Introduction ========== Scality provides as part as its product an NFS server and a SMB server on Linux (Ubuntu/RHEL/CentOS). To handle connection balancing and fail-over we have developed a piece of software which can either be run as a stand-alone process or used as library from an NFS / SMB server There's a few commands associated with the Virtual Server for getting status and performing management actions. It basically assigns IP aliases (aka Virtual IP's) to machines, and reshuffles these aliases when nodes appear, leave, fail... It's written in C and we’re currently focusing mostly on the fail-over usage of this Virtual Server. It also monitors NFS instances and react when an NFS server dies. There are different policies to associate an alias to a new customer (NFS or SMB client). We do need to extend the suite of automated tests we have for this software. This will include dealing with multiple (virtual) machines for the (NFS/SMB/...) servers and their Virtual Servers instances. We need to insure aliases move as expected from one machine to the other upon configuration changes (machine joining, leaving, process or communication failures). Hence this will include triggering such events and injecting failures, and checking the result is fine. For the admin part, we use salt to ease the management of the software on the set of machines. The tests produced must be based on pytest, to ease further integration with our internal framework. Details / Inputs ============ Scality will provide a test environment based on a set of virtual machines providing: - a Scality storage deployment already set up and ready to use (it's basically a set of 6 virtual machines with some storage capacity. This can be ignored from the test developer stand point) - A set of virtual machines where NFS/SMB servers will run, as well as the virtual server software. It will be up to the tests to configure and start these servers and the Virtual Server Daemon according to the tests scenarios. - A virtual machine where the PyTest will be run. - NFS/SMB clients will be run on the virtual machines used to provide Scality's Ring. The Scality Virtual Server relies on a set of 3 ZooKeeper instances. These ZooKeeper instances will be running on the virtual machines provided for the Scality RING. The existing tests scenarios will be provided as examples. Goals ===== Milestone 1) Implement one additional pytest scenario: - Provision the virtual IP addresses in ZooKeeper using the Virtual Server management tool. - Install and start NFS servers and their companions Virtual Servers. - Start one or more NFS client on some of the NFS servers, with some real traffic. - Force reboot (not shutdown) of one of the machines hosting one of the NFS servers. - Check that the status of the VIP's among surviving NFS servers is OK - Check that NFS requests are still served correctly from the failed-over NFS server. Milestone 2) Take the existing scenarios involving the NFS servers and adapt them to SMB. - A working configuration with SMB servers will be provided, to avoid wasting time on Scality SMB servers configuration. Acceptance criteria =============== Deliver the pytest files implementing the above scenarios. Demonstrate a successful run of these tests within the provided environments. Code provided will be reviewed. Requested modifications resulting from the review must be applied to provided code. Possible extensions ================ Further missions / jobs will be possibly defined as a result of this mission. Skills ==== Python, Salt, Tests, NFS, SMB, Network administration, Virtual Machines

Hello, We have a Network compliance scan scheduled in a day . The scan has been performed twice and we failed to comply. I have the copy of compliance scan done before and there are a few items we fail on. I am looking for some on who can help me fix these issues quickly. The Scan is done externally by a third party firm. We have Dell Sonicwall Firewall. It is very urgent and needs to be done today. Thanks Nick

Hi, We had problems with one computer, so I decided to install Windows 10 again new. No all the network settings are gone :-( I've no time to spend hours for that, so I search someone who can do this for me. Access information for the server and the NAS are prepared, you will have access by teamviewer. I think it a twenty minute job for a pro.

