  • Does anyone really understand how HFSC scheduling in Linux/BSD works?

    - by Mecki
    I read the original SIGCOMM '97 PostScript paper about HFSC, it is very technically, but I understand the basic concept. Instead of giving a linear service curve (as with pretty much every other scheduling algorithm), you can specify a convex or concave service curve and thus it is possible to decouple bandwidth and delay. However, even though this paper mentions to kind of scheduling algorithms being used (real-time and link-share), it always only mentions ONE curve per scheduling class (the decoupling is done by specifying this curve, only one curve is needed for that). Now HFSC has been implemented for BSD (OpenBSD, FreeBSD, etc.) using the ALTQ scheduling framework and it has been implemented Linux using the TC scheduling framework (part of iproute2). Both implementations added two additional service curves, that were NOT in the original paper! A real-time service curve and an upper-limit service curve. Again, please note that the original paper mentions two scheduling algorithms (real-time and link-share), but in that paper both work with one single service curve. There never have been two independent service curves for either one as you currently find in BSD and Linux. Even worse, some version of ALTQ seems to add an additional queue priority to HSFC (there is no such thing as priority in the original paper either). I found several BSD HowTo's mentioning this priority setting (even though the man page of the latest ALTQ release knows no such parameter for HSFC, so officially it does not even exist). This all makes the HFSC scheduling even more complex than the algorithm described in the original paper and there are tons of tutorials on the Internet that often contradict each other, one claiming the opposite of the other one. This is probably the main reason why nobody really seems to understand how HFSC scheduling really works. Before I can ask my questions, we need a sample setup of some kind. I'll use a very simple one as seen in the image below: Here are some questions I cannot answer because the tutorials contradict each other: What for do I need a real-time curve at all? Assuming A1, A2, B1, B2 are all 128 kbit/s link-share (no real-time curve for either one), then each of those will get 128 kbit/s if the root has 512 kbit/s to distribute (and A and B are both 256 kbit/s of course), right? Why would I additionally give A1 and B1 a real-time curve with 128 kbit/s? What would this be good for? To give those two a higher priority? According to original paper I can give them a higher priority by using a curve, that's what HFSC is all about after all. By giving both classes a curve of [256kbit/s 20ms 128kbit/s] both have twice the priority than A2 and B2 automatically (still only getting 128 kbit/s on average) Does the real-time bandwidth count towards the link-share bandwidth? E.g. if A1 and B1 both only have 64kbit/s real-time and 64kbit/s link-share bandwidth, does that mean once they are served 64kbit/s via real-time, their link-share requirement is satisfied as well (they might get excess bandwidth, but lets ignore that for a second) or does that mean they get another 64 kbit/s via link-share? So does each class has a bandwidth "requirement" of real-time plus link-share? Or does a class only have a higher requirement than the real-time curve if the link-share curve is higher than the real-time curve (current link-share requirement equals specified link-share requirement minus real-time bandwidth already provided to this class)? Is upper limit curve applied to real-time as well, only to link-share, or maybe to both? Some tutorials say one way, some say the other way. Some even claim upper-limit is the maximum for real-time bandwidth + link-share bandwidth? What is the truth? Assuming A2 and B2 are both 128 kbit/s, does it make any difference if A1 and B1 are 128 kbit/s link-share only, or 64 kbit/s real-time and 128 kbit/s link-share, and if so, what difference? If I use the seperate real-time curve to increase priorities of classes, why would I need "curves" at all? Why is not real-time a flat value and link-share also a flat value? Why are both curves? The need for curves is clear in the original paper, because there is only one attribute of that kind per class. But now, having three attributes (real-time, link-share, and upper-limit) what for do I still need curves on each one? Why would I want the curves shape (not average bandwidth, but their slopes) to be different for real-time and link-share traffic? According to the little documentation available, real-time curve values are totally ignored for inner classes (class A and B), they are only applied to leaf classes (A1, A2, B1, B2). If that is true, why does the ALTQ HFSC sample configuration (search for 3.3 Sample configuration) set real-time curves on inner classes and claims that those set the guaranteed rate of those inner classes? Isn't that completely pointless? (note: pshare sets the link-share curve in ALTQ and grate the real-time curve; you can see this in the paragraph above the sample configuration). Some tutorials say the sum of all real-time curves may not be higher than 80% of the line speed, others say it must not be higher than 70% of the line speed. Which one is right or are they maybe both wrong? One tutorial said you shall forget all the theory. No matter how things really work (schedulers and bandwidth distribution), imagine the three curves according to the following "simplified mind model": real-time is the guaranteed bandwidth that this class will always get. link-share is the bandwidth that this class wants to become fully satisfied, but satisfaction cannot be guaranteed. In case there is excess bandwidth, the class might even get offered more bandwidth than necessary to become satisfied, but it may never use more than upper-limit says. For all this to work, the sum of all real-time bandwidths may not be above xx% of the line speed (see question above, the percentage varies). Question: Is this more or less accurate or a total misunderstanding of HSFC? And if assumption above is really accurate, where is prioritization in that model? E.g. every class might have a real-time bandwidth (guaranteed), a link-share bandwidth (not guaranteed) and an maybe an upper-limit, but still some classes have higher priority needs than other classes. In that case I must still prioritize somehow, even among real-time traffic of those classes. Would I prioritize by the slope of the curves? And if so, which curve? The real-time curve? The link-share curve? The upper-limit curve? All of them? Would I give all of them the same slope or each a different one and how to find out the right slope? I still haven't lost hope that there exists at least a hand full of people in this world that really understood HFSC and are able to answer all these questions accurately. And doing so without contradicting each other in the answers would be really nice ;-)

