• capture nimbuzz traffic

  - by lurscher

  I need to capture all the traffic, specially during login, between nimbuzz pc client and nimbuzz server. The reason is that i need to debug outgoing packets at login that mark the user visibility status in order to reproduce them in a in-house XMPP client application I've tried doing this with wireshark, but i seem to be pretty helpless with this tool. Also, the packets i've been able to see are all before the SASL negotiation happens, after that, i cannot see the xml packets being exchanged any help for how to achieve this task is greatly appreciated (preferably on Windows, since there is no nimbuzz client for linux, in any case i can install one in a VM and monitor the traffic between the VM instance in the linux host)

• How can one-handed work in Emacs be eased?

  - by N.N.

  My right hand is temporarily immobilized and I would like to do some minor work in Emacs, mostly in Org-mode, but also in AUCTeX. Are there ways to ease one-handed work in Emacs, such as some mode or particular work flow? For instance I noticed that for undoing it is easier to press C-x u than C-_ and that it is easier to mark text with methods involving C-Space than with combinations of S- and movement commands. I have found http://stackoverflow.com/questions/2391805/how-can-i-remain-productive-with-one-hand-completely-immobilized but that is not exactly what I am asking for. I want to ease whatever little time spent one-handed in Emacs (not in general) and this is also interesting for situations where there is no injury involved, such as when one hand is occupied. I do realize that I should avoid unnecessary strain. I am using GNU Emacs 23.3.1 in Ubuntu 11.04.

• Panic Transmit file upload

  - by 1ndivisible

  I've ditched Coda and bought Transmit. I'm a little confused by the file uploading. I have exactly the same folder structure remotely and locally, but if I right-click a file and choose Upload "SomeFileName.html" The file is always uploaded into the root of the remote site, even if the file is in a folder. If I choose to upload a file at assets/images/some_image.png I would expect it to be uploaded to the same folder on the remote server, not the root. Coda dealt with this perfectly and also told me what files had been modified and needed uploading. Transmit doesn't seem to do either of these things. So my questions are: How can I upload a file to the same path on the remote server without having to drag and drop Is there any way to have Transmit mark edited files or upload only edited files. [There is no tag for Transmit so if someone with more rep could make and add one that would be grand]

• SELinux - Allow multiple services access to same /home/dir

  - by Mike Purcell

  I currently have SELinux enabled and have been able to configure apache to allow access to /home/src/web with a chcon command granting the 'httpd_sys_content_t' type. But now I am trying to serve the rsyslogd.conf file from the same directory, but every time I start rsyslogd I see an entry in my audit log saying that rsyslogd was denied access. My question is, is it possible to grant two applications the ability to access the same directory, while still keeping SELinux enabled? Current perms on /home/src: drwxr-xr-x. src src unconfined_u:object_r:httpd_sys_content_t:s0 src Audit log message: type=AVC msg=audit(1349113476.272:1154): avc: denied { search } for pid=9975 comm="rsyslogd" name="/" dev=dm-2 ino=2 scontext=unconfined_u:system_r:syslogd_t:s0 tcontext=system_u:object_r:home_root_t:s0 tclass=dir type=SYSCALL msg=audit(1349113476.272:1154): arch=c000003e syscall=2 success=no exit=-13 a0=7f9ef0c027f5 a1=0 a2=1b6 a3=0 items=0 ppid=9974 pid=9975 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=30 comm="rsyslogd" exe="/sbin/rsyslogd" subj=unconfined_u:system_r:syslogd_t:s0 key=(null) -- Edit -- Came across this post, which is sort of what I am trying to accomplish. However when I viewed the list of allowed sebool params, the only relating to syslog was: syslogd_disable_trans (SELinux Service Protection), seems like I can maintain the current SELinux 'type' on the /home/src/ dir, but set the bool on syslogd_disable_trans to false. I wonder if there is a better approach?

