openssh - Reading from a file - linux

In the openssh code (openssh-5.9p1/auth2.c) in the function
input_userauth_request(int type, u_int32_t seq, void *ctxt)
I'm trying to read my own file (tried using fopen, fread) but fopen fails with an error saying No such file or directory. The file exists with full permissions. Thanks.

This function is called during in pre-authentication child (before authentication), which is chrooted in /var/empty/sshd/ (Fedora/RHEL). This is the reason why it can not find your file.
If you want it to find that file, you might disable UsePrivilegeSeparation option in sshd_config NOT RECOMMENDED IN PRODUCTION!!!. Read a bit more about privilege separation in openssh.

Sybase 16 startserver failed due to missing libsapcrypto.so

We've installed Sybase 16 Express in our Linux box, it was able to startup right after the installation. When we recently try restarting it with the startserver -f RUN_FILE command, it failed to find the libsapcrypto.so file.
~/sap/ASE-16_0/bin> ../sap/ASE-16_0/bin/dataserver: error while loading shared libraries: libsapcrypto.so: cannot open shared object file: No such file or directory
We searched this file, multiple matches presented in the following paths:
./DM/OCS-16_0/lib3p/libsapcrypto.so
./DM/OCS-16_0/lib3p64/libsapcrypto.so
./DM/OCS-16_0/devlib3p64/libsapcrypto.so
./DM/OCS-16_0/devlib3p/libsapcrypto.so
./DM/REP-16_0/lib64/libsapcrypto.so
./DataAccess/ODBC/lib/libsapcrypto.so
./DataAccess64/ODBC/lib/libsapcrypto.so
./OCS-16_0/lib3p/libsapcrypto.so
./OCS-16_0/lib3p64/libsapcrypto.so
./OCS-16_0/devlib3p64/libsapcrypto.so
./OCS-16_0/devlib3p/libsapcrypto.so
Since this hasn't been answered yet, running this command worked for me:
. /opt/sap/SYBASE.sh
Note the different syntax to make sure the environment variables are set in the terminal session, as opposed to using this syntax:
/opt/sap/SYBASE.sh

Python yagmail authentication configuration

I'm trying to setup yagmail with an external .yagmail file with credentials but when I run the code it returns
YagInvalidEmailAddress: Emailaddress "yagmail.register('my.username#gmail.com', 'my.password')" is not valid according to RFC 2822 standards
the .yagmail file is like this
yagmail.register('my.username#gmail.com', 'my.password')
Any suggestion?
You should run the following once in python, which will store the registration in the backend (yagmail.register is just a wrapper around keyring lib functionality):
import yagmail
yagmail.register(email, pwd)
After this, you can just use the following in your script to start using yagmail:
yag = yagmail.SMTP(email)
yag.send()
If you want to omit the email as well, you can write your gmail address in the .yagmail file, which should reside in you $HOME directory.
Then, you could just use:
yag = yagmail.SMTP()
yag.send()
On some systems (CentOS for me), you also need to pip install keyrings.alt and import keyrings in your registration script.

Win10: ASDF can't load system (ASDF_OUTPUT_TRANSLATION error)

Update 2
I think #faré is right, it's an output translation problem.
So I declared the evironment variable ASDF_OUTPUT_TRANSLATIONS and set it to E:/. Now (asdf:require-system "my-system") yields a different error: Uneven number of components in source to destination mapping: "E:/" which led me to this SO-topic.
Unfortunately, his solution doesn't work for me. So I tried the other answer and set ASDF_OUTPUT_TRANSLATIONS to (:output-translations (t "E:/")). Now I get yet another error:
Invalid source registry (:OUTPUT-TRANSLATIONS (T "E:/")).
One and only one of
:INHERIT-CONFIGURATION or
:IGNORE-INHERITED-CONFIGURATION
is required.
(will be skipped)
Original Posting
I have a simple system definition but can't get ASDF to load it.
(asdf-version 3.1.5, sbcl 1.3.12 (upgraded to 1.3.18 AMD64), slime 2.19, Windows 10)
What I have tried so far
Following the ASDF manual: "4.1 Configuring ASDF to find your systems"
There it says:
For Windows users, and starting with ASDF 3.1.5, start from your
%LOCALAPPDATA%, which is usually ~/AppData/Local/ (but you can ask in
a CMD.EXE terminal echo %LOCALAPPDATA% to make sure) and underneath
create a subpath config/common-lisp/source-registry.conf.d/
That's exactly what I did:
Echoing %LOCALAPPDATA% which evaluates to C:\Users\my-username\AppData\Local
Underneath I created the subfolders config\common-lisp\source-registry.conf.d\ (In total: C:\Users\my-username\AppData\Local\config\common-lisp\source-registry.conf.d\
The manual continues:
there create a file with any name of your choice but with the type conf, for instance 50-luser-lisp.conf; in this file, add the following line to tell ASDF to recursively scan all the subdirectories under /home/luser/lisp/ for .asd files: (:tree "/home/luser/lisp/")
That’s enough. You may replace /home/luser/lisp/ by wherever you want to install your source code.
In the source-registry.conf.d folder I created the file my.conf and put in it (:tree "C:/Users/my-username/my-systems/"). This folder contains a my-system.asd.
And here comes the weird part:
If I now type (asdf:require-system "my-system") in the REPL I get the following error:
Can't create directory C:\Users\my-username\AppData\Local\common-lisp\sbcl-1.3.12-win-x86\C\Users\my-username\my-systems\C:\
So the problem is not that ASDF doesn't find the file, it does -- but (whatever the reason) it tries to create a really weird subfolder hierarchy which ultimately fails because at the end it tries to create the folder C: but Windows doesn't allow foldernames containing a colon.
Another approach: (push path asdf:*central-registry*)
If I try
> (push #P"C:/Users/my-username/my-systems/" asdf:*central-registry*)
(#P"C:/Users/my-username/my-systems/"
#P"C:/Users/my-username/AppData/Roaming/quicklisp/quicklisp/")
> (asdf:require-system "my-system")
I get the exact same error.
I don't know what to do.
Update
Because of the nature of the weird path ASDF was trying to create I thought maybe I could bypass the problem by specifying a relative path instead of an absolute one.
So I tried
  (:tree "\\Users\\my-username\\my-systems")
in my conf file. Still the same error.
Ahem. It looks like an output-translations problem.
I don't have a Windows machine right now, but this all used to work last time I tried.
Can you setup some ad hoc output-translations for now that will make it work?

