Description of problem: On a default install, there is the Administration->Network, and Administration->Network Device Control. Enabling/disabling devices here is going to screw up NetworkManager (now running by default) pretty badly. Version-Release number of selected component (if applicable): system-config-network-1.5.1
So does ifup/ifdown in a terminal?? What should s-c-control/network do? Kill NM?
Well, ifup/ifdown isn't presented to the user in the normal menus. I'm not sure killing NM is the right answer.
nevertheless, someone could ifup/ifdown from a terminal and NM should not screw up... right?
Ideally no, NM wouldn't screw up, but then people could also add/delete/change routes in the routing table, add/remove/change IP addresses, etc. Should NM handle all those cases too? That's a boatload of code for not a lot of benefit. Either you use NM and don't mess with devices, or you don't use NM and you mess with devices. With NM_CONTROLLED=no though, I'll make NM ignore the ifcfg and the device that is specified by the MAC address in the ifconfig file, so that's the "out". If you have a device that's not controlled by NM, then you should probably be able to ifup/ifdown as much as you want. There are at least a few ways to make ifup/ifdown and NM cooperate: 1) If NM isn't running, do what's done now 2) If NM is running, and the ifcfg isn't NM_CONTROLLED=no, poke NM to activate the connection 3) If NM is running, and the ifcfg is NM_CONTROLLED=no, activate the connection but don't change the default route Thoughts?
Well, need a C-based NM-poker, unless we want to do fire&forget dbus-send. Aside from that, seems reasonable.
I'll sign up to write a C-based poker, just need to know what ifup/ifdown expect from it (ie, what commands it should expect, what return values, etc).
Hm, interfaces that I think would be required: 1) is-network-manager-running/ping 2) bring up interface XXX (either by device name or mac address) 3) bring down interface XXX (either by device name or mac address) #2 and #3 should probably have options to block. For compatibility, auto-ip probably shouldn't be tried if DHCP fails. Specific failure codes we may want to enumerate: - ENODEV - device has no link - configuration failed (DHCP or otherwise)
Ok, this version should not let the user activate/deactivate, if NM_CONTROLLED is set. http://people.fedoraproject.org/~harald/downloads/system-config-network/1.5.91/ what do you think?
What actually sets NM_CONTROLLED? Or is it all done by hand?
s-c-n can set/unset it. Dunno what else does.
Can set/unset,or sets/unsets by default?
_Can_ btw, s-c-n > 1.5.3 honors NM_CONTROLLED=yes (default, if not specified is "no") anaconda really should write this and ask/inform the user about this.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
*** Bug 459017 has been marked as a duplicate of this bug. ***
NM should be fixed also, because it's deafault is 'yes' even thou it's not specified.
> NM should be fixed also ... In the current installations, even after upgrades, service 'network' by default is not running. Which would mean "no network connections" if NM requires an explicit "yes" unless this would be added to a configuration. OTOH NM is still unable to set hostname from IP. If there is some documentation which describes what is really expected all around in this setup then I am not aware of its existence.
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.
