Ubuntu Networking :: Use A Dyndns Hostname To Connect To Server
Apr 9, 2010
I've recently set up an Ubuntu server and from within the network I can do several things like: log in via SSH, transfer files via FTP, and remotely control Torrents from other computers. My end goal is to be able to access these services by using my dyndns hostname (example.dyndns.org)from an external network.
When I type my dyndns name in my web browser it opens up my router page. How would I set things up so that I can just type my dyndns hostname to point directly to my server, instead of the router page?
All computers are connected to a router which is connected to an ADSL modem, with automatically assigned I.P addresses.

As the title suggest, I have downlaoded the latest copy of Ubuntu Server from the ubuntu website.Everything installed fine. DHCP configured ok as far as I can tell. I can ping other machines on my network (which are running Windows) and they can ping the Ubuntu machine and conenct to Apache which is running on it.If I try to ping google.com or any other domain, it gives the correct IP address but gives no response to any pings, dont telnet on port 80 (or any toher potr for that matter) on any machine on the internet. I checked the settings using ifconfig to see what DHCP had assigned, and they matched the windows machines configuration (other than the IP address obvisouly). I tried assigning a static IP, even reserving a particular IP for my NIC.
Whatever I do, i cant connect to any machine outside the network via IP or domain.I have searched everywhere and tried everything i can find on the net but still to no avail.The Windows machines are part of a domain called alcom-uk.local and run off of a Windows Small Business 2003 Server. Not sure if i need to manually setup Ubuntu to connect using a domain or anything.

Here is what I am trying to do. I set up a Samba server on Ubuntu 10.10, which seems to be working (sort of).
I set it up using Webmin, which has always worked for me before.
I set up two shares, both of which are read/write and are allowing any hosts. And are set up using the default samba configuration that is provided by Webmin.
For privacy reasons I won't disclose the domains, but I will call them test.abc.com and xyz.com
I set up /media/mount as a share called [mount_a] and I also set up /media/mount_b as [mount_b]
The server's host name in my internal network is mount-box
I originally mapped it to a sub-domain of my domain abc.com via DNS, so that test.abc.com resolves to the IP address of my router; which has all the necesarry port forwarding set up.
In windows explorer in the remote location I tested it by using \test.abc.compoonani_a, this works fine and after a password prompt I can access my files. However, I do not want to use this domain name for this server, so I registered a new domain name and again via DNS mapped domain xyz.com to the IP address of my router.
Since setting up the new hostname, I cannot connect to it via Windows to access the samba share. It just won't work. When I try to connect the password prompt appears and I put in my credentials, when I submit it the window re-appears and it has appended the servername xyz.com before the username, so it reads \xyz.com<myusername>, but won't let me connect.
If I try again with the previous hostname test.abc.com, it works fine.
What am I doing wrong that it would let me connect with one hostname, and not another.

At school can connect to my computer via SMB/Samba and VNC from the Windows Machines, but not by hostname (I still cannot VNC in at home on my desktop computer and have yet to try Samba there because I wanna setup Samba there from the comfort of my laptop and therefore need VNC first). How come I cannot access this machine by it's hostname?

Cannot connect to internet via Firefox or Midori on my Dell Inspiron 8200 laptop with a Netgear wireless card. However, I can update via yum, I can ping google from the CLI, I can ssh to my desktop, I can point a browser to find my router which /etc/resolv.conf points to, but can't get a browser to resolve hostname. I'm posting from a different machine (desktop), here is my /etc/resolv.conf:

I have a network of 2 WinXP machines and one linux box. I have fiddled around with the settings as you do when learning. The network is working. The network neighbourhood on the WinXP machines recognise the linux box and vice versa, (the linux Places|Network recognises the 2 WinXP). I can Ping the linux box using its hostname from a WinXp. But I cannot do the reverse. I get an 'unknown host' response. I can ping the linux to itself using its hostname.

I'm trying to ping another Ubuntu computer on my local network. If I try doing,ping <hostname>then I get the messageping: unknown host <hostname>however, if I doping <hostname>.localthen I get a response back. I was wondering how I can change it so that I can ping without having to append .localI've installed winbind and modified my /etc/nsswitch.conf file but this has made no difference.

I have an ubuntu 10.04 server with hostname "abc.domain.com". However, due to migration, we had to change to hostname to something else, "xyz".
I have done changing /etc/hosts and /etc/hostname and run /etc/init.d/hostname start.
Checking the hostname and all shows it is now using hostsname of xyz. However, email sending out is still using old hostname. We have some scripts that will send out alerts like failed rsync or hdd space full to my email account. But I see the sender is still "root@abc.domain.com".
How do change that to xyz? I am using postfix. I have edited main.cf and restarted postfix but no go.

