• How many bits for sequence number using Go-Back-N protocol.

  - by Mike

  Hi Everyone, I'm a regular over at Stack Overflow (Software developer) that is trying to get through a networking course. I got a homework problem I'd like to have a sanity check on. Here is what I got. Q: A 3000-km-long T1 trunk is used to transmit 64-byte frames using Go-Back-N protocol. If the propagation speed is 6 microseconds/km, how many bits should the sequence numbers be? My Answer: For this questions what we need to do is lay the base knowledge. What we are trying to find is the size of the largest sequence number we should us using Go-Back-N. To figure this out we need to figure out how many packets can fit into our link at a time and then subtract one from that number. This will ensure that we never have two packets with the same sequence number at the same time in the link. Length of link: 3,000km Speed: 6 microseconds / km Frame size: 64 bytes T1 transmission speed: 1544kb/s (http://ckp.made-it.com/t1234.html) Propagation time = 6 microseconds / km * 3000 km = 18,000 microseconds (18ms). Convert 1544kb to bytes = 1544 * 1024 = 1581056 bytes Transmission time = 64 bytes / 1581056bytes / second = 0.000040479 seconds (0.4ms) So then if we take the 18ms propagation time and divide it by the 0.4ms transmission time we will see that we are going to be able to stuff ( 18 / 0.4) 45 packets into the link at a time. That means that our sequence number should be 2 ^ 45 bits long! Am I going in the right direction with this? Thanks, Mike

• Run mplayer from bash in background without extra bash

  - by Emanuel Berg

  I would like to watch a movie with mplayer from bash in the background, like I do with all programs and there has never been any problems: mplayer Kick* & if you'd like to see Kickboxer, for example. But, this doesn't bring up the window, instead it says the process is stopped. I can bring the movie window up with fg mplayer, but then the CLI is unavailable. (This is -- as far as I can see anyway -- equivalent to mplayer Kick*). I'm able to work around the problem like this: $(mplayer Kick*) & But then I get two extra bashes (I see this with ps). It is not really a problem as those closes down when I Alt-F4 the movie, but it is still undesirable. I guess I'm most annoyed with having to type that extra stuff, so if you come up with an alias or function, that would be OK, to. Although, it wouldn't hurt me to learn what's going on. Edit: Hm, it doesn't even seem to work the way I said. The "work"around is not reliable. Forget about it.

• Django running on Apache+WSGI and apache SSL proxying

  - by Lessfoe

  Hi all, I'm trying to rewrite all requests for my Django server running on apache+WSGI ( inside my local network) and configured as the WSGI's wiki how to, except that I set a virtualhost for it. The server which from I want to rewrite requests is another apache server listening on port 80. I can manage it to work well if I don't try to enable SSL connection as the required way to connect. But I need all requests to Django server encrypted with SSL so I generally used this directive to achieve this ( on my public webserver ): Alias /dirname "/var/www/dirname" SSLVerifyClient none SSLOptions +FakeBasicAuth SSLRequireSSL AuthName "stuff name" AuthType Basic AuthUserFile /etc/httpd/djangoserver.passwd require valid-user # redirect all request to django.test:80 RewriteEngine On RewriteRule (.*)$ http://django.test/$1 [P] This configuration works if I try to load a specific page trough the external server from my browser. It is not working clicking my django application urls ( even tough the url seems correct when I put my mouse over). The url my public server is trying to serve use http ( instead of https ) and the directory "dirname" I specified on my apache configuration disappear, so it says that the page was not found. I think it depends on Django and its WSGI handler . Does anybody went trough my same problem? PS: I have already tried to modify the WSGI script . I'm Using Django 1.0.3, Apache 2.2 on a Fedora10 (inside), Apache 2.2 on the public server. Thanks in advance for your help. Fab

