Networking :: Bind External IP Address To Internal IP Address?

Jun 7, 2009

I have a few external IP's assigned to me by my ISP. I have IPcop as my router/firewall. I am wondering how to bind 1 of my external ip's to my internal ip address. So I do not have to port forward, etc. For Example, 77.77.77.77 to 192.168.1.123 and on the server it see's the external IP address.

Server :: 98 - Address Already In Use - Make_sock - Could Not Bind To Address - 443

Oct 26, 2010

I dont know for what reason, I started having this message whenever I try to start httpd.
I commented "Listen 443", restarted httpd started correctly.

I issued "lsof -iTCP:443", I get

Quote:

I can not understand where this come from and why. It seems that it is IPV6 protocol which is in fact not enabled on the network card.

Also, I can not find or dont know where 443 is configured apart from ssl.conf or httpd.conf

Today, I have added xrdp applications in order to be able to connect using RDP.

Networking :: Can't Bind Send Socket: Address Already In Use

Feb 23, 2009

I am currently trying to get a B.A.T.M.A.N mesh network up and running. the thing uses UDP port 4305 for broadcasting to nearby nodes and it seems this port is closed or used by something else.

now i have tried to open this port with commands like

Code:

iptables -A INPUT -p udp --dport 4305 -j ACCEPT
iptables -A OUTPUT -p udp --dport 4305 -j ACCEPT

it still gives me the same error saying the socket cannot connect.any way for me to scan that udp port, see what is blocking it and open the thing up ?

Ubuntu Networking :: Internal IP Address Change?

Apr 16, 2010

Now I'm not too clued up about networking and IP addresses. However, I know that I have an IP address for my router (which is dynamic) and then all of my machines have internal address e.g.

192.168.0.2
192.168.0.3
etc...

My server, had the internal address of 192.168.0.4 but now has changed to 192.168.0.7 what causes this to happen? I have to change my port forwarding on my router to allow access to my server from outside my network.

Fedora Networking :: Establishing A Vpn Connection Using Vpnc / Error Failed To Bind To 0.0.0.0:500: Address Already In Use?

Nov 24, 2010

I am having difficulties in establishing a vpn connection using vpnc (or NetworkManaager-vpnc).

As long as the openswan IPsec daemon is running, vpnc-helper quits with the error message

Quote:

Failed to bind to 0.0.0.0:500: Address already in use
[user@computer ...]# vpnc-helper --local--port 0

If I use NetworkManager-vpnc, then establishing the connection simply fails.
Using the --local-port 0 option does not change anything.

If I stop the ipsec service (service ipsec stop) then establishing the connectiong works, both with NetworkManager-vpnc and the console tool, but apparently the network traffic is not routed via the VPN - in my case this means that I cannot access hosts within the vpn and stuff.

Funny thing is - on my notebook from where I connect via WLAN, everything works fine. With Fedora 13 everything works fine, too.

Does anybody have an idea how to enforce that the vpn connection is actually used?

Ubuntu Networking :: Static IP Address And The Install Configures For A DHCP Configured Address - Network Not Starting

Dec 16, 2010

Version 10.04 LTS. Installed desktop version and network worked but I needed a static IP address and the install configures for a DHCP configured address. I tried changing to static address using the System->Preferences->Network Connections application but was unable to get the system to come up with the network up.

So I manually modified the /etc/network/interfaces and the /etc/resolv.conf files. I restart the system but when I do an ifconfig, I don't see a configured IP address on eth0 (only the loopback address). If I run /sbin/ifup eth0 everything then works fine and ifconfig shows the correct address bound to eth0.

My files are as follows:

Networking :: Dynamic IP Address With PTR Record Versus Fixed IP Address Without?

May 7, 2010

I am running my own Postfix mail server. Some time ago I noticed that most email was rejected because of the server's dynamic IP address. So I got a fixed IP address. However then I noticed that some mails got rejected due to failing the reverse DNS check. So my ISP told me to get a range of IP addresses and they could then create a PTR record for one of those addresses. That is now running but it turns out that the IP address used for the PTR record is a ... dynamic IP address. So Spamhaus PBL rejects my emails again.

