Topic: please help with native dyndns

[xavier]

native configuration dyndns server sme 7.5, the installation and configure but does not link, but you have not installed ddclient looking dyndns found some settings but leave this off and disabled, and configuration to enable and make it work properly. I hope your answer thanks

[cactus]

I would love to answer you, but I have trouble understanding what you want. Could you try and explain what your issue is again (being a bit more extensive).

It is unclear to me what your problem is, what you already did and what do you mean by:

looking dyndns found some settings but leave this off and disabled, and configuration to enable and make it work properly

It is difficult to understand you due to poor english grammar.
Please try to phrase the description of your problem more clearly.
Please answer the following questions as clearly as possible.

Is your server in server and gateway mode or server only mode ?
Do you use a modem/router in bridged mode or do you use a standalone router which provides all services to your LAN ?

What is your dyndns domain name ?
Did you add this domain name to your server in the "Configure this server" option ?

I read your comment as being you have NOT installed ddclient and not configured it, correct ?

I think you are asking how to configure the built in dyndns client to update your dyndns account, is that correct ?

Please advise us step by step what settings you have made to your server
ie what is the main domain name
how did you configure the server please, in the "Configure this server" admin panel ?

[xavier]

sorry for the grammar I'm not very good in English and used a translator

Is your server in server and gateway mode or server only mode ?
server and gateway

Do you use a modem/router in bridged mode or do you use a standalone router which provides all services to your LAN ?
router in bridged mode

What is your dyndns domain name ?
programasremotos.dyndns.org

Did you add this domain name to your server in the "Configure this server" option ?
yes
name = programasremotos
domain = dyndns.org

I read your comment as being you have NOT installed ddclient and not configured it, correct ?
yes

I think you are asking how to configure the built in dyndns client to update your dyndns account, is that correct ?
yes yes yes

Please advise us step by step what settings you have made to your server
ie what is the main domain name
how did you configure the server please, in the "Configure this server" admin panel ?

1 domain = programasremotos
2 = dyndns.org hostname
3 local ip = 192.168.1.10
4 macara = 255.255.255.0
5 function = server and gateway
6 external access mode = server and gateway "dedicated"
7 targeta network configuration = "eth1 local" and "external eth0"
8 = external interface configuration "using dhcp" "send ethernet address as client identifier"
9 dynamic dns service = ww.dyndns.org - Free Service
10 name
11 password
Dhcp server configuration 12 = "off" does not provide service to the local network dhcp
13 dns server address corporate = "" empty

I await your response.....

[johnp]

What is the ip adress of your external nic?(should be viewable from server-manager configuration, review configuration) Are you using dsl for your connection? From what I see, dyndns has a private address.

[janet]

xavier

Did you add this domain name to your server in the "Configure this server" option ?
yes
name = programasremotos
domain = dyndns.org

name = would typically be a servername which is identifiable on the local network (LAN) via samba filesharing eg server1 or server2 or a location specific name eg office1 or office2 etc

domain = would typically be the full domain name eg in your case programasremotos.dyndns.org
 

how did you configure the server please, in the "Configure this server" admin panel ?
1 domain = programasremotos
2 = dyndns.org hostname

Step 1. Please enter the primary domain name for your server. This will be the default domain for your e-mail and web server.
In your case this should be = programasremotos.dyndns.org

Step 2. Please enter the system name for your server. You should select a unique system name for each server
In your case this should be = server1 or server2 or office1 or office2 etc

3 local ip = 192.168.1.10
4 macara (subnet mask) = 255.255.255.0
5 function = server and gateway
6 external access mode = server and gateway "dedicated"

all appear OK

7 targeta network configuration = "eth1 local" and "external eth0"

OK, but usually select normal eth0 is local, eth1 is external
This choice depends on position of cables connected to NICs, swap the cables if necessary

8 = external interface configuration "using dhcp" "send ethernet address as client identifier"

OK, this will depend on your Internet conection and should be as advised by your ISP, which in your case appears to be Cable

9 dynamic dns service = ww.dyndns.org - Free Service
10 name

This should be your dyndns account login name eg mydyndnsaccountname

11 password

This should be your dyndns account login password eg mydyndnspassword

Dhcp server configuration 12 = "off" does not provide service to the local network dhcp

OK if this suits your network. Typically if your SME server is your only server on the network, then you would select = On Provide DHCP service to local network

Do you have another DHCP server on your network ? If not, you should select = On

13 dns server address corporate = "" empty[/b]

OK and usually best left empty in most situations


From the above your error seems to be that you have entered your server name and main domain name incorrectly. Perhaps also your DHCP server setting is wrong.

