  • DHCP not working after NetBIOS over TCP/IP disabled

    - by user27515
    I want to disable the "NetBIOS over TCP/IP" device in the device manager to free port 445. But after doing that my Internet stops working. I'm connected to a WLan router using DHCP on WinXP, and it is stuck forever in the "acquire network address" step. Why does it misbehave like that? I don't need NetBIOS!

  • Nginx Password Protect Directory Downloads Source Code

    - by Pamela
    I'm trying to password protect a WordPress login page on my Nginx server. When I navigate to http://www.example.com/wp-login.php, this brings up the "Authentication Required" prompt (not the WordPress login page) for a username and password. However, when I input the correct credentials, it downloads the PHP source code (wp-login.php) instead of showing the WordPress login page. Permission for my htpasswd file is set to 644. Here are the directives in question within the server block of my website's configuration file: location ^~ /wp-login.php { auth_basic "Restricted Area"; auth_basic_user_file htpasswd; } Alternately, here are the entire contents of my configuration file (including the above four lines): server { listen *:80; server_name domain.com www.domain.com; root /var/www/domain.com/web; index index.html index.htm index.php index.cgi index.pl index.xhtml; error_log /var/log/ispconfig/httpd/domain.com/error.log; access_log /var/log/ispconfig/httpd/domain.com/access.log combine$ location ~ /\. { deny all; access_log off; log_not_found off; } location = /favicon.ico { log_not_found off; access_log off; } location = /robots.txt { allow all; log_not_found off; access_log off; } location /stats/ { index index.html index.php; auth_basic "Members Only"; auth_basic_user_file /var/www/web/stats/.htp$ } location ^~ /awstats-icon { alias /usr/share/awstats/icon; } location ~ \.php$ { try_files /b371b8bbf0b595046a2ef9ac5309a1c0.htm @php; } location @php { try_files $uri =404; include /etc/nginx/fastcgi_params; fastcgi_pass unix:/var/lib/php5-fpm/web11.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_intercept_errors on; } location / { try_files $uri $uri/ /index.php?$args; client_max_body_size 64M; } location ^~ /wp-login.php { auth_basic "Restricted Area"; auth_basic_user_file htpasswd; } } If it makes any difference, I'm using Ubuntu 14.04.1 LTS with Nginx 1.4.6 and ISPConfig 3.0.5.4p3.

  • Where can I buy a Stereo audio to 3.5mm adapter?

    - by iftrue
    I need a stereo (6.33mm) to PC audio (3.5mm) adapter, and I'd like it to have an inch or two of cable so that yanking the connector doesn't break the audio port the 3.5mm is plugged into. I used to own one of these, but I lost the adapter. Where can I buy something like this online? I can only find solid adapters or 25' cables.

  • Need to Connect 2 HDMI between Onboard and Add-In GPUs - What's the consequences?

    - by jmalais
    If i plug a second hdmi cable into my onboard video output (my dedicated add-in only has one hdmi port) will it use my video card or the onboard for that display? Also, what is the difference in quality between HDMI and DVI? I do have a DVI to HDMI adapter and cable that I could use alternatively if the above is not in my best interest. This is a gaming related question as I will be gaming off the two displays, hopefully in the highest of quality.

  • USB ports causing Wireless and Mobile Phone tethering drop out

    - by chrolli
    I have a problem with my USB ports and I can't seem to pinpoint the problem. I'm hoping that I can get some idea as to how to troubleshoot my problem. Problem description: I recently bought a USB Wireless Adapter in order to connect my Desktop PC to the WLAN. The dongle keeps dropping off connection regularly on average once a minute. And the connection is slow. What I've tried: I installed a network scanner to determine signal strength. The PC/adapter combo is getting about 70% signal strength. I have a laptop that has an internal Wireless adapter. I moved the laptop near the location of the PC. The signal strength was above 90%. I installed the USB adapter on the laptop. I placed the laptop near the location of the PC. The signal strength was above 80%. And there is no drop out issue. I've isolated the problem to be on the PC. I used internet tethering on my mobile phone in order to test the USB ports. I get the same problem, themobile phone keeps dropping in and out. I plugged the adapter and phone on all USB ports, and it is still dropping out on all ports. I've isolated the problem to be the Motherboard, USB hub. I updated the BIOS, and USB driver. Still dropping out. I noticed that when I used the mobile phone tethering method, the phone (iphone 5) is guarenteed to drop out and does not appear to charge if I jiggle the the 8-pin connector on the base of the phone. If I push the pin tightly on the phone, the phone starts charging, as soon as I let go, it stops and drops out from the PC. This is strange because this doesn't happen when it is plugged to the powerboard. Which means that the 8 pin connector is fine. I'm not sure what the problem is. I assume that it is to do with the USB ports not supplying enough power which in turn causes the devices to intermittently drop out. The reason I say this is because the USB cable works fine when plugged into a powerboard with enough power supplied to the phone. Only when it is plugged into the USB port on the PC, does it drop out. My motherboard is Asus P8z68-v le. My Wireless adapter is the D-link DWA131. I can't seem to find any settings in the BIOS to increase the south bridge voltage so as to supply more power to the USB ports. Although this problem only occurs when I'm trying to hook up to a device supplying internet connection. My USB HDD, Flash drives, and Mouse and Key are working fine! Any suggestions please?

