• Solaris 10 invalid ARP requests from 0.0.0.0? Link up/down every hour or 2

  - by JWD

  The guys at the data center where I'm hosting a server running Solaris 10 are telling me that my server is making a lot of invalid arp requests. This is an example of a portion of what was sent to me from the logs (with Mac addresses and IP addresses changed). [mymacaddress]/0.0.0.0/0000.0000.0000/[myipaddress]/[Datestamp]) It's being logged every hour. I don't see anything in the arp tables (arp -a) or routing tables (netstat -r) and I don't see anything relating to 0.0.0.0 when snoping the arp requests. The only place I see any reference to 0.0.0.0 is if I do netstat -a for the SCTP SCTP: Local Address Remote Address Swind Send-Q Rwind Recv-Q StrsI/O State ------------------------------- ------------------------------- ------ ------ ------ ------ ------- ----------- 0.0.0.0 0.0.0.0 0 0 102400 0 32/32 CLOSED But not really sure what that means. Doesn't seem like I can disable SCTP. There are some tunable SCTP parameters but it's not something I'm familiar with. Do I have to add changes to /etc/system? Looks like sctp_heartbeat_interval might be what I need to change? If it makes any difference, I have a few solaris zones running on this server, each with their own IP address on a virtual interface. eth0:0, eth0:1, etc. Does anyone have any idea what might be causing this and how to stop it? I think the switch I'm connected to doesn't like it and momentarily drops the connection. Is there anyway to at least block those requests using ipfilter or something else? Update: This was happening more frequently but now it seems to be happening roughly every hour or every two hours. It's not consistent. I tried setting setting the link speed and duplex to match the switch port and that seemed to make it stop happening for a few hours but then it started again.

• PostgreSQL pg_hba.conf with "password" auth wouldn't work with PHP pg_connect?

  - by tftd

  I've recently experimented with the settings in pg_hba.conf. I read the PostgreSQL documentation and I though that the "password" auth method is what I want. There are many people that have access to the server PostgreSQL is working on so I don't want the "trust" method. So I changed it. But then PHP stopped working with the database. The message I get is "Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL: password authentication failed for user "myuser" in /my/path/to/connection/class.php on line 35". It is kind of strange because I can connect via phppgadmin without any problems and also I can connect from my home computer with psql - again without any problems. This is my pg_hba.conf: # TYPE DATABASE USER CIDR-ADDRESS METHOD # "local" is for Unix domain socket connections only local all all password # IPv4 local connections: host all all 127.0.0.1/32 password # IPv6 local connections: host all all ::1/128 password The connection string I'm using with pg_conenct is: $connect_string = "host=localhost port=5432 dbname=mydbname user=auser password=apassword"; $dbConnection = pg_connect($connection_string); Does anybody know why is this happening ? Did I misconfigured something ?

• Private staff network within public network

  - by pianohacker

  I'm the sysadmin at a small public library. Since I got here a few years ago, I've been trying to set up the network in a secure and simple way. Security is a little tricky; the staff and patron networks need to be separated, for security reasons. Even if I further isolated the public wireless, I'd still rather not trust the security of our public computers. However, the two networks also need to communicate; even if I set up enough VMs so they didn't share any servers, they need to use the same two printers at the very least. Currently, I'm solving this with some jerry-rigged commodity equipment. The patron network, linked together by switches, has a Windows server connected to it for DNS and DHCP and a DSL modem for a gateway. Also on the patron network is the WAN side of a Linksys router. This router is the "top" of the staff network, and has the same Windows server connected on a different port, providing DNS and DHCP, and another, faster DSL modem (separate connections are very useful, especially as we heavily depend on some cloud-hosted software). tl;dr: We have a public network, and a NATed staff network within it. My question is; is this really the best way to do this? The right equipment would likely make my job easier, but anything with more than four ports and even rudimentary management quickly becomes a heavy hit on our budget. (My original question was about an ungodly frustrating DHCP routing issue, but I thought I'd ask whether my network was broken rather than asking about the DHCP problem and being told my network was broken.)

