I tried to get PHP4 working on WampServer, but whenever I started WampServer, the icon would go to orange but not all the way to green, because Apache wasn't starting.
I've explained how I got it working below. Hopefully this helps someone.
Here's how I got it working:
Install PHP 4.4.9 from http://www.wampserver.com/en/#addons-php
Install Apache 2.0.63 from http://www.wampserver.com/en/#addons-apache
Left click the WampServer tray icon, then Apache→Version→2.0.63, wait a minute, then PHP→Version→4.4.9
Test Apache by opening the command line and running C:\wamp\bin\apache\Apache2.0.63\bin\apache.exe. Fix any error reported, and repeat until you don't get any errors.
Icon→Apache→Service→Install Service
Icon→Restart All Services
In my case, the Apache errors were:
Syntax error on line 22 of C:/wamp/alias/phpmyadmin.conf: The specified IP address is invalid.
Syntax error on line 22 of C:/wamp/alias/sqlbuddy.conf: The specified IP address is invalid.
Syntax error on line 22 of C:/wamp/alias/webgrind.conf: The specified IP address is invalid.
The lines with errors were all the same: Allow from ::1. I commented them out to #Allow from ::1, which seemed to fix the error.
If you have trouble switching back to php5:
Open C:\Wamp\bin\php\php5.4.16\wampserver.conf.
Add the following lines:
$phpConf['apache']['2.4']['LoadModuleName'] = 'php5_module';
$phpConf['apache']['2.4']['LoadModuleFile'] = 'php5apache2_4.dll';
$phpConf['apache']['2.4']['AddModule'] = '';
Exit WampServer then start it again.

After booting SWUpdate yocto-generated image for the first time, executing swupdate results in error message:
Error parsing configuration file: 'globals' section missing, exiting.
I tried to strictly follow SWUpdate's documentation, but it gets short when it comes to yocto integration. I'm using meta-swupdate, meta-swupdate-boards, and meta-openembedded layers together with poky example repository all at Kirkstone tag, building via bitbake update-image and having modyfied local.conf as:
MACHINE ??= "raspberrypi4-64"
ENABLE_UART = "1"
RPI_USE_U_BOOT = "1"
IMAGE_FSTYPES = "wic ext4.gz"
PREFERRED_PROVIDER_u-boot-fw-utils = "libubootenv"
IMAGE_INSTALL:append = " swupdate"
Is there anything else I need to modify to generate the configuration file and be able to run SWUpdate binary properly?
Side question: In the documentation, it's recommended to append swupdate-www to achieve a better web server. However, if I append it, there is no swupdate-www binary inside the `/usr/bin' directory.
As with other recipes folders the recipes-support/swupdate/swupdate/raspberrypi4-64 folder was missing inside the meta-swupdate-boards layer. Therefore, an empty config file was always generated. After adding this folder and all related files, strongly inspired by raspberrypi3 folder, the error was gone and swupdate -h provided the expected output.
There was also one new error during build process thrown by yocto. It was related to missing systemd requirement and was solved by adding:
DISTRO_FEATURES_append = " systemd"
to local.conf
I have met with a strange issue in running R notebooks in zeppelin(0.7.2).
Spark intrepreter is in per note Scoped mode and spark version is 1.6.2 and SPARK_HOME is set.
Please find the steps below to reproduce the issue:
Create a notebook (Note1) and run any r code in a paragraph. I ran the following code.
%r
rdf <- data.frame(c(1,2,3,4))
colnames(rdf) <- c("myCol")
sdf <- createDataFrame(sqlContext, rdf)
withColumn(sdf, "newCol", sdf$myCol * 2.0)
Create another notebook (Note2) and run any r code in a paragraph. I ran the same code as above.
Till now everything works fine.
