I have fresh and clean install of Ubuntu 16.04.1 server edition. I have set static IP address. I can ping any domain. I can connect to it via SSH. Basically IP configuration is as it was on old Ubuntu 14. But apt-get doesn't work.
It's 0% [Connecting to gb.archive.ubuntu.com (2001:67c:1560:8001::14)] [Connecting to security.ubuntu.com (2001:67c:1560:8001::11)]
I can ping domains it's trying to connect to gb.archive.ubuntu.com and security.ubuntu.com.
This is the most similar question I've found but this and answers to other questions doesn't resolve the issue.
I don't vahe any iptables rules as this is fresh and clean install.
After 5 hours spent on trying different solutions, different internet connections I'm running out of ideas.
Any help appreciated.
Thanks.
Thanks Rodney. Your comment directed me to find the solution. It's about IPv6. Just needed to disable it. Answer found here.

I am trying to install metasploit on crentos 6.6 server

then after alot of search i found that it is a problem in the DNS so i tried to edit /etc/resolv.conf
and add 8.8.8.8 as name server it worked fine but after server reboot or even eth0 restart it keeps returning without the modifications i made
this is my /etc/resolv.conf content
# No nameservers found; try putting DNS servers into your
# ifcfg files in /etc/sysconfig/network-scripts like so:
# DNS1=xxx.xxx.xxx.xxx
# DNS2=xxx.xxx.xxx.xxx
# DOMAIN=lab.foo.com bar.foo.com
is there any solution for this problem
I remember I got similar errors with CentOS.
Problem was: No internet connection.
First check a network connection:
#ping google.com
If there is no connection. You have to debug this first.
You are getting your networking configuration from DHCP but your DHCP server is failing to give you any DNS server addresses.
Did you try doing what that file tells you to do? Because that will "fix" your problem for you (assuming you don't choose to get your DHCP server fixed to provide you with DNS servers correctly).
Check location /etc/yum.repos.d/mongodb-org-3.2.repo
Delete all the irrelevent repositories in that location but be careful at that. Ex:- delete datastax repo which may be present
Run yum clean all
Run yum update
I installed VirtualBox on Windows 7, and created a virtual machine, where I installed CentOS 7. Then in CentOS 7 I installed CollabNet Subversion Edge, following this information as a guide and
performed all the steps provided there, but I can not access the server.
The installation should be performed on a desktop machine and the server I'm trying to access from a notebook, which is connected to the same network as the desktop machine. Also obviously, as the network has a proxy to surf, I had to configure it, and doing well because I can surf the internet and others. It's using 'Bridged Adapter' networking in the VM settings.
Can you think of any idea why I do not have access? Any help is welcome.
I found a response similar to what I'm looking for, but do not quite understand what it says. I'm only in CentOS7 enp0s3 interface, and there is collabnet running, not running on another interface.
NEWS:Gain access the server using its IP (172.x.x.x:3343/svn or 172.x.x.x:18080/svn), but not by name. Maybe there is a problem in the computer name, applies only to Windows, and CentOS running on the virtual machine, use another computer name. Can it be? If so, you know how to identify such equipment?
Looks like a firewall issue. Try to run following commands:
firewall-cmd --permanent --zone=public --add-port=<dst_port>/tcp
firewall-cmd --reload
Hope this helps
I have a Pi that runs hostapd and dhcpd on arch linux to create it's own land with the Pi's (routers) IP being 10.0.0.1. This uses the wlan0 interface and it only serves as a standalone router running a web server.
Once I connect to the Pi, I use 10.0.0.1 to display the web pages, but I want to use a hostname such as firepi. I have tried using dnsmasq, but I haven't been successful. Any help would be greatly appreciated especially if you can give me some detailed examples as I am a novice.
The purpose of this system is that I have created a web app that you can use to ignite fireworks over WiFi at a safe distance. I would just like the convenience of using a hostname instead of the IP address.
I must add that I will more than likely be using an iPhone to connect to the server, should this affect anything.
Not too sure how or why but this is what I did and it is successfully working now, so this is just for future users who may need a similar setup to mine.
First I installed hostapd and dhcpd and made sure they were working. Next I changed '/etc/hostname' to firepi and the '/etc/hosts' and added '10.0.0.1 firepi'. Then I installed dnsmasq, and set the interface to wlan0, and finally added '10.0.0.1 firepi' to '/etc/resolv.conf'.
After a full reboot, I joined the network on my iPhone, navigated to firepi and sure enough, it worked!
Thanks to the other users for their advice and tips.
You can use avahi on Arch as well to resolve your hostname:
sudo pacman -S avahi nss-mdns
Start the avahi daemon:
sudo systemctl enable avahi-daemon.service
sudo systemctl start avahi-daemon.service
Edit /etc/nsswitch.conf
sudo vim /etc/nsswitch.conf
Change the line:
hosts: files myhostname dns
to
hosts: files myhostname mdns_minimal [NOTFOUND=return] dns
Reboot
Note: don't forget to add .local to your hostname.

