Ubuntu Networking :: VPN With Authentication To External Radius Server?
Jun 25, 2010
this is all I need simple VPN with authentication to external Radius server. Here is what I have done to try and get this goal accomplished. 1st try using PPTPD and Radius plugin No matter what I have tried (long explanation here [URL].. I can't get PPTPD to talk to my Radius server, even though I can authenticate using the same server and radius server using pam radius. PPTPD just won't, and so far the POTOP mail list has been quiet since my post to them and no replies/ideas in my other post, see forum link above.
2nd try using OpenVPN and their pam auth plugin. I give up on this one! I have the server working great BUT! As soon as I enable the plugin /usr/lib/openvpn/openvpn-auth-pam.so in the config I get this when trying to start the VPN server. kernel: [3725586.167177] openvpn[28364]: segfault at 0 ip 00007fd6e5e38fb4 sp 00007fff434f18f0 error 4 in openvpn-auth-pam.so[7fd6e5e38000+3000] Google turns up nothing on Segfaults on the openvpn-auth-pam.so Ug at my wits end, anybody have any other suggestions? I'm at a total loss ATM.

How to configure Web authentication against RADIUS server on Debian Jessie, because the package libapache2-mod-auth-radius is not available on debian mirrors.
I would like to know what happened to this package and what is the newest way to configure radius auth. Some people have told me to compile this package, but is there not an easier way to do that?

I was asked to setup 802.1x Port Based Authentication for users connecting to a Managed Cisco Switch. From what I was told, it should work like this:
- User plugs workstation into switch.
- Workstation asks user for radius credentials.
- Workstation is then able to authenticate to the Radius server.
- After workstation is authenticated, the switchport then becomes unrestricted and allows the workstation to communicate on the network.

I have one Centos Server and I want to forward root mail to 1 external account: [URL] I installed sendmail and created /root/.forward with this content: [URL] and I sent a test mail with this command: /usr/sbin/sendmail root <prueba.txt But nothing was forwarded.
After that I ran the same command with the verbose option:
/usr/sbin/sendmail -v root <prueba.txt
And this is the output:
root... Connecting to [127.0.0.1] via relay...
220 localhost.localdomain ESMTP Sendmail 8.13.8/8.13.8; Wed, 3 Nov 2010 21:09:39 -0600
>>> EHLO localhost.localdomain
250-localhost.localdomain Hello myfriend [127.0.0.1], pleased to meet you
250-ENHANCEDSTATUSCODES
[code]....
For some reason sendmail tried to connect to example.com smtp server and couldn't reach it. I am sure this is because the smtp server for example.com domain is not example.com is mail.example.com. Besides mail.example.com requires authentication, username , password and the smtp port is not the default 25 is 9999. configure sendmail to forward root mail to a smtp server that requires authentication, username, password with a not the default 25 port?

I need to set up a Radius server for use in an ISP which will be wireless internet only.
I had thought to use Centos maybe and install and somehow configure Freeradius.
I have little experience with Linux, but am a Windows Admin, and use Linux a little.
My questions would be: Is there a best distro that i should use?? I have used Ubuntu the most, but not sure if it is best to use for this project.
Freeradius website has documentation but it doesnt tell me much about how to get it all up and running, What we want is Authentication and Accounting and from what i can see Freeradius is a good option? Is there anything better that i can use? We will be eventually having approximately 5000 clients.

I have installed FreeRadius to a Debian Linux server.I have configured an account called Support to run the Radius as I didn't want Root to be the user to run this.I want Radius to start up automatically after the system is rebooted but I don't know how to do this. I am new to Linux so please bare with me. If the system is rebooted, is it possible for the Support account to be logged in automatically? Is there a script I can create to automatically login the Support account? This may not be secure but it has been requested. Also the main question is after a reboot can the Radius be configured to automatically start without the need for someone to login? So if the system is rebooted and then goes back to login prompt, can the Radius then be running?
I have had a good search about scripts but with my limited knowledge it isn't too easy.
After reading it also said something about using rc.radiusd which will automatically start Radius after a reboot, but again I cannot understand exactly what I need to do.Please can someone help out with this and let me know if I am on the right track? Will the start-my-radius.sh script work after the system is rebooted without someone actually login and how do I get it to work?Please explain clearly as this is all a bit technical for my liking and not understanding it well!

Am using Fedora 15, in which i was able to configure the proxy server and authentication. i confirmed this by configuring web broswer and it works. Now the problem is that i want to deploy it out to other computer system(client) i dont want to use the transparent proxy because the Proxy Authentication will not work.
I even tried to configure a DHCP server if it will work but i cant still configure for other computer system to work.

I'm rather (VERY) inexperienced when it comes to Linux, but Fedora 14 is the environment I have to use on my laptop at work, so please forgive any dumb that comes out of me.
How do I tell php to send an email with mail() using an external mail server?
The situation: I've got apache/php running a webserver on my local machine. It's for dev purposes only, and the website files I'm using are checked out from our SVN. This lets me make changes to our website while not actually changing our website.
I've come across an issue I'm fixing where I need to verify that an email is successfully getting sent out, and unfortunately, this email is sent out using php's mail(), and not our website's usual $mail object. Unfortunately, I don't have the authority to change how this sends out right now, just when it sends out.
I've been running everything fine on my machine for a month now, and haven't needed the mail stuff until now. How do I tell php to send an email using an external server?

I am running Jaunty 9.0.4. I have go through a proxy to get out to the net. It was working. Sometime yesterday it was unable to resolve the proxy server. Can't even ping it. Other computers can. I even switch cables to no avail. What could block the proxy server? I can't even ping google.com Was it something I installed through add/remove software? Has anyone seen something like this before and even better has a solution or can offer a way to troubleshoot this? I can ping myself and the default gateway server.

I have an apache server running on my ubuntu machine. I can view them using my local ip (192.168.1.6):80/. And my friends can view the things hosted on my server using my external ip (example http://123.123.123.123:80) but when a friend links back to me to show me what they are looking at and share the moment, I can't view the link, it simply redirects to my router login page.
I had an older linksys router and this could work fine. I could click on the links with my external IP and it routes back to my server for viewing.
Remember to note that I am on the machine that has the server, and I'd like to be redirected out and back to it so we can share pictures back and fourth without me having to replace the external IP address with my local one just to view that link in the browser.

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.

I've been running a Samba server under RedHat 8 for five years without a hiccup. I want to cut over to a F10 box but cannot get shares accessible. smbclient attempts fail over NT password error. SELinux is disabled. Server is visible on the network. Users require no password access to shared data.
smb.conf follows:

I am setting up a CentOS box as a NAT firewall that needs to also send mail. It needs to send this mail using an outside provider's SMTP. The provider requires SMTP over SSL. None of the machines inside the NAT will ever send mail except via the provider's SMTP nor will they ever receive mail except to local clients via the provider's IMAP servers.
So for the example the machine is TESTMACHINE. There is one internet facing ethernet port connected to a DSL modem via pppoe.
The SMTP it needs to send mail via is mail.host.net which requires SMTP over SSL (port 465) and username/password authentication.
The sendmail documentation is quite confusing on how to get this simple setup operating, so an example showing the appropriate changes to sendmail.mc and other require config files.
