• Is Visual Studio Express Edition 2010 free?

  - by RyanTM

  Is Visual Studio Express Edition 2010 free? On this page: http://www.microsoft.com/express/Windows/ it says it is a set of free tools. But the splash screen at the start says it is only for evaluation purposes. And the about screen has a trial countdown timer counting down the days to when it presumably stops working.

• Iptables config breaks Java + Elastic Search communication

  - by Agustin Lopez

  I am trying to set up a firewall for a server hosting a java app and ES. Both are on the same server and communicate to each other. The problem I am having is that my firewall configuration prevents java from connecting to ES. Not sure why really.... I have tried lot of stuff like opening the port range 9200:9400 to the server ip without any luck but from what I know all communication inside the server should be allowed with this configuration. The idea is that ES should not be accessible from outside but it should be accessible from this java app and ES uses the port range 9200:9400. This is my iptables script: echo -e Deleting rules for INPUT chain iptables -F INPUT echo -e Deleting rules for OUTPUT chain iptables -F OUTPUT echo -e Deleting rules for FORWARD chain iptables -F FORWARD echo -e Setting by default the drop policy on each chain iptables -P INPUT DROP iptables -P OUTPUT ACCEPT iptables -P FORWARD DROP echo -e Open all ports from/to localhost iptables -A INPUT -i lo -j ACCEPT echo -e Open SSH port 22 with brute force security iptables -A INPUT -p tcp -m tcp --dport 22 -m state --state NEW -m recent --set --name SSH --rsource iptables -A INPUT -p tcp -m tcp --dport 22 -m recent --rcheck --seconds 30 --hitcount 4 --rttl --name SSH --rsource -j REJECT --reject-with tcp-reset iptables -A INPUT -p tcp -m tcp --dport 22 -m recent --rcheck --seconds 30 --hitcount 3 --rttl --name SSH --rsource -j LOG --log-prefix "SSH brute force " iptables -A INPUT -p tcp -m tcp --dport 22 -m recent --update --seconds 30 --hitcount 3 --rttl --name SSH --rsource -j REJECT --reject-with tcp-reset iptables -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT echo -e Open NGINX port 80 iptables -A INPUT -p tcp --dport 80 -j ACCEPT echo -e Open NGINX SSL port 443 iptables -A INPUT -p tcp --dport 443 -j ACCEPT echo -e Enable DNS iptables -A INPUT -p tcp -m tcp --sport 53 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT iptables -A INPUT -p udp -m udp --sport 53 --dport 1024:65535 -m state --state ESTABLISHED -j ACCEPT And I get this in the java app when this config is in place: org.elasticsearch.cluster.block.ClusterBlockException: blocked by: [SERVICE_UNAVAILABLE/1/state not recovered / initialized];[SERVICE_UNAVAILABLE/2/no master]; at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues(AutowiredAnnotationBeanPostProcessor.java:292) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1185) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:537) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:475) at org.springframework.beans.factory.support.AbstractBeanFactory$1.getObject(AbstractBeanFactory.java:304) at org.springframework.beans.factory.support.DefaultSingletonBeanRegistry.getSingleton(DefaultSingletonBeanRegistry.java:228) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:300) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:195) at org.springframework.beans.factory.support.DefaultListableBeanFactory.preInstantiateSingletons(DefaultListableBeanFactory.java:700) at org.springframework.context.support.AbstractApplicationContext.finishBeanFactoryInitialization(AbstractApplicationContext.java:760) at org.springframework.context.support.AbstractApplicationContext.refresh(AbstractApplicationContext.java:482) at org.springframework.web.context.ContextLoader.configureAndRefreshWebApplicationContext(ContextLoader.java:403) Do any of you see any problem with this configuration and ES?

• Can an administration extraction of an MSI file perform registry and/or system wide changes?

