  • Slow internet using Arch Linux

    - by GZaidman
    after a week or so of using Arch Linux I cant access the internet - it takes around 5 mins to load google (most of the other websites just give me a timeout), pacman's downloading speed range between 5-2Kbs, and pinging google takes around 9Kms. I'm connected using wireless network (wifi card is Intel Ultimate 6300 and router is Edimax 6524n). Every other Windows machine that's connected to the network (and even the T410 running Windows) is fine, so the problem lies in Linux. So far, i checked the resolv.conf file (my router ip address is listed), and the hosts file (pretty much default), and I disabled the ipv6 module. None of that helped. PS: i'm using NetworkManager (but the problem still occurs when connecting using wicd) running on Gnome3. Thanks in advance for any help you can provide! EDIT: something really strange happens whenever I ping google: i get an unknown host 'google.com', but the bit rate from the card jumps at the exact second I ping google (so far, the bit rate jumped to 54Mb/s from 1Mb/s over the course of 4 pings).

  • DNS servers via RA in IPv6

    - by glglgl
    Some time ago, RFC 6106 was created, which states how a router tells the clients about the DNS server to be used. It is a new standard, it has to be implemented, which needs time etc. I'm courious about the need for it: wouldn't have it been better to define a "globally valid" anycast address for DNS? Queries would be sent to this address and would be promoted along the default route until there is a host which claims to be responsible for it. In an enterprise network, that would be a central DNS server (or even more, on really big companies); in a SOHO network, it would either be the router or the DNS server of the ISP, in a root server hosting data center, it would be the DNS of the hoster, etc. What do I see wrong here? Do I have a wrong view of the anycast concept?

  • I'd like to rebuild my web server without web management software; what knowledge, skills, and tools will I require? [closed]

    - by Joe Zeng
    I've been using Webmin for my web server that runs my personal website and a host of other websites for a while now, and I feel like I should be able to manage my web server more directly, because I haven't even touched the Webmin for the past year or so and I feel like maybe it has too much functionality that I have to click through the next time I want to access it or create a new subdomain or database on my site. I want to try something lighter and more wholly manageable, now that I'm more comfortable with using ssh and command-line tools. I've decided that I'm going to try using Django as a framework, but obviously that's only part of the picture. What sort of knowledge will I require?

  • Microsoft DNS creating subdomain when adding address record

    - by dwdet
    Hello, When attempting to add a normal A record (which has so far always worked), the Microsoft dnsmgmt app in MMC is returning a successful creation message "The host record oneworld.mydomain.com was successfully created". However, after refreshing the zone, it displays a folder icon next to "oneworld" indicating a sub domain, i.e. it is not the A record dnsmgmt said it created successfully. This is really strange behavior that has never happened previously. We have tried this on two separate PCs and remote consoled into the primary DNS server and tried adding the same A record with the same results. Any help is appreciated.

  • Live CD with good anti-virus software to scan/repair Windows?

    - by overtherainbow
    Hello, I browsed through the archives, and it seems like there's no live CD from which to run a good, up-to-date anti-virus application, at least to check whether a Windows host has been compromised The Ultimate Boot CD has only three AV applications, and their virus definition is from... 2007 In a report, ClamAV scored very low. It's nice that it's open-source, but if it's not as good as commercial alternatives... Those of you into this kind of thing, do you confirm that there's just no good live CD to inspect Windows hosts, and possibly repair them? If there is, what do you recommend? Thank you.

  • VmWare / Citrix Xen type environment vs Ubuntu Cloud / Amazon EC2 type environment.

    - by Nick Gorbikoff
    Hello. A bit of background. We run a small in house data center: about 20 virtualized servers (Debian Lenny, Windows 2003, Windows xp and Windows 7 machines), in a Citrix Xen pool running on 3 host servers and a SAN, plus a few standalone machines running legacy or specialized software that can't be vritualized. There is a big push everywhere now to move to cloud so we considering Ubuntu Cloud. I was wondering what are the pros / cons of running virtualized pool vs cloud to run all those machines? Thank you

  • How to configure a gateway virtual machine

    - by user225706
    I have a VM-host configured with eth0 (10.145.73.207) and eth1(192.168.101.231), and three VMs connecting the Internet through NAT, with the default gateway of 192.168.122.1. Now I want to configure VM2 as a gateway. I added eth0 (192.168.122.63) and eth1 (172.16.1.109) for VM2. It can connect to the Internet with each of them. I changed the default gateway of VM1 from 192.168.122.1 to 192.168.122.63. However, when I traceroute google.com on VM1, it shows that the packet only reaches 192.168.122.63, no further. Any help is appreciated. Thanks.