I'm having an issue on two Fedora Core 13 machines where I can ping others by hostname, but the hostname resolution fails whenever I use ssh/scp/vnc/etc. I can still do these things by IP address, just not by hostname. RHEL5.3 machines on the same network with the same configuration do not seem to have this problem.
Here's the not-so-quick-and-dirty description of the situation:
I know that there is a virtual router at 192.168.31.1 and another at 192.168.30.1. I also know that there is another network (let's call it 90.90.90.0) and on that network lies a number of resources. By nature of this configuration, any machine on 90.90.90.0 can be accessed by any 192.168.x.x, but not the other way around. Beyond that is out of my hands and currently out of my scope of knowledge.
I have a dnsmasq server on 90.90.90.10 that operates as a secondary nameserver, another machine out of my sphere of influence is the primary nameserver (90.90.90.31).
The secondary nameserver on 90.90.90.10 holds the hostnames of our development machines. The problem is that in some cases, while I can ping by hostname all day long, services such as ssh, scp, vncviewer, etc all fail to resolve the hostname. In other cases I can do all of these things.
Every machine has an equivalent resolv.conf:
As an example, I will show the output of a handful of my development machines:
I also included columbia as a one-way test -- even though it cannot access 30.x or 31.x, they can access it:
columbia -- physical machine, Red Hat Enterprise 5.3, IP 192.168.100.200
Okay, so here are the various outputs. Remember, nibbler, discovery, and atlantis can ALL:
- Ping by IP address
- Ping by hostname
- ssh, scp, vnc, etc by IP addess
Additionally, the SERVFAIL reply from 90.90.90.31 is expected since my dnsmasq server is on the secondary server.
Note that the only machine that can both ping and ssh/scp/etc by hostname is nibbler, which also happens to be the only one of the three running RHEL5.3 instead of FC13. Other virtual and physical machines running on the 192.168.31.0 and 192.168.30.0 networks (all running RHEL5.3) work just like nibbler does. So the problem seems to only affect machines running FC13.
Final note: selinux is disabled, iptables is disabled, ip6tables is disabled.
Other than that, discovery is a brand-spanking-new install straight off of the FC13 DVD. atlantis has been around longer, but its just a file server so I haven't done anything too crazy to it.

I have set up an Ubuntu 10.10 server with SAMBA shares and Apache web server. Everything was working fine. Then there was a power failure and after I restarted the server the XP pc's can see the server using the hostname. They can only see it using the ip adress. I haven't change anything on server or client side. Just the restart of the server.

I've completed the installation of a CentOS server.Running the setup utility as root, ive set up a static IP and installed apache. Now this works ok. I can type in the servers IP address from my browser/putty/winSCP and access the server within the intranet. The problem is that i would also like to access the server using its hostname, e.g. http://centos or whatever Currently i cannot do it. I've searched the forums, edited the /etc/sysconfig/network and /etc/hosts to no avail no matter what i do i cannot access it. i've disabled some services so im not sure if this is the fault.

I have setup a web server, ftp, ssh with ubuntu server which is working with phpmyadmin and webmin installed with it as well. (I am considering upgrading to 10.04LTS when it comes out)
However I cant get to my website with the domain name that I am using from dyndns. From on my LAN I can get to my server but using it ip address (10.10.0.200) and it work fine with ssh and ftp as well. But when I try my public address or my name it does not work. I am using IE8 as I am using a windows machine. Out side the network the domain name wont work at all, but I tried my public address and everything worked perfectly.
I have recently installed ddclient to see if had made any difference but no luck. But I am keeping it there as it is working and updating my ip address.

How should I set up my webserver when using dyndns?My server lives behind a private router, and I opened a nonstandard port for it (xxx.dyndns.org:6789)I need to be able to access the webserver both from behind the router, and from outside. But espescially wordpress needs to have a defined specific site-url for each site, which I can not get working both inside and outside the router. Inside I now just just the local ip-number, which works ok. To access the server from outside, I have to redefine the site-url to "xxx.dyndns.org:6789", but then it is not accessible from behind the router.

I am using samba version 3 (probably), and the problem is that the linux based nas can only be accessed via its ip 192.168.x.x but not its hostname /server string appointed by the smb.conf file:
Code:

netbios name = NAS
server string = NAS

Server has been moved to a different locations and so the IP has been changed now the hostname is changed to something other that what it was before.
Could it be the rDNS that is causing this?
Note: this is not a DHCP connection.

wonder if anyone might have a clue with this. i installed filezilla because i wanted a nice ftp client, but when i tried connecting to the server with filezilla, i get this:
Quote:Connection attempt failed with "EAI_NONAME - Neither nodename nor servname provided, or not known".
yet when i googled that, i mostly found hints that said "your hostname's invalid" or "check the spelling of your hostname". well, those aren't it. i can login to this ftp server successfully through both firefox and by using a gigolo-gvfs-thunar combo.i even uploaded a file with the thunar route. and nslookup is able to see it. so what's with filezilla? by the way, this ftp account of mine is very old....i've had it for probably 10 years, and haven't logged in for 5. i'm surprised it still works.
also, why am i trying to work with filezilla when i have gigolo-gvfs-thunar? because thunar locks up and becomes completely unresponsive for a couple of minutes whenever i try to do any ftp'ing with it, even though it works. if i even so much as click on a file in my ftp directory, i have to wait two minutes before the window comes back and highlights the file i clicked.
UPDATE: just tried connecting via ftp in the command line, and no luck. so apparently it's not just filezilla. maybe i just can't ftp directly to that host anymore? but if so, then why are firefox and gigolo able to connect? networking is not one of my strong points, so this is confusing to me.
update again whaddya know, maybe i'm slowly starting to get some brains when it comes to networking. though i won't say i "figured it out"....but i did make it work. i just used the ip address nslookup reported and was able to ftp to it with both filezilla and the ftp command line. i forgot to mention that i'm behind a firewall (my router), and i guess the hostname is not in the router's DNS, if my tiny understanding of routers is correct. but connecting to the ip address directly is apparently not a problem.

I've only installed Ubuntu 10.04 Server yesterday, and it was the first time I had ever used it. As far and I can tell I have my Apache server up and running. When I go to localhost I get the 'It works!' page.
I tried checking my port in Windows, after I have Xampp loaded up, it says the port is working fine, and the site loads up properly, which leads me to believe the problem not in my router.
I've installed ddclient and put the proper information in as far as I can see but it still doesn't work. I've been testing my port here: [url]
And here is what I have in my ddclient.conf:

I'm trying to create a VPN-Tunnel so that I can access my home-LAN via internet. I've got a Draytek Vigor 2710n Router and a T-Online Internet connection.
For the reason, that my WAN IP changes about every 24h, I've registered at www.dyndns.org. When I've understood dyndns correctly, my router tells my ddns host, which WAN IP it has and my VPN clients requests this IP from the ddns host? What ever, I activated DynDns and created an account. Provider is dyndns.org, type is dynamic. Domain name is XXXX.dyndns.org. Username and password is set as given by www.dyndns.org. When connecting and checking the log, it seems to work as the result is:
"DDNS is updating
A= "username", H="address given by dyndns.org", U=1
Connecting to the DDNS server
Return Code= good (IP Adress)
Updated successfully."
Anyway, I'd like to start with PPTP, because it seems to be the easiest and most compatible solution (although not the savest).
I'll begin with my router's setup. I've activated PPTP VPN Service. Dial-In Authentication is PAP or CHAP. Dial-In Encryption is Optional-MPPE. Mutual Authentication is off. Next is the Dial-In Users setting. I've created an account. Timeout is 0. Dial-In Type is PPTP. Username and password is configured. That should be all concerning the router.
Now, I'm trying Ubuntu 10.10 to create the VPN tunnel. Gateway is XXXX.dyndns.org Username and password as setup in the router's menu. Authentication method is MSCHAP and MSCHAPv2. Use Point-to-Point encryptions is activated. Security is Default and Allow stateful encryptions is activated as well. Next 3 checkboxes are unchecked and Send PPP echo packets is activated.
Well, it doesn't work. I must admit, I'm a noob at VPN, but I really don't have a clue, what I'm doing wrong. Perhaps you can tell me?
PPTP VPN to my university via Ubuntu works.

I have recently developed the need for having a file server and am interested in setting up my desktop as a Samba File Server. The problem is that I need to be able to access it from outside networks (physically I'm about 10 miles away from my home network),o I need to also set up some sort of DynDNS service so that I can access the server from anywhere.With this, with setting up a DynDNS, setting up Samba, and setting up my machine to be secure enough for these types of actions. (I just want to make sure it is secure enough since it will need to be detectable from the internet.)

If you are running a home server/website, and want a domain name, currently you can use dyndns and others etc. to get a free one and use that so people can find you by name. So my question is, can it be done on your home server without having to use eg dyndns or others.

In Gnome Places->Connect To Server dialog, I am having problem using the Custom Location Service Type. I enter in the URI as
Code:
smb://username:password@ipaddress/share_name
I get an pop up error message that says:
Quote:
Cannot Connect To Server. You must enter a name for the server.
Which would be fine if there was actually a place for me to enter the name which there is not. What am I doing wrong. This is the first time I have tried using the Connect To Server dialog. Normally I just use a script I wrote to mount my share in a folder on my local drive as some programs cannot access the mounted network folder. In a browser all I have to do is:
Code:
smb://ipaddress/share_name
I tried using Windows Shares, but that did not work either. It does work if I click on network and access the share that way, but some programs like firefox and a few others that I want to save a file to my network drive do not show the network unless the share is mounted in a folder. So, I wrote a script:
Code:
#!/bin/sh
#mount ext storage drive
mount -t cifs //192.168.0.2/files -o username="username",password="password" /mnt/files
This works and I can use this, but it would be handy if I could just use the Connect To Server dialog.
