My router has a firewall up and running as standard. I have installed Firestarter and can see a number of pings on the firewall
[code]...
Does this mean that my hardware firewall is failing in its job?
Before I go any further I must admit that I'm pretty rubbish at setting these up, so please be gentle!
Now my problem; I have a normal desktop pc (I don't want to set it up as a server) but when I check the hardness of my set up with Gibson Research Centre, it fails. It can see ports 22,23,80,443 as closed but still visible.....? I have never had this happen to me before and struggling my way through yast firewall tool, I can find no easy way of sorting this out.
I 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'm trying to build firewall on Debian with 'Firewall Builder'. But it won't let me compile and run unless one interface is set as management. There are two interfaces on my computer: 'eth0' and 'lo'
I don't want to be able to configure firewall remotely, so could I use 'lo' as 'management interface'?
Can we use iptables as firewall instead of Juniper firewall

I cannot log in except as one of the children - could this be because their logins have been used less often and less recently Everything was working well and I have not knowingly changed anything except the passwords after the problems started in order to solve what i thought was a simple mis-typing problem
I can log in as the children but their logins obviously do not have permission to do much

I am attempting to install Ubuntu 64-bit and it keeps failing. This is my first 64-bit system, and have not had problems with installing x86 Ubuntu in the past. When the full install failed, I tried installing it within Windows and that also failed. I've attached the log from that attempt in this post (had to trim it down to fit the file limit though). I don't know if these are the same errors I was getting on full install as I didn't write those errors down...I can try again and post them if needed though.

View 6 Replies View RelatedI have been FRUSTRATINGLY trying to upgrade to 10.04 because I was impressed with it, however, as I have predicted, it was a headache. In all actuality, it is WORSE than a headache. Both my desktop and laptop are now decommissioned, (I have Windows 7 on the 2nd laptop, and since Ubuntu/GRUB hasn't installed completely, it won't boot--I have to fix that TOO) leaving me to depend on an old Pentium III in the closet to download and burn CD images, which is STILL failing. Unfortunately, I have burned 9.10 on a rewritable CD, which I erased long ago. I have NO computer now, other than the old Pentium III which was sitting in a closet. I am tired and want to go to sleep, but I am the kind of person who finishes things that were started.
My problem is that I have downloaded (and burned to a CD) Ubuntu 10.04 TWICE, because it's failed to install. I thought that the ISO was corrupted, so I downloaded it and installed it AGAIN. Same thing. I tried making a Live USB Flashdrive install--same old, same old. It's 12:00 MIDNIGHT (Pacific time) and I can't bear to stay up this long like some of you young ones can. Thank goodness for caffeine
I KNEW that I shouldn't have done this, but I went ahead and proceeded to "upgrade". Well, the actual upgrade (thru Ubuntu Update tool) failed, so I decided to do a clean install. Thought that the process, from start to finish, would take 30-40 minutes, but was I wrong! I have been stuck with this issue since 7 P.M.!
Well, to cut to the chase, is anyone else having issues with burning/installing from their own CDs? This Pentium III is only running Fedora Core 6 with 512MB of memory, so it can get a download/burn job done OK. I am using the K3b burner in Fedora and no errors regarding a corrupted ISO appear. Why then, won't it install, after downloading and burning two separate ISOs?
I have created a VPN through network manager to a Windows 2003 server.
However when I try connecting it fails every time, I have tested with a windows XP client and this works so this would indicate I am doing something wrong in the network manager configuration.

extract some data off a failing drive the other day. I plugged it in, but got no response in windows or linux (partition is ntfs), but it does appear in the bios and /dev (though the hdd hung most linux liveCDs except rescue remix 9.04). I tried to analyze the drive, and found good smart data, so I figured there were just a few bad blocks in critical places. I ran spinrite against it in level 2 mode. the process crawled (40MB after 2 hours) and it updated the smart data to reflect many many reallocated sectors, putting the drive into a failing state as far as smart is concerned. so, now, in a last ditch effort I am turning to ddrescue to try to get an image of the drive. it's been running about 17 hours now, and has done several complete passes through "Splitting error areas".
here is my current output:
Code:
Disk /dev/sdb: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]....
have I done all I can? can I in good conscious declare this a lost cause? I do have an image from a prior run of ddrescue, with 826 MB of data.
edit: I resumed the task from log, and now it is reporting the err size as 9223 PB. since the drive is a 320GB, I find that a bit odd.

