Connman cannot connect over pptp

I was trying to set up a pptp VPN with connman. However, even after creating a config file in /var/lib/connman-vpn, I seem to not be able to connect to the vpn. The file (/var/lib/connman-vpn/kuins.config) is:
[global]
Name = KUINS
Description = Connect to the VPN
[provider_PPTP]
Type = PPTP
Name = Connection to KUINS using pptp
Host = pptp0.kuins.kyoto-u.ac.jp
PPTP.User = xxx
PPTP.Password = "xyz"
PPPD.RequireMPPE128
PPPD.NoDeflate
PPPD.NoBSDComp
This particular PPTP VPN does not require a domain, so I did not add that option. I can confirm that I can connect to it using my credentials and the instructions given on this wiki page.
Upon running:
# connmanctl
connmanctl> vpnagent on
VPN Agent registered
connmanctl> vpnconnections
connmanctl>exit
There is no output to vpnconnections. I would like to use connman over netctl as it provides much better speed for dhcp ethernet for me, however, if it is necessary for me to be able to connect to this PPTP VPN. Unfortunately, there is no other way (e.g. OpenVPN) for me to connect to it.
Also, unfortunately, it seems that I cannot use pon and poff in order to enable/disable this VPN if I use connman.
$ sudo pon kuins
$ sudo ip route add default dev ppp0
RTNETLINK answers: File exists
Unfortunately, it seems not to be, as traffic certainly does not get routed through this VPN. My organisation requires that I use this VPN to connect to anything over port 80, and if that is not happening, I simply cannot connect. Which is exactly what happens here.
Any ideas as to what to do?

I have destroyed and re-added the OD replica but that did not seem to help

I suspect the problem is to do with Kerberos and in relation to this server being an OD Replica.
I would really appreciate anyone's insight into this.
Thanks

I have the same problem although I upgraded from Lion Server to Mountain Lion Server. The error appears to go hand in hand with this error.
userInit: CFPreferences: user home directory for user kCFPreferencesCurrentUser at /Network/Servers/fullyqualifieddomainname/Users/user is unavailable. User domains will be volatile.
I've read a number of things to try. A lot of people point to DNS being a problem, but I'm confident this is correct in my environment.

Cannot connect to PPTP VPN

am working on setting up a VPN on my MS Directaccess server. technically the vpn is up and running and working already. it is using a certificate that is issues to the DA server by the DA server. My domain joined PC's connect fine. I can also connect a non domain joined machine if I import that certificate into the PC. However I cannot connect any OSX clients or my android phone. We have opened up port 1723 on the firewall. I have tried to connect from my home and from another businesss locally to make sure it wasnt just my home router causing the issue for some reason.
I get this in the osx console log (I replaced the external IP with 1.1.1.1 for posting this online)
3/19/14 7:55:21 AM pppd[6282] pppd 2.4.2 (Apple version 412.5.70) started by admin, uid 501

On the directaccess server I get this in the event viewer everytime the OSX client tries to connect. This at least proves that I can at least connect to the server from the outside.
Event 20209, RasMan
A connection between the VPN server and the VPN client 24.97.100.42 has been established, but the VPN connection cannot be completed. The most common cause for this is that a firewall or router between the VPN server and the VPN client is not configured to allow Generic Routing Encapsulation (GRE) packets (protocol 47).
Im assuming this isnt a port or protocol issus since I can connect via my non domain joined Windows PC. Im out of ideas as to what I can do next

Here is a snapshot of my console

Single account on imac can see but cannot connect over network

This one is driving me crazy:
As of this morning I cannot connect to other computers in our network. Using other accounts on the same imac is no problem, but mine simply refuses.
I can see the rest of the network, connect to the internet, print, etc., but if I try to actually connect to another machine I get the error that it cannot find the original item (the error is in Dutch so I cannot give the litteral version)
Network, firewall and sharing settings seem to be the same as the other, working, accounts as far as I can tell.

OK, we found the problem. my permissions were screwed up...

I'm getting a PDP authentication failure message and cannot connect over 3G. Help?!

