• Why won't dhclient use the static IP I'm telling it to request?

• Media Center setup won't complete for watching TV

  - by Robert

  I have a problem watching TV in Media Center. The TV constantly pauses 1/2 second then plays 1 second, pauses 1/2 second, plays 1 second - it is constant and does not vary. This problem occurs on all channels, live or recorded. The bottom 5th of the screen is solid green. I know the problem is Media Center because I can use Pinnacle's TVCenterPro to watch TV and there is no skipping/pausing (and not green on bottom). I was using cable, and switched to DirecTV (satellite). Trying to do "Set up TV signal" in Media Center seems to be what broke it. I get an error "IR Hardware not detected." I can use the remote to "try again" - so the IR hardware works fine (Media Center's remote/sensor). I tried plugging the IR Blaster into both ports, and I tried a different USB port for the IR receiver. I can't complete the setup. Media Center was playing TV okay (with the new DirecTV) before I tried to run setup. (I ran setup to try to do recording with Media Center.) Hardware/Software: Pinnacle PCTV 800i HD PCI card (coax cable from DirecTV tuner), ATI Radeon HD 3200 Graphics, Windows XP SP3 Media Center Edition, AMD Athlon Dual Core 2.5 GHz, 1.75 GB RAM.

• Need for explanation: NetBIOS over TCP/IP on VMware network adapter disturbs access to network share

  - by gyrolf

  (Moved here from StackOverflow) Some time ago nearly all workstations in our team (Windows XP SP2) exhibited intermittend but frequent delays when accessing shares on the network. Typically the first access to a share which hadn't been accessed for some time resulted in a nearly frozen workstation for up to 30 seconds. Then everything started working fine again. Using TCPView from Sysinternals I saw that during this delays there was a connection to the netbios-ssn port on the file server which was in state SYN_SENT. First try: Disable NetBIOS over TCP/IP for the intranet network adapter. Problem solved, but I didn't like to manipulate our centrally managed network configuration for the intranet. Second try: Disable NetBIOS over TCP/IP only for the VMWare network adapter (VMNet1 used for host only communications). Problem solved again! My questions: Why does NetBIOS over TCP/IP on one network adapter disturb NetBIOS over TCP/IP on another network adapter? Is this problem specific to VMWare network adapters? Has anybody else seen this phenomen? Additional information: VMWare Workstation version 6.0.3 At the time I started seriously analysing the problem it was no more possible to find out what had been changed to our systems at the time the problems started.

• Firefox crash on first load on Ubuntu Linux on older Dell Laptop

  - by Ira Baxter

  I've had a Dell Latitude laptop since about 2000 without managing to destroy it. A month ago the Windows 2000 system on it did something stupid to its file system and Windows was completely lost. No point in reinstalling Windows 2000, so I installed an Ubuntu Linux on the laptop. Everything seems normal (installed, rebooted, I can log in, run GnuChess, poke about). ... but ... when I attempt to launch Firefox from the top bar menu icon, I get a bunch of disk activity, the whirling cursor icon goes round a bit and then everything stops: disk, icon, mouse. Literally nothing happens for 5 minutes. Ubuntu is dead, as far as I can tell. A reboot, and I can repeat this reliably. So on the face of it, everything works but Firefox. That seems really strange. The only odd thing about this system when Firefox is booting is that while it has an Ethernet port (that worked fine under Windows), it isn't actually plugged into an Ethernet. As this is the first Firefox boot since the Ubuntu install, maybe Firefox mishandles Internet access? Why would that crash Ubuntu? (I need to go try the obvious experiment of plugging it in).

• Nginx infinite redirect loop

  Why is http://compassionpit.com/blog/ going through an infinite redirect loop? Here's my nginx conf file.

