When trying to connect to another Ubuntu machine running remote desktop using vinagre, I get a black screen on the client machine. Annoyed, I went upstairs to check the host machine, and it is waiting for me to authenticate my keyring. Why would the host need to authenticate for me to access it remotely?
View 1 RepliesI have a fresh install of Ubuntu 10.10 on a home server. I can connect to it using vinagre from another computer just fine. However, if I restart the server I can no longer vnc to it because I need to log in (start a gnome session). Is there a way to do this using just vinagre? Do I need to install another vnc server on my home server? The problem is that I don't want to carry a monitor from another room just so I can log in and start a gdm session if the home server gets restarted.

I have users that need to access our HTTP intranet from outside locations. Those locations will have dynamic IP addresses most of the time, so I can't just "allow from [ip]" in my Apache proxy configuration. Originally we considered a VPN, but determined that a VPN will be overkill to access just an internal website, since we do not want external users to have permission to the rest of the network, only the website.I currently have it working over HTTPS with basic authentication against an internal LDAP server, but I want a little more security for such an important website.

I've tried Ubuntu, Arch, and most recently Fedora but the SUSE GNOME environment blows everything else away!
The only problem (so far) is that Network Manager requires you to enter your password every time you login to unlock the password keyring. I want to disable this.
I think some distros disable the prompt by using the login password to unlock the keyring, but I use auto-login (if that makes a difference).
I am using Ubuntu Studio 10.04 LTS and I am experiencing the following problem: my computer loses its Internet connection and appears to require several reboots to re-establish an Internet connection.
As suggested on a similar post relating to wireless connection loss, I supply the output of sudo lshw -C network
*-network
description: Ethernet interface
product: NetLink BCM5789 Gigabit Ethernet PCI Express
vendor: Broadcom Corporation
[Code].....
Note that I have REMOVED my wireless card in case there was some kind of hardware conflict or failure. I am using a wired connection through a Linksys WRT54G router that is supplying an Internet connection to another computer and an IP phone without any problem.
When I run the command network-admin (or select System > Administration > Network) I can see only 3 tabs (General, DNS and Hosts) It seems that the Connections tab has disappeared (and I believe this happened when I upgraded from Ubuntu 9/Karmic Koala). If I click Help it shows me that there should be 4 tabs, not 3.
The connection dropping began prior to my decision to upgrade. In fact it took several attempts to complete the upgrade. Should I attempt to re-install the upgrade? I am not sure how to do it without losing my connection. When I visit System > Administration > Update Manager, I am informed that my system is up to date.
I upgraded to 10.04 this morning and all seems well except when the computer boots up I'm prompted to enter my password to unlock the login keyring.
Until I do that I can't do anything else, including getting a screengrab of the prompt, hence the attachment was taken with my mobile phone.
I didn't have to do this in 9.10 and don't remember changing anything to stop this.
My computer is set to login automatically so I don't really want the bother of entering my password (I know, I know, security, etc etc).
I've just started using the amazingly useful Ubuntu One, but I can't sync files from my computer, due to the pesky locked keyring, default, which wishes to be unlocked. Unfortunately, I have no idea what the password for the default keyring is. Is there any way I could find this out? I've included a screenshot, just in case.
View 5 Replies View RelatedThis isn't an Ubuntu question as much as it is a general Linux question, but is there a text based Linux emulator (preferably BASH) similar to DOSBox?See, I need GAS, Gnu Linker, gdb... pretty much everything in binutils, as well as a platform to test my programs at school, which runs Windows. I've tried VirtualBox, VMware and QEmu; QEmu is a b**** to access any files outside of the VM, VMware is hard to get portable, and all 3 require administrator access. I've also tried CoLinux, which requires admin access, and PortableUbuntuRemix, which gives me some unnecessary GUI and slows the computer down

View 5 Replies View RelatedI've got a computer i'm trying to VNC to.
The problem is that when the computer starts up/reboots it doesn't "Unlock the system keyring"(I think that's what it said).
When I try and attempt to connect to the computer it asks for the VNC password(as per normal) but fails to connect after that.
The reason is that the Ubuntu computer prompts for the user's password to unlock the system(locally).
What I want is to be able to turn on the computer without having to worry about entering the password. I've had it running fine on 8.04 yet the newer version seems to be annoying :s
The system is set to automatically login on startup too.
I've tried this: "delete the keyring folder under /home/XXXX/.gnome2" then setup remote desktop again. But that hasn't worked either. I still have to enter the password to a keyring
I am asked for my password four times when starting Ubuntu.