  - by Wil

  I am always getting MSI (or setup EXEs which are basically MSI) files, and half the time they really do not need to be a setup. Microsoft is probably one of the biggest sources - almost every time I want to download a little source code sample, it has a MSI which if you install, only usually has three files. I would rather not do an install and add it to the add/remove programs and who knows what else (although I am sure it wouldn't be that bad) for the sake of three files! For this reason, I always use the following command: MSIEXEC /a <filename.msi> /qb TARGETDIR=<directory name> Now, this works fine and I have never had problems... However, I was just browsing some articles on Technet and found the following resource about administration installs. Apparently, MSI files can have two sequences: The AdminUISequence Table and the AdminExecuteSequence Table. I am not so worried about the AdminUISequence Table as it states that "The installer skips the actions in this table if the user interface level is set to basic UI or no UI", and this is what the /qb switch I use does. However, there is nothing similar written against AdminExecuteSequence Table. I realise that many people who write MSI files simply do it for a single end user and probably do not even touch the admin install options, however, is it possible for them to set items that can affect the system and if so, is there a fail proof way of extracting? I do already use 7-zip, however despite it being on the "supported" page, MSI support is lacking... well... completely sucks. It looses the file names and is generally useless. They have a bug which was closed with no reason/resolution over three years ago, and I opened a forum post and haven't had a reply. I would not really want to install any additional programs if I could help it and just want peoples opinions on this. Thanks. edit - Should also say, I run with UAC on, and I have never ever had a elevation prompt whilst performing the MSIEXEC operation, so I am guessing I have never had a system wide change, however, I am still curious as to if it is possible... As if changes (even just to the user) are possible I would do this locally/in a VM and never on a server or place of importance!

• Create tunnel through an open SSH connection?

  - by criptych

  I have a remote PC (behind NAT and firewall) set up to create a reverse SSH tunnel to my home PC/server (DMZed). Unfortunately, the tunnel hasn't been working lately. Fortunately -- I think -- the remote PC currently has an SFTP session open to the local one. My question is, can I create a tunnel back to the remote PC through that session? Or am I SOL until I can physically get in to restore the reverse tunnel on the remote PC?

• How do I configure the number of worker threads used by SqlServer 2005 Agent

  - by Decker

  How can I increase the limit of worker threads from the default 10 for SQL Server 2005 SqlAgent? I have 9 jobs that run almost continuously and that leaves only one available thread for the rest of the scheduled jobs. Oftentimes, when no thread is available, I will see the jobs in "Waiting for worker thread" state. I'd like to increase the number to about 12 (which should do the trick for me). Any idea where this is set?

• Why is user asked to choose their workgroup?

  - by Clinton Blackmore

  We running Mac OS X Server 10.5.8 with Mac OS X 10.5.8 clients. Students use network logins to, well, log in. I've been asked to deny internet access to a specific user. I was told that a good way to do it is to create a user workgroup called "No Internet Access" and manage settings there. (Specifically, I told parental controls to allow access to no sites, and blacklisted all the installed web browsers). Now, when the user authenticates to log in, they are greeted with this dialog: Workgroups for <username> Grade 7 Students No Internet Access It is unlikely that the student would willing choose "No Internet Access" to be their base group. Looking in Workgroup Manager at the student's record, it shows their primary group ID is the grade 7 group, and "No Internet Access" is listed as another group they belong to. I looked at the managed preferences for all the computers pertaining to logins. They are set to their defaults. Specifically, the computer groups' preference for Logins - Access has the defaults: [unchecked] Ignore workgroup nesting [checked] Combine available workgroup settings Based on my reading of Tips and Tricks for Mac Administrators, this should be correct, the user should not be asked which group they belong to, and settings from all applicable groups should be applied. How can I achieve that result? Edit: I've decided to add some additional information from the Tips and Tricks for Mac Management White Paper (via Apple in Education, via the author's site). On page 21, it says: With Leopard MCX, workgroup preference settings are combined by default into a single set of values. This means that instead of having to choose between the Math, Science, or Language Arts workgroups when logging in, a user can just authenticate and be taken directly to the desktop. All the settings for each of those workgroups are composited together, providing you with all the Dock items and a composite of all the other settings. On page 40, an example is given in which settings are combined from different 'domains', one computer group, two (user) workgroups, and one individual user's settings. [When johnd logs into a leopard client,] the items staged in the Dock from left to right are: computer group, first workgroup alphabetically, second workgroup, user. Items within the workgroup are staged alphabetically. Nowhere is there an indication that groups are nested; indeed, I can see no sensible (non-flat) heirarchy for groups like Math, Science, and Language Arts. I strongly believe that there is a way to apply settings from two unrelated user workgroups such that a user of OS X 10.5.x or newer does not need to choose their workgroup. This is what I seek to achieve.

