I was wondering how safe is to use rdp to access my linux box. I am a little bit concerning about this issue because as I read on opensuse's web site rdp is "less" secure. The thing is that I do not know how much less is this "less"

After an update to firefox it had been failing, giving me a "session timeout" MsgBox. I have tried clearing history etc and reinstalling firefox. I have also tried different browsers with no success.
So, I have since upgraded to 9.10 and now I get "Setup Failed, Sorry" in the bottom left of the screen (where "Done" is displayed once a page has loaded)...
I am now trying a different approach. I have downloaded ncui-6.5R2.i386.rpm and unpacked it fine. I have tried running it, without success and have also run the diagnostic - I will post results below:
When I try and run ./ncsvc I get the following:
Code:
ncsvc> Failed to setuid to root. Error 1: Operation not permitted
So I did a sudo ./ncsvc , which gives:
Code:
mkdir(/root/.juniper_networks) failed: Permission denied
I am pretty sure that my password above is correct - I re-tried it and got the same message... I can definitely do, e.g., sudo apt-get update fine.
I then ran all of the tests available in ncdiag (./ncdiag -A) which gave the following info which might be useful

They are running Kubuntu. How to access their desktop from my home or office using Internet. Logically I remembered about kfrb and X11-vnc. But both of them need some approach to provide security. I'd like if someone could give me some pieces of advice on choosing the simplest and better approach:
To secure kfrb or x11-vnc is simpler or better to mount a vpn or to use an ssh tunnel? Is there any other solution? My pearents ISP use DHCP, so I think it would require some service like dyndns or similar...
My better half spilled some coffee on her 8month old macbook and it decided not to work anymore. Apple says it will cost around $800 or more to fix, we wont be paying that, Ill be finding a logic board or service somewhere online now that our warranty is shot and going that route.But before I send the macbook off anywhere I need to pull some data off the HDD. I was able to plug the HDD into my Linux box(internally, I dont have an external enclosure). I was able to mount the drive and copy the directories I wanted to the HDD on my linuxbox.
But Im unable to to access the directory from the terminal or from the file browser, I get an access denied message. Because I know the username and password for the macbook is there a way I can use that to gain access to the directories?Google got me this far, but when I googled "access locked directory ubuntu" or any variation of that with the terms linux and osx thrown in there for good measure.
What's the command to access a secure shell?

I was running a 2-partition hard drive, Windows Vista (lamentably) on one partition, and the other running Ubuntu. I began having trouble with the Vista partition, so I attempted to move as many of the files that I really wanted to keep as possible over to the Ubuntu partition, and then reformat and reinstall the Vista partition. As a result, I could no longer boot to Ubuntu, and I consistently got errors back from everything that I tried on the Vista partition.
The only way that I can now access anything on the hard drive is to insert the Ubuntu install disk, go into trial mode, then mount the partition. At long last, here is the problem: Is there anyway to possibly make the partition bootable again so that I could burn the files to a disk? From trial mode I can get to a number of the files on the mounted partition, HOWEVER, they are secured with the username and password of my user account on that partition. Is there any way that I can access the files from the trial mode by entering my username/password?

View 2 Replies View RelatedI'm an Oracle DBA and started working for my current employer about 4 months ago. This past weekend an alert re: FS space brought my attention to /var/spool/clientmqueue (full of mail re: cron jobs) and the fact that sendmail is not running on our Linux servers.I'm told that the IT security team deemed sendmail too vulnerable so we don't run it.Aside from FS filling up and missing notification of issues with crontab entries, I'm concerned that we may be missing notification of potential issues. In other Unix/Linux environments I've seen emails from the print daemon when it experienced problems with specific jobs.
Are there other Linux facilities aside from cron and lpd that use email to advise the users of possible issues? Are there ways to secure sendmail or secure alternatives to sendmail? My primary need/desire is to make sure that emails regarding issues on the server get to the appropriate users. Secondary goal would be to have the ability to use mailx to send mail out. There is No need/desire to receive mail from outside.
I'm trying to set up a secure web tunnel at home I have an Ubuntu box (desktop), a Mac, and a Windows 7 box. I use all of them for different reasons. I want to be able to route traffic from my browser through my Ubuntu box. I have done this before with proxy servers abroad, but I want to do it using ssh and my box at home so I don't have to pay for a service i.e (Secure Tunnel)etc.
I followed the instructions at http://bit.ly/hAnp6u. However, using my Win7 box, after I set the browser part per the instructions, I get no connection from the browser.
I am running Maverick (desktop edition - don't like the netbook remix) on my Acer Aspire One AO532h. I can deal with not being able to print, but not being able to get on my secure wireless network is getting to be a bother.I have AT&T DSL and am using an AT&T 2701HG-B 2Wire Wireless Gateway DSL Router Modem. If I had known that this particular 2Wire router-modem was so crappy, I'd have bought my own and tried wrestling around with that.I recently secured my wireless network and had to change the encryption from WEP to WPA so my iPad could get on it. Both my Mac desktops, the iPad, and an old Windows laptop are working fine, but not my Acer (or my XBox, for that matter). I've searched and searched for a solution and called AT&T (no Linux support :), all to no avail.
When I try to connect to my network, it goes and goes and either says that it can't connect, or shows that I'm connected, but with no signal/net capability.
however, until this morning I had only been using my wired connection with no problems but when I tried to connect to my home's WPA secured wireless network, it just would not connect. The network manager sees the network and when I click on it, a window pops up asking for authentication. I enter the passphrase, but still it will not connect. I'm using a Lenovo X61 LAPTOP (not tablet).

