Ubuntu :: Keyring Error Blocking VNC?

May 11, 2010

I'm trying to use VNC on my headless desktop server that's running lucid, but I can only use SSH because a pop asking me to unlock the keyring shows up every time I try to use VNC. I don't have a monitor for that desktop, so I was wondering, is there any way to remove the keyring/to automatically unlock it during autologin? I don't remember what a site I found it on, but I used this to remove my keyring yesterday. It's no longer working today.

I have a device that is working on modbus protocol andI have written a small program(with block TCP read method ) to read its registers via modbus protocol.my program is working very well but except those times that I unplug the Ethernet cable or turning off the modbus gateway during programs work.at this time my program stops on recv system call (if it reach this system call exacly when I unplug Ethernet cable or turning off the modbus gateway during programs work).I changed my source to work in nonblock TCP method, at this time with the same situation my program does not stop/block on recv system call but after pluging back the Ethernet cable or resuming the connectivity situation back it reads data incorrectly .this is my code:Quote:

#define DEBUG
#include <fcntl.h>
#include <string.h>

General :: Boot Up: "Login Keyring Failed Your Login Keyring Did Not Succeed"

Aug 4, 2010

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.

Adobe AIR could not be installed. Install either Gnome Keyring or KDE KWallet before installing Adobe AIR". I opened Kwallet and tried again, but to no avail. I am running OS11.4 64 bit.

Ubuntu Servers :: SSH Behind NAT Blocking IP Using UFW?

Mar 18, 2011

I have a SSH server on Ubuntu 10.04 running behind a NAT. I have done the port-forwarding at the router. However say for example I want to restrict people connecting to the SSH server by country IP's. When I configure ufw with the following rule it still lets the IPs that are restricted through. Any idea why

Ubuntu Security :: UFW Is Blocking Connections Even Though It's Set To Allow For In/Out

Aug 1, 2011

I might be misunderstanding the log but it looks like UFW is blocking connections. I want to allow all incoming and outgoing. I guess what I'm saying is that the servers on my computer will open ports but all other ports should respond with closed just like a default Ubuntu install. Trying to use UFW to monitor connections without really doing any firewalling.

Ubuntu Servers :: Cox Cable Blocking Port 80?

Jan 30, 2010

So first off, it probably seems this question has been asked thousands of times before. but I did do a search, mostly archived posts that ended up being something other than a true ip blocking of the port. [URL]..

So my port 80 is truly blocked. Ive tried setting up the port forwarding on my router, Ive tried manually allowing all traffic on port 80 through ip tables. Ive even dabbled with setting up something like openDNS to see So far nothing, Im only available on my local network.

There has to be some way to do a redirect though. even something as simple as an htaccess file redirecting [URL].. xxxx (the space is there to avoid my url being interrupted by a smiley

Ubuntu Security :: Denyhosts Keeps Blocking External Ip

Oct 31, 2010

I've been using Deny Hosts for a couple of years now without trouble. My router forwards SSH calls to host tock on my LAN. My router's internet hostname is michigan. I keep an svn repository on tock and access it through michigan. In this way I can update my repository when I'm at home or away.Just today, however, whenever I try any ssh to michigan, I get a closed connection and find michigan in my hosts.deny file. I delete it, make a successful connection, but then on my next attempt - there I am in the hosts.deny file again.

I've worked around it by putting michigan into my hosts.allow file, but I would really like to know what's going on. I've configured Hosts Deny to lock out IPs after three failed attempts, but it is locking out michigan after one successful connection.