• Trying to run chrooted suPHP with UserDir, getting 500 server error

  - by Greg Antowski

  I've managed to get suPHP working fine with UserDir (i.e. PHP files run from the /home/$username/public_html) directory, but I can't get it to work when I chroot it to the user's home directory. I've been following this guide: http://compilefailure.blogspot.co.nz/2011/09/suphp-chroot-gotchas.html And adapting it to my needs. I'm not creating vhosts, I just want PHP scripts to be jailed to the user's home directory. I've gotten to the part where you use makejail and set up a symlink. However even with the symlink set up correctly, PHP scripts won't run. This is what's shown in the Apache error log: SoftException in Application.cpp:537: Could not execute script "/home/jimmy/public_html/test.php" [error] [client 127.0.0.1] Caused by SystemException in API_Linux.cpp:444: execve() for program "/usr/bin/php-cgi" failed: No such file or directory The thing is, if I try running either of the following commands in the terminal it works without any issues: /home/jimmy/usr/bin/php-cgi /home/jimmy/public_html/test.php /usr/bin/php-cgi /home/jimmy/public_html/test.php I've been trying for hours to get this going and documentation for this kind of stuff is almost non-existent. If anyone could help me out with this, I'd be extremely grateful.

• Router for creating site to site VPN to server provider using Cisco ASA 5540

  - by fondie

  We have dedicated servers hosted for us by a third party, we connect to these over a VPN. My server provider uses Cisco ASA 5540 as VPN devices. Currently we're using software clients on individual machines to connect to this VPN, either: Cisco VPN Client Shrew Soft VPN Connect However, I'm looking to purchase a new load balancing router for our office and thought this could be an opportunity to get VPN client duties taken over by hardware. We could then create a permanent VPN tunnel that could be used by anyone on the network with no software client necessary. Sadly I'm not the most knowledgeable on this kind of stuff so is: 1) This a realizable goal? Next I need to know what kind of hardware I will need. I'm not looking to spend lots of money on this (~$500), so doubtful I can afford any Cisco kit. Therefore, this is the most promising candidate I've seen (as far as my limited knowledge goes): Draytek Vigor 2955 - http://www.draytek.co.uk/products/vigor2955.html 2) Would this be compatible with the Cisco kit my server provider uses? 3) If not, are there any alternatives I should consider? Many thanks in advance.

• How to manage sub-domains on WinHost with IIS7 URL Rewrite 2.0?

  - by jrummell

  I'm trying out WinHost and I'm running into some issues with sub-domains. On WinHost, you can have multiple sub-domains per hosting account, but each sub-domain points to the root website. E.g. you can have www.example.com, sub1.example.com, and sub2.example.com but all of them display the content at http://www.example.com/. Other Hosts allow you to point sub-domains to a sub folder in your website. This would allow you to point sub1.example.com to /sub1, sub2.example.com to /sub2 and www.example.com to /. WinHost recommends using an asp/aspx page to redirect http://sub1.example.com to http://sub1.example.com/sub1, which points to /sub1. While that would work, I'd like to not have the subdomain in the url twice. So I tried using IIS7 URL Rewrite to point http://sub1.example.com to /sub1. Ben Powell describes this in detail on his blog. This is great, except Request.ApplicationPath is now /sub1/path/to/current/page.aspx, which breaks ASP.Net Themes (and probably other stuff too). What can I do to fix the ApplicationPath? Is there a better way to accomplish this?

