• maximum number of connections Squid

  - by Isaac

  I have a Squid proxy server that controls all internet traffic for my network. I need a way to stop users from downloading big files (say 50MB) in my network. I banned some famous ports (e.g. torrent) but some downloads are possible by HTTP port. Obviously I cannot ban port 80! A simple solution is limiting maxmimum number of the simultaneous connections for each IP (e.g. 3 connections). It's possible in Squid with this config: acl ACCOUNTSDEPT 192.168.5.0/24 acl limitusercon maxconn 3 http_access deny ACCOUNTSDEPT limitusercon But this solution has really bad impact in web browsing, because any smart browser get different parts of a website by several connections simultaneously to speedup web browsing. But if we have a maximum number of connections, the browsers will fail to get some parts and the website will be shown partially and some parts/images/frames will not be shown. So, can we limit maximum number of persist connections? I think this policy will works: Specify Maximum number of connections that is alive for 10 seconds But Number of simultaneous connections for every IP is unlimited But how can we implement this policy when Squid? With which config? UPDATE: artifex and Tom Newton offered using a bandwidth-limiting approach to fight against downloaders. But bandwidth-limiting in Squid has a shortcoming: It's static and cannot dynamically change. So a person has a limited bandwidth not matter how many people are using internet (maybe nobody!) Also, this solution cannot help to stop people from downloading. They still can download but in a lower speed. But if we find a way to terminate persist connections (or any connection that is alive more than a specific time), downloading big files will be almost impossible (always there is some way!)

• Dovecot authentification not working

  - by user1488723

  I run a Ubuntu 10.04 VPS with Postfix and Dovecot installed. For a while I had problems with the mailserver itself (Postfix) but now it runs ok. I can telnet into it from localhost (telnet localhost 25 while logged in) and Im blocked if I try to do it from the outside (telnet mail.example.org 25). This is as it should be according to my main.cf However when I try to log in using Dovecot (openssl s_client -connect mail.example.com:993) I'm allowed in but denied when trying to identify myself as a user: Excerpt from Dovecot log in: Key-Arg : None Start Time: 1341074622 Timeout : 300 (sec) Verify return code: 18 (self signed certificate) OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN AUTH=LOGIN] Dovecot ready. When I continue and try to log in to a specific user with the command: A001 login user password I get: A001 NO [AUTHENTICATIONFAILED] Authentication failed. I've reset the password to ensure it is correct and I know the user (user) exists on the system. When I do /etc/init.d/dovecot reload I get: /etc/init.d/dovecot: 29: maildir:~/Maildir: not found * Reloading IMAP/POP3 mail server dovecot [ OK ] Could it be that the mailboxes isn't found?

• NGINX Configuration Error using Codex Example: Is This a Typo in Codex?

  - by jw60660

  I installed NGINX using this tutorial: C3M Digital NGINX Tuturial but after reading this article on security issues with "cut and paste" configuration tutorials: Neal Poole's article regarding security and NGINX configuration I decided to follow Poole's suggestion to use the configuration suggested in the WordPress codex: Codex on NGINX Configuration I used the Codex configuration for a multisite installation using W3 Total Cache. When attempting to start NGINX I get an error saying that the /etc/nginx/nginx.conf test failed. The error message was: "Restarting nginx: nginx: [emerg] unknown directive "//" in /etc/nginx/sites-enabled/teambrazil.com:18" When I looked at my site specific configuration at that path I noticed the rewrite rule in the server block was: rewrite ^ $scheme://teambrazil.conf$request_uri redirect; That line in the Codex example was: rewrite ^ $scheme://mysite.conf$request_uri redirect; That looked like a mistake to me, and I changed my line to: rewrite ^ $scheme://teambrazil.com$request_uri redirect; I then attempted to restart NGINX but got the same error message. My question is: is that a mistake, and is there anything more I have to do aside from restarting NGINX after making this change. As suggested by both tutorials I set up the directories: /etc/nginx/sites-enabled and /etc/nginx/sites-available and created the appropriate symbolic links using: touch /etc/nginx/sites-available/teambrazil.com ln -s /etc/nginx/sites-available/teambrazil.com /etc/nginx/sites-enabled/teambrazil.com Is there something else I need to consider after making this correction? Or was it not an error in the first place? I'm pretty stuck here. BTW, I am using Debian squeeze as an OS on Amerinoc's VPS. I'm just getting familiar with VPS administration and am pretty much a noob. Thanks very much, would appreciate any input.

