• KVM network bridge and public static IP for both host and guests

  - by Javier Martinez

  I have a Debian Server with 4 public static addresses. There is a KVM guest (also Debian) installed and running. What I want is to give the guest an IP of the host, so that both machines have public IPs. IP 1: 188.165.A.B IP 2: 178.33.CCC.D IP 3: 178.33.CCC.E IP 4: 178.33.CCC.F What should I do to have connection for host and guest ?

• Conflicting ip routes with local table on attaching a virtual network interface

  - by user1071840

  I have an EC2 instance with these ip rules: $ sudo ip rule show 0: from all lookup local 32766: from all lookup main 32767: from all lookup default I can attach an elastic network interface to it with a private IP. Say the IP of my machine is 10.1.3.12 and the IP of the interface is 10.1.1.190. As soon as I attach the interface to my machine a new entry is added to the routing policy and local routing table: sudo ip rule show 0: from all lookup local 32765: from 10.1.1.190 lookup 10003 32766: from all lookup main 32767: from all lookup default $ sudo ip route show table local broadcast 10.1.1.0 dev eth3 proto kernel scope link src 10.1.1.190 local 10.1.1.190 dev eth3 proto kernel scope host src 10.1.1.190 broadcast 10.1.1.255 dev eth3 proto kernel scope link src 10.1.1.190 broadcast 10.1.3.0 dev eth0 proto kernel scope link src 10.1.3.12 local 10.1.3.12 dev eth0 proto kernel scope host src 10.1.3.12 broadcast 10.1.3.255 dev eth0 proto kernel scope link src 10.1.3.12 broadcast 127.0.0.0 dev lo proto kernel scope link src 127.0.0.1 local 127.0.0.0/8 dev lo proto kernel scope host src 127.0.0.1 local 127.0.0.1 dev lo proto kernel scope host src 127.0.0.1 broadcast 127.255.255.255 dev lo proto kernel scope link src 127.0.0.1 I can send traffic to this ENI directly from a host that can have the same IP as the host the ENI is attached to. This is where the problem starts. I ran tcpdump on the port in question and saw multiple SYNs going to the ENI with src '10.1.3.12' and destination '10.1.1.190' but didn't see even a single ACK. In my understanding if ACKs were being sent from the ENI they'd have destination as 10.1.3.12 i.e. the same as the local machine's IP and such packets will now be routed as local packets matching local routing policy: local 10.1.3.12 dev eth0 proto kernel scope host src 10.1.3.12 I'd like to send all the packets originating from 10.1.1.190 (my ENI) to go back on the same interface i.e. eth3 in this case. Contents of the nee table 10003 are: $ sudo ip route show table 10003 default via 10.1.1.1 dev eth3 I think I can do the following: I don't know if its possible but probably decrease the priority of local table so the packets match the table 10003. Use iptables to mangle these packets and update the local table route to include the mark information But I'm not sure if these are the right approaches.

• Configure server on network to analyze traffic

  - by Strajan Sebastian

  I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While searching on the Internet for some similar configuration I found some articles that are somehow related to my needs, but the proposed solutions don't seem to work for me. This is a similar article: iptables forwarding between two interface I done the following steps for the configuration process: Set static IP address 192.168.1.90 for the eth0 on the server from the 192.168.1.1 router Set static IP address 192.168.0.90 for the eth1 on the server from the 192.168.0.1 router Forwarded all the traffic from 192.168.0.1 router to the server on eth1 interface witch seems to be working. The router firmware has some option to redirect all the traffic from all the ports to a specified address. Added the following rules on the server(Only the following, there aren't any additional rules): iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT I also tried changing iptables -A FORWARD -i eth1 -o eth0 -m state -–state RELATED,ESTABLISHED -j ACCEPT into iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT but still is not working. After adding the following to enable the packet forwarding for the server that is running CentOS: echo 1 /proc/sys/net/ipv4/ip_forward sysctl -w net.ipv4.ip_forward = 1 After a server restart and extra an extra check to see that all the configuration from above are still available I tried to see again if I can ping from a computer connected to 192.168.0.1/24 LAN the router from 192.168.1.1 but it didn't worked. The server has tshark(console wireshark) installed and I found that while sending a ping from a computer connected to 192.168.0.1 router to 192.168.1.1 the 192.168.0.90(eth1) receives the ping but it doesn't forward it to the eth0 interface as the rule tells: iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT and don't now why this is happening. Questions: The iptables seem that don't work as I am expecting. Is there a need to add in the NAT table from iptables rules to redirect the traffic to the proper location, or is something else wrong with what I've done? I want to use tshark to view the traffic on the server because I think that is the best at doing this. Do you know something better that tshark to capture the traffic and maybe analyze it?