• Launching a PHP daemon from an LSB init script w/ start-stop-daemon

  - by EvanK

  I'm writing an lsb init script (admittedly something I've never done from scratch) that launches a php script that daemonizes itself. The php script starts off like so: #!/usr/bin/env php <?php /* do some stuff */ It's then started like so in the init script: # first line is args to start-stop-daemon, second line is args to php-script start-stop-daemon --start --exec /path/to/executable/php-script.php \ -- --daemon --pid-file=$PIDFILE --other-php-script-args The --daemon flag causes the php script to detach & run as a daemon itself, rather than relying on start-stop-daemon to detach it. This is how it's (trying to) stop it in the init script: start-stop-daemon --stop --oknodo --exec /path/to/executable/php-script.php \ --pidfile $PIDFILE The problem is, when I try to stop via the init script, it gives me this: $ sudo /etc/init.d/my-lsb-init-script stop * Stopping My Project No /path/to/executable/php-script.php found running; none killed. ...done. A quick peek at ps tells me that, even though the php script itself is executable, its running as php <script> rather than the script name itself, which is keeping start-stop-daemon from seeing it. The PID file is even being generated, but it seems to ignore it and try to find+kill by process name instead. $ ps ax | grep '/path/to/executable/php-script.php' 2505 pts/1 S 0:01 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2507 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2508 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2509 pts/1 S 0:00 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args 2518 pts/1 S 0:01 php /path/to/executable/php-script.php --daemon --pid-file /var/run/blah/blah.pid --other-php-script-args $ cat /var/run/blah/blah.pid 2518 Am I completely misunderstanding something here? Or is there an easy way to work around this?

• How do I host node.js apps with pm2 without running them as root?

  - by jishi

  I have setup pm2 to run a node.js application, and I can successfully start it and it will resurrect upon reboot. However, the pm2 daemon is ran as root, which makes me think that all my node-scripts also runs as root? Even though I added them as a regular user in the system. The log files and stuff is created in the users home dir, /~/.pm2/logs, but the logs are owned by root. when I invoke pm2 startup (which handles the installation of the init.d script etc), it creates /etc/init.d/pm2-init.sh which looks like this: #!/bin/bash # chkconfig: 2345 98 02 # # description: PM2 next gen process manager for Node.js # processname: pm2 # ### BEGIN INIT INFO # Provides: pm2 # Required-Start: # Required-Stop: # Should-Start: # Should-Stop: # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: PM2 init script # Description: PM2 is the next gen process manager for Node.js ### END INIT INFO NAME=pm2 PM2=/usr/local/lib/node_modules/pm2/bin/pm2 NODE=/usr/local/bin/node export HOME="/root" start() { echo "Starting $NAME" $NODE $PM2 stopAll $NODE $PM2 resurrect } stop() { $NODE $PM2 dump $NODE $PM2 stopAll } restart() { echo "Restarting $NAME" stop start } status() { echo "Status for $NAME:" $NODE $PM2 list RETVAL=$? } case "$1" in start) start ;; stop) stop ;; status) status ;; restart) restart ;; *) echo "Usage: {start|stop|status|restart}" exit 1 ;; esac exit $RETVAL When I dump the processes (which is what it will use when resurrecting the processes), I see mentions of user "USER":"pi" but I don't think that it's actually run as user pi. Any thoughts?

• 32-bit Ubuntu or 64-bit w/Intel Atom D510 w/4GB RAM?

  - by T.J. Crowder

  (I've seen this question and some related ones, and perhaps this is a duplicate although part of my question is specific to the Atom D510.) I'm going to be installing Ubuntu on a new silent desktop as my latest (and hopefully last) attempt to switch from Windows to Linux for at least most everyday tasks. The new machine is entirely passvely cooled, but as a consequence, not astonishingly powerful — an Atom D510 (dual-core, 1.6GHz, HT) on Intel's D510MO board. That's fine, I won't use it for gaming, (much) video editing, etc. It's a 64-bit processor and I'm maxing the board out at 4GB of RAM (hey, that 1.6 CPU needs all the help it can get), which naturally raises the question of whether to install Ubuntu 64-bit or 32-bit (and if the latter, either live with the missing RAM, or do the PAE kernel dance). Although I've used Linux on servers for years, I'm very nearly a Linux desktop newbie and am not currently in the mood to fight driver wars and such. So if I'm setting myself up for failure with 64-bit, I'll live with the missing ~0.8GB or fiddle with PAE. But if 64-bit is entirely "ready," great, I'm there. So: Do most mainstream apps (now) play nicely with 64-bit Linux? I can't help but notice the "AMD" in the ISO image filename ubuntu-10.04-desktop-amd64.iso and I know AMD lead the way on this stuff — does Ubuntu 64-bit play nicely with Intel processors? Just generally, would you recommend one or the other? (And if anyone has any experience with Ubuntu specifically on the D510 [32-bit or 64-bit] which might lead me one way or t'other, that would be useful.) Thanks in advance.

