Created attachment 358024 [details]
log of vpn connection success, routes added, and ppp device created
Created attachment 358025 [details]
ppp peers file used for successful connection.
I connect manually using "sudo pppd call uiuc"
I found a solution to this problem: Using gconf-editor edit the VPN connection under system->Networking->connections, unset the "require-mppe" key, add a new key "require-mppe-128", type string, value "yes". VPN works fine after that. This prevents the 40-bit key from being attempted for VPNs which require only the 128-bit key. I believe this is fixed upstream by: 418b3c8f953e516df049c4c764e3467c0a19512a (master) 0c39c37fe4a395529bb7025027f60931152fd6ac (master) 5661093ca9a58f373a2e432871a7322352a2bdeb (0.7.x) 814bccb6d7d103b1e0ec3338c3140cb43a39b91d (0.7.x) It's also bugzilla.gnome.org #596762 for the first one, and lp:371402 for the second. I'll be posting F11 updates soon for all the VPN plugins. Tagged and ready to build when NM 0.7.2 hits f11-updates. *** Bug 544691 has been marked as a duplicate of this bug. *** NetworkManager-openconnect-0.7.2-1.fc11,NetworkManager-pptp-0.7.2-1.fc11,NetworkManager-openvpn-0.7.2-1.fc11,NetworkManager-vpnc-0.7.2-1.fc11 has been submitted as an update for Fedora 11. http://admin.fedoraproject.org/updates/NetworkManager-openconnect-0.7.2-1.fc11,NetworkManager-pptp-0.7.2-1.fc11,NetworkManager-openvpn-0.7.2-1.fc11,NetworkManager-vpnc-0.7.2-1.fc11 NetworkManager-openconnect-0.7.2-1.fc11, NetworkManager-pptp-0.7.2-1.fc11, NetworkManager-openvpn-0.7.2-1.fc11, NetworkManager-vpnc-0.7.2-1.fc11 has been pushed to the Fedora 11 testing repository.

Created attachment 358023 [details] log of vpn connection failure and one route that gets set. Description of problem: NetworkManager-pptp-0.7.0.99-1.fc11.i586 will not connect my VPN I believe because it is not disabling 40-bit MPPE. Instructions for my VPN specifically state that 40-bit MPPE must be disabled. The pptp plugin edit options allow the following options for security: All Available (default), 128-bit, and 40 bit. I set it to 128-bit, but when I try to connect, I see in the log files that it doesn't seem to disable 40-bit. If I try to connect manually by calling pppd on the command line and setting the require-mppe-128 option, I can connect fine. Version-Release number of selected component (if applicable): NetworkManager-pptp-0.7.0.99-1.fc11.i586 How reproducible: always Steps to Reproduce: 1. Set security to 128-bit 2. activate vpn connection Actual results: Authentication seems to work OK, but the connection can not complete. Expected results: Connection completes, ppp device is assigned and IP address, routes are set and communications with VPN are established. Additional info: I'll include log files of connection failure with NetworkManager, connection success with manual call of pppd, and /etc/ppp/peers/uiuc file.