• SqlBulkCopy is slow, doesn't utilize full network speed

  - by Alex

  Hi, for that past couple of weeks I have been creating generic script that is able to copy databases. The goal is to be able to specify any database on some server and copy it to some other location, and it should only copy the specified content. The exact content to be copied over is specified in a configuration file. This script is going to be used on some 10 different databases and run weekly. And in the end we are copying only about 3%-20% of databases which are as large as 500GB. I have been using the SMO assemblies to achieve this. This is my first time working with SMO and it took a while to create generic way to copy the schema objects, filegroups ...etc. (Actually helped find some bad stored procs). Overall I have a working script which is lacking on performance (and at times times out) and was hoping you guys would be able to help. When executing the WriteToServer command to copy large amount of data ( 6GB) it reaches my timeout period of 1hr. Here is the core code for copying table data. The script is written in PowerShell. $query = ("SELECT * FROM $selectedTable " + $global:selectiveTables.Get_Item($selectedTable)).Trim() Write-LogOutput "Copying $selectedTable : '$query'" $cmd = New-Object Data.SqlClient.SqlCommand -argumentList $query, $source $cmd.CommandTimeout = 120; $bulkData = ([Data.SqlClient.SqlBulkCopy]$destination) $bulkData.DestinationTableName = $selectedTable; $bulkData.BulkCopyTimeout = $global:tableCopyDataTimeout # = 3600 $reader = $cmd.ExecuteReader(); $bulkData.WriteToServer($reader); # Takes forever here on large tables The source and target databases are located on different servers so I kept track of the network speed as well. The network utilization never went over 1% which was quite surprising to me. But when I just transfer some large files between the servers, the network utilization spikes up to 10%. I have tried setting the $bulkData.BatchSize to 5000 but nothing really changed. Increasing the BulkCopyTimeout to an even greater amount would only solve the timeout. I really would like to know why the network is not being used fully. Anyone else had this problem? Any suggestions on networking or bulk copy will be appreciated. And please let me know if you need more information. Thanks. UPDATE I have tweaked several options that increase the performance of SqlBulkCopy, such as setting the transaction logging to simple and providing a table lock to SqlBulkCopy instead of the default row lock. Also some tables are better optimized for certain batch sizes. Overall, the duration of the copy was decreased by some 15%. And what we will do is execute the copy of each database simultaneously on different servers. But I am still having a timeout issue when copying one of the databases. When copying one of the larger databases, there is a table for which I consistently get the following exception: System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. It is thrown about 16 after it starts copying the table which is no where near my BulkCopyTimeout. Even though I get the exception that table is fully copied in the end. Also, if I truncate that table and restart my process for that table only, the tables is copied over without any issues. But going through the process of copying that entire database fails always for that one table. I have tried executing the entire process and reseting the connection before copying that faulty table, but it still errored out. My SqlBulkCopy and Reader are closed after each table. Any suggestions as to what else could be causing the script to fail at the point each time?

• Oracle data warehouse design - fact table acting as a dimension?