View 4 Replies View RelatedI have 3 computers on a local home network. Computer 1 is not receiving incoming anything from other computers on the network, and I don't know why. The regular internet works fine. Computer 1 can ping and ssh into either 2 or 3. 2 can ping and ssh into 3 and vice versa. But nothing can ping OR ssh into 1. Trying to do so says "no route to host". All computers are running Ubuntu Karmic. I don't even know where to start figuring out what's causing this, but it's probably something simple. I'm using the IPs I found listed in my wireless router's web-based control panel.
View 9 Replies View RelatedI'm very new to Ubuntu and installed it (10.10) just a few days ago on a laptop I got for my girlfriend. The problem is that she wanted me to change the username and computer name that I have set up when installing, which I tried to do. I followed the instructions on this link to change the computer name/hostname: [URL]. Obviously I did something terribly wrong, because after trying to restart my computer I couldn't boot it. It freezes immediately after the BIOS screen - just displays a blinking dash in the top left corner. The same thing happens when i try to boot from a CD (I tried both Ubuntu and Windows 7 CD's. Resetting BIOS to default also did nothing.

And it works just great when I first create the tunnel using:Quote:ssh -L 5902:10.0.0.250:5902 jk@10.0.0.250and then open localhost::5902 in vinagre (if I input localhost:2 it auto chnges to localhost::5902 for some reason).I would however like to have one less window (gnome-terminal) open and use the "Use host _ as SSH tunnel" in vinagre.But for the life of me I can't get it to work. Anyone here that can help me figure out what to input in vinagre to get it to work (without having gnome-terminal open in the background) ?
View 7 Replies View RelatedI have just completed a rebuild of my desktop PC Ubuntu install - switched from Lucid 64 bit to Lucid 32 bit. I connected to another PC with Vinagre (remote desktop viewer) and allowed it to save the connection as some name it created. Later after I noticed this I created a bookmark to the same PC with a name which I wanted. Now I cannot delete the original bookmark.
I have read about some bugs re. dealing with bookmarks in Vinagre. However, I have found no work arounds. Here is what I have tried:
1 - I did a complete uninstall of Vinagre and reinstalled
2 - Deleted .recently-used.xbel
The Vinagre bookmarks remained. Can someone tell me where Vinagre bookmarks are stored and perhaps how to delete one? If I cannot remove a single one I will zap all by brute force. Yes, I have everything backed up.

I'm having trouble with Webmin. I got it up and running. However, I was changing the 'listen on port' to something other than port# 10000. I made sure ufw was open to the tcp requests on my new webmin port only. UDP has been disabled. I type in my browser my ip address with the new port, and I get 'problem loading page' now. How can I see the tcp port webmin is set from a terminal on the host computer? Do I goto a webmin folder and change a .conf file?

My goal is to be able to host a small website and work on it remotely, so I isntalled ftp (vsftpd). When I tried to edit the vsftpd.conf file in Vinagre from work, I could only open it read-only, no surprise. When I tried 'sudo gedit' or 'sudo gedit /etc/vsftpd.conf' from terminal in Vinagre, I received the prompt for the password to elevate privileges (again, expected); however, after I hit Enter, nothing happens. I've tried a bunch of different things, but I can't get it to work. I can stop & start my ftp service with 'sudo service vsftpd stop/start' and it seems to work fine.

I'm asking this in the right place. I'm using Ubuntu 10.04 LTS and recently started getting a pop-up similar to the following at every boot up: Login keyring failed Your login keyring did not succeed. Enter login keyring here: That's not [exactly] what it says, but very similar. I should probably add that I have not set up any different 'user profiles' or whatever they're called, but am the only one using this PC...at least, at the present time. Again, this only started a couple of weeks ago and I don't know what I did to start it nor what to do to stop it. I guess it's not extremely painful to have to type my password in every time, but a PITA nevertheless.
View 5 Replies View RelatedI am working on a cluster for a molecular dynamics class and I have to edit my FORTRAN code (only the newest and best for me!). In order to get through to the cluster I have to ssh in. The network on which the cluster resides is behind a firewall, so I have to ssh through the firewall into the network first.
this is fine, I can login and move files and folders as needed, including sftp-ing into host 1, then into the cluster so I can transfer files from cluster to host and then host to me. This gets rather tiresome, so it would be nice to edit the files in place.
The problem is that when I access my code with emacs it launches the emacs client on Host 1, with no mouse support. I know the purists will howl about how I should be using keyboard shortcuts, but I am a chemist and not a programmer, so the mouse is very nice for me. Is there any way I can perhaps mount the cluster using sshfs so that when I open my code it launches a local instance of emacs? Sorry if this is the wrong forum, but I thought it was network related.