• Distribute terrabyte files to the public from web server

  - by MarkJ

  Hi We need to set up a website which makes two or three large files publicly available - the files will be 1 or 2 terrabytes each. Although they will be public, in practise I expect only a relatively small number of scientists will want to download them. What is the best way to allow this? I've had a quick talk to a web-hosting provider (rackspace) and they suggested a hybrid solution. An entry-level managed server (we predict fairly low traffic for the website, but we do need to install some custom CGI software). Some cloud storage which hooks into Limelight Networks. This would host the large files, for download by FTP. It sounded OK to me but I know relatively little about server administration. Does it make sense? Thanks in advance, Mark

• Scalable WordPress Host for High-Volume Site?

  - by Jonathan Eunice

  I need recommendations for a scalable web host for a high volume WordPress web site. For my purposes, high-volume might be 100K-500K visitors/hour. Might think towards a 1M/hour burst rate as a "high water mark." I know WP isn't the highest-performing platform out there (ha!), but it's non-negotiable. I can do "the usual optimizations" (e.g. put static files in a CDN, run and follow the advice of performance analyzers like YSlow, etc). But it will still be WordPress, and there will be a dozen or so plugins involved. So, where to host the site? Most "what's the best WordPress host?" discussions seem to focus on lowest-cost. I need the opposite. What are the high-volume, scalable, or clustered WordPress hosts with which you've had great experiences?

• Ubuntu server loses network connection after ADSL2+ modem reset

  - by squashbuff

  I am using an ubuntu 10.04 server (running on a Lenovo Thinkpad notebook) as my webserver. It is performing well in terms of handling the traffic etc. However my internet connection is ADSL2+ (using Thomson TG782T modem-router) and if the modem is reset, then my server loses network connection. The networkmanager icon shows a red exclamation mark showing that is has no connection. But as soon as I click on it and tell it to connect to eth0, the connection is back on. It must be something that networkmanager is failing to do and because of this, the reliability of my webserver is suffering. Any advice on how this can be fixed?

• Formula-based Excel page headers

  - by Jake Krohn

  I'm using the "Rows to repeat at top" function in Excel's "Page Setup" dialog to ensure that a multi-row header block appears on every printed page of my worksheet. However, I'd like to be able to change certain bits of the header based on the content of the current page. I would simply like to display the value of one cell in the first row that is printed on the page. If this is my header: Section: xx And the data looks like this (columns are Section and Name): 1 Foo 1 Bar 2 Baz I want the "xx" in the header to be "1". If, further down on the next page, the value in the Section column is "3", I want that printed in the header of the next page. I originally thought that using the "OFFSET" function might help, e.g. ="Section: "&OFFSET(A2, 1, 0) But it only shows the offset from the original placement of the header, thus only working on page 1. The end document is a PDF, so right now I'm able to go back in with the "TouchUp Text Tool" in Acrobat and add the numbers page by page. But it gets to be a tedious process with 70+ page reports. Anyone have any better ideas that don't require me mucking up the original Excel document with inserted headers every N lines? This is Excel 2008 for Mac, if it makes a difference.

• Splitting Multiple Files in Windows

  - by Justin Boucher

  We have a 21TB LUN full of images that are approx 600K in size in multiple sub folders on the disk. We are trying to split the 21TB LUN into 8 smaller LUNs that are about 2.6TB a piece in order to process the images more effectively. My question is how we can determine what 2.6TB is on the drive? What is the best tool to mark this data so we can copy it to the new smaller LUNs with robocopy or emcopy without overfilling the smaller LUNs? Is there a third-party tool that would be better suited for this task? Thank you in advance for your assistance.

• Ok to edit task's xml file in c:\windows\system32\Tasks?

  - by Eyad

  I wrote a PowerShell script that check the executable in the < action tag for each task in the Task directory and mark the < enabled TRUEorFALSE< / enabled tag as false/true depending on the validity of the digital signature of the executable. After reading each task, the script re-saves the task file with the same name, type and location. Now my issue is that I get this message when I lunch task scheduler: “Task XYZ: The task image is corrupt or has been tampered with.” This message appears for all the tasks that were scanned and saved. Does editing task’s xml file directly corrupt the task? Is there any task decency that may cause this error(ex: registry value)?

• Will Hotmail DELIVER to spam-friendly ISP?

