• Why can I not get a WDS-originated PXE boot to progress past the first file download?

  - by Jeff Shattock

  I'm trying to work out an automated Windows install process, and thought I'd give WDS a look. After some promising initial progress, I seem to have hit a wall. I imported the boot and install WIMs, and created the capture WIM successfully. However, whenever I try to PXE boot the reference machine against the WDS server, it kinda craps out. It finds the server and downloads WDSNBP.COM successfully, and then gives the message "TFTP download failed." According to WireShark, the only communication between the WDS box and the client box is the successful TFTP request and download of boot\x86\WDSNBP.COM. No further requests are sent. The WDS log on the server shows the same thing, one successful download and no more activity. I've tried every combination of the following, with exactly zero change in behaviour: Win Server 2008R2 vs 2012 vs 2012R2 WDS virtualized on KVM, ESXi, VirtualBox, VMWare Workstation Client virtualized on KVM, ESXi, VirtualBox, VMWare Workstation Every network adaptor type offered by the virtualization platforms. "Actual" network vs isolated, virtual network. MS DHCP server vs Linux isc-dhcp-server Joined to a domain vs Stand-alone I tried changing the boot filename in DHCP to pxeboot.com instead, and it has no problem downloading that file instead, but it then crabs about Boot\BCD being corrupted. Also, with 2012, it doesnt appear that WDSNBP.com does the architecture detection, or at least does'nt report that it did. 2008 reports that it found x64, and then errors. I find myself out of things to check, and I dont see anything immediately wrong. Where do I go from here? WDS server is at 192.168.1.50, DHCP/DNS at 192.168.1.7. Console of the client computer after the boot: MAC: 52:54:00:28:94:0E UUID: blah blah Searching for server (DHCP)..... Me: 192.168.1.155, DHCP: 192.168.1.7, Gateway 192.168.1.1 Loading 192.168.1.50:boot\x86\wdsnbp.com ...(PXE).................done Downloaded WDSNCP...

• How to allow local LAN access while connected to Cisco VPN?

  - by Ian Boyd

  How can I maintain local LAN access while connected to Cisco VPN? When connecting using Cisco VPN, the server has to ability to instruct the client to prevent local LAN access. Assuming this server-side option cannot be turned off, how can allow local LAN access while connected with a Cisco VPN client? I used to think it was simply a matter of routes being added that capture LAN traffic with a higher metric, for example: Network Destination Netmask Gateway Interface Metric 10.0.0.0 255.255.0.0 10.0.0.3 10.0.0.3 20 <--Local LAN 10.0.0.0 255.255.0.0 192.168.199.1 192.168.199.12 1 <--VPN Link And trying to delete the 10.0.x.x -> 192.168.199.12 route don't have any effect: >route delete 10.0.0.0 >route delete 10.0.0.0 mask 255.255.0.0 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 192.168.199.12 >route delete 10.0.0.0 mask 255.255.0.0 192.168.199.1 if 0x3 And while it still might simply be a routing issue, attempts to add or delete routes fail. At what level is Cisco VPN client driver doing what in the networking stack that takes overrides a local administrator's ability to administer their machine? The Cisco VPN client cannot be employing magic. It's still software running on my computer. What mechanism is it using to interfere with my machine's network? What happens when an IP/ICMP packet arrives on the network? Where in the networking stack is the packet getting eaten? See also No internet connection with Cisco VPN Cisco VPN Client interrupts connectivity to my LDAP server Cisco VPN stops Windows 7 Browsing How can I prohibit the creation of a route in Windows XP upon connection to Cisco VPN? Rerouting local LAN and Internet traffic when in VPN VPN Client "Allow local LAN Access" Allow Local LAN Access for VPN Clients on the VPN 3000 Concentrator Configuration Example LAN access gone when I connect to VPN Windows XP Documentation: Route Edit: Things I've not yet tried: >route delete 10.0.* Update: Since Cisco has abandoned their old client, in favor of AnyConnect (HTTP SSL based VPN), this question, unsolved, can be left as a relic of history. Going forward, we can try to solve the same problem with their new client.

• MySQL is running VERY slow

  - by user1032531

  I have two servers: a VPS and a laptop. I recently re-built both of them, and MySQL is running about 20 times slower on the laptop. Both servers used to run CentOS 5.8 and I think MySQL 5.1, and the laptop used to do great so I do not think it is the hardware. For the VPS, my provider installed CentOS 6.4, and then I installed MySQL 5.1.69 using yum with the CentOS repo. For the laptop, I installed CentOS 6.4 basic server and then installed MySQL 5.1.69 using yum with the CentOS repo. my.cnf for both servers are identical, and I have shown below. For both servers, I've also included below the output from SHOW VARIABLES; as well as output from sysbench, file system information, and cpu information. I have tried adding skip-name-resolve, but it didn't help. The matrix below shows the SHOW VARIABLES output from both servers which is different. Again, MySQL was installed the same way, so I do not know why it is different, but it is and I think this might be why the laptop is executing MySQL so slowly. Why is the laptop running MySQL slowly, and how do I fix it?

• Advantage Database Server: slow stored procedure performance.