• Windows 2008 IIS 7.0 HTTP to HTTPS Redirect -- Versus IIS 6.0 Mechanism

  - by Dan7el

  This topic, creating a mechanism for redirection from HTTP to HTTPS on a Windows 2008 server running IIS 7.0 is a much written-about topic on the Internet. How this is done is really not so much my issue. My issue is more of explaining why this can't be done with the standard HTTP Redirect module that ships with Windows 2008 IIS 7.0. Instead, there are other methods needed that are more arduous. First, the IIS 6.0 method requires no externally available modules nor does it require any additional modifications to the web.config or any type of other development effort. It's outlined here: http://blogs.microsoft.co.il/blogs/dorr/archive/2009/01/13/how-to-force-redirection-from-http-to-https-on-iis-6-0.aspx And, you can see the basic steps are to run the snap-in, get the properties on the site, and do some modifications. Presto, you have the HTTP -- HTTP redirect setup. Now, on the IIS 7.0 platform, it doesn't seem this simple. An initial search found the following site: http://www.sslshopper.com/iis7-redirect-http-to-https.html Which has two separate approcates: 1. Involves installing a separately available Microsoft module -- URL Rewrite Module, and then adding XML to the web.config. 2. Custom Error Page. ...there might be other methods, but these are the basic ones and the first is listed as the primary method. But wait...There exists on the IIS 7.0 an HTTP Redirect Module. So...why can't I use the HTTP Redirect Module to do this very thing? This is really my big question. I need to know this because my management is going to insist I use the HTTP Redirect Module and set up the HTTP to HTTPS redirect in a similar fashion to how we do in IIS 6.0. Can someone please explain to me, in clean, simple, easy to understand, terms that both I and my management can understand as to why I need to go get the URL Rewrite Module and install that on the server and make the web.config changes suggested by the article instead of simply using the HTTP Redirect module that's already installed on the site? Thanks a bunch.

• VMWare Setup with 2 Servers and a DAS (DELL MD3220)

  - by Kumala

  I am planning to use a VMWare based setup consisting of two VMWare servers (2 CPU, 256GB Memory) and a DAS (DELL MD3220 with 24x900GB disks). The virtual machines will be half running MS SQL databases (Application, Sharepoint, BI) and the other half of the VM will be file services, IIS. To enhance the capacity of the storage, we'll be adding a MD1220 enclosure with another 24x900GB to the MD3220. Both DAS will have 2 controllers. Our current measured IOPS is 1000 IOPS average, 7000 IOPS peak (those happen maybe twice per hour). We are in the planning phase now and are looking at the proper setup of the disks. The intention is to setup up both DAS one of the DAS with RAID 10 only and the other DAS with RAID 5. That will allow us to put the applications on the DAS that supports the application performance needs best. Question is how best to partition the two DASs to get best possible IOPS/MBps, each DAS will have to have 2 hot spares? For the RAID 5 Setup: Generally speaking, would it be better to have one single disk group across all 22 disks (24 - 2 hot spares) with both controllers assigned to the one disk group or is it better to have 2 disk groups each 11 disks, assigned to one of the two controllers? Same question for the RAID 10 setup: The plan is: 2 disks for logs (Raid 1), 2 Hotspare and 20 disks for RAID 10. Option 1: 5 * 4 disks (RAID 10), with two groups assigned to 1 controller and 3 groups to the other controller Option 2: One large RAID 10 across all the disks and have both controllers assigned to the same group? I would assume that there is no right or wrong, but it all depends very much on the specific application behaviour, so I am looking for some general ideas what the pros and cons are of the different options. IF there are other meaningful options, feel free to propose them.

