  • How to transition to Comcast with static IP address [migrated]

    - by steveha
    I have my own email server in my house, on a static IP address. I have had business DSL for over a decade, but I also now have Comcast business Internet. I want to transition from the DSL to the Comcast, and I have some questions. I have a domain name, my own mail server, and a firewall (a PC with two network interfaces, running Devil-Linux). I need to make sure I understand how to set up the Comcast cable box, and how to set up my firewall. First, do I need to change any settings in the cable box? Currently I have only used the cable box by plugging in a laptop, with the laptop doing DHCP. I think I can leave the box alone but I would like to make sure. Second, I'm not sure I understand the instructions Comcast gave me for setting up the firewall. My DSL provider gave me the following information: static IP address, net mask, gateway, and two DNS servers. Comcast gave me: static IP address, routable static IP address, net mask, and two DNS servers, and told me to put the "static IP address" as the "gateway" on the firewall. Is this just Comcast-speak here? Does "routable static IP address" mean the same thing as "static IP address" in my DSL setup, the end-point address that I should publish in the DNS MX records for my email server? Or should I publish the "static IP address", and Comcast will then route all its traffic over the cable box? My plan is: first, I'm going to configure another firewall, so I have one firewall for the DSL and one for the Comcast (rather than madly editing settings to switch back and forth). Then I will publish the new Comcast static IP address as a backup email server address in the DNS MX records, wait a while to let it propagate, and then switch my home over from the DSL to the Comcast. Then I'll change DNS to make that the primary mail address and the DSL the secondary, let that go a while and make sure it seems reliable. Then I'll remove the DSL from the DNS MX records completely, and finally shut down the DSL service. (I thought about keeping the DSL as a backup, but the reason I'm leaving DSL is that it has become unreliable; and I have heard that Comcast business Internet is reliable.) Final question, any advice for me? Anything you think might be useful, helpful, or educational. Thanks.

  • How to diagnose repeated "Starting up database '<dbname>'"

    - by Richard Slater
    I have a SQL 2008 server which is predominantly used as a development server, in the last two weeks it has been having occasional "fits", I have isolated the cause of these fits as CHECKDB being run almost continuiously, the following log information is logged to the Windows Event Log (Source: MSSQLSERVER, Category: Server): Event: 1073758961, Message: Starting up database 'DBName1'. Event: 1073758961, Message: Starting up database 'DBName2'. Event: 1073759397, Message: CHECKDB for database 'DBName1' finished without errors on 2010-07-19 20:29:26.993 (local time). This is an informational message only; no user action is required. Event: 1073759397, Message: CHECKDB for database 'DBName1' finished without errors on 2010-07-19 20:29:26.993 (local time). This is an informational message only; no user action is required. This is repeated every 1-2 seconds untill SQL Server is restarted or the offending databases are detatched. I initially thought that it was a problem with the databases so I took a backup and restored them to a SQL Express instance, all of the data is in tact, and CHECKDB runs without problem. The two databases that were causing a problem last week were not being used; so I took full backups of them and detached the databases, this resolved the problem. However at 0100 GMT this morning to other totally unrelated databases started showing the same problems. There is nothing in the event log to suggest that something happened to the server such as a restart, there are no messages about processes crashing or issues being detected with the storage controller. Speaking to the owner of the company this computer has suffered from "gremlins" in the past, however advice was taken and the motherboard was replaced and the computer rebuilt, memory and processor are the same. Stats: O/S: Windows 2008 Standard Build 6002 CPU: 2x Pentium Dual-Core E5200 @ 2.5GHz RAM: 2GB SQL: 2008 Standard 10.0.2531 Edit: someone posted then deleted a comment about AutoClose, it was turned on on the databases affected. It seems that best practice is to disable it so I have done that with the folllowing. EXECUTE sp_MSforeachdb 'IF (''?'' NOT IN (''master'', ''tempdb'', ''msdb'', ''model'')) EXECUTE (''ALTER DATABASE [?] SET AUTO_CLOSE OFF WITH NO_WAIT'')' I won't know if the problem recurs for some time so I am still open to further answers.

  • netsh wlan add profile not importing passphrase

    - by sirlancelot
    I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings or am I missing something about adding profiles? Here is the exported xml with personal information removed: <?xml version="1.0"?> <WLANProfile xmlns="http://www.microsoft.com/networking/WLAN/profile/v1"> <name>[removed]</name> <SSIDConfig> <SSID> <hex>[removed]</hex> <name>[removed]</name> </SSID> <nonBroadcast>false</nonBroadcast> </SSIDConfig> <connectionType>ESS</connectionType> <connectionMode>auto</connectionMode> <autoSwitch>false</autoSwitch> <MSM> <security> <authEncryption> <authentication>WPAPSK</authentication> <encryption>TKIP</encryption> <useOneX>false</useOneX> </authEncryption> <sharedKey> <keyType>passPhrase</keyType> <protected>true</protected> <keyMaterial>[removed]</keyMaterial> </sharedKey> </security> </MSM> </WLANProfile> Any help or advice is appreciated. Thanks.

  • Django + gunicorn + virtualenv + Supervisord issue

    - by Florian Le Goff
    Dear all, I have a strange issue with my virtualenv + gunicorn setup, only when gunicorn is launched via supervisord. I do realize that it may very well be an issue with my supervisord and I would appreciate any feedback on a better place to ask for help... In a nutshell : when I run gunicorn from my user shell, inside my virtualenv, everything is working flawlessly. I'm able to access all the views of my Django project. When gunicorn is launched by supervisord at the system startup, everything is OK. But, if I have to kill the gunicorn_django processes, or if I perform a supervisord restart, once that gunicorn_django has relaunched, every request is answered with a weird Traceback : (...)