  - by ie

  I have a question about a performance of stored procedures in the ADS. I created a simple database with the following structure: CREATE TABLE MainTable ( Id INTEGER PRIMARY KEY, Name VARCHAR(50), Value INTEGER ); CREATE UNIQUE INDEX MainTableName_UIX ON MainTable ( Name ); CREATE TABLE SubTable ( Id INTEGER PRIMARY KEY, MainId INTEGER, Name VARCHAR(50), Value INTEGER ); CREATE INDEX SubTableMainId_UIX ON SubTable ( MainId ); CREATE UNIQUE INDEX SubTableName_UIX ON SubTable ( Name ); CREATE PROCEDURE CreateItems ( MainName VARCHAR ( 20 ), SubName VARCHAR ( 20 ), MainValue INTEGER, SubValue INTEGER, MainId INTEGER OUTPUT, SubId INTEGER OUTPUT ) BEGIN DECLARE @MainName VARCHAR ( 20 ); DECLARE @SubName VARCHAR ( 20 ); DECLARE @MainValue INTEGER; DECLARE @SubValue INTEGER; DECLARE @MainId INTEGER; DECLARE @SubId INTEGER; @MainName = (SELECT MainName FROM __input); @SubName = (SELECT SubName FROM __input); @MainValue = (SELECT MainValue FROM __input); @SubValue = (SELECT SubValue FROM __input); @MainId = (SELECT MAX(Id)+1 FROM MainTable); @SubId = (SELECT MAX(Id)+1 FROM SubTable ); INSERT INTO MainTable (Id, Name, Value) VALUES (@MainId, @MainName, @MainValue); INSERT INTO SubTable (Id, Name, MainId, Value) VALUES (@SubId, @SubName, @MainId, @SubValue); INSERT INTO __output SELECT @MainId, @SubId FROM system.iota; END; CREATE PROCEDURE UpdateItems ( MainName VARCHAR ( 20 ), MainValue INTEGER, SubValue INTEGER ) BEGIN DECLARE @MainName VARCHAR ( 20 ); DECLARE @MainValue INTEGER; DECLARE @SubValue INTEGER; DECLARE @MainId INTEGER; @MainName = (SELECT MainName FROM __input); @MainValue = (SELECT MainValue FROM __input); @SubValue = (SELECT SubValue FROM __input); @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = @MainName); UPDATE MainTable SET Value = @MainValue WHERE Id = @MainId; UPDATE SubTable SET Value = @SubValue WHERE MainId = @MainId; END; CREATE PROCEDURE SelectItems ( MainName VARCHAR ( 20 ), CalculatedValue INTEGER OUTPUT ) BEGIN DECLARE @MainName VARCHAR ( 20 ); @MainName = (SELECT MainName FROM __input); INSERT INTO __output SELECT m.Value * s.Value FROM MainTable m INNER JOIN SubTable s ON m.Id = s.MainId WHERE m.Name = @MainName; END; CREATE PROCEDURE DeleteItems ( MainName VARCHAR ( 20 ) ) BEGIN DECLARE @MainName VARCHAR ( 20 ); DECLARE @MainId INTEGER; @MainName = (SELECT MainName FROM __input); @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = @MainName); DELETE FROM SubTable WHERE MainId = @MainId; DELETE FROM MainTable WHERE Id = @MainId; END; Actually, the problem I had - even so light stored procedures work very-very slow (about 50-150 ms) relatively to plain queries (0-5ms). To test the performance, I created a simple test (in F# using ADS ADO.NET provider): open System; open System.Data; open System.Diagnostics; open Advantage.Data.Provider; let mainName = "main name #"; let subName = "sub name #"; // INSERT let cmdTextScriptInsert = " DECLARE @MainId INTEGER; DECLARE @SubId INTEGER; @MainId = (SELECT MAX(Id)+1 FROM MainTable); @SubId = (SELECT MAX(Id)+1 FROM SubTable ); INSERT INTO MainTable (Id, Name, Value) VALUES (@MainId, :MainName, :MainValue); INSERT INTO SubTable (Id, Name, MainId, Value) VALUES (@SubId, :SubName, @MainId, :SubValue); SELECT @MainId, @SubId FROM system.iota;"; let cmdTextProcedureInsert = "CreateItems"; // UPDATE let cmdTextScriptUpdate = " DECLARE @MainId INTEGER; @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = :MainName); UPDATE MainTable SET Value = :MainValue WHERE Id = @MainId; UPDATE SubTable SET Value = :SubValue WHERE MainId = @MainId;"; let cmdTextProcedureUpdate = "UpdateItems"; // SELECT let cmdTextScriptSelect = " SELECT m.Value * s.Value FROM MainTable m INNER JOIN SubTable s ON m.Id = s.MainId WHERE m.Name = :MainName;"; let cmdTextProcedureSelect = "SelectItems"; // DELETE let cmdTextScriptDelete = " DECLARE @MainId INTEGER; @MainId = (SELECT TOP 1 Id FROM MainTable WHERE Name = :MainName); DELETE FROM SubTable WHERE MainId = @MainId; DELETE FROM MainTable WHERE Id = @MainId;"; let cmdTextProcedureDelete = "DeleteItems"; let cnnStr = @"data source=D:\DB\test.add; ServerType=local; user id=adssys; password=***;"; let cnn = new AdsConnection(cnnStr); try cnn.Open(); let cmd = cnn.CreateCommand(); let parametrize ix prms = cmd.Parameters.Clear(); let addParam = function | "MainName" -> cmd.Parameters.Add(":MainName" , mainName + ix.ToString()) |> ignore; | "SubName" -> cmd.Parameters.Add(":SubName" , subName + ix.ToString() ) |> ignore; | "MainValue" -> cmd.Parameters.Add(":MainValue", ix * 3 ) |> ignore; | "SubValue" -> cmd.Parameters.Add(":SubValue" , ix * 7 ) |> ignore; | _ -> () prms |> List.iter addParam; let runTest testData = let (cmdType, cmdName, cmdText, cmdParams) = testData; let toPrefix cmdType cmdName = let prefix = match cmdType with | CommandType.StoredProcedure -> "Procedure-" | CommandType.Text -> "Script -" | _ -> "Unknown -" in prefix + cmdName; let stopWatch = new Stopwatch(); let runStep ix prms = parametrize ix prms; stopWatch.Start(); cmd.ExecuteNonQuery() |> ignore; stopWatch.Stop(); cmd.CommandText <- cmdText; cmd.CommandType <- cmdType; let startId = 1500; let count = 10; for id in startId .. startId+count do runStep id cmdParams; let elapsed = stopWatch.Elapsed; Console.WriteLine("Test '{0}' - total: {1}; per call: {2}ms", toPrefix cmdType cmdName, elapsed, Convert.ToInt32(elapsed.TotalMilliseconds)/count); let lst = [ (CommandType.Text, "Insert", cmdTextScriptInsert, ["MainName"; "SubName"; "MainValue"; "SubValue"]); (CommandType.Text, "Update", cmdTextScriptUpdate, ["MainName"; "MainValue"; "SubValue"]); (CommandType.Text, "Select", cmdTextScriptSelect, ["MainName"]); (CommandType.Text, "Delete", cmdTextScriptDelete, ["MainName"]) (CommandType.StoredProcedure, "Insert", cmdTextProcedureInsert, ["MainName"; "SubName"; "MainValue"; "SubValue"]); (CommandType.StoredProcedure, "Update", cmdTextProcedureUpdate, ["MainName"; "MainValue"; "SubValue"]); (CommandType.StoredProcedure, "Select", cmdTextProcedureSelect, ["MainName"]); (CommandType.StoredProcedure, "Delete", cmdTextProcedureDelete, ["MainName"])]; lst |> List.iter runTest; finally cnn.Close(); And I'm getting the following results: Test 'Script -Insert' - total: 00:00:00.0292841; per call: 2ms Test 'Script -Update' - total: 00:00:00.0056296; per call: 0ms Test 'Script -Select' - total: 00:00:00.0051738; per call: 0ms Test 'Script -Delete' - total: 00:00:00.0059258; per call: 0ms Test 'Procedure-Insert' - total: 00:00:01.2567146; per call: 125ms Test 'Procedure-Update' - total: 00:00:00.7442440; per call: 74ms Test 'Procedure-Select' - total: 00:00:00.5120446; per call: 51ms Test 'Procedure-Delete' - total: 00:00:01.0619165; per call: 106ms The situation with the remote server is much better, but still a great gap between plaqin queries and stored procedures: Test 'Script -Insert' - total: 00:00:00.0709299; per call: 7ms Test 'Script -Update' - total: 00:00:00.0161777; per call: 1ms Test 'Script -Select' - total: 00:00:00.0258113; per call: 2ms Test 'Script -Delete' - total: 00:00:00.0166242; per call: 1ms Test 'Procedure-Insert' - total: 00:00:00.5116138; per call: 51ms Test 'Procedure-Update' - total: 00:00:00.3802251; per call: 38ms Test 'Procedure-Select' - total: 00:00:00.1241245; per call: 12ms Test 'Procedure-Delete' - total: 00:00:00.4336334; per call: 43ms Is it any chance to improve the SP performance?

