I'm playing with RISC-V.
I have a .img file and I want to disassemble it into a .asm file, so I ran the following command:
> riscv64-unknown-elf-objdump -d xxx.img > xxx.asm
However, I got this issue:
riscv64-unknown-elf-objdump: xxx.img: file format not recognized
How can I fix it? I have no idea what to do with this issue.
If you run:
riscv64-unknown-elf-objdump --help
You'll see a line like:
riscv64-unknown-elf-objdump: supported architectures: riscv riscv:rv64 riscv:rv32
These are the supported architectures that you need to pass as the -m argument. Normally, an ELF file will encode this information so there's no guesswork, but in the case of using a flat file, there's no way for objdump to know how the instructions are supposed to be interpreted. The final command is:
riscv64-unknown-elf-objdump -b binary -m riscv:rv64 -D xxx.bin
I am trying to rsync a local folder to a remote location. This a command that I have run successfully a week ago, but now if i run:
rsync -vrtzu\
--chown=user:webadm
--delete
--exclude-from=.rsyncignore
FOLDER/
USER#REMOTE:/DESTINATION
Then I get the following error message:
zsh:1: no matches found: --usermap=*:USER
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(235) [sender=3.1.3]
make: *** [makefile:39: push] Error 12
The command is run from a makefile, hence the last line.
I am using a regular WSL2 Ubuntu shell, not zsh.
I am able to ssh into the remote location with USER#REMOTE.
I have also checked that both locations have rsync installed (same version).
Finally, there is plenty of disk space available on the remote location.
Any pointers? What should I be checking to improve my diagnostic?
Thanks in advance!
This can happen when the remote shell messes with the command. Not sure exactly why and what it does but it modifies escaping so that the file path becomes invalid.
In your case the shell outputs --usermap=*:USER at log in.
The solution is to change the remote (zsh) shell to bash using the chsh command
I'm pretty sure this is an rsync bug:
zsh:1: no matches found: --usermap=*:USER
It only happens the remote machine's default shell is zsh.
It was fixed somewhere between rsync 3.2.3 (where it's broken) and 3.2.5 (where the bug is gone).
You can verify this by passing -vv to rsync. This prints as one of the first output lines which command invocation rsync is doing on the remote server via SSH.
On a broken version, it prints e.g.:
... ssh ... rsync --server -vvnlogDtpRe.LsfxCIvu "--usermap=*:user" "--groupmap=*:webadm"
On a fixed version, it prints e.g.:
... ssh ... rsync --server -vvnlogDtpRe.LsfxCIvu "--usermap=\*:user" "--groupmap=\*:webadm"
As you can see, they inserted a \ to fix the string being interpreted by zsh.
Httpd processes use a non-default configuration file if they are run with the -f flag.
For example
/home/myuser/apache/httpd-2.4.8/bin/httpd -f /confFiles/apache/2.4.8/apache.conf -k start
will use this configuration file: /confFiles/apache/2.4.8/apache.conf
I need to get this location and would rather not have to check for possible -f flags used to start httpd.
The answer here says to run /path/to/httpd -V and concatenate
-D SERVER_CONFIG_FILE="conf/httpd.conf"
with
-D HTTPD_ROOT="/etc/httpd"
to get the final path to the config file.
However, this path will not be the correct one if the -f flag is used to start the httpd process.
Is there a command that can get the config file that is actually being used by the process?
The answer you refer to mentions the paths httpd was compiled with, but as you say those can be manually changed with parameters.
The simple way to check is the command line, if process is called "httpd" (standard name), a simple ps will reveal the config file being used:
ps auxw | grep httpd
Or querying the server if server has mod_info loaded, in command line or with your favourite browser:
curl "http://yourserver.example.com/server-info?server" | grep -i "config file"
Note: mod_info should not be publicaly available for everyone to see.

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 "=".

Create a file in the root of the devstack repo, devstack/local.conf with the contents:

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

KEYSTONE_IDENTITY_BACKEND=ldap
KEYSTONE_CLEAR_LDAP=yes
LDAP_PASSWORD=9632
__EOF
./stack.sh
This time there were no password prompts, so the local config was definitely read.
I am following along in the "Apache Axis2 User's Guide - Creating Clients"
http://axis.apache.org/axis2/java/core/docs/userguide-creatingclients.html#choosingclient
My problem is when I execute the command line argument from the guide:
%AXIS2_HOME%\bin\WSDL2Java -uri Axis2UserGuide.wsdl -p org.apache.axis2.axis2userguide -d adb -s
I get the following response, I am also unsure where axis2userguide.wsdl resides in the axis2 distribution.
Caused by: javax.wsdl.WSDLException: WSDLException: faultCode=OTHER_ERROR: Unable to resolve imported document at 'Axis2UserGuide.wsdl'.: java.io.FileNotFoundException: This file was not found: file:/C:/Desktop/axis2-1.6.2/bin/Axis2UserGuide.wsdl
Is axis2userguide.wsdl a file included in the distro, or is it an arbitrary file name?
Thanks
I was able to the complete the step of creating the stub in the tutorial by doing the following:
C:\axis2-1.6.2\samples\quickstart>set CLASSPATH=%CLASSPATH%;C:\axis2-1.6.2\samples\quickstart\build\classes;
C:\axis2-1.6.2\samples\quickstart>%AXIS2_HOME%\bin\java2wsdl -cp . -cn samples.quickstart.service.pojo.StockQuoteService -of StockQuoteService.wsdl
C:\axis2-1.6.2\samples\quickstart>%AXIS2_HOME%\bin\WSDL2Java -uri StockQuoteService.wsdl -p org.apache.axis2.StockQuoteService.wsdl -d adb -s
The root cause was the file didn't exist, and my CLASSPATH wasn't set.
Hope this helps someone else.