• dnsmasq acts as the DHCP server for selected nodes overriding the existing DHCP server on the same LAN?

  - by user183394

  I am trying to set up a small "lab" at home. Like many modern homes, I have a regular DSL service which comes with a 2Wire 3600HGV router, which acts also as a DHCP server. Since I would like to PXE boot a few computers in my "lab" The 2Wire is inflexible to adjustments that I want to do I have used dnsmasq at work so I would like to use dnsmasq as the DHCP server for the few nodes in my "lab" if feasible. In the dnsmasq man page, there is the following: [...] -K, --dhcp-authoritative (IPv4 only) Should be set when dnsmasq is definitely the only DHCP server on a network. It changes the behaviour from strict RFC compliance so that DHCP requests on unknown leases from unknown hosts are not ignored. This allows new hosts to get a lease without a tedious timeout under all circumstances. It also allows dnsmasq to rebuild its lease database without each client needing to reacquire a lease, if the database is lost. [...] As far as I know, the ISC DHCP server can use the following to do what I would like to accomplish: authoritative; [...] subnet 192.168.1.0 netmask 255.255.255.0 { host nb0 { # only give DHCP information to this computer: hardware ethernet e8:9a:8f:17:70:42; fixed-address 192.168.1.10; option subnet-mask 255.255.255.0; option routers 192.168.1.254; option domain-name-servers 192.168.1.254; # Non-essential DHCP options filename "/pxelinux.0"; } [...] But I much prefer dnsmasq's "all-in-one-ness". My question: do I have to couple the -K option with something else? As shown in the example above, the ISC DHCP server requires the mac addresses of managed nodes to be explicitly specified. Does dnsmasq have something similar? FYI, the machine on which I plan to run dnsmasq runs CentOS 6.3 64bit. It has a statically assigned IP address: 192.168.1.3.

• Git on DreamHost still balking on big files even after I compiled with NO_MMAP=1

  - by fuzzy lollipop

  I compiled Git 1.7.0.3 on DreamHost with the NO_MMAP=1 option, I also supplied that option when I did the "make NO_MMAP=1 install". I have my paths set up correctly, which git reports my ~/bin dir which is correct, git --version returns the correct version. But when I try to do a "git push origin master" with "big" files ~150MB it always fails. Does anyone have an suggestions on how to get DreamHost to accept this "big" files from a git push?

• How to hide all filenames during thumbnail view? Windows 7

  - by Saebin

  When you use the right click 'View - Hide file names' option it really only works on preset file extensions.... which is not really helpful when you have extensions with thumbnails windows isn't set to hide (ie, flv files). Not only that, you may have other files mixed in with media files that aren't hidden either (exe, zip, etc). Is there some way to hide all file names or add additional extensions to hide?

• Is there a way to make software available for remote installation in Windows Server?

  - by Michael J. Gray

  I've heard of folks having a sort of "software repository" which contains a database of product keys and then network installation media for operating systems and other Microsoft software, such as Office. With this, they were then able to join a computer to the domain and grant that user privileges to a set of software and then the client was able to use it either remotely or locally on their machine. I believe it installed from the server on to their local machine. Does anyone happen to know what this is?

• Vmware Player Network adaptors have no network or internet access in windows 7 enterprise

  - by daffers

  As per the title. My VMWare player installation has setup the two network adaptor VMnet1 and VMnet8 and they are picked up as unidentified networks with no network access (i need this to activate my windows server installation on it). The option to change the network location is not available (this might be because of network policy on the domain despite having set this as configurable in the local security policy section). Is there anyway i can change how these networks are detected or alter the configuration of vmware to get around this?

