• Vista stuck at "Shutting down..." screen. Any way to get verbose logging?

  - by CapBBeard

  Hi all, My home machine has been running fine for about 3 years, no problems at all. Within the last couple of weeks it's had real trouble trying to shut down. It'll get so far and then just sit there at the "Shutting down..." screen for hours. I've left it overnight, I've tried in safe mode, all to no avail. These days, I just wait for the disk activity to finish up and then hold the power button to turn it off. Feels dirty as, especially because there's a RAID involved! The hardware itself is in pretty good shape and of decent spec; Core 2 Quad, 4GB RAM, 1TB RAID 1+0, so it's not quite like a 7 year old PC coming to end of life! In the last month, hardware hasn't changed except for a new monitor. Admittedly I haven't tried unplugging the monitor but I've never heard of that preventing a shutdown. I might give it a whirl later I guess, as a last resort. I've uninstalled old apps, done updates, checked the event log, looked in device manager, uninstalled all non-present devices, disabled various non-critical devices (imaging, audio etc), unplugged peripherals, stopped non-essential services, unplugged the network, disabled the network adapter entirely, ran chkdsk, verified my RAID, the list goes on. But not a single lead. I'm pretty stumped. It could be hardware, but I have no other evidence to suggest so; when the PC is running, it runs fine. Temperatures are good, gaming is smooth as always, disk performance is fine. Event log even makes it look like the shutdown was completed (gets to the point where the event log service stops). In fact, the PC doesn't appear to realise that I cut the power to it. So my question is, does anyone know if there is a way I can get some verbose output (or a log) from shutdown to give me some idea of what is causing the issue? I'm guessing it's stuck unloading some app/driver but it would be good to get some specifics! Unless anyone has any other ideas? I suspect a reinstall would resolve the issue, however I'm looking to get a new PC built in the next month or so, and the reinstall is going to be quite a big job so I'd rather just wait until then if it comes to that. Would still be nice to get this sorted in the mean time though. Cheers!

• nginx + Jetty - thousands of connections stuck in LAST_ACK

  - by virulence

  I have a FreeBSD machine with jails -- two in particular, one that runs nginx and another that runs a Java program that accepts requests via Jetty (embedded mode) Jetty receives upwards of 500 requests/sec constantly and there has been an issue lately where I will constantly have over 60,000 connections in the LAST_ACK state between nginx and jetty. Distribution of all connections (includes some other services, particularly php-fpm) root@host:/root # netstat -an > conns.txt root@host:/root # cat conns.txt | awk '{print $6}' | sort | uniq -c | sort -n 18 LISTEN 112 CLOSING 485 ESTABLISHED 650 FIN_WAIT_2 1425 FIN_WAIT_1 3301 TIME_WAIT 64215 LAST_ACK Distribution of nginx - jetty connections root@host:/root # cat conns.txt | grep '10.10.1.57' | awk '{print $6}' | sort | uniq -c | sort -n 1 3 CLOSE_WAIT 3 LISTEN 18 FIN_WAIT_2 125 ESTABLISHED 64193 LAST_ACK I'd prefer every request to fully close the connection. Clients requests are about 10 minutes apart from each other so connections must be closed. Some of the connections, tcp4 0 0 10.10.1.50.46809 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46805 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46797 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46794 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46790 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46789 10.10.1.57.9050 LAST_ACK tcp4 0 0 10.10.1.50.46771 10.10.1.57.9050 LAST_ACK etc.. On Jetty's end I've set maxIdleTime to 2000 -- before this all connections were in ESTABLISHED but they are now LAST_ACK On Jetty's end I've set Connection: close (i.e response.setHeader(HttpHeaders.CONNECTION, HttpHeaderValues.CLOSE);) Jetty never reports a lot of open connections -- always very few. PF/IPFW is not currently being used nginx - reset_timedout_connection is on I cannot figure out how to get nginx or jetty to forcibly close the connection, is this simply something that needs to be fixed in Jetty so that it fully closes the socket after the request finishes? Thanks a lot in advance EDIT: forgot my nginx config for the proxy setup- proxy_pass http://10.10.1.57:9050; proxy_set_header HTTP_X_GEOIP $http_x_geoip; proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header Connection ""; proxy_http_version 1.1; EDIT2: Forcing Jetty to close the connection via request.getConnection().getEndPoint().close() does nothing -- it's obvious the connection IS being closed (as it's in LAST_ACK) but why isn't it getting past this? Is Nginx keeping the connection open to the backend for some reason?

• Automating silent software deployments on Solaris 10

  - by datSilencer

  Hello everyone. Essentially, the question I'd like to ask is related to the automation of software package deployments on Solaris 10. Specifically, I have a set of software components in tar files that run as daemon processes after being extracted and configured in the host environment. Pretty much like any server side software package out there, I need to ensure that a list of prerequisites are met before extracting and running the software. For example: Checking that certain users exists, and they are associated with one or many user groups. If not, then create them and their group associations. Checking that target application folders exist and if not, then create them with preconfigured path values defined when the package was assembled. Checking that such folders have the appropriate access control level and ownership for a certain user. If not, then set them. Checking that a set of environment variables are defined in /etc/profile, pointed to predefined path locations, added to the general $PATH environment variable, and finally exported into the user's environment. Other files include /etc/services and /etc/system. Obviously, doing this for many boxes (the goal in question) by hand can be slow and error prone. I believe a better alternative is to somehow automate this process. So far I have thought about the following options, and discarded them for one reason or another. 1) Traditional shell scripts. I've only troubleshooted these before, and I don't really have much experience with them. These would be my last resort. 2) Python scripts using the pexpect library for analyzing system command output. This was my initial choice since the target Solaris environments have it installed. However, I want to make sure that I'm not reinveting the wheel again :P. 3) Ant or Gradle scripts. They may be an option since the boxes also have java 1.5 enabled, and the fileset abstractions can be very useful. However, they may fall short when dealing with user and folder permissions checking/setting. It seems obvious to me that I'm not the first person in this situation, but I don't seem to find a utility framework geared towards this purpose. Please let me know if there's a better way to accomplish this. I thank you for your time and help.

