| 02:46 | * work_alkisg waves | |
| 02:46 | work_alkisg is now known as alkisg | |
| 02:46 | <alkisg> vagrantc: about port 6007, isn't that "-nolisten tcp"?
| |
| 02:49 | <vagrantc> alkisg: that's what i was wondering
| |
| 02:50 | alkisg: -nolisten tcp is definitely enabled
| |
| 02:50 | <alkisg> I don't have it here in my thin client
| |
| 02:50 | So, it does listen on tcp...
| |
| 02:50 | I mean, we need to pass "-nolisten tcp" when we're not using LDM_DIRECTX=True
| |
| 02:51 | <vagrantc> /etc/X11/xinit/xserverrc:exec /usr/bin/X -nolisten tcp "$@"
| |
| 02:51 | thought we use xinit ... maybe it doesn't call xserverrc i guess
| |
| 02:52 | <alkisg> xinit /usr/share/ltsp/xinitrc /usr/sbin/ldm -- :7 vt7 -auth /var/run/ldm-xauth-sWqADSace/Xauthority -depth 16 -br
| |
| 02:52 | That's my xorg command line here
| |
| 02:52 | And, X :7 vt7 -auth /var/run/ldm-xauth-sWqADSace/Xauthority -depth 16 -br
| |
| 02:52 | <vagrantc> sure
| |
| 02:53 | i guess we can't handle that in the xinitrc wrapper... as it's not going to pass the arguments to X
| |
| 02:54 | <alkisg> In my local Ubuntu installation, my xorg command line is: /usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
| |
| 02:54 | Which means that xserverrc isn't used there either
| |
| 02:54 | <vagrantc> not following you there...
| |
| 02:55 | gdi2k__ has joined IRC (gdi2k__!~gdi2k@49.151.60.165) | |
| 02:55 | * vagrantc has no idea where xserverrc is used | |
| 02:55 | <alkisg> I mean that I think that /etc/X11/xinit/xserverrc is never used, it's not our fault that it's not executed
| |
| 02:55 | So we just need to conditionally pass -nolisten tcp from our own xinitrc
| |
| 02:55 | <vagrantc> alkisg: but you just told me something is using -nolisten tcp on your local install
| |
| 02:55 | <alkisg> Right, so probably lightdm does that
| |
| 02:56 | ./screen.d/ldm:exec xinit $xinitrc /usr/sbin/ldm -- ${DISPLAY} vt${TTY} -auth ${XAUTHORITY} ${X_ARGS} -br >/dev/null 2>&1
| |
| 02:57 | That "exec" line needs to be inside an "if"
| |
| 02:57 | If LDM_DIRECTX is True, don't add -nolisten tcp
| |
| 02:57 | Add -nolisten tcp all the other times, either in kiosk, or in rdesktop, or in fat clients etc
| |
| 02:57 | <vagrantc> or just add it to X_ARGS ?
| |
| 02:58 | <alkisg> From screen-x-common, sounds good
| |
| 02:58 | <vagrantc> remote or local apps have any issues
| |
| 02:59 | <alkisg> local apps => why?
| |
| 02:59 | remote apps => should use the same method as LDM_DIRECTX, so the ssh tunnel when it's false
| |
| 03:00 | telex has left IRC (telex!~telex@freeshell.de, Remote host closed the connection) | |
| 03:02 | telex has joined IRC (telex!~telex@freeshell.de) | |
| 03:03 | <vagrantc> just the cases i thought of that might have issues
| |
| 03:03 | but seems fine
| |
| 03:06 | hah. get_xfs_settings
| |
| 03:06 | alkisg: LDM with DIRECT_X=true is the only place where that's needed, right?
