[SOLVED] Subversion, xinetd, and "Malformed network data"

Hi,
I currently have a Subversion 1.5.2 server running through svnserve + xinetd. When I attempt to connect to my subversion server, however, I get:
svn: Malformed network data
Below is the contents of my xinetd config for subversion:
service svn
flags = REUSE
socket_type = stream
wait = no
user = svn
group = svn_group
server = /usr/bin/svnserve
server_args = -i -r /srv/svn/repo
log_on_failure += USERID
disable = no
This is located in the file: /etc/xinetd.d/svn
I run the following command only to find that it fails:
$ svn ls svn://localhost/myrepository
svn: Malformed network data
I've checked my xinetd log, however I see no failure. I can even put a completely bogus repository URL into SVN and it'll still give the same error:
$ svn ls svn://localhost/iosudohslkj2223oijosdijfaksjdlfkj
svn: Malformed network data
Anyone have any idea what could be causing this?

I found out via telnet that one of my directories didn't have execute permission, so it couldn't step into the child directories.

[Solved] Still learning and stuck with 'date'

Hi there, I thought it was about time I learned the fine art of shell scripting, but as the title states, I'm stuck.
A file with some text, one of which is this:
Download time: September 8 12:17:37
This I need to grap and convert to a computer readable format, so that I may compare it with another.
This shouldn't be too hard:
cat ~/unitinfo.txt | grep 'Download time: ' | cut -c16- | xargs date +"%B %-d %T" -d
But, when I execute this above, I get the error:
date: extra operand '8'
I've tried various variations, but nothing seems to make a difference, all thought the format is a perfect match when I get 'date' to print it.
Please advice and best regards.

Just for the fun of it, if you care to comment on my progress so far:
unitinfo.txt:
Current Work Unit
Name: Gromacs
Tag: -
Download time: September 8 12:17:37
Due time: September 12 12:17:37
Progress: 25% [||________]
fah.sh:
#!/bin/bash
dueTime="$(date +%s -d "$(grep 'Due time: ' ~/unitinfo.txt | cut -c11-)")"
downloadTime="$(date +%s -d "$(grep 'Download time: ' ~/unitinfo.txt | cut -c16-)")"
currentTime="$(date +%s)"
progress="$(grep 'Progress: ' ~/unitinfo.txt | cut -c11-c12 | sed 's/ *$//')"
Now that I look at it again, am I correct that
sed 's/ *$//'
might as well be
sed 's/ $//'
In any case, there a long way to go.

Apple TV3 setup reports that: "iTunes login failed - cannot sign-in until Network date and time has been set".

During Apple TV setup, I have not been able to complete the Home Sharing process. Computer/iTunes Home Sharing is setup, but ATV "blocks" its Home Sharing setup. After my Apple ID and password is entered, ATV reports a failure. Also, attempts to login to iTunes from ATV, ATV reports: "iTunes login failed - cannot sign-in until Network date and time has been set". It directs me to the Network tab, but there's no option to set date and time. I have no clue how to do that.
Help!!! Thanks in advance to anyone who knows how to solve this.

Welcome to the Apple Community.
There are things to look out for to make sure your Apple TV can reach the network time server, such as ensuring port 123 is open and only using the DNS address provided by your ISP, but since it was OK one moment and not the next, my guess is these settings are already correct.
As for the restart, did you try restarting by removing ALL the cables for 30 seconds.

