SIP 408 Request Timeout for Freeswitch - freeswitch

I am trying to create an account on Zoipher. Saw some articles over here regarding the configuration and setup. I have freeswitch installed on docker. I came across one similar article here where someone else is facing the same problem but that is for Asterisk. Also, they are referring to create a SIP account in sip.conf. However, I couldn't find anything existing inside my freeswitch directory where I can create a SIP account before creating it on Zoipher softphone. Please let me know

The default FreeSWITCH configuration already has users 1000 to 1019, with the password 1234. There's a directory/ folder with a bunch of XML in it.
The best and the quickest way to learn FreeSWITCH is with their book: https://www.packtpub.com/networking-and-servers/freeswitch-12
or through training (I did some training for a small team, can do that again)

You can find SIP users' accounts in the <freeswitch home directory>/conf/directory/default. There are XML files with sip accounts, inside them you can configure UserID and passwords for SIP users.

I wouldn't recommend using Docker for a VoIP server before Docker supports port ranges. You need to configure it to map UDP port ranges for RTP, and with current version of Docker you can only list every port explicitly. In the next release, they promise to support port ranges.

Working around the Windows OS limitation of not allowing multiple connections to a server/shared resource

We are building a system on windows where we centrally (server) need to do fopen to either local files or remote smb resources. The idea is to authenticate in the case of remote resources before doing fopen (with unc paths).
We need to authenticate with the credentials the user (client application) supplied for this resource on that remote share. We don't want to copy any resources.
Using the Win Net Api this works smoothly since it stores the given credentials so that subsequent fopens in the same or in different processes succeed.
But there is a problem:
Many of you probably know the following message from windows when trying to connect to a smb share with different credentials then the ones used for a previous connection:
"Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."
See http://support.microsoft.com/kb/938120 for the defined limitation and possible "work arounds".
Since we have a central server application running as a service ('Local System' account) we hit this limitation with having already two different users :).
Closing the previously established connection to allow for the 2nd one is not an option (ongoing processing).
On the one hand it's great that windows caches authentication information on the other hand it's too limited.
Modifying the hosts file for each user does not look very nice.
Using smb client libraries (like libsmb++, impacket) doesn't seem to be the solution since we need "over process" authentication.
Configuring a "master" smb share user is also not wanted.
Maybe passing windows user auth tokens around is a way?
This problem is of general nature (i.e. independent of language) and I'm convinced that there are people out there who solved it (in a more or less elegant way ;))
I hope my explanation is understandable.
Thanks in advance for any hint.

How to identify computer which I have redirected

I have the following problem to solve:
I few months ago I startet a website where you can watch youtube videos which aren't available in your country. Everythings works fine but now I want to offer a new method where I route all the requests directly over my server. Therefore I will later use a custom DNS-Server. Right now I use the hosts file for testing but I have really no idea how i can identify the user. I can promp the user user to login on a website but I will that it works systemwide so if he use a youtube downloader for example it have to work there either and not only in the browser where I could use a session system with cookies. I want a solution where the user can identify himself once in a time like a website or something like this but how can my server detect if this is a user which is logged in or if he is not?
There are several ways that this could be accomplished with varying levels of difficulty.
standard proxy server over https. Your service could simply be a proxy server and then every "client" would update their browser to point to your proxy server. You could also simplify this by using a proxy PAC file (proxy auto config).
An anonomyzing interface. The end user would not be able to use their standard search tools etc, instead they would have to use a web page much like what google translate does.
A browser plugin. There are already firefox plugins which do something similar to this. They change the way that the browser resolves DNS. This may be the best bet for you but would require development work.
An actual install utility that you have your users install on their machines which update the dns servers.

Location of crossdomain.xml Windows Azure

I need to put a crossdomain.xml file in my Windows Azure Web Role. But where ?
I tried to put it in : F:\sitesroot\0
But my Unity3D Web App says : Exception: Unable to connect, as no valid crossdomain policy was found.
I don't know what I am missing. Unity uses by default port (843).
Where to put the crossdomain.xml
Any help is welcome !
CrossDomainPolicy.xml must be at the root of your application.
If you are using single Web Role just add CrossDomainPolicy.xml at the root of your application and set it up correctly as below:
Depends on how many "sites" sections you have in your role's ServiceDefinition.csdef , you will get that many \sitesroot\0 and \sitesroot\1 and CrossDomainPolicy.xml will be distributed to all depend on your role solution settings.
Once I discussed this in my following blog:
Silverlight front end calling to WCF Service, all in one Windows Azure Web Role Sample
You mentioned port 843, which sounds like it would need the Flash protocol, which is a TCP socket listener on port 843 that responds with the cross domain policy when it receives the text <policy-file-request/>. Do you need to be doing that? Does your app use sockets?
Avkash's answer is correct for where the XML file should go if you just need to serve it via port 80 from your web app, but if you need to do raw sockets, you'll need to be running something on the server that handles that.