A few days ago I suddenly started getting an error message when trying to connect to the internet over 3G. "Could not activate cellular data network. PDP authentication failure"
I am in Germany, on Telekom. Have called Telekom customer service and went to the Telekom retail store. Neither could figure out the problem and advised I do a factory restore on the iphone via iTunes. I did that and am still getting the error message.
The only weird thing that happened before the error started showing up is I had called Telekom the night before to add a U.S. data roaming package to my phone plan for an upcoming stateside trip. They told me to text "W2S" to 7277 in order to add the U.S. data roaming plan. I did that, and the next morning this error started popping up. Don't know if that is related or coincidence.
I am traveling to the states in a few days and would really like to get this cleared up. The only option Telekom has left for me is to mail my phone in to Apple. :-(

If I may ask, what country are you from?
To note, what you see is just not possible from a radio communication level, you're the first I've ever seen with this problem. (see photo and footnote below)
Since you said the Carrier option is available, can you go to it, turn off automatic and see what networks show? Normally it you will see At&t and T-mobile, however, if you see Sprint, you will need to go talk to Apple.
But if T-mobile does show, select it and see if your phone connects.
If not, remove the SIM card reboot the phone and try again.
I'm sorry about not being clear about the phone number, while connected to the Verizon network, is the phone number showing your T-mobile one or is it something different?
For reference,
Normally, what you will see in the status bar when on the Verizon network when not on 3G/LTE is the 1X symbol.
GPRS is a completely different communication type from 1X and Verizon doesn't support it. If you visit a Verizon store (or T-mobile) the staff will probably be surprised and confused about what your phone is showing.

Cannot connect over same network

Imac (Lion), macbook air (mtn lion), same network, different email addresses. I send a face time message from the imac to the mac book air and both ring but there is no option to open the face time message on the receiving device. Face Time is working with devices off of this network. Thanks very much for your assistance.

Please see the following post
http://discussions.apple.com/thread.jspa?threadID=250220&tstart=30
You can see that there are many ways to do this but my suggestion is:-
1. Syc your iPod with your iTunes with the PC
2. Download the 3rd party software called "iPodRip"
3. Using iPodRip to copy the music from your iPod to your iTunes with your Mac.

Why does the YouTube app say "Cannot Connect to YouTube" over Wifi or 3G?

Hi, everyone.
When I open the YouTube app with Wifi or 3G, it says "Cannot Connect to YouTube." I've browse a few sites, and the number one response is to reset the router. I tried resetting the router (Latest Apple AirPort Extreme) to factory default and Restoring the iPad 2 from Backup. I would believe the router issue to be plausible if 3G worked. Since YouTube doesn't work over 3G, I don't believe the router is the issue.
Does anyone have any ideas?
Thank you.

Me too, ipad mini can't get YouTube app to function via the official app and the same error message," ...tap to retry", but to no avail. The app launches but it will not allow me to sign in. The drop arrow just tilts up and down and ...nothing. I can still access YouTube through Safari browser but strange, I can't find a solution to the app not opening or being able to sign in on either ipad mini or phone even though they are up to date apps.

Server cannot be connected over ssl

Installed self-signed certificate on the Messaging Server. And started up the messaing server with ssl.
"netstat " shows port 993 is idle. But seems cannot connect to it .
The messaing server was running on a standalone machine, not network connective.
Does ssl require connections over the network?
Thanks!

Installed self-signed certificate on the Messaging
Server. And started up the messaing server with ssl."started the messaging serve with ssl". Means what?
Did you make the configutil settings to turn any of the ssl functions on?
Did you edit the sslpassword.conf file to add the password for the certificate database?
Did you make a typo? The default name of the cert is "Server-Cert". "server-cert" is not the same, as it's case sensitive.
Did you examine any of the logs and see errors on the restart?
I don't even know what version Messaging you're running. Frankly, you've a whole bunch of homework to do before I can be much help.

Got a new computer, just downloaded i-tunes and such all over again. Now wanting to watch a movie and Apple TV is saying "cannot connect to internet"

We're trying to watch a movie using our Apple TV. It is saying "cannot connect to internet?" WE thought it was because we just got a new computer, so i went through the process of downloating i-tunes all over again...yet we still have the problem. ??? PLease help

Linda
What exactly has changed?
Just the computer, other things?
More information on your actual setup is needed - Particularly how things are connected on the local network and to each other.
In theory the new computer should not affect Apple TV's ability to rent and play a movie if the rental was made on the AppleTV itself. The problem may have nothing to do with the new computer unless changes have been made on the router to let it connect and it's caused AppleTv to disconnect, or the PC has been assigned the AppleTV's IP address which is no longer available to AppleTV hence it thinks it's lost connection.
Try powering off the router, restarting and see if the AppleTV internet connection returns. Restart AppleTv too if needed. Check any ethernet cable connections or wi-fi settings on AppleTV if it doesn't re-establish the internet connection. By the way an ethernet cable plugged into AppleTV will disconnect it's wi-fi connections.