  • pound: multiple domains

    - by niklassaers
    Hi guys, I've been using pound to run mydomain.dk. Now I've bought some other domains and SSL certificates that are mydomain.no, mydomain.se and mydomain.eu. My old config looked roughly like this: ListenHTTPS Address 81.19.246.120 Port 443 Cert "/usr/local/etc/pound.keys/mydomain.dk.pem" Service BackEnd Address 10.0.10.10 Port 8080 End End End At places like here I've seen that I can use HeadRequire in the Service part, but I want the Host header to go together with the Cert, ideally something like ListenHTTPS Address 81.19.246.120 Port 443 HostAndCert "mydomain.dk" "/usr/local/etc/pound.keys/mydomain.dk.pem" HostAndCert "mydomain.se" "/usr/local/etc/pound.keys/mydomain.se.pem" HostAndCert "mydomain.no" "/usr/local/etc/pound.keys/mydomain.no.pem" HostAndCert "mydomain.eu" "/usr/local/etc/pound.keys/mydomain.eu.pem" Service BackEnd Address 10.0.10.10 Port 8080 End End End Any suggestions or clues to how I can accomplish this? Cheers Nik

  • Perl not working with Nginx via fastcgi, cannot decipher error logs

    - by ProfessionalAmateur
    Im running CentOS 6.2, Nginx 1.2.3 following these Linode Instructions to get Perl to work with Nginx I've done everything upto the point of testing an actual Perl file. When I do this the browser says: The page you are looking for is temporarily unavailable. Please try again later. And my Nginx error-log shows the following: 2012/09/02 22:09:58 [error] 20772#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.1.102, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:8999", host: "192.168.1.10:81" Im stuck at this point. Im not sure if it matters but I also have spawn-fcgi and php-fpm to serve up PHP files on this site, but that should be 100% seperate from the perl-fastcgi setup, different port, etc.. How can I troubleshoot this?

  • How rotate TomCat 6 logs on Windows every night

    - by Danilo Brambilla
    Hi all, our TomCat 6 is running on a Windows Server 2003 server producing some logs on Program Files\Apache Software Foundation\Tomcat 6.0\logs folder. Only catalina.YYYY-MM-DD.log rotates every night. Admin. Host-Manager. Jakarta. LocalHost. Manager. stderr. stdout does not roate and are dated at the last server restart date. These files are most empty and always locked. How can I set TomCat to rotate all these logs every night (if possible without server/service restart)? Thank you in advance for help.

  • Can you use a USB dongle inside a VMWare ESX Virual Machine?

    - by Keith Sirmons
    Howdy, I need to know if a USB dongle that is required as a license key for a piece of software will accessible from the physical host machine. This will be a small vSphere 4 installation targeting the quick backup and system restore capabilities of VMWare, not specifically HA, so I am not to worried about the virtual machine automatically failing over to another physical machine and the dongle not being accessible. Does ESX have the capability to map a physical USB port or device to a specific Virtual Machine? I believe this is the dongle: Sentinal Superpro USB Dongle by Rainbow Technologies Thank you, Keith

  • Ping isn't acting accurate?

    - by Earlz
    I've been trying to diagnose some latency issues with my internet connection. I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange. I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average. How does this happen? Is ping still being accurate? I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.

  • Ignoring GET parameters in Varnish VCL

    - by JamesHarrison
    Okay: I've got a site set up which has some APIs we expose to developers, which are in the format /api/item.xml?type_ids=34,35,37&region_ids=1000002,1000003&key=SOMERANDOMALPHANUM In this URI, type_ids is always set, region_ids and key are optional. The important thing to note is that the key variable does not affect the content of the response. It is used for internal tracking of requests so we can identify people who make slow or otherwise unwanted requests. In Varnish, we have a VCL like this: if (req.http.host ~ "the-site-in-question.com") { if (req.url ~ "^/api/.+\.xml") { unset req.http.cookie; } } We just strip cookies out and let the backend do the rest as far as times are concerned (this is a hackaround since Rails/authlogic sends session cookies with API responses). At present though, any distinct developers are basically hitting different caches since &key=SOMEALPHANUM is considered as part of the Varnish hash for storage. This is obviously not a great solution and I'm trying to work out how to tell Varnish to ignore that part of the URI.

  • Wildcard 'A' record overriding CNAME record

    - by user116890
    I have a Wildcard * A record for self-registration of subdomains by users on our web app. All works fine. I now need to set up an alias for support.mydomain.com to point to mydomain.freshdesk.com. I created a CNAME record as per instructions however it appears my Wildcard A record is overriding the CNAME entry. Any thoughts on how to resolve this? I need the wildcard so creating an A record for each user subdomain is not possible. Thanks.