  • Trouble setting up PATH for Java on Debian

    - by milkmansrevenge
    I am trying to get Oracle Java 7 update 3 working correctly on Debian 6. I have downloaded and set up the files in /usr/java/jre1.7.0_03. I have also set the following two lines at the end of /etc/bash.bashrc: export JAVA_HOME=/usr/java/jre1.7.0_03 export PATH=$PATH:$JAVA_HOME/bin Logging in as other users and root is fine, Java can be found: chris@mc:~$ java -version java version "1.7.0_03" Java(TM) SE Runtime Environment (build 1.7.0_03-b04) Java HotSpot(TM) 64-Bit Server VM (build 22.1-b02, mixed mode) However there are two cases where Java cannot be found as detailed below. Note that both of these worked fine when I have previously installed OpenJDK Java 6 via aptitude, but I need Oracle Java 7 for various reasons. Most importantly, I cannot run commands as another user via su, despite the PATH showing that Java should be present. The user was created with adduser chris root@mc:~# su chris -c "echo $PATH" /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/java/jre1.7.0_03/bin:/bin root@mc:~# su chris -c "java -version" bash: java: command not found root@mc:~# su chris -c "/usr/java/jre1.7.0_03/bin/java -version" java version "1.7.0_03" ... How can it be in the PATH but not be found? Update 05/04/2012: explained by Daniel, to do with it being a non-interactive shell so files such as /etc/profile and /etc/bash.bashrc are not executed. Doing a full swap to that user and running Java works: root@mc:~# su chris chris@mc:/root$ java -version java version "1.7.0_03" ... I run a script on start up which exhibits similar but slightly different problems. The script is located in /etc/init.d/start-mystuff.sh and calls a jar: #!/bin/bash # /etc/init.d/start-mystuff.sh java -jar /opt/Mars.jar I can confirm that the script runs on start up and the exit code is 127, which indicates command not found. Inserting a line to print/save the PATH shows that it is: /sbin:/usr/sbin:/bin:/usr/bin This second problem isn't as important because I can just point directly to the Java executable in the script, but I am still curious! I have tried setting the full PATH and JAVA_HOME explicitly in /etc/environment which didn't help. I have also tried setting them in /etc/profile which doesn't seem to help either. I have tried logging in and out again after setting PATH in the various locations (duh!). Anyway, long post for what will probably have a simple one line solution :( Any help with this would be greatly appreciated, I have spent far too long trying to fix it by myself. Motivation The first problem may seem obscure but in my system I have users that are not allowed SSH access yet I still want to run processes as them. I have a ton of scripts operating in this way and don't want to have to change them all.

  • Tool to compute SHA256 Tree Hash

    - by Benjamin
    I've started using AWS Glacier, and noticed that it hashes the files using an algorithm called SHA-256 Tree Hash. To my surprise, this algorithm is different from SHA-256, so I can't use the tools I'm used to, to compare hashes and verify file integrity. Do you know a Windows tool, if possible integrated in the context menu, to compute the SHA-256 Tree Hash of a file? I'd also accept a Linux command-line tool, as a second choice :-)

  • Get tarball of any public SVN repository

    - by Sridhar Ratnakumar
    Is there a website that allows one to get the tarball of any specified SVN repository? For example I want to get the tarball or zip of http://svn.python.org/view/python/trunk/ without having to use a local SVN client, but only use my browser or some command line HTTP client (such as wget). This is mainly for some old unix machines that do not have SVN client.

