• how to change interface ip in ifconfig with /etc/network/interfaces

  - by user2478348

  Hi everybody when modifiying /etc/network/interfaces, saving it and then executing ifconfig i can't see the modification i made..for example here is part of my /etc/network/interfaces: auto wlan1 iface wlan1 inet static address 192.168.0.60 netmask 255.255.255.0 gateway 192.168.0.61 you can see that the IP address of my wlan1 is 192.168.0.60 but when typing ifconfig i have this: wlan1 Link encap:Ethernet HWaddr 00:19:70:0f:c2:9c inet adr:192.168.0.1 Bcast:192.168.0.255 Masque:255.255.255.0 adr inet6: fe80::219:70ff:fe0f:c29c/64 Scope:Lien UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Packets reçus:758 erreurs:0 :0 overruns:0 frame:0 TX packets:610 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:1000 Octets reçus:73490 (73.4 KB) Octets transmis:127883 (127.8 KB) (the inet adr:192.168.0.1 and not 198.168.0.60)..if someone can help me I'll be very thankful :)

  After installing Ubuntu 12.04 a week ago wireless internet had been working fine. It stopped working yesterday, however, and I'm at a loss for what to do even after scouring replies to similar posted problems. I have tried using Google's public DNS and turning off proxy settings on Firefox. I have used nm-tool and lshw to make sure my wireless device and driver are connected.

• Very High Network out in ec2 instance

  - by Jatin

  I launched an ubuntu-14.04-64bit instance in Amazon EC2 two days back. And I started Tomcat 7.0.54 in that instance and deployed my application war files. It has no other software installed other than tomcat and the default ones. In the past 2 days, its shows 858 GB of Data Transfer(Network Out) from that instance. I have attached a graph of Amazon CloudWatch Metric "Network Out" My application does not do any data download/upload. Its a Java Spring application and the front end is in HTML&Javascript. My application traffic was very low (less than 20 hits) in those 2 days. Is there a way to find out why these data transfers happened and also to find what data has been transferred. If you can see in graph, network out was 20gb per minute. Some more info: Network in was negligible CPU Utilization was very high Everything else was low

• Google Analytics: How long does it take users to trigger an event

  - by Stephen Ostermiller

  I implemented Google Analytics event tracking on my currency conversion website. The typical user flow is: User lands on a page about two currencies. User enters an amount to be converted. The site shows the user the value in the other currency. The JavaScript sends Google Analytics an "converted" event when the currency conversion is done. Because most of the sessions on my site are single page, the event tracking is very important to me to be able to know if users find my page useful. I'm looking for a way to be able to figure out how long it typically takes users to enter a value in the form. I expect that this data would form a bell curve with around a specific amount of time after page load. If I can't get a graph, I could make do with a median value. I would like to be able to use this as a core metric around usability testing. Is there a way to get this information out of Google Analytics?

• Internet unusably slow with Realtek Semiconductor Co., Ltd. RTL8111/8168B card

  - by user42424

  So I have recently installed Ubuntu 11.10 for a dual boot with wind 7. After the install I had like 300 updates, so I installed them. At first I could use the internet, although it was extremely slow. However now I cannot, sometimes it will load and others it will simply time out. When I try to download something it will either take forever or will not at all. This is a wired system. On Windows side my speeds are fine. Any help would be greatly appreciated. Also like I said I am new to Linux/Ubuntu so please be nice. One last thing, I also installed 11.10 for same dual boot on my laptop, and wireless speed is the same as on Windows? Only the wired desktop gives me the problem? Hear is some hardware info.. Hope it helps.

• How to Configure Different Gateways for Different VLANs

  - by Bryan

  I have around 10 VLANs, and two different internet gateways. I want traffic on some VLANs to use one gateway, and traffic on other VLANs to use another gateway. (e.g. I wish to route server traffic via one gateway and desktop internet traffic down another). Is it possible to configure different default routes for different VLANs on a Dell 6224 switch? Or is their a better way of doing what I'm trying to achieve? The core switch I am using is a Dell PowerConnect 6224 switch. Currently I'm using: ip route 0.0.0.0 0.0.0.0 10.58.3.16 which creates the default gateway for all VLANs. I did consider adding multiple routes with equal metric, and setting ACLs between the VLANs to deny access to the 'wrong' gateway, but that idea just doesn't feel right to me.

• monitoring load on AWS EC2

  - by hortitude

  I'm interesting in monitoring our EC2 instances to ensure we scale up when necessary. Right now we are monitoring idle CPU time as our metric. We aren't measuring disk IO as we are not a very disk intensive application. When running on our own hardware in a datacenter I also usually monitor "load" from the top command. My question is: Does it make sense to monitor "load" on a shared env such as EC2? If so, how do you interpret the results?

• Is Page-Loading Time Relevant?

