From rabbitmq documents I know there is an new_ssl application.
I have installed erlang through macport command. after using command "port content erlang|grep new_ssl", I can't find it.
In www.erlang.org, new_ssl document, it says new_ssl is an module not an application.
But reading ssl.app, it also doesn't contain new_ssl module?
Is it a ghost?
new vs old ssl are two different implementations of SSL. Old ssl used libopenssl directly where as new ssl is build in erlang with only libcryto functions in C. As of the R15B release (dec 2011) of Erlang/OTP, the old_ssl implementation was entirerly dropped.

I have a device running TwinCAT/BSD.
Following section 5 the manual for TwinCAT/BSD I have successfully managed to install the TF6250 package. After updating the firewall rules I have confirmed that I am able connect and issue modbus tcp requests successfully using the Default Configuration from section 4.3 of the TF6250 manual.
My project requires mapping that is different from the default (i.e to the %Q registers rather than %M). Normally (when not not using TwinCAT/BSD) I would be able to edit my mapping via the Modbus TCP Configurator, but there does not appear to be an equivalent tool contained in the package for TwinCAT/BSD.
I have tried copying the mapping files that I would have created in the configurator into the Server directory with no luck. Are you able to tell me how my mapping can be updated in the TwinCAT/BSD environment?
If relevant:
TwinCAT Build: 3.1.4024.19
TC/BSD: 12.2.9.1,2
TF6250-Modbus-TCP: 2.0.1.0_1
pkg repo: https://tcbsd.beckhoff.com/TCBSD/12/stable/packages
I spoke with Beckhoff support who told that TF6250 expects the xml file with the configuration here: /usr/local/etc/TwinCAT/Functions/TF6250-Modbus-TCP/TcModbusSrv.xml
I tested this and it appears to work so all you need to do;
Create the mapping file as per normal (e.g using the windows tool) and copy the file there.
Reboot the device to load the configuration from the file.

GlassFish Server update center installation times out
Java EE 7 updatetool installation fails
I got my Java EE 7 SDK (Update 3) from here: http://www.oracle.com/technetwork/java/javaee/downloads/index.html
I have tried each of the solutions in the above posts and here: https://blogs.oracle.com/dipol/troubleshooting-glassfish-update-center
Including:
In the cmd prompt running set PKG_CLIENT_CONNECT_TIMEOUT=300 and set PKG_CLIENT_READ_TIMEOUT=300 before updatetool in C:\glassfish4\bin\updatetool.bat (c:\glassfish4 in my install directory - all settings were default, including install update tool...).
Set above mentioned timeout to much larger values - doesn't appear to make a difference at all, the process basically bombs immediately.
Running C:\glassfish4\bin\updatetool.bat many times.
Triple checking that I didn't somehow configure a proxy server in my sleep.
Use the update tool via the Glassfish admin console at http://localhost:4848 (seems to show no available update or add-ons, which seems odd..)
I get the following screenshot when I run C:\glassfish4\bin\updatetool.bat
I have no idea why the error would be proxy related, unless it happened to be something on their end. Interestingly, If I go directly to the URL mentioned (via Chrome) I get the following page:
What could possibly be going wrong here?
The updatetool was a commercial feature of Oracle GlassFish. Any update functionality relied on Oracle providing a site where updates could be hosted. Since Oracle GlassFish is no longer supported, this site no longer exists so the updatetool won't work any more.
Rather than downloading GlassFish from Oracle, you should download it from the official open source site, hosted on GitHub. Alternatively, if you really do need support, you could try Payara Server which is open source, and derived from GlassFish, but has support available (disclaimer: I work for Payara)

What are the .kdb and .sth files function? If I want to generete the .sth file again, Do I need to keep the application servers (liberty) running? Where can I find more information about these files related to the IBM platform?
The *.kdb is a collection of SSL certificates and keys. It's password-protected. The *.sth is where the obfuscated password is stored.
You can recate the *.sth with the command line tools provided by IHS and the WAS plugin. See $IHSROOT/bin/gskcapicmd -keydb -stashpw.
The *.sth file has no real relationship the application server or any JVM. It's read by the WebServer Plugin at startup.
I need to use bcmath in a shared hosting that does not provide it by default. So I asked the hosting company about it and they are not going to provide it. I would have left this hosting as most of the modern hosting provide this and other features that are not provided by the current hosting. But now I just want to get the job done and not start by suggesting to my customer to leave the hosting before trying a plan B. Is it possible to get bc math in a shared hosting using .htaccess or other method? I have not been able to find anything during my search except for this http://php.net/dl, but I do not know if it applies to my case and I have not found enough information about it.

That is a compile-time option, so nothing you could set via .htaccess. If you need it, you will have to switch to a hoster/hosting package that offers it.
I am trying to fetch a file over HTTPS in Io language:
url := URL with("https://api.example.com")
url fetch println
And I get this:
Error_0x7f97e1509a80:
location = "/opt/local/lib/io/addons/Socket/io/URL.io:232"
message = "Protocol 'https' unsupported"
I was trying to find something on the net, but, as everybody knows, it's not easy because of the name. I only found this thread http://tech.groups.yahoo.com/group/iolanguage/message/10898 but that's quite old.
How can I get the HTTPS support in Io?
EDIT
I've found that there is a SecureSocket addon, a wrapper over OpenSSL, in Io's source. It wasn't installed when I did sudo port io install on my MacBook with Mountain Lion, though. I tried building it from source, but no luck. It didn't build for me on a Linux machine, either.
EDIT2
I just tried to build Io from source (git clone https://github.com/stevedekorte/io.git) again (using the included script build.sh) and it turned out that cmake did detect OpenSSL:
-- Found OpenSSL: /usr/lib/libssl.dylib;/usr/lib/libcrypto.dylib
But then the SecureSocket addon is not built. Its readme file: https://github.com/stevedekorte/io/tree/master/addons/SecureSocket says:
The DTLS1 bindings are not usable unless the patches in this file are
applied to OpenSSL 0.9.8e. However, this patch includes a
deactivation of the handshake retransmission code in d1_both.c,
making it unsuitable for production environments. I take no
responsibility, etc, etc. If you want to use it anyway, apply the
patches(gathered from various newsgroups and my own experimentation)
and uncomment the commented-out block of build.io. For what it's
worth, DTLS support in OpenSSL is new as of 0.9.8 and is pretty buggy
to begin with. It's a nice idea, but it doesn't seem to be
production ready at all yet. These bindings are no exception.
If you can't get io to do it your best option would be calling an external tool like wget or curl which can and then loading the file/result locally or returning it via a pipe.
For anybody else interested in another workaround, it should be possible to put stud in front of an Io program which will do the SSL stuff. I have not tested that myself yet.
stud - The Scalable TLS Unwrapping Daemon stud is a network proxy that
terminates TLS/SSL connections and forwards the unencrypted traffic to
some backend. It's designed to handle 10s of thousands of connections
efficiently on multicore machines.