Create third notebook (Note3) and run any r code in a paragraph. I ran the same code. This notebook fails with the error
org.apache.zeppelin.interpreter.InterpreterException: sparkr is not
responding
What I understood from the analysis is that the process created for sparkr interpreter is not getting killed properly and this makes every third model to throw an error while executing. The process will be killed on restarting the sparkr interpreter and another 2 models could be executed successfully. ie, For every third model run using the sparkr interpreter, the error is thrown.
Help me to fix the problem.
you need to set spark.r.numRBackendThreads larger than 2. By default it is 2 which means you can only have 2 threads for RBackend. Since you are using scoped mode per note, each note will consume one thread for RBackend, so you can only run 2 note.
I am working on a remote red-hat server and there I'm developing a c application to insert data in to a remote oracle database. So first i installed the OCI instant client rpm on the server and tried to compile a sample program. after certain linkages I could compile it. But then when I am going to run it. It exits giving an error saying
ORA-12162: TNS:net service name is incorrectly specified
The sample code I used is from the blog (refer to this code in case you need to clarify the things.where I’m quoting only few pieces to this post) René Nyffenegger's collection of things on the web
René Nyffenegger on Oracle
(refer to this code in case you need to clarify the things.where I’m quoting only few pieces to this post)
In the code I added some prints to check for the error And it seems like It gets stuck in the OCIServerAttach() function r gives a printed walue of -1
r=OCIServerAttach(srv, err, dbname, strlen(dbname), (ub4) OCI_DEFAULT);
printf("r value %d",r);
if (r != OCI_SUCCESS) {
checkerr(err, r);
goto clean_up;
}
Another point is that in the compilation process it gives a warning saying that a certain libry is not include. but the exicutable file is created. Here is the massage I get in the compilation process.
[laksithe#loancust ~]$ gcc -L$ORACLE_HOME/lib/ -L$ORACLE_HOME/rdbms/lib/ -o oci_test oci_test.o -L/usr/lib/oracle/12.1/client64/lib -lclntsh `cat $ORACLE_HOME/lib/sysliblist`
cat: /lib/sysliblist: No such file or directory
Going through the web I found that by creating a tnsnames.ora file with the connection details I could solve the problem. But even It didn't work for me. Here is the link for that blog blog
It has been a week since this error and I cold'nt solve it. could someone please help me.
connection string format I used is abc.ghi.com:1521/JKLMN
My recommendation is to bypass tnsnames completely. Oracle has always allowed you to put in the direct connection details, but EZConnect makes that even easier.
When you format your connection string, instead of listing the TNS name, use the actual connection properties in the following format:
servername:port/service name
For Example
MyOracle.MyCompany.Com:1521/SalesReporting
Your connection string might also require direct=true, but I'm honestly not sure.
I like the idea of tnsnames, but it's a double edged sword. When it works, it's great. When it doesn't, you want to throw something. With EZConnect, it always works.
By the way, if you don't know the properties of the three items above, find a machine that connect via tnsnames and:
tnsping <your TNS-named database>
I'm trying to retrieve a file from an instance using libssh2 scp.
Just to make sure that my username, password, and keys are correct, I did:
sudo scp -v -P #port -i /home/username/.ssh/id_rsa username#XX.XX.XX.XX:/home/username/file .
Which asked me for the password, and then retrieved the file successfully.
In trying to accomplish the same thing with libssh2, I followed the example here:
http://www.libssh2.org/examples/scp.html
With superficial changes to variable types that seem to have since changed
(Not that it should matter, as those variables come after authentication).
However, on
libssh2_userauth_publickey_fromfile(session, username,"/home/username/.ssh/id_rsa.pub","/home/username/.ssh/id_rsa",password)
The program always exits with a LIBSSH2_ERROR_PUBLICKEY_UNVERIFIED.
Checking using gdb, I'm certain that the username and passwords being applied are correct.
What reasons might there be that are causing this problem?