• Excel techniques for perfmon csv log file analysis

  - by Aszurom

  I have perfmon running against several servers, where I'm outputting to a .csv file data like CPU %time, memory bytes free, hard disk I/O metrics like s/write and writes/s. The ones graphing the SQL servers are also collecting SQL stats. The web servers are collecting .Net relevant stuff. I am aware of PAL, and used it as a template of what data to capture based on server type actually. I just don't think the output it generates is detailed or flexible enough - but it does a pretty remarkable job of parsing logs and making graphs. I'm borderline incompetent with Excel, so I'm hoping to be directed to some knowledge of how to take a perfmon output .csv and mine it in Excel to produce some numbers that are meaningful to me as a sysadmin. I could of course just pick a range of data and assemble a graph out of that and look for spikes and trends, but I'm convinced there is some technique to this that makes it more manageable than looking at a monsterous spreadsheet of numbers and trying to make graphs of it. Plus, it's pretty time consuming and not something I can do as a "take a glance at the servers" sort of routine. I'm graphing CPU, disk use, network b/sec, etc. in Cacti as well, which is nice for seeing big trends. The problem is that it is 5 minute averages, so a server could have a problem but it's intermittent and washes out in a 5 min average. What do you do with perfmon data that I could learn from?

• getting a pyserial not loaded error

  - by skinnyTOD

  I'm getting a "pyserial not loaded" error with the python script fragment below (running OSX 10.7.4). I'm trying to run a python app called Myro for controlling the Parallax Scribbler2 robot - figured it would be a fun way to learn a bit of Python - but I'm not getting out of the gate here. I've searched out all the Myro help docs but like a lot in-progress open source programs, they are a moving target and conflicting, out of date, or not very specific about OSX. I have MacPorts installed and installed py27-serial without error. MacPorts lists the python versions I have installed, along with the active version: Available versions for python: none python24 python25 python25-apple python26 python26-apple python27 python27-apple (active) python32 Perhaps stuff is getting installed in the wrong places or my PATH is wrong (I don't much know what I am doing in Terminal and have probably screwed something up). Trying to find out about my sys.path - here's what I get: import sys sys.path ['', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC', '/Library/Python/2.7/site-packages'] Is that a mess? Can I fix it? Anyway, thanks for reading this far. Here's the python bit that is throwing the error. The error occurs on 'try import serial'. # Global variable robot, to set SerialPort() robot = None pythonVer = "?" rbString = None ptString = None statusText = None # Now, let's import things import urllib import tempfile import os, sys, time try: import serial except: print("WARNING: pyserial not loaded: can't upgrade!") sys.exit() try: input = raw_input # Python 2.x except: pass # Python 3 and better, input is defined try: from tkinter import * pythonver = "3" except: try: from Tkinter import * pythonver = "2" except: pythonver = "?"

• Programmable Home Security Alarm [closed]

  - by stej

  I don't ask for recommendation! (just wanted to say that; anyway it doesn't matter now as the question is closed) I've seen some advertisements about home alarms that notifies me that something is happening in my house. None of them mentioned programmability (with real programming language like e.g C, assembler, whatever). As a programmer I'd like to have a possibility to add some behaviour, that is not part of the alarm itself. This might be: take snapshots of all cameras in a house and send it to some email send email, twitter message, skype message to some predefined account send email to a police (silly, I know) start turning the lights on and off (scary, right?) etc. (would be veeery challenging with assembler, I know; but lets suppose I can use some more high level language) I don't expect that there is a alarm system capable of this stuff, that's why I'm looking for a programmable module. Question: Is it even possible? Is it good idea (my program could crash and cause instability of the system).