• Some DHCP clients end up with wrong DNS server

  - by Nic Waller

  The scenario: DC running Windows Server 2008 R2 providing DNS + DHCP Cisco 1811 Router as the gateway 30 Windows XP DHCP clients on the LAN The problem: Some workstations are spontaneously switching to an incorrect DNS server. Specifically, ipconfig /all shows that they start using the gateway as a DNS server. This happens about 5-10 times a day to various computers, sometimes more than once per day. The workaround: Repairing the connection on the XP client always fixes the problem, and the correct DNS server address is obtained. We lost our main DNS/DHCP machine a week ago, and had to bring this one online as a spare. We've been having this issue since then. DHCP leases on the old and new servers are configured for "wired" (8 day) duration. There are definitely no other DHCP servers active on the LAN. So far there is no discernible pattern about which clients will show this problem, or when. When I ran DCDIAG /test:DNS it came back clean. Manual inspection of the DNS zone shows that all the records are appearing as expected, with no traces of the previous machine in there. Update Feb 27: Added screenshots. Here is a screenshot of the DHCP scope options on the 2008 R2 server. And here is a screenshot of ipconfig /all running on a healthy host. I don't have any ailing hosts at the moment, but will grab a screencap next time it happens. Update Feb 28: More screenshots. Here's a screenshot of DHCP and DNS traffic from a healthy client when repairing the local area connection. There's definitely only one server responding, but it does seem strange that the negotiation takes place twice. I'll try to get a similar capture from a sick machine this coming week. Update Mar 01: Caught a bad ipconfig. Here's a screenshot of ipconfig /all from a client that had this issue. It says the lease was issued this morning, but it doesn't even have an entry for the secondary DNS I set up yesterday. Both DNS servers were discovered properly when repairing the connection. Update Mar 01: It even got the sysadmin! This issue finally affected my personal workstation this morning. Unfortunately I had just rebooted and wasn't running a packet dump at the time. I set up a secondary server yesterday, and was logging all DNS traffic to it. My machine had not contacted the secondary DNS in over half an hour, so that says to me that it's just spontaneously reverting to the gateway without even failing over to secondary DNS first. Today I swapped the order of the DNS servers in DHCP, so the secondary is primary and vice versa. I will update again once I know how that goes.

• Forward all traffic through an ssh tunnel

  - by Eamorr

  I hope someone can follow this and I'll explain as best I can. I'm trying to forward all traffic from port 6999 on x.x.x.224, through an ssh tunnel, and onto port 7000 on x.x.x.218. Here is some ASCII art: |browser|-----|Squid on x.x.x.224|------|ssh tunnel|------<satellite link>-----|Squid on x.x.x.218|-----|www| 3128 6999 7000 80 When I remove the ssh tunnel, everything works fine. The idea is to turn off encryption on the ssh tunnel (to save bandwidth) and turn on maximum compression (to save more bandwidth). This is because it's a satellite link. Here's the ssh tunnel I've been using: ssh -C -f -C -o CompressionLevel=9 -o Cipher=none [email protected] -L 7000:172.16.1.224:6999 -N The trouble is, I don't know how to get data from Squid on x.x.x.224 into the ssh tunnel? Am I going about this the wrong way? Should I create an ssh tunnel on x.x.x.218? I use iptables to stop squid on x.x.x.224 from reading port 80, but to feed from port 6999 instead (i.e. via the ssh tunnel). Do I need another iptables rule? Any comments greatly appreciated. Many thanks in advance, Regarding Eduardo Ivanec's question, here is a netstat -i any port 7000 -nn dump from x.x.x.218: 14:42:15.386462 IP 172.16.1.224.40006 > 172.16.1.218.7000: Flags [S], seq 2804513708, win 14600, options [mss 1460,sackOK,TS val 86702647 ecr 0,nop,wscale 4], length 0 14:42:15.386690 IP 172.16.1.218.7000 > 172.16.1.224.40006: Flags [R.], seq 0, ack 2804513709, win 0, length 0 Update 2: When I run the second command, I get the following error in my browser: ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://109.123.109.205/index.php Zero Sized Reply Squid did not receive any data for this request.

• Issue with Netgear GS108T Managed Switch and Jumbo Frames

  - by Richie086

  I recently purchased a Netgear GS108T managed switch and I am trying to configure jumbo packets between my NAS (Thecus N4100Pro), PC and managed switch. I should mention the fact that I was able to use jumbo frames between my PC and NAS before I purchased the switch without issue. My Desktop has a wired gigabit NIC (Intel 82579V Gigabit) and has the ability to configure jumbo frames (see pic) that are either 9014 bytes or 4088 bytes. I choose 9014 bytes for the jumbo frame size My NAS supports jumbo frames as well, and is configured to use 9014 as the frame size. When I go into my Netgear managed switch and set the frame size to 9014 on the ports I am using for my PC and NAS. See image As soon as I hit apply in the web interface, I loose my connection to the SMB shares on my NAS and I can no longer connect to the web admin interface for my NAS. The really strange thing is I can ping my NAS via the ping command, but when I try to connect to the web interface on port 80 or port 443 the page never loads. I did a scan from my PC to my NAS using nmap and I can see the following ports open PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 111/tcp open rpcbind 139/tcp open netbios-ssn 443/tcp open https 445/tcp open microsoft-ds 631/tcp open ipp 2000/tcp open cisco-sccp 2049/tcp open nfs 3260/tcp open iscsi 49152/tcp open unknown MAC Address: 00:14:FD:15:00:44 (Thecus Technology) Read data files from: C:\Program Files (x86)\Nmap Nmap done: 1 IP address (1 host up) scanned in 211.97 seconds Raw packets sent: 1 (28B) | Rcvd: 1 (28B) Anyone have any idea what is going on here? Why is nmap able to detect the ports are open and listening for http, https and file sharing but I cant connect when all devices have jumbo packets enabled? Stranger still - I did a packet capture using wireshark while the nmap scan was running and filtered so I only saw converstations between my PC and my NAS. Here are the packet details from my scan Only 4 packets over 5k bytes? What is going on here? Do I not need to configure jumbo frame sizes on the switch? I have an internet connection from my pc to the switch to my router - I just cannot connect to my NAS. I just checked on my iPhone and I am able to open my NAS web admin interface without issue on my iPhone! WTF!!!!!! Let me know if you need more details..