  • How does Windows Task Scheduler detect that a task is already running?

    - by Dan C
    I have an application on Windows Server 2008 that takes different command-line parameters. For example: myapp.exe /A myapp.exe /B I have created a task scheduler task for each of those. While "myapp.exe /A" is running, I want to prevent another instance of it from starting. However, I still want "myapp.exe /B" to be able to run (again, though only one instance of it at a time). How can I set this up?

  • sendmail on ubuntu (9.10) machine "stopped" sending mail

    - by Doron
    I'm developing on my ubuntu 9.10 machine for the web (php). I'm using it sendmail for sending mails, and while developing on my local machine, I send local mails (to my user 'doron'). Up until a few days ago, I was able to send mails both from php's mail() function, and from the command line using the mail command. I'm using sendmail with mailutils. Since the last few days, it seems like it stopped working. When I try to send mail from the command line, I get the following in my syslog (and mail.info, and mail.log): Mar 3 13:27:58 doron-desktop sendmail[4693]: o23BRwlA004693: from=doron, size=84, class=0, nrcpts=1, msgid=<201003031127.o23BRwlA004693@doron-desktop.>, relay=doron@localhost Mar 3 13:27:58 doron-desktop sm-mta[4694]: o23BRwtQ004694: ruleset=check_rcpt, arg1=<doron@doron-desktop>, relay=localhost [127.0.0.1], reject=553 5.1.8 <doron@doron-desktop>...

  • Filtering Security Logs by User and Logon Type

    - by Trido
    I have been asked to find out when a user has logged on to the system in the last week. Now the audit logs in Windows should contain all the info I need. I think if I search for Event ID 4624 (Logon Success) with a specific AD user and Logon Type 2 (Interactive Logon) that it should give me the information I need, but for the life of my I cannot figure out how to actually filter the Event Log to get this information. Is it possible inside of the Event Viewer or do you need to use an external tool to parse it to this level? I found http://nerdsknowbest.blogspot.com.au/2013/03/filter-security-event-logs-by-user-in.html which seemed to be part of what I needed. I modified it slightly to only give me the last 7 days worth. Below is the XML I tried. <QueryList> <Query Id="0" Path="Security"> <Select Path="Security">*[System[(EventID=4624) and TimeCreated[timediff(@SystemTime) &lt;= 604800000]]]</Select> <Select Path="Security">*[EventData[Data[@Name='Logon Type']='2']]</Select> <Select Path="Security">*[EventData[Data[@Name='subjectUsername']='Domain\Username']]</Select> </Query> </QueryList> It only gave me the last 7 days, but the rest of it did not work. Can anyone assist me with this? EDIT Thanks to the suggestions of Lucky Luke I have been making progress. The below is my current query, although as I will explain it isn't returning any results. <QueryList> <Query Id="0" Path="Security"> <Select Path="Security"> *[System[(EventID='4624')] and System[TimeCreated[timediff(@SystemTime) &lt;= 604800000]] and EventData[Data[@Name='TargetUserName']='john.doe'] and EventData[Data[@Name='LogonType']='2'] ] </Select> </Query> </QueryList> As I mentioned, it wasn't returning any results so I have been messing with it a bit. I can get it to produce the results correctly until I add in the LogonType line. After that, it returns no results. Any idea why this might be? EDIT 2 I updated the LogonType line to the following: EventData[Data[@Name='LogonType'] and (Data='2' or Data='7')] This should capture Workstation Logons as well as Workstation Unlocks, but I still get nothing. I then modify it to search for other Logon Types like 3, or 8 which it finds plenty of. This leads me to believe that the query works correctly, but for some reason there are no entries in the Event Logs with Logon Type equalling 2 and this makes no sense to me. Is it possible to turn this off?

    I recently installed the latest drivers and my screen backlight turned off. The problem is that my Fn-F7 key combination doesn't work, so I can't turn it back on. I can see my screen at night if I hold a source of light next to the screen. So I can still do some trivial things with my laptop. Is there a way to turn the backlight on without using Fn-F7 key combination, either via the command line, or some other way?

  • Centralized logging for JBoss / log4j? [closed]

    - by mfarver
    Does anyone have advice or a pointer to articles on how to centralize logs in JBoss? JBoss will log to syslog, which makes it easy, but doing so breaks multi line debug messages (and Jboss loves dropping exception stack traces in the logs). I can rsync the logs, but that isn't realtime. Log4j has appenders for TCP and multicast sockets, so it seems like something probably exists for streaming logs, but I haven't found a receiver for the data. Thanks