  - by Elizabeth

  THANKS: Both answers here are very helpful, but I could only pick one. I really appreciate the advice! our datawarehouse will be used more for workflow reports than traditional analytical reports. Our users care about "current picture" far more than history. (though history matters, too.) We are a government entity that does not have costs or related calculations. Mostly just counts of people within given locations and with related history. We are using Oracle, and I have found distinct advantage in using the star join whenever possible and would like to rearchitect everything to as closely resemble the star schema as is reasonable for our business uses. Speed in this DW is vital, and a number of tests have already proven the star schema approach to me. Our "person" table is key - it contains over 4 million records and will be the most frequently used source in queries. It can be seen at the center of a star with multiple dimensions (like age, gender, affiliation, location, etc.). It is a very LONG table, particularly when I join it to the address and contact information. However, it is more like a dimension table when we start looking at history. For example, there are two different history tables that have a person key pointing to the person table. One has over 20 million records and the other has almost 50 million and grows daily. Is this table a fact table or a dimension table? Can one work as both? If so, is that going to be a big performance problem? Is it common to query more off of a dimension than a fact? What happens if a DIFFERENT fact table that uses the person table as a dimension is actually only 60,000 records (much smaller.). I think my problem is that our data and use of it does not fit with the commonly use examples of star schemas. CLARIFICATION: Some good thoughts have been added below, but perhaps I left too much out to really explain well. Here's some more info: We handle a voter database. We don't have any measures except voter counts by various groups: voter counts by party, by age, by location; voter counts by ballot type and election, by ballot status and election, etc. We do have a "voting history" log as well as an activity audit log (change of address, party, etc.). We have information on which voters are election workers and all that related information. I figure I'll get to the peripheral stuff later. For now I'm focusing on our two major "business processes": voter registration(which IS a voter.) and election turnout. In the first, voter is a fact. In the second, voter is a dimension, along with party, election, and type of ballot. (and in case anyone is worried - no we don't know HOW people vote. Just that they do. LOL ) I hope that clarifies things a bit.

• Part 7: EBS Modifications and Flagged Files in R12

  - by volker.eckardt(at)oracle.com

  Let me, based on my previous blog, explain the procedure of flagged files a bit better and facilitate the same with screenshots. Flagged files is a concept within the Oracle eBusiness Suite (EBS) release 12, where you flag a standard deployment file, let’s say a Forms file, a Package or a Java class file. When you run the patch analyse, the list of flagged files will be checked and in case one of these files gets patched, the analyse report will tell you. Note: This functionality is also available in release 11, here it is implemented and known as “applcust.txt”. You can flag as many files as you want, in whatever relationship they are with your customizations. In addition to the flag itself you can add a comment. You should use this comment to point to your customization reference (here XXAR_RPT_066 or XXAP_CUST_030). Consider the following two cases: You have created your own report, based on a standard report. In this case you will flag the report file itself, and the key views used. When a patch updates one of these files, you will be informed and can initiate a proper review and testing. (ex.: first line for ARXCTA.rdf) You have created an extensive personalization and because it is business critical you like to be informed if the page definition gets updated. In this case you register the PG.xml file as flagged file. (ex.: second line below for CreateExtBankAcctPG.xml) The menu path to register flagged files is the following: (R) System Administrator > (M) Oracle Applications Manager > Site Map > Maintenance > Register Flagged Files     Your DBA should now run the Patch Analyse every time he is going to apply a new patch. (R) System Administrator > (M) Oracle Applications Manager > Patch Wizard > Task “Recommend/Analyze Patches” The screenshot above shows the impact summary. For this blog entry the number “2” titled “Flagged Files Changed“ is in our focus. When you click the “2” you will get a similar screen like the first in this blog, showing you exactly the files which will get patched if you continue and apply this patch in this environment right now. Note: It is also shown that just 20% of all patch files will get applied. This situation might be different in case your environments are on a different patch level. For sure also the customization impact might then be different. The flagging step can be done directly in the Oracle Applications Manager.  Our developers are responsible for. To transport such a flag+comment we use a FNDLOAD script. It is suggested to put the flagged files data file directly into your CEMLI patch. Herewith the flagged files registration will be executed right at the same time when the patch gets applied. Process Steps: Developer: Builds CEMLI Reviews code and identifies key standard objects referenced Determines standard object files and flags them Creates FNDLOAD file and adds the same to the CEMLI patch DBA: Executes for every new Oracle standard patch the patch analyse in a representative environment Checks and retrieves the flagged files and comments Sends flagged file list back to development team for analyse / retest Developer: Analyses / Updates / Retests effected CEMLIs Prerequisite: The patch analyse has to be executed in an environment where flagged files have been registered. (If you run the patch analyse in a vanilla or outdated environment (compared to your PROD), the analyse will not be so helpful!) When to start with Flagged files? Start right now utilizing this feature. It is an invest to improve the production stability and fulfil your SLA!   Summary Flagged Files is a very helpful EBS R12 technique when analysing patches. Implement a procedure within your development process to maintain such flags. Let the DBA run the patch analyse in an environment with a similar patch and customization level as your current production.   Related Links: EBS Patching Procedures - Chapter 2-13 - Registered Flagged Files