• Require and Includes not Functioning Nginx Fpm/FastCGI

  - by Vince Kronlein

  I've split up my FPM pools so that php will run under each individual user and set the routing correctly in my vhost.conf files to pass the proper port number. But I must have something incorrect in my environment because on this new domain I set up, require, require_once, include, include_once do not function, or rather, they may not be getting passed up to the interpreter to be rendered as php. Since I already have a Wordpress install on this server that runs perfectly, I'm pretty sure the error is in my server block for nginx. server { server_name www.domain.com; rewrite ^(.*) http://domain.com$1 permanent; } server { listen 80; server_name domain.com; client_max_body_size 500M; index index.php index.html index.htm; root /home/username/public_html; location / { try_files $uri $uri/ index.php; } location ~ \.php$ { if (!-e $request_filename) { rewrite ^(.*)$ /index.php?name=$1 break; } fastcgi_pass 127.0.0.1:9002; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } location ~ /\.ht { deny all; } } The problem I'm finding I think is that there are dynamic calls to the doc root index file, while all calls to anything within a sub-folder should be routed as normal ie: NOT passed to index.php. I can't seem to find the right mix here. It should run like so: domain.com/cindy (file doesn't exist) --> index.php?name=$1 domain.com/admin/anyfile.php (files DO exist) --> admin/anyfile.php?$args

• Diagnosing Logon Audit Failure event log entries

  - by Scott Mitchell

  I help a client manage a website that is run on a dedicated web server at a hosting company. Recently, we noticed that over the last two weeks there have been tens of thousands of Audit Failure entries in the Security Event Log with Task Category of Logon - these have been coming in about every two seconds, but interesting stopped altogether as of two days ago. In general, the event description looks like the following: An account failed to log on. Subject: Security ID: SYSTEM Account Name: ...The Hosting Account... Account Domain: ...The Domain... Logon ID: 0x3e7 Logon Type: 10 Account For Which Logon Failed: Security ID: NULL SID Account Name: david Account Domain: ...The Domain... Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x154c Caller Process Name: C:\Windows\System32\winlogon.exe Network Information: Workstation Name: ...The Domain... Source Network Address: 173.231.24.18 Source Port: 1605 The value in the Account Name field differs. Above you see "david" but there are ones with "john", "console", "sys", and even ones like "support83423" and whatnot. The Logon Type field indicates that the logon attempt was a remote interactive attempt via Terminal Services or Remote Desktop. My presumption is that these are some brute force attacks attempting to guess username/password combinations in order to log into our dedicated server. Are these presumptions correct? Are these types of attacks pretty common? Is there a way to help stop these types of attacks? We need to be able to access the desktop via Remote Desktop so simply turning off that service is not feasible. Thanks

• Live Screencast under Linux

  I was having some difficulty with running a Live Screencast under Linux.

• NIC reordering on RHEL5/CentOS 5

  - by ewwhite

  I have an HP ProLiant DL360 G6 containing two onboard NICs as well as an HP NC375T (NetXen NX3031 chipset) 4-port PCIe card. The system was running with eth0 and eth1 belonging to the onboard NICs and eth2-eth5 on the NetXen card. I recently rebuilt the server and from the kickstart process onward, the NICs were reordered such that the onboard NICs became eth4 and eth5, while the NetXen card took over eth0-eth3. I've had some experiences in the past where I tied NICs to specific interfaces via changes in the ifcfg-ethX config files, but this is the first time I've ever seen an add-in card take over eth0 from the motherboard's interfaces. This impacted my kickstart scripts, so: 1). How can I ensure that the onboard NICs take precedence in the kickstart arrangement. 2). What is the most consistent way to maintain that ordering through repeated reboots, kernel changes (e.g. going from a RHEL mainline kernel to a RHEL MRG realtime kernel), etc. 3). What is the interaction between the /etc/modprobe.conf module/NIC definitions, the /etc/sysconfig/network-scripts/ifcfg-ethX and the /etc/modprobe.d/blacklist functions in this context?