• What the best way to achieve RPO of zero and lowest possible RTO (less than 15 minutes) with SQL 2008 R2?

  - by Adrian Hope-Bailie

  We are running a payments (EFT transaction processing) application which is processing high volumes of transactions 24/7 and are currently investigating a better way of doing DB replication to our disaster recovery site. Our current and previous strategies have included using both DoubleTake and Redgate to replicate data to a warm stand-by. DoubleTake is the supported solution from the payments software vendor however their (DoubleTake's) support in South Africa is very poor. We had a few issues and simply couldn't ever resolve them so we had to give up on DoubleTake. We have been using Redgate to manually read the data from the primary site (via queries) and write to the DR site but this is: A bad solution Getting the software vendor hot and bothered whenever we have support issues as it has a tendency to interfere with the payment application which is very DB intensive. We recently upgraded the whole system to run on SQL 2008 R2 Enterprise which means we should probably be looking at using some of the built-in replication features. The server has 2 fairly large databases with a mixture of tables containing highly volatile transactional data and pretty static configuration data. Replication would be done over a WAN link to a separate physical site and needs to achieve the following objectives. RPO: Zero loss - This is transactional data with financial impact so we can't lose anything. RTO: Tending to zero - The business depends on our ability to process transactions every minute we are down we are losing money I have looked at a few of the other questions/answers but none meet our case exactly: SQL Server 2008 failover strategy - Log shipping or replication? How to achieve the following RTO & RPO with logshipping only using SQL Server? What is the best of two approaches to achieve DB Replication? My current thinking is that we should use mirroring but I am concerned that for RPO:0 we will need to do delayed commits and this could impact the performance of the primary DB which is not an option. Our current DR process is to: Stop incoming traffic to the primary site and allow all in-flight transaction to complete. Allow the replication to DR to complete. Change network routing to route to DR site. Start all applications and services on the secondary site (Ideally we can change this to a warmer stand-by whereby the applications are already running but not processing any transactions). In other words the DR database needs to, as quickly as possible, catch up with primary and be ready for processing as the new primary. We would then need to be able to reverse this when we are ready to switch back. Is there a better option than mirroring (should we be doing log-shipping too) and can anyone suggest other considerations that we should keep in mind?

• Ping Unknown Host on CentOS at EC2

  - by organicveggie

  Weird problem. We have a collection of servers running CentOS 5 on EC2. The setup includes two DNS servers and two LDAP servers. DNS has a CNAME pointing at the primary LDAP server. One machine (and only one machine) is giving me problems. I can ssh into the server using LDAP authentication. But once I'm on the machine, ping won't resolve the LDAP host even though DNS seems to work fine. Here's ping: $ ping ldap.mycompany.ec2 ping: unknown host ldap.mycompany.ec2 Here's the output of dig: $ dig ldap.mycompany.ec2 ; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_5.3 <<>> ldap.studyblue.ec2 ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 2893 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;ldap.mycompany.ec2.

• How to configure DD-WRT routing table when creating an isolated network segment for PCI C VT compliance

  - by tetranz

  I'm the volunteer support and system admin person at a small private school. We need to setup a PCI compliant Windows PC as a virtual terminal for credit card processing. I've read questionnaire SAQ C-VT and, to quote, this computer needs to be accessed: "via a computer that is isolated in a single location, and is not connected to other locations or systems within your environment (this can be achieved via a firewall or network segmentation to isolate the computer from other systems)" Our setup is as follows: DSL modem from ISP is setup to be a "transparent pipe" with no extra services. That goes into the WAN port of Linksys WRT54-GL running a DD-WRT. The LAN is 192.168.1.x. There are a couple of other WRT54-GL / DD-WRT devices. One is used as a wireless AP and another is a client bridge. To isolate the VT (virtual terminal) machine, I have another DD-WRT device. Its WAN is connected to a port on the 192.168.1.x LAN. The virtual terminal machine is connected to its LAN which is at 192.168.10.x. The SPI Firewall etc is turned on. It's basically the default DD-WRT gateway setup where the "ISP" is our own LAN. That's working. All incoming traffic to the VT machine is blocked, including from our own LAN. The VT can access the internet BUT, and here's the problem, it can also ping any of the computers on the 192.168.1.x LAN. I think I need to stop that. I'm guessing that I could do something with the Static Routing table in the VT machine's DD-WRT device. I need to route anything going to 192.168.1.x other than the gateway which is 192.168.1.1 to 0.0.0.0 or something like that. That's where I'm stuck at the end of my knowledge. Or ... do I need to get yet another DD-WRT so the network is "balanced". Maybe I need to have the internet from the DSL going into a DD-WRT which has only two devices on its LAN i.e., two other DD-WRTs, one for the main LAN and one for the VT. I think that would do but I'd like to avoid the extra cost and complexity if I don't need it. Thanks

• How to Configure Source NAT (Private IP => Public IP Outbound)