• SSL Returning Blank Page, No Catalina Errors

  - by Mr.Peabody

  This is my second, maybe third, time configuring SSL with Tomcat. Earlier I had created a self signed, which worked, and now using my signed is proving fruitless. I am using Tomcat, operating from the Amazon Linux API. When using the signed cert/keystore, my server is starting normally without errors. However, when trying to navigate to the domain it is giving me an "ERR_SSL_VERSION_OR_CIPHER_MISMATCH" error. My server.xml file looks as follows: <Connector port="8443" maxHttpHeaderSize="8192" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" disableUploadTimeout="true" acceptCount="100" scheme="https" secure="true" SSLEnabled="true" clientAuth="false" sslProtocol="TLS" keystoreFile="/home/ec2-user/.keystore/starchild.jks" keystorePass="d6b5385812252f180b961aa3630df504" /> It couldn't hurt to also mention that I'm using a wildcard certificate. Please let me know if anything looks amiss! EDIT: After looking more into this, I've determined there may be nothing is wrong with the Server.xml, or the listening ports. This is becoming more of an actual certificate error, as the curl request is giving me this error: curl: (35) Unknown SSL protocol error in connection to jira.mywebsite.com:-9824 Though, I can't seem to figure out what the "-9824" is. When comparing this curl to another similar setup (using the same Wildcard Certificate) it's turning up the full handshake, which is to be expected. I believe this is now between the protocol/cypher set default on JIRA servers.

• Karmic iptables missing kernel moduyles on OpenVZ container

  - by luison

  After an unsuccessful p2v migration of my Ubuntu server to an OpenVZ container which I am stack with I thought I would give a try to a reinstall based on a clean OpenVZ template for Ubuntu 9.10 (from the OpenVZ wiki) When I try to load my iptables rules on the VM machine I've been getting errors which I believe are related to kernel modules not being loaded on the VM from the /vz/XXX.conf template model. I've been testing with a few post I've found but I was stack with the error: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Could not load /lib/modules/2.6.24-10-pve/modules.dep: No such file or directory iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I read about the template not loading all iptables modules so I added modules to the XXX.conf of the VZ virtual machine like this: IPTABLES="ip_tables iptable_filter iptable_mangle ipt_limit ipt_multiport ipt_tos ipt_TOS ipt_REJECT ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_LOG ipt_length ip_conntrack ip_conntrack_ftp ip_conntrack_irc ipt_conntrack ipt_state ipt_helper iptable_nat ip_nat_ftp ip_nat_irc" As the error remained I read that I should build dependencies again on the virtual machine: depmod -a but this returned an error: WARNING: Couldn't open directory /lib/modules/2.6.24-10-pve: No such file or directory FATAL: Could not open /lib/modules/2.6.24-10-pve/modules.dep.temp for writing: No such file or directory So I read again about creating the directory empty and redoing "depmod -a" it. I now don't get the dependancies error but get this and I don't have a clue how to proceed: WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. FATAL: Module ip_tables not found. iptables-restore v1.4.4: iptables-restore: unable to initialize table 'raw' Error occurred at line: 2 Try `iptables-restore -h' or 'iptables-restore --help' for more information. I understand that iptables rules have to be different on the VM machine and perhaps some of the rules we are trying to apply (from our physical server) are not compatible but these are just source IP and destination port checks that I would like to be able to have available . I've heard that on the CentOS template there are no issues with this, so I understand is to do with VM config. Any help would be greatly appreciated.

• Seagate 3TB ST3000DM001 hard drive not recognized by Linux, causes fdisk to hang

  - by MountainX

  I'm running Kubuntu 12.04. I have a brand new, never used Seagate 3TB ST3000DM001 hard drive. It's an internal drive. I installed it in a USB enclosure. When I connect it to my PC, nothing happens automatically. When I run sudo fdisk -l, fdisk hangs (without reporting this drive) until I disconnect this drive from the USB port. blkid won't report it either. I tried connecting it to both USB 2.0 and USB 3.0 ports on my PC. I got the same result either way. I tried two different USB enclosures with the same result. If I take the same drive, same enclosure and connect it to a Windows 7 laptop, it is recognized automatically as a USB mass storage device. I want to format the drive (probably ext4) and copy files to it. I have another drive, also in a USB enclosure, that is connected via USB 3.0 to this PC and it works fine. It's a 2.0 TB Samsung HDD. I plan to copy files from the 2TB to the 3TB drive, once I get this issue resolved. My motherboard is an Asus Asus P8B WS LGA1155/ Intel C206/ Quad CrossFireX/ SATA3&USB3.0/ A&2GbE/ ATX. What is the resolution?