  • How do I protect a low budget network from rogue DHCP servers?

    - by Kenned
    I am helping a friend manage a shared internet connection in an apartment buildling with 80 apartments - 8 stairways with 10 apartments in each. The network is laid out with the internet router at one end of the building, connected to a cheap non-managed 16 port switch in the first stairway where the first 10 apartments are also connected. One port is connected to another 16 port cheapo switch in the next stairway, where those 10 apartments are connected, and so forth. Sort of a daisy chain of switches, with 10 apartments as spokes on each "daisy". The building is a U-shape, approximately 50 x 50 meters, 20 meters high - so from the router to the farthest apartment it’s probably around 200 meters including up-and-down stairways. We have a fair bit of problems with people hooking up wifi-routers the wrong way, creating rogue DHCP servers which interrupt large groups of the users and we wish to solve this problem by making the network smarter (instead of doing a physical unplugging binary search). With my limited networking skills, I see two ways - DHCP-snooping or splitting the entire network into separate VLANS for each apartment. Separate VLANS gives each apartment their own private connection to the router, while DHCP snooping will still allow LAN gaming and file sharing. Will DHCP snooping work with this kind of network topology, or does that rely on the network being in a proper hub-and-spoke-configuration? I am not sure if there are different levels of DHCP snooping - say like expensive Cisco switches will do anything, but inexpensive ones like TP-Link, D-Link or Netgear will only do it in certain topologies? And will basic VLAN support be good enough for this topology? I guess even cheap managed switches can tag traffic from each port with it’s own VLAN tag, but when the next switch in the daisy chain receives the packet on it’s “downlink” port, wouldn’t it strip or replace the VLAN tag with it’s own trunk-tag (or whatever the name is for the backbone traffic). Money is tight, and I don’t think we can afford professional grade Cisco (I have been campaigning for this for years), so I’d love some advice on which solution has the best support on low-end network equipment and if there are some specific models that are recommended? For instance low-end HP switches or even budget brands like TP-Link, D-Link etc. If I have overlooked another way to solve this problem it is due to my lack of knowledge. :)

  • Installing ImageMagick on Mac OSX 10.6

    - by Russell C.
    I just got a new Mac and am trying to setup a local Perl development environment. I'm using MAMP but also need the ImageMagick perl module installed in order to do some of the photo processing our scripts require. I tried installing ImageMagick manually but ran into some issues and after reading online a lot of people reported having issues going this route. The general consensus was to install it using MacPorts instead so I went ahead and installed MacPorts. Unfortunately, MacPorts can't seem to install it successfully either. Here is the command I'm using to try to install ImageMagick: sudo port install p5-perlmagick And here are all the errors reported during install: ---> Computing dependencies for p5-perlmagick ---> Building p5-perlmagick Error: Target org.macports.build returned: shell command " cd "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_perl_p5-perlmagick/work/PerlMagick-6.32" && /usr/bin/make -j2 all " returned error 2 Command output: Magick.xs:10918: error: 'struct Methods' has no member named 'exception' Magick.xs:10918: error: request for member 'severity' in something not a structure or union Magick.xs:10918: error: 'ErrorException' undeclared (first use in this function) Magick.xs:10919: error: 'struct Methods' has no member named 'exception' Magick.xs:10920: warning: implicit declaration of function 'GetImageException' Magick.xs:10922: error: 'struct PackageInfo' has no member named 'image_info' Magick.xs:10922: error: 'struct Methods' has no member named 'adjoin' Magick.xs:10929: error: request for member 'severity' in something not a structure or union Magick.xs:10929: error: 'UndefinedException' undeclared (first use in this function) Magick.xs:10929: error: request for member 'severity' in something not a structure or union Magick.xs:10929: error: request for member 'reason' in something not a structure or union Magick.xs:10929: error: request for member 'severity' in something not a structure or union Magick.xs:10929: error: request for member 'reason' in something not a structure or union Magick.xs:10929: warning: pointer/integer type mismatch in conditional expression Magick.xs:10929: error: request for member 'description' in something not a structure or union Magick.xs:10929: error: request for member 'description' in something not a structure or union Magick.xs:10929: error: request for member 'severity' in something not a structure or union Magick.xs:10929: error: request for member 'description' in something not a structure or union Magick.xs:10929: warning: pointer/integer type mismatch in conditional expression Magick.xs:10929: error: request for member 'description' in something not a structure or union Magick.xs:10929: warning: passing argument 2 of 'Perl_sv_catpv' from incompatible pointer type Magick.xs:10929: warning: unused variable 'message' Magick.xs:10856: warning: unused variable 'filename' Magick.c:10784: warning: unused variable 'ref' Magick.c:10777: warning: unused variable 'ix' Magick.xs: In function 'boot_Image__Magick': Magick.xs:2122: warning: implicit declaration of function 'InitializeMagick' Magick.xs:2123: warning: implicit declaration of function 'SetWarningHandler' Magick.xs:2124: warning: implicit declaration of function 'SetErrorHandler' make: *** [Magick.o] Error 1 Error: Status 1 encountered during processing. Before reporting a bug, first run the command again with the -d flag to get complete output. I have no idea what the problem might be or how to go about successfully installing ImageMagick. I'd appreciate any help & advice that someone out there that has done this successfully might be able to provide. Thanks in advance!