  - by DavidScherer

  I'm running VMWare ESXi Free and have Zentyal SBS 3.2 running as a Gateway. I have 5 Public IPS (CIDR/29, let's call them 69.1.1.1 - 69.1.1.5) and currently Zentyal is bound to 69.1.1.1 as the Gateway, with the other 4 Public IPs set as Virtual Interfaces in Zentyal (wan2-wan5) I have machines sitting on the Private Network (10.34.251.x) that, when going Outbound (to Google for instance) should be seen by the Internet as an IP other than the Gateway (69.1.1.1), this is because our machines need to be able to communicate with 3rd party APIs that expect these requests to come from a specific IP. From what I could find, SNAT (Source NAT) in Zentyal is used to achieve this, but I'm not sure how to configure it and cannot find a specific piece of Documentation for it at Zentyal. I've tried setting this up a couple different ways, with no results and at this point I have no idea if I'm going about this completely wrong, or my lack of experience with networking and the associated terminology is preventing me from placing the correct values in the correct fields. I get the following form to set up "SNAT" rules in Zentyal: Perhaps someone can offer some guidance and definitions for the fields above? SNAT Address Is this the Public IP I want to masquerade? Outgoing Interface Should this by my External NIC (one connected to Public 'Net), or is it the "Private" interface? It sounds as though this should be the External interface as I want the traffic from the internal network sent Out over this Interface (using a different IP than normal, anyway) Source Is the the Source on the internal network (one of the private IPs?), a public IP I want to masquerade as, or something else entirely? Destination Is this a place on the Internet (eg, "Only do this for the Site Google.com"/IP) or am I allowing myself to become confused again? Service I'm assuming this allows me to restrict which services this rule will apply to, but is it for a service on the internal network or a service being accessed on the external network? If I can offer any further details or information to make what I'm trying to do more clear, I will happily do so. Honestly any kind of help here would be very appreciated. I'm not a NetOps or anything even close, I spend most of my day writing code and my entire "team" at this company consists of "me, myself, and I" so while I try to broaden my KB at every possible opportunity, I can only learn so much, so fast and I feel like with networking especially there's just so much, coupled with a learning curve for each solution that likes to (from my limited perspective) use slightly different terminology that what I'm used to (and I don't exactly have the necessary experience to cross reference this stuff with the stuff I already know in context).

• Well....a ghost lives in my server...

  - by tsgiannis

  Hello to every body and greetings from Greece I have a rather unusual situation and i am running out of ideas. I have this old server (IBM x205 - P4 2.4Ghz,3xSCSI 36gb) and i was about a year ago i decided to use it as an additional domain controller,fax & file server...for this task i had a Delock 70154 SATA card along with 2x320 SATA II HDDs Everything was going super smoothly until about 3 weeks ago. I was on a trip and i was informermed when i got back that the server was found frozen...well i considered it was a glitch since a simple powerdown power up fixed everything.Again 2 weeks ago another freeze situation....it got suspicious but again power down power up everything was running.... Last again it frozen and when i power it up it came with a message that the Domain services could not start due to NTDS corruption....booting in safe mode revealed that there was an issue with the SATA Raid (degraded). After a lot of searching i degraded the server...cleaned Active Directory and pulled both HDDs out (one of these was really BAD ) and recovered my files (i had some problems with ho Delock handles the redudant HDD). Right now my server is vanilla simple...with only what the factory installed and here is where the fun begins. Everyday when i arrive at the office i find this particular machine dead..and i mean total dead...just a black screen and nothing else...the cpu fan is working ,the psu is working .keyboard and mouse are dead(they also lock my kvm) ...network is dead.... the machine is DEAD. I power it down forcilly ...i power it up and for the 8 hours i am in the office it works,either idling or running some kind of diagnostic...when i leave the office after some time..it maybe half an hour ...it maybe 4 hours the machine dies...at least this is the information the event log shows (" the previous shutdown at xx:xx:xx was unexpected) Well i must admit i am runnig out of ideas.... I have tried Memtest....nothing Passmark burn in test.....nothing Carefull study of the event log.....nothing Set Instead of restart..BSOD....nothing Power sceheme to sleep...all set to never. i know there are a lot of other tools that heavily stress a machine like occt but .... the machine is old...today i will give them a try nevertheless ..... One idea is to reformat it...but ... i really like to find what is causing this because i could get to a situation that everything is working for a while and kaboom...one day again is dying.. I really need a helping hand and every opinion / idea is well welcomed.... iknow the obvious solution is to never leave the office but....i have a life...sory server...:) P.S this situation with the machine dying some time after is going on for about one week...everyday i would set either the RAID to rebuild....or to copy/recover files and while everythig was working

• Can't find windows 2000 domain after PDC Change

  - by Mark A Kruger

  This is a windows 2000 domain issue. I had an old win2000 PDC that was beginning to fail. So, trying to be pre-emptive, I installed a new BDC, then "demoted" the old PDC and took it off the network. Now it appears that no member server can "find" the domain anymore. No logins work (for services or a RDP or anything). What I've tried (based on googling): Verified sysvol is shared on all servers. Used nslookup to verify that DC's are being found. netdiag /fix meta data cleanup routines. verified no firewall issues (port 389 etc) seizing all roles to new PDC (I did that as part of the original promotion). LMHOST file and Netbios settings. At the moment it seems like I can get the DC's returned but cannot contact them. I'm at a loss. My latest attempt was to remove a member server from the domain and try to "re-add" it. When I do that I get this message: The query was for the SRV record for _ldap._tcp.dc._msdcs.cfwebtools.com The following domain controllers were identified by the query: db-dev1.cfwebtools.com file-prod1.cfwebtools.com cfwt-pdc2.cfwebtools.com However no domain controllers could be contacted. It then goes on to ask if I've checked my A record and made sure they are running. Is there a way to force this domain to be seen? I also shared sysvol (or double checked it) and restarted the dfsr service. More information. I got looking at sysvol and found it was not shared on 2 of these servers. Only one of them (db-dev1) has a "good" or at least "populated" sys vol store. So I tried doing a "d2" recovery of my PDC against that good sysvol. But it never synchs - or at least it does not seem to synch. I'm guessing if I could get sysvol and netlogin to kick in and replicate that would fix my issue. I think these DC's aren't responding because they are waiting for replication which is broken somehow. Would taking down all the DC's except for db-dev1 fix the issue - at least temporarily? I know I can't just copy the sysvol stuff over to the other 2 can I?