| |
| 03:07 | <alkisg> I think so, yeah - but I'm not sure that currently remoteapps are using the ssh tunnel
| |
| 03:08 | <vagrantc> we could set a default variable and then unset it in that case
| |
| 03:08 | remoteapps use the ssh tunnel
| |
| 03:08 | <alkisg> *the only place that it's NOT needed (the -nolisten tcp)
| |
| 03:09 | <vagrantc> so i'm thinking of setting a new variable, that defaults to "-nolisten tcp", and unsettng it in the ldm screen script when LDM_DIRECTX=true
| |
| 03:10 | because you could have a setup with LDM_DIRECTX=true with SCREEN_07=ldm and SCREEN_08=rdesktop
| |
| 03:10 | <alkisg> Why use a variable instead of X_ARGS directly?
| |
| 03:11 | Hmm...
| |
| 03:12 | <vagrantc> because it's easier to unset a variable that doesn't have other variables in it
| |
| 03:12 | other values in it
| |
| 03:12 | <alkisg> (sorry I wrote before reading, ok...)
| |
| 03:12 | <vagrantc> i.e. -depth $X_COLOR_DEPTH and -config $X_CONF
| |
| 03:12 | thanks for bringing it up ... it left me unsettled
| |
| 03:13 | or we hard-code it in all the others, and conditionally enable it in ldm screen script
| |
| 03:13 | that would be simple, too.
| |
| 03:14 | i think i'm inclined towards that, really.
| |
| 03:15 | except we have to hard-code it in multiple places...
| |
| 03:15 | <alkisg> Yes the downside is a commit with multiple files changed
| |
| 03:16 | We *can* strip "-nolisten tcp" from X_ARGS in ldm when needed, it's just a bit more ugly
| |
| 03:16 | It's a smaller .diff though
| |
| 03:19 | <vagrantc> i think xdmcp needs to leave it out
| |
| 03:20 | we should probably drop support for the old compatibility without the xinit stuff
| |
| 03:21 | er, /usr/share/ltsp/xinitrc
| |
| 03:21 | * alkisg doesn't remember what "startx" is for... | |
| 03:21 | <vagrantc> alkisg: i renamed startx to xdmcp
| |
| 03:21 | <alkisg> Whoops sorry didn't see that it's a symlink
| |
| 03:21 | <vagrantc> yeah
| |
| 03:22 | <alkisg> OK that's a much smaller diff then
| |
| 03:22 | We only need to put that in xterm, xfreerdp, kiosk, and ldm?
| |
| 03:23 | <vagrantc> that's my guess
| |
| 03:23 | <alkisg> ...hardcoding sounds fine... :)
| |
| 03:24 | Dropping the "if [ -x /usr/share/ltsp/xinitrc ]; then" sounds good too
| |
| 03:25 | <vagrantc> maybe we should do that first.
| |
| 03:39 | * vagrantc pushes in ltsp | |
| 03:54 | * vagrantc pushes to ldm | |
| 04:08 | <alkisg> Nice!
| |
| 04:10 | vagrantc: don't we also need an "if LDM_DIRECTX=True" ?
| |
| 04:11 | if ! boolean_is_true "$LTSP_FATCLIENT" ; then
| |
| 04:11 | ==>
| |
| 04:11 | if ! boolean_is_true "$LDM_DIRECTX"; then
| |
| 04:13 | With a sidenote that, if LTSP_FATCLIENT=True, and LDM_DIRECTX=True, that means that remoteapps won't use the ssh tunnel
| |

| 06:48 | <det_> ltsp` , a few days ago you sad: "If you changed your LTSP server IP on Ubuntu, your clients will be unable to login. To fix this, you need to run: sudo ltsp-update-sshkeys && sudo ltsp-update-image" I don't understand what should i do. I've executed update sshkeys after i moved i386.img file with linux mint to ubuntu's lts server. Then i've made image update, but (hah) it just recreated old ltsp system image.
| |
| 06:51 | I will repeat: 2 servers, 1 main ltsp with ubuntu, 2 - testing server with mint on ltsp. I want to use mint image for users (in chroot), but i can't reinstall main system from ubuntu to mint.
| |
| 06:51 | So i've copied mint image to ubuntu's ltsp, but users can't login.