• Amazon EC2 instance missing Network Interface

  - by Sergiks

  I am running Linux on a t1.micro instance at Amazon EC2. Once I noticed bruteforce ssh login attemtps from a certain IP, after litle Googling I issued the two following commands (other ip): iptables -A INPUT -s 202.54.20.22 -j DROP iptables -A OUTPUT -d 202.54.20.22 -j DROP Either this, or maybe some other actions like yum upgrade perhaps, caused the follwing fiasco: after rebooting the server, it came up without the Network Interface! I only can connect to it through AWS Management Console JAVA ssh client - via local 10.x.x.x address. Console's Attach Network Interface as well as Detach.. are greyed out for this instance. Network Interfaces item at the left does not offer any Subnets to choose from, to create a new N.I. Please advice, how can I recreate a Network Interface for the instance? Upd. The instance is not accessible from outside: cannot be pinged, SSH'ed or connected by HTTP on port 80. Here's the ifconfig output: eth0 Link encap:Ethernet HWaddr 12:31:39:0A:5E:06 inet addr:10.211.93.240 Bcast:10.211.93.255 Mask:255.255.255.0 inet6 addr: fe80::1031:39ff:fe0a:5e06/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1426 errors:0 dropped:0 overruns:0 frame:0 TX packets:1371 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:152085 (148.5 KiB) TX bytes:208852 (203.9 KiB) Interrupt:25 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) What is also unusual: a new micro instance I created from scratch, with no relation to the troubled one, was not pingable too.

• Monitor goes black for a few seconds

  - by privatehuff

  I have a Hanns G 28" monitor, Model # HG281D It has its issues (viewing angle sucks) but has been functional and solid, great for desktop stuff. Worked without any sign of any problems for 6-12 months. However, now the monitor "goes black" for about 2-3 seconds, almost like when you click "detect display" It does not turn off (power light does not go amber) The computer is completely unaffected and the video mode never changes when the picture returns. The computer is fully responsive and will keep playing music or taking my keypresses during the time I can't see anything. (it just happened and I kept typing, etc) It happens on multiple computers across several operating systems. (I have an 8-port iogear KVM switch that has several computers connected) But, it seems to happen only on certain computers. I have a hackintosh that does it, a windows 7 PC that does not, a lenovo laptop that does not, and my old ubuntu 8.10 box did not do it, but my new mint 8 box does do it. I've check the connections and tried changing out the power cable and the vga cable. Sometimes it won't happen for hours (or days) and sometimes it happens several times per hour. It was happening many months ago, did not happen for months, and has now started happening again. Does this make any sense? What could it be?

• Puppet variables best practice, generalise or specialise?

  - by Andrei Serdeliuc

  I'm trying to figure out which things should be in git within the puppet manifest and which should be in env vars like FACTER_my_var and use that in the manifest instead. Scenario: you are deploying 3 php apps and you've already built all the layers up to the app in other manifests (base system, php extensions, users, etc), and all that's left is installing the correct app (from an apt repo) and creating a vhost. I'm tempted to have something along the lines of: apache::vhost { $::project_hostname: priority => '10', port => '80', docroot => $::project_document_root, logroot => "/var/log/apache2/${$::project_name}", serveradmin => '[email protected]', require => Package[httpd], ssl => false, override => 'all', setenv => ["APP_KERNEL dev"] } This would run on each server, and the FACTER_project_* vars would be set on a per server basis. An obvious restriction of this would be that you can't run more than one app with this specific example. Or would you rather have project_x.pp, project_y.pp which have hardcoded paths and names?

