Description of problem: I have a wlan0 interface like this: $ /sbin/ifconfig wlan0 wlan0 Link encap:Ethernet HWaddr 00:1D:E0:58:BA:E7 inet addr:192.168.1.101 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21d:e0ff:fe58:bae7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1492 Metric:1 RX packets:37916 errors:0 dropped:0 overruns:0 frame:0 TX packets:35731 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:29619551 (28.2 MiB) TX bytes:5179262 (4.9 MiB) Its MTU is 1492, And I created a pptp vpn by using network manager, I got an interface like this: $ /sbin/ifconfig ppp0 ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.3.8 P-t-P:192.168.3.8 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1496 Metric:1 RX packets:7 errors:0 dropped:0 overruns:0 frame:0 TX packets:7 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:3 RX bytes:100 (100.0 b) TX bytes:94 (94.0 b) Its MTU is 1496, more than the mtu of wlan0, it will cause the ppp0 lost connection after some activities over the pptp network. Version-Release number of selected component (if applicable): NetworkManager-pptp-0.7.0-0.10.svn4027.fc9.i386 pptp-1.7.1-4.fc9.i386 ppp-2.4.4-7.fc9.i386 How reproducible: Always. Steps to Reproduce: Prepare a network interface which has MTU lower than 1500, connecting a pptp server over that network. You'll get a pppX interface which has a MTU of 1496, then after you access big chunk data over the pppX, the pptp connection lost. Actual results: NetworkManager-pptp shall set MTU according to the mtu of the interface who loads it. And another improving feature recommendation is to provide a way to set MTU manually in NM-pptp configuration dialog. Expected results: NM-pptp set the MTU correctly.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