| |
| 06:54 | I did even more. I've made a tar archive of whole mint's chroot system, moved it to main ltsp server, and when i try #ltsp-update-sshkeys -b /opt/ltsp/mint && ltsp-update-image -b /opt/ltsp/mint
| |
| 06:54 | It says : No LTSP chroots found, please run ltsp-build-client

| |
| 14:28 | <alkisg> Install the debian 486 kernel in the chroot
| |
| 14:29 | <ajbotani> How to proceed, can you help me with a step by step?
| |
| 14:30 | <alkisg> Sorry, no time to help step by step on how to install a debian package
| |
| 14:30 | https://packages.debian.org/wheezy/linux-image-3.2.0-4-486
| |
| 14:32 | <ajbotani> seria com o comando sudo ltsp-build-client --arch i486
| |
| 14:32 | would be with the command sudo ltsp-build-client --arch i486
| |
| 14:33 | <alkisg> No, with chroot and wget and apt-get install
| |
| 14:34 | <ajbotani> Got it, thanks!

| 17:03 | <hurin> hello
| |
| 17:04 | is there a soft client to connect a virtual desktop?
| |
| 17:04 | <alkisg> You mean e.g. a virtual thin client that runs inside virtualbox or kvm?
| |
| 17:04 | <hurin> like, if my users have Windows PCs but they need access to their Linux Desktop, can they connect using a program?
| |
| 17:05 | <alkisg> x2go
| |
| 17:06 | <hurin> asesome, thank you, I will dig into that
| |
| 17:06 | <championofcyrodi> the new NoMachine 4.0 client will work well
| |
| 17:06 | has collaboration features and stuff too
| |
| 17:06 | you'd just need to install it on the linux desktops as well
| |
| 17:06 | <hurin> nomachine connects flawlessly, but only one user at a time
| |
| 17:07 | <alkisg> championofcyrodi: what does that need on the server part?
| |
| 17:07 | <hurin> nomachine 4 works as server and client
| |
| 17:07 | the same piece is installed on both ends
| |
| 17:07 | but only 1 user at a time
| |
| 17:07 | in my scenario, several users of a Linux desktop need remote access
| |
| 17:07 | <championofcyrodi> another instance of nomachine. when they went to version 4, the got rid of the open NX protocol and started their own NX protocol using port 4000
| |
| 17:08 | instead of SSH
| |
| 17:08 | <hurin> just as Remote DEsktop Protocol does for Windows to WIndows
| |
| 17:08 | <championofcyrodi> i think they actually just call the protocol "NX"
| |
| 17:08 | <alkisg> Ah like teamviewer, yes that doesn't help multiple users that want remote access to the same server
| |
| 17:08 | x2go is the best I've found for that so far
| |
| 17:08 | <championofcyrodi> i remember seeing multiple 'sessions' started and being able to connect to those sessions with nomachine.
| |
| 17:09 | <alkisg> VNC can be used too but with no benefit over x2go, it's worse
| |
| 17:10 | <hurin> @championofcyrodi nomachine used to work for me at one time, now I can't use it to connect a nomachine 3 or 4 client
| |
| 17:11 | <championofcyrodi> right... they dont support NX over SSH anymore.
| |
| 17:11 | https://www.nomachine.com/AR10K00728
| |
| 17:11 | unless of course, you buy their enterprise version
| |
| 17:12 | like 'Workstation, Terminal Serer, Cloud Server, etc...'
| |
| 17:13 | <hurin> so version 4 works very well but only 1 user at a time
| |
| 17:13 | will check if x2go does the trick
| |
| 17:13 | <championofcyrodi> you can still find version 3.5 here http://www2.vrdc.cornell.edu/news/ecco/step-4-using-ecco/nx-client-3-5/
| |
| 17:13 | <hurin> I can't believe there isn't a good solution for this on Linux Desktops x(
| |
| 17:13 | have you people ever felt the need for such a software?