• How to handle sh: fetch: command not found

  - by Tyler Johnson

  Okay, I'm a noobie. I know how to build and compose a website, but I have no idea what I'm doing when it comes to servers and server commands, etc. I've recently had a problem with all of my sites on our servers going down all at once and then I have to go in and reboot the server for them to come up again. At first this was annoying, but now it is becoming agonizing as it now takes 3-4 reboots for the websites to come back up. I contacted support for my hosting, but they are not being very helpful. They just keep telling me what the issue might be and basically telling me that I'm going to have to look into it and figure it out, which really isn't possible since I know nothing. Anyway, here are the things they said were possible reasons: They said I have "strange logs" in my Apache webserver log, error: sh: fetch: command not found. My php.ini memory limit is: 256M which is very high. It should be 32M or 64M. Server is reaching Max Clients, meaning we have more than 150 visitors at a time. (They supposedly "fixed" this, but the sites/server are still going down) I have some Wordpress sites with plugins getting errors like: PHP Warning: pack(): Type H: illegal hex digit G in... PHP Fatal error: Cannot use object of type stdClass as array in... PHP Fatal error: Maximum execution time of 30 seconds exceeded in... PHP Fatal error: Call to undefined function file_exists() in... PHP Parse error: syntax error, unexpected '<' I know that's a lot, but I really am at wits end and have no idea what to do now. If anyone could maybe give me some advice or point me in the right direction I would greatly appreciate it! Thanks! Oh, and here are the specs for my server: RAM: 2048MB CPU Shares: 40 Primary Disk: 50GB Data Transfer: 75GB Port Speed: 5Mbps

• How do I keep a bridge enabled on a bonded interface?

  - by jlawer

  I'm working on setting up a pair of CentOS 6.3 servers that will run a couple of KVM vms and have come across a problem setting up a bridge on a bond. I am using Mode 4 (802.3ad) bonding on a pair of stacked Dell Powerconnect 5524 switches connecting to R320 servers. There are 2 links (1 to each switch) that form a Link Aggregation Group (802.3ad / LACP bonding). On top of the bond I have VLAN Tagging. I've verified this is a problem on multiple other bonding modes so it isn't just a mode 4 issue. I am testing what happens when 1 link is dropped (ie switch dies, cable breaks, etc). If I don't have a bridge (for KVM), everything works fine, failover happens as expected. If I have the bridge enabled, it works fine until failover (unplugging a cable). When failover happens /var/log/messages shows the slave link going down, followed within a second by: kernel: br1: port 1(bond0.8) entering disabled state The thing is /proc/net/bonding/bond0 shows the link is up as expected (simply with only 1 slave instead of 2). If I plug the cable back in it recovers and brings the bridge back to an enabled state. I actually have tested this while a ping is occuring and if the timing is right a packet will actually leave the system after the link is lost, but before the disabled message occurs. This disabled state I assumed was STP, but I have disabled STP on the bridge configuration and this issue still occurs. brctl showstp br1 still shows the link as disabled when it is running without a slave. I also switched between the nics in the server (I have 2x Broadcom & 4x intel). It doesn't matter which configuration I have. Does anyone know of a way to force the bridge to stay enabled or why its detecting the bond as disabled, when it isn't?

• Looking for a host based network monitor solution

  - by Ole Martin Handeland

  Hi all! Problem So, my hosting company has a network usage graph for my dedicated server. It seems that one day earlier this month, my network usage suddenly spiked with several hundred megabytes transferred (usually it's in the tens, not hundreds). It was probably me, but i just can't be sure who or what it was. Question So my question is; does anyone know of any host based solution for monitoring network usage that would tell me the client's IP-address, the port/service he/she used? What I don't want I'm just guessing that someone will suggest i use nagios, munin, zabbix, cacti, mrtg - I've also looked at those, but a graph over network usage will not give me the answers I'm looking for. :-) Almost there I've already looked at a lot of monitoring solutions, and I've tried [ntop][http://www.ntop.org/], [darkstat][http://unix4lyfe.org/darkstat/] and others. Darkstat just didn't give me the answers. Although it listed a lot of statistics, and i could list the clients - it doesn't show me the network usage for a particular period. Ntop is by far the best I've seen so far - but i think it mostly shows current network usage, not the historical part. I could run apt-get upgrade and download a whole bunch of software, but not see it in the log afterwards.