• Debugging Windows PC freeze

  - by Violet Giraffe

  I have a problem with my computer, would appreciate any hints/ideas. It usually begins not immediately after booting Windows, but at some unpredictable point in time, which doesn't seem to correlate with any specific actions of mine. First sign of a problem is process System starting to consume 25% CPU time steadily. I have a quad-core CPU, so it might be one thread working non-stop. At this point micro-freezes start to occur - screen stops refreshing, but if I have, say, music player running - it continues playing. If I try to do something between the freezes, like open Start menu, it will freeze completely and forever. If I press reset button the PC will shut down and then start cold, as opposed to usual reset behavior (which doesn't include PC shutting down). I have noticed that full restart upon reset is usual for hardware problems, but I think this problem isn't related to at least motherboard-CPU-RAM-videoadapter. It certainly isn't caused by overheating. One very important not is that it seems to be related to Windows hosted WLAN network: I have USB Wi-Fi dongle and have configured a hosted network to share cable Internet connection with Wi-Fi devices. I am not 100% certain there's a strong connection, but in 9 or 10 cases when I enabled the network (by executing netsh wlan start hostednetwork), it did freeze eventually (sometimes within minutes of starting the network, sometimes within hours), and on at least 10 days when I didn't start the network it never froze, no matter how I used the computer). There are no critical/error entries in the events log that I can suspect as being related, only regular stuff like "driver not loaded". I have found no critical/error events that are being logged around the time of freeze occurring and are not logged during normal boot without starting the WLAN.

• Disconnect from PHP after output generated

  - by Oli

  I have a LEMP stack. Nginx sitting in front of PHP-FPM. Because some of the sites are heavy and there's OPCode caching, PHP is set up so that there are only 5 child processes running. The aim being that each child can deal with any request in less than half-a-second and then move onto the next request. One problem I've found is that if it's a big chunk of HTML that's getting sent out, and the user has a slow connection, that PHP thread stays occupied until they've finished downloading. Because of my current setup, I have a pretty unforgiving timeout inside PHP where the script is killed after 20 seconds. This is to make sure everybody gets a turn but on a slow connection, this can mean the user gets cut off with a 504 Gateway timeout. I was wondering if there was some sort of buffer solution that I could implement within or just behind Nginx that sent the request through and then... well... buffered the content into its own cache and feed that onto the client as and when they could download it. The aim being that the underlying PHP thread can be freed up. What I'm asking for doesn't have to be PHP-specific. Anything that deals with FastCGI, or even any Nginx-upstream might have a similar issue to this.

• SSL timeout on some sites, across all browsers, on Mac OS X Snow Leopard

  - by dansays

  For the past several weeks, I've been receiving "Error 7 (net::ERR_TIMED_OUT): The operation timed out" when I attempt to connect to either Twitter or Paypal via SSL. I get this specific error in Google Chrome, but the same problem occurs in both Safari and Firefox. Other sites work fine, and other computers on my network can access these two sites. I have no firewall settings that would prevent me from accessing these sites over port 443. I notice that both Twitter and Paypal both have "Verisign Class 3 Extended Validation SSL CA" certificates. It is unclear whether this is related to the problem. In an effort to troubleshoot, I attempted to open the test sites referenced on Verisign's root certificate support page, which worked fine. Just to be sure, I downloaded and installed the root package file and installed all included Verisign certificates. No joy. I feel like I've hit a dead end. Any ideas? Update the first: I also cannot connect to FedEx.com, who also has a Verisign Class 3 Extended Validation cert. Update the second: Aaaaaaand it fixed itself. I did nothing. Or, I did something that worked, but in a delayed fashion. Frustrating, but a win is a win. I'll take it.

• Network Load Balancing and AnyCast Routing

  - by user126917

  Hi All can anyone advise on problems with the following? I am planning on installing the following setup on my estate: I have 2 sites that both have a large amount of users. Goals are to keep things simple for the users and to have automatic failover above the database level. Our Database will exist at the primary site and be async mirrored to the secondary site with manual failover procedures.The database generate sequential ID's so distributing it is not an option. I plan to site IIS boxes at both sites with all of the business logic on them and heavy operations. The connections to SQL will be lightweight and DB reads will be cached on IIS. On this layer I plan to use Windows network load balancing and have the same IP or IPs across all IIS boxes at both sites. This way there will be automatic failover and no single point of failure. Also users can have one web address regardless of which site they are in automatically be network load balanced to their local IIS. This is great but obviously our two sites are on different subnets and as this will be one IP address with most of our traffic we can't go broadcasting everything across the link between the sites. To solve this problem we plan to use AnyCast routing over our network layer to route the traffic to the most local box that is listening which will be defined by the network load balancing. Has anyone used this setup before? Can anyone think of any issues with this? Also some specifics I can't find anywhere at the moment. If my Windows box is assigned an IP and listening on that IP but network load balancing is not accepting specific traffic then will AnyCast route away from that? Also can I AnyCast on a socket level?