• The frame buffer layout of the current display cannot be made to match...

  - by adambox

  I get this error when I have VM running in VMWare Workstation on my work PC and try Remote Desktop-ing in from my iMac at home. I just upgraded VMWare Workstation to 7.0 from 6.0 and now I'm getting it when I try to resume my VM at work. It then asks me the scary question of whether I want to preserve or discard the suspended state. I don't want to lose stuff! ack! Update I backed up my VM and tried hitting that "discard" button and the result was a reboot of the VM. I then tried restoring to a snapshot, and none of my snapshots work! Is there anyway to fix this so I can run 7 but still have my old snapshots? The frame buffer layout of the current display cannot be made to match the frame buffer layout stored in the snapshot. The dimensions of the frame buffer in the snapshot are: Max width 3200, Max height 1770, Max size 22659072. The dimensions of the frame buffer on the current display are: Max width 3200, Max height 1600, Max size 20512768. Error encountered while trying to restore the virtual machine state from file "C:\Documents and Settings\adam\My Documents\My Virtual Machines\dev\Windows XP Professional.vmss". What do I do so I don't break things horribly?

• Windows 7 Sysprep Default User

  - by Demonwolf

  I seem to be having a problem with implementing my sysprep. I have been playing with Windows 7, WAIK, Server 2008 R2 and various other things. I managed to create a WIM with everything I need installed and I have worked out the autounattend.xml. I now have a Windows 7 64-bit complete unattended install from a USB device. It has all my programs, setting and everything done except one thing - the default profile set up 100% correctly. I have created a mostly set up default profile. I booted into audit mode, customized the Administrator account (mostly anyway) and then used sysprep with an unattend.xml file containing the copyprofile=true command. The file was set up with the WSIM and does not contain any extra info. This all works wonderfully. I recreated the WIM and all was good. I then decided to move the default location of the visible stuff in the user profile (Documents, Music, Pictures etc.) without changing the location of Appdata or other hidden folders. This is where things went a little... wrong. I went to the user folder (generally has the User name) with all the other folders in it. I right clicked on My Documents, found the location tab and changed it to M:\Documents. Now if I run sysprep /generalize /oobe /reboot /unattend:unattend.xml it starts the generalise... then spits out a fatal error and goes no further. The setuperr.log contains the following errors: 2011-08-18 23:21:43, Error [0x0f0043] SYSPRP WinMain:The sysprep dialog box returned FALSE 2011-08-18 23:31:57, Error [0x0f0082] SYSPRP LaunchDll:Failure occurred while executing 'C:\Windows\System32\slc.dll,SLReArmWindows', returned error code -1073425657 2011-08-18 23:31:57, Error [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = -1073425657 2011-08-18 23:31:57, Error [0x0f00a8] SYSPRP WinMain:Hit failure while processing sysprep generalize internal providers; hr = 0xc004d307 Does anyone have any ideas how I can redirect My Documents and other items in a user file to a second drive in the default profile so it affects each person logging in?

• Weird "missing" CD/DVD driver during Windows Server 2008 installation

  - by Django Reinhardt

  Hi. We have an old PowerEdge 860 that we're trying to install Windows Server 2008 R2 onto. At present the machine doesn't have any OS installed, so we're doing a clean install from a DVD. Pretty simple stuff. The problem is that, although the installation process starts off well (asking for language and locale settings), as soon as we click "Install Now" we're told "A required CD/DVD device driver is missing." The operating system has already booted from our only DVD drive(!). I've seen other people complain about this problem (usually in relation to installing Vista or Windows 7) but I've not found a 100% solution yet. (Our DVD drive is a Hitachi LG GWA-4400N, salvaged from an old laptop. There have never been any drivers released for this device, nor any firmware updates.) The most promising lead I have is from someone claiming that Windows is actually asking for a driver for the ATAPI/IDE Controller here. UPDATE See my answer below... It was most likely a corrupt download. (*shame*) I will update this question when I know for sure.