  - by doug

  Take this (ServerFault) page for instance. It has about 20 elements. When the last of these has loaded, the page is deemed "loaded"--but not before. This is certainly the protocol used by our testing service (which is among the small group of well-known vendors that offer that sort of service). Obviously this method is based on a clear, definite endpoint--therefore it's easy to apply w/ concomitant reliability. I think it's also the metric used by the popular Firefox plugin, 'YSlow.' For my employer's website, nearly always the last-to-load items are tracking code, tracking pixels, etc., so from the user's point of view--their perception--the page was "loaded" well before it had actually loaded based on the criterion used by our testing service (15-20% is a rough estimate). I'm sure i'm not the first person to consider this nor the first to wonder if it is causing micro-optimization while ignoring overall system-level, or user-perceived performance. So my question is, are there are other more practical (yet still reasonably precise) measures of page loading time?

• How do I know if my disks are being hit with too many I/O reads or writes or both?

  - by Mark F

  I know a bit about disk I/O and bottlenecks relating to this especially when relating to databases. How do I really know what the max I/O numbers will be for my disks? What metric might be available to me for working out roughly (but needs to be a good approximation) of how much capacity (if you will) have I got left available in I/O. I've seen it before where things are bubbling along nicely and then all of a sudden, everything screams to a halt, and it ends up being an I/O bound problem. Is there a better way to predict when I/O is reaching its limits? This article was interesting but not giving the answer I desire. So, is my best bet surrounding just looking at 'CPU I/O WAIT'? There must be a more reactive method than this.

• How to configure dnsmasq to forward multiple DNS servers?

  - by xiaoyi

  I'm now using public DNS over VPN to avoid some DNS pollution in China. But this come with a price that I can't take advantage of CDN. Is there a way to configure dnsmasq and let it query both DNS servers, both public one and ISP one, and return the IP with a lower metric? I knew it could be done by using server=/domain/server directive to assign a DNS server for a certain domain, but the problem is there are hundreds of them. So I have to figure out something generic. Thanks in advance.

• When NOT to use a framework

  - by Chris

  Today, one can find a framework for just about any language, to suit just about any project. Most modern frameworks are fairly robust (generally speaking), with hour upon hour of testing, peer reviewed code, and great extensibility. However, I think there is a downside to ANY framework in that programmers, as a community, may become so reliant upon their chosen frameworks that they no longer understand the underlying workings, or in the case of newer programmers, never learn the underlying workings to begin with. It is easy to become specialized to a degree that you are no longer a 'PHP programmer' (for example), but a "Drupal programmer", to the exclusion of anything else. Who cares, right? We have the framework! We don't need to know how to "do it by hand"! Right? The result of this loss of basic skills (sometimes to the extent that programmers who don't use frameworks are viewed as "outdated") is that it becomes common practice to use a framework where it is not required or appropriate. The features the framework facilitates wind up confused with what the base language is capable of. Developers start using frameworks to accomplish even the most basic of tasks, so that what once was considered a rudimentary process now involves large libraries with their own quirks, bugs, and dependencies. What was once accomplished in 20 lines is now accomplished by including a 20,000 line framework AND writing 20 lines to use the framework. Conversely, one does not want to reinvent the wheel. If I'm writing code to accomplish some basic, common little task, I might feel like I am wasting my time when I know that framework XYZ offers all the features I am after, and a whole lot more. The "whole lot more" part still has me worried, but it doesn't seem that many even consider it anymore. There has to be a good metric to determine when it is appropriate to use a framework. What do you consider the threshold to be, how do you decide when to use a framework, or, when not.

• Ubuntu Server 12.04 as a router. Problem with DNS?? Or Routing table?

  - by Lorenzo

  I have a virtualbox lab made up of 4 Windows 2008 R2 servers (DC/DNS,SQL,SHAREPOINT, EXCHANGE) that are configured with static ip addresses with NIC's attached to Internal network. Everything works. I had the requirement to execute some tests that also access external services available on the internet. To keep things clean and similar to the production environment I have installed another VM, with Ubuntu Server 12.04 64 bit and configured (I hope) to work as a router like described on this post. This VM has two network interfaces: first is Bridged with the host and is used as a WAN connection and the other one attached in the Internal Network with its own static IP address on the internal network subnet. But actually the Windows servers does not connect to the internet while the unix one connects. I did a route command. this is the result: Kernel IP Routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.69.121.1 0.0.0.0 UG 100 0 0 eth0 10.69.121.0 * 255.255.255.0 U 0 0 0 eth0 192.168.83.0 * 255.255.255.0 U 0 0 0 eth1 Can somebody help me with this configuration? :) Thanks! Addendum: I forgot to mention that one of the windows server hosts a DNS service for which I should maybe configure a forwarding server but I do not exactly know which server to forward on... :(

• Concurrent wireless and wired network

  - by Stew Megaw

  Hi, I am concerned with maintaining a wireless and wired network connection on my laptop. Basically I can change the metric on each interface so that Windows prefers one connection over the other. I am wondering is following scenario possible.... Some applications uses the wireless while other applications use the wired... I want Internet Explorer (only) to use the wireless connection while Outlook and everything else uses the wired connection. Perhaps adding some lines to the routing table might work? - Adding the ip addresses of websites I want to view via the wireless connection? Many Thanks in advance for any replies!