• Profiles and using the local profile for a domain user

  - by Harry

  I’m having some trouble with profiles and would like to reach out for some help. I’ve tried to do some research to help myself along, but I’m not making much progress on my own. I’ve pretty much taken over the sys admin duties for my small lab, I don’t have much experience to justify it besides I’m the only with the time and dedication to go at it (The environment was in a state of disrepair). My network and domain I look over are extremely small by most standards, about 10 users at a time. They are pretty intensive activity on the network, and we do work with fairly large files. None of the network is online, which is nice at the moment because it allows me not to have another headache. On to my profile problem, I have set up roaming profiles for the users in the network. Now after a little research, I think I will be switching this to a hybrid of folder redirection and roaming profiles as this seems to best practice. I also don’t want the users having to wait for a long time if they have a bloated profile. Now I’ve finally got a build working using MDT. We have Mac Pros, and it wasn’t fun getting everything to play nice. The way I did this was by setting up a reference computer and installing all the software and tools that each user would need and editing the settings preferences to how we would need them. I think used MDT to do a sys prep and capture to create the image of my reference computer. Using the reference image I can push out my images to the rest of the desktops in my environment. The issue I’m having is when we join the computer to domain. The user can login and operate fine on the computer, but I’d like a more. When the user is logged on with their domain user name they lose a lot of the icons I had on my reference image, as well as the desktop background and some other miscellaneous settings. I would love to have the user log on using their domain user name and see the icons and desktop environment as I had it setup on the reference computer. I’m not sure if it is possible, or something simple that I’m missing, but any help would be greatly appreciated!

• MySQL is running VERY slow on CentOS 6x (not 5x)

  - by user1032531

  I have two servers: a VPS and a laptop. I recently re-built both of them, and MySQL is running about 20 times slower on the laptop. Both servers used to run CentOS 5.8 and I think MySQL 5.1, and the laptop used to do great so I do not think it is the hardware. For the VPS, my provider installed CentOS 6.4, and then I installed MySQL 5.1.69 using yum with the CentOS repo. For the laptop, I installed CentOS 6.4 basic server and then installed MySQL 5.1.69 using yum with the CentOS repo. my.cnf for both servers are identical, and I have shown below. For both servers, I've also included below the output from SHOW VARIABLES; as well as output from sysbench, file system information, and cpu information. I have tried adding skip-name-resolve, but it didn't help. The matrix below shows the SHOW VARIABLES output from both servers which is different. Again, MySQL was installed the same way, so I do not know why it is different, but it is and I think this might be why the laptop is executing MySQL so slowly. Why is the laptop running MySQL slowly, and how do I fix it?

• IPsec tunnel to Android device not created even though there is an IKE SA

  - by Quentin Swain

  I'm trying to configure a VPN tunnel between an Android device running 4.1 and a Fedora 17 Linux box running strongSwan 5.0. The device reports that it is connected and strongSwan statusall returns that there is an IKE SA, but doesn't display a tunnel. I used the instructions for iOS in the wiki to generate certificates and configure strongSwan. Since Android uses a modified version of racoon this should work and since the connection is partly established I think I am on the right track. I don't see any errors about not being able to create the tunnel. This is the configuration for the strongSwan connection conn android2 keyexchange=ikev1 authby=xauthrsasig xauth=server left=96.244.142.28 leftsubnet=0.0.0.0/0 leftfirewall=yes leftcert=serverCert.pem right=%any rightsubnet=10.0.0.0/24 rightsourceip=10.0.0.2 rightcert=clientCert.pem ike=aes256-sha1-modp1024 auto=add This is the output of strongswan statusall Status of IKE charon daemon (strongSwan 5.0.0, Linux 3.3.4-5.fc17.x86_64, x86_64): uptime: 20 minutes, since Oct 31 10:27:31 2012 malloc: sbrk 270336, mmap 0, used 198144, free 72192 worker threads: 8 of 16 idle, 7/1/0/0 working, job queue: 0/0/0/0, scheduled: 7 loaded plugins: charon aes des sha1 sha2 md5 random nonce x509 revocation constraints pubkey pkcs1 pkcs8 pgp dnskey pem openssl fips-prf gmp xcbc cmac hmac attr kernel-netlink resolve socket-default stroke updown xauth-generic Virtual IP pools (size/online/offline): android-hybrid: 1/0/0 android2: 1/1/0 Listening IP addresses: 96.244.142.28 Connections: android-hybrid: %any...%any IKEv1 android-hybrid: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android-hybrid: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android-hybrid: remote: [%any] uses XAuth authentication: any android-hybrid: child: dynamic === dynamic TUNNEL android2: 96.244.142.28...%any IKEv1 android2: local: [C=CH, O=strongSwan, CN=vpn.strongswan.org] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=vpn.strongswan.org" android2: remote: [C=CH, O=strongSwan, CN=client] uses public key authentication android2: cert: "C=CH, O=strongSwan, CN=client" android2: remote: [%any] uses XAuth authentication: any android2: child: 0.0.0.0/0 === 10.0.0.0/24 TUNNEL Security Associations (1 up, 0 connecting): android2[3]: ESTABLISHED 10 seconds ago, 96.244.142.28[C=CH, O=strongSwan, CN=vpn.strongswan.org]...208.54.35.241[C=CH, O=strongSwan, CN=client] android2[3]: Remote XAuth identity: android android2[3]: IKEv1 SPIs: 4151e371ad46b20d_i 59a56390d74792d2_r*, public key reauthentication in 56 minutes android2[3]: IKE proposal: AES_CBC_256/HMAC_SHA1_96/PRF_HMAC_SHA1/MODP_1024 The output of ip -s xfrm policy src ::/0 dst ::/0 uid 0 socket in action allow index 3851 priority 0 ptype main share any flag (0x00000000) lifetime config: limit: soft 0(bytes), hard 0(bytes) limit: soft 0(packets), hard 0(packets) expire add: soft 0(sec), hard 0(sec) expire use: soft 0(sec), hard 0(sec) lifetime current: 0(bytes), 0(packets) add 2012-10-31 13:29:08 use -