  • Prioritize One Network Share Over Another And/Or Cap Network Share Traffic? (Windows Server 2008 R2 Enterprise)

    - by FullTimeCoderPartTimeSysAdmin
    One of my fileservers is a hyper v VM running Windows Server 2008 R2 Enterprise. The NIC in the VM maps to a 1 GB NIC on the host that is dedicated just to this VM. I have two shares on the file server. One is very important and used by a few users. The other is less important but used by many users. The issue I'm having: When a ton of users are accessing the unimportant share, it can choke out requests to the important share. What I'd like to do: I'd like to some prioritize requests for for file on the more important share, or even dedicate a portion of the NIC's bandwidth just to requests for files on that share. Is there any way to do that? Alternately, can I add another NIC and specify that all traffic to one share goes over one NIC and traffic to the other share goes over the other?

  • How do I objectively measure an application's load on a server

    - by Joe
    All, I'm not even sure where to begin looking for resources to answer my question, and I realize that speculation about this kind of thing is highly subjective. I need help determining what class of server I should purchase to host a MS Silverlight application with a MSSQL server back-end on a Windows Server 2008 platform. It's an interactive program, so I can't simply generate a list of URLs to test against, and run it with 1000 simultaneous users. What tools are out there to help me determine what kind of load the application will put on a server at varying levels of concurrent users? Would you all suggest separating the SQL server form the web server, to better differentiate the generated load on the different parts of the stack?

  • Reverse Engineer a .pyo python file

    - by Brian
    I have 2 .pyo python files that I can convert to .py source files, but they don't compile perfectly as hinted by decompyle's verify. Therefore looking at the source code, I can tell that config.pyo simply had variables in in an array: ADMIN_USERIDS = [116901, 141, 349244, 39, 1159488] I would like to take the original .pyo and disassembly or whatever I need to do inorder to change one of these IDs. Or.... in model.pyo the source indicates a if (productsDeveloperId != self.getUserId()): All I would want to do is hex edit the != to be a == .....Simple with a windows exe program but I can't find a good python disassembler anywhere. Any suggestions are welcomed...I am new to reading bytecode and new to python as well.

  • How to bind Apache to specific IP and port on Windows Server 2008

    - by webworm
    I have a Windows Server 2008 R2 that I use to host various ASP.NET applications under IIS7. I would also like to run various PHP based web apps using Apache (or Apache 2). The server has three static IP addresses assigned to it and I would like to bind one of the IP addresses to Apache while using the other two IP addresses for IIS. I can use the IIS Manager to bind the specific IP addresses to IIS, but I am unaware of how to do this with Apache. Can anyone tell me how to go about binding Apache to a specific IP address and port (port 80 is what I want to use). Please note .. I am aware that PHP can run under IIS. In fact that is how I have been running my PHP web applications. However, there are so many inconsistencies and pitfalls with PHP running under IIS that I just prefer to use Apache.

  • "Reboot and select proper boot device"?

    - by overtherainbow
    Hello I didn't find the answer in Clonezilla's site/mailing list archives. Maybe someone has already seen this issue and knows how to recover from it: On a test host, using www.partedmagic.com, I created two partitions: One to hold an OS I wish to use for testing (/sda1), and a second partition to hold images (/sda2) After trying out Windows7, I used CloneZilla to restore an XPSP3 image, but I get the following error message when rebooting: "Reboot and select proper boot device" Could it be that Clonezilla didn't save/restore the MBR? Gparted didn't let me set a partition as "active", so it could also be this, but I have no idea. Thank you for any help.

  • Stripping a spike from rrdtool when removespike.pl doesn't find any

    - by raccettura
    I know when rrdtool graphs (using rrdtool 1.4) network traffic and the host is restarted a spike is a pretty normal thing to see. In the past I've just run that removespike.pl script that is hosted by the author and it strips the spike and I'm good to go. The last few times I've rebooted removespike.pl finds no spikes, but it's obvious that there are spikes. So my question is, how can I easily remove these spikes and get my graphs usable again? Right now it's so skewed it's meaningless.

  • Is that possible to route all mails sent to a mailbox to another server's mailbox

    - by Chau Chee Yang
    I have a Linux server that has local mail service. There are few user accounts on this server. User may send the mail to each other but that only restrict to LAN environment only. For example, I may # mail user1 to send mail to user1. User are not able to send mail to public. Some service like hylafax using this local mail service to send notification of fax status. I don't want to manage and maintain local mail service anymore. I have subscribed a package from ISP to host a public domain of my own. I wish to have my hylafax service to able to send the notification mails to public mail server, is that possible to do it? It is great if all mails that send to local mail server may forward to public mail server. That makes the local mail service serve mail forward only.