  - by Oddthinking

  I have a user who is using Hotmail to communicate with one of our suppliers. Recently, Hotmail started bouncing emails to that address (while other ISPs are working fine.) Hotmail bounce messages contain very little details. Investigating, I found that the supplier's ISP has appeared on a blacklist of ISPs who do not do enough to prevent spamming from their users. (Note: Neither my user nor the supplier are mass-mailing.) In the circumstances, I can understand Hotmail declining to accept emails from the host, or accepting them but being quick to mark them as spam. However, I am surprised that they might refuse delivery. Does this sound plausible to you, or am I barking up the wrong tree?

• Chef cookbooks marked as executed

  - by Gonzalo Alvarez

  I have setup a Chef server in our network that I use to manage several nodes. These nodes have a chef-client installed executing as a daemon every X minutes. The problem is that every time the client runs, it executes the recipes for all the cookbooks, even those previously executed, so it consumes resources and sometimes it even breaks thinks (with services restarts, for example). I know that I can avoid executing a piece of code or a recipe I create as detailed here: Prevent chef recipe from executing previously executed action? but, would this mean that I should modify any cookbook that I download from the opscode repository. In other words, is it possible to make the chef server (or the clients) to mark the cookbooks as 'executed' as soon as they are executed the first time?

• Input traffic shaping

  - by whitequark

  I know that I can shape output traffic with tc or a similar tool. However, I want to shape the input traffic now—actually, I want to prioritize downloading of files of certain type through a slow lossy connection. I know the reason tc can only shape output traffic: the host itself has no direct control over the amount of input traffic. On the other hand, TCP has some measures built in it which prevent the TCP traffic from overflowing a slow connection. So, can I mangle something in TCP header so that the remote host will think my connection is slower than it thinks? Suppose that I am able to set the corresponding mark on both types of connections with iptables. Is there any way to reduce the input bandwidth of connections of first type, but only if connections of second type are present?

• Getting Excel to handle CRLF's correctly in CSV

  - by Ben Fulton

  I am creating CSV files to be opened in Excel. The rows are separated by CRLF and that's fine, but some of the input data contains CRLF data in it as well. Per the usual standards, I surround them with quotes, but Excel doesn't seem to recognize the CR character and puts a little box with a question mark in it instead. I can strip the CR's out of the CSV file, but it seems like an unnecessary step. Is there an easy way to get Excel to recognize a CRLF inside a row of a CSV file?

• Ubuntu 10.04 network manager issues

  - by Shark

  I was using the default network manager to connect to my wi-fi network, but if the connection is dropped or router restarted the network manager wont reconnect automatically after i guess a couple of tries and just gives a pop-up to connect manually . To avoid this annoyance I installed WICD but though it does try to reconnect to the network after a drop in connection it is unable to resolve the ip address and i am left with an even bigger annoyance . 1. Is there a way to counter either of these issues ? 2. Something like a background process that will check network status periodically and then try to connect to a favored network ?

• How to force 640*480@60Hz screen resolution on xubuntu 12.04

  - by c2h2

  It seems xubuntu won't be able to correctly set resolution at 640*480@60Hz at its Display settings. And I am unable to correctly my super small 6.4 inch Mitsubishi VGA panel via VGA cable. I have tried to hack both X11 conf /etc/X11/Xorg.conf and xfce4 conf, but all the document I can find is outdated. and conf files are changed into other location. Can someone give me a hand and I'll mark correct for other people to use? Thanks! EDIT: The board is an Intel Atom D2700, gpu is SGX545. I tried to use xrandr --output default --mode 640*480 It seems works fine, but refresh rate is 75Hz, but the screen only suports 60Hz So I used xrandr --output default --mode 640*480 --rate 60 but it give error: xrandr: Failed to get size of gamma for output default Can anyone pointing any directions?