• PHP SOAP error: Method element needs to belong to the namespace

  - by kdm

  I'm unable to retrieve data from an XML document, any help is greatly appreciated. I'm using PHP 5.2.10 and the WSDL url is an internal link within my company. The following code produces an error. $url = "http://dta-info/IVR/IVRINFO?WSDL"; $params = array("zANI" => "12345"); try{ $client = new SoapClient($url, array( 'trace' => 1, 'connection_timeout' => 2, 'location' => $url ) ); }catch(SoapFault $fault){ echo "faultstring: {$fault->faultstring})\n"; } try{ $result = $client->GetIVRinfo($params); }catch(SoapFault $fault){ echo "(faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring} )\n"; } (faultcode: SOAP-ENV:Client, faultstring: There should be no path or parameters after a SOAP vname. ) So i tried to use a non-wsdl mode but i receive a different error no matter how i try to format the params. $url = "http://dta-info/IVR/IVRINFO"; $params = array("zANI" => "12345"); try{ $client = new SoapClient(null, array( 'trace' => 1, 'connection_timeout' => 2, 'location' => $url, 'uri' => $uri, 'style' => SOAP_DOCUMENT, 'use' => SOAP_LITERAL, 'soap_version' => SOAP_2 ) ); }catch(SoapFault $fault){ echo "faultstring: {$fault->faultstring})\n"; } try{ $result = $client->GetIVRinfo($params); }catch(SoapFault $fault){ echo "(faultcode: {$fault->faultcode}, faultstring: {$fault->faultstring} )\n"; } (faultcode: SOAP-ENV:Client, faultstring: The method element needs to belong to the namespace 'http://GETIVRINFO/IVR/IVRINFO'. ) I have tested this WSDL with a tool called SoapUI and it returns the results with no errors. So it leads me to believe I'm not formatting the vars or headers correctly with PHP. I also tried passing in a xml fragment as the param but that returns the same error. What am i doing wrong?????? $params = '<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ivr="http://GETIVRINFO/IVR/IVRINFO"> <soapenv:Header/> <soapenv:Body>

• Providing DNS redirection to honeypot server for known bad domains

  - by syn-

  Currently running BIND on RHEL 5.4 and am looking for a more efficient manner of providing DNS redirection to a honeypot server for a large (30,000+) list of forbidden domains. Our current solution for this requirement is to include a file containing a zone master declaration for each blocked domain in named.conf. Subsequently, each of these zone declarations point to the same zone file, which resolves all hosts in that domain to our honeypot servers. ...basically this allows us to capture any "phone home" attempts by malware that may infiltrate the internal systems. The problem with this configuration is the large amount of time taken to load all 30,000+ domains as well as management of the domain list configuration file itself... if any errors creep into this file, the BIND server will fail to start, thereby making automation of the process a little frightening. So I'm looking for something more efficient and potentially less error prone. named.conf entry: include "blackholes.conf"; blackholes.conf entry example: zone "bad-domain.com" IN { type master; file "/var/named/blackhole.zone"; allow-query { any; }; notify no; }; blackhole.zone entries: $INCLUDE std.soa @ NS ns1.ourdomain.com. @ NS ns2.ourdomain.com. @ NS ns3.ourdomain.com.                        IN            A                192.168.0.99 *                      IN            A                192.168.0.99

• Filtering Security Logs by User and Logon Type

  - by Trido

  I have been asked to find out when a user has logged on to the system in the last week. Now the audit logs in Windows should contain all the info I need. I think if I search for Event ID 4624 (Logon Success) with a specific AD user and Logon Type 2 (Interactive Logon) that it should give me the information I need, but for the life of my I cannot figure out how to actually filter the Event Log to get this information. Is it possible inside of the Event Viewer or do you need to use an external tool to parse it to this level? I found http://nerdsknowbest.blogspot.com.au/2013/03/filter-security-event-logs-by-user-in.html which seemed to be part of what I needed. I modified it slightly to only give me the last 7 days worth. Below is the XML I tried. <QueryList> <Query Id="0" Path="Security"> <Select Path="Security">*[System[(EventID=4624) and TimeCreated[timediff(@SystemTime) &lt;= 604800000]]]</Select> <Select Path="Security">*[EventData[Data[@Name='Logon Type']='2']]</Select> <Select Path="Security">*[EventData[Data[@Name='subjectUsername']='Domain\Username']]</Select> </Query> </QueryList> It only gave me the last 7 days, but the rest of it did not work. Can anyone assist me with this? EDIT Thanks to the suggestions of Lucky Luke I have been making progress. The below is my current query, although as I will explain it isn't returning any results. <QueryList> <Query Id="0" Path="Security"> <Select Path="Security"> *[System[(EventID='4624')] and System[TimeCreated[timediff(@SystemTime) &lt;= 604800000]] and EventData[Data[@Name='TargetUserName']='john.doe'] and EventData[Data[@Name='LogonType']='2'] ] </Select> </Query> </QueryList> As I mentioned, it wasn't returning any results so I have been messing with it a bit. I can get it to produce the results correctly until I add in the LogonType line. After that, it returns no results. Any idea why this might be? EDIT 2 I updated the LogonType line to the following: EventData[Data[@Name='LogonType'] and (Data='2' or Data='7')] This should capture Workstation Logons as well as Workstation Unlocks, but I still get nothing. I then modify it to search for other Logon Types like 3, or 8 which it finds plenty of. This leads me to believe that the query works correctly, but for some reason there are no entries in the Event Logs with Logon Type equalling 2 and this makes no sense to me. Is it possible to turn this off?

