I have a website that uses websocket-sharp for client-server communication and has a certificate issued by Let's Encrypt. Other browsers work, but Google Chrome (on Linux) gives the error ERR_SSL_VERSION_INTERFERENCE in the console. Disabling TLS 1.3 lets users circumvent this error. I am using the latest stable version.
This answer suggests the problem is when Chrome detects "buggy middleware" but I don't know what exactly Chrome is looking for.
This turned out to be a problem with Mono. Mono uses BoringSSL in newer versions but it isn't turned on by default in older versions. On newer Linux distributions you can do export MONO_TLS_PROVIDER=btls but that didn't work for me because the gcc compiler on CentOS 6 (version 4.4) is too old and doesn't support align which is necessary to compile BoringSSL.
First I installed gcc 4.8 with instructions from here: https://gist.github.com/stephenturner/e3bc5cfacc2dc67eca8b
wget -O /etc/yum.repos.d/slc6-devtoolset.repo http://linuxsoft.cern.ch/cern/devtoolset/slc6-devtoolset.repo
sudo yum install devtoolset-2
scl enable devtoolset-2 bash
Then I downloaded the latest release package of mono from their website (currently 5.12.0.226): http://www.mono-project.com/docs/compiling-mono/linux/
wget https://download.mono-project.com/sources/mono/mono-5.12.0.226.tar.bz2
tar xvf mono-5.12.0.226.tar.bz2
cd mono-5.12.0.226
./configure --prefix=/usr/local
make
make install
Just in case, I did export MONO_TLS_PROVIDER=btls too, although I don't think it's necessary, but regardless if you look at the output at the end of ./configure it should tell you if BTLS is enabled.
This also fixed the same problem with recent Firefox update 60.0.0.2.

The release notes for RedHawk 2.0 say that the GPP device previously written in Python has been replaced with one written in "Written in C++, so it is more responsive". But I find it still running in Python (according to ps command python is running GPP.py, and the $SDRROOT/dev/devices/GPP/GPP.spd.xml which also has softpkg version="1.10.0". Was my installation defective and I still have parts of the 1.10 runtime system? My IDE says 2.0.
It sounds like REDHAWK 2.0 was not properly installed on your system, the IDE and the framework/assets are separate and it is possible to get into a situation with conflicting versions depending on the installation steps taken.
Determining what version of REDHAWK you have installed can be determined in a handful of ways. If you installed via yum or rpm you can check the versions of the rpms installed with:
rpm -qa | grep -i redhawk
The redhawk package, and redhawk-ide package should both be at 2.0. Note that the REDHAWK assets are versioned independently.
If you installed via source, you can use the package config files to obtain version information. The framework keeps it's pc files in $OSSIEHOME/lib64/pkgconfig:
cat $OSSIEHOME/lib64/pkgconfig/ossie.pc
Will print out version information for the core framework installed. Depending on what is installed, there are pc files for the framework, bulkio, frontend, and burstio.
I am sorry. The GPP-2.0.0-3.el6.x86_64 DOES contain an ELF executable for GPP device. But the rpm does not install unless I manually erase the GPP-1.10 pkg. Until erased yum says "nothing to do" for some reason. I saw the source code in GPP-debuginfo but did not notice the executable in GPP-2.0.0 since it was all caps and looked like the directory.
In CentOS 6.5 I would like to install Google Chrome, but I am having a problem with that.
I read that this is mainly because Google are using very recent Linux build systems which produce backwards-incompatible binaries.
1) Enable Google YUM repository:
Add following to /etc/yum.repos.d/google.repo file:
for 32-bit
[google]
name=Google - i386
baseurl=http://dl.google.com/linux/rpm/stable/i386
enabled=1
gpgcheck=1
gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub
for 64-bit
[google64]
name=Google - x86_64
baseurl=http://dl.google.com/linux/rpm/stable/x86_64
enabled=1
gpgcheck=1
gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub
2) Install Google Chrome with YUM (as root user)
yum install google-chrome-stable
Copy and run this line :
curl https://intoli.com/install-google-chrome.sh | bash
Whilst adding a Google Chrome repo works in CentOS 7, the original question mentioned CentOS 6.5, so just a yum repo on its own isn't good enough for that older (but still supported) platform.