• Slow Local Network, Windows 7, Snow Leopard, WiFi/Wired

  - by WerkkreW

  Hello - I am experiencing really poor local network performance in my home. I was recently using a Linksys WRT54G Router with DD-WRT on it, and a couple comparable Linksys-G PCI cards for connectivity but decided to upgrade hoping it would help with my performance issues. The computers in my house are connected as follows: Comcast Business Class Commercial 25mbps/10mbps (Verified with SpeakEasy and Speedtest.net) D-Link DGL-4500 Wireless N Router Windows 7x64 - D-Link DWA-552 Wireless-N Windows 7x64 - D-Link DWA-552 Wireless-N Mac Mini 10.6.2 - AirPort Extreme N Playstation 3, Hard Wired Xbox 360, Hard Wired Essentially the problem is very specific. Web browsing and uploading/downloading files from the internet is fine, more than fine. But if I want to say, Stream a video from one of my Windows 7 computers to my PS3, or copy a large video file between either of the PC's or the Mac, I get a consistent 500-900Kbps throughput at the high end. If I open my network browser, or try to browse my homegroup the response time is horrible. Both of my Windows computers are showing Strong wireless signals with a connection speed of 300Mbps. I know I can never expect to achieve anything near those speeds, but 500Kbps? Here is what I have tried so far: Enabled Single mode N-only and N/G Only on router WPA2 with AES Encrpytion Disabled "Remote Differential Compression" in Windows 7 Disabled TCP "Auto-Tuning" Used other software for file copies such as "Teracopy" I am at the end of my rope. Unfortunately I live in a 75 year old home with plaster walls, so hard-wiring my entire house isn't really an option I can handle right now. Any ideas to help me get decent speed when transferring files across my network would be greatly appreciated.

• picking a linux compatable motherboard

  - by Chris

  Last time I bought a new computer (I build them myself) I got a motherboard that had really poor linux support for a long time. Specifically the audio. I had to wait months before the kernel supported the on board audio chipset. That is exactly the situation I'm trying to avoid this time around. I have some specific questions about "server motherboards" actually. I looked at a few models of server motherboards by intel, and some random models on newegg. I wasn't able to see much of a difference from regular desktop motherboard other than most had two sockets, and support for much more ram. These boards seem more popular with Linux users. Why? AMD and Intel both have server CPUs as well. Some question, what's the difference? To make this question more concrete, I was looking at this this motherboard. The main questions about it that I can't answer are: Can I get a motherboard without on board raid and audio? I wanted to get a hardware raid controller and a PCI audio card. I thought a server motherboard would be cheaper and not have these "extras", since who wants an audio card on a server? Where can I found out about Linux support for the components on this board? "Intel ICH10R", "Realtek ALC889", "Marvell 88E8056" I'm buying this computer to work as a Linux desktop for a lot of compiling, coding and audio/video work, but I don't want to rule out the possibility of installing windows and playing some games at one point. (even if the last game I got has been sitting in its box unopened for almost a year). Is it a good idea to buy a "server motherboard" and play games on it, or are desktop boards better value for this? The ultimate solution for me would be a motherboard that had GPL divers for onboard LAN, a single CPU socket, lots of PCI express and PCI. USB 3.0, and no fancy hard disk controllers since I'll be getting a separate one.

• how to download vim script in command line

  - by HaiYuan Zhang

  whenever I want to install a new vim script to the linux server I'm working in , my typical workflow is as the following: surf the plugin's homepage in vim online using fireXXXX download a right version of the plugin to my laptop by click some highlighted link upload the downloaded plugin from my laptop to linux server using winscp which is really inconvenient. I don't know what is the magic behind this : I mean for the same hyperlinki click it in web browser I can let you download it but use wget plus the hyperlink in linux commandline will end up with nothing but error indication. hyperlink in web browser . otherwise I can get the link in web browser and then use wget or some similar tool to actually do the downloding. I try new cool vim scripts quite often , so you can imagin my dismay when have to repeat the tedious action all the time. So if anyone of you knows some tips which can let me downloading the vim scripts in a more "professional" way, I'll appreciate it a lot. post edit : My problem is not find a tool like wget or curl . The problem I met is quite specific to use these tools to download vim script. let's take http://www.vim.org/scripts/script.php?script_id=30 as an example, it's the normal place where one can get the script, at least for me. but I can't find an working url from this page that can feed to wget .

