I tried to install an LDAP server on arch linux. I followed the procedure from the arch linux wiki : https://wiki.archlinux.org/index.php/OpenLDAP.
At the point slaptest -f /etc/openldap/slapd.conf -F /etc/openldap/slapd.d/, it fails with the error :
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
LANGUAGE = "",
LC_ALL = (unset),
LANG = "en_US.UTF-8"
are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
58130d8d mdb_db_open: database "dc=example,dc=com" cannot be opened: No such file or directory (2). Restore from backup!
58130d8d backend_startup_one (type=mdb, suffix="dc=example,dc=com"): bi_db_open failed! (2)
slap_startup failed (test would succeed using the -u switch)
On the website there stands if you do not have a database yet, you might need to create one by starting and stopping the slapd.service using systemd ) but how do I do this? And dose this solve the error?
How can I get this right?

I am trying to use the SSHOperator to SSH into a remote machine and run an external application through the command line. I have setup the SSH connection via the admin page.
This section of code is used to define the commands and the SSH connection to the external machine.
sshHook = SSHHook(ssh_conn_id='remote_comp')
command_1 ="""
cd /files/232-065/Rans
bash run.sh
"""
Where 'run.sh' runs the shell script:
#!/bin/sh
starccm+ -batch run_export.java Rans_Model.sim
Which simply runs the commercial software starccm+ with some options I have specified.
This section defines the task:
inlet_profile = SSHOperator(
task_id='inlet_profile',
ssh_hook=sshHook,
command=command_1
)
I have confirmed the SSH connection works by giving a simple 'ls' command and checking the output.
The error that I get is:
bash run.sh, error: run.sh: line 2: starccm+: command not found
The command in 'run.sh' works when I am logged into the machine (it does not require a GUI). This makes me think that there is a problem with the SSH session and it is not the same as the one that Apache Airflow logs into, but I am not sure how to solve this problem.
Does anyone have any experience with this?
There is no issue with SSH connection (at least from the error message). However, the issue is with starccm+ installation path.
Please check the installation path of starccm+ .
Check if the installation path is part of $PATH env variable
$ echo $PATH
If not, then install it in the standard locations like /bin or /usr/bin etc (provided they are included in $PATH variable), or export the installed director into PATH variable like this,
$ export PATH=$PATH:/<absolute_path>
It is not ideal but if you struggle with setting the path variable you can run starccm stating the full path like:
/directory/where/star/is/installed/starccm+ -batch run_export.java Rans_Model.sim
I'm trying to use the Remote-SSH extension to edit files on a Linux server from my Windows 10 development machine. Normally, I log into the server using VNC and edit files locally OR I use WinSCP to pull the files to my development machine and copy them back over when done. The Remote-SSH extension seems to be the answer to this inefficiency.
I can SSH just fine using Putty or using Git Bash, but Remote-SSH fails to connect. There's some hints in the error message, but I'm not sure how to interpret them.
Here is my SSH config file (redacted) and the error I receive (redacted):

VSCode Remote-SSH error
There are there are three ways you can try. I know the problem is annoying.
Check your vscode is local window or remote window. Then, check
remote-ssh setting. (Make sure Local Server Download is auto && Use
local Server is marked.).
Remote SSH:Path . you can switch to local ssh or git/ssh
Try to update or revert remote-ssh.(Version 0.50 can connect to server host stably, I found. This one is very useful.
Maybe you just select 'Linux' instead of 'Windows' though you are using Windows when you got the option to select Linux, Windows or Mac.
Since you are connecting to a server and not your own computer, the type of server you are connecting to is most likely Linux.

I followed this website(http://www.ibm.com/developerworks/cloud/library/cl-ldap-keystone/)
I am assuming the above snippet is from a file written in shell script. Your example looks Ok.
I checked the link you provided and noted that the line you say failed is written in the IBM example as:
KEYSTONE_IDENTITY_BACKEND = ldap
Which is not legal sh (or bash) and would cause the error message you described.
KEYSTONE_IDENTITY_BACKEND = ldap
-bash: KEYSTONE_IDENTITY_BACKEND: command not found
I suspect you copied and pasted the bad example from the link into your localrc file, which caused the error you saw, but somehow when you wrote the SO question, you corrected the mistake by removing the spaces around the "=".

