Question about the change in proxy/nx3.py
by Pavel 30 Apr '20

30 Apr '20

Hi, I am using my own small python application which is based on X2GoClient class from python-x2go. The application runs on windows, so it is necessary to start nxproxy.exe. The binary sits in C:\Users\user\win_apps\nxproxy\nxproxy.exe and in my app I set the environment variable NXPROXY_BINARY pointing to this path. This whole thing worked very well with python-x2go==0.5.0.6. Now I am on my way from Python2 to Python3, so I noticed, the newer version of python-x2go is also trying to be … [View More]

X2Go, MFA and Duo?
by James M. Pulver 28 Apr '20

28 Apr '20

Has anyone ever used X2Go Client (windows, linux, mac) with some sort of MFA that works in SSH? Duo and PortalGuard both support SSH MFA with either a "line client" or easier IMHO an appended password. I was wondering if Duo with the appended code to the password field might work? Also, is there any plans to add a second password field to the clients al la Cisco AnyConnect etc? Thanks, -- James Pulver CLASSE Computer Group Cornell University

I just updated to kde-20 on fedora 31, and once again trying kde over wayland. Previously x2go wouldn't work, but trying it now it seems to be working!

Is there a broker that does NOT require root to install?
by Dr Agile 26 Apr '20

26 Apr '20

I have a shared host in Namecheap. I have SSH access, but no root, so no APT-GET. I do have wsgi, with limited access to the httpd conf files, and do have access to .htaccess though. Is there a precompiled static binary, or a python / php script I can use with apache?

That’s the point. Gpg-cards. We too had those sun-machines for evaluation, but declined. When ones whole organization is using PKI, with 65,000 cards around, pkcs11 is essential. Would be nice to have a proper Citrix alternative.

One obviously missing, is a SmartCard, loaded with SSL keys & certificates, that should be reachable through P11 (or pkcs11) library...

Also, is there any plans to add a second password field to the clients al la Cisco AnyConnect etc? X2GoClient has out-of-the-box support for several 2FA solutions: <https://code.x2go.org/gitweb?p=x2goclient.git;a=blob;f=src/sshmasterconnect…> 53 "Verification code:", // GA (http://github.com/google/google-authenticator) 54 "One-time password (OATH) for", // OATH (http://www.nongnu.org/oath-toolkit/pam_oath.html) 55 "passcode:", // MOTP (http://motp.sourceforge.net) 56 "Enter PASSCODE:", // SecurID 57 "YubiKey for" // YubiKey (https://en.wikipedia.org/wiki/YubiKey) If Duo needs an appended code, it should work out of the box as well; if not, it will need to use either one of the prompts above to work out of the box, or one unique to Duo that we can add to a future client release. Frankly, I don't see a reason for the hype around Duo - what does it do that any of the established 2FA solutions can't do? When we looked at that after a customer had asked us about it, all it seemed to do was add a single point of failure, as it needed to "phone home" to a central Duo server (not under the customer's control) before being able to grant access. Block/sabotage that connection and you've essentially DoS'ed the system. Solutions based on Google Authenticator, or more generally, OATH, need no such external connection. I would assume the same goes for MOTP, YubiKey and SecureID. My personal favorite at the moment is Google Authenticator, which, despite what its name might suggest, does not "phone home" to Google. And you don't need to run the actual Google-Authenticator-App on your phone, either - any open source OTP app that supports TOTP OATH will do. Not sure what Cisco AnyConnect does or why we should add a second password field on the default login screen - that doesn't seem to make sense. All that would do is confuse users that don't use 2FA. And we don't know if a server uses 2FA or not until after we've provided a username and password to it, so there's no way of determining whether or not we should present a field for the 2FA code on the login screen. Hence, the popup for it. -Stefan -- BAUR-ITCS UG (haftungsbeschränkt) Geschäftsführer: Stefan Baur Eichenäckerweg 10, 89081 Ulm | Registergericht Ulm, HRB 724364 Fon/Fax 0731 40 34 66-36/-35 | USt-IdNr.: DE268653243 _______________________________________________ x2go-user mailing list x2go-user(a)lists.x2go.org https://lists.x2go.org/listinfo/x2go-user Dit bericht kan informatie bevatten die niet voor u is bestemd.

x2go kdrive & windows client
by Михайло Падалка 24 Apr '20

24 Apr '20

Tried to understand why x2gokdrive does not work from Windows client, and found that there is no x2gokdrive binary installed with latest client. But looking into git history I see there are some commits related to windows support. Is it simply not packaged, or not ready? -- З повагою, Михайло

The mapping in this case is without effect because it maps desktop-environments to commands but the parameters given to x2goruncommand don't show KDE. Instead x2goruncommand receives startkde directly (from where ever). Custom desktop with /startplasma-x11/ starts the session (because $cmd is set to /startplasma-x11) /and passes till the end.

Getting delays when adjusting windows/web browsing
by Brant Pastore 17 Apr '20

17 Apr '20

My host is kubuntu 18.04, I have installed x2go server version 4.1.0.3-0~170. I'm using windows 10 to connect with x2go client 4.1.2.2. I get delays in scrolling on firefox, or chrome. I also get very noticeable stutters when dragging a window to move it, or maximizing. (Heres a GIF of what I'm talking about https://gph.is/g/ZORllLz ) I have good connection speeds - https://imgur.com/gKFzKkn (both machines are on LAN connected via the same switch) I've tried quite a few different connection … [View More]
