• Deny to administrators to change network configuration settings

  - by moronrats

  I need to provide admin rights to every user but the users should not able to change network configuration settings. For this I have enabled following policies in User Configuration\Administrative Templates\Network\Network connections Enable Windows 2000 network connection settings for administrators Prohibit access to properties of a LAN connection Prohibit access to properties of components a LAN connection Users (that exist in administrators) still can change the LAN properties. Are there any other solutions?

• JBoss: Adding a New Binding for a New Service

  - by mlaverd

  Hello, Warning: I'm a J2EE newbie. I have a server application that receives TLS connections containing Protocol Buffers messages. I'd like to port it to J2EE to take advantage of all its powerful features. Is there a way to add a binding that would have TLS enabled and would speak to my piece of code for interpreting and handling the request's data? If so, how? Thanks in advance!

• Blank graph for some munin plugins

  - by jack

  I have a munin-master and munin-node installed on same server (Ubuntu 9.10 server). Most pre-installed plugins work well but the following plugins are with blank graph: Memcached bytes used Memcached connections Memcached cache hits and misses Memcached cached items Memcached requests Memcached network traffic MySQL Queries Cache Size I run the following 3 script in terminal and results were ok. /etc/munin/plugins/memcached_bytes /etc/munin/plugins/memcached_counters /etc/munin/plugins/memcached_rates But when I tried the command below after "telnet localhost 4949" fetch memcached_bytes # Unknown service etch memcached_bytes_ # timeout pid 28009 - killing...done Does anyone know the reason?

• Are FC and SAS DAS devices standard enough?

  - by user222182

  Before I ask my questions, here is some background info that may or may not be useful: For the first time I find myself needing a DAS solution. My priority is data through-put in a single direction. I can write large blocks, and I don't need to read at the same time. The server (the data producing device) is not really a typical server, its a very powerful single board computer. As such I have limited options when it comes to the add-in cards I can install since it must use the fairly uncommon interface, XMC. Currently I believe I am limited PCIex8 gen 1 which means that the likely bottle neck for me will be this 16gbps connection. XMC Boards I have found so far offer the following connections: a) Dual 10GBE ethernet controller, total throughput 20gbps b) Dual Quad SAS 2.0 Connectors (SFF-8XXX) HBA (no raid), total throughput 48 gbps c) Dual FC 8gb HBA (no raid), total throughput 16gbps My questions for you guys are: 1) Are SAS and/or FC, and by extension their HBAs, standard enough that I could purchase a Dell or Aberdeen storage server with a raid controller that has external SAS or FC ports and expect that I can connect it to my SAS or FC HBA, be presented with a single volume (if I so configured the storage server), all without having to check for HBA compatibility? 2) On a device like a Dell PowerVault (either DAS or NAS) is there an OS on it to concern myself with, or is it meant to be remotely managed? Is there a local interface in case I cant remotely manage it (i.e. if my single board computer uses an OS not supported by Dell OpenManage). Would this be true of nearly any device which calls itself a DAS? 3) If I purchase some sort of Supermicro storage chassis, installed a raid controller with external connections, is there a nice lightweight OS I can run just for management of the controller? Would I even need an OS since the raid card would be configured pre-boot anyway? 4) It is much easier to buy XMC based 10gigabit ethernet cards (generally dual port). In what ways would I be getting into trouble by using iSCSI as a DAS are direct cabling with SFP+ cables? Thanks in advance

• How can I easily test connectivity to external sources with WinHTTP?

  - by Mike B

  I've got an server application that uses Winhttp to fetch information from an external source. Occasionally, I'll need to troubleshoot connectivity issues and I'd like an easy way to test connections through winHTTP (on the off-chance that there's something that is specifically impeding winHTTP and not other unrelated connectivity commands like telnet). Does IE use WinHTTP? If not, are there any tools (preferably already integrated into Windows) that I can use? Occasionally I'll use IE but I'm not sure if that's quite the same.

