Hi, I have a few remote user who use a PPTP based VPN. The server is running PoPToP (http://www.poptop.org/), and a pppd patched to support MPPE/MPPC for (some) added security. Currently, users authentication information is stored in plaintext in /etc/ppp/chap-secrets. I'd like to be able to put users into LDAP, and have ppp authenticate either directly against LDAP, or against Samba (with an

Hi. I'm trying to add a client running Windows XP Professional SP2 to a PDC server running Samba 3.0.13 over a VPN tunnel made with PPTP. The VPN tunnel works without problem, and I can see the shared resources on the PDC from the client searching the server with its hostname (I can access to \\server). When I try to add the client to the PDC, Windows XP ask me for the root user, but after

Hi all, I have a client that has 4 subnets within his building, internet, office, business center and wireless. My plan is to use Shorewall but I have never tested it with more than 2 interfaces. Is this possible? Would there be any issues that might arise. Each subnet would have access to the internet but there will be no communications allowed between the others. Thanks in advance....

I am trying to get Samba to authenticate to a Win2k DC. The error I consistently get is "Failed to verify incoming ticket" Using wbinfo I can pull the user and groups from the DC. Using krb5 I can get a good ticket from the DC. I have the winbind options in my smb.conf exactly as listed in the docs. The Linux box did a "net join ads" no sweat. After sitting a while, I no longer

Good Morning Everyone, I have a server that runs Shorewall/Samba/PPTP (Poptop). When we try to connect to the PPTP server from outside of the company, the Windows XP pro client can establish the connection. We can then ping the server and the clients behind the server without any problem, but the issue becomes that we cannot map to any of the shares on the samba server or to any client for that

How to setup a vpn server on centos? I can't find the pptpd in any repo

I''ve got what I think is a fairly simple home network configuration with one Linux box functioning as the firewall, VPN server, DHCP server and file/print server. I am having trouble configuring both a VPN server (PopTop) and the firewall rules for a W2K PPTP VPN client. The VPN server runs on the firewall machine and the VPN client runs on a W2K machine behind the firewall. The VPN

I am running shorewall 1.4.8-1 on my firewall. I am also running poptop on this firewall for remote VPN clients to connect to our local network. I would like to set some options in pppd, so that after 2 failed user/pass attempts are tried, the IP address is blacklisted, and an email is sent to the admin of this IP address that has been blacklisted. I know this may be more of a ppp question than

Hi all I have succesfully set up PPTP VPN access to my company using PoPToP/pppd (thank you Tom for excellent documentation), everything works fine so far. Problem is security. As I understand it, since PPTP ports trough tunnel are opened to whole Internet (have to be), access verification is now based only on username/password combination. Can level of security be raised with MAC verification?
