There seems to be a length check, that is failing?

Works well for me, maybe you are missing some library (libconfig, libreadline, libssl, are required). No need to use another device to register, registration works on this client.

XMPP does not work well in an asynchronous mobile environment

The future of XMPP is looking bleak, particularly now that Google—one of its former champions—has abandoned the standard in favor of their proprietary Hangouts format

maintaining a persistent connection to an XMPP server on a mobile device doesn’t perform very well. It sort of works on Android, but frequent server disconnects, dropped messages, and reduced battery life make it a frustrating experience. It’s not even possible on iOS.

Well I do imagine at least something as simple as "per country" servers, or even .. *gasp* facebook, google, whatsapp, $COMPANY providing their own, federated services. Not only I do imagine that but I also was there when e.g. jabberes.org started, Google Talk appeared, etc.

For iPhone people I've been using IM+ Pro (yes, payware). Note that this client effectively proxies every incoming message because iOS is not multitasking. Which means that all you can on iOS do is to choose your own poison, since messages have to be proxied by Apple's push notification service either way.

For Android at least you have several clients to chose from.

The way to go, according to the comparison in the link, is 'surespot' which is also open source, but real secure and not only wanna-be secure like telegram.

http://surespot.im
https://github.com/surespot

Sorry but Surespot is also centralized garbage. The master key is even hardcoded on the client application, so client is implicitly trusting their server (MITM is possible _by them_). No federation.

True on iOS, Android, and most non-multitasking platforms. Without multitasking there is no way to keep a connection open in the background. Thus the only alternative is to use the platform mandated centralized push service.

I suspect that on Android this may be workaroundable -- ie ensure the system does not kill your service by marking it as a "system" service or similar. On Maemo obviously this is not a problem. There's also no difference in battery use when you use timer coalescing for e.g. keepalives (which Maemo/Sailfish do).

Yet as I read on that document services such as like ChatSecure still manage to interoperate with the Jabber network, which is what I expect from a IM service.

I'm having the same error as michaaa62 and i have check i have all the libs required:
libconfig8, libreadline5 and libssl0.9.8

Can this line mean there is a problem with libconfig?

Great!

Registration successful. Now let's explore the options of the cli client.

in my N900 both libssl0.9.8 and libssl0.9.7 are installed at the same time. is it normal? also libreadline4 and libreadline5 are both installed...no need to remove the oldest versions?

Out of curisity, so what's attracting you to this service, versus, opening an account on any jabber server and using the client that's built-in in _every_ Maemo/Sailfish version released to date?

Sorry for not answering to your questions at the beginning of this thread, I'm quite busy with other stuff atm. Many answers to your initial question were already stated in this thread.

The "trap" I believe, is any form of electronic communication. If you want privacy, your best opt is go out in the forest with your chat partner physically and discuss things off wire. It is more personal anyways.

Until a few days Whatsapp was totally ok for me as everyone (naming standard iOS/Android users) had very easy access to this service = registering with their phone number without an additional registering process... being totally aware that my conversations wouldn't be private in the forementioned sense. BUT they were NOT used in a manner like FB systematically conglomerates user data...

I haven't opened a jabber account despite being aware of the advantages.. Getting a whatsapp account and using it on my n9 just suited my needs.

After recognizing Mark just payed 45 bucks for my trivial but still personal messages/pics/whatever thoughts (as he did for the other 449.999.999 users), this is a totally other setting to cope with.

After reading a lot of stuff 'bout existing IM platforms for mobile devices since Whatsapp sellout, I'm just underlining my statement above...

What I need is this simple application to text and send pics cross-platform without generating questionable data agglomeration for a huge corporation as mentioned before.

So bump again for a Telegram Harmattan client.. and if there was a similar sellout it would just generate a similar alternative that is at least not worse than the predecessor.

There are applications that even might need the lower version!

You could test if you could remove the lower version

Code:

sudo gainroot
apt-get purge -s libssl0.9.7
apt-get purge -s libreadline4

The -s switch simulates the removal of a package to test, what packages might get removed as well.

Read the output very carefully before erasing the -s switch for the actual removal of the packages!