• How to use Cisco AnyConnect VPN Client?

  - by ktm5124

  I wrote a related question earlier, which is still unresolved. This question is much more specific. So I installed Cisco AnyConnect VPN Client on Snow Leopard. I connect to my work VPN. Once connected, I can't ping my work machine. I don't see any computers on the network. If the client were not running, I wouldn't believe myself to be connected to the VPN. Is there something that I am doing wrong? Do I have to route my network traffic through the tunnel manually? (ifconfig route comes to mind) Is the POST request that I am about to submit going to go through the tunnel created by my VPN? I guess the main question is: why do I feel so in the dark? Cisco says I am connected to my VPN, but for all I know it is invisible. N.B. I do have the up-to-date Cisco VPN Client: version 2.3.2016. I installed it about a week ago.

• How should I convert a physical drive to a VHD for use with VirtualPC?

  - by RBerteig

  I have the hard disks from a PC that was happily running Windows Me until is it suffered an unknown hardware failure. The drives are intact, and can be mounted and read on other PCs. We have data backups, but there is licensed software installed that may not be possible to migrate to newer versions running on a more modern platform making the idea of just booting a virtual image attractive. Is it possible to make VHDs from the drives such that I can boot them in VirtualPC? If not VirtualPC, would it be possible in any other virtualization tool? Edit: Some more details.... The system was running Windows Me, but upgraded from Windows 95 (or possibly 98). It can't have been more than a Pentium II, but I will have to look at the motherboard to confirm that. There were no "exotic" devices installed, and nothing beyond the usual legacy stuff that would need to survive into a virtual machine. The licensed software did not have a dongle, so I won't need to worry about virtualizing a physical dongle of some kind. Licenses were probably died to the disk serial number. There were two HDs, both IDE. The boot disk is about 6GB, and the spare data disk is 12GB, but nearly empty. I have a small bias in favor of VirtualPC just because its free and I've used it successfully in the past. But this is a good excuse to revisit the state of the art. I do know from direct experience that it is possible to install and boot DOS 5.0 and Win95 in VirtualPC, but the VM extensions weren't available so the experience isn't as seamless as I would have liked. A very old DirectX game that failed miserably under XP SP2 runs really nicely on that VM, and actually plays better in a lot of ways than it did on period hardware, so that gives me hope that this is possible. Edit 2: Well, I'm closer than I was when I asked... so thanks to all for helpful suggestions and hints to what I should be trying. I used WinImage to copy the disks, and VirtualPC 2007 to attempt to boot. So far, I have it booting in safe mode, but hanging with a black screen otherwise. I strongly suspect that the copy of Artisoft Lantastic 8.0 (anyone else remember them?) that is still installed for networking with even older PCs that mostly don't exist any more is the culprit there. In my infinite free time, I will try to resolve the differences between a Safe Mode boot and a normal boot, and feel that it is likely to yield to pressure. I'd accept more than one answer if I could... this isn't as black and white a question as the one accepted answer convention assumes.

• Repairing hard disk when Windows installation disk won't boot

  - by Echows

  I'm trying to recover some data from a faulty hard disk with Windows installed on it (on which Windows won't even boot). I have tried so far: Booting to Ubuntu live USB stick and running ntfsfix (didn't work) Trying to mount the broken partition when running Ubuntu from usb stick (doesn't mount) Running photorec image recovery tool from live Ubuntu (it found some stuff but not the images I was looking for) Now as a last resort I got myself a Windows installation on a USB stick so that I can try fdisk, but the installer doesn't work. The loading screen shows up and then the installer crashes. The installer works fine on other computers. I suspect that the installer is trying to read the hard drive to see if there's something there but when it can't read one partition, it crashes. On Ubuntu, I can mount other partitions except the one I'm interested in so at least the hard drive is not completely dead. So the question is, what options do I have left? To be more specific, my goal is to recover some images from the faulty ntfs-partition on the hard drive. Other than that, I don't care about the contents of the hard disk.