| |
| 17:14 | * alkisg is using x2go regularly, it's fine | |
| 17:15 | alkisg has left IRC (alkisg!~alkisg@ubuntu/member/alkisg, Quit: Leaving.) | |
| 17:15 | <championofcyrodi> there is a solution x2go, nomachine, rdesktop, and plain jane X11 forwarding.
| |
| 17:15 | but honestly, most of us probably just use SSH/console/vi/vim/nano
| |
| 17:15 | tmux
| |
| 17:16 | even IRC has console based chat clients
| |
| 17:16 | <hurin> mmm, I wouldn't call them solutions. I have found all of those options complex, incompatible, limited and hard to configure. Would you agree?
| |
| 17:16 | <championofcyrodi> yes. I would agree that you have found all those options to be complex, incompatible, etc..
| |
| 17:16 | <hurin> hehehe
| |
| 17:17 | but they are, objectively
| |
| 17:17 | <championofcyrodi> what are your windows users doing on linux?
| |
| 17:17 | <hurin> well
| |
| 17:17 | <championofcyrodi> when i had Windows workstation in the past, i got all done with Xming & PuTTY
| |
| 17:17 | <hurin> those are linux jump-boxes
| |
| 17:17 | <championofcyrodi> jump-boxes?
| |
| 17:18 | <hurin> they have a differnt network connection that allows access to a cloud with lab servers
| |
| 17:18 | not much I can do to change that part....
| |
| 17:19 | <championofcyrodi> so a 'jump-box' is a workstation with a network connection to a cloud?
| |
| 17:19 | <hurin> but I can implement linux machines, IF I can solve the remote desktop dilema
| |
| 17:19 | yes
| |
| 17:19 | <championofcyrodi> you can run linux applications with X11 forwarding over SSH.
| |
| 17:19 | on the windows workstation just install xming
| |
| 17:19 | and download putty.exe
| |
| 17:20 | then when you run putty, enable x11 forwarding. then connect with SSH like normal.
| |
| 17:20 | then when you run gui applications like 'xclock' it will show up on windows
| |
| 17:20 | <hurin> I agree. xming does the trick up to some point. One of my friends set it up and he was able to grab the entire desktop
| |
| 17:20 | <championofcyrodi> yes you can also try to run the desktop session
| |
| 17:20 | but it does not always integrate well
| |
| 17:20 | which is why usually you just run the applications
| |
| 17:21 | like $ gedit &
| |
| 17:21 | <hurin> thing is, users have to deal with Putty, and they require it to be a dummy proof solution
| |
| 17:21 | <championofcyrodi> putty allows you to save configurations for connection... not much more dummy proof you can get besides clicking 'connect'
| |
| 17:22 | if they can't do that... they may need to be taking a pre-requisite course before using your workstations.
| |
| 17:22 | #training
| |
| 17:22 | <hurin> I have played with the idea of building a qt based project to provide a turnkey client solution (qt client + ssh + xming or something)
| |
| 17:22 | <championofcyrodi> seems like overkill
| |
| 17:23 | i'm sure putty takes arguments. you could make a BATCH file that runs it all
| |
| 17:23 | (since it's windows)
| |
| 17:23 | <hurin> hehe yup
| |
| 17:23 | humor me for a second on this thought
| |
| 17:25 | windows has a simple click to open technology called RDP. Users only put their user/password and are able to obtain their entire desktop experience as if the were sitting in front of their PC. One single application hidding any possible complexity behind it (protocols, security, media, clipboard, copy/paste, so on)
| |
| 17:25 | why isn't there a similar "solution" for linux environments??
| |
| 17:26 | oh! and there is the multi user capability as well.
| |
| 17:26 | <Hyperbyte> hurin, you mean something like X2Go?
| |
| 17:27 | <championofcyrodi> hurin: i understand your frustration. x2go is what you need to use. but no, it's not going to be as easy as windows native remote desktop.