• How important is dual-gigabit lan for a super user's home NAS?

  - by Andrew

  Long story short: I'm building my own home server based on Ubuntu with 4 drives in RAID 10. Its primary purpose will be NAS and backup. Would I be making a terrible mistake by building a NAS Server with a single Gigabit NIC? Long story long: I know the absolute max I can get out of a single Gigabit port is 125MB/s, and I want this NAS to be able to handle up to 6 computers accessing files simultaneously, with up to two of them streaming video. With Ubuntu NIC-bonding and the performance of RAID 10, I can theoretically double my throughput and achieve 250MB/s (ok, not really, but it would be faster). The drives have an average read throughput of 83.87MB/s according to Tom's Hardware. The unit itself will be based on the Chenbro ES34069-BK-180 case. With my current hardware choices, it'll have this motherboard with a Core i3 CPU and 8GB of RAM. Overkill, I know, but this server will be doing other things as well (like transcoding video). Unfortunately, the only Mini-ITX boards I can find with dual-gigabit and 6 SATA ports are Intel Atom-based, and I need more processing power than an Atom has to offer. I would love to find a board with 6 SATA ports and two Gigabit LAN ports that supports a Core i3 CPU. So far, my search has come up empty. Thus, my dilemma. Should I hold out for such a board, go with an Atom-based solution, or stick with my current single-gigabit configuration? I know there are consumer NAS units with just one gigabit interface (probably most of them), but I think I will demand a lot more from my server than the average home user. Any advice is appreciated. Thanks.

• Running phpmyadmin xampp Ubuntu 12.10

  - by Luigi Tiburzi

  I know it is a common problem and there are many solutions on the web but I'm trying everything and anything is working, I can't have phpmyadmin running on my machine. I installed XAMPP through: sudo tar xvfz ./Downloads/xampp-linux-1.8.1.tar.gz -C /opt then I did the chmod trick supposed to make an end to access issues and I change the default location to my php projects from /var/www to Dropbox/php. Then I started XAMPP in the usual way: sudo /opt/lampp/lampp start When I tried to run one of my php projects the output on the web is fine but if for example I try to write localhost on my browser I get: It works and not the usual XAMPP interface and most of all when I try to access localhost/phpmyadmin I get the login page, insert username (root) and password and I get: You don't have permission to access /phpmyadmin/index.php on this server. Apache/2.2.22 (Ubuntu) Server at localhost Port 80 I tried the Required all granted trick and some others but nothing is working. I even tried to uninstall phpmyadmin and reinstall it but this is not working too. I don't know hot to proceed. Thanks for your help.

• What is the replacement of the floppy

  - by alexanderpas

  While CD (and to an lesser extend DVD) disks have reached the price-point of the floppy, they have one significant downside, it is WORM (Write-Once Read-Many) media, allowing it to be used only one single time, and you need to be explicit in writing the data to the actual media (you need to burn it.) While CD-RW solves the "use only once" problem, it is still EWORM (Erasable Write-Once Read-Many) media, which still means you need to be explicit in writing the data to the actual media (you still need to burn it.), and also, you still need to be very explicit in erasing it. (simple delete is not possible.) Okay, we can use a CD-RW in Packet Writing mode, however the downside to that, is that this mode is not very universal, and also, not the native mode of the media. Now, while USB-sticks and SD-cards may not have the poblems of the CD, they have a whole other kind of problem: their PRICE! USB-sticks and SD cards are generally 10 to 100 times as expensive as diskettes per piece. SD-cards, in addition have an added problem, because they need a reader to operate. While it is a very standard thing, it is not default equipment on the computer like the CD drive or USB port (or historically the diskette drive). You wouldn't give out an USB stick or SD card with a 100 kB text file, not caring weither you would get it back or not. So, to recap: CD & DVD are basically WORM media. SD cards and USB sticks are relatively expensive. SD cards also needs special readers. Diskettes have a very low data-rate Diskettes have a very low storage capacity. Now, is there a media out there that solves all these problems, or is there a way to get (very) small USB sticks or SD cards for a very low price (as they're the closest thing to diskette).