• Managing hosts and iptables in scalable architecture

  - by hakunin

  Let's say I have a load balancer in front of 3 app servers. Let's say I also have these services available at certain IPs: Postgres server Redis server ElasticSearch server Memcached server 1 Memcached server 2 Memcached server 3 So that's 6 nodes at 6 different IP addresses. Naturally, every one of my 3 app servers needs to talk to these 6 servers above. Then, to make it a bit funkier, I also have 3 worker servers. And each worker also talks to the above 6 servers, but thankfully workers and apps never need to talk to each other. Now's the kicker. Everything is on Digital Ocean VPS. What that means is: you have no private network, no private IPs. You only have separate, random IP address on each machine. You can't mask them or anything. So in order to build a secure environment I would have to configure some iptables. For example: Open app servers be accessed by load balancer server Open redis, ES, PG, and each memcached servers to be accessed by each app's IP and each worker's IP This means that every time I add an app or worker I have to also reconfigure iptables in those above 6 servers to welcome the new app or worker. Is there a way to simplify this type of setup? I was thinking — what if there was a gateway machine between apps/workers and the above 6 machines. This way all the interaction would always happen via the gateway server, and when I add a new app or worker I wouldn't need to teach the 6 servers to let it in. If I went this route, then I'd hope a small 512mb server could handle that perhaps, and there wouldn't be almost any overhead. Or would there? Please help with best way to handle this situation. I would appreciate an answer as concrete as possible. I don't think this is too specific, because this general architecture is very common, and Digital Ocean is becoming increasingly popular. A concrete solution here would be much appreciated by many.

• JBoss naming service port conflict

  - by Kramer

  I am having trouble getting JBoss started. I am running JBoss 5.1.0 on Mac OSX (yes, I know it is an old version, but that’s what the application is certified on for now). I am using Apple’s JVM 1.6.0_37. I get the following error when trying to use JBoss (there are some more exceptions, but these are the first few): Error installing to Start: name=jboss:service=Naming state=Create mode=Manual requiredState=Installed java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) at sun.rmi.transport.tcp.TCPTransport.exportObject(TCPTransport.java:218) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:383) 16:57:15,596 ERROR [AbstractKernelController] Error installing to Real: name=vfsfile:/Users/home/server/jboss-5.1.0.GA/server/myserver/conf/jboss-service.xml state=PreReal mode=Manual requiredState=Real org.jboss.deployers.spi.DeploymentException: Error deploying: jboss:service=Naming at org.jboss.deployers.spi.DeploymentException.rethrowAsDeploymentException(DeploymentException.java:49) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:118) at org.jboss.system.deployers.ServiceDeployer.deploy(ServiceDeployer.java:46) Caused by: java.rmi.server.ExportException: Port already in use: 1098; nested exception is: java.net.BindException: Can't assign requested address at sun.rmi.transport.tcp.TCPTransport.listen(TCPTransport.java:310) Caused by: java.net.BindException: Can't assign requested address at java.net.PlainSocketImpl.socketBind(Native Method) Now I know what you are thinking, that I am running something that conflicts with that port, but I have used lsof and there is nothing listed on that port.

I also installed a network monitoring tool on my box and it doesn't look like any ports are being opened when I start jboss, but it is possible, that the tool might be missing a port that is opened and then closed quickly. Any ideas what could be the problem or how to fix it?

• I can't delete a directory inside a junctioned directory

  - by Fredy Muñoz

  So this is the deal. A couple of days ago I moved my profile folder C:\Documents and Settings\fmunoz to a different drive D:\fmunoz. Today, I created a directory in my desktop using the point-and-click method: Right-click on an empty space in the desktop Select New Select Folder Leave the default name New Folder and press Enter I tried to delete the folder using the point-and-click method: Right-click the New Folder directory Select Delete After five seconds, I got the following message: --------------------------- Error Deleting File or Folder --------------------------- Cannot delete New Folder: Access is denied. Make sure the disk is not full or write-protected and that the file is not currently in use. --------------------------- Initially I thought that there must be some sort of indexing services locking the directory so I got a list of open files using the TuneUp Process Manager tool but the New Folder directory wasn't there. I double-clicked My Computer, navigated to the desktop directory C:\Documents and Settings\fmunoz\Destkop, tried to delete the New Folder directory using the same point-and-click method described above and got exactly the same message at the same amount of time. In the same window, I navigated to the actual location of the desktop directory D:\fmunoz\Desktop, tried to delete the New Folder directory and this time it worked. I thought that this behavior was due to some special treatment that Windows gives to the desktop or the profile directories so I tried doing the same thing with a different set of directories: Created a folder D:\dummy Created a junction C:\dummy pointing to D:\dummy Created a New Folder directory in C:\dummy Tried to delete New Folder from C:\dummy. Didn't work. Tried to delete New Folder from D:\dummy. It worked. I tried creating the folder in the actual directory rather than the junction directory: Created a New Folder directory in D:\dummy Tried to delete New Folder from C:\dummy. Didn't work. Tried to delete New Folder from D:\dummy. It worked. I also tried using the Delete button instead of using the Delete option of the context menu but it didn't work. When using the Shift+Delete sequence, it works. It also works by using the rd command in the console, but in both cases the deleted directory doesn't goes to the Recycle Bin, which is my intention when using the Delete context menu option or the Delete button.

• Reviews Cheyney Group Marketing: What accounting softwares are available in the market for small businesses?

  - by user225556

  Accounting is the language of business, and good accounting software can save you hundreds of hours at the business equivalent of Berlitz. There's no substitute for an accounting pro who knows the ins and outs of tax law, but today's desktop packages can help you with everything from routine bookkeeping to payroll, taxes, and planning. Each package also produces files that you can hand off to an accountant as needed. Small-business managers have more accounting software options than ever, including subscription Web-based options that don't require their users to install or update software. Many businesses, however--including those that need to track large inventories or client databases, and those that prefer not to entrust their data to the cloud--may be happier with a desktop tool. We looked at three general-purpose, small-business accounting packages: Acclivity AccountEdgePro 2012 (both the product and the company were previously called MYOB), Intuit QuickBooks Premier 2012, and Sage's Sage 50 Complete 2013 (the successor to Peachtree Complete). All three packages offer a solid array of tools for tracking income and expenses, invoicing, managing payroll, and creating reports. These full-featured and highly mature programs don't come cheap. Acclivity AccountEdge Pro, at $299, is the least expensive; and prices climb if you opt to use common time-saving add-ons such as payroll services, or if you add licenses for multiple user accounts. All three are solid on the basics, but they have distinct differences in style and focus. The more you know about your accounting requirements, the more closely you'll want to look at the software you're thinking of buying. Sage 50 Complete should appeal most to people who understand the fine points of accounting and can use the product's many customization features (especially for businesses that manage inventory). QuickBooks works hard to appeal to newbies who need only the basics and might be intimidated by the level of detail and technical language exposed in the other two packages. At the same time, it also has a slew of third-party add-ons that meet specific needs and greatly expand its capabilities. AccountEdge Pro balances accessibility with a strong feature set at an affordable price. It's especially suitable for businesses that need to provide simultaneous access to multiple users.