| |
| 17:27 | to configure
| |
| 17:28 | especially since you will be using windows as a client and linux as a server
| |
| 17:28 | <hurin> yeah I guess x2go can do this http://askubuntu.com/questions/247115/remote-desktop-for-multiple-users
| |
| 17:28 | <championofcyrodi> again, i use free-nx and nomachine 3.5 to do windows->linux
| |
| 17:28 | but there are a lot of options
| |
| 17:28 | x2go seems to be the latest and greatest though
| |
| 17:28 | <hurin> really!!!?? you still use nomachine 3.5??
| |
| 17:28 | <championofcyrodi> so you should use that
| |
| 17:29 | <hurin> have you tried kde desktops??
| |
| 17:29 | <championofcyrodi> for windows -> linux
| |
| 17:29 | yes
| |
| 17:29 | i have tried kde
| |
| 17:29 | <hurin> dude, I would love to know how
| |
| 17:29 | <championofcyrodi> i don't use kde
| |
| 17:29 | <Hyperbyte> hurin, yes, X2Go can do that.
| |
| 17:30 | <championofcyrodi> i use xfce4 for nomachine 3.5
| |
| 17:30 | using CUSTOM startup script /usr/bin/startxfce4
| |
| 17:30 | which gives me the entire XFCE desktop. being a lightweight desktop i find it works well for remote sessions.
| |
| 17:30 | but on the actual workstation i use unity
| |
| 17:31 | which i guess is using LDM now
| |
| 17:31 | actually i'm sure it is... since i have custom configurations for greeting screen
| |
| 17:31 | <hurin> I have tried the trusty repositories from here https://launchpad.net/~freenx-team/+archive/ubuntu/trusty
| |
| 17:32 | and windows client 3.5, I see the authentication succeed, then a black screen, then it drops....
| |
| 17:32 | <championofcyrodi> it's because your trying to connect with gnome which has a bug supporting 2D desktops..
| |
| 17:32 | because the NX client fails the 3D accel check...
| |
| 17:32 | one sec.
| |
| 17:32 | and you'll see an error about 'the fail whale is dead!'
| |
| 17:33 | which is why i love free software.
| |
| 17:33 | (sarcasm)
| |
| 17:34 | so to get windows nomachine to freenx w/o blank screen...
| |
| 17:34 | on the linux box: #First install Xubuntu
| |
| 17:34 | apt-get install -y xubuntu-desktop
| |
| 17:35 | apt-add-repository ppa:freenx-team -y
| |
| 17:35 | apt-get update
| |
| 17:35 | apt-get install -y freenx-server
| |
| 17:35 | then for your desktop session when connecting from windows with nomachine... use the command 'startxfce4'
| |
| 17:36 | It's where you normally see "GNOME", "KDE", "XFCE", "CUSTOM" you'll want to choose custom.
| |
| 17:36 | <hurin> got it. I will try that tonight
| |
| 17:36 | so kde is not an option
| |
| 17:37 | at least with nomachine
| |
| 17:38 | Hyperbite, do you know if x2go supports kde_?
| |
| 17:39 | thank you very much championofcyrodi
| |
| 17:40 | <championofcyrodi> p
| |
| 17:40 | np
| |
| 17:41 | <hurin> wooow
| |
| 17:41 | x2go supports kde! http://wiki.x2go.org/lib/exe/fetch.php/doc:x2go1.png
| |

| |
| 18:51 | "< alkisg> vagrantc: don't we also need an "if LDM_DIRECTX=True" ?"
| |
| 18:52 | alkisg: i put code in the ldm screen script for that, where were you thinking?
| |
| 18:52 | +if ! boolean_is_true "$LTSP_FATCLIENT" ; then
| |
| 18:52 | + X_ARGS="-nolisten tcp $X_ARGS"
| |
| 18:53 | and "< alkisg> if ! boolean_is_true "$LTSP_FATCLIENT" ; then"
| |
| 18:53 | ah.