Edit:
Further delving with GDB reveals that somewhere in the depth of libssh2_userauth_publickey_fromfile(), in _libssh2_userauth_publickey(session, username, username_len, pubkeydata, pubkeydata_len, sign_callback, abstract), it receives a LIBSSH2_ERROR_SOCKET_RECV.
The code behind that, however, is much too enigmatic for my untrained eye to make sense of.
One obvious thing I've missed is the error message, which comes out to be "Waiting for USERAUTH response"
Potentially relevant:
https://github.com/nodegit/nodegit/issues/553
After following what little advice I could gather from above link and removing a few keys from authorized_keys, the error remains the same but the message changed to "Callback returned error". Not sure if improvement or worse.
Checking server-side logs, I find the following:
Oct 20 06:53:51 testbed1 sshd[25837]: error: Could not load host key: /etc/ssh/keyname
Oct 20 06:53:52 testbed1 sshd[25837]: Connection closed by XX.XX.XX.XX [preauth]
Oct 20 06:54:48 testbed1 sshd[25839]: error: Could not load host key: /etc/ssh/keyname
Oct 20 06:54:51 testbed1 sshd[25839]: Accepted publickey for username from...
The first two lines are on a failed attempted from libssh2.
The next two lines are on a successful attempt from scp on commandline.
I'm still not absolutely sure what is the cause.
I can only speculate that I had fallen into the bug described here:
cURL sftp public key authentication fails "Callback Error"
The code ran fine on a key without passphrase.
I still have a hard time saying this is the exact solution, as when I had just started using libssh2, it ran fine with keys with passphrase.
Still, it "works" now.
Summary: Unable to run any of the most simple “Hello World” FastCGI script, any request always terminating into a time out. Seems there is no communication at all between the server and the FastCGI scripts (using dynamic FastCGI scripts).
The environment
Ubuntu Precise (12.04)
Package apache2.2-bin
Package apache2-mpm-prefork
Package libapache2-mod-fastcgi
Package libfcgi-perl
Package python-flup
Multiple sites configured as virtual hosts on 127.0.0.1
There exists a /var/lib/apache2/fastcgi directory, owned by www-data, readable by all (owner, group and others)
There exists a /var/lib/apache2/fastcgi/dynamic directory, owned by www-data, which is restricted to the owner (readable, writable and accessible by www-data only)
There exists an inode/socket file in the /var/lib/apache2/fastcgi/ directory
The FastCGI relevant configurations:
The directory /etc/apache2/mods-enabled/ holds a reference to fastcgi.conf and fastcgi.load (mod_fastcgi is enabled).
The file fastcgi.conf contains the following (left untouched, I did not edit it):
<IfModule mod_fastcgi.c>
AddHandler fastcgi-script .fcgi
#FastCgiWrapper /usr/lib/apache2/suexec
FastCgiIpcDir /var/lib/apache2/fastcgi
</IfModule>
The relevant configuration file in /etc/apache2/sites-enabled/ contains the following (there is nothing more anywhere else about FastCGI specific configuration):
<DirectoryMatch /fcgi-bin>
Options +ExecCGI
<FilesMatch "^[^\.]+$">
SetHandler fastcgi-script
</FilesMatch>
</DirectoryMatch>
The test materials on the test virtual host:
There exist a fcgi-bin/test-perl.fcgi whose content is (the file is executable by all, and readable by owner and group):
#!/usr/bin/perl
use CGI::Fast qw(:standard);
$COUNTER = 0;
while (new CGI::Fast) {
print header;
print start_html("Fast CGI Rocks");
print
h1("Fast CGI Rocks"),
"Invocation number ",b($COUNTER++),
" PID ",b($$),".",
hr;
print end_html;
}
There exist a fcgi-bin/test-python.fcgi whose content is (the file is executable by all, and readable by owner and group):
#!/usr/bin/python
def myapp(environ, start_response):
start_response('200 OK', [('Content-Type', 'text/plain')])
return ['Hello World!\n']
try:
from flup.server.fcgi import WSGIServer
WSGIServer(myapp).run()
except:
import sys, traceback
traceback.print_exc(file=open("errlog.txt","a"))
The issue
Although both fcgi-bin/test-perl.fcgi and fcgi-bin/test-python.fcgi runs normally when executed from the command‑line, none seems to work when invoked, e.g. as http://test.loc/fcgi-bin/test-perl.fcgi or http://test.loc/fcgi-bin/test-python.fcgi.