View 1 Replies View RelatedI am new to using wireshark and I've been browsing around the packets it a bit. I figured I'd try and use it to cut into a protocol that isn't documented, that I can find, but doesn't seem particularly secure. I tried cutting into a protocol and I turned _everything_ off, but wireshark was still picking up packets left right and centre. So I decided to stop the internet daemon and still, packets were being sent over the internet. So I decided to pick some of the IPs and do a reverse look-up. Each and every one of the IPs are of Russian origin or close.
I'm under the impression that these are unwanted packets. I've also noticed that they are sending data from the same port: 32165. Another thing I noticed while doing reverse look-ups is a lot of these IPs are hit in 'Spam & Open Relay Blocking System' and 'Project Honey Pot' which seem to be spam blockers and trackers. What I should do or what I should investigate? The reverse look-ups are only providing me with the ISP which 'owns' the IP block the IP is apart of. They are from various ISPs every time.

I have a Dell Inspiron 8600 laptop on which I recently installed Ubuntu 9.10. Most things work, but the wireless will not connect to my home wireless network (a Linksys WRT54G). (Cannot see any other WIFI antennas from here, so I don't know if it works on other networks). Ubuntu says I have an Intel PRO/Wireless 2200BG, Kernel Driver ipw2200.
When I try to look for a wireless network, Ubuntu doesn't see any. (Every other computer in the house does, Macs and PCs). I tried Connect to Hidden Wireless Network > New > and filled in the name and the WEP password that the Linksys gave me.When I select Connect to Hidden Wireless Network and select the network that I entered all the information for, the Connect button is always grayed out.

Also, in my research it appears that people that have Wireless problems often install the linux-backports to see if this fixes the issue.
I recently ubgraded to ubuntu 9.10 from 9.04, but I had the same problem there. I can see the secure connections, but when I try to connect to them, it tries to connect, works at it for about a minute, and then asks for the password again. This just started a week ago or so. I am new with ubuntu, so while I know that there are terminal outputs I should probably post, I don't know which ones.
View 5 Replies View RelatedFor a Secure Remote Desktop on Ubuntu 9.10 here is how I did it using OpenSSH, FreeNX and a router with DD-WRT v24. Pic of it in use at bottom of post, transferring a file and remote desktop at the same time.
For the purposes of this guide I will use a Desktop as the Server (Host) which is at home. The Client will be a Laptop that I can use to control the Desktop remotely. First you should already be familiar with the Terminal which is where you enter commands (anything in a "Code:" box).
In Ubuntu it is in Applications > Accessories > Terminal In Kubuntu it is usually on the lower left taskbar and is called Konsole I am using Ubuntu so you may have to make some adjustments to this guide if you are not using Ubuntu.

I have been using Ubuntu for quite a long time and I never got around fixing this particular wireless problem. I have tried Network Manager as well as Wicd. I am never able to connect to a secure network (WPA). When I use Network Manager, it just tries for a long time and gives up. As for WiCD, it again tries for a long time and finally says "Bad Password". Of course, the passkey is correct. When I connect to an unsecured network, it goes through just fine. I have a Dell Inspiron 1545 which uses a Broadcom 43xx Driver.

I'm running Ubuntu 10/4 but I also had this problem with 9/10. Does anyone know what this error message means? It appears to be an SSL problem but it's not clear to me what exactly the problem is. I do not have this problem with svn on my other office computer, nor my home computer. FYI, I'm running subversion on the Regina project.
The full error message is this:
Code:

In setting up wireless connections I have ran into an array of problems. First, when I installed the new OS on my laptop I had to get the correct drivers and firmware for it to display and connect to any connections, had no problem here connecting to a secure wireless network (WPA or WPA2). I then installed Ubuntu on my desktop and had to find the correct driver for the Netgear WNDA3100v2 USB adapter, got it all installed with the Windows Wireless Drivers tool or w/e it is. This made all the available connections come up. I tried connecting with the WPA password I was given for the network and will not connect.
I had the guy managing the network change the one I connect to, to a WEP Passphrase Shared Key thinking this would solve my issue, still nothing. And also in doing so, now my laptop will not connect to the wireless network using the Passphrase. I do not want to go back to Windows, and I will be getting rid of my Lan connection soon so i need a solution to fix this wireless connection problem.
