Just installed webmin, can't access off localhost

jon_k · 05-03-2004, 10:49 PM

Hello, I've just installed webmin 1.140

I can access it by lynx localhost from SSH

but I cannot access it over the LAN by http://192.168.0.4 from my windows box.

This is strange because I can access apache this way.

I have the IP Access Control [thats a feature within webmin config] set to not limit any IP addresses, yet I still have this problem.

Running Redhat Fedora 1

What should I do? Thanks!

What port are you using for the Webmin server? If it is other than port 80, are you running iptables? If so, then make sure that you have a rule to allow that port. I think the default port for Webmin is 10000.

Yes, default port for webmin is 10000

I am not running IPTables, nor do I have "fedoras" firewall enable neither.

Well, I'm not sure about IPTables completley, wheres the iptables file located?

/etc/sysconfig/iptables -- right? heres the code for that file

Code:

# Firewall configuration written by redhat-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
:RH-Firewall-1-INPUT - [0:0]
-A INPUT -j RH-Firewall-1-INPUT
-A FORWARD -j RH-Firewall-1-INPUT
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
-A RH-Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT
-A RH-Firewall-1-INPUT -p 50 -j ACCEPT
-A RH-Firewall-1-INPUT -p 51 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 25 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 21 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
COMMIT

There appears to no mention of port 10000 (webmin default port)

I've also set webmins port to port 81, still no beans, still only localhost seems to be able to connect to webmin, whereas other systems on the LAN cannot.

Really appriciate anyones responce. Thanks

try add this line to the iptables file:

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10000 -j ACCEPT

this will accept new incoming connections on port 10000.
acces webmin with:

http://192.168.0.4:10000

you need to include the port and the http:// part!

greetz,

edit:
just for info, it works from localhost because this line in the iptables file:
-A RH-Firewall-1-INPUT -i lo -j ACCEPT
this means to accept ALL incoming connections from localhost

Thank you very much iluvatar!

It worked, I added that line manually and then restarted the system (changes didn't take effect until I restarted, and I don't know how to restart the iptables deamon.

If someone will mention how to restart iptables deamon so the changes take effect, I'd appriciate it! Thanks!

The command "/etc/rc.d/init.d/iptables restart" will flush the iptables config, and read the config file again.

DavidPhillips · 05-05-2004, 09:29 AM

Here's some commands for redhat / fedora

the firewall...
service iptables stop
service iptables start
service iptables restart

starting at boot...

chkconfig itables off
chkconfig iptables on

to save changes (if you entered iptables commands to setup some rules manually)...

service iptables save

I can't log into webmin remotely and as I read the following, I found out that I do not have the iptables file.
Any body knows how I can create or fix my problem that?

In another chat room I read that rempte log in is not on. Could that be the problem?

jlbrt · 12-29-2004, 07:37 AM

Try installing webmin-firewall, and configuring it.

Redleg · 05-27-2005, 12:27 PM

Found this subject helpfull regarding access to Webmin from a machine that is not localhost, but in my case I had to modify the line:

iptables -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10000 -j ACCEPT

to:

iptables -I RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 10000 -j ACCEPT

the first line places the accept rule at the end of the chian, after the reject rule. The port 10000 connection is rejected before it gets to the accept rule. The -I causes the rule to be inserted at the beginning of the chain. This may be unique to what I am using, Fedora 3, as it worked for the OP.

Posting this in case someone has the same problem as I did.

Thanks iluvatar for getting me pointed in the right direction.

I,m running Squid Proxy on my Suse Linux box, and I down loaded Webmin so i could more easley configure the proxy. When i first installed it i could login with no problem. I turned the machine off to move it in my lab to a new location, started the machine up and tried again to access the local proxy and got this error

Firefox can't establish a connection to the server at linux-ym0b:10000.

Can anyone help me with this?

You'll probably need to start Webmin again. Look in the /etc/rc.d/init.d directory (I think that's what it is on Suse) and look for a script for webmin. Use that to start Webmin again.

If that works, then add that command into the rc.local file to make Webmin start automatically.

ttkkdog · 01-10-2008, 04:20 PM

I went to directory /etc/rc.d but there was know init.d. Is there a command to restart the service? You will have to excuse me I'm new to the Linux world.

shubb · 01-10-2008, 04:31 PM

There is a command to restart, but there has to be an init script first. Try the command "service webmin start".
If the installer created the init script, then that should work.