• How to map a VPN (tun0) network adapter on host Ubuntu to a VirtualBox guest Windows?

  I have a Ubuntu 10.04 running Oracle VirtualBox 3.2.6 with a Windows XP guest. I use a VPN that I would like to be accessed by the guest VM, on a ifconfig it shows as: tun0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 inet addr:5.192.10.99 P-t-P:5.192.10.99 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1362 Metric:1 RX packets:14151 errors:0 dropped:0 overruns:0 frame:0 TX packets:19860 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:4415271 (4.4 MB) TX bytes:17949982 (17.9 MB) Using NAT or Bridge adapters on the VM only gives me the non-vpn adapter.

• Configuring memcached for a particular scenario

  - by pradeepchhetri

  I have a web application which queries opentsdb server(which in backend using Hbase cluster) for the datapoints of different metrics and using dygraph javascript graphing library, I am plotting those metrics. Since getting all the datapoints of past one day from opentsdb for a particular metric is itself taking nearly 2 seconds, my application which is plotting nearly 25 metrics is becoming very slow. In order to reduce this latency, I am thinking of using memcached module of php5 for caching all the queries. But I have few questions regarding memcached. Is there any way I can configure memcache to keep on updating its cache in the background by running some command line queries after particular interval of time. Is there any way I can configure memcache to always reply for a query using cache instead of first updating its cache because my application just plots datapoints for past one day. Missing out some datapoints is not that critical.

• It is not quantifiably better

  - by MarkPearl

  An interesting statement I have heard recently in one of the organizations that I have been working with is that some of the agile processes that we are implementing are not quanitfiably better than the traditional processes they had before. This seemed to be the motivation for not moving the new process to the rest of the organization or expanding it. They would say, “the team seems to be happier than they were before but the improvement is not quanitifiable and until we can quantify it on paper we cannot make any further changes”. Up till recently I thought this was a problem until it dawned on me that their existing system was not being quantified, meaning even if I managed to quantify what we were doing (which I can), what would we be comparing it to? An appropriate response to someone when they give this reasoning is - "That's a very good point, let's go over the quantifiable attributes of your existing processes and see if we can get some common metric that we can compare them on?" If they then are able to produce some quantifiable metrics, you win because you now have something to compare it to, and if they don't then you can politely point the logic of that out as well.

• Measuring custom statistics with sar

  - by Will Glass

  I have a server application which I think is leaking file handles. I want to track the usage of file descriptors over time on my Linux (ubuntu) server. I've figured out that I can track the number of file descriptors in use by a process with lsof -p `pgrep the-process-name` | wc -l Since I'm already using sysstat and sar to track various metrics, I thought it'd be nice to display with sar. I want to measure this every 10 minutes. Is it possible to add a custom metric to sar? Then I can easily report it out. If not, I'll write a simple cron job to collect this data and store it separately in a log file.

• Secondary fallback/failover network on Cisco ASA

  - by tyranitar

  In my network there is a Cisco ASA 55x0 with "inside" interface (network 192.168.79.0/24) and "outside" interface (network 89.x.x.48/29) There is this nat rule: object network NAToutside nat (inside,outside) dynamic interface and the static route route outside 0.0.0.0 0.0.0.0 89.x.x.49 1 and all ACL rules. Now I have another new outside network by another ISP called "outside2", this network is already natted and the Cisco ASA in in the network 192.168.70.0/24. I would use this network as a fallback one. So I set the nat rule: object network NAToutside2 nat (inside,outside2) dynamic interface and the static route with a different metric route outside2 0.0.0.0 0.0.0.0 192.168.70.1 2 Clearly it doesn't work: when I disconnect the outside ethernet cable no workstation can connect to the Internet throught the outside2 network... What do I need more?

• Too many files open issue (in CentOS)

  - by Ram

  Recently I ran into this issue in one of our production machines. The actual issue from PHP looked like this: fopen(dberror_20110308.txt): failed to open stream: Too many open files I am running LAMP stack along with memcache in this machine. I also run a couple of Java applications in this machine. While I did increase the limit on the number of files that can be opened to 10000 (from 1024), I would really like to know if there is an easy way to track this (# of files open at any moment) as a metric. I know lsof is a command which will list the file descriptors opened by processes. Wondering if there is any other better (in terms of report) way of tracking this using say, nagios.