• smartctl short test doesn't seem to complete

  - by Cédric COPY

  I am working on project which involve automated HDD testing through smartctl. The station is working fine on most product, but I have two specific products that fail the smartctl test. Those two product are both WD product (WD2500BUDT series) Smartctl behaviour is quite strange, in fact the test is launched without any problem, i wait about 2min (test length), and when i check the smartctl, i have got no result at all. It's like I hadn't launched any test (no fail, no success in smartctl result). No error return on command, nothing in syslog, .. As i said before, the test is working for other product, thousands products worked well with this test. The main smartctl command used are : smarctl -t shortest /dev/sdX #Launch test smartctl -l selftest /dev/sdX #Look at test result I have tried to use: smartctl -s on /dev/sdX or smartctl -o on /dev/sdX But doesn't change anything. The system is using Debian 6.0, smartctl v5.40 (rev 3124) x86_64, HDD are plug through SATA to PCI controller. I have 4 HDD connected at a time. Well if anyone has some hints to give with this problem, because I have no idea how can i fix this. Thanks in advance. PS: Not sure if it was a serverfault topic, sorry if i was wrong!

• Software/hardware to build video streaming server?

  - by Sasha Yanovets

  I am looking for a video streaming server solution, something like online TV server, with ability to make live broadcasts in the internet. What software could you recommend for that? What kind of hardware it should run on, should be there anything special? I am looking for a solution that could be scaled up to at least 1000 simultaneous users online with good resolution of video. I think it is good to have general answer on what direction to choose. But here more details on my specific case: I just looking for a solution almost from scratch. We have some video content that we've produced, but it is not delivered over internet yet. We do not tied to any particular vendor for now. We want to make 24 hours of steaming three 8 hour blocks with change of content every day. We want the ability to make regular live broadcasts. I guess we will need to have several options of streaming quality (low ~56 kb/s mid ~273 kb/s). Some terms just foreign to me (like play-truncation rate), if you could point out what parameters we should avare of, it would be great. Uplink to the internet is to be determined. We plan to start from something and scale up on the way. If you are already have some kind of media streaming server, just describe its configuration here (hardware, OS, software), peak number of concurrent users it serves. I think it could help people approaching this task.

• Can Windows logoff events be tracked?

  - by Massimo

  I'm working on an application to track network user logon/logoff events in an Active Directory domain; the application will work by auditing security logs on domain controllers. Auditing logon events can get somewhat tricky, but it can succesfully be done. My problem: how can I track logoff events? Based on some research I've done, it looks like these events are only logged locally on workstations, but not on DCs; also, the "lastLogoff" attribute exists on AD user objects, but it's not actually used by anyone. This is a very specific question: is something logged on DCs when a user logs off from a domain workstation? To clarify: I'm not intereseted in other auditing mehods, I can't deploy logon/logoff scripts and I can't install anything anywhere; I also know opened and closed network sessions are logged, but this is not what I'm looking for. I need to audit interactive logons and logoffs to domain workstations, and I can do this by only reading domain controllers security logs; reading each workstation's local event logs is out of question. If this can't be done, it's ok; but I need a clear answer on that. Can this be done? If yes, how?

• 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?

• Disable CTRL+mouse wheel zooming in Chrome?

  - by Peter Nore

  I'm a normal-sighted person and I would like to view pages at 100% all the time. I use keyboard shortcuts that involve CTRL a lot, so about twenty times a day I accidentally hit CTRL at the same time that I'm scrolling, which results in the page being reflowed and repainted. This in is annoying because it can take up to 30 seconds to fix the issue, depending on how complex the site layout is. On sites with dynamic layout such as Google Docs the problem is more serious; accidentally hitting CTRL+mouse wheel corrupts the display and forces me to refresh the page entirely, sometimes causing me to loose information in the process. I would like to either decouple CTRL+mouse wheel from zoom, or disable zoom functionality altogether. This is possible on Firefox by using about:config; is there a similar way to edit detailed settings in Chrome? Would I have access to the detailed settings if I used Chromium instead of Chrome? I'll probably jump ship back to Firefox if I can't solve this problem. There is a superuser question that asks basically the same thing I'm asking, but for Firefox and Internet Explorer exclusively. Other people on the Chrome forum have had related issues, but none have the same problem. "I would really like it if I could deactivate the auto zoom in/out." had "something with laptops and Windows 7", not the feature built into Chrome. Other people have had PDF specific issues, which doesn't concern me. I've also tried searching for extensions that allow you to disable the scroll; I had hoped that "Zoom Lock" would have the ability to lock the zoom at 100% and prevent CTRL+scroll wheel from distorting the display, but it doesn't work for my use case. Google Chrome version 9.0.597.84 (Official Build 72991) Operating System: Ubuntu 10.10

