  • How to get CVS notification emails to contain link to diff ?

    - by Ro
    Hi All, Is there any way to get CVS e-mail notifications to inlude links to my ViewCVS server where clicking a link could bring up the diff ? Currently my loginfo file just has entries like this ^installation cat | /usr/bin/Mail -s "[cvs-update installation]" [email protected] The e-mails we all then get (Afairly standard I imagine) contain the commit message and list of files changed. Cheers, Ro

  • What is the cleanest way to do a sort plus uniq on a Python list?

    - by knorv
    Consider a Python list my_list containing ['foo', 'foo', 'bar']. What is the most Pythonic way to uniqify:ing and sorting and the list (think cat my_list | sort | uniq)? This is how I currently do it and while it works I'm sure there are better ways to do it. my_list = [] ... my_list.append("foo") my_list.append("foo") my_list.append("bar") ... my_list = set(my_list) my_list = list(my_list) my_list.sort()

  • Memory Regions displayed in SMAPS output with no permissions

    - by crissangel
    If I see the output of cat /proc//smaps, I find that there are some memory regions with which no read/write/execute permissions have been associated. Also these region are mapped to inode number 0. I wanted to know how does a region end up in such a state? Is it some sort of memory leak? Can these regions be ever used again by the process?

  • How do I find everything between two characters after a word using grep, without outputting the entire line?

    - by Nick Sweeting
    I am downlading the info.0.json file from xkcd and trying to parse just the alt text. I don't care if there are quotes around it or not. The problem it that the info.0.json file is all one line, and the alt text is in quotes after the word "alt=". Trying cat info.0.json | grep alt just returns the whole file (because it's all one line). What is the grep or sed code that will get me the alt text?

  • View AccuWeather Forecasts in Google Chrome

    - by Asian Angel
    Being able to keep an eye on the weather while at work or browsing the Internet is definitely helpful. If you like detailed forecasts then join us as we take a look at the Forecastfox Weather extension for Google Chrome. Getting Started As soon as the Forecastfox Weather extension has finished installing you will automatically be presented with the “Customize Forecastfox Page”. The default setting is for New York with English measurement units. Enter your location into the blank and hit “Enter” to display the listing for your city/area. If you are presented multiple options to choose from simply click on the appropriate listing. Once you have your city/area displayed you will notice that it is possible to have access to weather forecasts for multiple locations. You can easily remove any unneeded listings with the “Remove Link”. For our example we removed the New York listing. Note: Click on desired locations and measurement units to automatically set them as defaults (no save button required). Forecastfox Weather in Action You can hover your mouse over the “Toolbar Button” to see the current weather conditions. Clicking on the “Toolbar Button” opens a popup window with the current conditions, 7 day forecast, and a static satellite image. If desired you can access additional details for the current weather conditions. Clicking on “details” opens a new tab with a nice bit of information such as UV Index, Moon Phases, Cloud Ceiling, etc. Note: AccuWeather.com webpages will have some ads displayed. Perhaps you need the Hourly Forecast… Once again a new tab will be opened with the predicted hourly weather conditions for the current day. Going back to the popup window you may also select a specific day from the 7 day forecast. You will be presented with a “Day & Night” forecast for the chosen day with links to view “Additional Details & Hourly” information. Interested in the satellite image instead? You can click on either of the available links for larger images. Once the new tab is open you can choose from a variety of different satellite images. Conclusion If you have been wanting a solid weather forecast extension for your Chrome browser then Forecastfox Weather is definitely a recommended install.