Network based and a-gps, data use tests

i was trying to find this kind of info, but only found others asking.
i hope this is useful info for others, especially while roaming.
skip to the bottom for conclusion,
this is the process i took:
i called nokia tech support,
their phone support his horrible,
the people on the phone don't actually know anything, and have to look up everything you ask them.
they were the worst.
i emailed nokia tech support.
my message was:
"i would like to know the difference between assisted gps positioning, and network based positioning. these are 2 of the 4 options on my nokia e66 for positioning methods. i would like to know if network based positioning uses internet data from my service provider to obtain my gps position. i am especially concerned with this function while i'm roaming internationally, as i do not want to be charged for roaming data use."
in about half hour they responded w/ an answer, and then 45 min after that someone else responded w/ an answer.
the first response, minus the hello's etc. was:
"In response to your email, Assisted GPS and Network Based positioning methods generate costs related to data traffic so you will be charged for data use. Only "normal" GPS and Bluetooth GPS do not generate additional costs related to data traffic.
Normal GPS is quite slow and does not work indoors. Therefore, it is recommended to enable at least A-GPS to get a faster position outdoors.
Network based and Wi-Fi positioning also allow you to update your position inside buildings, but they cannot be used for navigation."
the 2nd response was:
"In response to your inquiry, the difference between Assisted GPS positioning (A-GPS) and Network based positioning is that, A-GPS uses satellites while Network based positioning is based on information of your cellular network environment. It allows you to update your position inside buildings, but they cannot be used for navigation. Both positioning methods generate costs related to data traffic (unless you have configured the device to use Wi-Fi connection to make the internet connection). The cost may vary while you are on roaming. Kindly contact the service provider for information about data transmission costs."
i can also respond w/ more questions, but instead did some tests, starting with sitting home, indoors, and eventualy moving to a window w/ lots of sky.
test 1:
i enabled:
integrated gps
network based
assisted gps
opened maps,
set maps to be offline,
set default internet access point to my home wlan network,
closed maps,
cleared all counters and the log on the phone's communication log.
opened maps
there is a pink circle around the area i may be in,
the icon that would show gps satellite strength, changes to show the cell phone antenna icon.
but the packet data counter is sending/receiving a total of around 3-8kb immediately, and over the course of time, it keeps adding up, every 1-2 minutes, and it is shown as packet data to/from the access point "at&t internet"
over the course of ten minutes, it's been about 43kb.
and i can tell on the phone's home screen that the packet data connection becomes active when it does.
the maps kb indicator still says 0.0kb, with a line through the double arrow packet data symbol.
test 2:
now i exited maps,
cleared the counters and logs
i turned off a-gps.
enabled only integrated gps and network based.
i open maps,
the same thing is happening as with the assisted gps on, except i connected to my home wlan once, in the middle of connecting to at&t internet 10 or so times.
everything else is happening the same.
test 3:
i exited maps,
cleared the counters and logs.
enabled only integrated gps.
i open maps, and there is no evidence of packet data connection, or wlan connection.
nothing is showing up in the logs or packet counters, and there is no pink circle around where i may be.
if i set maps to go online, w/ my wlan as the access point, or at&t internet, their respective icons show up on maps, as well as the phone's home screen.
the phone's log show respective connections are made but w/ 0.0kb, and the phone's packet counter, as well as the maps kb usage, say 0.0kb.
test 4:
set maps to offline, w/ my wlan as access point.
exited maps,
turned phone off for a bit to test gps from cold start.
turned on phone,
cleared counters/logs,
enabled only assisted gps and integrated gps.
open maps, there's no pink circle around where i may be, just the red dot of where it thought i last was.
there's about 4-5kb of data transfer,
then i bring the phone to the window where there's a lot of clear sky, and my location is found pretty fast.
i know that w/o assisted gps, w/ only integrated gps, it takes a while to get the gps signals.
i went back and forth to/from the window, and there was packet data use again only once more, not continuously like w/ network based positioning.
so to conclude my tests,
setting the maps to be offline, still uses a-gps and network based positioning.
network based uses a more data, continuously,
which is the opposite of what i thought, i thought a-gps would use more, so i was using network based on and a-gps off while in canada. whoops.
using assisted gps uses about 5-10kb, which, when roaming, according to at&t, they charge 1.95cents/kb.
might be worthwhile for getting a quick gps signal, nothing worse than waiting forever for it to connect.
the only way to be completely clear of data use is disable network based and assisted gps, or set the phone to offline mode.

A-GPS: This uses information from cell network to get a rough idea of where you are. It then uses this information to figure out which satellites to look for. Result is a faster satellite lock. So A-GPS uses a few kB of data to get an initial position, but navigation is done using GPS satellites, which does not require ANY data connection.
Network based: This uses information from the cell network to plot the current position when GPS satellite signal is not available, ie indoors, in a tunnel, etc. Position info derived from the cell network is not as accurate as that from GPS satellites, but serves as a stopgap until GPS signal can be re-acquired. Network based positioning used your data connection EACH TIME the satellite lock is lost. So the amount of data used is dependent on the quality of access you have to the GPS satellites. If you don't lose the connection to the GPS satellites, then you won't use any data.
The ‘offline’ option within the Nokia Maps app only refers to street, POI, etc searches, NOT to A-GPS, Network based positioning or to connecting with the GPS satellites.
If you want to navigate without using ANY data connection, set A-GPS off AND set Network based positioning off AND set the Internet option in Nokia Maps to Offline. Do this and you will not use any of your data connection allowance when navigating. There is no need to put the phone into flight mode.
If I've helped you, you can thank me by clicking the green 'kudos' star on my post. Cheers.