• Linux: find out what process is using all the RAM?

  - by Timur

  Before actually asking, just to be clear: yes, I know about disk cache, and no, it is not my case :) Sorry, for this preamble :) I'm using CentOS 5. Every application in the system is swapping heavily, and the system is very slow. When I do free -m, here is what I got: total used free shared buffers cached Mem: 3952 3929 22 0 1 18 -/+ buffers/cache: 3909 42 Swap: 16383 46 16337 So, I actually have only 42 Mb to use! As far as I understand, -/+ buffers/cache actually doesn't count the disk cache, so I indeed only have 42 Mb, right? I thought, I might be wrong, so I tried to switch off the disk caching and it had no effect - the picture remained the same. So, I decided to find out who is using all my RAM, and I used top for that. But, apparently, it reports that no process is using my RAM. The only process in my top is MySQL, but it is using 0.1% of RAM and 400Mb of swap. Same picture when I try to run other services or applications - all go in swap, top shows that MEM is not used (0.1% maximum for any process). top - 15:09:00 up 2:09, 2 users, load average: 0.02, 0.16, 0.11 Tasks: 112 total, 1 running, 111 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 0.0%sy, 0.0%ni,100.0%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 4046868k total, 4001368k used, 45500k free, 748k buffers Swap: 16777208k total, 68840k used, 16708368k free, 16632k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ SWAP COMMAND 3214 ntp 15 0 23412 5044 3916 S 0.0 0.1 0:00.00 17m ntpd 2319 root 5 -10 12648 4460 3184 S 0.0 0.1 0:00.00 8188 iscsid 2168 root RT 0 22120 3692 2848 S 0.0 0.1 0:00.00 17m multipathd 5113 mysql 18 0 474m 2356 856 S 0.0 0.1 0:00.11 472m mysqld 4106 root 34 19 251m 1944 1360 S 0.0 0.0 0:00.11 249m yum-updatesd 4109 root 15 0 90152 1904 1772 S 0.0 0.0 0:00.18 86m sshd 5175 root 15 0 90156 1896 1772 S 0.0 0.0 0:00.02 86m sshd Restart doesn't help, and, by they way is very slow, which I wouldn't normally expect on this machine (4 cores, 4Gb RAM, RAID1). So, with that - I'm pretty sure that this is not a disk cache, who is using the RAM, because normally it should have been reduced and let other processes to use RAM, rather then go to swap. So, finally, the question is - if someone has any ideas how to find out what process is actually using the memory so heavily?

• Resetting root password on Fedora Core 3 - serial cable access only

  - by Sensible Eddie

  A little background: We have an old rackmount server running a customised version of Fedora, manufactured by a company called Navaho. The server is a TeamCAT, running some proprietary rubbish called Freedom2. We have to keep it going - the alternative is extraordinarily expensive, and the business is not likely to be running much longer to justify changing things. Through one means or another, it has fallen upon me to try and resolve our lack of root access. The previous admin has fallen under the proverbial bus, and nobody has any clue. We have no access to the root account for this server. ssh is running on the server, and there is one account admin that we can login with, however it has no permission to do anything (ironic...) The only other way into the server is with a null-modem serial cable. This works... up to a point. I can see the BIOS, I can see the post BIOS screen, and then I see "Starting grub", followed by another screen with about four lines of Linux information, but then it stops at that point. The server continues booting, and all services come online after around two minutes, but the serial terminal displays no more information. I understand it is possible to put Linux into "single user mode" to reset a root password, but I have no idea how to do this beyond trying to interrupt it at the grub stage listed above. When I have tried it just froze. It was almost like grub had appeared (since the server did not continue booting) but I couldn't see it on the serial terminal. Which made me think maybe the grub screen has some different serial settings? I don't know... it's the first time I've ever used serial for access! A friend of mine suggested trying to use a Fedora boot CD. We could boot from USB, so something along this approach is possible but again we still can only see what's going on with the serial terminal, so it might not be achievable. Does anyone have any suggestions for things I can try? I appreciate this is a bit of a long shot, but any assistance would be invaluable. *UPDATE 1 - 28/8/12 * - we will be making some attempts on this today and will post further details later!

• Server to server replication and CPU and 32k\ corrupt doc

  - by nick wall

  Summary: if database contains a doc with 32K issue or corrupt, on server to server replication it causes marked increase in CPU in nserver.exe task, which effectively causes our server(s) to slow right down. We have a 5 server cluster (1 "hub" and 4 HTTP servers accessed via reverse proxy and SSO for load balancing and redundancy). All are physically located next to each other on network, they don't have dedicated network\ ports for cluster or replication. I realise IBM recommendation is dedicated port for cluster. Cluster queues are in tolerance and under heavy application user load, i.e. the maximum number of documents are being created, edited, deleted, the replication times between servers are negligible. Normally, all is well. Of the servers in the cluster, 1 is considered the "hub", and imitates a PUSH-PULL replication with it's cluster mates every 60mins, so that the replication load is taken by the hub and not cluster mates. The problem we have: every now and then we get a slow replication time from the hub to a cluster mate, sometimes up to 30mins. This maxes out the nserver.exe task on the "cluster mate" which causes it to respond to http requests very slowly. In the past, we have found that if a corrupt document is in the DB, it can have this affect, but on those occasions, the server log will show the corrupt doc noteId, we run fixup, all well. But we are not now seeing any record of corrupt docs. What we have noticed is if a doc with the 32K issue is present, the same thing can happen. Our only solution in that case is to run a : fixup mydb.nsf -V, which shows it is purging a 32K doc. Luckily we run a reverse proxy, so we can shut HTTP servers down without users noticing, but users do notice when a server has the problem! Has anyone else seen this occur? I have set up DDM event handlers for many of the replication events. I have set the replication time out limit to 5 mins (the max we usually see under full user load is 0.1min), to prevent it rep'ing for 30mins as before. This ia a temporary work around. Does anyone know of a DDM event to trap the 32K issue? we could at least then send alert. Regarding 32K issue: this prob needs another thread, but we are finding this relatively hard to find the source of the issue as the 32K event is fairly rare. Our app is fairly complex, interacting with various other external web services, with 2 way data transfer. But if we do encounter a 32K doc, we can't look at field properties, so we can't work out which field has issue which would give us a clue as to which process is culprit. As above, we run a fixup -V. Any help\ comments on this would be gratefully received.