  • What Counts For a DBA – Depth

    - by Louis Davidson
    SQL Server offers very simple interfaces to many of its features. Most people could open up SSMS, connect to a server, write a simple query and see the results. Even several of the core DBA tasks are deceptively straightforward. It doesn’t take a rocket scientist to perform a basic database backup or run a trace (even using the newfangled Extended Events!). However, appearances can be deceptive, and often times it is really important that a DBA understands not just the basics of how to perform a task, but why we do a task, and how that task works. As an analogy, consider a child walking into a darkened room. Most would know that they need to turn on the light, and how to do it, so they flick the switch. But what happens if light fails to shine forth. Most would immediately tell you that you need to consider changing the light bulb. So you hop in the car and take them to the local home store and instruct them to buy a replacement. Confronted with a 40 foot display of light bulbs, how will they decide which of the hundreds of types of bulbs, of different types, fittings, shapes, colors, power and efficiency ratings, is the right choice? Obviously the main lesson the child is going to learn this day is how to use their cell phone as a flashlight so they don’t have to ask for help the next time. Likewise, when the metaphorical toddlers who use your database server have issues, they will instinctively know something is wrong, and may even have some idea what caused it, but will have no depth of knowledge to figure out the right solution. That is where the DBA comes in and attempts to save the day. However, when one looks beneath the shiny UI, SQL Server has its own “40 foot display of light bulbs”, in the form of the tremendous number of tools and the often-bewildering amount of information they can present to the DBA, to help us find issues. Unfortunately, resorting to guesswork, to trying different “bulbs” over and over, hoping to stumble on the answer. This is where the right depth of knowledge goes a long way. If we need to write a SELECT statement, then knowing the syntax and where to find the data is not enough. Knowledge of indexes and query plans is essential. Without it, we might hit on a query that “works”, but we are basically still a user, not a programmer, because we have no real control over our platform. Is that level of knowledge deep enough? Probably not, since knowledge of the underlying metadata and structures would be very useful in helping us make sense of any query plan. Understanding the structure of an index makes the “key lookup” operator not sound like what you do when someone tapes your car key to the ceiling. So is even this level of understanding deep enough? Do we need to understand the memory architecture used to process the query? It might be a comforting level of knowledge, and will doubtless come in handy at some point, but is not strictly necessary in most cases. Beyond that lies (more or less) full knowledge of SQL language and the intricacies of every step the SQL Server engine takes to process our query. My personal theory is that, as a professional, our knowledge of a given task should extend, at a minimum, one level deeper than is strictly necessary to perform the task. Anything deeper can be left to the ridiculously smart, or obsessive, or both. As an example. tasked with storing an integer value between 0 and 99999999, it’s essential that I know that choosing an Integer over Decimal(8,0) will likely offer performance benefits. It is then useful that I also understand the value of adding a CHECK constraint, to make sure the values are valid to the desired range; and comforting that I know a little about the underlying processors, registers and computer math. Anything further, I leave to the likes of Joe Chang, whose recent blog post on the topic offers depth by the bucketful!

  • RHEL - NFS4: Mounted/Exported as rw, user write permission denied

    - by brendanmac
    Hello, I have nfs4 configured between a RHEL 5.3 server (charlie) and a RHEL 5.4 client (simcom1). The machines are configured to authenticate users via kerberos by a Windows Server 2008 active directory machine called "alpha." Alpha also serves as a dns and dhcp machine for the local network. I notice that when a user logs in to a RHEL machine for the first time they are issued a unique uid to that machine; The first user to log on gets 10001. So, what I see is that users between simcom1 and charlie have different UIDs. When a user does an 'ls -la' command from within an nfs4 mount I would have thought that the usernames in the owner column would indicate 'nobody' or at least the wrong user name - since UIDs are different between the machines for each user, and not all users have logged into each machine. However, the simcom1 is able to resolve usernames in an 'ls -la' executed on files residing on charlie via nfs4 correctly. Most troubling is that users are unable to write to files across the nfs mount. The server, charlie, has the root directory exported as rw. The client, simcom1, mounts the export as rw. My configurations are shown below. My question is, how do I configure the RHEL machines to allow users to write files across nfs4 that is already mounted as read/write? [root@charlie ~]# more /etc/exports / 10.100.0.0/16(rw,no_root_squash,fsid=0) [root@charlie ~]#cat /etc/sysconfig/nfs # # Define which protocol versions mountd # will advertise.

  • Where's the Swap File/Partition?