• Troubleshooting Website problems within the local network

  - by HaydnWVN

  Have an external website which opens fine on some PC's, yet seems to time out (or symptoms of timing out, but never actually does) on others. Seems to only affect (some) of our newer HP Pro 3305 MT Workstations. All of which are running Win7 32bit SP1 with all updates. Older PC's (Win7 32bit SP1 & WinXP) are unaffected. Using Google Chrome & Firefox makes no difference. Opening the website in IE9 Compatibility Mode has exactly the same symptoms. All PC's are on the same local network (Workgroup) using the same DNS server & gateway (inhouse) on the same internet connection, on the same subnet. There is no proxy server, no content filtering, no load balancing etc etc. Only group policy in effect (locally) is for Update scheduling. Local firewalls are all the same (Kaspersky WP4) and our external facing firewall has no IP specific settings. I have no control over the external website, traceroute shows the same destination on all PC's. It is a fairly popular website in our industry (Horticulture) and i'm not aware of any other people (even other sites within our sister companies) with the same problem. Update: Used Fiddler2 to monitor the HTTP request, seems its not getting fulfilled for some reason?!

• How to connect FreeBSD Jail to network

  - by jgtumusiime

  So recently I successfully installed and configured a freebsd jail and I would like to install software within my jail but I cannot connect to the network. I'm trying to setup an apache+php+mysql installation within the jail and have the webserver accessible by users. Here is my rc.conf for the jail. ... jail_enable="YES" # Set to NO to disable starting of any jails jail_list="mambo2" # Space separated list of names of jails jail_mambo2_rootdir="/usr/jails/j01" # jail's root directory jail_mambo2_hostname="mambo2.ug" # jail's hostname jail_mambo2_ip="192.168.100.174" # jail's IP address jail_mambo2_devfs_enable="YES" # mount devfs in the jail jail_mambo2_devfs_ruleset="mambo2_ruleset" # devfs ruleset to apply to jail here is my jail ifconfig output mambo2# ifconfig rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=8<VLAN_MTU> ether 00:c1:28:00:48:db media: Ethernet autoselect (100baseTX <full-duplex>) status: active plip0: flags=108810<POINTOPOINT,SIMPLEX,MULTICAST,NEEDSGIANT> metric 0 mtu 1500 lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384 mambo2# It does not show the IP address I configured within /etc/rc.conf.