• Reviews Cheyney Group Marketing: What accounting softwares are available in the market for small businesses?

  - by user224313

  Accounting is the language of business, and good accounting software can save you hundreds of hours at the business equivalent of Berlitz. There's no substitute for an accounting pro who knows the ins and outs of tax law, but today's desktop packages can help you with everything from routine bookkeeping to payroll, taxes, and planning. Each package also produces files that you can hand off to an accountant as needed. Small-business managers have more accounting software options than ever, including subscription Web-based options that don't require their users to install or update software. Many businesses, however--including those that need to track large inventories or client databases, and those that prefer not to entrust their data to the cloud--may be happier with a desktop tool. We looked at three general-purpose, small-business accounting packages: Acclivity AccountEdgePro 2012 (both the product and the company were previously called MYOB), Intuit QuickBooks Premier 2012, and Sage's Sage 50 Complete 2013 (the successor to Peachtree Complete).

• OpenVPN Chaining

  - by noderunner

  I'm trying to set up an OpenVPN "chain", similar to what is described here. I have two separate networks, A and B. Each network has an OpenVPN server using a standard "road warrior" or "client/server" approach. A client can connect to either one for access to the hosts/services on that respective network. But server A and B are also connected to each other. The servers on each network have a "site-to-site" connection between the two. What I'm trying to accomplish, is the ability to connect to network A as a client, and then make connections with hosts on network B. I'm using tun/routing for all of the VPN connections. The "chain" looks something like this: [Client] --- [Server A] --- [Server A] --- [Server B] --- [Server B] --- [Host B] (tun0) (tun0) (tun1) (tun0) (eth0) (eth0) The whole idea is that server A should route traffic destined to network B through the "site-to-site" VPN set up on tun1 when a client from tun0 tries to connect. I did this simply by setting up two connection profiles on server A. One profile is a standard server config running on tun0, defining a virtual client network, IP address pool, pushing routes, etc. The other is a client connection to Server B running on tun1. With ip_forwarding enabled, I then simply added a "push route" to the clients advertising a route to network B. On server A, this seems to work when I look at tcpdump output. If I connect as a client, and then ping a host on network B, I can see the traffic getting passed from tun0 to tun1 on Server A: tcpdump -nSi tun1 icmp The weird thing is that I don't see Server B receiving that traffic through the tunnel. It's as if Server A is sending it through the site-to-site connection like it should, but server B is completely ignoring it. When I look for the traffic on Server B, it simply isn't there. A ping from Server A -- Host B works fine. But a ping from a client connected to Server A to host B does not. I'm wondering if Server B is ignoring the traffic because the source IP does not match the client IP pool that it hands out to clients? Does anyone know if I need to do something on Server B in order for it to see the traffic? This is a complicated problem to explain, so thanks if you stuck with me this far.

• What else can I do to secure my Linux server?

  - by eric01

  I want to put a web application on my Linux server: I will first explain to you what the web app will do and then I will tell you what I did so far to secure my brand new Linux system. The app will be a classified ads website (like gumtree.co.uk) where users can sell their items, upload images, send to and receive emails from the admin. It will use SSL for some pages. I will need SSH. So far, what I did to secure my stock Ubuntu (latest version) is the following: NOTE: I probably did some things that will prevent the application from doing all its tasks, so please let me know of that. My machine's sole purpose will be hosting the website. (I put numbers as bullet points so you can refer to them more easily) 1) Firewall I installed Uncomplicated Firewall. Deny IN & OUT by default Rules: Allow IN & OUT: HTTP, IMAP, POP3, SMTP, SSH, UDP port 53 (DNS), UDP port 123 (SNTP), SSL, port 443 (the ones I didn't allow were FTP, NFS, Samba, VNC, CUPS) When I install MySQL & Apache, I will open up Port 3306 IN & OUT. 2) Secure the partition in /etc/fstab, I added the following line at the end: tmpfs /dev/shm tmpfs defaults,rw 0 0 Then in console: mount -o remount /dev/shm 3) Secure the kernel In the file /etc/sysctl.conf, there are a few different filters to uncomment. I didn't know which one was relevant to web app hosting. Which one should I activate? They are the following: A) Turn on Source Address Verification in all interfaces to prevent spoofing attacks B) Uncomment the next line to enable packet forwarding for IPv4 C) Uncomment the next line to enable packet forwarding for IPv6 D) Do no accept ICMP redirects (we are not a router) E) Accept ICMP redirects only for gateways listed in our default gateway list F) Do not send ICMP redirects G) Do not accept IP source route packets (we are not a router) H) Log Martian Packets 4) Configure the passwd file Replace "sh" by "false" for all accounts except user account and root. I also did it for the account called sshd. I am not sure whether it will prevent SSH connection (which I want to use) or if it's something else. 5) Configure the shadow file In the console: passwd -l to lock all accounts except user account. 6) Install rkhunter and chkrootkit 7) Install Bum Disabled those services: "High performance mail server", "unreadable (kerneloops)","unreadable (speech-dispatcher)","Restores DNS" (should this one stay on?) 8) Install Apparmor_profiles 9) Install clamav & freshclam (antivirus and update) What did I do wrong and what should I do more to secure this Linux machine? Thanks a lot in advance