• Cannot Resolve Host Or Access Website Through Router

  - by Boris_yo

  This is weird. I am on Windows XP with Edimax BR 6204Wg. I have 3 devices - 2 laptops and 1 smartphone. 1st laptop and smartphone are connected through WiFi to router and 2nd laptop is connected through LAN to router. Before firmware upgrade i did not try to access website but after firmware upgrade to latest version: http://www.edimax.eu/en/support_detail.php?pd_id=11&pl1_id=3#02 i had problems resolving host, pinging, tracerting and accessing website. Sometimes ping and tracert work but i cannot access website and sometimes i can access website but ping and tracert do not work. Weird? I downgraded to previous version and no changes. If i can no longer access that website through Internet Explorer, i can access it in Firefox. I tried deleting cookies, clearing cache and that seem not make difference. Switching LAN port did not make difference. When i disconnect router and connect laptop through LAN to internet modem, everything is normal. I tried resetting router, resetting to factory default settings and all did not help. At the moment i can access website on laptop connected through LAN from Firefox and Internet Explorer, but on my smartphone i can access website only with Opera but not with built-in browser and Skyfire. UPDATE: I just could only access with Internet Explorer but not with other browsers on my PC. Minutes later i could access with all browsers. But on smartphone i could only access with Opera and not with other browsers. I am confused. I also determined that sometimes i can access and sometimes can't. What is also weird is that when ping and tracert cannot resolve host, i still am able to access website.

• The USB mouse sticks in Windows 7 after automatic attempt to fix the boot

  - by chelder

  Avast Antivirus asked me to delete a probable virus and to restart to perform a checking. I had to stop the checking at the middle of the procedure as I needed the computer. It was imposible to turn off the computer pushing the power button (as it entered in suspension mode, no matter how long I kept pushed the power button). I removed the battery as the only way to restart the computer. Windows 7 said that there is a problem to iniziate Windows. Windows 7 tried to fix the problem without success. Windows 7 started after that though. Everything is OK but the USB mouse. The USB mouse sticks and freezes each couple of seconds more or less. The tactile mouse (PS2) works well. I googled for solutions but the posible solutions didn't work for me. What happened? How could I fix it without formatting and reinstalling everything? UPDATE: this is what I did: Change the mouse from one usb port to another Test another mouse Set the number of cores of the CPU manually with msconfig Power management: not disable usb ports Check hard disk errors

• dhclient requests filling memory?

  - by shanethehat

  Dammit Jim, I'm a web developer, not a sys admin. With that out of the way, my client's has a CentOS server (6.2) that is only serving a single Magento site (and the associated MySQL server) and it is frequently running out of memory, despite the site only currently being open to 5 users. I'm investigating the logs to try to figure out why the memory usage is so high, but I don't really know what I'm looking at. It seems that there are a lot of entries in /var/log/messages concerning DHCP requests, approximately one every 15 seconds, that look like this: Apr 7 14:23:06 s15940039 dhclient[815]: DHCPREQUEST on eth0 to 172.30.102.85 port 67 (xid=0x6b5cd2a7) Is this normal? I don't see anything else in here that I don't recognise, but then I'm not sure I'd know the problem if I did see it. 4 days ago the server ran out of memory completely and locked up, requiring a restart. The DHCP messages did not start up again for 23 hours, but then carried on as before. I have read this question which describes the same issue, but in my case a fresh DHCP lease does not ever seem to be issued. Is this something I should push back to the hosting provider, or have I not yet found the source of the memory problem?

• Can I get ethernet out of my Verizon FIOS set-top box?

  - by Tom Hughes

  Setup: my home network is long & skinny, and the FIOS-connected router is all the way at one of the apartment. At the other end, far away (and a floor higher) is my HD TV, which gets a cable-TV signal from a Verizon set-top box that is coax-connected back to the FIOS on-premises equipment. Wi-Fi won't work, the apartment is too stretched out, with old, thick walls and floors. Goal: I think there are three ways to get ethernet back to where the HD TV is: 1) run a cable! this isn't crazy but isn't cheap either (my building won't let me do it, it involves hiring an electrician because the cable would run partly through the public hallway ceiling) 2) split the coax near the TV and put in... a MoCA device? 3) somehow tease the set-top box, which has an RJ-11 (ethernet) port on the back, to give me network access. Question: any other choices? and, is one choice better than the others? #3 is by far the most desirable because it would involve the least wiring -- but I can't find any resources to help make it happen. #2 is a bit scary, I don't want to degrade service to the TV or anywhere else for that matter.