I need your help. I've followed the instructions found here: But I hit a wall when trying to create the OPVN file. It failed, and I don't have time to debug. I need this setup before end of day Friday. I'm also trying to setup a Samba share on this Raspberry pi -- perhaps you could help me with that too. I could do it myself, but I'm just too busy these next two days to go and find the how-to docs and walk through it. Hopefully you have experience with these two tasks and it'll take you less than an hour to get them both up and running. I'd probably just want to watch over your shoulder while you log in to the Raspberry Pi -- perhaps you could TeamViewer into my machine and from there SSH into the Raspberry Pi. I've got Verizon FIOS ( and am using it as my gateway/router with the default firmware installed. I also have additional Wi-Fi access points connected via ethernet to the gateway/router adding additional wireless coverage as well as wired ports at various points around the home. I'm also planning on accessing the DLNA server running on the Raspberry Pi from whatever device I'm using that will be connected to the Raspberry Pi via OpenVPN. So, as part of the work I'd need you to just help make sure that port forwarding is working properly through the gateway/router. Using my smartphone, I'll install the OPVN file and attempt to connect to the Pi and stream from the DLNA server. Testing the Samba share should be easy too. Thanks.

Looking for an experienced developer to write a query in MS SQL Server. The query will be executed via an ODBC connection in Excel. This is a single project, however if results are good, other MS SQL Server / ODBC projects may follow. Estimated time to complete this one project is +/- 5 hours. The query is relatively simple and straight forward. I need the query to list the orders within a defined date range. I can provide table and field names to expedite your work. The goal is to list the employee's name who entered the order. The query will most likely be for a 1 week date range and list approximately 50 - 100 records. You will communicate with me via email and Skype. You will remote into our system via a VPN connection in order to access our database. You must: 1. Have good written and spoken English communication skills. It is not necessary to be a native speaker. I just have to be able to understand you. 2. Be responsive to my communication and know when to ask questions. 3. Be emotionally mature and welcome and appreciate honest feedback without being upset. 4. Be reliable. Don't commit to tasks and deadlines you can't complete. 5. Be pro-active. Suggest a better process in order to make tasks more efficient. All suggestions must receive my approval prior to being implemented. 6. Be a finisher. 95% complete isn't finished. Please reply and tell me how you can help. Thank You

We have an Xfinity account currently where we login via the comcast website to gain access to the website. An example is, I have my laptop, and where there is an Xfinity account, I can click on the ssid "xfinitywifi" and my laptop connects. I would like to be able to purchase a router (you tell me which), so that I can connect to this router, along with 3 other computers that I have, as well as a wireless printer. It sounds simple, but the reality is that we need to add a user name and password to get access to surfing. I would like to use the router that we purchase so that I can use one of the laptops to share data, and share printers.

Background : a normal proxy requires the computer running the proxy to have it's ports open and forwarded. I need proxy that does not need the Remote Computer to perform Port forwarding and instead it will be my computer which will need the ports forwarded and open, hence why its called a reverse proxy. you can read more about reverse proxies here Functionally: the program will be divided by two : Server side & Client side. 1.Server side: the server side will run on my computer and will include a listener option to listen on incoming connections. it will have 2 options : Start, Build. 1.2)Start - the start option will let me configure a port number, and start a listener on that port 1.3)Build- the build option will configure the client side (proxy.exe). it will have the option to input my public IP ( for the listener to listen on) and port. after pressing ' build' it will produce an FUD executing file (proxy.exe) to the Proxy folder. 2)Client Side : the client Side is basically the executing file that came from the server builder - its the proxy.exe It needs to run on any windows system, open a connection to my public IP, and connect to the server which is listening on that IP:Port, according to the configurations on 1.3 in the end, i need to be able to surf the web from an other Public IP.

I have a dedicated server - 500GB/ 8GB RAM I can also get a local server built if needed or use a laptop. I want to create virtual desktops that I can remote login into via RDP or VNC. There should be an easy way to manage the VMs and to change the MAC addresses of each VM. When disconnecting, the VM should suspend or disconnect. There should be over 500 VM images on the server. Best solution would to probably use a linked clone or something similar to that. Regarding IPs, I need to be able to remote login via a dedicated ip or a solution like Then I need the VM to use a connected mobile hotspot system that I physically have. I need a way to for the server to access my local mobile hotspot internet as a proxy. Please let me know what solution you propose. ok