• Fortigate 80C multi wan

  - by emamdouh

  I've Fortigate 80c and two internet lines from two separate ISPs. I'm trying to distribute sessions between both internet lines following http://docs-legacy.fortinet.com/cb/html/index.html#page/FOS_Cookbook/Install_advanced/routing_ecmp_basic.html , but it seems connections go through just one of two internet lines. I have "wan1 as it's configured first, and I could edit static route table to be wan2 instead of wan1", but not both of internet lines I have. Any ideas why this happens? Thanks in advance

• Multiple IPs on single server - Specify which is used to connect (MS server 2008 / DNS)

  - by runboy

  I have a Windows 2008 server with multiple IPs that is acting as DNS server. I have set the DNS server up to only accept connections on a single of these IPs. The DNS is serving as secondary DNS and when it connects to the primary DNS server it is not connecting with this particular IP address, but one of the other IPs. Is there a way in which I can make sure the server connects using the correct IP?

• What other protocols must not be fire-walled for FTP to work?

  - by Chris

  my Netgear router randomly reset itself the other day loosing all of my config settings: DSL details, Firewall rules, the lot! So I set about restoring all of the details manually, but when it came to configuring the firewall I wanted improve the security by explicitly setting 'deny' rules for everything that I figured is 'non-essential', and (although not necessary) whilst I was at it I set explicit 'allow' for the 'essential' protocols. I'll admit now I didn't really know what I was doing and everything was just 'my best guess', but I enabled only DNS, HTTP, HTTPS, FTP, SFTP, TFTP with everything else blocked. This did not work for me as I could not access 99% of web sites (although strangely Google worked!), so I played around a bit more and found that (oddly) if I disabled just the explicit 'allow' rules then everything worked fine, for browsing anyway. Today I came to work on some web-sites via FTP and just could not get a consistent connection, it kept dropping out after a few files or being blocked by the server or simply not connecting. It would authenticate okay but then stop when retrieving the initial directory listing! e.g.: Status: Delaying connection for 1 second due to previously failed connection attempt... Status: Resolving address of ftp.domain.co.uk Status: Resolving address of ftp.domain.co.uk Status: Connecting to 123.123.123.123:21... Status: Connecting to 123.123.123.123:21... Status: Connection established, waiting for welcome message... Status: Connection established, waiting for welcome message... Response: 421 Too many connections (8) from this IP Error: Could not connect to server Status: Delaying connection for 5 seconds due to previously failed connection attempt... Response: 421 Too many connections (8) from this IP Error: Could not connect to server Status: Delaying connection for 5 seconds due to previously failed connection attempt... I've checked and re-checked the FTP settings (they worked before anyway), I have Googled the I.T. out of the various protocols that I have blocked in the fire-wall but none seem essential to FTP (other than FTP/SFTP etc. which I have passively enabled). I'm (clearly) no server engineer, or protocols / fire-wall expert so I was hoping that some one could maybe shed some light on why my FTP is failing. I've been wondering if I ought to be allowing BGP, BOOTP and/or IDENT (or any others)? What other protocols are required for FTP? Thanks in advance!

• Why won't vyatta allow SMTP through my firewall?

