linux vpn logging openvpn pptp
I currently have a default setup of OpenVPN and PPTP. I was wondering how I can enable the most verbose logging of the services so in case of abuse we can track down who’s IP did what?

I’m trying to install a VPN on one of our servers for use within my campus so that we can play some games, but I appear to be getting errors when I try to connect, as shown below. Not quite sure about all this and what’s going wrong, I followed this guide: http://www.photonvps.com/billing/knowledgebase.php?action=displayarticle&id=58We are trying to use the VPN with our macs, but they seem to be encountering some authentication errors from what I have gathered.

Have a Macintosh (10.8.2) that connects just fine to a CentOS 6.0 virtual private server (OpenVZ, with PPP added by the host) via PPTP.A Windows 7 Home Premium client (virtualized in Sun’s Virtual Box), on the same computer, using the same Ethernet connection, cannot connect to the Linux VPN server.I have iptables disabled (for testing) on the Linux box. I have the Windows firewall turned off. /var/log/messages looks like this, for a Windows connection:Oct 12 18:44:30 production pptpd[1880]: CTR

I’m trying to connect to a PPTP server which is sat behind a Cisco 881 NAT router. The server is running Ubuntu Server 12.04 and is running Poptop pptpd as the PPTP daemon listening for connections.As discussed in my other question, I’m trying to setup a Cisco 881 router to replace my old Linksys WAG320N. This same server and WAN connection worked fine with the WAG320N with no special configuration, other than allowing 1723 in through the firewall.On the Cisco 881, I’m using the newer ip nat ena

I set up a Seagate DockStar with Debian Squeeze as a litte server in my home network. I’d like to access it from outside my own network now, so I need a VPN connection. BTW, I don’t have a router with an integrated VPN server. I already have a “big” Windows XP server running which I can access via a PPTP VPN tunnel. That was pretty easy, but now with Debian, I have some problems setting up the VPN connection.I installed pptpd via apt-get install pptpd already. This is my pptpd.conf:# TAG: ppp #

Brand-new install of CentOS 6.3. Followed this guide: http://www.members.optushome.com.au/~wskwok/poptop_ads_howto_1.htm And I got PPTPd running [v1.3.4]. I got the VPN to authenticate users against our Active Directory using winbind, smb, etc. All my tests to see if I’m still authenticated to the AD server pass [“kinit -V [email protected]”, “smbclient”, “wbinfo -t”].VPN users were able to connect for like . . . an hour.

I am a network engineer having quite limited experience with Ubuntu. I have been following up these online instructions to set up a pptp server but without much luck to get it to work. My server is a vm running an Apple Xserve behind a Cisco firewall. I made sure tcp 1723 and GRE are opened for the box. Below is the syslog output, looks like I always got stuck at GRE: Bad checksum from pppd. I’m running Ubuntu 10.04.Sep 24 13:21:53 ubuntu pptpd[1231]: CTRL: PTY read or GRE write failed (pty,gre)

I recently upgrade my 12.04 desktop installation to 12.10 and then to 13.04 hoping that my problems with VPN would disappear. I can’t put my finger on when, but in 12.04, I just started noticing that the PPTP service was crashing every 2-5 minutes, making VPN essentially unusable. Finding nothing satisfying in the forums, I decided to be a little more bold and upgrade – both to check out the new version and hopefully have VPN automatically be repaired. By the way, it’s been working great unti

I’m trying to connect to my corporate VPN using a laptop running Ubuntu 10.04. It’s a company laptop but as I have chosen to run Linux rather than “a proper” OS, I’m mostly on-my-own as far as getting these things working. Normally that’s OK because I am almost always successful – except this problem has had me stumped for several weeks now.The problem is that I am unable to access the VPN from my home network. I am using the Gnome Network Manager interface to configure the PPTP connection but n
