• How to install Ubuntu One server software or alternative for personal use?

  - by lastpak

  I have a Debian based box in my house that runs as a webserver, and a 4GB bootable usb-stick with Ubuntu. I need to store stuff on a server and Ubuntu One seems an ok way to go but I find that 2GB is not sufficient. I can most likely solve that when I install this server software. Where can I find it - there is no ubuntu-one-server package or similar in the Software Centre. How can I install the Ubuntu One server software or an alternative?

• Exchange 2010 DAG Automatic Failover Testing/Issue. Not always automatically failing over to health

  - by Richard

  Ok I've got 2 exchange 2010 servers that run client access/hub transport/mailbox roles and one exchange 2010 server running just client access/hub transport roles and acts as my bridgehead. The two mailbox servers are running one database setup in a DAG. Server A shows the DB Mounted and Server B shows Healthy. If I reboot Server A via windows GUI Server B switches from healthy to mounted and I see hardly any interruption in service using Outlook 2007. Server A shows "Service down", then "Failed" then "Healthy" and leaves the DB mounted on Server B. This is how it should work, so far so good. Now if I test Server A being shut down cold, or unplugging both nics from network to simulate failure, Server B switches from Healthy to Mounted and server A switches to "Service Down" but my outlook client never connects to the DB mounted on server B! I can connect to server C (client access/hub transport) and get to my email and even send new email out, but incoming email doesn't deliver until Server A is brought back online and it's DB goes back to Healthy status. So I don't understand why it auto fail-overs when I reboot the server with the mounted DB copy, causing very little outlook 2007 hiccup if any. But when I shutdown or DC the mounted DB server it DOES mount the healthy copy but outlook 2007 clients can't connect.. I hope the picture I'm trying to paint makes some sense, it's driving me a little batty. Any help would be appreciated!

• How can I install Message Queuing on Windows Server 2003?

• ClearOS - how to avoid getting stuck at a fsck message at boot?

  - by Scott Szretter

  I have had this happen a couple times - I have a ClearOS Enterprise 5.2 box, and due to a power outage or similar, it ends up showing an error at boot and saying that fsck needs to be run (I think it said with (or without?) the -a parameter). The problem is, I need this box to be headless, at a remote location (miles away)! SO, I need to come up with a solution on how to either have it automatically repair itself, without someone to be present with a monitor and keyboard. Another possibility is to simply avoid the issue all together - maybe there is something that can be changed so it's very unlikely to happen (I am unable to avoid the power outage of course - at least not practically). Finally, maybe it can be boot off a read only media (cd) or file system or similar? At least the base OS, so that it would always at least boot with enough configuration that might allow remote access, or basic connectivity?

• Memcached server: Is it a good practice to point two server urls to the same server?

  - by Niro

  I have a system where there are connections to a memcache server from several different files and servers. I would like to stay with one server but keep the option of increasing the number of memcache servers (for periods of of high traffic). My idea is to tell memcache there are two servers, while the two urls will point (by DNS) to a single server. In the future if I want I can add a server and change DNS without changing the code in many places. Is this a good practice? Is there a performance cost to the fact that there are two server connections but they both point to the same server? Any other idea how to achive instant expeandability of memcache capacity without need to change the code and deploy ?

• Security considerations on Importing Bulk Data by Using BULK INSERT or OPENROWSET(BULK...)

  - by Ice

  I do not understand the following article profound. http://msdn.microsoft.com/en-us/library/ms175915(SQL.90).aspx "In contrast, if a SQL Server user logs on by using Windows Authentication, the user can read only those files that can be accessed by the user account, regardless of the security profile of the SQL Server process." What if i define a SQL-Agent Job to perform this bulk-Insert; Is it the OWNER of the Job who gives the security-context?

• Is DHCP required on a Win2003 secondary DNS server?

  - by Mark

  We have a secondary DNS server and we've been noticing that the DNS.exe process is getting rather large. (Like, rebooting the server large) I read something somewhere that 2k3 has two relevant memory leak issues, one is the DNS (supposedly fixed in 2007), and another for DHCP. DHCP is running on this server, but I don't see why. Hence my question. Is the DHCP service required for (secondary) DNS to function? Server has: 24 cores (X5650), 8GB RAM

• DHCP: server behavior in a two server situation

  - by lang2

  This is a question w.r.t server behavior in the DHCP standard. I've read the RFC and it's still not clear to me. Situation is this: There are two DHCP servers on a network. My client initially get IP address from server A. At some stage, server A goes down. My poor client is sending REQUEST in RENEW and then REBIND state, with no response whatsoever. My questions is: in this situation, should server B response to the REQUEST in REBIND state, e.g. DHCPNAK? Thanks, lang2

• IIS Seems to Forward Domain/IP to Domain Controller

  - by asinc

  We have a server (Server 1) with Win 2008 that is accessible by RDP and also is set as the primary DNS IP for a domain (example.com). This server is on the same network as an SBS 2008 server (Server 2) which is the domain controller and internal Dns server. Web requests going to example.com with IP of Server 1 are being passed to Server 2 and served up by IIS from Server 2. What causes this to happen? Is there a safe way to have Server 1 IIS handle the web requests which was our expected outcome? Example: DNS entry on ISP: example.com = 111.111.111.111 Server 1 = 111.111.111.111 Server 2 = 111.111.111.112 Web user goes to example.com in browser, and the page is actually returned from 111.111.111.112?