  - by Solignis

  I am setting up a vyatta router on VMware ESXi, But I see to have hit a major snag, I could not get my firewall and NAT to work correctly. I am not sure what was wrong with NAT but it "seems" to be working now. But the firewall is not allowing traffic from my WAN interface (eth0) to my LAN (eth1). I can confirm its the firewall because I disabled all firewall rules and everything worked with just NAT. If put the firewalls (WAN and LAN) back in place nothing can get through to port 25. I am not really sure what the issue could be I am using pretty basic firewall rules, I wrote the rules while looking at the vyatta docs so unless there is something odd with the documentation they "should" be working. Here is my NAT rules so far; vyatta@gateway# show service nat rule 20 { description "Zimbra SNAT #1" outbound-interface eth0 outside-address { address 74.XXX.XXX.XXX } source { address 10.0.0.17 } type source } rule 21 { description "Zimbra SMTP #1" destination { address 74.XXX.XXX.XXX port 25 } inbound-interface eth0 inside-address { address 10.0.0.17 } protocol tcp type destination } rule 100 { description "Default LAN -> WAN" outbound-interface eth0 outside-address { address 74.XXX.XXX.XXX } source { address 10.0.0.0/24 } type source } Then here is my firewall rules, this is where I believe the problem is. vyatta@gateway# show firewall all-ping enable broadcast-ping disable conntrack-expect-table-size 4096 conntrack-hash-size 4096 conntrack-table-size 32768 conntrack-tcp-loose enable ipv6-receive-redirects disable ipv6-src-route disable ip-src-route disable log-martians enable name LAN_in { rule 100 { action accept description "Default LAN -> any" protocol all source { address 10.0.0.0/24 } } } name LAN_out { } name LOCAL { rule 100 { action accept state { established enable } } } name WAN_in { rule 20 { action accept description "Allow SMTP connections to MX01" destination { address 74.XXX.XXX.XXX port 25 } protocol tcp } rule 100 { action accept description "Allow established connections back through" state { established enable } } } name WAN_out { } receive-redirects disable send-redirects enable source-validation disable syn-cookies enable SIDENOTE To test for open ports I have using this website, http://www.yougetsignal.com/tools/open-ports/, it showed port 25 as open without the firewall rules and closed with the firewall rules. UPDATE Just to see if the firewall was working properly I made a rule to block SSH from the WAN interface. When I checked for port 22 on my primary WAN address it said it was still open even though I outright blocked the port. Here is the rule I used; rule 21 { action reject destination { address 74.219.80.163 port 22 } protocol tcp } So now I am convinced either I am doing something wrong or the firewall is not working like it should.

• monitor internet bandwidth

  - by enriquev

  Hello, I'm looking for a windows tool that can tell me who is using bandwith. As of now I've setup so that the switch where all pcs are connected, mirrors the router's traffic to my pc, meaning that from my NIC I am able to see all outgoing and incoming internet connections. This works, I have used NIMAS (http://www.vmware.com/appliances/directory/200) and I am able to see internet traffic. Now what I am looking for is something even more simple, where I can see what computers are using what banwidth, live.

• IBM Websphere MQ Server alternatives

  Are there any alternatives to IBM Websphere MQ Server for Windows? We need to access a remote Queue Manager that doesn't support client connections (only Queue Manager to Queue Manager). I've noticed that there are some BizTalk Host Integration adapters but they only seem to behave as clients (one transactional, the other non-transactional).

• IIS/ASP.NET performance incident - Perfmon Current Annonymous Users going through roof but Requests/sec low

  - by Laurence

  Setup: ASP.NET 4.0 website on IIS 6.0 on Win 2003 64 bit, 8xCPUs, 16GB memory, separate SQL 2005 DB server. Had a serious slowdown today with any otherwise fairly well performing ASP.NET site. For a period of a couple of hours all page requests were taking a very long time to be served - e.g. 30-60s compared to usual 2s. The w3wp.exe's CPU and memory usage on the webserver was not much higher than normal. The application pool was not in the middle of recycling (and it hadn't recycled for several hours). Bottlenecks in the database were ruled out - no blocks occurring and query results were being returned quickly. I couldn't make any sense of it and set up the following Perfmon counters: Current Anonymous Users (for site in question) Get requests/sec (ditto) Requests/sec for the ASP.NET application running the site Get requests/sec was averaging 100-150. Requests/sec for ASP.NET was averaging 5-10. However Current Anonymous Users was around 200. And then as I was watching, the Current Anonymous Users began to climb steeply going up to about 500 within a few minutes. All this time Get requests/sec & Requests/sec for ASP.NET was if anything going down. I did a whole load of things (in a panic!) to try to get the site working, like shutting it down, recycling the app pool, and adding another worker process to the pool. I also extended the expiration time for content (in IIS under HTTP Headers) in an attempt to lower the number of requests for static files (there are a lot of images on the site). The site is now back to normal, and the counters are fairly steady and reading (added Current Connections counter): Current Anonymous Users : average 30 Get requests/sec : average 100 Requests/sec for ASP.NET : 5 Current Connections : average 300 I have also observed an inverse relationship between Get requests/sec & Current Anonymous Users. Usually both are fairly steady but there will be short periods when Get requests/sec will go down dramatically and Current Anonymous Users will go up in a perfect mirror image. Then they will flip back to their usual levels. So, my questions are: Thinking of the original performance issue - if w3wp.exe CPU, memory usage were normal and there was no DB bottleneck, what could explain page requests taking 20 times longer to be served than usual? What other counters should I be looking at if this happens again? What explains the inverse relationship between Get requests/sec & Current Anonymous Users? What could explain Current Anonymous Users going from 200 to 500 within a few minutes? Many thanks for any insight into this.