• How to serve pages through multiple frameworks/template engines efficiently

  - by Leftium

  I would like to render a file that has both PHP tags and Web2Py tags mixed together. To do this, I would like the web server to pass the file through Web2Py, then PHP. I found a method to call PHP from Web2py via Python (based on this method for running PHP on top of django), but this method loses the benefits of any server optimizations from mod_php or FastCGI like caching and multi-threaded operation. A new process is created for each PHP request, which is very slow. Is there a better way to efficiently render pages with both Web2Py(Python) and PHP tags in the same file? Note I am not looking for methods of serving PHP-only and Web2Py-only files from the same server/domain. I prefer solutions for Apache2 or Cherokee. I'm open to using other web servers, though. Background info: I prefer to develop in Web2Py, but we have this pre-existing system written in PHP. I would like to augment the PHP system with some of Web2Py's features like auth authentication/user management and the T() internationalization object. Also it would make it much easier to port the PHP project to Web2Py if it could be done piecemeal. Since the PHP project consists of many files, it would greatly help if they did not need modification.

• Performance: Nginx SSL slowness or just SSL slowness in general?

  - by Mauvis Ledford

  I have an Amazon Web Services setup with an Apache instance behind Nginx with Nginx handling SSL and serving everything but the .php pages. In my ApacheBench tests I'm seeing this for my most expensive API call (which cache via Memcached): 100 concurrent calls to API call (http): 115ms (median) 260ms (max) 100 concurrent calls to API call (https): 6.1s (median) 11.9s (max) I've done a bit of research, disabled the most expensive SSL ciphers and enabled SSL caching (I know it doesn't help in this particular test.) Can you tell me why my SSL is taking so long? I've set up a massive EC2 server with 8CPUs and even applying consistent load to it only brings it up to 50% total CPU. I have 8 Nginx workers set and a bunch of Apache. Currently this whole setup is on one EC2 box but I plan to split it up and load balance it. There have been a few questions on this topic but none of those answers (disable expensive ciphers, cache ssl, seem to do anything.)

• Configuring https access on HP A5120 Switch

  - by GerryEgan

  I am trying to configure HTTPS management on a HP a5120 switch running Version 5.20.99, Release 2215 and not having much luck. I have followed the manual by creating an SSL policy first and then enabling the HTTPS server with the SSL policy: ssl server-policy sslpol ip https ssl-server-policy sslpol ip https enable When I try and log onto the switch with Google Chrome I get the following error: Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. When I look this up I have found references to errors due to TLS being used in SSL. I can find no way to specify the SSL version in the server policy. The manual has a configuration example that uses MSCEP to retrieve a certificate but in Windows 2008 R2 that feature is only available in Enterprise and Datacentre editions which I don't have. I have SSH configured and it is using a locally generated certificate so I'm not sure if I can use that but I'd like to if possible.

• Active FTP client blocked on Windows XP

  - by Ian Hannah

  Summary We have a FTP server (running in active mode). We have an FTP client which is connecting to the server, carrying out a task and then closing the connection. The FTP Client can perform this operation on multiple threads. Problem We have a situation where customers are experiencing occasional failures to carry out operations on a FTP connection. The actual connection has been made to the server but when the server attempts to return data on the data port if fails. Observations We have a simple test FTP client which is running two separate threads. Each thread is performing a recursive listing of files from a root directory. With the firewall running on the client machine the hang happens within a few minutes. If the firewall is turned off on the client machine, the test application seems to run correctly. This does point to a potential firewall issue. However, with the firewall on we can list files on our company FTP server without any issues. If the simple test FTP client runs a single thread then we do not experience any problems whether or not the firewall is turned on. We have another simple test FTP client which was running 4 threads (with each opening a new FTP connection, doing a directory listing and closing the FTP connection as fast as possible) overnight with the firewall turned off. With the firewall turned on it fails in a short space of time. The confusing thing is that if the test FTP client and the FTP server are run on the same machine the failure occurs even though the firewall is turned off. This means that the problem may not be firewall related. Any help with what this could be would be much appreciated. Thanks Ian

• Bypass proxy authentication [closed]

  - by Diego Queiroz

  My scenario: My network has a proxy that requires interative authentication. When I access any URL, an username and password is requested to enable navigation. I do have a valid username/password (this means I have permissions to access external content). I do not have access to the proxy server (any change to the proxy server is not an option). What I need: I need to bypass the interative authentication process and make it an automated authentication process. What I do NOT need/want: I do not need/want to hack the network. I do not need/want to access unauthorized content. In other words, I just need to find a way to "save" my password in the computer (security is not a problem) to allow application that does not support this kind of interative authentication to access the internet (like non-browser software that also uses HTTP port). My guess: My guess is to develop a new proxy server that will run in the local machine (eg, a proxy for the network proxy). This proxy server will access my network proxy, authenticate and forward the content. Of course this is a last resort. I prefer to not need to develop a proxy server. Does someone know other solution? (any operating system)