Google do indeed use far too "new" compiler tools when building their Google Chrome browser on Linux, resulting in quite frankly avoidable libstdc++ compatibility issues in CentOS 6. The correct answer is to download and run the script I wrote from the site http://chrome.richardlloyd.org.uk/ but note that you must upgrade to at least CentOS 6.6 to run it.
This installs Chrome on any RHEL/CentOS/Amazon Linux variant.
curl https://intoli.com/install-google-chrome.sh | bash
Refer for more details: https://intoli.com/blog/installing-google-chrome-on-centos/
For linux rpms, you can find specific versions of Chrome here:
https://dl.google.com/linux/rpm/stable/x86_64/google-chrome-stable-CHROME_VERSION.x86_64.rpm
replace CHROME_VERSION with the version you are looking for, e.g. 86.0.4240.198-1
I'm trying to install plone 4.3.4 on a SLES 11 SP3 64bit server via the Unified Installer. I've fullfilled all the dependencies listed in the readme.txt, but when I try to get the installer running with the command sudo ./install.sh --password=******* standalone I get the error message: which: no python2.7 in (/usr/bin:/bin:/usr/sbin:/sbin) Unable to find python2.7 on system exec path.
I find that rather strange as in the description of the unified installer it is said "The new Zope/Plone install will use its own copy of Python, and the Python installed by the Unified Installer will not replace your system's copy of Python. You may optionally use your system (or some other) Python, and the Unified Installer will use it without modifying it or your site libraries." on the Plone-Website.
So - what am I doing wrong???
I've just tried adding the parameter --build-python but had to find out that the libxml2-devel and libxslt-devel libraries that are available for SLES-11-SP-3 are sadly not up-to-date enough 2.7.6 instead of 2.7.8 and 1.1.24 instead of 1.1.26 respectively. So no joy there either. :-(
Is there any way to install the current version of plone on SLES 11 SP3 64bit?
Kate
The installer command:
./install.sh standalone --build-python --static-lxml=yes
worked perfectly for me. The installer downloaded and built the Python and libxml2/libxslt components necessary to remedy the terribly out-of-date (and vulnerable) versions included with sles11sp3.
System packages needed for the build were:
gcc-c++
make
readline-devel
libjpeg-devel
zlib-devel
patch
libopenssl-devel
libexpat-devel
man
All installed via zypper.
I'd advise not using sudo for the install. If you want to, you'll need to create the plone_daemon and plone_buildout users and the plone_group group in advance due to oddities in SUSE's adduser implementation.
I have installed OpenSUSE 12.1 installed on machine.
and i have postgresql-contrib-8.3.11-0.1.i586.rpm,postgresql-devel-8.3.11-0.1.i586.rpm, postgresql-docs-8.3.11-0.1.i586.rpm,postgresql-libs-8.3.11-0.1.i586.rpm,postgresql-server-8.3.11-0.1.i586.rpm..
I want to installed postgresql 8.3 version based on above packages..but when i installed with this command .it shows an error.
opnsu121:/ # rpm -Uvh postgresql-server-8.3.11-0.1.i586.rpm
error: Failed dependencies:
postgresql = 8.3 is needed by postgresql-server-8.3.11-0.1.i586
Even i am not able to find postgresql 8.3 base version as i think the above one is update.i have gone throgh the download.openSUSE.orf,ftp.openSUSE.org..
http://download.opensuse.org/update/11.0/rpm/i586/..
but not able to find what i need..so please help on this,
If at all possible, use YaST or whatever package manager SuSE uses to install the current version of PostgreSQL. From the repository it looks like that's 9.1.1.
If you specifically need PostgreSQL 8.3, I'd recommend using the distro-independent installer from EnterpriseDB. That should work fine on SuSE 12.2. If your organisation has particularly restrictive and unsafe version policies that force you to use old versions with known bugs, you can get 8.3.14 for 32-bit Linux here and 8.3.11 for 32-bit Linux here.
If you have issues with using the well-tested and known-to-work EnterpriseDB binary installer versions of PostgreSQL, your other option (and a good one) is to install from source code. Download the PostgreSQL 8.3.18 sources from the FTP site, then:
sudo mkdir -p /opt/postgresql93
sudo chown `id -un` /opt/postgresql93
./configure --prefix=/opt/postgresql93
make
make install
after which you can use /opt/postgresql93/bin/initdb (see initdb manual) to create a database and /opt/postgresql93/bin/pg_ctl (see pg_ctl manual) to start/stop it, as per the PostgreSQL documentation.