• How to troubleshoot web server lock-up (Debian Squeeze)

  - by Ryan

  Every once in a while, my web server slows so significantly, it seems locked up. Can't SSH in, no sites being served. It's a VPS that started out as Debian 5 which I upgraded to testing (squeeze). It's a typical LAMP set-up with the sole purpose of running a couple of wordpress sites. One time when it locked up, I got to one of the sites, but it was wordpress complaining it couldn't establish a database connection. So it seemed as if something was really chewing up the CPU and mysqld either timed out, or possibly failed and couldn't restart. But since I couldn't SSH in I feel more inclined to attribute it to CPU. But the only processes running now, aside from OS and kernel stuff: apache mysqld python (for fail2ban) sshd exim4 It has 512M of RAM and 1.5 GB of swap. Every time I check on it, it has plenty of free memory and is using virtually no swap (usually 2-3M). And since I am running fail2ban I don't think I'm getting ddosed. I did find this in my logwatch email this morning (it locked up late last night, when there would have been very little traffic): 6 Time(s): [<ffffffff810a0ebc>] ? oom_kill_process+0x7e/0x23d 6 Time(s): [<ffffffff810a1505>] ? __out_of_memory+0x12a/0x141 6 Time(s): [<ffffffff810a1586>] ? out_of_memory+0x6a/0x94 I didn't find anything else suspicious. It can't be my provider's host because I can SSH in and restart the VM, and everything seems fine. Anybody know which logs I should start poring through to find the core of my problem? Thanks guys.

• Web based KVM management for Ubuntu

  - by Tim

  Hey all, We've got a single Ubuntu 9.10 root server on which we want to run multiple KVM virtual machines. To administer these virtual machines I'd like a web based KVM management tool, but I don't know which one to choose from the list of tools mentioned on linux-kvm.org. I've used virsh & virt-manager on my desktop, but would like a web interface for the server. I tested ConVirt on my desktop, but it failed to pickup KVM machines from virsh / virt-manager, and I could not get KVM virtual machine import to work (only Xen). oVirt looks good, but I can't find out if and how I can install it on Ubuntu 9.10.. (And I'd really rather not waste another few days on testing stuff that might not work in the end.) Can anyone recommend any good web based KVM management tools that are easy to install on Ubuntu 9.10? I'm looking for something that will also allow me to run other services like apache and postgresql besides hosting virtual machines, so preferably fairly lightweight & no dedicated OS installs. We don't need any professional clustering / migration or anything, just something that will let us create, start, inspect, administer & stop virtual machines from a web page. Best regards, Tim

• most reliable linux terminal app / general procedures for process stability

  - by intuited

  I've been using konsole (KDE 4.2) for a while now but it crashed recently. Konsole is efficiently designed to use one instance for all of the windows for your entire X session. Extra-unfortunately, because of this ingenuity the crash brought down all the humpty-dumptys and their bashes and their bashes' applications and all the begattens' begattens all the way down to Jebodiah Springfield into one big flat nonexistent omelette. The fact that this app is capable of crashing under any circumstances is pretty disappointing. Although KDE 4.2 is not expected to be entirely stable -- and yes, I know, I should update my distro -- it's still a no-sell for me, since if at all possible, this sort of thing Shouldn't Happen to something that's likely to be a foundation for an entire working environment. Maybe this is arrogant and unrealistic, but if it's possible to have something more stable, I want it. So other than running under screen -- which is fun, nifty, and thus far flawless in its reliability, but which has some issues with not understanding certain keycodes -- I'm looking for ways to improve my environment's reliability. The most obvious strategy is to cast about for a more reliable console app. A standard featureset -- which to me includes tabbed windows, Unicode support, and a decent level of keyboard shortcut configuration -- is pretty much essential. I'm currently running gnome-terminal and roxterm, both of which have acceptable featuresets (pretty much identical, actually; I think rox is actually the superset), and neither of which have provided me with extensive, objective reliability data. Not that they were expected to. Other strategies are also welcome. Were I responding to this question I would perhaps suggest backgrounding critical tasks with & and/or disowning them so they don't come down with the global pandemic. And stuff like that.

