I remember seeing a post about this recently, but I can't seem to find it... Anyhow:

Having set up a SIP account for an internal SIP server on my N900, it was quite irritating to have to constantly disable it after leaving WiFi to stop the messages about not being able to connect. So, I wrote a quick script which allows mapping of IM accounts to connections.

I've hardly tested it, but it works for me, and it's a kludgey but good enough hack until this feature (hopefully) gets integrated.

The script:

Code:

#!/usr/bin/env python
import conic
import dbus
import gobject
import dbus.glib

accounts = {
"account": ["connection1", "connection2"],

}

loop = gobject.MainLoop()
bus = dbus.SessionBus()


def state(account, new):
    accountd = bus.get_object('org.freedesktop.Telepathy.AccountManager', account)
    iface = dbus.Interface(accountd, 'org.freedesktop.DBus.Properties')
    iface.Set("org.freedesktop.Telepathy.Account", "Enabled", new)

def connection_cb(connection, event):
    if event.get_status() == conic.STATUS_CONNECTED:
        iap_id = event.get_iap_id()
        for account in accounts:
            state(account, iap_id in accounts[account])

connection = conic.Connection()
connection.connect("connection-event", connection_cb)
connection.set_property("automatic-connection-events", True)

loop.run()

Configuration is simple, change the dictionary "accounts" with whatever details you want.

To list your accounts, use the command

Code:

/usr/bin/dbus-send --type=method_call --print-reply --dest=org.freedesktop.Telepathy.AccountManager /org/freedesktop/Telepathy/AccountManager org.freedesktop.DBus.Properties.Get string:org.freedesktop.Telepathy.AccountManager string:ValidAccounts

And for the connections, either use the name of the connection (for GPRS / 3G) or the unique identifier for WLAN. To get the identifier, run the following bit of Python:

Code:

import conic

iaps = conic.Connection().get_all_iaps()
for iap in iaps:
    print "%s - %s" % (iap.get_name(), iap.get_id())

For example, for me, I'd use the following to have my GMail account only enabled on WiFi:

Code:

accounts = {
"/org/freedesktop/Telepathy/Account/gabble/jabber/florenzi_40gmail_2ecom0": ["ffcd0203-51ae-4bde-9622-d0256937b11b"],
}

And then fire it up in the Terminal as a normal user. You need python-dbus and python-conic installed.

Hope this helps some people out, if people could also test it and report back that would be great. It shouldn't really take too long to write a simple GUI and package this up properly. Also, other things, like only on WiFi / only on GPRS should be quite easy to implement.

cb22, thanks a lot for that. I'll try your solution as soon as I can. The "only on WiFi/ only on GPRS" idea seems really useful. Also, when you can, go ahead and package that as a GUI utility. A lot more people will be happier.

I did give it a try, but it doesn't seem to work for me. First I checked my connections and accounts:

Code:

user@n900:~/MyDocs/Dev$ python list-connections.py 
adlnet-14 - 5d2108f0-a1ac-40db-bae0-6c17de4f86e5

Code:

user@n900:~/MyDocs/Dev$ /usr/bin/dbus-send --type=method_call --print-reply --dest=org.freedesktop.Telepathy.AccountManager /org/freedesktop/Telepathy/AccountManager org.freedesktop.DBus.Properties.Get string:org.freedesktop.Telepathy.AccountManager string:ValidAccounts
method return sender=:1.20 -> dest=:1.369 reply_serial=2
   variant       array [
         object path "/org/freedesktop/Telepathy/Account/sofiasip/sip/evad002_40sip_2eipfon_2epl0"
      ]

I just want to connect to that one SIP account while connected to adlnet-14, which is my home WiFi. So I've amended main script by adding:

Code:

accounts = {
"/org/freedesktop/Telepathy/Account/sofiasip/sip/evad002_40sip_2eipfon_2epl0": ["5d2108f0-a1ac-40db-bae0-6c17de4f86e5"],
}

Then I run the script as normal user:

Code:

user@n900:~/MyDocs/Dev$ python im-per-connection.py

And wait... but nothing happens, ie. despite being connected to adlnet-14 network (or manually re-triggering a connection), status for that SIP account doesn't change.

Any suggestions?