• Poor home office network performance and cannot figure out where the issue is

  - by Jeff Willener

  This is the most bizarre issue. I have worked with small to mid size networks for quite a long time and can say I'm comfortable connecting hardware. Where you will start to lose me is with managed switches and firewalls. To start, let me describe my network (sigh, shouldn't but I MUST solve this). 1) Comcast Cable Internet 2) Motorola SURFboard eXtreme Cable Modem. a) Model: SB6120 b) DOCSIS 3.0 and 2.0 support c) IPv4 and IPv6 support 3-A) Cisco Small Business RV220W Wireless N Firewall a) Latest firmware b) Model: RV220W-A-K9-NA c) WAN Port to Modem (2) d) vlan 1: work e) vlan 2: everything else. 3-B) D-Link DIR-615 Draft 802.11 N Wireless Router a) Latest firmware b) WAN Port to Modem (2) 4) Servers connected directly to firewall a) If firewall 3-A, then vlan 1 b) CAT5e patch cables c) Dell PowerEdge 1400SC w/ 10/100 integrated NIC (Domain Controller, DNS, former DHCP) d) Dell PowerEdge 400SC w/ 10/100/1000 integrated NIC (VMWare Server) 4) Linksys EZXS88W unmanaged Workgroup 10/100 Switch a) If firewall 3-A, then vlan 2 b) 25' CAT5e patch cable to firewall (3-A or 3-B) c) Connects xBox 360, Blu-Ray player, PC at TV 5) Office equipment connected directly to firewall a) If firewall 3-A, then vlan 1 b) ~80' CAT6 or CAT5e patch cable to firewall (3-A or 3-B) c) Connects 1) Dell Latitude laptop 10/100/1000 2) Dell Inspiron laptop 10/100 3) Dell Workstation 10/100/1000 (Pristine host, VMWare Workstation 7.x with many bridged VM's) 4) Brother Laser Printer 10/100 5) Epson All-In-One Workforce 310 10/100 5-A) NetGear FS116 unmanaged 10/100 switch a) I've had this switch for a long time and never had issues. 5-B) NetGear GS108 unmanaged 10/100/1000 switch a) Bought new for this issue and returned. 5-C) Linksys SE2500 unmanaged 10/100/1000 switch a) Bought new for this issue and returned. 5-D) TP-Link TL-SG10008D unmanaged 10/100/1000 a) Bought new for this issue and still have. 6) VLan 1 Wireless Connections (on same subnet if 3-B) a) Any of those at 5c b) HP Laptop 7) VLan 2 Wireless Connection (on same subnet if 3-B) a) IPad, IPod b) Compaq Laptop c) Epson Wireless Printer Shew, without hosting a diagram I hope that paints a good picture. The Issue The breakdown here is at item 5. No matter what I do I cannot have a switch at 5 and have to run everything wireless regardless of router. Issues related to using a switch (point 5 above) SpeedTest is good. Poor throughput to other devices if can communicate at all. Usually cannot ping other devices even on the same switch although, when able, ping times are good. Eventual lose of connectivity and can "sometimes" be restored by unplugging everything for several days, not minutes or hours but we're talking a week if at all. Directly connect to computer gives good internet connection however throughput to other devices connected to firewall is at best horrible. Yet printing doesn't seem to be an issue as long as they are connected via wireless. I have to force the RV220W to 1000Mb on the respective port if using a Gig Switch Issues related to using wireless in place of a switch (point 5 above) Poor throughput to other devices if can communicate. SpeedTest is good. Bottom line Internet speeds are awesome. By the way, Comcast went WAY above and beyond to make sure it was not them. They rewired EVERYTHING which did solve internet drops. Computer to computer connections are garbage Cannot get switch at 5 to work, yet other at 4 has never had an issue. Direct connection, bypass switch, is good for DHCP and internet. DNS must be on server, not firewall. Cisco insists its my switches but as you can see I have used four and two different cables with the same result. My gut feeling is something is happening with routing. But I'm not smart enough to know that answer. I run a lot of VM's at 5-c-3, could that cause it? What's different compared to my previous house is I have introduced Gigabit hardware (firewall/switches/computers). Some of my computers might have IPv6 turned on if I haven't turned it off already. I'm truly at a loss and hope anyone has some crazy idea how to solve this. Bottom line, I need a switch in my office behind the firewall. I've changed everything. The real crux is I will find a working solution and, again, after days it will stop working. So this means I cannot isolate if its a computer since I have to use them. Oh and a solution is not throwing more money at this. I'm well into $1k already. Yah, lame.

• Network traffic is not being forwarded from a VM to the network using a bridged interface with Xen + libvirt

