Ubuntu :: Keyring Preventing VNC Connection After Reboot
May 13, 2010
I have a headless Jaunty server that I need to access from both mac and PC clients. If the server has been rebooted, I can SSH into it, but I can not VNC into it unless I unlock the keychain. The problem is that I can't figure out how to unlock the keychain from SSH connections, so the only available method is to attach a keyboard to the physical box and enter the keychain password at the server itself.Is there a Terminal command that I can use to unlock the keychain? I have seen references to the 'security' command but that appears to be unavailable to Jaunty?
Is there an even better method than a Terminal command? I don't want to be putting passwords into the Terminal log if I can help it. Ideally, I would connect via SSH, confirm the keychain somehow, and tunnel in through VNC.
I'm running F13 with KDE 4.4.4 on my desktop PC. A few months ago I had occasion to run Kalarm (invoked via "Kickoff" app launcher). Ever since that time, the Kalarm icon appears in my KDE "system tray" after I login. I power down my PC when I'm finished using it for the day.In an effort to get rid of the Kalarm icon, I changed my KDE "session manager" (System settings -> Advanced -> Session Manager) settings to: "on login: start with an empty session". But the Kalarm icon still appears in my "system tray" after the next reboot/login.I've also tried right-clicking on the Kalarm icon and selecting "quit". The icon still re-appears after the next reboot/login.Why didn't the session manager setting: "on login: start with an empty session" get rid of the Kalarm icon?
I am trying to Setup citrix ICA client 9 on Ubuntu 9.04 Server. I installed it very easily and I am not getting any lib error also. But when I try to connect to the citrix server, it fails with a pop up saying "Error in Network Connection Network or Dialup connection may be preventing ......" This is driving me crazy from 3 days. My project is to check the feasiblity of a Linux desktop
just did a dual boot or whatever you call it last night)and I can't figure out how to connect to my home wireless internet. I checked in one of the menus, and it says "firmware missing". Does anybody have an idea of what I need to do to fix this? If I haven't been specific enough, please ask for more information. I'm not really sure what to include.
I'm a bit puzzled by new "keyring everywhere" feature, well the case: Now I'm using 11.3 brand new suse and just when I want to connect to INTERNET via my DSL connection, a keyring password window appears, well I fill in the keyring password and hit enter, then another window pops out with my DSL connection asking me to enter a password for my DSL connection (but I've already set it up it before) and ok, I enter my password hit enter, but DSL window pops out again! and nothing happens,
I do it several times like a puppet, then I delete my DSL connection and make it again, so everything works with passwords no(no keyring is being promted). SO what do I do wrong? How can I disable this keyring feature, I do not need it at all, why do I need to recreate my connection every single time?
I am using Ubuntu Intrepid now, (no more Karmic, at least for some time)...
I connect to Internet through a proxy server. I have to configure my connection by going to Network Manager and then editing IPv4 settings, making the address selection manual instead of DHCP and then enter the static IP provided to me by the server and also the address of my gateway... Then I have to go to the Network Proxy under System --> Preferences and set my system proxy (Apply System Wide)...
Well that seems normal, except that I have to do the connection configuration part every time I reboot... Every time i reboot, the connection is back to default i.e.
Quote:
Name: Auto eth0 IPv4 Settings --> Method: Automatic(DHCP)
One of my friends reported the same thing to me after a fresh installation... So maybe that is a bug in the Network Manager of Interpid... I need to know a workaround, or a repair.
I just installed 10.10 on a desktop machine, dual boot with Win XP. Everything went well, it connected and did all the system updates etc. Then one time I rebooted and it wouldn't connect. I've tried rebooting again several times, tried unplugging the modem/router from the power and from the computer then reconnecting everything and starting it up again, no joy. I booted from the Live CD and it connects without any problem, likewise from Win XP. My Network Connections shows 'Auto eth0' and below is the ifconfig output.
Code: jim@ubuntu:~$ ifconfig -a eth0 Link encap:Ethernet HWaddr 00:13:8f:b8:ad:fc BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:42 Base address:0x6000

I'm running Ubuntu 10.04 LTS. Last night I was doing some admin on this box, it's running apache and ASSP for spam filtering. Once I finished I started some updates.I checked for updates and applied them, but fell asleep. This morning, my session had timed out at continue. I reconnected and saw a message stating a reboot was required.I've rebooted, my usual services are running, eg apache and ASSP. I can view pages on apache and the admin page for ASSP. I'm remote from the system, so connecting over the internet and when I try to connect, it fails.
