Interesting post, kontro! So we have several alternatives. If the
project goes down the drain (as it seems to), I think as a last effort
we should document the alternatives which current Adito/ALS users have.
On my previous work at the university of Copenhagen we were using SSL-
Explorer. I guess we had some 20 - 40 users logging in on a daily basis, using
different features in SSL-explorer. The use base was growing until 3sp pulled
the plug and we stopped promoting SSL-explorer.

I''ll state where SSL-explorer made a difference for us (most point has been
mentioned by other posts):

* The ability to work on locked down machines using the java client
* The ability to establish contact behind restrictive firewalls
* Ease of use (for end-users - mostly doctors and professors)

The user just launched the application from the web interface:
* Windows-remote desktop
* VNC-remote desktop
* web-proxy for accessing on-line libraries (IP based access)
* drive mapping for windows users.
* Ad-hoc solutions like when a user was on a network not allowing imaps we
could instruct over the phone how to configure a tunnel.


I have now moved to another department at the University. Here we use a Cisco-
vnp tingie (not sure - I have never used it, as ssh is sufficient for my
personal use) but I do think it looks troublesome to configure. We only
promote vpn to windows users who really really needs access to network drives
on the road.

The MUA is setup to use login over smtps/imaps so they work most places
(webmail used as fallback on restrictive networks)


If we look into the future:

The Microsoft guys told me that the new MS servers supports some kind of drive
mapping over SSL which solves the drive mapping issue for Windows users. They
also mentioned that new versions of outlook/exchange has some means of road-
warrior connectivity. So I guess when they get that monster airborne it will
solve most of the windows users problems.

Proxy access to other websites is currently provided by
http://sourceforge.net/projects/poxy/ on our web server.

For Linux users to access network drives I've successfully tested drive
mapping over ssh (sshfs) on Linux. But in many cases Dolphin, Nautilus or just
plain shell are sufficient. Many of our Linux users is powerusers anyway and
is not scared from using the shell

I'm unsure about MAC users.

On the remote desktop side we have not decided yet. NX machine look promising,
as it runs over ssh. But it has some issues with key mapping is f*****-up on
non us keyboards.

Luckily over time more and more services is moved to being web based, which
solves many of the above problems.

Still sometimes we have users ending up behind firewalls which do not allow
ssh, imaps or smtps. Here some kind of tunneling would be nice. Something like
http://ace-host.stuart.id.au/russell/files/http-proxy-tunnel/
might be able to solve the problem. But it seems not easy to configure on the
client machine.

Sorry this became a little long - I guess i just used this to summarized my
own thoughts on the subject.

Interesting project, have not seen that one.

If SSH access is available then I think Nautilus + gvfs-fuse works great.

I've used NX successfully over the last few years. It does indeed have
some keymap/language setting issues. Perhaps most annoyingly running a
local Gnome session and _then_ connecting via NX causes problems as
Gnome acts weird if more than one session is running for a user.

Looks a little "hackish" :).

Well, my initial post was even longer ;).

It seem that the project is abandoned tough - but hey if it works: dont fix
it. Anyway I think there is many alternatives for simple proxy solutions out
there. Might even be possible to combine it with SUMO Access Manager.

sshfs is fuse based as well I think. On my daughters little netbook I made a
simple solution by placing a sshfs connect script in the folder which is the
mountpoint. So when she enters the folder and the ssh file system is not
mounted, well the script is right there to be launched ;-)

But in many cases a Linux desktop user dont need mounting the filesystem at
all. At least KDE Dolphin can handle files directly over ssh by typing
fish://***@server in the path (I think Nautilus can do equal by typing
ssh:... in the path line).

Yep, Nautilus can access directories via SSH using
ssh://***@server:/path syntax. Alternatively you can create a shortcut
using "Connect to share + Add bookmark". The newer Gnome VFS versions
support fuse, meaning that all mounted remote drives are available under
$HOME/.gvfs/sftp on servername/ or similar.

This mail came from an old Adito/ALS user, Silvan M. Gebhardt, but was
rejected by SF.net. So here it comes:

If I may also contribute

I have just found the solution to replace the remaining functionality of
adito for me: The Kind-of-single-signon for the user.

I have just found http://sumoam.sourceforge.net/


I might be able to plug some of my existing apps onto that - then
everything works on a login. perhabs we can add some more functionality
like SMS token



personally, I'm starting to think about bilding some kind of appliance
on top of apache, consisting of openVPN, Apache Proxy, and this thingie
here, and some more stuff ;)



I run OpenVPN and an Apache ReverseProxy simultaneous on one Port btw.
The Portsharing Feature is one thing that we should point out. I have
used sslexplorer once when I only had port 80+443 available and I was
not able to have more than one IP Address. Portsharing of OpenVPN is
Really, Really incredible ;)
I'm thinking about suggesting the openvpn people the following


currently the openvpn daemon proxies (layer4) to the HTTPS server
running e.g on localhost. so it looks at the traffic if it looks like
openvpn or HTTPS. do you folks think if there is a way to also detect
SSH? So three services could share that port?