  • Layer 3 switch routing

    - by Yoshiwaan
    I need help moving over to using our layer 3 switch as the inter vlan routing device rather than our cisco router. I've mostly got it working but I've got stuck near the end and need some advice (I think I just need a bit of education on the subject really). Cur I have a Dell PowerConnect 7048 connecting to a Cisco 1841 router. I've got a few key excerpts from the configs to provide the key information. On the powerconnect I have the following: ip routing ip default-gateway 172.31.14.1 ip route 0.0.0.0 0.0.0.0 172.31.14.1 253 ! interface vlan 1 ip address 172.31.14.254 255.255.255.0 exit interface vlan 2 ip address 172.31.19.254 255.255.255.0 exit interface vlan 4 ip address 172.31.16.254 255.255.255.0 ! interface Gi1/0/1 description 'Link to L7Router01' switchport mode trunk switchport trunk allowed vlan except 3,7-4093 exit ! and on the Cisco the following: interface FastEthernet0/0 ip address 172.31.14.1 255.255.255.0 ip nat inside ip virtual-reassembly ! interface FastEthernet0/0.2 description Accounts VLAN encapsulation dot1Q 2 ip address 172.31.19.1 255.255.255.0 ip nat inside ip virtual-reassembly ! interface FastEthernet0/0.4 description Voice VLAN encapsulation dot1Q 4 ip address 172.31.16.1 255.255.255.0 ip nat inside ip virtual-reassembly ! So what I'm doing is moving clients over so that their default gateway is a 172.31.x.254 address rather than a 172.31.x.1 address. This works great for inter-vlan routing, I have no issues with this. The switch can also access the router no worries, and users on the 172.31.14.0/24 network can access all interfaces and sub-interfaces on the router, including 172.31.14.1. They can also access all of the interfaces that the router connects off to, no worries there. The problem I have is that users on the 172.31.16.0/24 and 172.31.19.0/24 subnets cannot access either 172.31.14.1 or any of the subnets the router connects to. They can, however, connect to BOTH of the sub interfaces on the router from either subnet. What am I missing here? Why can't the vlans connect to the non-sub interface on the router? Are tagged packets being sent to this interface?

  • URL Rewriting Problem

    I'm trying to rewrite my URL's subdomain. http://username.domain.com will show content of http://www.domain.com/user.php?u=username but URL stay as http://username.domain.com .

  • What are some fast methods for navigating to frequently used folders in Windows 7?

    - by fostandy
    (This is a followup question from my previous question.) In windows XP I used to be able to quickly navigate to frequently used folders by making use of the 'Favorites' menu item and the hotkey behaviour. In certain conditions it could be set up so that getting to a particular folder was as easy as alt-a x (and without a file explorer window open it was as fast as win-e alt-a x). I am struggling to get anywhere near this speed in Windows 7 and would like to solicit advice from others regarding fast folder navigation to see if I am missing any methods. My current way to navigate quickly is basically move hand to mouse move cursor to navigation pane/pain. scroll all the way to the top (because normally I the panel is focused on whatever deep directory structure I am already in). sift through my 50+ favorites to get the one I want, or click a link to a folder that contains further links in some sort of 'pseudo-tree' functionality. select it. This is slower than my previous method by upwards of an order of magnitude. There are a couple of things I've contemplated: add expandable folders, not just direct links, to the favorites menu. add expandable folders, not just direct links, to the start menu. add links of my favorite folders to a submenu of the start menu so that they come up when I search them. They do but this still rather cumbersome started using 7stacks - url here (I cannot link the url directly due to lack of reputation but http://www.alastria.com/index.php?p=software-7s). This is about the closest I've gotten to some sort of compact, customizeable, easy to access, tree based navigation structure. How do you power users quickly navigate to your favorite folders? Are there keyboard shortcuts I am missing? Can someone recommend other apps or addon or extensions that can achieve this sort of functionality? The Current solution (thanks to the answers below) I am going to use is a combination of Autohotkey and 7stacks - autohotkey to launch 7stacks, 7stacks with the 'menu' stack type for fast, key-enabled navigation to folders organised in a tree structure. This solves about 90% of the issue, the only issues are (note that these are really minor, I am really splitting hairs more than anything here) Can't use this for existing folder navigation (ie already have a explorer window open, want to go to another directory) A bit more cumbersome to add/remove entries to compared to xp favorites. A little slower than xp favorites. Whatever. I'm happy. Thanks guys. I think the answer is a split to John T and Kelbizzle - I've elected to give the answer to John T and +1 to Kelbizzle as I had already mentioned 7stacks.

  • Nginx $scheme doesn't always work while using SSL for one specific page

    - by jjiceman
    I read and followed this question in order to configure nginx to force SSL for one page (admin.php for XenForo), and it is working well for a few of the site administrators but is not for myself. I was wondering if anyone has any advice on how to improve this configuration: ... ssl_certificate example.net.crt; ssl_certificate_key example.key; server { listen 80 default; listen 443 ssl; server_name www.example.net example.net; access_log /srv/www/example.net/logs/access.log; error_log /srv/www/example.net/logs/error.log; root /srv/www/example.net/public_html; index index.php index.html; location / { if ( $scheme = https ){ rewrite ^ http://example.net$request_uri? permanent; } try_files $uri $uri/ /index.php?$uri&$args; index index.php index.html; } location ^~ /admin.php { if ( $scheme = http ) { rewrite ^ https://example.net$request_uri? permanent; } try_files $uri /index.php; include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param HTTPS on; } location ~ \.php$ { try_files $uri /index.php; include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param HTTPS off; } } ... It seems that the extra information in the location ^~ /admin.php block is unecessary, does anyone know of an easy way to avoid duplicate code? Without it it skips the php block and just returns the php files. Currently it applies https correctly in Firefox when I navigate to admin.php. In Chrome, it downloads the admin.php page. When returning to the non-https website in Firefox, it does not correctly return to http but stays as SSL. Like I said earlier, this only happens for me, the other admins can go back and forth without a problem. Is this an issue on my end that I can fix? And does anyone know of any ways I could reduce duplicate configuration options in the configuration? Thanks in advance!

  • Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem

    - by zchads
    Router reconfigures PC's and they can no longer access the internet via hardwired connection to DSL Modem. Hardware Information: Buffalo Wireless Router/access point, Model: WZR-HP-G300NH-AP DSL Modem: Generic (actually not sure of manufacture). Service Provider: TOT (Thailand) Laptop-1: Windows XP and Belkin PCMIA Network Card Laptop-2: Windows XP unknown network card & Wifi Laptop-3: Windows 7 unknown network card & Wifi Outline of Problem/actions taken: After a recent power failure the router and laptop-1 connected to router were no longer able to access the internet. Actions taken to try and recover internet access: Using Laptop-1 tried to configure Router with PPPoe settings using software from Router Manufacture. During the installation process a Timeout error was experienced, unable to connect to WAN. Used Internet Explorer to communicate directly with Router using IP address. Changed settings to use PPPoe settings given by ISP. Router was not able to communicate with Internet. Repeated steps 1-4 again with no success. Reset Router and DSL modem. Repeated steps 1-4 again still no success. Tried connecting Laptop-1 directly to DSL to gain access to internet to research problem. No Network connection with DSL could be established…connection would be established for a second and then be lost and didn’t appear long enough to actually connect to DSL. Replugged LAN back into Router and connection was regained with laptop-1. Replugged Laptop-1 directly into DSL and again unable to establish network connection. Uninstalled network card and all of its drivers on Laptop-1. Reinstalled network card and drivers and tried connecting directly to DSL. Still unable to make network connection. Plugged DSL into Laptop-3 and Internet connection was established. Being Laptop-3 does not have a CD-Rom, Laptop-2 was tried to connect to the router. With Laptop-2 steps 1-7 ended up being repeated without success. Tried plugging Laptop-2 directly into DSL and again no network connection could be established. Using Laptop-3 with a direct connection to DSL downloaded latest Router FW. Installed router FW using Laptop-1. Tired the installation process again without success. Being desperate reinstalled OS on Laptop-1 still not success. Tried using “ipconfig” with router to see what was going on without success. With laptop-1 connected to DSL went through the “ipconfig /…” inputs to see if anything made a difference. Being the network card was not able to make a connection this provide very little information “media disconnected”. So now I have a router and two laptops which are unable to connect to the internet and sure could use some advice/help.

  • Gateway GT5220 Boot/POST Failure

    - by John Rudy
    I have a Gateway GT5220 I'm troubleshooting. It is, in fact, the machine I just gave my father for his birthday a couple months ago. (Prior to that, it was my home PC. My home PC is now the MacBook on which I'm writing this.) Before going any further, I suspect that the answer will be, "It's worse than that, it's dead, Jim, it's dead, Jim, it's dead, Jim." At least, mobo and/or CPU. The initial symptoms were as follows: Turn on power All fans fire up (thus making it so I can't hear if the hard drive is spinning or not, nor are my hands sensitive enough anymore to feel it) No LEDs remained lit on the front panel. (Initially, the hard drive indicator flashed briefly.) No beep, no video, no nothing. Following some advice I found here, I tried to "drain the stored power." After following those steps, the new symptoms were: Turn on power All fans fire up The front panel LEDs remained lit! After about 20, maybe 30 seconds, we had video! Sort of. We got to the Gateway splash/POST screen, which appeared thoroughly corrupted. How corrupted? Well, I imagine it's what a POST screen would look like after reading the wrong passage out of the Necronomicon: It stayed there. I gave it at least 5, maybe 6 minutes, and it didn't move. So I shut her down, started her up again, and now (this is where we currently stand, symptomatically) we have this: Turn on power All fans fire up The front panel LEDs remain lit No video, no beep, no nothing. I'm a software guy; haven't done real hardware troubleshooting in years. My gut tells me that the mobo and/or CPU is fried, and unfortunately my gut didn't get to be as big as it is being wrong all the time. :( In addition to the link above, I have read all of the following (trying to save you some LMGTFY trouble): Gateway Support POST Error Messages and Handling About a zillion (useless) POST beep code sites A kioskea.net post indicating that most likely we're at what I consider "total loss" (mobo and/or CPU) My questions: Are there any conditions other than mobo/CPU that could cause symptoms like these? Is it worth my time to try the next hardware troubleshooting step?(IE, remove all non-critical hardware from the machine, try to boot, systematically replace one by one until we find the failing component) Which mobos will fit in the Gateway GT5220 case (with rear ports correctly aligned)? (Why this is not a dupe: I wouldn't have posted this question if it hadn't been for the funkadelic possessed video display on the one occasion we got video out. I think that justified this not being an exact dupe. Of course, if the community overrules, I will understand.)

  • What are some of the best wireless routers for a price-conscious home power-user?