  • OpenBSD pf 'match in all scrub (no-df)' causes HTTPS to be unreachable on mobile network

    - by Frank ter V.
    First of all: excuse me for my poor usage of the English language. For several years I'm experiencing problems with the 'match in all scrub (no-df)' rule in pf. I can't find out what's happening here. I'll try to be clear and simple. The pf.conf has been extremely shortened for this forum posting. Here is my pf.conf: set skip on lo0 match in all scrub (no-df) block all block in quick from urpf-failed pass in on em0 proto tcp from any to 213.125.xxx.xxx port 80 synproxy state pass in on em0 proto tcp from any to 213.125.xxx.xxx port 443 synproxy state pass out on em0 from 213.125.xxx.xxx to any modulate state HTTP and HTTPS are working fine. Until the moment a customer in France (Wanadoo DSL) couldn't view HTTPS pages! I blamed his provider and did no investigation on that problem. But then... I bought an Android Samsung Galaxy SII (Vodafone) to monitor my servers. Hours after I walked out of the telephone store: no HTTPS-connections on my server! I thought my servers were down, drove back to the office very fast. But they were up. I discovered that disabling the rule match in all scrub (no-df) solves the problem. Android phone (Vodafone NL) and Wanadoo DSL FR are now OK on HTTPS. But now I don't have any scrubbing anymore. This is not what I want. Does anyone here understand what is going on? I don't. Enabling scrubbing causes HTTPS webpages not to be loaded on SOME ISP's, but not all. In systat, I strangely DO see a state created and packets received from those ISP's... Still confused. I'm using OpenBSD 5.1/amd64 and OpenBSD 5.0/i386. I have two ISP's at my office (one DSL and one cable). Affects both. This can be reproduced quite easily. I hope someone has experience with this problem. Greetings, Frank

  • OpenVPN Clients using server's connection (with no default gateway)

  • The server rejected the session-establishment request: WCF hosted on IIS

    - by Dave Hanna
    Background: I'm working on a project where we have about a dozen distinct WCF services implemented in an IIS application, communicating over net.tcp on the default port (808), using the Microsoft Net.Tcp Port Sharing Service. I recently added a self-test method to the base class of each of these services so that I could remotely hit the service and get back a status string verifying that it was in operation. We implement this app in a ladder of environments - Development, QA, UAT, and finally production. My problem: My test program, which instantiates a connection to each service in turn and invokes the self-test method, works fine on all the environments below production. We recently moved the app to production, and I'm getting a weird error that I can't explain: On the first of the services that I hit, I get back an exception: "The server at [URL] rejected the session-establishment request". All the other services respond fine. I initially thought there was something wrong with the particular service that was failing, but I tried rearranging the list of services into a different order, and it SEEMS to always be the first service that I hit that fails. (I say SEEMS because it think once in the early iterations of testing, I saw it happen on the second service that it hit. But I haven't been able to reproduce that.) I've looked at application startup delays, and that doesn't seem to be the problem, because I can come back and run the test again as soon as it finishes - a delay of only a minute or two - and get the same error. Also, in the lower level environments, there is a start up delay of probably 30 seconds to a minute, but the result still comes back as expected. I've tried accessing the services over http from INetManager, and I get intermittent failures on all the services - a particular service will return a yellow screen of death on on invocation, then come up with the expected link to the WSDL on the next one seconds later. I'm completely at a loss to explain this behavior, or how to resolve it. I've googled the error message, and not found anything helpful. It may be a configuration issue - the production servers are newly provisioned VM's, and we may not have the config exactly right (whereas all the lower level environments have been running this and other similar apps for some time), but I have not idea what to look for. I've looked at the properties of the app pool that the app is running on and compared it to the lower level environments without finding any differences. If somebody can point me in the right direction, you would have my undying gratitude.