  - by foob

  I'm having trouble getting network access from a VM that I'm running using Xen and libvirt. I've been trying different things and reading similar posts online for a couple of days but I'm really stuck at this point. If anybody could offer some insight it would be much appreciated. I have a VM that I'm running on a host with a bridge set up as br0 and an interface eth0 on a 192.168.60.0/24 subnet. The networking portion of the libvirt configuration xml is: <interface type='bridge'> <mac address='ff:a0:d1:e5:07:de'/> <source bridge='br0'/> <script path='/etc/xen/scripts/vif-bridge'/> <model type='virtio' /> </interface> When I start the VM a vif6.0 interface is created on the host and the ifconfig output is: br0 Link encap:Ethernet HWaddr 00:A0:D1:C3:07:DE inet addr:192.168.60.33 Bcast:192.168.60.255 Mask:255.255.255.0 inet6 addr: fe80::2a0:d1ff:fee5:7de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:13 errors:0 dropped:0 overruns:0 frame:0 TX packets:40 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3570 (3.4 KiB) TX bytes:3508 (3.4 KiB) eth0 Link encap:Ethernet HWaddr 00:A0:D1:C3:07:DE inet6 addr: fe80::2a0:d1ff:fee5:7de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:492 (492.0 b) Interrupt:19 Memory:fe8f0000-fe900000 vif6.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:80 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:6660 (6.5 KiB) TX bytes:468 (468.0 b) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) The 'brctl show' output seems to show the bridge being configured correctly: br0 8000.00a0d1e507de no eth0 vif6.0 The ifcfg-eth0 contents in the VM are: DEVICE=eth0 BOOTPROTO=static HWADDR=FF:A0:D1:E5:07:DE IPADDR=192.168.60.133 NETMASK=255.255.255.0 ONBOOT=yes and the output of ifconfig in the VM look like what I would expect: eth0 Link encap:Ethernet HWaddr FF:A0:D1:E5:07:DE inet addr:192.168.60.133 Bcast:192.168.60.255 Mask:255.255.255.0 inet6 addr: fe80::fda0:d1ff:fee5:7de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:80 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:468 (468.0 b) TX bytes:7780 (7.5 KiB) but when I try to ssh or ping another computer I get 'no route to host.' Using tcpdump on the host system I tried to see if I could narrow down where the problem is: # tcpdump -vv -i vif6.0 tcpdump: WARNING: vif6.0: no IPv4 address assigned tcpdump: listening on vif6.0, link-type EN10MB (Ethernet), capture size 96 bytes 14:49:40.833997 arp who-has 192.168.60.35 tell 192.168.60.133 14:49:41.833314 arp who-has 192.168.60.35 tell 192.168.60.133 14:49:42.833309 arp who-has 192.168.60.35 tell 192.168.60.133 So the VM is sending out out an arp who-has packet when I try to ssh to 192.168.60.35. I think that this means the setup within the VM is ok and that this is an issue on the host system. If I run tcpdump with the interface of br0 then I don't see these arp packets. My thought here is that the packets are being blocked before going on to the bridge somehow. I tried adding an iptables rule to resolve this: -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT but it didn't work. I also tried the following: /sbin/sysctl -w net.bridge.bridge-nf-call-ip6tables=0 /sbin/sysctl -w net.bridge.bridge-nf-call-iptables=0 /sbin/sysctl -w net.bridge.bridge-nf-call-arptables=0 /sbin/sysctl -w net.ipv4.ip_forward=1 which had no impact. Is it obvious to somebody who has more experience than me what I'm missing here? Should vif6.0 have the same MAC address is eth0 in the vm? Do I need more rules in my iptables? Thanks for any help!