    - by Alain
    I'm extremely dissatisfied with the 'popular' choice for routers in homes and small offices. They are expensive (upwards of 60$), lack a great deal of useful configuration options, and seem to need to be restarted quite often. (Linksys comes to mind). I've been on the market for a good router lately, and slowly collecting a set of requirements I feel good routers should meet. Maximum number of TCP/IP connections. - This isn't something I see any routers advertise, but in terms of supporting torrent applications, I've been screwed by routers that support less than 20 here. From what I understand a fairly standard number is 200, but there are not so expensive routers that support thousands. Router configuration menu - Most have standard menu's that let you set up basic things like your wireless network encryption settings, uPnP, and maybe even DMZ (demilitarized zones). An absolute requirement for me, however, are routers with good enough firmware to support: Explicit Port forwarding Assigning static local ips to specific mac addresses, or at least Port forwarding by MAC address Port, IP and MAC filtering Dynamic DNS service for home users who want to set up a server but have a dynamic IP Traffic shaping (ideally) - giving priority to packets from certain machines or over certain ports. Strong wireless signal - If getting a reliable signal requires me to be so close to the router that I can connect an Ethernet cable, it's not good enough. As many Ethernet ports as possible. - Because I want to be able to switch from console gaming to PC gaming without visiting my router. So far, the best thing I've stumbled upon (in the bargain bin at staples) was a 20$ retail plus router. It was meant to be the cheapest alternative until I could find something better to purchase online, but I was actually blown away by the firmware capabilities. It supports defining reserved bandwidth for certain network traffic, dynamic DNS, reserving local IPs for specific MAC addresses, etc. At 2 am when my roommate is killing our Internet with their torrents, I can limit their bandwidth without outright blacklisting them. I have, however, met serious limitations when it comes to network traffic between local machines. It claims a 300Mbps connection, but I have trouble streaming videos from my PC to my console or other laptops wirelessly. It has a meltdown and needs to be reset once in a while (no more than a couple times a month), and it's got a 200 connection limit. There 4 Ethernet ports in the back but I'm pretty sure the first doesn't work. So some great answers to this question would be: Any metrics you use to compare routers, and requirements you have for new candidates. The best routers you've found for supporting home servers, file management systems, high volume torrent traffic, good price/feature ratio, etc. Good configuration advice (aside from 'use Ethernet whenever possible') Thanks for your feedback and experiences!

  • High Jitter in NTP and poll value never goes above 128

    - by Aseem
    I have a lot of servers syncing to the same NTP servers (4). Not every server is in the same LAN. Some are 3 hops away from the NTP servers and some are 6 hops away. On couple of servers I see that the poll value never touches the 1024 mark and the jitter value is in double digits. Could it be due to the system hardware? These are windows servers (physical) and require as accurate time as possible. Please advice what I should do.

  • shell script to start multiple Java programs from a directory at boot

    - by zcourts
    I'm not sure if this is the best approach to this, It's my first time doing all of this (including writing shell scripts). OS: Centos My problem: I want to start multiple shell scripts at boot. One of the shell scripts is to start my own services and 3 others are for third party services. The shell script to start my own services will be looking for jar files. I currently have two services (will change), written in Java. All services are named under convention prefix-service-servicename What I've done: I created the following directory structure /home/username/scripts init.sh boot/ boot/startthirdprtyservice1.sh boot/startthirdprtyservice2.sh boot/startthirdprtyservice3.sh boot/startmyservices.sh /home/username/services prefix-lib-libraryname.jar prefix-lib-libraryname.jar prefix-service-servicename.jar prefix-service-servicename.jar prefix-service-servicename.jar In init.sh I have the following: #!/bin/sh #This scripts run all executable scripts in the boot directory at boot #done by adding this script to the file /etc/rc.d/rc.local #nohup #run-parts /home/username/scripts/boot/* #for each file in the boot dir... # ignore the HUP (hangup) signal for s in ./boot/*;do if [ -x $s ]; then echo "Starting $s" nohup $s & fi done echo "Done starting bootup scripts " echo "\n" In the script boot/startmyservices.sh I have #!/bin/sh fnmatch () { case "$2" in $1) return 0 ;; esac ; return 1 ; } ##sub strin to match for SUBSTRING="prefix-service" for s in /home/username/services/*;do if [ -x $s ]; then #match service in the filename , i.e. only services are started if fnmatch "$SUBSTRING" "$s" ; then echo "Starting $s " nohup $s & fi fi done echo "Done starting Services" echo "\n" Finally: Usually you can stick a program in /etc/rc.d/rc.local for it to be run at boot but I don't think this works in this case, or rather I don't know what to put in there I've just learnt how to do this by reading up a bit so I'm not sure its particularly the best thing to do so any advice is appreciated. When I run init.sh nohup.out contains Starting the thirdparty daemon... thirdparty started... .... but nothing from myservices.sh and my Java services aren't running I'm not sure where to start debugging or what could be going wrong. Edit Found some issues and got it to work, used -x instead of -n to check if the string is none zero, needed the sub string check to also be if [[ $s = $SUBSTRING ]] ; then and this last one was just stupid, missing java -jar in front of $s Still unsure of how to get init.sh to run at boot though

