Mac OS X 10.7 VPN PPTP 'Disconnecting' pppd process hang
The PPTP client on Mac OS Lion will not discconect from a Win 2003 PPTP Server.
I experience a forever 'Disconnecting' in the status bar.
Running a process list i.e
# ps -eaf | grep pppd
I can see pppd is still running, despite the disconnection request.
I also have a Fortinet SSL VPN client which once disconnected - I can't re-establish a connection, again due to pppd hanging.
sudo kill -9 <pppd proc id> won't work. The only way to re-connect is to reboot the laptop.
This takes forever as I assume the O/S is trying to kill all processes and pppd won't close!
I found the culprit to be a kernel extension
Checking my log files I could see
kernel[0]: failed to detach com.ncp-e.vpn.driver.ncplbmac filter (err=22)
logged after disconnecting my forticlient or a pptp session
deleted the com.ncp-e.vpn.driver.ncplbmac kernel extension and that sorted it.

VPN (PPTP) Authentication Failed
Hi,
I am trying to Connect to my work network. Work uses a Secure Computing SG560.
The setup at work on the SG560 is as follows:
PPTP VPN Server
Authentication Scheme: Weakly Encrypted Authentication (CHAP)
Encryption: Strong Encryption (MPPE 128 Bit)
On my mac, I have setup a new VPN (PPTP) Connection
Given it the Internet Address
My Account Name
Encryption Auto (And tried Maximum)
Authentication Settings is password with my password set on the SG560.
Pressing Connection I get a prompt saying Authentication failed
In my console I have this (obviously some settings omitted)
6/12/10 06/12/10 - 9:06:48 PM pppd[1825] pppd 2.4.2 (Apple version 412.3) started by wt9bind, uid 501

The only way to get this working is to change the Authentication Scheme in the SG560 to No Auth
If I do this, it connects perfectly with the following:

Now obviously running no auth is totally unacceptable.
The options in the SG560 for Authentication Scheme is:
PAP
CHAP
MS-CHAP
MS-CHAPV2
Required Encryption:
No Encryption
Basic Encryption MPPE 40Bit
Strong Encryption MPPE 128Bit
Can somebody tell me why my client on my mac will not connect as soon as the encryption level is changed on the SG560? It works perfectly from Windows.
ThanksCan anybody help me on this?

Tiger VPN (PPTP) connection issues
Hello everyone.
I'm having major issues trying to connect to office VPN from home; hoping someone can point me in the right direction. (And my profound apologies in advance for the long post -- just trying make sure to include enough detail to debug whatever might be happening)
At the office we have a 3Com OfficeConnect VPN Firewall sitting in front of a Microsoft 2003 Exchange server. (3Com product page for this VPN box is http://www.3com.com/products/en_US/detail.jsp?tab=features&sku=3CR870-95&pathtyp e=purchase). Home connection is a Linksys WRT54GL wireless router in front of a broadband cable modem. PPTP pass-through is enabled in the router config.
At home I have a WinXP-SP2 laptop and my G4 Powerbook (OS 10.4.7) sitting side-by-side. From the XP laptop, I can get into the VPN using XP's built-in client without any problems. The DNS lookup and authentication steps take about 2-3 seconds combined. Once the connection is established, both external sites (cnn.com) and internal sites (intranet.companyname.local) load in a browser window without any appreciable delay. I can also access Windows shared drives on the internal network without problems, including large (10's of MB or more) file copies to/from the XP laptop's HD.
On the Powerbook, using Tiger's built-in VPN client, I can connect OK (though the authentication step takes a bit longer, about 4-5 seconds), but after that, almost nothing works. I can ping the internal DNS server, but after a few pings with reasonable delays (~15 millisecond range), the round-trip times suddenly jump to handfuls of seconds. In the browser, trying to load an internal webpage (http://intranet.companyname.local) times out before anything shows up on screen. In Finder, using Go>Connect to Server... very slowly establishes the connection (~10-15 seconds or longer), and sometimes opens a Finder window... but then invariably times out. I have never once had the connection remain stable enough to transfer so much as a single file from the shared volume onto the Powerbook's Desktop before it times out and disconnects.
On the XP machine, relevant(?) VPN config settings are:
require secured password
require data encryption (disconnect if none)
PPTP VPN
LCP extensions enabled
software compression enabled
multi-link negotiation for single link connections DISABLED
server type = PPP
transports = TCP/IP
authentication = MS CHAP
encryption = MPPE 128
compression = none
PPP multilink framing = off
and, once the VPN connection is established, parameters are (from "ipcofig /all"):

Approximate round trip times in milli-seconds:

On the Powerbook, I have a VPN (PPTP) connection set up with "Send all traffic over VPN connection" unchecked. In the Network panel of System Preferences, I have tried manually adding (and removing) "local, (companyname).local" in the Search Domains line, and manually adding (and removing) the IPs of our internal DNS servers (172.16.0.5, 172.16.0.11) under the TCP/IP tab. Proxies are turned off in all cases.
With those settings, the relevant(?) parts of running "ifconfig" from a Terminal window after starting the VPN are as follows:

The problem is that despite this apparently successful negotiation, the VPN connection doesn't really work. If I type "intranet" into the browser URL bar, it doesn't pick it up as "intranet.companyname.local" and instead treats this as a search query, which it passes to google... which times out. If I type "intranet.companyname.local" into the URL bar instead, it appears to do the DNS lookup correctly... but then times out again.
Ping times look like this at first:

OK, enough for now. Can anyone spot what I might be doing wrong, and/or suggest something to try to remedy this? If there is any additional logging/debug info that would be useful, please ask and I will track it down.
Thanks very much in advance!!! /HJProblem not entirely solved, but mostly working now. It turns out the issue was with the 3Com OfficeConnect VPN box. It was causing all sorts of headaches and had to be manually power cycled at least once a week, so we ditched it and got a Linux-based Firewall/VPN appliance (http://www.ingate.com/ingate_vpn.php).
Now I can connect and mount Windows drives via SMB (both the command line and the Finder's "Connect to Server" approach seem to work). Performance still exhibits annoying lags at random times, and occasionally the VPN connection disconnects for no good reason, but at least I can get at my files from home. The other issues -- such as being able to resolve "xxx.yyy.local" addresses in the browser by making sure I hit the internal DNS server before any external ones -- all seem to be network configuration issues on my end.
In short, my guess is that the 3Com box was causing issues with some low-level timing parameters or other related settings in how the VPN connection was being established. I was just starting to teach myself about ARP tables, NTLMv2 authentication, and the like when we replaced it with the new firewall.
Hope this helps.

Any suggestions? TIAVPN has been a continuing issue in or organisation. There could be more than one issue problem causing the issues we have, however we have found that our Netgear router appears to have issues. After a bit of research on other forums I found other people who had flagged other Netgear routers as having similar issues and that VPN connections could be reestablished buy turning on and off settings with in the control panel for the router. Doing so jogs it working again for no apparent reason, even when the resulting settings are exactly the same as before.
It is because of this reason and other issues I have had with other Netgear routers that I have decided that I cant fully fix our issues with VPN until we have replaced our router with something more suitable. -
[Solved] VPN - PPTP + OpenVPN not working
Hi everyone,
I've got a problem with the configuration of my new VPN. Everytime I try to connect to my commercial VPN-Server (to get access to BBC, Hulu etc.), I get the error
# openvpn test.conf
TLS Error: TLS key negotiation failed to occur within 60 seconds (check your network connectivity)

Fri May 7 08:58:13 2010 us=944416 TCP/UDP: Closing socket
Something similar is happening if I use PPTP with kvpnc

OpenVPN client.conf (mostly from the Arch-Wiki)

proto udp
remote openvpn.blackVPN.co.uk 1194
resolv-retry infinite
nobind
persist-tun
comp-lzo

auth-user-pass passwd
ca ca.crt
What really kills me is, that both options (OpenVPN + PPTP) work under a parallel installed Windows Vista (PPTP) / and a Windows 7 virtual machine under virtualbox running as guest in my Arch system (installed OpenVPN). So I can eliminate any problems with my router and the server. I figured, that I might be missing some configuration options for my static IP-configuration, but even going back to DHCP doesn't take me any further. The problem remains.
I hope someone might have a clue for me. I'd really appreciate it.
Thx in advance,
Ronnie

In the meantime, I think, I made some progress with PPTP instead. I checked the wiki, configured pptp with pptpsetup and got it working, I guess. In some way. The only problem is, that I might be connected over ppp0, but all my traffic is still going the wrong way, because my (outside) IP is still the same (which I check with http://www.wieistmeineip.de/). I think, I'm missing something here, sorry, network stuff always gives me headaches and I don't see the obvious :

So, now I am in a fix. The server is at 150km distance and is headless. Without VPN, I cannot share its screen nor do anything with WorkGroup manager. I can log in with ssh and I can run Server Admin at a distance.
Any tips what I can do (from the command line) to fix this? For instance, can I do a repair permissions from the command line?Installing 10.5.2 on both sides made it work twice. I had a working VPN again after upgrading both sides. But a second time around it failed. I rebooted both sides and it worked again, once.
Now, whatever I do, I fail to get authenticated again so i am back to square one.
I wonder if this could help me out:

Slow VPN PPTP Transfer Speeds vs. Windows XP
I recently switched my father to a new unibody MacBook after years of Windows XP heartache. He uses a VPN (PPTP) connection to access files on the Windows 2003 server at work.
*On the Mac (10.5.5), the file transfer speed over VPN is so slow that it is unusable.* Leopard can connect to the SMB server easily enough but clicking on a volume shows nothing until, after a 2-3 minute wait, the file list finally populates. The old Windows XP machine loads the volumes far quicker and is noticeably faster.
We are using the same credentials and settings as on the old machine, but nothing we do will speed up the connection so that it is actually usable.
Any thoughts or suggestions? At this stage I am extremely disappointed in the Mac's ability to integrate with enterprise. I was so sure the transition would be seamless but Leopard is making basic tasks much more difficult. It's egg on my face!
Help would be much appreciated!
Thanks, jd.
P.S. My apologies if this has already been discussed. Searching didn't give me many relevant results...Hi Joe,
College networks can have a lot of unusual security monitoring systems in place, so it's conceivable that they limit non-PC speed, but as you said, you've checked that.
There is a known issue with some Gigabit Ethernet capable Macintosh systems and some switches. This problem can be fixed by software configuration, so it's possible Windows automatically does it, but MacOS doesn't. Have a look at the instructions specified in this Apple article and see if it helps: http://docs.info.apple.com/article.html?artnum=303660 -

i use a macbook pro which came with facetime i have an iphone 4S as well. whenever i use the wireless on my iphone i can facetime with ease however when i use the same wireless for my mac to facetime the call always gets disconnected.
To use factime on your Mac, I believe you will need to use your email address to do so instead of your wireless number. Since you can't make calls on the Mac.

"Back to My Mac is turned on, your VPN connection cannot be established"?
Hi,
I searched for this recurring notice that I am getting " Because Back to My Mac is turned on, your VPN connection cannot be established", and came up with this thread: http://discussions.info.apple.com/message.jspa?messageID=8436720
However, I am not trying to establish a VPN when I get this message (and don't have one AFAIK).
Any idea what might be causing this message? I can't seem to figure out what triggers it, it just seems to pop up every hour or so. iChat is the only thing I have been using recently that seems to
Is there any way to discover what VPNs my laptop has set up? I don't have any additional software that is specific to VPNs, so it would have to be something already built into the OS. Does the Transmission application create a VPN? That is the only thing I can think of.
Any other ideas on what might be causing this message?
Your help is appreciated!
A.If you have a VPN installed (by mistake?) you should be able to go to your System Prefs > Network and see the VPN listed in the left hand column along with Aiport and Ethernet. You can un-install by using the minus button at the bottom of the column.
The link provided shows you how to install a VPN client with screen shots, including one of this Network Prefs screen and what a VPN client looks like.

My VPN keeps disconnecting after downloaded iOS 8. How do I fix this?
my VPN keeps disconnecting after I have downloaded iOS 8 on my iPad. Why is this happening? How can I fix it?
I am having similar issues. IPad mini ios 8.0.2. VPN connection will drop unexpectedly. Actually, it drops coincide with an active application that uses a lot of memory. Such as a web browser. I can 100% replicate behavior by connecting VPN, going to Safari, and opening Facebook. If I don't use an app that is memory-intensive, VPN stays connected indefinitely.