Run the "Configure this server" option again when logged in as admin, and correct the errors.

[xavier]

Corrections "dns not working"

Note: eth1 and eth0 local external "test runs of the internet" "work test network" with local eth0 and eth1 external "Internet test does not work" "work test network"

Does your ISP service provide a static IP or a dynamic IP ?

Go to http://www.showmyip.com/
and determine what your current external IP is.
Then go to the dyndns.com site and login to your dyndns account.
Change the IP for your domain to be the currently shown external IP at http://www.showmyip.com/

See if your web server is then accessible from the web.

External IP address / subnet mask   192.168.1.111

As johnp points out, this appears to be a local IP ???
I'm not sure what this should be for a Cable connection, but I imagine there should be a IP displayed which is in the valid public IP range.

Web server   www.programasremotos.dyndns.org

For this type of www URL to work you will need the * wildcard enabled at the dyndns site, which I believe is no longer available on free dyndns accounts. You have to pay now to get the wildcard functionality.
Otherwise just access your server using http://programasremotos.dyndns.org

Try this also. From a workstation on your LAN (behind your sme server gateway), do a port scan check at www.grc.com to see what ports are open.
Edit: Maybe your ISP is blocking ports for web & mail servers (ports 80 & 25).

[johnp]

xavier,

We really need to know what kind if internet access you currently have. Make and model of your gateway would help.

As now it appears to be doing nat to your external nic. Depending on your equipment you may have to do the dyndns updates on it and open all ports to your sme. Although is is also possible with configuration changes, it could assign the true internet ip address to your external card.

This topic should likely be moved, since it doesn't appear to be a sme issue.

[CharlieBrady]

Local IP address / subnet mask   192.168.1.10/255.255.255.0
External IP address / subnet mask   192.168.1.111

This is not a valid configuration.

Your configuration has me confused. The way I see it is:

Internet--[Cable/DSL]UKNOWN[eth]--[WAN]WRT150N[LAN]--[eth0]SME[eth1]

The WAN on the WRT150N has 186.69.249.28 as it's current ip address the LAN value address is unknown
The WRT150N through DHCP is assigning 192.168.1.111/unknown mask to [eth0], and [eth1] has a static value of 192.168.1.10/24.

There are several things that need to be fixed and the way to best accomplish this depends on your goal.

What is the WRT150N really used for? If just wireless access, it could be converted to an access point connected to [eth1]

My preferred setup would be:

Internet--[Cable/DSL]UKNOWN[eth]--[eth0]SME[eth1]--[LAN]WRT150N

This would require turning DCHP on for the sme and off for the WRT150N, I would also make sure that the address for both resi9de on the same subnet and do not conflict with eath other or the created range

Do you use a modem/router in bridged mode or do you use a standalone router which provides all services to your LAN ?
router in bridged mode

Is your router really in bridged mode (ie pass through all data), and have you also disabled the firewall, the DHCP server, the login client and all other functions/services in the router ?

[xavier]

la conexion funciona via ssh con ip y dns muchas gracias, I have another ploblema in port forwarding
problem in the configuration firewall and gateway

in server-manager
----------------port forwarding
----rule     
protocol  TCP
source port 3389
target host ip 192.168.1.100
destination port 3389

port is not open and is not a gateway for connection

where reviewing firewall rules, and open or closed ports
in /sbin/iptables  =  data unreadable
in /etc/rc.d/init.d/masq   = rule port forwarding not visible

in tutorial
eg to leave open some ports ie 222 & 2000-2010, block in ranges
config setprop masq TCPBlocks 0.0.0.0/0:1-221,0.0.0.0/0:223-1999,0.0.0.0/0:2011-65535

Update the config changes and restart masq
signal-event remoteaccess-update
/etc/init.d/masq restart

this rule's okay port 22 and 3389 or wrong
config setprop masq TCPBlocks 0.0.0.0/0:1-21,0.0.0.0/0:23-3388,0.0.0.0/0:3390-65535

otherwise but already exist template default or system
Create a custom template and list the IP's
mkdir -p /etc/e-smith/templates-custom/etc/rc.d/init.d/masq/
pico -w /etc/e-smith/templates-custom/etc/rc.d/init.d/masq/40DenyRiffRaff
/sbin/iptables -A INPUT -s 69.212.12.76/32 -j DROP
/sbin/iptables -A INPUT -s 88.28.215.11/32 -j DROP

expand and restart
/sbin/e-smith/expand-template /etc/rc.d/init.d/masq
/etc/init.d/masq restart

which would be a correct rule for ports 22 and 3389
help where you can review and configure firewall rules, thanks.......