Cannot connect to Verizon email over Time Warner wifi

I cannot connect my iPad or my Android phone over my Time Warner wi fi. Both work fine over Verizon wi fi, and my phone is fine over the NYC 4G network ((my iPad is wifi only). Can you help?

Make sure you are using the correct NEWER Verizon servers. Are using port 465 for SMTP and port 995 for POP. Are using SSL connection, and authentication with CLEAR password. http://verizon.com/emailsettings
Its possible the problem is with Time Warner or that they need to request that they be whielisted http://my.verizon.com/micro/whitelist/RequestForm.aspx?id=isp . You can request that your home ISP be whitelisted http://my.verizon.com/whitelist but your IP might change over time.

Client Computer cannot connect to server over internet (VPN)

Hello Guys,
I am setting up a windows server 2012 Data centre for business purpose. I have installed & configured server with AD DC, DNS, DHCP, IIS, NPS, Routing etc.. I am able to connect client computers which is on the same domain to the server through same router.
VPN also work fine. But if I try to connect to the server via VPN through a different internet connection it won't connect. Can some one please tell me what I am doing wrong.
My Network Confg is,
DHCP IP ADDRESS FROM ISP
DHCP Disables Router, (Tried with enable)
Have my own website domain which is not linked with the server.
NAT not configured.
Thanks in Advance
Emmanual.

Hi Emmanual,
Thank you for posting in Windows Server Forum.
Can you ping to the remote server after connecting through VPN?
Did you find any specific error\event id for your case?
What’s your client OS version?
If you are not getting ping successfully then seems there is connection issue through VPN. So for this you can initially check the connection setting with following article.
You Cannot Connect to the Internet After You Connect to a VPN Server
http://support.microsoft.com/kb/317025
There are several reason as client is not getting remotely connected to server. In addition you can checl following article.
Enabling remote client access over a VPN connection

Hope it helps!

Cannot connect to ASDM on ASA 5505 over https

Problem: Cannot connect to ASDM on ASA 5505 when vlan1 network is changed from the factory default.
Hi all. I am just getting started on a new ASA 5505, working it in a test lab environment. I ran thru the initial setup wizard. During that time I specified a name for Vlan1 (changed from 'inside' to 'INTR-NET'), modified the Vlan1 IP address to use DHCP, and then populated the Device Config Access table with entries corresponding to the entire Class B network here on the local intranet. I don't recall if the factory-default network was already populated, but if it wasn't I added it as 192.168.1.0/255.255.255.0
I then saved the config, and verified that the ASA got a dhcp address using the RS-232 console. I then reconfigured the laptop I have plugged into port 0/1 with it's normal address on the intranet and discovered that I couldn't reconnect to ASDM. The ASDM client times out, and a web browser opened to https://(ASA5505's dhcp addr) fails as well.
I then used the console to add another http IP address matching the specific IP address (xxx.240.113.129/255.255.255.255) which the laptop is set for, to the list of permissible admin connections, but saw no difference.
This issue is much the same as was reported in this prior forum posting:
http://forums.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Security&topic=General&topicID=.ee6e1f8&CommCmd=MB%3Fcmd%3Dpass_through%26location%3Doutline%40%5E1%40%40.2cc16cb8/4
EXCEPT that I was already aware the admin IP address(es) needed to be registered to enable access via SSH/Telnet/HTTPS.
And, I did that step, but it is not working. I have tried adding various combinations of network ranges in the device config access list, including the specific subnet that the lab's dhcp server assigned to the ASA 5505 (xxx.240.112.0/255.255.254.0), but there is no difference. I can traceroute to the laptop and ping the Vlan1 interface from the laptop, but the https ASDM (and ssh connections too) are not successful. This is very frustrating.
The device is brand new, I see that upon boot it loads asa724-k8.bin, and the software banner says Cisco Adaptive Security Appliance Software Version 7.2(4)
Note also that, from the RS-232 console, if I reset the IP address to the static, factory default (192.168.1.1) and manually config my laptop on the same subnet, then ASDM makes the connection. Just like out of the box. But when I put it back onto our intranet and verify the DHCP lease, then ASDM is a no go.
Can you think of what I've missed?

Good question. Let me add that info plus related Vlan config details:
