x2goserver on salix
by nanook＠eskimo.com 20 Mar '19

20 Mar '19

I've followed what scant documentation I can find about installing x2goserver and mate-desktop on Salix. The desktop works locally, even though it uses gdm rather than lightdm normally associated with mate-desktop. When I try to access remotely x2goclient hangs. I've attached a screenshot of what I see when it hangs.

Centos6 to Mint
by Robert Dinse 19 Mar '19

19 Mar '19

I've got a Mint server with the latest everything, that is it is completely up to date. I have a client trying to use x2go from work and is getting the complaint about SHA1, my system won't accept it, but only from x2go. If he connects with straight ssh it connects okay. Does x2go enforce a different set of encryption protocols than ssh it's tunneling through? -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

I run about a dozen virtual machines on it, an apache server, mail, shell servers. Might be up to around 50 people at a time. Some graphical, some just simple ssh sessions. Web server averages about 8 hits/second. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

"Connection to Local Desktop" without unlocking the physical display?

Hello list, is there a way to use "Connection to Local Desktop" of a machine without unlocking its physical display? (I.e. what is asked for in https://askubuntu.com/questions/288988/how-to-connect-to-existing-x-session… ) Best regards, Robert

Server hardware, memory
by Paul van der Vlis 18 Mar '19

18 Mar '19

Hello, I think about building a X2go server for about 30 sessions at the same time with XFCE, Firefox, Thunderbird, LibreOffice. Not sure about which hardware to use. I would say this: 4GB for the system 4GB for shared binaries like Firefox, Thunderbird, LibreOffice 1GB for a user what I would give 4GB on a fat client. 2GB for a power-user what I would give 8GB on a fat client. When I count on 5 powerusers and 25 normal users I would say 35GB + 8GB =43GB. Not sure about the shared binaries, is this "per processor"? I think about a server with 2 processors. I think one processor is enough, but it's not expensive to find a used one with 2 processors and much memory. I think about running it virtualized with Qemu/KVM/libvirt what also will take some memory. I think 48 GB is a correct RAM size. Please correct me when I am wrong! I guess it will be possible to run a server with 16GB with 30 sessions, but it will be "not nice". What is your experience?

x2gocheckport

I copied x2gocheckport from a ubuntu system upon which x2go is working properly and it is identical byte for byte with the one on manjaro throwing those errors. -_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_- Eskimo North Linux Friendly Internet Access, Shell Accounts, and Hosting.

Issue (typo?) with SPF record
by Chris Puttick 17 Mar '19

17 Mar '19

Hi I just subscribed to the list (hi!) and the confirmation email arrived in Google Mail's spam. While their spam filter has becoming over-sensitive in recent times, in this case it appears to be a typo in the SPF record: "v=spf1 include:das-netwzerkteam.de mx ?all" where das-netwzerken.de is an NXDOMAIN (should be das-netzwerken.de?) Regards Chris -- @putt1ck putt1ck.blogspot.com skype: putt1ck Opinions in this email are my own and may not reflect that of my clients, past employers, associates, friends, family, pets etc..

x2go Connecting from Mac to Linux
by Ute Roehrig 15 Mar '19

15 Mar '19

Hello, I've been using x2go for a long time to connect from a Mac to a Linux Desktop running Kubuntu 16.04 (KDE running locally). A few weeks back I ran into trouble with x2go crashing very often, and each time killing my VPN connection. To understand if the OSX version was the problem, I updated my Mac from 10.13. High Sierra to 10.14.3 Mojave, but the problem persists. Some observations: When connecting to the Linux Desktop without VPN (possible only when physically connected to the same network), the problem persists. When running only the VPN without x2go, the connection is stable. Non-graphical ssh sessions are stable. Connecting to a suspended session seems to make things worse (more frequent crashes). Using xfce or mate doesn't change anything. When running the x2go client (Version 4.1.2.1) in debug mode, at a certain point (but not upon startup) I get one of the following messages: x2go-DEBUG-../src/sshmasterconnection.cpp:2193> "ssh_channel_open_session failed": "Socket error: Connection reset by peer" x2go-DEBUG-../src/sshmasterconnection.cpp:2193> "ssh_channel_open_session failed": "Socket error: No such file or directory" x2go-DEBUG-../src/sshmasterconnection.cpp:2193> "ssh_channel_open_session failed": "Socket error: Can't assign requested address" x2go-DEBUG-../src/sshmasterconnection.cpp:2193> "ssh_channel_open_session failed": "Socket error: Operation timed out" Any help would be greatly appreciated! -Ute