• Import data in Excel that doesn't have a row delimiter, but number of columns is known

  - by Alex B

  So i have this text file that looks something like this: Header1 Header2 Header3 Header4 A1 B1 C1 D1 A2 B2 C2 D2 and so on. When imported, I'd want the data to format itself in 4 columns. I tried the Get External Data from Text, and it successfully imports it, but it doesn't wrap it around, so it just keeps making columns for every space. I'd want it to go on the next line after 4 (in this case) elements have been added. What's the simplest way to achieve this? EDIT: My answer follows, since I'm not yet allowed to answer my own questions yet. The Excel function I needed is called indirect(). Not sure how it actually works though, so hopefully someone can help out with that, but the function call that worked for me is =INDIRECT(ADDRESS((ROW(A1)-1)*4+COLUMN(A1),1)) which i found over here: http://www.ozgrid.com/forum/showthread.php?t=101584&p=456031#post456031 Note: this required me to add the text to excel where i'd get this row full of columns, and then flip it so that i'd have a column full of rows.

• After upgrade to Windows 8.1, no Skydrive icon in task bar

  - by Jeremy Butler

  I upgraded to 8.1 and now I don't see the SkyDrive icon in the task bar, nor the green light under it indicating the my computer is communicating with SkyDrive. When I go into Control Panel |..|Notification Area Icons, SkyDrive is listed and noted as Up to date. However even though I mark it to Show Icons and Notifications I don't see any icon in the taskbar. Is it supposed to be this way, or do I have a problem? I kind of got used to that little green synchronizing indicator giving me a warm and fuzzy feeling.

• Backup tape compression

  - by pufferfish

  What things should I check to confirm that compression is actually happening on our tape backup system? Although the tapes are marked as 200G/520G (native/compressed) capacity, they seem to fill up before the 200G mark (some less than 100G). I'm using - Sony AIT-4 tape autochanger - Sony SDX4-200C (AIT-4) tapes - Ubuntu Lucid - Bacula I've tried checking hardware compression with: tapeinfo -f /dev/nst0, which gives Product Type: Tape Drive Vendor ID: 'SONY ' Product ID: 'SDX-900V ' Revision: '0102' Attached Changer API: No SerialNumber: '0001000036' MinBlock: 2 MaxBlock: 8388608 SCSI ID: 1 SCSI LUN: 0 Ready: yes BufferedMode: yes Medium Type: Not Loaded Density Code: 0x33 BlockSize: 0 DataCompEnabled: yes DataCompCapable: yes DataDeCompEnabled: yes CompType: 0x3 DeCompType: 0x3 BOP: yes Block Position: 0 Partition 0 Remaining Kbytes: 201778000 Partition 0 Size in Kbytes: 201779000 ActivePartition: 0 EarlyWarningSize: 0 NumPartitions: 0 MaxPartitions: 0 ... so I presume it's on.

• Stupid question: prevent file from being changed under linux

  - by Josh

  Ok. Stupid question. I have forgotten what this is called and without remembering the name the search function on the site and on google is failing me. What's the command under linux to mark a file as "locked"/to prevent any changes from being made to it? I'm not talking about chmod. There's a property that can be set (again the name escapes me at the moment) which prevents even processes running as root from changing a file. What is this called and how do I set it?

• Is there an easier way to type apostrophes on the Droid X keyboard? [migrated]

  - by Deane

  Is there an easier way to type apostrophes on the Droid X keyboard? I press and hold the period key, which brings up the little pallet of punctuation. But the apostrophe is inexplicably all the way over on the left. Can I move this closer to the right, where my thumb is while clicking and holding the period key? Alternately, can I somehow get an apostrophe on the overhead menu that appears when you type a space? This is the place where auto-correct goes, but when you type a space, it becomes a comma, exclamation point, question mark, etc. How can I get an apostrophe in this list?

• Recommend a web file sharing software please.

  - by Baczek

  I'm looking for a web platform to put company files at. My requirements are: should be accessible via a browser should be open source must be installable (dropbox is a no-go) must have an option to put a access time limit on a file must perform garbage collection automatically after a file expires must be able to mark files as public or private an option to protect a file via a pin-code for users without accounts in the system would be nice to have The problem is I don't even know what to search for - all my googling results in either complete groupware solutions or p2p file sharing software. If such a thing doesn't exist, please don't hestitate to say so, so I can crawl to a corner and cry myself to sleep. TIA