• windows 7 virtual wireless adapter keeps going to sleep

  - by conners

  Just a quick question that I can't see mentioned anywhere online. I have a Windows 7 box configured like these guys recommend http://www.itgeekdiary.com/windows-7-as-an-wi-fi-access-point/ simply so that I can have my Windows 7 box as a wifi access point or a wifi emitter. It's also called a Microsoft Virtual WiFi Miniport Adapter. But it powers off and shuts down automatically and stops working. Basically everything works as intended and then - well -it will stopped working when I am not at the Windows 7 PC for a long time. The problem seems to be that every time my PC goes to "power save / sleep" and in the morning the Windows 7 machine "wakes" but blooming heck the wifi has stopped and you have to power cycle the PC (which is very uncool). When I power Cycle I have to do the following as administrator C:\Windows\System32\netsh.exe wlan start hostednetwork I then tried a gazllion things involving services and power management and eventually discovered that if I run the following commands as administrator it will be ok (for a bit) but every 3rd ot 4th time I try this "trick" it simply fails. the trick that seems to work 3 out of 4 times (i.e. "most" of the time) C:\Windows\System32\netsh.exe wlan stop hostednetwork C:\Windows\System32\netsh.exe wlan start hostednetwork But why does this only work "some" of the time? What else I did by myself: on every manage adapter properties (that relates to the wifi) I right clicked [configure] [power management] /disabled/ "allow the computer to power off to save power" <- this made no difference Also (and this is a bit annoying) there is no system tray app/GUI for the Microsoft Virtual WiFi Miniport Adapter output signal ... none... so (lame as it sounds) the ONLY way I can check if it's on is to physically go to another device and SCAN.. lame so my question can probably be solved by any of the following: a) can I stop Windows 7 sleeping this wifi when the machine sleeps b) can I force Windows to force wake this process on wake? if so how? c) what is the service / process REALLY called and how do I restart it if it crashes d) how can I flush the wifi properly rather power cycle the host machine e) anyone have a link to an program or app that can sit in the system tray that shows windows 7 wifi hotspot emission status (on/off/etc etc) Since I am a programmer I can easily write a vbs script / windows exe to fix this (and I will share this solution) and the gui problem if I can work out the actual service that is running that netsh stops/starts

• Bridging and iptables SNAT conflict

  - by sad_admin

  Hello I am working on a setup here and have it working with one minor exception. Devices on one side of my bridge aren't getting SNAT'd to the Internet. The Diagram / Overview: Primary_Network (Site_A) | | Internet ------- Linux_Bridge_GW (GW) | | Secondary/CoLo Site (Site_B) Here is the setup: 1.) Site_A has all the production servers and workstations. 2.) Site_B has a set of servers that we would like to fail-over to and also serve our internet facing services from. 3.) GW has two interfaces that are trunked and carrying the appropriate VLAN traffic (allow layer-2 propagation of traffic between sites) //this all works perfectly fine. 4.) The problem that is being encountered is, hosts from Site_B have their default GW at Site_A (same subnet) GW does not have IPs on the VLANs that are being passed. 5.) All hosts at Site_A can reach the Internet without problem. 6.) GW has an addresses on a subnet that is ONLY for Internet destined traffic. (This was done so that Websense would not have to parse unnecessary traffic. We use this VLAN as the monitor port's source on the switch where Websense is sitting). What I think is happening: 1.) Packet/Frame comes in on physdev at Site_B destined for Internet. 2.) Kernel sees packet, and forwards it out the other side of the bridge to that host's default GW. 3.) Site_A (containing core-network's Default-GW) sees that packet is destined for a host it doesn't know about, so it sends it to it's default GW (the linux bridge, since it's Internet bound). 4.) The kernel says "Hey, I've seen you before" and therefore doesn't do SNAT'ing on the packet and sends it out to the Internet where it's black-holed. Why I think it's happening: 1.) A tcpdump on the internet facing NIC shows the packet leaving the interface with the private address as it's source. What I would like: 1.) Have the packet SNAT'd. 2.) Something like the below would be awesome a.) packet comes in from Site_B b.) kernel sees that the packet is NOT destined for itself or any private address c.) kernel says "OK, well since you're destined for the Internet I'm going to send you out this interface rather than forward you to your normal default GW that's WAAAY over there." d.) packet comes in from internet and is sent out the appropriate bridge physdev depending on which site the host it's destined for is at. Thanks for any assistance or guidance that you are willing to offer. Best Regards, Sad Admin

• Where is my app.config for SSIS?