How to solve delay in a program with data aquisition and processing

Hello, I am a starter in Labview programing. I am working on a system which contains a roller, a piston and a A/D cart which is from Data Translation Inc (DT304). I am using labview to get speed data of the roller (which is voltage first then be converted into speed) from Analog Input Channels, and then using Analog Output Channels to control the friction force being appylied to the roller by using a piston.
I am using a Waveform Chart to show the speed of roller. However, as I am adding more components to the program, I always get delay in the speed display and also the output control of the piston. Also, as I spent more time using the program eg. from morning to night, it became slower too.
My question is, how does labview store data and how are the data been stored and released in the buffer.Is it because I am loading too much data in the buffer so that it became slower? And also how to solve these delays?
I am using the "save to file" function to write data to a ".lvm" file, but I did some changes to the saving by using a button to enable and disable saving. So I don't think the problem is because I am always saving the data into a file.
Thank you very much.
Jessie

I'm betting it's two things:
1. Program Architecture
and 2. Dynamically resizing arrays.
With the program architecture... if you have one do-while loop that acquires data from teh DAQ, processes it, opens/indexes/writes/closes a file, then comes back around... as your arrays and files increase in size, the loop is going to take longer to execute. A Producer-Consumer loop (a good tutorial on them can be found here) has one loop that acquires data and stuffs the data into a queue. This will buffer the data while it's in transition between acquisition and processing. A second loop in parallel takes data in from the queue, processes it, then comes back around. The two loops operate independently of each other, so even if the consumer loop takes longer as the files or math gets more complex, the producer loop continues to run full speed.
Second is the arrays. Every time you append data into an array, LabVIEW has to make a copy of the data that's in the array. If you append small amounts of data to an array over and over and over again, eventually LabVIEW is going to be copying very large amounts of data over and over and over again. The producer-consumer architecture can alleviate this problem.

Xfce4 and gnome-network-manager [solved]

I just made a clean install of archlinux. installed xorg and Xfce4, xfce-goodies, gnome-panel, gnome-desktop and gnome-network-manager. also I enabled GNOME services in startup and sessions. how do I start that network manager now? is nowhere in the settings, nor there is icon to add to the taskbar (i got xfapplets installed too)

quoted from a previous thread
I solved it by uncommenting my <locale><charset> in /etc/locale.gen.
First you have to enable the locales you want being supported by your system. To enable or disable them, the file /etc/locale.gen is used. It contains every locale you can enable, and you have just to uncomment lines you want to do so.
As we want to setup an english UTF-8 conform system, we want to enable en_US.UTF-8. But for compatibility to programs that don't support UTF-8 yet, it's recommended to support any other locale, prefixed with en_US as well. Having this in mind, we enable this set of locales:
en_US.UTF8 UTF-8
en_US ISO-8859-1
After you've enabled the necessary locales, you have to run locale-gen as root to update them:
# sudo locale-gen
Generating locales...
en_US.UTF-8... done
en_US.ISO-8859-1... done
Generation complete.

Can I use GPS while the data and cellular networks are turned off?

Here's the deal: I am traveling on the Alaska Highway from Alaska, through Canada, to the lower 48 states. AT&T has advised me that while I am in Canada I will be charged 79 cents a minute for airtime and 2 cents per kilobyte for data. Ouch. Given this, I intend to turn my iPhone on "airplane mode" while in Canada, so I don't accidently fetch mail, or do some other thing which would load data at the cost of 2 cents per KB.
BUT! I would like to be able to take pictures with my iPhone 3G and have them tagged with location by the GPS. Everything I have read indicates that GPS is turned off when the phone is in Airplane Mode.
So, my question is: can I still retain access to GPS for my photos while turning off all other radios in my phone? With the new Places feature in iPhoto, I'd really hate to have 2,000 miles worth of photos and no location data to go with them, ya know?