• ssh connection operation timed out using rsync

  - by Mark Molina

  I use rsync to backup my remote server on my local device but when I combine it with a cron job my ssh times out. Just to be clear, the data is stored on a remote server and I want it stored on my local server. The backup request must be sent from my local server to the remote server. The command for backup up the data is working when I just type it in terminal like this: rsync -chavzP --stats USERNAME@IPADDRES: PATH_TO_BACKUP LOCAL_PATH_TO_BACKUP but when I combine it with a cron job like this: 10 11 * * * rsync -chavzP --stats USERNAME@IP_ADDRESS: PATH_TO_BACKUP LOCAL_PATH_TO_BACKUP the ssh connection times out. When the cronjob executes it send a mail to the root user with the output like this: From local.xx.xx.xx Tue Jul 2 11:20:17 2013 X-Original-To: username Delivered-To: [email protected] From: [email protected] (Cron Daemon) To: [email protected] Subject: Cron <username@server> rsync -chavzP --stats USERNAME@IPADDRES: PATH_TO_BACKUP LOCAL_PATH_TO_BACKUP X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=username> X-Cron-Env: <USER=username> X-Cron-Env: <HOME=/Users/username> Date: Tue, 2 Jul 2013 11:20:17 +0200 (CEST) ssh: connect to host IP_ADDRESS port XX: Operation timed out rsync: connection unexpectedly closed (0 bytes received so far) [receiver] rsync error: unexplained error (code 255) at /SourceCache/rsync/rsync-42/rsync/io.c(452) [receiver=2.6.9] So the rsync command is working when just typed in terminal but not when used by a cronjob. Can anybody explain this?

• Using GUI ftp on Win7 and Vista without additional software

  - by Stephen Jones

  Goal: provide a 'no-software' method for 'less technical' users to access password protect ftp location from Win7 and Vista (existing approach for WinXP works). 'No software' method to mean without installing additional software (e.g. FileZilla, WinSCP) - the solution is supplied to external non-technical users. WinXP (works): Using Windows Explorer, WinXP supports non-technical ftp access by pasting: ftp://username:[email protected] into the address bar. The remote ftp site's files / directory structure becomes available and can be copied to / from easily (in the style of local file copy / paste) by a 'less technical' user. Win7 / Vista (doesn't work): Pasting the same URL into the Windows Explorer on Win7 or Vista causes an error: An error occurred opening that folder on the FTP server. Make sure you have permission to access that folder. Details: The connection with the server was reset. Notes: a) The same username/password/server typed from the (DOS) command line achieves access to the server, but this is a more 'technical' solution than desired. I am looking for a WinXP equivalent solution. b) Under 'Control Panel' / 'Internet options' / 'Advanced' tab - the boxes for 'Enable FTP folder view' and 'Use Passive FTP' are ticked (enabled) c) Adding an inbound firewall rule for local port 20 (TCP) was attempted with no difference in results (i.e. failure)

• Setup Version Control on Dreamweaver

  - by John Isaacks

  I have a win computer on the Network called WIN2K8FS1 I have TortoiseSVN on a win computer and when I go to checkout a repository with Tortoise it asks me for the URL of the repository. I put in: file://WIN2K8FS1/Media/SVN_repo And it creates the working copy. I am trying to setup Dreamweaver CS5 to work with subversion. I create a new site and I go to the Version Control tab and it asks for a lot if info. First is Access. I choose Subversion since that is the only option Second is Protocol. Not sure which I need so I go with HTTP? Third is Server Address. I am assuming this is the name of the computer with the repository so I put in \\WIN2K8FS1\ Fourth is Repository Path. I put in /Media/SVN_repo Fifth is Port which I leave default to 80 Then it asks for user name and password. I never set one up for anything so I put in my domain username and password. I click test and it tells me: Server and project are not accessible! I am not sure what I am doing wrong. I am not the server admin but I did create the repository and have access to it via Tortoise. So I am not sure what I am doing wrong in Dreamweaver.