Don't try to force packages from an old version of SuSE to install on your new version. It'll probably result in an increasing tree of dependencies and end in pain.
If at all possible, try to convince your company that their policy of requiring a specific minor version (eg 8.4.14 not just "8.4.x") of PostgreSQL is unsafe and counterproductive. They're forcing you to do dirty hacks or hand-compile unique, custom installs just for your setup in order to avoid using well tested builds that contain extra bug fixes. Requiring approval before upgrading from 8.3 to 8.4/9.0/9.1/etc makes sense as there are feature and backward compatibility changes that require careful testing, but requiring approval before upgrading from 8.3.14 to 8.3.18 is counterproductive. Minor version upgrades of PostgreSQL are very conservative; you should stay up to date with the latest minor release.
hurray...I got the answer..
I have got the package below:
postgresql-contrib-8.3.11-0.1.i586.rpm, postgresql-devel-8.3.11-0.1.i586.rpm,postgresql-docs-8.3.11-0.1.i586.rpm,postgresql-libs-8.3.11-0.1.i586.rpm,postgresql-server-8.3.11-0.1.i586.rpm from the below link:
http://download.opensuse.org/update/12.1/i586/
and the one more package which i have struggled to get is:
postgresql-8.3.11-0.1.i586.rpm with the following link:
http://rpm.pbone.net/index.php3/stat/4/idpl/17194424/dir/opensuse_11.x/com/postgresql-8.3.11-0.1.i586.rpm.html
with all above packages i have installed using..
rpm -ivh packagename
if there is a dependency then rpm -ivh --nodeps packagename
great..its done..
I really enjoy Chrome, and the sheer exercise of helping a port would boost my knowledge-base.
Where do I start?
What are the fundamental similarities and differences between the code which will operated under Windows and Linux?
What skills and software do I need?
Note:
The official website is Visual Studio oriented!
Netbeans or Eclipse are my only options.
I will not pay Microsoft to help an Open Source project.
EDIT: (2/6/10)
A Beta version of Chrome has been released for Linux. Although it is labeled beta, it works great on my Ubuntu box. You can download it from Google:
http://www.google.com/chrome?platform=linux
EDIT: (5/31/09)
Since I answered this question, there have been more new developments in Chrome (actually "Chromium") for Linux: An alpha build has been released. This means it's not fully functional.
If you use Ubuntu, you're in luck: add the following lines to your /etc/apt/sources.list
deb http://ppa.launchpad.net/chromium-daily/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/chromium-daily/ppa/ubuntu jaunty main
Then, at the command line:
aptitude update
aptitude install chromium-browser
Don't forget to s/jaunty/yourUbuntuVersion/ if necessary. Also, you can s/aptitude/apt-get/, if you insist.
And.... Yes, it works. I'm typing this in my freshly installed Chromium browser right now!
The build is hosted by launchpad, and gave me some security warnings upon install, which I promptly ignored. Here's the website: https://launchpad.net/~chromium-daily/+archive/ppa
The original answer:
Linux Build Instructions
Read this article on Chrome and Open Source on Linux:
http://arstechnica.com/journals/linux.ars/2008/09/02/google-unveils-chrome-source-code-and-linux-port
The Google V8 JavaScript Engine is also open source and available here if you want to contribute;
http://code.google.com/p/v8/
If you want to contribute on Chronium, here are the instructions:
http://dev.chromium.org/developers/contributing-code
Chromium is an open-source browser
project that aims to build a safer,
faster, and more stable way for all
Internet users to experience the web.
This site contains design documents,
architecture overviews, testing
information, and more to help you
learn to build and work with the
Chromium source code.
Here is how you can get started:
http://dev.chromium.org/developers/how-tos/getting-started
EDIT: Two more questions was added to the original question.
Building on Linux requires the following software:
Subversion >= 1.4
pkg-config >= 0.20
Python >= 2.4
Perl >= 5.x
gcc/g++ >= 4.2
bison >= 2.3
flex >= 2.5.34
gperf >= 3.0.3
libnss3-dev >= 3.12
On Ubuntu 8.04, you can fetch all of the above as follows:
$ sudo apt-get install subversion pkg-config python perl g++ bison flex gperf libnss3-dev
Note: There is no working
Chromium-based browser on Linux.
Although many Chromium submodules
build under Linux and a few unit tests
pass, all that runs is a command-line
"all tests pass" executable.