Quite urgent, however at least my services are working. However I'm not happy that I can't access the system myself.I don't know if this is my own fault for leaving updates unattended or if an update caused the problem. Thanks.
I running Ubuntu ver 9.04 I have 2 problems that I think are related. After finally making a network connection I updated Ubuntu, and after a reboot I lost my network connection again.I updated the following file nm-networkmanager-settings.conf and saved it. After another reboot I then lost my network connection icon and it also does not appear under System > Preferences. I tried to then update the same file and can not save it, I get "could not save file".I have tried sudoedit, sudo gedit, gksudo gedit and some others that I cna not remember now and all give me the same result
I updated to the latest available kernel for Kubuntu 10.04 today (2.6.32-24). When the system rebooted, it refused to connect to my wireless network. So far I have been unsuccessful in persuading it to connect. ifconfig shows the existence of the ethernet connection as eth0, and Network Manager also seems to accept the existence of the ethernet port - so why has it suddenly chosen now to stop connecting to the wired network?
I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:
****Before Connect**** jake@jake-laptop:~$ sudo iwconfig eth1 [sudo] password for jake:
I can get connected to the Internet when I reboot the system, but the connection usually fails after within 10 mins. However, even then the network manager says it's connected. Never reconnect, manually or automatically.
I have been using this fresh Debian 8.2 install for 3 days without any network problems.
What I did this morning :
- Booted in my windows partition and rebooted immediately just to remove the system from the sleep state - Mounted a NTFS hard drive and copied some file to my .wine drive_c
Thats when I noticed that my connection was down.
I verified all the physical layer. My laptop has access to the internet tried to connect on an another router with eht0, changed the wire, nothing worked.
It seems like the interface can't get a dhcp ipv4 address even when I try to force is with dhclient, I get no offer when my laptop works just fine.
- Booted on my windows partition without changing any connection and my internet was working. - Booted back on debian still not working...
I rebooted my vServer (Debian 8) and it doesn't came back up. Well, I used the rescue console on my server and the server seems to be running fine, except the network was broken. So I tried 'ifconfig' but nothing came up. So I tried to enable my interface with 'ifconfig venet0 up', and now it appears in my ifconfig list
My HWaddr doesn't look that well :) 'ip addr' prints this result:
Code: Select allroot@i67svof:/var/www# ip addr 1: lo: <LOOPBACK> mtu 65536 qdisc noop state DOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: venet0: <BROADCAST,POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN
These are the last lines in /var/log/syslog:

And finally my network config in /etc/network/interfaces

I have my ubuntu box hard wired into my network. It all works fine, until I reboot my ubuntu box. After reboot, it can no longer see the network. I have it set up with a static ip. Not sure that I set it up completely correctly but it works fine...when working.. To fix the problem, I enter terminal: ifup eth0 That fixes all know problems until next reboot. What do I need to do so that it will remember settings and automatically be hooked into the network at power up?
i have configured as root mine wireless connection and the connection works out the box. When i reboot mine pc or i turn off mine pc the configured wireless connection is gone and i must make an new one. This is strange i don't know what is happening but i am several days struggling with this and now i ask this forum what is going wrong i am using Opensuse 11.2 64 bits, Sitecom 300 N Wireless PCI Adapter.
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.
I have finally gotten around to installing Ubuntu 10.4, and I really like it, but it does irk me that OpenOffice is installed by default. Is it possible to prevent OpenOffice from being installed?
This is a bit of an odd one, it's not so much about using Ubuntu but about *not* using Ubuntu. I am just setting up a new computer for my daughter. I have spent days configuring parental controls and lockdowns and such to stop her from being able to view unsuitable content, download programs I don't want, anything that can mess up the computer, etc. etc. At this age I am going to be over her shoulder 100% of the time while she works anyway, but something that occurs to me is that having set up all this control software in Windows, she could actually override the entire thing really easily by booting from a live CD, USB key or similar, she can keep a whole OS in her pocket and I'd never know. You can only watch so much of the time as they grow up.Can I prevent a computer from being capable of booting from external media without some kind of password? How would you begin to go about that?
I just want to prevent updates from certain repos, which are intended only for installation purposes. Those repos, however, also include updates for officially bundled packages, and i dont want to update them - just want to keep those as official versions.
I do not want my windows to be dragged and placed partially in two desktops. However, I have enabled Edge flipping to move window to next desktop. My problem is with partial overlap. Something which makes the windows stay completely in the desktop, but at the same time allow edge flipping.
