Title: no ftp from outside
Post by: thierry on January 24, 2003, 12:34:44 PM: Hi,

I'm unable to connect to my e-smith server by ftp from outside.

Here is my configuration :

Server Mode   servergateway
Local IP address / subnet mask   192.168.1.254/255.255.255.0
External IP address / subnet mask   192.168.65.17/255.255.255.0
Gateway
Additional local networks   No additional networks defined
DHCP server   enabled
Beginning of DHCP address range   192.168.1.100
End of DHCP address range   192.168.1.250

I can ping it from outside, but not accessing it using ssh or ftp.

All ports are open :

Starting nmap V. 3.00 ( www.insecure.org/nmap/ )
Interesting ports on localhost (127.0.0.1):
(The 1590 ports scanned but not shown below are in state: closed)
Port State Service
21/tcp open ftp
22/tcp open ssh
25/tcp open smtp
53/tcp open domain
80/tcp open http
113/tcp open auth
139/tcp open netbios-ssn
443/tcp open https
980/tcp open unknown
981/tcp open unknown
3128/tcp open squid-http

I'am registerded with dyndns.org to have a dynamic dns.

What must i do ?

Thanks a lot for your help.

Thierry

Post by: thierry on January 24, 2003, 01:44:34 PM: Yes.

In remote access I have :

FTP access limits : Normal usage

Post by: Bill Talcott on January 24, 2003, 05:52:21 PM: But what do you have for "FTP user account access", which determines if external FTP connections are allowed?

FTP user account access : public

Post by: Robert on January 25, 2003, 06:03:06 PM: It looks like your External IP and Gateway are not set correctly. How is your server connected to the internet? Can you successfully run the internet access test in the admin console? How did you run the ping test? Are you sure you didn't just ping an IP that you had before, but is now assigned to someone else? What does "/sbin/ifconfig" say?

Post by: thierry on January 27, 2003, 05:16:59 PM: My server is connected using a DSL line (speedtouch USB modem).

ifconfig says :

Internet access test on using server-admin is OK.

It seems you are right, when I try to ping sockho.dyndns.org, it doesn't works.
But when I try ping 80.14.183.72, ping works.

It might be a dyndns problem, but ftp still not works.

I run the ping test from our server (www.sockho.com).

Thanks for your help.

Post by: Robert on January 27, 2003, 07:35:35 PM: Try /sbin/e-smith/signal-event ip-change 80.14.183.72 (or whatever ip ifconfig currently reports)
That should correctly set your external ip and update your firewall rules accordingly.
Title: Re: no ftp from outside
Post by: thierry on January 28, 2003, 12:24:16 PM: it works !

You are right.

Thanks to terry, bill and robert for your help.

In fact the problem was my modem is deconnected every few hours, but I don't know why (I use a usb dls modem - alcatel speedtouch), so I made a little script launched every 5 minutes by cron, in order to reconnect it. So I need to add signal-event in this script.

please 2 questions more :

- How can I get my ip address from a script ?
- What can be the reason of my modem is disconnected every few hours ?

I installed the newest driver from alcatel, but no change...

Thanks a lot to all.

Post by: Robert on January 28, 2003, 02:05:59 PM: You shouldn't have to make your own script to signal ip-change. There already is a script to do this that should run automatically whenever your computer reconnects to the internet. You need to figure out why this script is not run automatically on your server. Have a look in the messages log for useful info around the time that your modem makes a connection.
Maybe your ISP is kicking you off the net every few hours. My ISP kicks me off about once a day. I have a regular PPP connection to my ISP that is set to "continuous connection" in the admin console. Whenever my ISP terminates the PPP connection, the server automatically reconnects and runs ip-change.
Maybe you can start a new thread to ask if anyone knows of any peculiarities with your modem or ISP.