• What can I use to monitor which IP address w/name resolution is connected to each PID?

  - by supercheetah

  This would be for under Linux particularly. Is there a tool out there, or a script that I could use to monitor IP connections--with name resolution--and, see which process they're connected to? Right now I'm using this: watch -d netstat -peeW --numeric-hosts --inet But that doesn't give me host resolution. I was thinking of writing up a script with sed or something, but that seemed like more work than it needed to be.

I need to do this on my iphone as I can no longer access via ssh or with the iphone cable. One of the files to edit is a ssh config file which is what is not allowing ssh connections. Any ideas on apps or other methods that I could use.

• Internet Working, Browsing Not.

  - by jeffreypriebe

  I have a very odd problem that I can't resolve. I am connected to the internet, but my browsing doesn't work. I don't mean a web browser - I mean browsing. Firefox, Chrome, Curl all fail to successfully connect to an HTTP address. However existing connections, e.g. to mail in Outlook (Exchange Server and also IMAP server) continue to work. Also, the internet is on, I can confirm both from my machine (other ports / connections) as well as from any other computer connected to the same network. Additionally, it appears to be HTTP, not simple a port issue as HTTP over port 8443 (Tortoise SVN if you must know - running over HTTP not over SVN) also fails. I am using Windows Vista SP2 (build 6002). It seems to "creep up" in that after running the computer for a few hours it will fail. (No found way to systematically reproduce the problem.) Additionally, it seems to be more prone on days where the internet connection is flaky already (not sure why the internet is flaky, just is, lot's of failed browsing requests and have to retry/reload often). What I have tried (when the problem arises) - none have yielded any resolution: Resetting the network connection (dis-connect, re-connect) Disable/re-enable the network adapter Double-checked the ip settings Double-checked the HOSTS file. Note: DNS continues to work (both new and cached responses to DNS queries). (Thanks for the suggestion Daniel and antenore.) Checked the routing tables (ip4 only as ipv6 is beyond my understanding) resetting all involved hardware (routers and modems) Close and reopen browsers Looked for malware interference: Run HijackThis Looked for suspicious processes using SysInternals procexp. Looked for explorer hijacks, lsa provider interference, winsock provider interference using SysInternals Autoruns. Run a complete anti-virus scan. Reviewed the output of a netstat -onab to see if there were stuck ports open or unusual processes running somewhere The only thing that works is to do a full reboot. That works 100% of the time to restore browsing. What else can I try to nail down the problem?

• Multihomed Windows server and DNS resolution

  - by mpkilroy

  I have a Windows 2008 server with two IP addresses assigned to a single NIC. The DNS settings are setup to register the connections's addresses on the DNS server. nslookup shows both IP addresses for the server name. How is name resolution done in this case, i.e. which IP address does the DNS server return for a host lookup? Or does it return both, and the client selects one of the addresses?