  • Access denied to mysql cause by invalid server hostname bind address

    - by Mark
    I cannot login to mysql using the terminal. [root@fst mysql]# mysql -h localhost -u admin -p Enter password: ERROR 1045 (28000): Access denied for user 'admin'@'localhost' (using password: YES) I am sure I have the correct password. The mysql is also running when I check status. The mysql database is also present in the directory /var/lib/mysql/. The host host.myi, host.myd and host.frm are present. By the way this a related to question on my previous problem MySQL server quit without updating PID file . Initially the problem arise when the root directory was full. To be able to login to directadmin and start mysql, I added a soft link of the /var/lib/mysql/ to /home/mysql. Since my database used up the most of the root directory. The root directory has 50Gb and /home has 1.5Gb. Somehow the /var/lib/mysql/idbdata1 is corrupted. So I move it to another location. Now, I can start the mysql server but I cannot login into it. Below are the contents from the myql logs. 121212 20:44:10 mysqld_safe mysqld from pid file /var/lib/mysql/fst.srv.net.pid ended 121212 20:44:10 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 121212 20:44:10 [Note] Plugin 'FEDERATED' is disabled. 121212 20:44:10 InnoDB: The InnoDB memory heap is disabled 121212 20:44:10 InnoDB: Mutexes and rw_locks use GCC atomic builtins 121212 20:44:10 InnoDB: Compressed tables use zlib 1.2.3 121212 20:44:10 InnoDB: Using Linux native AIO 121212 20:44:10 InnoDB: Initializing buffer pool, size = 128.0M 121212 20:44:10 InnoDB: Completed initialization of buffer pool 121212 20:44:10 InnoDB: highest supported file format is Barracuda. 121212 20:44:11 InnoDB: Waiting for the background threads to start 121212 20:44:12 InnoDB: 1.1.8 started; log sequence number 1595675 121212 20:44:12 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306 121212 20:44:12 [Note] - '0.0.0.0' resolves to '0.0.0.0'; 121212 20:44:12 [Note] Server socket created on IP: '0.0.0.0'. 121212 20:44:12 [Note] Event Scheduler: Loaded 0 events 121212 20:44:12 [Note] /usr/sbin/mysqld: ready for connections.

  • How can I connect DLNA devices through NAT?

    - by Bob
    I have a Windows 7 PC running Serviio as a DLNA server. I have a Samsung I9100G running Skifta as a DLNA renderer (client). My network topology: At the moment, I can connect and watch my videos fine if the phone is on router #2. The server is on a wired network with #2. Router #1 is 192.168.1.1, router #2 is 192.168.2.1 (192.168.1.2) and router #3 is 192.168.3.1 (192.168.1.3). In other words, each router has its own subnet, using NAT - their "modem" port is connected with a "LAN" port on the modem/router 1. What I want to do is be able to connect to the DLNA server if the renderer is connected to router #1/#3 - #1 is on the WAN side of #2, while #3 is even further separated. I'll settle for just #1 working, though. Normally, I would just forward the appropriate ports, and everything would work fine. However, (apparently) DLNA uses UPnP, which I am unfamiliar with. I tried enabling UPnP on router #2, but that did not seem not change anything. It's a Belkin F5D7230-4 6000 - there's reported issues with UPnP on F5D7230-4 7000. UPnP is already enabled on router #1 - a Billion BiPAC 7700N. I've also tried the built in DLNA renderer/server/controller on my phone, Samsung AllShare. It can see the server on router #2 and browse files, but has issues playing or downloading them. It also can't see the server on the other two networks. I'm currently using Skifta/s "local" mode. "Remote" mode requires an account, which I don't really want to create if not necessary. Is it possible too do what I'm trying to do? If no, are there workarounds? If yes, how do I do it? Is my server the issue? The renderer (client)? The router(s)? My method? I can change just about anything except the routers.