• Forwarding RDP via a Linux machine using iptables: Not working

  - by Nimmy Lebby

  I have a Linux machine and a Windows machine behind a router that implements NAT (the diagram might be overkill, but was fun to make): I am forwarding RDP port (3389) on the router to the Linux machine because I want to audit RDP connections. For the Linux machine to forward RDP traffic, I wrote these iptables rules: iptables -t nat -A PREROUTING -p tcp --dport 3389 -j DNAT --to-destination win-box iptables -A FORWARD -p tcp --dport 3389 -j ACCEPT The port is listening on the Windows machine: C:\Users\nimmy>netstat -a Active Connections Proto Local Address Foreign Address State (..snip..) TCP 0.0.0.0:3389 WIN-BOX:0 LISTENING (..snip..) And the port is forwarding on the Linux machine: # tcpdump port 3389 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 01:33:11.451663 IP shieldsup.grc.com.56387 > linux-box.myapt.lan.ms-wbt-server: Flags [S], seq 94663035, win 8192, options [mss 1460], length 0 01:33:11.451846 IP shieldsup.grc.com.56387 > win-box.myapt.lan.ms-wbt-server: Flags [S], seq 94663035, win 8192, options [mss 1460], length 0 However, I am not getting any successful RDP connections from the outside. The port is not even responding: C:\Users\outside-nimmy>telnet example.com 3389 Connecting To example.com...Could not open connection to the host, on port 3389: Connect failed Any ideas? Update Per @Zhiqiang Ma, I looked at nf_conntrack proc file during a connection attempt and this is what I see (192.168.3.1 = linux-box, 192.168.3.5 = win-box): # cat /proc/net/nf_conntrack | grep 3389 ipv4 2 tcp 6 118 SYN_SENT src=4.79.142.206 dst=192.168.3.1 sport=43142 dport=3389 packets=6 bytes=264 [UNREPLIED] src=192.168.3.5 dst=4.79.142.206 sport=3389 dport=43142 packets=0 bytes=0 mark=0 secmark=0 zone=0 use=2 2nd update Got tcpdump on the router and it seems that win-box is sending an RST packet: 21:20:24.767792 IP shieldsup.grc.com.45349 > linux-box.myapt.lan.3389: S 19088743:19088743(0) win 8192 <mss 1460> 21:20:24.768038 IP shieldsup.grc.com.45349 > win-box.myapt.lan.3389: S 19088743:19088743(0) win 8192 <mss 1460> 21:20:24.770674 IP win-box.myapt.lan.3389 > shieldsup.grc.com.45349: R 721745706:721745706(0) ack 755785049 win 0 Why would Windows be doing this?

• Why would a WebService return nulls when the actual service returns data?

  - by Jerry

  I have a webservice (out of my control) that I have to talk to. I also have a packet-sniffer on the line, and (SURPRISE!!!) the developers of the webservice aren't lying. They are actually sending back all of the data that I requested. But the web-service code that is auto-generated from the WSDL file is giving me "null" as a value. I used their WSDL file to generate my Web Reference. I checked my data types with the datatypes that the WSDL file has declared. And I used the code as listed below to perform the calls: DT_MaterialMaster_LookupRequest req = new DT_MaterialMaster_LookupRequest(); req.MaterialNumber = "101*"; req.DocumentNo = ""; req.Description = "Pipe*"; req.Plant = "0000"; MI_MaterialMaster_Lookup_OBService srv = new MI_MaterialMaster_Lookup_OBService(); DT_MaterialMaster_Response resp = srv.MI_MaterialMaster_Lookup_OB(new DT_MaterialMaster_LookupRequest[] { req }); // Note that the response here is ALWAYS null!! Console.WriteLine(resp.Status); The resp object is an actual object. It was generated properly. However, the Status and MaterialData fields are always null. When I call the web service, I've placed a packet-sniffer on the line, and I can see that I've sent the following (linebreaks and indentions for my own sanity): <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <soap:Body> <MT_MaterialMaster_Lookup xmlns="http://MyCompany.com/SomeCompany/mm/MaterialMasterSearch"> <Request xmlns=""> <MaterialNumber>101*</MaterialNumber> <Description>Pipe*</Description> <DocumentNo /> <Plant>0000</Plant> </Request> </MT_MaterialMaster_Lookup> </soap:Body> </soap:Envelope> The response that they send back SEEMS to be a valid response (linebreaks and indentions for my own sanity): <SOAP:Envelope xmlns:SOAP='http://schemas.xmlsoap.org/soap/envelope/'> <SOAP:Header /> <SOAP:Body> <n0:MT_MaterialMaster_Response xmlns:n0='http://MyCompany.com/SomeCompany/mm/MaterialMasterSearch' xmlns:prx='urn:SomeCompany.com:proxy:BRD:/1SAI/TAS4FE14A2DE960D61219AE:701:2009/02/10'> <Response> <Status>No Rows Found</Status> <MaterialData /> </Response> </n0:MT_MaterialMaster_Response> </SOAP:Body> </SOAP:Envelope> The status shows that it actually received data... but the resp.Status and resp.MaterialData fields are always null.

• How to know the source of certain TCP traffic on AIX

  - by A.Rashad

  We have two AIX boxes, one for production system and another for testing. both systems are running ATM machine switches, where the ATM device is connected via TCP socket. we had an issue on production system where the machine would power off or get disconnected but the netstat -na | grep <IP of machine > would still mention that the socket is up when simulated that case on the UAT environment, the problem did not happen, where the socket would terminate in 3 to 5 minutes. when sniffed on the traffic between the machine and ATM we found that no traffic takes place on production while there is some sort of heartbeat on UAT. but it is not initiated by the application. $>tcpdump | grep -v "10.2.2.71" | grep -v "HSRP" | grep "10.3.1.30" tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on en6, link-type 1, capture size 96 bytes 09:08:13.323421 IP server073.afs3-callback > 10.3.1.30.impera: . 278204201:278204202(1) ack 3307884029 win 164 09:08:13.335334 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:08:23.425771 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:08:23.425789 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 09:09:13.628985 IP server073.afs3-callback > 10.3.1.30.impera: . 0:1(1) ack 1 win 164 09:09:13.633900 IP 10.3.1.30.impera > server073.afs3-callback: . ack 1 win 64180 09:09:23.373634 IP 10.3.1.30.impera > server073.afs3-callback: . 1:2(1) ack 1 win 64180 09:09:23.373647 IP server073.afs3-callback > 10.3.1.30.impera: . ack 2 win 65535 while on production, that traffic is not there. we want to know where this traffic is initiated from to implement on production to sense disconnection our comms parameters are: tcp_keepcnt = 2 tcp_keepidle = 100 tcp_keepinit = 150 tcp_keepintvl = 150 tcp_finwait2 = 1200 can anyone help?