• Directory listing through FTPS (TLS) is not working

Some facts: Server uses Pure-FTPD Server has a passive port range configured Server has no firewall limitations regarding the FTP Client uses WS FTP Client is behind a router Client connects to the same IP as every other, using PASSIVE mode All other clients have no trouble connecting Because of the TLS requirement, connecting using ACTIVE mode is almost not possible, but PASSIVE is working fine for everyone except this specific client.

• route lan traffic through wirless mifi

  - by Randall Blake

  I have a Windows 7 laptop accessing the internet through Verizon wireless MIFI configured as 192.168.1.1. It supports only 5 wireless connections, so I don't want to use up connections unnecessarily. That laptop has an ethernet nic which I have given a static IP of 192.168.0.5. Everything else on the 192.168.0.0 network acquires an address via DHCP from a DLink router whose address is 192.168.0.1. Also on that network are a printer, some network cameras, and a linux pc. The linux pc does not have a wireless card (and I don't want to buy one). The linux pc is located at 192.168.0.122. I can ping the linux pc from the windows pc. But I cannot access the internet from the linux pc. I can ping everything on the 192.168.0.0 network EXCEPT the ethernet card in the Windows PC. It seems as though my DLink router will not route requests to the 192.168.0.5 nic on the windows pc. My windows pc has a default route pointing to the 192.168.1.0 network. It also has a route telling it to route all traffic destined for the 192.168.0.0 network through the 192.168.0.5 interface. I have tried adding a default route to the linux pc to "gateway" 192.168.0.5, but that does not work. I have also tried adding a default route to the linux pc to the gateway 192.168.0.1 (the DLink router) but that will not give me internet access either (over the 192.168.1.0 network). I tried these two different routes at different times - I did not set them both at the same time. I suppose this is a simple problem to solve, but I cannot seem to solve it. How can I give internet access over the 192.168.1.1 MIFI to my linux pc on 192.168.0.122? Thanks EDIT: Additional Info Internet | | MIFI (192.168.1.1) (wireless) | | (192.168.1.3) (wireless) Windows 7 PC Dlink Router (192.168.0.1) ------------ (192.168.0.5) (wired) | | |linux pc (192.168.0.122) (wired) | |printer (192.168.0.100) (wireless) | |network cameras, etc (192.168.0.103) (wireless) Only the windows pc is multi-homed with a wireless nic that connects to the MIFI wirelessly, and an ethernet nic with a wired connection to the DLink router. (The DLink permits both wired and wireless connections.) I don't want to use Windows internet connection sharing because I believe it will set up the ethernet nic as a gateway on 192.168.0.1 and a DHCP server. I already have the Dlink performing that role and I don't want to change that if I do not have to. (The Dlink permits me to make DHCP reservations and I really like that feature. I don't want to lose it.)

However, after I set the 403 ErrorDocument, I noticed that it didn't work when I tried to access the .htaccess file itself. When I access a different forbidden file, the Error Document appears just fine. How can I make the ErrorDocument work on the .htaccess file?

• Sendmail relay authentication

  - by Pawel Veselov

  I'm trying to set up my sendmail to authenticate against a relay (comcast). I'm not seeing any attempts to authenticate at all. I'm trying to just debug how authentication works, and can't connect all the pieces... I have, in my .mc file: define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl define(`SMART_HOST', `relay:smtp.comcast.net.')dnl define(`confAUTH_MECHANISMS', `PLAIN')dnl FEATURE(`authinfo',`hash /etc/mail/client-info')dnl And in my /etc/mail/client-info: AuthInfo:*.comcast.net "U:root" "I:comcast_user" "P:comcast_password" Now, I know everything is fine with the u/p, as I could authenticate directly through SMTP, using telnet. There are two things I don't understand. When AuthInfo records are searched for, they are matched by the target hostname. How? Does it it use the map key (something I would expect), or uses the so-called "Domain" ("R:" parameter that I don't set in my auth-info line) What is "U:", really? Sendmail README (http://www.sendmail.org/m4/smtp_auth.html) says it's "user(authoraztion id)", and "I:" is "authentication ID". That suggests that my username should be in "U:", actually, but http://www.sendmail.org/~ca/email/auth.html says that "I:" is your remote user name.