• How can I install Satchmo?

  - by Jonathan Hayward

  I am trying to install Satchmo 0.9 on an Ubuntu 9.10 guest off of the instructions at http://bitbucket.org/chris1610/satchmo/downloads/Satchmo.pdf. I run into difficulties at 2.1.2: pip install -r http://bitbucket.org/chris1610/satchmo/raw/tip/scripts/requirements.txt pip install -e hg+http://bitbucket.org/chris1610/satchmo/@v0.9#egg=satchmo The first command fails because a compile error for how it's trying to build PIL. So I ran an "aptitude install python-imaging", locally copy the first line's requirements.text, and remove the line that's unsuccessfully trying to build PIL. The first line completes without error, as does the second. The next step tells me to change directory to the /path/to/new/store, and run: python clonesatchmo.py A little bit of trouble here; I am told that clonesatchmo.py will be in /bin by now, and it isn't there, but I put some Satchmo stuff under /usr/local, create a symlink in /bin, and run: python /bin/clonesatchmo.py This gives: jonathan@ubuntu:~/store$ python /bin/clonesatchmo.py Creating the Satchmo Application Traceback (most recent call last): File "/bin/clonesatchmo.py", line 108, in <module> create_satchmo_site(opts.site_name) File "/bin/clonesatchmo.py", line 47, in create_satchmo_site import satchmo_skeleton ImportError: No module named satchmo_skeleton A find after apparently checking out the repository reveals that there is no file with a name like satchmo*skeleton* on my system. I thought that bash might be prone to take part of the second pip invocation's URL as the beginning of a comment; I tried both: pip install -e hg+http://bitbucket.org/chris1610/satchmo/@v0.9\#egg=satchmo pip install -e hg+http://bitbucket.org/chris1610/satchmo/@v0.9#egg=satchmo Neither way of doing it seems to take care of the import error mentioned above. How can I get a Satchmo installation under Ubuntu, or at least enough of a Satchmo installation that I am able to start with a skeleton of a store and then flesh it out the way I want? Thanks, Jonathan

• Samba Server Make Multiple User Permissions Profiles

  - by Scriptonaut

  I have a Samba file server running, and I was wondering how I could make multiple user accounts that have different permissions. For example, at the moment I have a user, smbusr, but when I ssh to the share, I can read, write, execute, and even navigate out of the samba directory and do stuff on the actual computer. This is bad because I want to be able to give out my IP so friends/family can use the server, but I don't want them to be able to do just anything. I want to lock the user in the samba share directory(and all the sub directories). Eventually I would like several profiles such as (smbusr_R, smbusr_RW, smbguest_R, smbguest_RW). I also have a second question related to this, is SSH the best method to connect from other unix machines? What about VPN? Or simply mounting like this: mount -t ext3 -o user=username //ipaddr/share /mnt/mountpoint Is that mounting command above the same thing as a vpn? This is really confusing me. Thanks for the help guys, let me know if you need to see any files, or need anymore information.

• pros and cons with server management gui tools to manage linux web servers

  - by ajsie

  i have stumbled upon these GUI tools that could help you manage your linux server through a web interface. ebox, webmin, ispconfig, zivios, ispcp, plesk, cpanel etc. i wonder what the pros and cons are with these solutions. a lot of people is saying that they are not as good as using pure command line (ssh) to manage your server. but i think thats yet another "linux are for advanced users" talk. i agree that a lot of things may only be done with the command line by editing directly in the configuration files. but i don't really want to do that every time and for everything. especially basic configurations these could manage. its like not having phpmyadmin for managing mysql. it would be a pain in the ass right? so if one wants to throw up a web server serving a php site oneself developed and wants all the usual stuff up and running (mysql, phpmyadmin, svn, webdav etc) is these tools the right way to go? and for more advanced features, one just use the terminal like old days. is this a smart way of managing a linux server? and which one would you choose? have you used any of these and could share your thoughts about them?