  Sometimes when working with SSIS you need to add or change settings in the .NET application configuration file, which can be a bit confusing when you are building a SSIS package not an application. First of all lets review a couple of examples where you may need to do this. You are using referencing an assembly in a Script Task that uses Enterprise Library (aka EntLib), so you need to add the relevant configuration sections and settings, perhaps for the logging application block. You are using using Enterprise Library in a custom task or component, and again you need to add the relevant configuration sections and settings. You are using a web service with Microsoft Web Services Enhancements (WSE) 3.0 and hosting the proxy in SSIS, in an assembly used by your package, and need to add the configuration sections and settings. You need to change behaviours of the .NET framework which can be influenced by a configuration file, such as the System.Net.Mail default SMTP settings. Perhaps you wish to configure System.Net and the httpWebRequest header for parsing unsafe header (useUnsafeHeaderParsing), which will change the way the HTTP Connection manager behaves. You are consuming a WCF service and wish to specify the endpoint in configuration. There are no doubt plenty more examples but each of these requires us to identify the correct configuration file and and make the relevant changes. There are actually several configuration files, each used by a different execution host depending on how you are working with the SSIS package. The folders we need to look in will actually vary depending on the version of SQL Server as well as the processor architecture, but most are all what we can call the Binn folder. The SQL Server 2005 Binn folder is at C:\Program Files\Microsoft SQL Server\90\DTS\Binn\, compared to C:\Program Files\Microsoft SQL Server\100\DTS\Binn\ for SQL Server 2008. If you are on a 64-bit machine then you will see C:\Program Files (x86)\Microsoft SQL Server\90\DTS\Binn\ for the 32-bit executables and C:\Program Files\Microsoft SQL Server\90\DTS\Binn\ for 64-bit, so be sure to check all relevant locations. Of course SQL Server 2008 may have a C:\Program Files (x86)\Microsoft SQL Server\100\DTS\Binn\ on a 64-bit machine too. To recap, the version of SQL Server determines if you look in the 90 or 100 sub-folder under SQL Server in Program Files (C:\Program Files\Microsoft SQL Server\nn\) . If you are running a 64-bit operating system then you will have two instances program files, C:\Program Files (x86)\ for 32-bit and  C:\Program Files\ for 64-bit. You may wish to check both depending on what you are doing, but this is covered more under each section below. There are a total of five specific configuration files that you may need to change, each one is detailed below: DTExec.exe.config DTExec.exe is the standalone command line tool used for executing SSIS packages, and therefore it is an execution host with an app.config file. e.g. C:\Program Files\Microsoft SQL Server\90\DTS\Binn\DTExec.exe.config The file can be found in both the 32-bit and 64-bit Binn folders. DtsDebugHost.exe.config DtsDebugHost.exe is the execution host used by Business Intelligence Development Studio (BIDS) / Visual Studio when executing a package from the designer in debug mode, which is the default behaviour. e.g. C:\Program Files\Microsoft SQL Server\90\DTS\Binn\DtsDebugHost.exe.config The file can be found in both the 32-bit and 64-bit Binn folders. This may surprise some people as Visual Studio is only 32-bit, but thankfully the debugger supports both. This can be set in the project properties, see the Run64BitRuntime property (true or false) in the Debugging pane of the Project Properties. dtshost.exe.config dtshost.exe is the execution host used by what I think of as the built-in features of SQL Server such as SQL Server Agent e.g. C:\Program Files\Microsoft SQL Server\90\DTS\Binn\dtshost.exe.config This file can be found in both the 32-bit and 64-bit Binn folders devenv.exe.config Something slightly different is devenv.exe which is Visual Studio. This configuration file may also need changing if you need a feature at design-time such as in a Task Editor or Connection Manager editor. Visual Studio 2005 for SQL Server 2005  - C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe.config Visual Studio 2008 for SQL Server 2008  - C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe.config Visual Studio is only available for 32-bit so on a 64-bit machine you will have to look in C:\Program Files (x86)\ only. DTExecUI.exe.config The DTExec UI tool can also have a configuration file and these cab be found under the Tools folders for SQL Sever as shown below. C:\Program Files\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\DTExecUI.exe C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\DTExecUI.exe A configuration file may not exist, but if you can find the matching executable you know you are in the right place so can go ahead and add a new file yourself. In summary we have covered the assembly configuration files for all of the standard methods of building and running a SSIS package, but obviously if you are working programmatically you will need to make the relevant modifications to your program’s app.config as well.

• Aggregate SharePoint Event/Items into your Calendar view using Calendar Overlay

  - by eJugnoo

  One of the most common features I have seen in common use for SharePoint (prior to 2010) in Intranet environments for Team site is Calendar’s. Not only the Calendar list type, but also the ability to add a Calendar view to any list that has the desired columns to construct a Calendar – such as Start, End, Title etc. While this was all great for a single site/calendar, the problem of having to track numerous calendar’s remained. With introduction of Outlook 2007 bi-directional integration with SharePoint, and particularly the ability of Outlook to overlay calendar helped bridge the gap. Now one could connect to number of team sites, and setup Calendar overlays in Outlook using varying colours, to easily identify event source and yet benefit from the plotting of events on single Calendar view. This was all good, but each user in your Enterprise was supposed to setup in a “pull” fashion. This is good for flexibility, not so good when you need to “push” consistency and productivity (re-use). So, what was missing on SharePoint is the ability to have server-side overlay’s that everyone can see – in a single place, aggregating multiple sources. Until SharePoint 2010 arrived! Calendars Overlay in SharePoint 2010 There are Calendar lists and Calendar views. View can be created for almost all lists, as far as you have desired column’s in a list like Start, End, Title etc. to be able to describe and plot an item in a Calendar format. In SharePoint 2010, create a new Calendar list. Go to Calendar ribbon tab, and click Calendar Overlay. You get the screen with list of existing Overlay’s associated with current Calendar (list – in our case). Click on “New Calendar”… Notice the breadcrumb! You are adding Overlay to existing list (Team Calendar – in our case). You have choice of “pulling” Calendar info from an existing Calendar (list/view) in SharePoint or even from Exchange! Set standard info like a name, description and decide the colour you want for the items in aggregated Calendar overlay. Select the source site/list/view, anywhere in farm. When you select Exchange as source of Calendar, you get option to add OWA and Exchange Web Service url. I will cover details of connecting with Exchange in another post, and focus on Overlay’s with SharePoint for this one. Once you have added a new Calendar overlay to existing Calendar veiw, you get something like below for Day view, Week view, and Month view respectively Notice the Overlay colours: Now, if you decide to connect this Calendar to Outlook to sync the items, it will only sync items from main view, and not from Overlay source. So such Overlay of calendar’s is server-side aggregation only. That increases my curiosity, so I try adding the Calendar list view as a web-part on a new page. As you see, this instance of view didn’t include item from source that we had added to default Calendar view. This is – probably – due to the fact that this is a new web-part view for the page. If you want to add overlay to this one, you have to redo that from Ribbon. This also means, subject to purpose and context you get the flexibility to decide what overlay is suited. Also you can only add 10 Overlay’s to an existing view instance. Conclusion Calendar Overlay is clearly a very useful feature that fills a gap of not being able to aggregate information from multiple sources into a Calendar view within context of current items. Source of items can be existing SharePoint calendar views on any site, or even Exchange (via OWA/Exchange web services). List type for source doesn’t matter, it just need a Calendar view type available. You can have 10 overlays. Overlays are for the specific view only, and are server-side only – which means they do not get synced in Outlook. While you can drag-drop current list items, you cannot edit overlay items as they are read-only within scope of current Calendar view. You can of course click on source Overlay item to edit at the source. I’d like to hear, how you think Overlay’s will help you in your case, or how you are already using them... Enjoy SharePoint! --Sharad