  • DisplayPort -> DVI Adapter, Active or Passive?

    - by Aren B
    I read somewhere that you only need an active adapter (usb powered) if you want resolutions greater than 1920x1200. I also heard from someone that you need it when running triple-monitor because more than two displays drains too much power. So to connect a 3rd monitor @ 1920x1200 to my video card's DisplayPort Port, do I need to spend the extra $100 and buy the active adapter?

  • Issue with VMWare vSphere and NFS: re occurring apd state

    - by Bastian N.
    I am experiencing issues with VMWare vSphere 5.1 and NFS storage on 2 different setups, which result in an "All Path Down" state for the NFS shares. This first happened once or twice a day, but lately it occurs much more frequent, as specially when Acronis Backup jobs are running. Setup 1 (Production): 2 ESXi 5.1 hosts (Essentials Plus) + OpenFiler with NFS as storage Setup 2 (Lab): 1 ESXi 5.1 host + Ubuntu 12.04 LTS with NFS as storage Here is an example from the vmkernel.log: 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 248: APD Timer started for ident [987c2dd0-02658e1e] 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 395: Device or filesystem with identifier [987c2dd0-02658e1e] has entered the All Paths Down state. 2013-05-28T08:07:33.479Z cpu0:2054)StorageApdHandler: 846: APD Start for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4cf28 3 2013-05-28T08:07:37.485Z cpu0:2052)NFSLock: 610: Stop accessing fd 0x410007e4d0e8 3 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 277: APD Timer killed for ident [987c2dd0-02658e1e] 2013-05-28T08:07:41.280Z cpu1:2049)StorageApdHandler: 402: Device or filesystem with identifier [987c2dd0-02658e1e] has exited the All Paths Down state. 2013-05-28T08:07:41.281Z cpu1:2049)StorageApdHandler: 902: APD Exit for ident [987c2dd0-02658e1e]! 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4d0e8 again 2013-05-28T08:07:52.300Z cpu1:3679)NFSLock: 570: Start accessing fd 0x410007e4cf28 again As long as the issue occurred once or twice a day it really wasn't a problem, but now this issue has impact on the VMs. The VMs get slow or even hang, resulting in a reset through vCenter in the production environment. I searched the web extensively and asked in forums, but till now nobody was able to help me. Based on blog posts and VMWare KB articles I tried the following NFS settings: Net.TcpipHeapSize = 32 Net.TcpipHeapMax = 128 NFS.HartbeatFrequency = 12 NFS.HartbeatMaxFailures = 10 NFS.HartbeatTimeout = 5 NFS.MaxQueueDepth = 64 Instead of NFS.MaxQueueDepth = 64 I already tried other settings like NFS.MaxQueueDepth = 32 or even NFS.MaxQueueDepth = 1. Unfortunately without any luck. It would be great if someone could help me on this issue. It is really annoying. Thanks in advance for all the help. [UPDATE] As I explained in the comment below, here is the network setup: On the production setup the NFS traffic is bound to a separate VLAN with ID 20. I am using a HP 1810 24 Port Switch. The OpenFiler system is connected to the VLAN with 4 Intel GbE NICs with dynamic LACP. The ESXis both have 4 Intel GbE NICs using 2 static LACP trunks containing 2 NICs each. One pair is connected to the regular LAN and the other one to the VLAN 20. And here is a screenshot of the vSwitch: Switch configuration: Port configuration: On the lab setup its a single Intel NIC on each side without VLAN, but with different IP subnet.

  • Why does a wired network slow down with user increase?

    - by Ed Briscoe
    If you had a wired network, 20 PCs hooked up to a 100 Mbit/sec switch (same onboard ethernet port speed) and you were just sending some test data round. What is the technical explanation as to why 20 machines sending test data around this network to each other is slower than one to one? I mean I know a busy network means it's slower but I'm really trying to understand some more technical details. Thanks for any help

  • Packet dropped even when firewall is turned off in windows server 2008

    - by LightX
    We have a windows 2008 server and lately we have started seeing a lot of 5152 Events logged in the server (Windows Filtering Platform blocked a packet). We have an inbound rule configured to allow connections to the port which was working fine earlier. I'm not sure what changed lately. But this doesn't make any sense. The packet is dropped even when windows firewall is disabled. What am I missing?