I installed the latest Ubuntu last night and have some issues with Unity. Firstly, when I open Deluge (which I've been using for about a year now) and click to close it, I can't seem to reopen it. Usually when I clicked the close button it didn't close Deluge, it merely moved it to the background.Secondly, when I open some programs (it has happened with Thunderbird, Compiz and the Help file), the top menu bar falls away. I don't mean it disappears in full screen (as it should), I mean it goes transparent and I can't click on it anymore after closing said software.
Finally, a little thing that is bothering me and I hope I'm not the only one: is there any way to move the new dock/panel to another side of the screen? I hate it on the left of the screen and I find it quite annoying that I can't fully customise it. For instance, the icons are way too big and I can only reduce them down to 32px using compiz. I find it fairly hard to navigate ubuntu now that I don't have direct access to all my folders and programs (yes, there is the dash, but that's actually more effort in my opinion...) I also can't add folders like my 'Downloads' folder. Is there some way of better customising Unity or some piece of software that might let me go into the finer details? I am very much an Ubuntu noob, so it would have to be something that's fairly user friendly
I'm running Xmonad and just recently it has stopped responding. None of my shortcuts are working at all. So I deleted my ~/.xmonad/xmoand.hs file, and still no luck. So I decided to log in as root and Xmonad works perfectly. Anyone know why Xmonad isn't working under my normal user? Is there a button i accidently pressed turning off the mod key?I was just browsing the web, then after I closed my browser nothing has been working, even after reboot.

I recently fixed a problem i had with Ubuntu which was the missing title bars but as soon as i enabled them on Compiz, my Desktop switcher app will not work. I've tried removing it and re-applying it but this does not solve the problem.Its there, in all its glory, but i cant click any of the other desktops it seems unresponsive when im left-clicking it but it responds and works fine showing blips of what it is or even adding or deleting rows and columns is optional.I know this happened immediatly following the compiz change so it has something to do with that and i think it might only have 1 desktop that it knows of because i can highlight desktop 4 and it still says 1, but im probably wrong.

I have 4 1.5 TB Seagate drives configured in RAID 5 via mdadm on Karmic. It seems that after a while, one drive always drops out of the array. It's a brand new drive, and after a reboot, it will come back in and rebuild just fine, so somehow I doubt the drive is actually failing. Here's a dmesg snip. The mounting that happens at the top is the mounting of the array, and as you can see, after a while, there is some kind of write failure.

I have been using Ubuntu 10.04 (32 bit) as a headless workstation, running a VNC screen. Worked perfectly for about 3 weeks, then suddenly, I lost the Drag and Drop capability, for all applications.
For example:
Dragging and dropping to move items on the desktop does not work. The item simply pops back to the original location. Dragging and dropping to move items from one folder to another does not work. Same behavior -- the item just pops back to the original location. Dragging and dropping Bookmarks in Firefox does not work. The attempted Drag and Drop is ignored. Copy and paste still works fine. The problem does NOT occur when using an attached monitor (primary display screen :0).
I suspected that the changed behavior was caused by an update (from Ubuntu Update Manager). I confirmed this with the following:
Reinstalled Ubuntu 10.04 fresh from the live cd.
Configured minimal networking and installed VNC server.
Tested Drag and drop -- works okay
Applied pending updates (116) from Ubuntu Update Manager
Tested Drag and drop -- not working

View 3 Replies View RelatedI have several NFS entries in my /etc/fstab file. Each entry generates an error during boot (from /var/log/boot.log):mount.nfs: DNS resolution failed for macpro.dpc: Name or service not known mountall: mount /mnt/BaseLines [656] terminated with status 32
This occurs even if I specify an IP address in fstab rather than a host name. I was really surprised by that. The odd thing is that by the time the system is up, not only is DNS working as expected, but the NFS shares are mounted as expected. I'd just ignore it for now, accept that it prevents Apache from starting since some of the server's files live on the NFS shares (this is a development system). It appears that the DNS resolver isn't running when the mounts are attempted and that they are attempted again later, after the resolver is running.