Slow screensaver unlock after VPN is disconnected
We have a couple of full time remote users on 10.5.7 using mobile accounts and they have been reporting a problem where once they disconnect from a VPN session unlocking their screensaver can take a couple of tries and the computer will spin it's wheel for a couple of minutes.
We used to have this problem in the past when the internal hostname we use for our OD server used to resolve from outside our network. We removed the OD hostname from the external DNS and that fixed that problem.
I'm assuming the problem now is that the client now has a valid DNS cache for the OD master via the VPN and once the VPN is disconnected it's still trying to connect to that IP and hence timing out.
Is that assumption correct? And if so how can we fix it as I'd imagine it should be a common problem but couldn't find it after searching here or googling it. And if the assumption is incorrect any pointers on the what and how?
thanksI seem to have found a work-around. There is probably a neater way of doing this but here goes.
Here is my setup:
Airport Wireless to my home router
PPP VPN connection to my office windows network
3G connection via mobile phone
My aim was to be able to connect to my office network via wireless at home or via my cellular data connection, but continue to route all non-work traffic via the main connection (wireless/3G).
The #1 problem I had once I connected to my office VPN on either wireless or 3G, was that DNS lookups to general internet sites took forever. So to get around this, I created TWO VPN connections to my office network in Network Preferences and in both connections I made sure the option to send all traffic over VPN was left UNCHECKED.
The first connection I then designated for use when connecting wirelessly at home. Here I manually added the IP address of my home router as a DNS entry.
The second connection I did the same by adding a new DNS entry, except here I used the DNS server of my cellular data connection, in this case T-Mobile UK.
When connecting to my office network I just use either of the above connections depending on whether I am connecting wirelessly at home or via my mobile phone.
It seems a bit long winded I grant you, but after literally months of trying to resolve this annoying problem, this appears to be the only fix that works.
The downfall of this would be that DNS resolution to any servers on your office network might not work, but that isn't a problem for me since I manually add any servers I use at work to my local hosts file. This negates any need for DNS lookups and actually speeds up access to my work servers.
In amongst this I did several reboots, so you give your machine a reboot once you've completed the above steps, just in case.
The 3G connection won't work for you if your provider changes the DNS server every time you connect, but this is unlikely.
If anyone's got any comments, I'd love to hear them.
Cheers

Keine Verbindung ins VPN (PPTP) seit 10.7.3
Hallo.
Seit Update auf 10.7.3 komme ich mit dem MacBook nicht mehr ins VPN (PPTP) rein. Der Verbindungsaufbau wird sofort abgebrochen. Die Seite http://support.apple.com/kb/HT4748 kenne ich schon und hilft mir rein gar nicht weiter.
Meinen iMac hab ich immer auf gleichem Stand wie das MacBook was die Software betrifft. Mit dem iMac komme ich ins VPN, mit dem Macbook nicht. Ich habe bereits alle Einstellungen überprüft, neu vorgenommen etc. und kann einfach nicht das Problem finden. Im Internet habe ich gelesen, dass einige Leute das gleiche Problem haben aber bisher keine Lösungsansätze.
Kann mir jemand weiterhelfen?
Viele Grüße
RosiIf you have access to latest developer builds of 10.7.3..
Replace /usr/sbin/vpnd in your 10.7.2 server with the same file from 10.7.3 build.
This resolves the CCP issue -
Vista PPTP disconnect crashes Time Capsule
PPTP VPN pass-through on Time Capsule's Wi-Fi Airport connection works well when using Microsoft XP, Mac OS X 10.5.2, and the iPhone PPTP VPN client. It connects fine using Vista but, on disconnecting Vista's PPTP client, Time Capsule crashes and reboots. This issue is consistently repeatable.
The Time Capsule was purchased last week with Firmware Version 7.3.1 and my Airport utility has been updated to version 5.3.1 on both the Vista and OS X machines. Does anybody know of a fix for this issue?Same problem even after upgrading to 7.3.2.

Native VPN PPTP client won't stay connected
Folks,
I have setup my VPN using the Mac OSX native PPTP VPN client to connect to my client's work network. However, it appears that it won't stay connected. I have been searching the net for answers. I can't find a definitely one. Does anyone have the same issue where you can share your solution with me please?
To be more specific, I have a Windows XP laptop and a Mac. I connect to the same VPN on both machines. The Windows XP laptop will stay connected while the mac will drop the connection randomly. This is particularly true when my Mac went to sleep and then wake up.
In my PPTP VPN setup, I have already uncheck the option "Disconnect when user logs out" option in the Advance setting.
Also, this appears to be Mac OSX issue because I have another client where I can use the Cisco AnyWhere VPN client to connect and the connection stays connected all the time including the time when my Mac went into sleep mode.
My mac is the new MacBook Pro with Retina display running Mountain Lion (The original OS is Lion and then upgraded to Mountain Lion) and I am using the Thunderbolt to Ethernet adapter to connect to my wire network. It doesn't make much difference even if I switch over to a Wireless connection. In both cases, the VPN just won't stay connected.
Can someone point me to the right direction as to where I can trouble shoot this please? Thanks.Thanks sberman. In the article, it mentions something about VPN on Demand, where in the setup do you see this setup? I am in the Network setup area and I am not finding this. Also, if I turn on the "Use verbose loggin", where is the log file? Is it still the /var/log/ppp.log file
Also, one more thing, my main ethernet connection setting does not include a proxy setting. But my VPN setup includes a proxy setting. Do you think that I may need to update the main ethernet setting to add the proxy setup to it as well? But I don't want to keep updating the main ethernet connection network setting to switch between proxy or not. Any suggestion will be welcome.
Thanks.