• Cisco ASA intermittently fails to see traffic

  - by DrStalker

  users | Mikrotik -- Internet | ASA | ServerA and ServerB I'm trying to troubleshoot a problem with a new Cisco ASA 5505. The network design is as above - the Microtik is the existing router, ServerA and ServerB used to plug directly into it. ServerA has IP 10.30.1.10, ServerB has IP 10.30.1.11 The ASA is configured with no NAT, a "allow anything" firewall, and uses the microtik as its default gateway. In effect, it is currently a simple IP router; the firewall and VPN stuff will all come later once the basics are working. Th problem is access to ServerA and ServerB is erratic - sometimes it will work, sometimes it will fail. It can fail for either one of the servers only, or both. When it is working: The Mikrotik logs show ping packets being sent out over the proper interface The ASA logs show the incoming connections. When it is failing: The Mikrotik logs show ping packets being sent out over the proper interface The ASA logs show nothing reaching the ASA. This can fail for one server only (e.g.: the Mikrotik is putting out packets to 10.30.1.10 and 10.30.1.11, but the ASA is only seeing packets arrive destined for 10.30.1.11) It can fail for one source only (e.g.: ClientA on the users network can ping 10.30.1.11, but clientB cannot) The problem can also be seen from the mikrotik router itself; sometimes it can ping ServerA and ServerB, sometimes it can only ping one of them What could be causing this? I can't think of any possible cause that is intermittent and could explain why the problem may occur for one destination server and not others. edit: Link to ASA config

• How do Opera's keyboard shortcut settings work?

  - by zem

  Firefox 4 beta is starting to freeze up the way Firefox 3 used to on my machine, and I want a browser that'll play gifs at full speed, so on a Mac my only other choice seems to be Opera. There are just two issues I have with it right now: one, the scrolling is weird compared to every other Mac application, but I can get used to that if there's no way to fix it. Two, cmd-1 through cmd-9 activate the "speed dial" bookmarks instead of selecting tabs 1-9, like in Firefox and Chrome. I can disable those shortcuts easily enough, so I don't keep accidentally loading a different page when I instinctively try to do that, but in an ideal world I could remap those commands to do what I want. The keyboard shortcut editor is weird: There seems to be a scrappy little language for associating actions with commands. It has some limited autocompletion when you type stuff in, and I couldn't find a "select specific tab" action, but some of the existing commands are complicated enough that I'd be surprised if there's not a way to do it. Is there documentation for this language anywhere? Clicking "help" just brings me to this page, which is not very helpful.

• Make Thundirbird use and sync with Gmail Spam facility

  - by Senthil

  I am using Thundirbird 3.1.7. I am using Gmail with it. When I mark a message as spam in Thunderbird, I want it to go to Gmail's spam folder. But it is not happening. The mail is only marked as spam and stays in Gmail's inbox. How can I setup Thunderbird so that when I mark a message as spam in thundirbird, it goes to spam folder in both Thunderbird and Gmail? FYI: I have disabled Thunderbird's own adaptive spam controls so that it doesn't interfere. I am perfectly fine with Gmail's spam facility and don't want Thunderbird to add another layer of spam filtering. Still Thunderbird doesn't send emails to Gmail's spam. Update I figured that dragging and dropping the email to the spam folder in Thunderbird does the job. But is it the same as marking the email as spam in Gmail's interface? i.e. Gmail will do stuff when you mark an email as spam so that it can filter out similar messages in the future. Does it happen when I do this drag and drop thing too? Are they the same?