• Linux/Apache performance very slow even on local network

  - by klausch

  I have an Ubuntu server machine running Apache and MYSQL. System and version info is as follows: Linux kernel 3.0.0.-12 Apache/2.2.20 MySQL Ver 14.14.Distrib 5.1.58 I am running a few websites on this server, some HTML only, some PHP/MySQL. THe [problem is that response time is very slow, both on static as well as the dynamic sites. Sometimes it takes more than 10 seconds before a response is given, this makes the sites very slow and almost unusable. The problem occurs even when requesting from the local network. I have added the involved subdomains to my /etc/hosts file, and abolve all the problem is not solved by using IP numbers instead of URL's. So there is no DNS lookup issue. I have modified the log format by showing the response times and sometimes a files takes 12 seconds to be served, see the jquery~.js file in the example screenshot. I have no explanation for this extremely long response time, but is is not even the only issue here, some other files takes a long time to be served too, but do not show a long response time in the log file. So probably different tissues are involved here. I cannot find a solution until now, any suggestions??? THanx in advance, Klaas link to screenshot picture from access logfile Some extra configuration info: apache2.conf (comment is removed) LockFile ${APACHE_LOCK_DIR}/accept.lock PidFile ${APACHE_PID_FILE} Timeout 300 KeepAlive On MaxKeepAliveRequests 100 KeepAliveTimeout 5 <IfModule mpm_prefork_module> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_worker_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> <IfModule mpm_event_module> StartServers 2 MinSpareThreads 25 MaxSpareThreads 75 ThreadLimit 64 ThreadsPerChild 25 MaxClients 150 MaxRequestsPerChild 0 </IfModule> User ${APACHE_RUN_USER} Group ${APACHE_RUN_GROUP} AccessFileName .htaccess <Files ~ "^\.ht"> Order allow,deny Deny from all Satisfy all </Files> DefaultType text/plain HostnameLookups Off ErrorLog ${APACHE_LOG_DIR}/error.log LogLevel warn Include mods-enabled/*.load Include mods-enabled/*.conf Include httpd.conf Include ports.conf LogFormat "%v:%p %h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\"" vhost_combined LogFormat "%h %l %u %t \"%r\" %>s %O \"%{Referer}i\" \"%{User-Agent}i\" %T/%D" combined LogFormat "%h %l %u %t \"%r\" %>s %O" common LogFormat "%{Referer}i -> %U" referer LogFormat "%{User-agent}i" agent Include conf.d/ Include sites-enabled/ And the virtual hostfile for one of the slow sites, in fact it is pretty straightforward... <VirtualHost *:80> ServerAdmin [email protected] ServerSignature EMail ServerName toenjoy.drsklaus.nl DocumentRoot /var/www/toenjoy.drsklaus.nl <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/toenjoy.drsklaus.nl/> Options Indexes FollowSymLinks MultiViews AllowOverride AuthConfig AuthType Basic AuthName "To Enjoy" AuthUserFile /etc/.htpasswd Require user petraaa Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

I have runned top and it does not appear to be a CPU issue. I have the impression that the spawning of a apache thread could maybe be the bottleneck but it is just a suggestion. Maybe this gives some extra information! EDIT: The problem seemed to be gone for some time but occurs again! And not only with Apache, also connecting using SSH takes a tremendous time, sometimes it takes up to 15 seconds before the keyphrase is asked for. Also scp works very slowly. The behavious is really unpredoctable and makes the server very hard to use. Any ideas...?

• Weblogic domain scale up using EM Grid Control 11gR1

  - by dmitry.nefedkin(at)oracle.com

  As you know a weblogic domain consists of set of servers running independently or in a cluster mode, sharing the distributed resources. And in most environments weblogic  cluster consists of multiple managed servers running simultaneously and working together to provide increased scalability and reliability.  These servers can run on the same machine, or be located on different machines.  It's a common task to increase a cluster's capacity by adding new machines to the cluster to host the new server instances.  You can do it by manually installing weblogic binaries to the new host and use pack/unpack commands to add a managed server to this new host.  But with Enterprise Manager Grid Control 11gR1 (EMGC) there is  another way - Fusion Middleware Domain Scale Up  procedure. I'm going to show you how it works.Here is a picture of  my medrec_oradb weblogic domain, what is registered in EMGC. It contains an admin server and a cluster MedRecCluster with  the single managed server MS1. Both admin and managed servers are on the same host oel46-vmware, it's a virtual machine with OEL 4.6 that runs inside our Oracle VM infrastructure.  And here are the application deployments, note that couple of applications are deployed to the cluster.First of all I have to prepare a new machine that will host new managed sever of my cluster. I created new VM with OEL 5.4 using the corresponding Oracle VM template available in Oracle E-Delivery site for Oracle Linux and Oracle VM and named it wls1032. Next step is to install Oracle EM Grid Control 11gR1 Agent to this new host.  You can download it from the OTN page and install it manually,  or you can use Agent Installation Deployment procedure available in EMGC  (Deployments->Agent Installation->Install Agent). Anyway, when you agent is up and running on the new machine, you will see it in EMGC Console in the Targets->Hosts subtab.Now we are ready to scale up our weblogic domain. Click the Deployments tab in Oracle Enterprise Manager Grid Control, and then click Deployment Procedure. Select a Fusion Middleware Domain Scale Up procedure from the list, and click Schedule Deployment. The first page of the FMW Domain Scale Up Wizard is displayed and you can proceed with the deployment process.Select the domain from list, enter the working directory on the admin server host, and also fill the weblogic credentials for the administration server console and the OS credentials for the  admin server host.  Click Next button.  The next step allows you to configure you domain, to add a new manager server to the cluster you should select the cluster in the tree and click Add Server button. Select the newly added server in a tree, choose the target host and  enter the configuration details of your managed server. You can also add new machine and node manager details.  Please note that you cannot change the values in  Domain Location and Fusion Middleware Home fields, so these locations on the target host will be the same as for the admin server host.   Working directory on the target host should have enough free space to store FMW home binaries and domain configuration files.  In my experience the working directories should have at least 3 Gb of free space.  The last thing you should fill is the OS credentials for the target host. The next steps allows you to schedule the execution of the procedure, it is started immediately in my example. The last step is just a review the configuration for the domain scale up. Click Submit to launch the process. You can track the status of the procedure execution by selecting Deployments->Deployment Procedures->Procedure Completion Status in the EMGC Console.As you can see in the picture below, the procedure consists of the many steps, and I'm going to share my experience about the issues that I had at some of the steps.

