GNOME Bugzilla – Bug 555626
[enh] static IP but DNS via DHCP
Last modified: 2020-11-12 14:27:35 UTC
NetworkManager 0.7 (SVN) does not provide a way for configuring a static IP for an interface, but get the DNS, gateway, time servers etc. from DHCP. This is a commonly found option in other operating systems (e.g. Mac OS X) where a user can opt for 'DHCP with manual address'. Such a configuration is required in cases where a static IP is needed, but cannot be configured by the DHCP server (viz. several Linksys home gateways whose software lacks static allocation functionality), but where all other data pertaining to the connection should be retrieved via DHCP.
I am not sure how common this is, but when designing the new nm-applet we should look at this.
This is actually an applet limitation; NM should support this OK, but this case simply wasn't known at the time.
Created attachment 123930 [details] Screen listing the connection profile for mobile provider
I can give a use case for this problem: I am using a mobile broadband modem provided to me by my ISP: Tata Indicom (PlugToSurf). There is a connection profile for this ISP already available in the applet setup wizard. Please refer attachment id =123930 But the Network manager daemon fails to retrieve data from the USB CDMA Modem provided to me with the following output. Dec 2 20:26:47 xendor NetworkManager: <debug> [1228229807.892297] probe_modem(): Couldn't get caps I think it is because the modem device I am using is not providing a well formed reply. In such cases which do happen the nm-applet should allow the user a manual override to do connection setup of device manually through PPP. I believe in the 0.7 the ability to do this manually has been removed. Programs like WVDial meanwhile works perfectly with the device but unfortunately doesnot integrate with network manager. If the trend is to make NetworkManager the defacto network setup and management tool, it is mandatory that the program handle dialup schemas perfectly.

Hmm, this doesn't seem related to the bug report above. The report above is about IP configuration of the interface itself, not about mobile broadband problems. > Dec 2 20:26:47 xendor NetworkManager: <debug> [1228229807.892297] > probe_modem(): Couldn't get caps Modem probing in NM is a custom Ubuntu patch and not in NetworkManager itself. Please file a bug in launchpad for your problem.
bugzilla.gnome.org is being shut down in favor of a GitLab instance. We are closing all old bug reports and feature requests in GNOME Bugzilla which have not seen updates for a long time. If you still use NetworkManager and if you still see this bug / want this feature in a recent and supported version of NetworkManager, then please feel free to report it at https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/issues/ Thank you for creating this report and we are sorry it could not be implemented (workforce and time is unfortunately limited).