Networking :: Connect To External Computer Using Local Address?

Apr 9, 2011

I couldn't find an answer to this question (not including vpn) on different threads so decided to eventually post it, though it's probably easy one. I would like to connect to some application on known IP and port in the internet from my LAN computer. However to do so (I have some application, not any administrative constraints or not being allowed to) I would like to use local addresses. So, let's say - I want to connect to the external host VV.XX.YY.ZZ, port AA using 192.168.EE.FF port BB. Baically so far I have limitation in my application (too many places for possible error, to correct it right now - will change it in future). Is it possible that after my application sends request to 192.168.1.EE port BB, my Linux transparently translates it to VV.XX.YY.ZZ:AA? I tried iptables tutorials and some forums, but nothing seems to be addressing this issue. I don't know if it's event possible with iptables but am pretty sure this should be possible.

Networking :: Error: "bind: Cannot Assign Requested Address"

Jun 18, 2010

I have a small cluster (OSCAR, Fedora 8) and I was able to run some application software on it. Then lightning struck very close to the building. Fortunately I had unplugged all the power cables (because the cluster has not yet been moved to where the power lines are protected), but it seems that the institution didn't have any protection on their LAN cables, and so the whole building's public network cards are damaged. A costly lesson.

Anyway, when I tried to run the application software in parallel across the cluster (using the private network which is unscathed) I get the error message given in the subject line. I contacted the application software's help department as I thought I had perhaps forgotten to set something, but according to them it is a normal network problem.

Quote:

Check the /etc/hosts file and make sure that the nodes all have a single definition and you don't have lines like

127.0.0.1 localhost normnode3

and that normnode3 has the same address both on the master and on the node. try ping normnode3 from the master and see what address comes back 64 bytes from 164.190.57.105: icmp_seq=1 ttl=64 time=0.306 ms or is it 127.0.0.1. Then do the reverse. Also double check that you can ssh between nodes without password but I would expect a different error then. The command "hostname" returns gnlserv01, which is the public NIC.

After the lightning I had trouble getting the nodes to communicate "automatically" with each other, but it can be cured by starting the xinetd service and disabling the firewall on the master node (it's not too dangerous since I don't have a public interface at present and since I'm sitting behind the institution's firewall as well.) Just by the way, I would think that ther should be a file somewhere in which I could specify those two commands to take place when the master node is switched on. Could you perhaps enlighten me as to where and how I could specify it?

I was wondering whether I would need to explicitly start a bind-type service or something like that? (Since I had to explicitly start xinetd) I'm rather clueless really. I googled around and found that there is a named service, so I tried to start it, but I don't think it's installed on the computer. Therefore, since I have managed to run the application software in parallel previously, the named service is probably not the problem. Here is a copy of how my /etc/hosts file looks like:

Code:

# Do not remove the following line, or various programs
# that require network functionality will fail.
# These entries are managed by SIS, please don't modify them.
127.0.0.1 localhost.localdomain localhost

Ubuntu :: MySQL Not Starting When Bind-address Set To LAN?

Jun 17, 2010

I have MySQL installed on my Kubuntu 10.04 desktop machine which I use for developing web applications.First, all worked fine. But then I wanted to synchronize the database with the MySQL database on my laptop, so I had to allow connections from the LAN interface. So I addedCode:bind-address =192.168.0.100to /etc/mysql/my.cnf. This worked and the synchronization was performed. I want to do this on a regular basis so I would like to keep that line in there.The problem now is that MySQL does not start on system boot. When I start up, mysql simply is not started. There are no errors in /var/log/mysql/mysql.err or /var/log/mysql.err; these files remain empty.When I try to start it using 'sudo start mysql' I get the same result. The 'start mysql' shows up in 'ps aux', but the mysql process itself does not.Now, I found out that when I run

Code:
sudo -u mysql mysqld
The mysqld daemon does start, and the server works fine. To make matters even more strange, if I kill this