  • Deploying Django App with Nginx, Apache, mod_wsgi

    - by JCWong
    I have a django app which can run locally using the standard development environment. I want to now move this to EC2 for production. The django documentation suggests running with apache and mod_wsgi, and using nginx for loading static files. I am running Ubuntu 12.04 on an Ec2 box. My Django app, "ddt", contains a subdirectory "apache" with ddt.wsgi import os, sys apache_configuration= os.path.dirname(__file__) project = os.path.dirname(apache_configuration) workspace = os.path.dirname(project) sys.path.append(workspace) sys.path.append('/usr/lib/python2.7/site-packages/django/') sys.path.append('/home/jeffrey/www/ddt/') os.environ['DJANGO_SETTINGS_MODULE'] = 'ddt.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() I have mod_wsgi installed from apt. My apache/httpd.conf contains NameVirtualHost *:8080 WSGIScriptAlias / /home/jeffrey/www/ddt/apache/ddt.wsgi WSGIPythonPath /home/jeffrey/www/ddt <Directory /home/jeffrey/www/ddt/apache/> <Files ddt.wsgi> Order deny,allow Allow from all </Files> </Directory> Under apache2/sites-enabled <VirtualHost *:8080> ServerName www.mysite.com ServerAlias mysite.com <Directory /home/jeffrey/www/ddt/apache/> Order deny,allow Allow from all </Directory> LogLevel warn ErrorLog /home/jeffrey/www/ddt/logs/apache_error.log CustomLog /home/jeffrey/www/ddt/logs/apache_access.log combined WSGIDaemonProcess datadriventrading.com user=www-data group=www-data threads=25 WSGIProcessGroup datadriventrading.com WSGIScriptAlias / /home/jeffrey/www/ddt/apache/ddt.wsgi </VirtualHost> If I am correct, these 3 files above should correctly allow my django app to run on port 8080. I have the following nginx/proxy.conf file proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; Under nginx/sites-enabled server { listen 80; server_name www.mysite.com mysite.com; access_log /home/jeffrey/www/ddt/logs/nginx_access.log; error_log /home/jeffrey/www/ddt/logs/nginx_error.log; location / { proxy_pass http://127.0.0.1:8080; include /etc/nginx/proxy.conf; } location /media/ { root /home/jeffrey/www/ddt/; } } If I am correct these two files should setup nginx to take requests on the HTTP port 80, but then direct requests to apache which is running the django app on port 8080. If i go to mysite.com, all I see is Welcome to Nginx! Any advice for how to debug this?

  • Performance of ClearCase servers on VMs?

    - by Garen
    Where I work, we are in need of upgrading our ClearCase servers and it's been proposed that we move them into a new (yet-to-be-deployed) VMmare system. In the past I've not noticed a significant problem with performance with most applications when running in VMs, but given that ClearCase "speed" (i.e. dynamic-view response times) is so latency sensitive I am concerned that this will not be a good idea. VMWare has numerous white-papers detailing performance related issues based on network traffic patterns that re-inforces my hypothesis, but nothing particularly concrete for this particular use case that I can see. What I can find are various forum posts online, but which are somewhat dated, e.g.: ClearCase clients are supported on VMWare, but not for performance issues. I would never put a production server on VM. It will work but will be slower. The more complex the slower it gets. accessing or building from a local snapshot view will be the fastest, building in a remote VM stored dynamic view using clearmake will be painful..... VMWare is best used for test environments (via http://www.cmcrossroads.com/forums?func=view&catid=31&id=44094&limit=10&start=10) and: VMware + ClearCase = works but SLUGGISH!!!!!! (windows)(not for production environment) My company tried to mandate that all new apps or app upgrades needed to be on/moved VMware instances. The VMware instance could not handle the demands of ClearCase. (come to find out that I was sharing a box with a database server) Will you know what else would be on that box besides ClearCase? Karl (via http://www.cmcrossroads.com/forums?func=view&id=44094&catid=31) and: ... are still finding we can't get the performance using dynamic views to below 2.5 times that of a physical machine. Interestingly, speaking to a few people with much VMWare experience and indeed from running builds, we are finding that typically, VMWare doesn't take that much longer for most applications and about 10-20% longer has been quoted. (via http://www.cmcrossroads.com/forums?func=view&catid=31&id=44094&limit=10&start=10) Which brings me to the more direct question: Does anyone have any more recent experience with ClearCase servers on VMware (if not any specific, relevant performance advice)?

  • Signup with email authentication, only 30% are activated?

    - by mysqllearner
    I have a website which let users to sign up. The signup process including sending "activation email", click link to activate account. The first two weeks was fine. Out of around 2000 users, 1800 users are activated. After that, the activated users drop drastically, to about 30%. Example: 1000 users signup, only 300 were activated. At first, I found the problem is because the email could not be reach to ymail, msn and gmail users. (Most of my subscribers are Ymail (yahoo), hotmail/msn(live) and gmail (gmail)). I tried signup using ymail and hotmail, but i didnt get any activation email. I contacted yahoo and msn, eventually my email can go through now. However, my signup statistic still showing, the activated users are only about 30%, which very confuse me. I contact my hosting company, ask them the whitelist my IP. And they did it. I need your advice/help on following questions: How to check where the problem lies? Is the email not delivered? User receive email but didnt click the activation link? I am using php mail funstion. and this is my headers: $headers = 'MIME-Version: 1.0' . "\r\n"; $headers .= 'Content-type: text/html; charset=UTF-8' . "\r\n"; $headers .= 'From: Admin <[email protected]>' . "\r\n"; $headers .= 'Return-Receipt-To: Bounce <[email protected]>' . "\r\n"; $headers .= 'Reply-To: Admin <[email protected]>' . "\r\n"; $return_path = "[email protected]"; Is there anything wrong with the headers? What can I do to improve my registration/signup activation process?

  • I just restarted Apache and now the server is down

    - by James
    I am pretty terrified right now. I'm scared I'm going to get a call in a couple minutes from a hundred people saying the website doesn't work. I was at the terminal changing some configuration files when I went to restart the server to update the .conf files with this command: /etc/init.d/apache2 graceful After I ran that, none of the websites work and I have no idea what to do. There are about 100 errors I am getting according to the log files. They all begin with "PHP Notice" and most relate to "use of undefined constant" Also, I just spoke with a coworker, describing what I did, and he noticed that there are two installations of apache on the server and that I restarted the one that we don't use. This is what the error log says (assuming it's the correct error log): [Wed Jan 05 11:52:06 2011] [notice] Graceful restart requested, doing restart Warning: DocumentRoot [/u/apps/staging/antetr/current/public/] does not exist [Wed Jan 05 11:52:08 2011] [warn] NameVirtualHost *:80 has no VirtualHosts (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs (2)No such file or directory: apache2: could not open error log file /u/apps/production/madfilmdash/current/log/apache-error.log.