Full Description
I installed devstack on Centos7 (using the Devstack Quick Start Guide):
git clone https://git.openstack.org/openstack-dev/devstack
cd devstack
./stack.sh
I entered passwords as prompted, but eventually it failed with the error:
Error: pg_config executable not found.
Please add the directory containing pg_config to the PATH
or specify the full executable path with the option:
python setup.py build_ext --pg-config /path/to/pg_config build ...
or with the pg_config option in 'setup.cfg'.
I traced the problem to a limited PATH in the sudoers entry, and because my postgreSQL install is in a non-standard location, I linked pg_config into /usr/local/bin and ran stack.sh again:
sudo ln -s /usr/pgsql-9.3/bin/pg_config /usr/local/bin/pg_config
./stack.sh
(You probably won't have to do this if Postgres is in a standard location).
Install took a long time -

I killed the devstack session and did it all again with a clean git repo and with a localrc file.
./unstack.sh
cd ..
git clone https://git.openstack.org/openstack-dev/devstack
cd devstack
cat << __EOF > local.conf

This time there were no password prompts, so the local config was definitely read.
I am on Windows 7 - Sourcetree 1.4.1.0 - Embedded Mercurial 2.6.1
Target is a private mercurial repo hosted on bitbucket.
How do I enable SSH compression so that my transactions are faster?
A quick Google search yielded this document:
Edit the Mercurial global configuration file (~/.hgrc). Add the following line to the UI section:
ssh = ssh -C
When you are done the file should look similar to the following:
[ui]
# Name data to appear in commits
username = Mary Anthony <manthony#atlassian.com>
ssh = ssh -C
On Windows, the Mercurial settings file is located here:
C:\Users\{username}\AppData\Local\Atlassian\SourceTree\hg_local\Mercurial.ini
The contents of the file are actually not to be changed, as its header explains:
; System-wide Mercurial config file.
;
; !!! Do Not Edit This File !!!
;
; This file will be replaced by the installer on every upgrade.
; Editing this file can cause strange side effects on Vista.
;
; http://bitbucket.org/tortoisehg/stable/issue/135
;
; To change settings you see in this file, override (or enable) them in
; your user Mercurial.ini file, where USERNAME is your Windows user name:
;
; XP or older - C:\Documents and Settings\USERNAME\Mercurial.ini
; Vista or later - C:\Users\USERNAME\Mercurial.ini
I don't have a Mac, so I can't test this, but this Atlassian answer states that the location of this file for Mac is:
/Applications/SourceTree.app/Contents/Resources/mercurial_local/hg_local/
In my case, I'm using TortoiseHg, but the concept should be the same.
Here is my original c:\somerepo\.hg\hgrc file:
[paths]
default = ssh://hg#bitbucket.org/someuser/somerepo
So what's happening with ssh? Let's debug a pull statement, hg pull --debug on the command-line. I noticed it is running C:\Program Files\TortoiseHg\lib\TortoisePlink.exe instead of ssh to make the call:
PS C:\somerepo> hg pull --debug
pulling from ssh://hg#bitbucket.org/someuser/somerepo
running "C:\Program Files\TortoiseHg\lib\TortoisePlink.exe" -ssh -2 hg#bitbucket.org "hg -R someuser/somerepo serve --stdio"
sending hello command
sending between command
abort: no suitable response from remote hg!
So let's just reuse the call, add compression (yay!), non-interactive (batch) and our key:
[paths]
default = ssh://hg#bitbucket.org/someuser/somerepo
[ui]
ssh = "C:\Program Files\TortoiseHg\lib\TortoisePlink.exe" -ssh -2 -C -batch -i "c:\keys\somekey.ppk"
I am using the default Apache installation that comes with Snow Leopard and I have some things installed like MySQL, Rudix (Unix ports and packages) and Xcode.
When I type:
$ sudo apachectl start
I receive this output:
dyld: Symbol not found: _apr_dir_open$INODE64
Referenced from: /usr/local/sbin/httpd
Expected in: /usr/local/lib/libapr-1.0.dylib
in /usr/local/sbin/httpd
/usr/local/sbin/apachectl: line 78: 2023 Trace/BPT trap $HTTPD -k $ARGV
I don't know if it's related but my .bash_profile has this line (I typed it because import MySQLdb was not working in Python):
export DYLD_LIBRARY_PATH="/usr/local/mysql/lib/:$DYLD_LIBRARY_PATH"
If I tick Web Sharing using System Preferences the Apache starts and work, but I wan't to start it using the terminal, maybe I am forgot to pass important arguments to the apachectl command.
The Web Sharing option of System Preferences enables the Apple-supplied Apache. Its apachectl is /usr/sbin/apachectl. You appear to have installed another version of Apache in /usr/local; note the /usr/local/sbin/apachectl path. So you are not using the Apple-supplied Apache installation when you are running from the terminal and the version you are using appears to not have been installed correctly. One way to ensure you are using the Apple-supplied Apache is to specify the full path:
$ sudo /usr/sbin/apachectl start