| |
| 18:53 | i did it wrong.
| |
| 18:53 | alkisg: thanks again
| |
| 18:54 | i suppose -nolisten tcp makes sense for fatclients as well
| |
| 18:55 | * vagrantc tests | |
| 19:02 | freedomrun has left IRC (freedomrun!~quassel@unaffiliated/freedomrun, Read error: Connection reset by peer) | |
| 19:05 | <alkisg> vagrantc: right, I meant that we shouldn't test for thin/fat at all, just for ldm_directx
| |
| 19:06 | -nolisten tcp for fats should be the default, right, no need to special-case it
| |
| 19:07 | <vagrantc> i typoed the first one
| |
| 19:07 | well, mentally typoed
| |
| 19:08 | i think LTSP_FATCLIENT will actually need special casing as well, though
| |
| 19:08 | since the default for ldm is to not have "-nolisten tcp"
| |
| 19:08 | <alkisg> The default for ldm should be -nolisten tcp,
| |
| 19:09 | and it should be removed when LDM_DIRECTX=True
| |
| 19:09 | What else is needed there?
| |
| 19:09 | No mention of thin/fats at all, no special casing
| |
| 19:10 | <vagrantc> it's easier to add it than remove it
| |
| 19:10 | <alkisg> Specifically, you only need to change one word in your commit
| |
| 19:10 | boolean_is_true $LTSP_FATCLIENT ==> boolean_is_true $LDM_DIRECTX
| |
| 19:10 | <vagrantc> yes, but that will leave it for LTSP_FATCLIENT, which it shouldn't.
| |
| 19:11 | so yes, i committed the wrong code.
| |
| 19:11 | <alkisg> Meh bzr says service unavailable... can't see the diff online... pulling...
| |
| 19:12 | (10:10:57 μμ) vagrantc: yes, but that will leave it for LTSP_FATCLIENT, which it shouldn't. ==> I don't think that's true
| |
| 19:12 | Let's sum up with a table:
| |
| 19:13 | FAT? no. DIRECTX? no ==> -nolisten
| |
| 19:13 | FAT? yes. DIRECTX? no ==> -nolisten
| |
| 19:13 | FAT? no. DIRECTX? yes ==> listen
| |
| 19:13 | FAT? yes. DIRECTX? yes ==> listen
| |
| 19:13 | So "listen" is the same as "directx"
| |
| 19:13 | It doesn't depend on thin/fat
| |
| 19:15 | telex has left IRC (telex!~telex@freeshell.de, Remote host closed the connection) | |
| 19:15 | <vagrantc> ah, FAT with DIRECTX would be fore remoteapps without ssh...
| |
| 19:15 | <alkisg> Yup
| |
| 19:15 | For faster remoteapps
| |
| 19:16 | So when I'm saying "LDM_DIRECTX=True", I'm declaring that I prefer speed over security for both my thin and fat clients (remoteapps)
| |
| 19:16 | telex has joined IRC (telex!~telex@freeshell.de) | |
| 19:18 | <vagrantc> ok, so it really is just a typo, not needing to get into more complicated stuff.
| |
| 19:19 | <alkisg> Only 1 word needs to be changed, yup
| |
| 19:19 | <vagrantc> for a strict fat client, specifying DIRECT_X won't make any difference, only when you get into localapps
| |
| 19:19 | er, remoteapps
| |
| 19:20 | <alkisg> It will make it more secure
| |
| 19:20 | No ports open
| |
| 19:20 | <vagrantc> sure
| |
| 19:20 | <alkisg> Nothing else, yeah
| |
| 19:20 | <vagrantc> wish i hadn't botched that commit, thanks for catching it!
| |
| 19:21 | and i used the correct variable in the commit log, just not the code, which makes it extra confusing
| |
| 19:21 | <alkisg> I'm just worried if all this will work as it is, or if we need to fix a few things in remote/localapps
| |
| 19:21 | It will need some testing...