• Qt Sockets and Endianness

  - by cake

  Hello I'm writing a program that uses QUdpSocket for transmiting data over the network. This is my first socket program, and I've come across an interesting problem called Endianness. My actual question in, do I have to worry about Endianness when I'm using QNetwork as my sockets library? If I do have to worry, what do I have to do to properly avoid Endianness problems? Thanks in advance.

• Solaris: Programmatic interface to ifconfig?

  - by David Citron

  I'm looking for a programmatic interface to the Solaris ifconfig(1M) command. Apparently Linux has the getifaddrs(3) command, but as far as I can tell this has not been ported to Solaris. Short of attempting to use the code at the link above, is there any way to determine ifconfig(1M)-type data (network interface presence, state, etc.) without forking the system command and parsing the output?

• Implement Semi-Round-Robin file which can be expanded and saved on demand

  - by ircmaxell

  Ok, that title is going to be a little bit confusing. Let me try to explain it a little bit better. I am building a logging program. The program will have 3 main states: Write to a round-robin buffer file, keeping only the last 10 minutes of data. Write to a buffer file, ignoring the time (record all data). Rename entire buffer file, and start a new one with the past 10 minutes of data (and change state to 1). Now, the use case is this. I have been experiencing some network bottlenecks from time to time in our network. So I want to build a system to record TCP traffic when it detects the bottleneck (detection via Nagios). However by the time it detects the bottlenecking, most of the useful data has already been transmitted. So, what I'd like is to have a deamon that runs something like dumpcap all the time. In normal mode, it'll only keep the past 10 minutes of data (Since there's no point in keeping a boat load of data if it's not needed). But when Nagios alerts, I will send a signal in the deamon to store everything. Then, when Naigos recovers it will send another signal to stop storing and flush the buffer to a save file. Now, the problem is that I can't see how to cleanly store a rotating 10 minutes of data. I could store a new file every 10 minutes and delete the old ones if in mode 1. But that seems a bit dirty to me (especially when it comes to figuring out when the alert happened in the file). Ideally, the file that was saved should be such that the alert is always at the 10:00 mark in the file. While that is possible with new files every 10 minutes, it seems like a bit dirty to "repair" the files to that point. Any ideas? Should I just do a rotating file system and combine them into 1 at the end (doing quite a bit of post-processing)? Is there a way to implement the semi-round-robin file cleanly so that there is no need for any post-processing? Thanks Oh, and the language doesn't matter as much at this stage (I'm leaning towards Python, but have no objection to any other language. It's less of an issue than the overall design)...

• ANN for decompiler?

  - by Rhythmic Algorithm

  Has there ever been any attempts at utilizing artificial neural networks in decompilation? It would be nice if it was possible to provide the trimmed semantics of source along with the code in to a neural network so it could learn the connection between the two. I assume this would likely lose it's effectiveness when there is optimizations and maybe work better for high level languages too but I'm interested in hearing any attempts anyone has had at this.
