See the announcement on /. today & read the link to the post from the guys that found it that is in the story, UCsomething IIRC, see below. A closer read may answer it. <https://ucrtoday.ucr.edu/39030> And please keep things like this on the list you read it from. A PM is unfair to the other readers of the list you read it on, so I'll cc the three lists it was cross posted to as it sounds pretty serious to me. And I just noted that the sysctl command you quoted above is incorrect, its sysctl -p, not sysctl.p. Maybe that helps?

Hi The latest stable seamonkey freezes every 10 min or so, using Kubuntu 14.04, that did not happen in Kubuntu 10.04. Does anybody have a similar experience? Uwe Brauer

Workaround for serious TCP exploit
by Felmon Davis 10 Aug '16

10 Aug '16

Greets! what must we who are using trinity do to avoid the tcp exploit? I found the following instructions from L. Weinstein's privacy mail list but they don't corrrespond to anything in my sysctl.conf. Felmon ----- quote ----- Workaround for serious TCP exploit previously discussed https://plus.google.com/+LaurenWeinstein/posts/gWSj2sYExoB Here is the recommended workaround for Linux/Android clients/servers for the serious TCP exploit discussed in: https://threatpost.com/serious-tcp-bug-in-linux-systems-allows-traffic-hija… This one will work for Ubuntu as is, and for various other Linux distributions with suitable modifications. The point is to bump the ACK limit way up. Note that some of the pages announcing this exploit appear to be contaminated with browser hijack "fake technical support" warning sites. Beware. Close your browser immediately if you hit one if you can, otherwise reboot and don't restore crashed pages. The workaround for the TCP exploit: Open /etc/sysctl.conf, append a command: /net.ipv4/tcp_challenge_ack_limit = 999999999 Use "sysctl -p" to update the configuration. _______________________________________________ privacy mailing list https://lists.vortex.com/mailman/listinfo/privacy

Problem on ubuntu 16.04 with systemd and tdm-trinity and a proposed solution
by update 09 Aug '16

09 Aug '16

On booting a new installed xenial with trinity tdm I get the error message: "A start job is running for Hold until boot process finishes up(time/no limit)" which prevents starting the console logins. Using sddm or lightdm works together with systemd. I have looked into the systemd configuration of them both and changed the file /lib/systemd/system/tdm.service according to the sddm configuration to [Unit] Description=Trinity Display Manager Documentation=man:tdm-trinity(1) Conflicts=getty(a)tty7.service After=getty(a)tty7.service # Ordering Conflicts=plymouth-quit-wait.service After=systemd-user-sessions.service plymouth-start.service plymouth-quit-wait.se OnFailure=plymouth-quit.service [Service] # temporary safety check until all DMs are converted to correct # display-manager.service symlink handling ExecStartPre=/bin/sh -c '[ "$(basename $(cat /etc/X11/default-display-manager 2> ExecStart=/opt/trinity/bin/tdm Restart=always RestartSec=1s With this file the plymouth/systemd handshake seams to work. Maybe this helps someone else. Stef