• Is there a realiable way to troubleshoot wake up from sleep in Windows?

  - by Borek

  Is there a reliable way to troubleshoot laptop wakes? I've seen "heuristics" posted here and there but isn't there really a simple and deterministic way to tell what's causing a problem? Specifically, my laptop wakes up about every hour for about 2 minutes. Exported event log entries are here: http://www.mediafire.com/?abcqb00v5wyo6pj. I've tried: powercfg -devicequery wake_armed Empty result set. Scheduled tasks - the main ones are not scheduled to run every hour. When go through a long list of all possible tasks, there are some that are set to be triggered every hour (e.g., MS "RacTask" whatever it is). But when I go to power options, Advanced settings, Sleep, Allow wake timers it is set to "Disable". Also, the specific task is not set to wake the computer if necessary. Power options for my Ethernet card don't enable it to wake the computer - the cable is disconnected anyway. There are no other HW devices attached - no USB disks, no keyboards / mice etc. I am really clueless and quite unhappy that it's so hard to troubleshoot this situation.

• Solaris 10: How to image a machine?

  - by nonot1

  I've got a Solaris 10 workstation that I'd like to create a full image backup from. The machine has 2 drives, one UFS for system root, and 1 ZFS for data storage. I intend to add a third HD to keep the backup images of both primary drives (including any zfs snapshots). The purpose is not disaster recovery, but rather to allow me to easily blow away a series of application installation/configuration changes I intend to try. What's the best way to do this? I'm not too familiar with Solaris, but have some basic Linux knowledge. I looked at CloneZilla, but it does not support Solaris. I'm OK with just a dd | gzip > image style solution, but I'd need some way to first zero-out the non-used blocks on the primary drives to aid gzip. They are are much larger than my 3rd drive, but hardly have any real data. Update to clarify: I specifically want to avoid using any file-system snapshot functionality, because part of the app configuration changes involve/depend slightly on existing and new snapshots. Ideally the full collection of snapshots should be part of the backup. Virtualization not an option, because the goal is to do performance evaluation on a very specific HW configuration. For the same reason, the spurious "back up" snapshots could skew performance data. Thank you

• Suddenly can't send E-Mails with Apple Mail to Gmail SMTP

  - by slhck

  Hi all, I have a weird problem that started just today. I am using Apple Mail on a Leopard machine, connecting to Gmail. Fetching e-mail works just fine. My SMTP settings are also correct. Still, I can't send mail, it will display a pop up saying that "transferring the content to the mail server" failed (translation from German, could be different in English OS X versions). I have verified the following: My SMTP settings are definitely correct. I have not changed them and the issue appeared today. Also, I went through the Apple online configuration for Gmail accounts and did not have to adjust any setting. I can run network diagnosis and it will connect to both POP and SMTP servers without a problem (all green lights) The Telnet details will show me the HELO message from the Gmail servers, so there's no authentication failure. Console.app will not show any messages related to "mail" when I try to send the mail, so there's no specific error message The mail I'm trying to send does not have an attachment, it is plaintext only I can login to gmail.com and send mails without a problem The recipient address exists and contains no syntax errors I can also not send mails to myself When using another IP and ISP (through VPN), it still doesn't work As for my settings: I connect to smtp.gmail.com and for advanced settings I choose password-based authentication with user: [email protected] and my password. I let Apple Mail try the default ports (for SSL and TLS, respectively). Again: I have not changed a thing between yesterday and today. What is causing that strange behavior? Any help would be much appreciated.