Tamara, thank you. Of course I already did that, and no, they are not geotagged. Which is why I specifically phrased my question, "can I still retain access to GPS for my photos while turning off all other radios in my phone?"
In other words, is there SOME WAY--ANY WAY--to turn GPS back on, like you can with Wi-Fi? Or maybe there is some way, any way, to turn off all the cellular functions only, while leaving the GPS receiver on?
I am aware of the "Data Roaming" setting in the Network settings. I have always had that turned off, but I cannot experiment with that setting, as I am not in an area where roaming would occur.
I'm just hoping to avoid a surprise huge bill due to GPS grabbing some data or relying somehow on the cellular network, and am hoping to know if anyone has any experience with these issues. At 2 cents per KB, an average email would cost $1 to download. I have no idea what kind of data flies back and forth when GPS is used, or if the ONLY data received by GPS is from the navsat system. I seem to recall that iPhone GPS also relied somewhat on cellular data, though for photo geotagging it probably shouldn't have to.
I apologize if I was not clear in my questions.
Thanks so much for your help!

ColdFusion and Connect:Direct (a.k.a NDM - Network Data Mover)

Hi All,
Our client is looking for an alternate for FTP and it seems they might go for IBM's Connect:Direct (previously known as NDM - Network Data Mover).
Can anyone share the feasibility of accomodating this Connect:Direct software as an replacement for current FTP activities?.
Thanks in advance!

I don't think you've given enough information for people to give you useful responses. Are you asking about how CF interacts with this product? (Answer: it doesn't directly, you'd have to use CFEXECUTE.) Are you asking about using this to replace FTP server functionality on your server? Is this for public or internal use? Etc, etc.

[SOLVED] KVM and Bridged Networking

I've got KVM working and a Windows 2008 server installed on a image now, but it's only getting a NAT ip address. I need to get this server onto my main network, on Windows I'd use Virtual Box and Bridged Networking, but I thought I'd give KVM a try out.
I've followed the setup at https://wiki.archlinux.org/index.php/KV … Networking
Using Netcfg
Bridged networking is used when you want your VM to be on the same network as your host machine. This will allow it to get a static or DHCP IP address on your network, and then you can access it using that IP address from anywhere on your LAN. The preferred method for setting up bridged networking for KVM is to use the netcfg package. You will also need to install bridge-utils.
Netcfg#Configuring_a_bridge_for_use_with_virtual_machines_.28VMs.29
And this page https://wiki.archlinux.org/index.php/Ne … _.28VMs.29
I've got a bridge working I believe (all my stuff is DHCP by the way)

I've got "bridge" added to my rc.conf as a MODULE which is loaded. (I saw reference to this somewhere else on the forum that this might be needed)
I'm starting my VM with the following command
qemu-kvm -vnc 192.168.1.52:0 -hda Nekomi -m 2048 -smp 2 -net nic
Yet I still can't get an IP outside of the 10.0.0.0 range on the VM.
The VNC line above is because the HOST has not VGA output at all, completely headless.
I'm trying to get this working and trying to learn at the same time. KVM is new to me, as is bridged networking on linux.
Any ideas? Thanks

Sorry for the delay, bit a PC rebuild occurred :-(
Anyway, I managed to get this working with steps #1-#7 from the linked section. Thanks for that. I did have a few minor issues in getting a DHCP on the host machine itself, turns out I'd missed a single ) from the daemons section of rc.conf. A human error, but difficult to fix as the machine was rendered off the network and without a VGA card... fun!
I diverge, I have this script to bring up a bridge when the qemu-kvm starts
#!/bin/sh
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2
But when the kvm shutdowns it complains it can't find qemu-ifdown script. So I'm thinking of making one but just want to check it over first.
#!/bin/sh
echo "Executing /etc/qemu-ifdown"
echo "Removing $1 from br0..."
sudo /usr/sbin/brctl delif br0 $1
echo "Taking down $1 from bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc down
sleep 2
I've reversed the logic here, is the above the correct way to bring down the guest interface?

Most horrible and worst network - 100MB data for life

I responded to the EE advert in December on buy a new smartphone on PAYG and get 100MB data every month. Having fulfilled my part, the first 100MB started in January. After transferring my old number the 100MB got lost. Since then, its been stories upon stories. Last month I was told on four consecutive times in two days that 100MB was added to my phone and before I could switch off and on to start using it, the 100MB was used up. Very absurd. Later customer services apologised and I was given 1GB. This month the same story has started again. I called and spoke to one Sarah on 29th and she told me I needed to make £5 top up to get the 100MB data to work. I checked the terms after the call and realised it was a lie. I called back to complain only to be told by the next person that the 100MB data is used up. I was promised calls back and that didn't happen. Yesterday I was promised a call back today and then about 1 hr later I see a missed call from EE and the person has put a note on my account that she tried calling and didn't get me meanwhile I was told to expect the call today. EE to me has been synonymous with lies expecially their customer service.