Nothing at all happens, and after some delay, I get an Error 500, and Apache error logs contains multiple entries looking like:
[<date>] [error] [client <IP>] FastCGI: comm with (dynamic) server "/<…>/fcgi-bin/<script>.fcgi" aborted: (first read) idle timeout (30 sec), referer: <referrer>
[<date>] [error] [client <IP>] FastCGI: incomplete headers (0 bytes) received from server "<…>/fcgi-bin/<script>.fcgi", referer: <referrer>
I've spent hours and hours searching the web trying to understand why it does not work, and finally decided to give up and ask for some help here.
Any pointers and check list welcome. Feel free to ask for any missing details you may feel to be relevant or worth checking.
Enjoy a nice day.

Issue update
In my own reply to my own question, I mentioned a weird case where things were looking suddenly fine without reasons. I later discovered this was only partly fine.
In the same virtual host, so with the exact same server configuration, some scripts, which are exactly the same (and with exact same access rights), fails depending on their location.
As a remainder, here is what's in the site configuration:
<DirectoryMatch /fcgi-bin>
Options +ExecCGI
<FilesMatch "^[^\.]+$">
SetHandler fastcgi-script
</FilesMatch>
</DirectoryMatch>
With the above, only scripts in /fcgi-bin are handled as FastCGI script. But I also have some elsewhere (still for testing): one in /cgi-bin and one in / (i.e. in the public_html directory). For this purpose, .htaccess contains this entry:
Options +ExecCGI
AddHandler fastcgi-script .fcgi
So the two others FastCGI script should work the same as the one in /fcgi-bin, but they don't, and for the time, they invariably terminates with a connexion time‑out, just like the one /fcgi-bin first did.
This makes me feel something may be wrong with the mod_fastcgi module (known bug? else?). So far, this module seems to act rather randomly.
-- edit 2 --
The above in the first edit, was an error of mine: the group was wrong with the other scripts, it had to be www-data, but it was not. So is something is wrong, stick to the answer I gave, that is, try to look at the FastCgiConfig, and see if it solve anything or at least if it honours the time‑out options.
I will answer my own question, as it seems to be working now. However, the epilogue still looks weird.
Although the default configuration should be OK, I still wanted to review the “Module mod_fastcgi” document again. As I only wanted a dynamic FastCGI, I focused on the FastCgiConfig directive only, thus on purpose not going into FastCgiServer and FastCgiExternalServer directives.
As there was no FastCgiServer at all in the default fastcgi.conf file, I started to try to set‑up my own. For a first test, I wanted to use the -appConnTimeout option, at least to request the server to not wait so much long before it returns me an Error 500.
So I just added this in the site configuration (I did not touch fastcgi.cong), in the same file where virtual hosts are configured:
FastCgiConfig -appConnTimeout 2
This was to tell the server to wait no more than 2 seconds, instead of the 30 seconds it was waiting. I tried to invoked a FastCGI script to see if at least this configuration was working. I expected to get an error in a 2 seconds delay, but instead, the script ran without error.
What's weird, is that I then tried to remove this option, to check if it was just that addition which was just missing to make FastCGI scripts working. But after I commented‑out the option, it was still working, and the same after a full reboot.
Can't tell more, that looks weird, but this is the only thing I did, I did not edit anything else. I can just suggest people who may encounter a similar issue, to just try the above.
Sorry, if I can't explain what it did exactly. I really would like to know. It just working now, but I don't know why.