If you just want to be able to use "firepi" as hostname to connect to it, you can simply add it to your /etc/hosts file using the syntax "IP host".
To make it as easy as possible, run this command as root:
echo "10.0.0.1 firepi" >> /etc/hosts
That'll do the trick.
Can you try avahi ?
sudo apt-get install avahi-daemon and
sudo apt-get install avahi-browse
I've successfully used that on Raspian. Unless you change the hostname using
sudo raspi-config you will access via raspberrypi.local
Note that if you plan to access the RPi from Windows you will need to install Bonjour Service first(if you have iTunes intalled, you might have those, run services.msc and check if the Bonjour Service is started)
Another note: On a friend's iphone I've installed a generic vnc client and had x11vnc running on the RPi and succesfully managed to connect to the RPi (since avahi-daemon was installed)
I am trying to install CDR-STATS on Exiting CentOS 6.4 server where FreeSWITCH is already running well, i read all available documentation and mailing list but i didn;t find any notes where can i install step by step.
Please any one know help me to get ride on it.
I appreciate your support.
Thanks in Advance.
CDR-Stats comes with a script install-all-cdr-stats-freeswitch.sh which will install FreeSWITCH with CDR-Stats. In the scenario where you have already FreeSWITCH installed, you can execute the install-cdr-stats.sh, it will prompt you with a question to know if you want to run an installation for FreeSWITCH or Asterisk.
cd /usr/src/ ; wget --no-check-certificate https://raw.github.com/Star2Billing/cdr-stats/master/install/install-cdr-stats.sh -O install-cdr-stats.sh ; bash install-cdr-stats.sh
I will also advice you to read carefully the install-freeswitch script, cause it does few things apart installing FreeSWITCH for instance configuring it to be used with mongodb_cdr.

I just installed CentOS 6.3 on a new computer and am unable to SSH to it from our computer running Fedora 16. They are both on the same network.
Some facts:
- I can ping it from the Fedora machine.
- I can SSH to the CentOS computer to itself on the CentOS computer.
- I have looked into hosts allow and deny, I have set selinux to be permissive, I tried with iptables disabled on the Fedora computer
I am fresh out of ideas...
Thanks
Do you have fail2ban running?
Do you have denyhosts running?
Do you have iptables allowing TCP 22?
Do you have a line in your sshd_config that refers to "AllowUsers"? (most dont but some do, and if yours does, you need your account listed on that line)
Can you run this command tail -f /var/log/secure on that machine at the same time while trying to login from the second machine and spot the issue? If not, paste the output from that log here for me to comment on.
A long shot, but you might try service sshd restart and try again to see if that helps. Go ahead and run tail /varlog/messages while restarting that daemon to see if you spot anything unusual while doing that. If you spot the issue great, if you dont, post the output here for me to comment on.
Last, do this cp /etc/ssh/sshd_config /etc/ssh/sshd_config.back and then take a good known working sshd_config from another machine and place it over the top of yours and then restart the daemon again & try again.
My money is on seeing something that helps us in /var/log/secure.