What is the best way to restrict access to a development website?

I have a site i am working on that i would like to display only to a few others for now. Is there anything wrong with setting up windows user names and using windows auth to prompt the user before getting into the development site?
There are several ways, with varying degrees of security:
Don't put it on the internet - put it on a private network, and use a VPN to access it
Restrict access with HTTP authentication (as you suggest). The downside to this is it can interfere with the actual site, if you are using HTTP auth, or some other type of authentication as part of the application.
Restrict access based on remote IP. Just allow the IPs of users you want to be able to access it.
Use a custom hostname. Have it on a public IP, but don't publish the hostname. This means make an entry in your HOSTS file (or configure your own DNS server, if possible) so that "blah.mysite.com" goes to the site, but that is not available on the internet. Obviously you'd only make the site accessible when using that hostname (and not the IP).
That depends on what you mean by "best": for example, do you mean "easiest" or "most secure"?
The best way might be to have it on a private network, which you attach to via VPN.
I do this frequently. I use Hamachi to allow them to access my dev box so they can see whats going on. they have access to it when they want , and/or when I allow. When they are done I evict them from my Hamachi network and change the password.
Hamachi is a software VPN. Heres a link to Hamachi - AKA LogMeIn
Hamachi
They have a free version which works quite well.
Of course, there's nothing wrong with Windows auth. There are couple of (not too big) drawbacks, though:
your website auth scheme is different from the final product.
you are giving them more access to the box they really need.
you automatically reimaging the machine and redeploying the website is more complex, as you have to automate the windows account creation.
I would suggest two alternatives:
to do whatever auth you plan on doing in the final website and make sure all pager require auth
do a token cookie based auth - send them a link that sets a particular token in a cookie and in your website code add quick check for that token before you even go to the regular user auth
If you aren't married to IIS, and you need developers to be able to change the content, I would consider Apache + SSL + WebDav (aka Web Folders). This will allow you to offer a secure sandbox where developers can change and view the content without having user accounts on the server.
This setup requires some knowledge of Apache so it only makes sense if you are already using Apache or if you frequently need to provide outsiders access to your web server.
First useful link I found on the topic: http://pascal.thivent.name/2007/08/howto-setup-apache-224-webdav-under.html
Why don't you just set up an NTFS user and assign it to the website (and remove anonymous access)

Can you have virtual users using an SFTP server?

I've had a FTP server (Mac OS X, but not the server version) set up for a while where the users are virtual, i.e. they are not actual user accounts in the server's OS, but accounts handled by the FTP server software -- to the OS they all look like the ftp user account. I'd like to retire the FTP server software and go SFTP instead.
Is there a way to set up SFTP/SSH so that I can create virtual users and at the same time sandbox them?
The reason I want virtual users is because I add and remove accounts from time to time, and doing that with proper user accounts tend to get messy, and I don't know of a good way to sandbox them. There's always some files left and each user has their own user directory (with a lot of files only relevant if they would actually log on to the machine when sitting in front of it), which is quarantined when the account is removed, so you have to remove it by hand yourself, and so on.
The usual generic Unix answer to this is 'PAM'. If you want plain old OpenSSH SSHD to handle your SFTP, you need something plugged in to SSHD's PAM stack (/etc/pam.d/sshd) that does what you need and leaves out what you don't need. This might be a general-purpose directory server (probably LDAP) that maps all your virtual users to one home directory and gives them a restricted or scponly kind of shell.
If you want to look at FTP servers that can also do FTP-ssl (which is not the same as SFTP), good ftp servers like Pure-ftpd or vsftp will do that. FTP-ssl servers have simpler virtual user support.

If you're open to commercial products, VShell Server from Van Dyke Software is available on Unix/Linux/Windows, supports virtual users (multiple backends) with SSH and SFTP protocols:
VShell Server
JSCAPE SFTP Server is a commercial, cross-platform server that does what you want.

I know, sounds like I work for them, but I don't :)
There is sftpgo which supports virtual users and much more.