| |
| 19:21 | vagrantc: I think you can lower your standards and uncommit :D
| |
| 19:21 | Noone will notice!
| |
| 19:21 | <vagrantc> and i botched my commit message for the fix, thankfully i'm not able to push!
| |
| 19:22 | alkisg: i've tried localapps on a thin client, and remoteapps with a fat client ...
| |
| 19:22 | haven't tried kiosk or xterm or xfreerdp, though
| |
| 19:22 | <alkisg> With both directx=true/false?
| |
| 19:23 | <vagrantc> i think so...
| |
| 19:23 | <alkisg> Cool :)
| |
| 19:23 | <vagrantc> because localapps runs on the local hardware, it doesn't connect via tcp
| |
| 19:23 | * vagrantc will test a few more times to be sure | |
| 19:24 | <alkisg> I haven't looked at the code recently, but I was under the impression that remoteapps weren't using the ssh tunnel even with the default LDM_DIRECTX=False
| |
| 19:24 | So I was expecting they'd work, but not as "expected"
| |
| 19:24 | * alkisg checks... | |
| 19:30 | <alkisg> Hmm no I can't find anything wrong, I don't know what I was thinking

| |

| |
| 19:50 | it's my only real-world ltsp useage at the moment
| |
| 19:50 | so the kiosk script should've give me any surprises...
| |
| 19:50 | i.e. i've been testing it lately
| |
| 19:51 | <alkisg> Surfing with a pi... ouch?
| |
| 19:51 | Isn't that too slow?
| |
| 19:51 | Ah you have javascript disabled etc... might be light enough that way
| |
| 19:51 | <vagrantc> i just use it to play music off of libre.fm
| |

| |
| 19:53 | * alkisg wants to upload something there.. sometime... | |
| 19:54 | <vagrantc> oooh!
| |
| 19:54 | ok, i've tested everything but xfreerdp
| |
| 19:57 | apt get install xrdp ...
| |
| 19:59 | hrm. well, xfreerdp doesn't seem to work with the defaults...
| |
| 20:02 | but it works when specifying RDP_SERVER=server and RDP_OPTS=-f
| |
| 20:03 | so the -nolisten tcp seems to work.
| |
| 20:03 | <alkisg> "xfreerdp server -f" ?
| |
| 20:03 | I don't think we default to "server"...
| |
| 20:04 | <vagrantc> it's got some defaults if no arguments are passed that don't seem to kick in
| |
| 20:07 | if [ $# -eq 0 ]; then RDP_OPTIONS=${RDP_OPTIONS:--f -u ''} RDP_SERVER=${RDP_SERVER:-server}
| |
| 20:11 | but it doesn't seem to work
| |
| 20:12 | <alkisg> vagrantc: try: RDP_OPTIONS=${RDP_OPTIONS:-"-f -u ''"}
| |
| 20:12 | If it works commit it, it seems like a bug to me
| |
| 20:13 | <vagrantc> alkisg: $# is returning 1 when $@ is apparently empty
| |
| 20:15 | probably whitespace or something
| |
| 20:15 | huh.
| |
| 20:15 | not that...
| |
| 20:16 | <alkisg> vagrantc: can you hexdump /proc/pidofxfreerdp/cmdine ?
| |
| 20:16 | <vagrantc> it's in the screen script, not in freerdp
| |
| 20:17 | <alkisg> "$script_path" "$args"
| |
| 20:17 | <vagrantc> maybe it's being passed a null argument
| |
| 20:18 | <alkisg> We're not allowing for empty $args there...
| |
| 20:18 | <vagrantc> test -z "$@" ... wouldn't catch ' ' as an arg...
| |
| 20:18 | <alkisg> "$*"
| |
| 20:20 | But it still needs to be fixed properly for empty args in the future...

| 22:00 | <vagrantc> stgraber: so, i noticed that the rdesktop plugin, unsurprisingly hard-codes rdesktop, though dropping in xfreerdp instead works fine...