[probably OT] How to add a scancode?
by iadest＠o2.pl 07 Aug '16

07 Aug '16

Hello This is probably not related to TDE, but Linux in general (Debian 8?). I have a multimedia PS/2 keyboard "BTC 9001" (evtest reports it as "AT Translated Set 2 keyboard") and I try to use all its keys. Some are typical multimedia keys, while I program some other to launch applications in my TDE using "Keyboard actions" panel. Unfortunately not all keys are detected in OS by scancodes. Two keys generate only a EV_MSC event, while not giving scancode. Is it possible, by e.g. udev hwdb rule, to assign scancodes to these events? Here are results of evtest events test: Testing ... (interrupt to exit) Event: time 1470587826.798369, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1c Event: time 1470587826.798369, type 1 (EV_KEY), code 28 (KEY_ENTER), value 0 Event: time 1470587826.798369, -------------- EV_SYN ------------ Event: time 1470587829.689519, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1e Event: time 1470587829.689519, type 1 (EV_KEY), code 30 (KEY_A), value 1 Event: time 1470587829.689519, -------------- EV_SYN ------------ Event: time 1470587829.753248, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1e Event: time 1470587829.753248, type 1 (EV_KEY), code 30 (KEY_A), value 0 Event: time 1470587829.753248, -------------- EV_SYN ------------ Event: time 1470587836.420023, type 4 (EV_MSC), code 4 (MSC_SCAN), value e5 Event: time 1470587836.420023, type 1 (EV_KEY), code 217 (KEY_SEARCH), value 1 Event: time 1470587836.420023, -------------- EV_SYN ------------ Event: time 1470587836.504746, type 4 (EV_MSC), code 4 (MSC_SCAN), value e5 Event: time 1470587836.504746, type 1 (EV_KEY), code 217 (KEY_SEARCH), value 0 Event: time 1470587836.504746, -------------- EV_SYN ------------ Event: time 1470587839.705553, type 4 (EV_MSC), code 4 (MSC_SCAN), value a6 Event: time 1470587839.705553, -------------- EV_SYN ------------ Event: time 1470587839.782562, type 4 (EV_MSC), code 4 (MSC_SCAN), value a6 Event: time 1470587839.782562, -------------- EV_SYN ------------ Event: time 1470587840.546297, type 4 (EV_MSC), code 4 (MSC_SCAN), value a5 Event: time 1470587840.546297, -------------- EV_SYN ------------ Event: time 1470587840.648616, type 4 (EV_MSC), code 4 (MSC_SCAN), value a5 Event: time 1470587840.648616, -------------- EV_SYN ------------ Event: time 1470587842.578400, type 4 (EV_MSC), code 4 (MSC_SCAN), value 1d Event: time 1470587842.578400, type 1 (EV_KEY), code 29 (KEY_LEFTCTRL), value 1 Event: time 1470587842.578400, -------------- EV_SYN ------------ Event: time 1470587842.761042, type 4 (EV_MSC), code 4 (MSC_SCAN), value 2e Event: time 1470587842.761042, type 1 (EV_KEY), code 46 (KEY_C), value 1 Event: time 1470587842.761042, -------------- EV_SYN ------------ The keys pressed are: Return key released, A, then "Search" custom key which works, then "Manual" and "Panel" keys (these two don't work - no scancode), then ctrl-C to stop evtest.

Update problems I don't master
by Thierry de Coulon 07 Aug '16

07 Aug '16

So I took a look at my packages and saw that there were updates to TDE (from 14.0.0 to 14.0.3, openSUSE here). I first choose "update if newer" for all my packages (in Yast) and ended in a disaster: apparently minimal X with a terminal, message about wrong permissions for Xorg. Setting these permissions right let me start X... but only in KDE 4! I thought the problem was with openSUSE, so I restored and tried updating only Trinity. This time the message is: .servauth.1668 does not exist cannot open /var/log/xorg.1.log please consult X.org foundation support There are plenty of lines with (EE) too Same correction to Xorg now brings up Icevm. I'm out of my depth here. I restored again and will make a copy install to investigate the matter. I understand this may be openSUSE linked but any suggestion can help. Not urgent however, 14.0.0 is running very well... Thierry

MX-15 sound loss in VLC
by Joe 05 Aug '16

05 Aug '16

I've had some sound problems in MX-15 with VLC and Trinity. The issue is solved... sort of. This is a link to the discussion: http://forum.mepiscommunity.org/viewtopic.php?f=100&t=40197 The short version is: After I installed KDE Plasma Desktop, the problems cleared up. Recently, they started again. If I log out of TDE, log into Plasma Desktop, log out of Plasma, then back into TDE, I have sound again in VLC.

New problem Ubuntu 16.04 TDE 14.04
by Jonesy 04 Aug '16

04 Aug '16

I'm trying to get moneydance to run on on 64-bit Ubuntu 16.04 -- the last application necessary to permit my wife to move off Windows forever... (Moneydance is a financial bookkeeping Java program somewhat ala Quicken.) I've installed the new "amd64" moneydance as instructed by their website, and I get this when I try to run it: |$ Moneydance |[kcrash] TDECrash: Application 'output.logl-gtk-tqt-application' crashing... .. and I'm dumped back at the command line prompt. About half the time I do NOT get the "TDECrash" message. I am simply dumped back at the command line prompt after 5-6 seconds. I just know if I tell the moneydance support I have a "TDECrash", they'll ask me to bring it up under Gnome.... _All_ I have is Trinity. How to debug this "TDECrash"? Jonesy