• WinPE, Startnet.CMD and passing variables to second batch file not working

  - by user140892

  I don't know scripting or PowerShell (yes I need to learn something). I'm not an expert batch file maker either. I have a WinPE flash drive which I used to deploy OS images. I have the WIM, drivers and anything needed else outside the WinPE environment to ensure that Updates, changes are easier for me to make. I use the "STARTNET.CMD" batch file which is part of the WinPE. The reason to go through the letter drives is that the WinPE always gets the X letter drive assigned. The flash drive itself can receive a random letter which always changes. My deployment menu is located on the flash drive it self and not inside the WinPE. This is so that if I need to make a change I don't have to re-do the WinPE. I am able to locate the "menu.bat" batch file and launch it. I use a variable to capture the letter drive. I call the second batch file named "menu.bat" and pass the variable to it. When the second batch file loads, I believe that I am calling the variable correctly. If I break out of the batch file I can echo the variable and see the expected reply. The issue is that I can't use the variable to work with anything on the second batch file. In my test, I can get this to work over and over. When it runs from the real USB flash drive it does not work. I removed comments from the second batch file to make it smaller. My issue is that files below all get a message stating that the system cannot find the path specified. Diskpart Imagex.exe bcdboot.exe Why can't I get the varible to properly function when I try to using example "ImageX.exe"?

• Accelerated C++, problem 5-6 (copying values from inside a vector to the front)

  - by Darel

  Hello, I'm working through the exercises in Accelerated C++ and I'm stuck on question 5-6. Here's the problem description: (somewhat abbreviated, I've removed extraneous info.) 5-6. Write the extract_fails function so that it copies the records for the passing students to the beginning of students, and then uses the resize function to remove the extra elements from the end of students. (students is a vector of student structures. student structures contain an individual student's name and grades.) More specifically, I'm having trouble getting the vector.insert function to properly copy the passing student structures to the start of the vector students. Here's the extract_fails function as I have it so far (note it doesn't resize the vector yet, as directed by the problem description; that should be trivial once I get past my current issue.) // Extract the students who failed from the "students" vector. void extract_fails(vector<Student_info>& students) { typedef vector<Student_info>::size_type str_sz; typedef vector<Student_info>::iterator iter; iter it = students.begin(); str_sz i = 0, count = 0; while (it != students.end()) { // fgrade tests wether or not the student failed if (!fgrade(*it)) { // if student passed, copy to front of vector students.insert(students.begin(), it, it); // tracks of the number of passing students(so we can properly resize the array) count++; } cout << it->name << endl; // output to verify that each student is iterated to it++; } } The code compiles and runs, but the students vector isn't adding any student structures to its front. My program's output displays that the students vector is unchanged. Here's my complete source code, followed by a sample input file (I redirect input from the console by typing " < grades" after the compiled program name at the command prompt.) #include <iostream> #include <string> #include <algorithm> // to get the declaration of `sort' #include <stdexcept> // to get the declaration of `domain_error' #include <vector> // to get the declaration of `vector' //driver program for grade partitioning examples using std::cin; using std::cout; using std::endl; using std::string; using std::domain_error; using std::sort; using std::vector; using std::max; using std::istream; struct Student_info { std::string name; double midterm, final; std::vector<double> homework; }; bool compare(const Student_info&, const Student_info&); std::istream& read(std::istream&, Student_info&); std::istream& read_hw(std::istream&, std::vector<double>&); double median(std::vector<double>); double grade(double, double, double); double grade(double, double, const std::vector<double>&); double grade(const Student_info&); bool fgrade(const Student_info&); void extract_fails(vector<Student_info>& v); int main() { vector<Student_info> vs; Student_info s; string::size_type maxlen = 0; while (read(cin, s)) { maxlen = max(maxlen, s.name.size()); vs.push_back(s); } sort(vs.begin(), vs.end(), compare); extract_fails(vs); // display the new, modified vector - it should be larger than // the input vector, due to some student structures being // added to the front of the vector. cout << "count: " << vs.size() << endl << endl; vector<Student_info>::iterator it = vs.begin(); while (it != vs.end()) cout << it++->name << endl; return 0; } // Extract the students who failed from the "students" vector. void extract_fails(vector<Student_info>& students) { typedef vector<Student_info>::size_type str_sz; typedef vector<Student_info>::iterator iter; iter it = students.begin(); str_sz i = 0, count = 0; while (it != students.end()) { // fgrade tests wether or not the student failed if (!fgrade(*it)) { // if student passed, copy to front of vector students.insert(students.begin(), it, it); // tracks of the number of passing students(so we can properly resize the array) count++; } cout << it->name << endl; // output to verify that each student is iterated to it++; } } bool compare(const Student_info& x, const Student_info& y) { return x.name < y.name; } istream& read(istream& is, Student_info& s) { // read and store the student's name and midterm and final exam grades is >> s.name >> s.midterm >> s.final; read_hw(is, s.homework); // read and store all the student's homework grades return is; } // read homework grades from an input stream into a `vector<double>' istream& read_hw(istream& in, vector<double>& hw) { if (in) { // get rid of previous contents hw.clear(); // read homework grades double x; while (in >> x) hw.push_back(x); // clear the stream so that input will work for the next student in.clear(); } return in; } // compute the median of a `vector<double>' // note that calling this function copies the entire argument `vector' double median(vector<double> vec) { typedef vector<double>::size_type vec_sz; vec_sz size = vec.size(); if (size == 0) throw domain_error("median of an empty vector"); sort(vec.begin(), vec.end()); vec_sz mid = size/2; return size % 2 == 0 ?

• Ubuntu with KVM guest VM and broken bridges

  - by MadPsy

  I have an Ubuntu box with a KVM guest VM running. They use bridging so the guest VM attaches to the physical network of its host. The guest VM has 2 NICs in 2 different bridges. First NIC of the VM is tap5 and is in bridge br0 br0 8000.46720f5c572e no eth0.500 tap5 Second NIC of the VM is tap2 and is in bridge br100 br100 8000.76ad2fc96661 no eth0.100 eth0.101 eth0.103 eth0.104 eth0.105 tap2 On the host, br0 has an IP and br100 does not 21: br0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP link/ether 46:72:0f:5c:57:2e brd ff:ff:ff:ff:ff:ff inet 192.168.100.4/24 brd 192.168.10.255 scope global br0 inet6 fe80::d6ae:52ff:febe:777/64 scope link valid_lft forever preferred_lft forever On the guest, its eth0 and eth1 interfaces both have IP addresses 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:3e:61:fb:7a:da brd ff:ff:ff:ff:ff:ff inet 192.168.100.6/24 brd 192.168.100.255 scope global eth0 inet6 fe80::23e:61ff:fefb:7ada/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:3e:61:fb:7a:ea brd ff:ff:ff:ff:ff:ff inet 172.16.50.129/25 brd 172.16.50.255 scope global eth1 inet6 fe80::23e:61ff:fefb:7aea/64 scope link valid_lft forever preferred_lft forever On the guest VM, a tcpdump of its eth1 interface (tap2) shows traffic from its eth0 interface (tap5), as if the 2 bridges are themselves bridged. This means any interface on br100 is now bridged across to br0 - which is completely broken. root@chillispot:~# tcpdump -c 1 -n -v -i eth1 net 192.168.100.0/24 tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes 16:31:24.175583 IP (tos 0x0, ttl 64, id 48054, offset 0, flags [DF], proto TCP (6), length 148) 192.168.100.6.22 > 192.168.100.4.59505: Flags [P.], cksum 0x6c2b (correct), seq 1056321648:1056321744, ack 398642983, win 1700, options [nop,nop,TS val 197473436 ecr 200655363], length 96 What could be bridging the 2 bridges, except the guest VM (which is a stock Ubuntu install)? I am at a complete loss! Thanks.