Unable to open logs (2)No such file or directory: apache2: could not open error log file /u/apps/production/madfilmdash/current/log/apache-error.log. Unable to open logs FINAL UPDATE: Ok, I fixed it. The problem was (as you experts facepalming probably know) that it couldn't access an error log in the directory I was working in. I created an empty error log file and tried the restart command again and now all the sites are back up... Though my original problem is still there.. Thanks to all those who offered advice, it really helped and let me breathe for a moment.

    After installing a new OS with newer version of samba, I'm having trouble accessing my shares. I can browse to the specific share, but only to the top level. As best I can tell from the logs, it seems the "force user" in the samba config isn't sticking beyond the initial connection. Details below. I installed a new version of CentOS on my storage server. My old CentOS (4?)install had samba version 3.0.33, new CentOS is using 3.5.10. No domain/AD involved ... just home workgroup. no real security... just some shares hidden & some defined as read-only. here's my config: [global] workgroup = WORKGROUP server string = Samba Server Version %v netbios name = luna security = share # logs split per machine log file = /var/log/samba/log.%m log level = 2 # max 50KB per log file, then rotate max log size = 50 winbind use default domain = Yes [strge] comment = please path = /storage browseable = yes read only = no force user = windowsguest force group = users guest ok = yes So... the problem I'm running into is that the 'force user' only seems to hold for the initial connection & I see all the top level folders fine. When I drill into a folder I get access denied - which appears to be due to my windows user info being sent (trys to authenticate xuser - a non-existant user to samba, so maps to nobody & fails). Here's the smb error msg: [2012/11/29 14:30:27.326195, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [xuser] -> [xuser] FAILED with error NT_STATUS_NO_SUCH_USER [2012/11/29 14:30:27.326251, 2] auth/auth.c:314(check_ntlm_password) check_ntlm_password: Authentication for user [nobody] -> [nobody] FAILED with error NT_STATUS_NO_SUCH_USER Most of the top level directories are 755, some 777. Either way, can not access them. If I do a chown -R windowsguest.users ... no change... but if I do a chmod -R to 777 or 755 they become browsable... but still can't create files (even for 777 ones). Not sure what role it plays if any... but had to recreate the user windowsguest under the new os install, uid & gid match old user. Seems the main issue as far as I can tell is that samba isn't maintaining the 'force user' - but I could be wildly off base. Client OS is win7 pro x64. Thanks for any suggestions or advice!

  • I just restarted Apache and now the server is down

    - by James
    I am pretty terrified right now. I'm scared I'm going to get a call in a couple minutes from a hundred people saying the website doesn't work. I was at the terminal changing some configuration files when I went to restart the server to update the .conf files with this command: /etc/init.d/apache2 graceful After I ran that, none of the websites work and I have no idea what to do. There are about 100 errors I am getting according to the log files. They all begin with "PHP Notice" and most relate to "use of undefined constant" Also, I just spoke with a coworker, describing what I did, and he noticed that there are two installations of apache on the server and that I restarted the one that we don't use. This is what the error log says (assuming it's the correct error log): [Wed Jan 05 11:52:06 2011] [notice] Graceful restart requested, doing restart Warning: DocumentRoot [/u/apps/staging/antetr/current/public/] does not exist [Wed Jan 05 11:52:08 2011] [warn] NameVirtualHost *:80 has no VirtualHosts (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs (2)No such file or directory: apache2: could not open error log file /u/apps/production/madfilmdash/current/log/apache-error.log.

Unable to open logs (2)No such file or directory: apache2: could not open error log file /u/apps/production/madfilmdash/current/log/apache-error.log. Unable to open logs FINAL UPDATE: Ok, I fixed it. The problem was (as you experts facepalming probably know) that it couldn't access an error log in the directory I was working in. I created an empty error log file and tried the restart command again and now all the sites are back up... Though my original problem is still there.. Thanks to all those who offered advice, it really helped and let me breathe for a moment.

  • BIND split-view DNS config problem

    - by organicveggie
    We have two DNS servers: one external server controlled by our ISP and one internal server controlled by us. I'd like internal requests for foo.example.com to map to 192.168.100.5 and external requests continue to map to 1.2.3.4, so I'm trying to configure a view in bind. Unfortunately, bind fails when I attempt to reload the configuration. I'm sure I'm missing something simple, but I can't figure out what it is. options { directory "/var/cache/bind"; forwarders { 8.8.8.8; 8.8.4.4; }; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; zone "." { type hint; file "/etc/bind/db.root"; }; zone "localhost" { type master; file "/etc/bind/db.local"; }; zone "127.in-addr.arpa" { type master; file "/etc/bind/db.127"; }; zone "0.in-addr.arpa" { type master; file "/etc/bind/db.0"; }; zone "255.in-addr.arpa" { type master; file "/etc/bind/db.255"; }; view "internal" { zone "example.com" { type master; notify no; file "/etc/bind/db.example.com"; }; }; zone "example.corp" { type master; file "/etc/bind/db.example.corp"; }; zone "100.168.192.in-addr.arpa" { type master; notify no; file "/etc/bind/db.192"; }; I have excluded the entries in the view for allow-recursion and recursion in an attempt to simplify the configuration. If I remove the view and just load the example.com zone directly, it works fine. Any advice on what I might be missing?