• Asus K55VM usb 3.0 issue

  - by user2141481

  Good day superusers! I own the above laptop and I found out that there are some unknown and unusual issues with usb 3.0 ports. I haven't noticed anything strange until now. I got a new toshiba usb 3.0 external hdd and when I try to copy larger amount of data from my disk to the external hdd, the OS(windows 7) randomly starts ignoring the external hdd. It doesn't shut it down, it kinda just stops responding but the light on the hdd is still lit. I get an error that the files cannot be copied. I have reinstalled windows 7, installed all drivers(including intel chipset drivers of course) and the issue is still present. It acts normal when copying small amount of data. Also, I heard that some intel chipsets have an issue with usb, something about the connectors not transferring power when the usb device enters some kind of "low power mode" causing the device to stop responding and you need to plug it out and in again. But the thing is, my Intel® Chief River Chipset HM76 is not on the list of affected hardware(not ENTIRELY sure though). If anyone has any idea of what the problem to this might be, I'd be greatful. Edit: The hdd works perfectly fine even for large amounts of data if plugged in the usb 2.0 port!

• Upstart multiple instances of service not working

  - by Dax

  I started playing with MongoDB on Lucid. Now I would like to run a DB and Config server on the same box. They both use the same binary to launch, but with different config files and running on different ports. All directories for log and lib is split so one goes to mongodb and the other to mongoconf. Each process can be started without any problems on their own. start mongodb stop mongodb start mongoconf stop mongoconf But if I try to start both, the second one would just start and exit. Using 'initctl log-priority debug' I got the following in the logs. Jan 6 12:44:12 mongo4 init: event_finished: Finished started event Jan 6 12:44:12 mongo4 init: job_process_handler: Ignored event 1 (1) for process 5690 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) main process (5690) terminated with status 1 Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) goal changed from start to stop Jan 6 12:44:12 mongo4 init: mongoconf (mongoconf) state changed from running to stopping man 5 init shows that you can use instance names to differentiate the two. I tried using 'instance mongoconf' in the on upstart script and 'instance mongodb' in the other one, and it still fails. I can manually start the other process, so there is definitely no conflicts on port numbers or directories. Any ideas on what to try or how to get output on why it is 'terminated with status 1'? Thanx

• Solr startup script problem

  - by Camran

  I have installed solr and it works finally... I have now problems setting it up to start automatically with a start command. I have followed a tutorial and created a file called solr in the /etc/init.d/solr dir... Here is that file: #!/bin/sh -e # SOLR auto-start # # description: auto-starts solr engine # processname: solr-production # pidfile: /var/run/solr-production.pid NAME="solr" PIDFILE="/var/run/solr-production.pid" LOG_FILE="/var/log/solr-production.log" SOLR_DIR="/etc/jetty" JAVA_OPTIONS="-Xmx1024m -DSTOP.PORT=8079 -DSTOP.KEY=stopkey -jar start.jar" JAVA="/usr/bin/java" start() { echo -n "Starting $NAME... " if [ -f $PIDFILE ]; then echo "is already running!" else cd $SOLR_DIR $JAVA $JAVA_OPTIONS 2> $LOG_FILE & sleep 2 echo `ps -ef | grep -v grep | grep java | awk '{print $2}'` > $PIDFILE echo "(Done)" fi return 0 } stop() { echo -n "Stopping $NAME... " if [ -f $PIDFILE ]; then cd $SOLR_DIR $JAVA $JAVA_OPTIONS --stop sleep 2 rm $PIDFILE echo "(Done)" else echo "can not stop, it is not running!" fi return 0 } case "$1" in start) start ;; stop) stop ;; restart) stop sleep 5 start ;; *) echo "Usage: $0 (start | stop | restart)" exit 1 ;; esac Whenever I do solr -start I get this error: "Error occurred during initialization of VM Could not reserve enough space for object heap" I think this is because of the file above... Also here is where I have solr installed: var/www/solr and here is the start.jar file located: var/www/start.jar Help me out if you know whats causing this. Thanks BTW: OS is ubuntu 9.10