Sourcing Puppet files from outside of modules

I'm installing a package from a module (Nginx in this specific case) and would like to include a configuration file from outside of the module, i.e. from a top level files directory parallel to the top level manifests directory. I don't see any way to source the file though without including it in a module or in my current Vagrant environment referring to the absolute local path.
Does Puppet allow for sourcing files from outside of modules as described in the documentation?
if I understand your question correctly, you can.
In your module a simple code like this
file { '/path/to/file':
ensure => present,
source => [
"puppet:///files/${fqdn}/path/to/file",
"puppet:///files/${hostgroup}/path/to/file",
"puppet:///files/${domain}/path/to/file",
"puppet:///files/global/path/to/file",
],
}
will do the job. The /path/to/file will be sourced using a file located in the "files" Puppet share.
(in the example above, it search in 4 different locations).
update maybe you're talking about a directory to store files which is not shared by Puppet fileserver (look at http://docs.puppetlabs.com/guides/file_serving.html), and in this case you can't i think, Vagrant or not, but you can add it to your Puppet fileserver to do it. I thinks it's the best (and maybe only) way to do it.
If you have a number of Vagrant VMs you can simply store files within your Vagrant project directory (containing your VagrantFile).
This directory is usually available to all VMs as /vagrant within the VM on creation.
If you want other directories on your computer to be available to your VMs just add the following to your VagrantFile
# see http://docs.vagrantup.com/v1/docs/config/vm/share_folder.html
config.vm.share_folder "v-packages", "/vagrant_packages", "../../dpkg"
Then to use the files within puppet you can simply treat them as local files to the VM
# bad example, bub basically use 'source => 'file:///vagrant/foo/bar'
file { '/opt/cassandra':
ensure => directory,
replace => true,
purge => true,
recurse => true,
source => 'file:///vagrant/conf/dist/apache-cassandra-1.2.0',
}
This is probably only wise to do if you only using local puppet manifests/modules.
Probably too late to help bennylope, but for others who happen across this question, as I did before figuring it out for myself ...
Include stuff like this in your Vagrantfile ...
GUEST_PROVISIONER_CONFDIR = "/example/destination/path"
HOST_PROVISIONER_CONFDIR = "/example/source/path"
config.vm.synced_folder HOST_PROVISIONER_CONFIDIR, GUEST_PROVISIONER_CONFDIR
puppet.options = "--fileserverconfig='#{GUEST_PROVISIONER_CONFDIR}/fileserver.conf'"
Then make sure /example/source/path contains the referenced fileserver.conf file. It should look something like ...
[foo]
path /example/destination/path
allow *
Now, assuming example-file.txt exists in /example/source/path, the following will work in your manifests:
source => "puppet:///foo/example-file.txt",

Malformed url exception linux local file system

I have been trying to execute a selenium.attachFile command to upload a file-
sel.attachFile(dom_locator,"/home/xyz/Desktop/tstfl.txt");
but getting a Malformed URL Exception for the file path specified. The file is present in the linux local file system. Please help me with the proper format of the file path.
Likely what you need is
sel.attachFile(dom_locator,"file:///home/xyz/Desktop/tstfl.txt");
