Testing Tails Distro For The First Time And Unable To Connect To The Internet With It

Hello,
I am trying out a GNU-plus-Linux distribution called "Tails" for the first time. Tails is the distro that provides anonymity for the user by forcing all network traffic to go through the Tor network system. I am testing out Tails version 1.4.
Tails is a live DVD disc. It boots in live mode directly from the DVD and optical drive.
However, once I was booted into the desktop for the first time, it seems to not have been able to automatically find and configure my internet connection.
When I hover the pointer over the twin PC's icon in the system tray at the top right hand corner it says "No network connection".
Then, just to make sure, I opened the "Tor browser" and it gave me an error message that says "The proxy server is refusing connections".
Then to make triple sure, I opened the "Unsafe web browser" and it gave me the error message that says "Error No DNS server was obtained through DHCP or manualy configured in Network Manager".
So as a new user of this distro, I'm not sure on where to go and what to do. So any help would be greatly appreciated.
Thank you

Can't Connect To MintUpdate

I'm using Linux Mint 16 "petra" and normally I can see in the task bar whether or not there are software updates available or not. For the past week or so, I have not been able to get any connection to the mintUpdate site and the icon in the task bar shows a red X on the shield.

When I right-click on the icon and select "Information" I get the message below.

<<
++ Launching mintUpdate in user mode
++ Testing initial connection
-- No connection found (tried to ping google.com) - sleeping for 30 seconds
++ Starting refresh
++ Auto-refresh timer is going to sleep for 15 minutes, 0 hours and 0 days
-- Error in checkAPT.py, could not refresh the list of packages
>>

Can anybody out there inform me what may be wrong with either my system or with the mintUpdate site? I'm able to connect to the Internet without any problem.

Thanks in advance for your reaction!

Telnet / Postfix Connection Refused Question For CENTOS 6.4

Good Morning! I am supporting the coffee and Doritos industry with my frustration with this problem. I have been battling it for two months. I have several Red Hat books, the official Red Hat study guide, and have searched the forums for weeks with no avail. I was wondering if you have ever had this?

I am trying to "telnet server.example.com 25" or telnet in general. Both servers are running on a KVM on the 192.168.122.0/24 network.


[root@server ~]# telnet server.example.com
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
Trying 192.168.122.191...
telnet: connect to address 192.168.122.191: Connection refused

I can ssh, run NFS, and also run internal postfix e-mails.

IPTABLES IS TURNED OFF ON BOTH CLIENTS

Postfix and Telnet is configured on both clients, with both listening:

[root@server ~]# netstat -tulpn |grep :25
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN 1802/

When I Telnet from client named 'Server' to client named 'ISCSI', tpcdump on client 'ISCSI' gives the following:

19:01:23.579330 STP 802.1d, Config, Flags [none], bridge-id 8000.52:54:00:2e:85:0e.8003, length 43

FileZilla Connection Issues

Hello,

I am having issues connecting to my linux box (opensuse 11.3) from my Window 7 sytem. I am using FileZilla. When I attempt to connect I get this error message

Status: Connecting to 192.168.198.205...
Response: fzSftp started
Command: open "Mike@192.168.198.205" 22
Command: Trust new Hostkey: Once
Command: Pass: *********
Error: Authentication failed.
Error: Critical error
Error: Could not connect to server

I am thinking it is a setup on issue on my Linux box but not sure what to change at this point. I must have some settings correct, because I am able to remote into my Linux box using FreeNX. Any help would be appreciated

No Wireless Connection

I have installed Linux Mint 17.1 Qiana Cinnamon on to a Compaq Presario R3000 and cannot use the wireless connection. I am totally lost. I can get the wired connection, but the wireless is not there. I have tried to establish the connection, but I do not understand the lingo like BSSID of my router. I have entered the MAC address but do not know how to clone it. Help!

CentOS 6 - Connection Reset By Peer Error

Hi,

I have a CentOS 6 machine [Machine X], which I connect to using a putty client or from another CentOS 6 machine.

Now, the machine X intermittently sends a connection reset message to all SSH sessions -

Code:
Read from remote host 1.1.1.1: Connection reset by peer
Connection to 1.1.1.1 closed.

I have switched off the firewall on the machine & there are no session timeout values set.

How do I find out what is causing this issue?


Thanks

Xlib: Connection To ":0.0" Refused By Server Xlib: No Protocol Specified

hi all,
I'm new here.
I have similar problem with running a C project that uses GLUT/OpenGL graphics...


every run result with the two lines:

Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

sometimes the graphics works ok sometimes there is an infinite loop, but every execution result with the two lines above.

what is the meaning of these 2 lines?
Is it an Error or Warning?
How can I fix the code?

My guess is that there is a fundamental problem with the graphics Glut Library...Or that I didn't write the MakeFile OK

Please help me, I would extremly appriciate it.