• Lag spikes at full CPU usage, maybe video card

  - by Roberts

  I am posting this thread in hurry so few things may be missed (I will update tomorrow). My PC specs: Motherboard Name - Gigabyte GA-945PL-S3 CPU Type - DualCore Intel Core 2 Duo E4300, 1800 MHz (9 x 200) OS - Microsoft Windows 7 Ultimate OS Kernel Type - 32-bit OS Version - 6.1.7601 I bougth a new video card one month ago. GeForce 210. I didn't have any problems. I wanted to overclock it, in other words: "Play with it". So I installed Gigabyte EasyBoost from CD and overclocked the GPU 590 + 110 mhz, memory to max to 960mhz from 800mhz. Benchmarks showed a little bit bigger score. Then I overclocked shader clock from 1405 to [..] (don't remeber really). So I was playing Modern Warfare 2 when off sudden computer froze when I wanted to select team, I was afk before that. I had to reset CMOS. After that I had problems with Skype: unread messages and no sound. Then I figured it out that when ever I open EasyBoost - Skype starts to glitch again. Now I use EVGA Precission X. Now after a month, I cleaned computer and closed the case, it was open all the time. I started to overclock GPU clock only (just a bit) because there was no problems that would stop me. So sometimes on heavy CPU load graphics starts to lag. Dragging a window is painful to watch too. Sometimes the screen freezes for 5 to 10 seconds (I can see that hard disk activity is maximal). You may say that CPU fault it is, isn't it? But sometimes lag spikes starts randomly when CPU load is at maximum. All 3 benchmark softwares (PerformanceTest, NovaBench and MSI Kombustor) shows that performance of my video card has dropped about 25%. BUT! CPU score is lower too. I ignored these problems but when I refreshed Windows Experience Index I was shocked. Month before (in latvian language but not so hard to understand): Now (upgraded RAM): This happened when I tried to capture Minecraft with Fraps on underclocked GPU to 580mhz (def: 590mhz): All drivers are up to date. Average CPU temperature from 55°C to 75°C (at 70°C sometimes starts these lag spikes). Video card's tempratures are from 45°C to 60°C (very hard to reach 60°C). So my hope is that the video card is fine, cause this card is very new and I want to upgrade CPU anyways. Aplogies for my mistakes in vocabulary (I am trying to type this as fast I can).

• What Sort of Server Setup Am I Likely to Need? - School A/V streaming

  - by DeathMagus

  My prior experience with servers has generally been limited to home file-sharing servers, low-traffic web-servers, and the like. This leaves me with the technical knowledge of how to set up a system, but little experience in terms of scaling said system. My current project, however, has me as the technical lead in setting up a school for online audio and video streaming. The difficulty I'm running into is that I don't quite have the experience to guess what they'll need, and they don't have the experience to tell me - so I've tried to ask as many pertinent questions about what they want to do with their server, and here's what I found out: About 1000 simultaneous users, and hoping to expand (possibly significantly) Both video and audio streaming, at obviously the highest quality possible Support for both live and playlist-based streaming. Probably only one channel, but as it's an educational opportunity, I imagine letting them have a few more wouldn't hurt. No word on whether they're locked into Windows or whether Linux is acceptable. Approximate budget - $7000. It may actually be about $2k less than this, because of a mishap with another technology firm (they ordered a $7000 DV tape deck for some reason, and now the company wants them to pay a 30% restocking fee). The tentative decisions I've already made: I'm planning on using Icecast 2 for my streaming server, fed by VLC Shoutcast encoding. Since the school already has a DMZ set up, I plan on placing the Icecast server in there, and feeding it through their intranet from a simple workstation computer in their studios. This system isn't in any way mission critical - it's an education tool (they're a media magnet school), so I figure redundancy is not worthwhile to them from a cost:benefit perspective. What I don't know is this: How powerful of a server will I need? What is likely to be my major throttle - bandwidth? How can I mitigate that? Will I need anything special for the encoding workstation other than professional video and audio capture cards and a copy of VLC? Are there any other considerations that I'm simply missing? Thanks a lot for any help - if there's more information you need, let me know and I'll tell you all I can.

• Lots of dropped packages when tcpdumping on busy interface

  - by Frands Hansen

  My challenge I need to do tcpdumping of a lot of data - actually from 2 interfaces left in promiscuous mode that are able to see a lot of traffic. To sum it up Log all traffic in promiscuous mode from 2 interfaces Those interfaces are not assigned an IP address pcap files must be rotated per ~1G When 10 TB of files are stored, start truncating the oldest What I currently do Right now I use tcpdump like this: tcpdump -n -C 1000 -z /data/compress.sh -i any -w /data/livedump/capture.pcap $FILTER The $FILTER contains src/dst filters so that I can use -i any. The reason for this is, that I have two interfaces and I would like to run the dump in a single thread rather than two. compress.sh takes care of assigning tar to another CPU core, compress the data, give it a reasonable filename and move it to an archive location. I cannot specify two interfaces, thus I have chosen to use filters and dump from any interface. Right now, I do not do any housekeeping, but I plan on monitoring disk and when I have 100G left I will start wiping the oldest files - this should be fine. And now; my problem I see dropped packets. This is from a dump that has been running for a few hours and collected roughly 250 gigs of pcap files: 430083369 packets captured 430115470 packets received by filter 32057 packets dropped by kernel <-- This is my concern How can I avoid so many packets being dropped? These things I did already try or look at Changed the value of /proc/sys/net/core/rmem_max and /proc/sys/net/core/rmem_default which did indeed help - actually it took care of just around half of the dropped packets. I have also looked at gulp - the problem with gulp is, that it does not support multiple interfaces in one process and it gets angry if the interface does not have an IP address. Unfortunately, that is a deal breaker in my case. Next problem is, that when the traffic flows though a pipe, I cannot get the automatic rotation going. Getting one huge 10 TB file is not very efficient and I don't have a machine with 10TB+ RAM that I can run wireshark on, so that's out. Do you have any suggestions? Maybe even a better way of doing my traffic dump altogether.
