issued Windows XP laptop and when I travel, I am more comfortable with Linux, so I created a dual boot option without touching their hardware. The external hard drive plugs in to the USB ports and the BIOS picks it up as the primary boot media, although the internal drive is still present. (That is the desired outcome).The problem is that the system periodically locks up solid and only a forced power off will get it to respond. The system seems to go into a kernel panic and fails to write anything before dying. The system completely locks up and stops responding to mouse and keyboard. It also seems to drop off the network. When I look at the logs after restarting, nothing at all shows up related to a kernel panic or anything else. To further complicate the diagnosis, on the reboots, sometimes the boot process locks up at "Starting GDM3", sometimes it doesn't, and wont for several attempts but eventually will boot to gnome. Some times it runs fine for a few hours, sometimes for only a few minutes. Can anyone recommend a way to diagnose this?I am trying to run Debian 6.0 32-bit with the defaults.

The Brother support page and utility/drivers are found here: URl....My laptop is the HP Elitebook 8540W and I am running Debian 8 using LVM, separate partitions for /home, /var, /temp, /swap, and /. I have looked at logs in /var/log. kern.log, daemon.log, messages and dmesg, but have not found any relevant info ...
I purged all drivers/packages and tried a manual install using each deb package, but ran into some permission errors, so I purged again. I also purged xsane and reinstalled it, then did a complete printer reinstall using the brother Driver Install Tool.The tool works great, full functionality for the MFC-J4420DW. But I know I can't live with the power drain, and I would really prefer to use Gimp and the xsane plugin rather than simple scan ..
So it's a beautiful day and I'll be happily using my computer when I realise that the screen is no longer showing that I'm typing or moving my mouse (or finger across a touch-pad). I can leave my computer in this frozen/crashed state for hours. My only recourse is to drain the battery or hold down the power button until the computer shuts down. The computer is a Dell Inspiron 6400 laptop/notebook. As my memory serves, it has an ATI graphics thingy. Radeon 1400, maybe. But I've had the computer for years and this behaviour has emerged only the past couple of months, with seemingly increasing frequency.
The OS is
# uname -a
Linux polaris 2.6.32-trunk-amd64 #1 SMP Sun Jan 10 22:40:40 UTC 2010 x86_64 GNU/Linux
(aka Squeeze?)
Sometimes this happens within minutes of turning the computer on and logging into Gnome. Sometimes this happens only hours after I've started using the computer (mainly just surfing the web). Sometimes it is preceded by a loud boop sound and the following if I have console open, sometimes not. So maybe that's unrelated. But that happened just now so I thought I'd throw it in.
One weird thing: Usually this happens within an hour of starting to use the computer, but one occasion I noticed I had not had the problem for several hours. On that occasion, the only thing I noticed I was doing that was also unusual: I had turned on and forgotten about a kvm virtual machine. After I shut down the vm, I had about only a minute before the freeze. I'm surprised now that it hasn't frozen since I started typing thing. Maybe I should always keep this forum open in a browser window.
I am running testing (with fluxbox) and my keyboard periodically freezes, meaning whatever I type in it doesn't respond. This lasts a few seconds (can be 2-3 or sometimes even more like 10) and one's it comes back I get all the keystrokes I was typing during the freeze. The frequency of the freezes can be like 4-5 times every hour and are very annoying. I can't seem to relate them to anything, they can occur during heavy usage but also when the box is doing absolutely nothing but waiting lazily for me to type some google search terms.
Can anybody help me track this problem down? At the moment I am using a wireless keyboard but this must be unrelated since I tested a couple of other keyboards (both wireless and wired) and the problem persists.
Has anyone successfully installed the x64 on VBox? Is there a different way to install the x64, because I don't think VBox can process this version. The few problems I have are:
1) it freezes during Auto Configuration.
2) freezes during boot initialization.
3) after reboot it keeps prompting me to complete a failed install, and doesn't matter if I accept to complete or not, I have the same problem.
4) freezes randomly executing system programs.
I run an old Toshiba Satellite M35x S114 Laptop with Debian Testing, it always runned smoothly - although it IS testing . Since the latest update to kernel 2.6.32 , the X server just freezes. The init goes all the way to gdm, and then a blank screen , no mouse pointer, no way to get out of this screen (not CTRL+ALT+BACSPACE not CTRL+ALT+F1 / F2 ... etc) just a hard reset.
I can boot to the older .30 kernel with absolutely no problem, gdm starts normally login successfull (as I am able to write this on the reffered machine and all).
Here comes the gory details:

>>> When it works with .30 kernel:
cat /var/log/Xorg.0.log

Noting that there are no more Modlines in the new Xorg.0.log
Besides, X is disabling the mouse and keyboard in the configuration.
I've run into an issue that I'm not sure how to address. I'm running Squeeze and upgraded my system this morning.
The packages upgraded were:
About 10 seconds after upgrading, the system froze completely and I had to do a hard restart. The system froze again 10 seconds after the bash login prompt was displayed (I'm not using a display manager) after reboot. The source of the problem appears to be my Realtek 8192SE wireless driver. I was able to boot the kernel in recovery mode and uninstall it, which has fixed the issue. Rebuilding the driver causes the problem again.
I suspect that something to do with the sysv and init packages affected the driver in this way, but I've no idea where to start in trying to fix this. I can't imagine this is a fault of the Realtek driver as it worked just fine up until this point.
IBM ThinkPad X61
Windows Vista Home
Wubi Ubuntu Karmic
I tried to upgrade to Lucid Linx while in Karmic Koala but the installation process froze while doing something with "memtest86+". CTRL-C got it to unfreeze and finish the installation but on a restart when I chose the Ubuntu OS it kept restarting rather than booting. I decided to start fresh.
So I booted into Vista and uninstalled Wubi Karmic Koala and proceeded to do a fresh install of Wubi Lucid Lynx. The installation, including the reboot, went smoothly. However, when the Update Manager was installing software a new screen popped up saying this:
Window Content:
[Title:] Debconf on Ubuntu
[Message:] Configuring grub-pc
[Checkbox:] Continue without installing Grub? (unchecked)
[Help button: explains consequences of not installing grub]
[Back button] (greyed out)
[Forward button]
So I leave the checkbox unchecked and click on forward. Nothing happens. All the Update Manager windows remain the same and nothing changes when I hit the Forward button. The "Applying Changes" window is stuck at "Setting up grub-pc (1.98-1ubuntu6) ...".
Can I safely force quit the Update Manager installation? Why am I getting that message about Grub? I didn't choose anything like that.
When emacs freezes doing a DNS lookup, that makes it rather hard to fix a network configuration file. Why does it need to do that?
View 8 Replies View RelatedI suspect this is an initial configuration bug. All firewall logs seem to be going to all
three files. That causes a lot of clutter in the log files, and makes it difficult to see whether there are any serious problems being logged.
I am learning to setup firewall in my home for that i have selected four system(sys1,sys2....sys4) for testing .I have configured sys2 to act as a firewall with two NIC. sys3 and sys4 are inside the firewall . sys1 is not connected to firewall for testing purpose.
the IP assignments are follows :
sys1 : ( fedora, not connected to firewall i am thinking, But i am not sure )
IP : 192.168.2.1 ,
gateway : blank
dns1 : blank
dns2 : blank
sys2 firewall ,IPTABLES )
code....
what happened is that sys1(not connected to firewall) can ssh to sys4(connected,inside firewall),since the rules are written not to ssh form sys1 to sys4..
then I came to know whatever the request I give, It directly goes as sys1 --> sys4. Not as sys1-----> sys2(firewall)---> sys4 .and the firewall is not filtering and processing anything for both inbound and outbound (i think it's my mistake some where). the requests are directly going inside without firewall.
I installed Firestarter firewall on debian Squeeze.Now i note there is a gui available in System->Administration which apparently does not need to be running all the time - its not set up to start on boot.When I boot I notice the boot message has a line saying "Starting Firestarter firewall .... failed"When I am logged in and type "/etc/init.d/firestarter status" as the Firestarter FAQs say, I get"Firestarter is running... ... (warning)"I can run the gui manually and still same message.