• 802.11g -> wired ethernet bridging not working

  - by Malachi

  Usually people want to go the other direction, but I want to take our relatively fast and stable house 802.11g signal and bridge it to ethernet. I have tried using an Airport Express (the b/g flavor) and my i7 MacBook pro, both to no avail. Word is that the b/g flavor of This flavor of Airport Express maxes at firmware 6.3 which doesn't support this kind of bridging properly. However, I expected my MacBook pro to do the job with its "Internet Sharing" feature. Alas, although my wired PC does sort of see it, it doesn't work out. Strangely, using DHCP the PC receives the same IP address as my MBP uses on the network. Less strangely, but still surprisingly, the wired ethernet port on my mac registers as the IP address of the gateway when queried with IFCONFIG. It sort of makes sense that the mac would "pretend" to be the gateway, but the whole thing just isn't working and seems configured wrong - but all the docs I see say basically "OS X Internet Sharing: click it and go". What do I do? Do i really have to buy more hardware, even though I have plenty of would-be candidates for bridging? Incidentally, the host router originating the 802.11g signal is a belkin 802.11g router, and is documented to support WDS.

• How can I update generic non-pnp monitor?

  - by njk

  Background I've been running a KVM switch with my monitor at 1920 x 1080 over VGA for over a year. Did a Windows Update on 12/11/12 which did the following: Update for Windows 7 for x64-based Systems (KB2779562) Security Update for Windows 7 for x64-based Systems (KB2779030) Cumulative Security Update for Internet Explorer 8 for Windows 7 for x64-based Systems (KB2761465) Windows Malicious Software Removal Tool x64 - December 2012 (KB890830) Security Update for Windows 7 for x64-based Systems (KB2753842) Security Update for Windows 7 for x64-based Systems (KB2758857) Security Update for Windows 7 for x64-based Systems (KB2770660) After a restart, my extended monitor was dark. I attempted to reset the extended display configuration, and noticed my monitor was being detected as a Generic Non-PnP Monitor: I uninstalled, downloaded new, and re-installed display drivers. Nothing. I attempted to unplug my monitor from the power for 15 minutes. Nothing. I followed some of the suggestions on this thread; specifically DanM's which suggested to create a new *.inf file and replace that in Device Manager. Device Manager said the "best driver software for your device is already installed". The only thing that works is when the monitor is directly attached to the laptop. This obviously is not what I want. My thought is to somehow remove the Generic Non-PnP Monitor from registry. How would I accomplish this and would this help? Any other suggestions?

• Why does Windows Firewall want to block Google Chrome today?

  - by hippietrail

  I've been using the same public Wi-Fi (staying in a guesthouse) for over a week now. But this morning for the first time I got this puzzling warning from Windows Firewall: Why does Windows Firewall want to block one of the world's most popular web browsers today after being fine with it for years, and being fine with it on this connection for a week? Could it hinge on the words, some features? If so could it be something like a rare or new feature of Chrome that uses a different HTTP port? And if so why doesn't the security alert tell me any more about it? Or could it be a known bug in Windows Firewall? Or perhaps a known virus etc attaching itself to Google Chrome? Or is there a chance it's related to "Other browser makers follow Google's lead, revoke rogue certificates"? I haven't restarted Chrome for days and have downloaded but not installed a Windows update from a few days ago. So I'm not sure what may have managed to change on my machine since yesterday.