I'm in the process of installing the usual Python/Numpy/Scipy/Matplotlib combination. I'm using the installed version of Python (2.7) on Ubuntu 11.04 but I've compiled Numpy and Scipy (and ATLAS/LAPACK etc.) from source. I now want to install matplotlib from the repositories but every time I do python-numpy is installed as a dependency of python-matplotlib. I've tried "apt-get hold python-numpy" etc. and also locking the version of each package in synaptic but both synaptic and apt-get will happily install the packages when requested, I assume because hold/lock version don't work on packages that aren't yet installed.
How can I prevent these packages being installed? Or is there a way to tell Ubuntu that I already have versions?
Since my desktop (Ubuntu 10.4.1 for now) has no need for anyone trying to ssh into it, I want to prevent ssh from starting as a service when I boot up.
If I type: sudo update-rc.d -f ssh-agent remove
in terminal, will that stop the service for all boots (until I run: sudo update-rc.d ssh-agent defaults -- in terminal)?
I've already removed (unchecked) ssh agent key from my startup applications
I have a virtualbox installation on top of CentOS, and I need fairly high security separation between host and guest traffic. The university network the box hangs off uses statically-allocated ip addresses, allocated to fixed MAC addresses (i.e. it eats any traffic with mismatched ip and MAC addresses).
Host OS: CentOS 5.3 64bit VBox: 3.0.4 Guest OS: Fedora 11 64bit Hardware: dual NIC, Intel server Bridged networking, with separate NICs for host and guest
I'm aiming for high-security separation between host and guest traffic. To do this, I would like to to run all host traffic through one NIC, H, and all guest traffic through the other, G. The host and guest have separate, statically allocated, IP addresses, IPH and IPG. The network forces these to be mapped to specific MAC addresses, MACH (the address of NIC H) and MACG (the address of NIC G).
So it's not too hard to write host firewall rules to enforce this policy. The rules just have to state that traffic coming into H must have a destination compatible with IPH, and traffic going out must have IPH as source - and vv for G and IPG. There also don't seem to be any trouble telling the guest to only use NIC G. As a result, turning off NIC G (or equivalently, firewalling it off from host traffic) crashes the network, I have to reboot it to get networking working.
But I can't figure how to tell the host (i.e. CentOS) to _only_ use NIC H for anything else except the guest. Even though we don't see any IPH traffic coming into NIC G from outside, I don't seem to be able to stop the host from starting connections on NIC G. Does anyone know any way to do this - to tell the host that it can only use IPH as its IP address unless traffic is coming from a guest process, and that it can only use address MACH and NIC H?
I've had a couple Ubuntu 8.04 servers hang hard with no terminal response.
After a given time the terminal login screen will go blank automatically. I'd like to prevent that from happening in order to hopefully catch any messages that get output to the screen before these hangs occur. Currently when the server hangs, I can mash the keyboard all I want, the screen stays blank.
I've tried 'setterm -powersave off -blank 0', but that doesn't seem to hold after logout.
I'd like to reconfigure vsftpd so that it does not start on boot (and I can enable/disable it using service vsftpd start/stop).
Though I've seen posts in the forums that stated that upstart jobs can be disabled by moving the /etc/init/job.conf file, other sites commented that the original file will be recreated on updates.
The other two suggestions were to alter the upstart script such that either the process starts on never:
Code: start on (never and filesystem and net-device-up IFACE!=lo) stop on runlevel [!2345]
So earlier today I was running out of space on my regular Windows 7 partition and I played around with extending it. I ended up somehow deleting grub and messing up my entire system. I've spent the last 2 hours looking for the answer to this and everyone has been saying to boot from a live disk and fix it that way.
Well, I've tried everything, the only way I can boot right now is via USB and it will NOT allow me to. I checked on other computers and even re-installed and formatted by external hard drive to try and get it to work and it refuses. I've changed my BIOS to boot from USB so I have no idea as to why this is happening. Also, I've tried using the "ls" command to find my partition via "ls (hdX,Y)/" and all of them come up as unknown filesystems.
I have taken much time and effort to get Mediatomb working on my new machine running Maverick Server, with GUI. Those of you who run Mediatomb know that it's pretty convoluted to get everything "just right".I have located the three Mediatomb packages in Synaptec and marked them as "lock version" in the hope that they will not be up(side)graded to a slightly different version of Mediatomb, which does not have Javascript enabled however, update manager still insists on trying to make the change to the other version .