• What anti-virus & firewall (with IDS) should I use for a windows server machine?

  - by Eran Betzalel

  I want one product to cover for Anti-virus & Firewall purposes. The product should also be lightweight and of course designed for windows server. Any suggestions? Note: I don't need an enterprise solution for the clients - only for the server. BTW, I currently using Symantec SEP, but it's too heavy (during weekly scans) for the server to handle and is not designed for server purposes.

• pfsense CARP - wan failure on firewall

  - by eldblz

  I have recently configured 2 firewall (on 2 DELL PowerEdge R210II with ESXI 5.1) with pfsense. We have several LANs and 2 WANs. Everything is running fine but i have a strange behavior: i can access internet from alla LANs but not from the firewall (itself). For example the firewall cannot retrive package information or if i setup a gatway monitor ip (like google 8.8.8.8 ) this fails. These are the screenshots of firewall configuration: http://imgur.com/a/LNuMz#0 ATM i kept firewall rules to minimum to avoid problem or conflicts. Any ideas how to solve the problem? Thank you in advance.

• como se que esta funcionando AWE?

  - by adan851018

  Tengo un servidor con 8GB de RAM de 32 bits, instale windows server 2003 enterprise y sql server 2005 enterprise, el Sistema Operativo reconoce los 8GB, pero el Sql Server solo usaba 1.6 GB de memoria, entonces agregue al boot.ini el parametro /PAE y en Sql Server le habilite AWE de 1GB a 5GB, despues de reiniciar el servidor el Sistema que usa la BD estaba mas rapido mejoro bastante, pero en memoria el Sql Server solo usa 100 MB, veo la cantidad de memoria usada en el Administrador de Tareas de Windows, y no se si esta funcionando AWE o que sucedio? Rough translation: I have a server with 8GB of RAM 32-bit, install windows server 2003 enterprise and sql server 2005 enterprise, the operating system recognizes the 8GB, but the SQL Server only using 1.6 GB of memory, then add to boot.ini the parameter / PAE and will enable AWE Sql Server 1GB to 5GB, after rebooting the server using the database system was faster, the better lot, but in memory the SQL Server only uses 100 MB, I see the amount of memory used in Manager Windows Tasks, and not if AWE is running or what happened?

• How to prevent the "other user" from appearing on the logon screen of a server?

  - by user114106

  When I want to log into a server console (Server 2008 R2), I click Ctrl+Alt+Del and get "Other User" that I need to click before I get the log in box to add my credentials. This wouldnt be so bad, but I want to use this server as a Citrix server and so far every user that tries to connect has to click other user before they can add thier own credentials.. Has anyone got any ideas on ewhat I can do to get this to go straight to the username and password without the extra click?

• How do I remotely enable the firewall on Server 2008 to exclude specific IP addresses?

  - by Guy

  Previously I was working with Server 2003 and managed to lock myself out of the server (I was accessing it remotely) by enabling the firewall. I want to remotely enable the firewall on Server 2008 without locking myself out of the server (access via RDP) and then selectively add IP addresses to the firewall to exclude. i.e. block specific IP addresses. Are there any step by step instructions on how to safely do this?

  Does it work to have like an MySQL (or any other relational database) on the GFS (with DRBD) and have multiple nodes reading and writing to it? Is that the "best" way of providing a HA database/application setup if so? Is RHEL (cluster suite) a good way to set up this? (or centos)

• How can I preserve share paths when moving a share to a new server?

  - by realitnzsam

  Hi guys, I have 2 servers and I just moved most of the shares from server1 (SBS 2003 server) to server2 (Server 2003 Standard). However, in sharepoint there are a lot of links that refer to the old server by name, ie, \\server1\accounts. How can I have the shares physically on the new (larger) server, while preserving these links and having them still work. Cheers, Sam

• What happens if an OpenStack cloud controller dies?

  - by magu

  I've been reading up on OpenStack and how we can re-create an EC2/S3-style cloud for our internal development and I'm having a hard time finding information on how the OpenStack cloud controller provides redundancy of the cloud management services. I know I can setup multiple Swift and Nova nodes, but not a single document/article/howto/wiki contains information on: a) what happens if the cloud controller node dies; and b) how to setup redundant cloud controllers. It seems to me that, although it is massively scalable, there is a big single-point-of-failure built into OpenStack. Can anyone with more experience on OpenStack please shed some light as to how it all works in regards to high-availability?

• How to setup dhcp3-server to advertise the DNS server the server itself has got from DHCP?

  - by Ivan

  The Ubuntu 10.04 server has eth0 Internet interface configured by means of an ISP's DHCP. At the same time the server has static eth0 LAN interface to which it provides masquerading (NAT) and LAN-internal DHCP service (dhcp3-server). As far as I've understood the manual, I had to hardcode DNS servers to advertise through LAN DHCP with option domain-name-servers in dhcpd.conf. But what if the ISP changes his DNS server IP silently (we use a SOHO-class ISP, so this won't surprise me much)? Can I configure dhcpd to advertise the DNS server the server uses itself, the one gotten by its DHCP client mechanism?