    - by chrisbunney
    I'm investigating the virtual memory configuration of a Debian based Amazon EC2 instance, and as my background isn't in system admin, I'm slightly confused by what I'm seeing. We're using MongoDB, and the monitoring server we have indicates that the Mongo process is using about 20GB of swap space, however I can't figure out where this is located on the server. As far as I can tell from using the various suggested methods from Google, there is either a much smaller amount, or none at all. top indicates that there is 1.8GB of swap memory: top - 15:35:21 up 6 days, 3:23, 1 user, load average: 1.60, 1.43, 1.37 Tasks: 47 total, 2 running, 45 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0%us, 1.3%sy, 0.0%ni, 14.7%id, 83.8%wa, 0.0%hi, 0.0%si, 0.1%st Mem: 3928924k total, 2855572k used, 1073352k free, 640564k buffers Swap: 0k total, 0k used, 0k free, 1887788k cached swapon -s doesn't seem to think there's any swap space: Filename Type Size Used Priority free -m doesn't think there's any swap either: total used free shared buffers cached Mem: 3836 3663 172 0 626 2701 -/+ buffers/cache: 336 3500 Swap: 0 0 0 And neither does vmstat: procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 3 0 66224 641372 2874744 0 0 21 5012 21 33 2 2 76 19 But cat /etc/fstab thinks there is a swap partition: /dev/xvda1 / ext3 defaults 1 1 /dev/xvda2 /mnt ext3 defaults 0 0 /dev/xvda3 swap swap defaults 0 0 none /proc proc defaults 0 0 none /sys sysfs defaults 0 0 However df -k gives no indication of the xvda3 partition: Filesystem 1K-blocks Used Available Use% Mounted on /dev/xvda1 16513960 15675324 0 100% / tmpfs 1964460 8 1964452 1% /lib/init/rw udev 1914148 28 1914120 1% /dev tmpfs 1964460 4 1964456 1% /dev/shm So I really don't know what to make of this, because I appear to have a process using about 10 times more virtual memory than what might be available, and I have no idea where this virtual memory is on the system. I'm probably misinterpreting the output of the tools, so I'd be grateful if someone would be able to set me straight: What have I got wrong, what's the right interpretation, and how do you reach that interpretation? EDIT0: We use 10gen's MMS for monitoring the database, the relevant section for memory from the last data point is: "mem": { "virtual": 20749, "bits": 64, "supported": true, "mappedWithJournal": 20376, "mapped": 10188, "resident": 1219 }, This JSON is specific to the database process (I believe) rather than the system as a whole. fdisk -l /dev/xvda outputs... nothing? I tried each of the 3 xvda entries in /etc/fstab as well: root@ip:~# fdisk -l /dev/xvda1 Disk /dev/xvda1: 34.4 GB, 34359738368 bytes 255 heads, 63 sectors/track, 4177 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/xvda1 doesn't contain a valid partition table root@ip:~# fdisk -l /dev/xvda2 root@ip:~# fdisk -l /dev/xvda3 root@ip:~# Edit1: Output of cat /proc/meminfo for the sake of completeness: MemTotal: 3928924 kB MemFree: 726600 kB Buffers: 648368 kB Cached: 2216556 kB SwapCached: 0 kB Active: 1945100 kB Inactive: 994016 kB Active(anon): 60476 kB Inactive(anon): 12952 kB Active(file): 1884624 kB Inactive(file): 981064 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 0 kB SwapFree: 0 kB Dirty: 387180 kB Writeback: 0 kB AnonPages: 73380 kB Mapped: 1188260 kB Shmem: 48 kB Slab: 149768 kB SReclaimable: 146076 kB SUnreclaim: 3692 kB KernelStack: 1104 kB PageTables: 16096 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 1964460 kB Committed_AS: 305572 kB VmallocTotal: 34359738367 kB VmallocUsed: 16760 kB VmallocChunk: 34359721448 kB HardwareCorrupted: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 3932160 kB DirectMap2M: 0 kB

  • Kernel panic when bringing up DRBD resource

    - by sc.
    I'm trying to set up two machines synchonizing with DRBD. The storage is setup as follows: PV - LVM - DRBD - CLVM - GFS2. DRBD is set up in dual primary mode. The first server is set up and running fine in primary mode. The drives on the first server have data on them. I've set up the second server and I'm trying to bring up the DRBD resources. I created all the base LVM's to match the first server. After initializing the resources with `` drbdadm create-md storage I'm bringing up the resources by issuing drbdadm up storage After issuing that command, I get a kernel panic and the server reboots in 30 seconds. Here's a screen capture.

  • VirtualBox - Public Static IP for a Debian Guest on a Dedicated Server

    - by user86296
    Goal: I want to run a Debian-squeeze-Guest in VirtualBox and it's own public static ip. I found tons of threads about this topic, but all in all I'm now trying for 10 hours (reading the manual, the forums, trying to learn about networking concepts & commands) to give a Guest his own public static ip (so that the Guest is similar to a vServer you can order from a hosting company), but wasn't able to. Since I'm a big noob as far as networking stuff is concerned, I'm probably doing something wrong.(please bear with me :-) ) Situation: VirtualBox 4.0.10 (headless no gui) is running on a dedicated Debian-Server, the Guest OS is Debian as well. The server has a static ip and I ordered an additional ip for a VM. Problem description: Upto now I was able to use NAT to access the VM from the outside and to setup an internal network between several Guests and all of this worked very well. When setting NIC 1 to bridged and configuring a public static ip on the guest, the guest was unpingable. (neither from outside, nor from the host) I could connect to the guest via the internal network, from another vm, though. ( VBoxManage controlvm VMGuest nic1 bridged eth0 ) ( configuration attempt of static-ip on the guest '/etc/network/interfaces' is below) Please let me know what I'm doing wrong, or what I can try to get it to work, or if you need more info. I think I've read that with a current VirtualBox-version for bridged networking no special host-configuration is necessary, is that accurate, or might that be the problem? Additional Info Info I got from the hosting company about the additional IP Please note that you can use the IP address only for this server.