  • 403 forbidden while submitting a POST request with image data via iPhone application

    - by binnyb
    I am creating an iOS application which allows users to send image/text data to my webserver via a POST request. I am successfully sending POSTS to the server when image data is not included in the request. Any time i POST with image data the server spits back a 403 forbidden. I have tried adding the following to the .htaccess file in the directory of the script with no luck: Options +Indexes FollowSymLinks +ExecCGI Order allow,deny Allow from all web browsers and Android devices can successfully POST with image data to the script, the only device which cannot is the iPhone. POSTING with data to other hosting providers works as expected - it is just this host(ipowerweb.com). i noticed that when i try to POST to ANY script on the server with data returns a 403 forbidden. another note: i can successfully post to another server that is hosted by ipowerweb, but mine cant seem to handle it. My host has tried to resolve the issue but cannot, and they have marked it on their end as "resolved", so no more help from them. I wish to keep this host as moving would be a pain - i will change hosts as a last resort, so please help me! Why am i getting this 403 forbidden error only when i submit data via my iPhone application? How can i resolve the issue so i can successfully POST data? any advice on what i can do would be greatly appreciated. edit: as request, here are the response headers: { Connection = close; "Content-Length" = 217; "Content-Type" = "text/html; charset=iso-8859-1"; Date = "Wed, 12 Jan 2011 19:11:19 GMT"; Server = "Apache/2"; } edit: as request here are the request headers(oops): { "Accept-Encoding" = gzip; "Content-Length" = 5781; "Content-Type" = "multipart/form-data; charset=utf-8; boundary=0xKhTmLbOuNdArY"; "User-Agent" = "YeahIAteThat 1.0 (iPhone; iPhone OS 4.2.1; en_US)"; }

  • Postmaster uses excessive CPU and Disk Writes

    - by wolfcastle
    using PostgreSQL 9.1.2 I'm seeing excessive CPU usage and large amounts of writes to disk from postmaster tasks. This happens even while my application is doing almost nothing (10s of inserts per MINUTE). There are a reasonable number of connections open however. I've been trying to determine what in my application is causing this. I'm pretty newb with postgresql, and haven't gotten anywhere so far. I've turned on some logging options in my config file, and looked at connections in the pg_stat_activity table, but they are all idle. Yet each connection consumes ~ 50% CPU, and is writing ~15M/s to disk (reading nothing). I'm basically using the stock postgresql.conf with very little tweaks. I'd appreciate any advice or pointers on what I can do to track this down. Here is a sample of what top/iotop is showing me: Cpu(s): 18.9%us, 14.4%sy, 0.0%ni, 53.4%id, 11.8%wa, 0.0%hi, 1.5%si, 0.0%st Mem: 32865916k total, 7263720k used, 25602196k free, 575608k buffers Swap: 16777208k total, 0k used, 16777208k free, 4464212k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17057 postgres 20 0 236m 33m 13m R 45.0 0.1 73:48.78 postmaster 17188 postgres 20 0 219m 15m 11m R 42.3 0.0 61:45.57 postmaster 17963 postgres 20 0 219m 16m 11m R 42.3 0.1 27:15.01 postmaster 17084 postgres 20 0 219m 15m 11m S 41.7 0.0 63:13.64 postmaster 17964 postgres 20 0 219m 17m 12m R 41.7 0.1 27:23.28 postmaster 18688 postgres 20 0 219m 15m 11m R 41.3 0.0 63:46.81 postmaster 17088 postgres 20 0 226m 24m 12m R 41.0 0.1 64:39.63 postmaster 24767 postgres 20 0 219m 17m 12m R 41.0 0.1 24:39.24 postmaster 18660 postgres 20 0 219m 14m 9.9m S 40.7 0.0 60:51.52 postmaster 18664 postgres 20 0 218m 15m 11m S 40.7 0.0 61:39.61 postmaster 17962 postgres 20 0 222m 19m 11m S 40.3 0.1 11:48.79 postmaster 18671 postgres 20 0 219m 14m 9m S 39.4 0.0 60:53.21 postmaster 26168 postgres 20 0 219m 15m 10m S 38.4 0.0 59:04.55 postmaster Total DISK READ: 0.00 B/s | Total DISK WRITE: 195.97 M/s TID PRIO USER DISK READ DISK WRITE SWAPIN IO> COMMAND 17962 be/4 postgres 0.00 B/s 14.83 M/s 0.00 % 0.25 % postgres: aggw aggw [local] idle 17084 be/4 postgres 0.00 B/s 15.53 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 17963 be/4 postgres 0.00 B/s 15.00 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 17188 be/4 postgres 0.00 B/s 14.80 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 17964 be/4 postgres 0.00 B/s 15.50 M/s 0.00 % 0.24 % postgres: aggw aggw [local] idle 18664 be/4 postgres 0.00 B/s 15.13 M/s 0.00 % 0.23 % postgres: aggw aggw [local] idle 17088 be/4 postgres 0.00 B/s 14.71 M/s 0.00 % 0.13 % postgres: aggw aggw [local] idle 18688 be/4 postgres 0.00 B/s 14.72 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 24767 be/4 postgres 0.00 B/s 14.93 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 18671 be/4 postgres 0.00 B/s 16.14 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 17057 be/4 postgres 0.00 B/s 13.58 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 26168 be/4 postgres 0.00 B/s 15.50 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle 18660 be/4 postgres 0.00 B/s 15.85 M/s 0.00 % 0.00 % postgres: aggw aggw [local] idle
