I have been working on making custom changes for Afghanistan deployments; disabling 3G access is one of them. </blockquote><div> Interesting, whenever you have the time I would like to hear the reason behind that decision. I am curious :) </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">As the resolution for this, the permissions for "usr/sbin/modem-manager" have been set to 0000, and the change tested on a f14 image with gnome. Following were the test cases that were carried out : a. Checked if "ps -aux | grep "modem-manager" gave anything. It didn't, as expected. b. Although the option to add a new modem connection via GUI was available through nm-applet; however no connection could actually be instantiated in practise, as expected. I then moved on to checking on dextrose-builds-without-gnome (f11 based) It was found that there is no "/usr/sbin/modem-manager" on dextrose-builds-without-gnome (although "usr/sbin/NetworkManager" was present) </blockquote><div> I think there was no modem-manager integration back in NM 0.7 (the one available for f11). </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> </blockquote><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">So, my queries are :: 1. How does the "Modem Configuration" feature work in dextrose-build-without-gnome? This is important, as additional customization may need to be done to disable all 3G access attempts. </blockquote><div> It is because of NM architecture, at least until version 0.7+, the "settings management" service was implemented inside nm-applet, and since there is no nm-applet in sugar, sugar implements its own "settings management" service (take a look at ...source/sugar/src/jarabe/model/network.py to see the implementation). That implementation uses custom gconf values (different from gnome ones) to store the 3G/GSM setting (note that only stores 1 setting for 3G/GSM). Because of what I just explained, there is no relation between gnome and sugar settings (for 3G/GSM and WIFI). </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">2. Is it possible to have a (3G) modem connection in dextrose-build-without-gnome at all? </blockquote><div> Yes (I just explained why). </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Looking forward to a reply. </blockquote><div> No problem, take a look at <a href="http://wiki.sugarlabs.org/go/Features/3G_Support">http://wiki.sugarlabs.org/go/Features/3G_Support</a> for more detailed information. </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> (Thanks Anish, for pointing me to Martin.)