Did you get anywhere with this? I'm having a similar issue and they're flat out denying the offer ever existed and even hanging up on me.
Wish I could just stay on the line with the first English person I get, the foreign callcentre is just a mess.

[SOLVED]MSI P31 Neo -mobo and strange network problems

I can't get network to work properly with this MSI-mobo's integrated lan chip.
When I boot from Arch install cd r8169-module is loaded and I can get ip via dhcp. Strange thing is that I can access http but not ftp. When I change transfermode to passive from links ftp works. But during Arch install setup I can't access the repos.
When I boot to Arch after install network doesn't work at all. Only thing I get is resolv-errors when I try to use wget or pacman. R8169 module is loaded at boot and Ifconfig shows that I have ip assigned to eth0.
I also tried with 3com's 3c509 network card that I had laying around and I have exactly same network problems with it as I have with r8169.
I am really going out of my mind with this. I have a laptop with via's network chip and I've never had any network problems with it and Arch. I haven't changed anything in my routers setup and I just tried and the networking on my laptop works just fine.
I also tried Ubuntu Hardy on this desktop machine and networking works ok. Ubuntu also loads the r8169 module as Arch does.

UPDATE:
I tried booting with 2 RAM Chips and it works great! This seemed to be the problem.
The ram IS double sided which would explain it.
If you are wanting some more system specs, just ask and I will try and get the most I can.
Del UK:
If I could run 4gb it would be great but I cannot seem to find the SPD in bios. My BIOS is American Megatrends Inc. v02.61 so it would be great if you could help me with that!
If all else fails I might either just settle with 2GB or buy some new RAM chips. Can anyone please tell me some Ram chips which would be able to give this mobo 4GB?

BB 9330 - turning off mobile network data services causes BIS WiFi connection to change to not connected

re: v. 6.0.0.719 bundle 3084 platform 4.4.0.560 update
1. History.
a. Received BlackBerry Curve 9330 out of the box with bundle 2333 installed (but missing Verizon Visual Mail Message app.) Installed BB Desktop Software on laptop, connected smartphone to PC, Attempted to install bundle 3084, but initialization apparently failed, phone still showing bundle 2333 installed and no VVM app. Browser app unable to connect to network. On second try was able to complete 3084 install. Still no VVM app. Now some times the browser connects, sometimes it does not. Browser not connecting appears to be BB software bug. VVM issue appears to be one for the service provider.
b. Data service is currently Verizon BlackBerry Social Messaging Data Package which is suppose to have BlackBerry Internet Services via WiFi per Verizon FAQ doc.
2. Problem. With an active WiFi connection the Browser app is not connecting via WiFi giving a error message that WiFi service is required.
Investigation found if mobile network data service was turn off in Mobile Network Options, the BlackBerry Internet Services connection status was changed from connected to "WiFi" to "not connected". Browser appears to work ok when mobile network data service is turned on. BIS connection to WiFi comes back on. Not sure at this point if web data is going via mobile network or WiFi.
I am wondering if other BB 9330 Verizon users are seeing the same symptoms.
Bill
P.S. I could not find where to report this apparent software bug. So I hope is the right place.

If you have your Mobile Network as well as Wi-Fi turned on, your phone will default to the Wi-Fi for browsing (assuming you have a strong Wi-Fi signal). Leaving both on will allow you to browse as well as receive calls and texts.
I hope that helps you.

FMS 3.5 says 'Bad network data': error in handling RTMP extended timestamps / chunkSize?

Hello all,
For a client, I am working on a project where a live RTMP stream is published to an Adobe FMS 3.5.6 server from a java application, using Red5 0.9.1 RTMPClient code.
This works fine, until the timestamp becomes higher than 0xFFFFFF after 4.6 hours, and the RTMP extended timestamp field starts being used. I have already found: when the extended timestamp was written after the header, the last 4 bytes of the data were being cut off. I have fixed this locally, and now the data being sent seems to me to be conformant to the spec. However, FMS still throws an error message in the core log and then kills the connection from the Red5 client. Here is the error message:

The message for which the hex dump is displayed, is a video message of size 4925 bytes. Below is the basic logging in my application:

I have captured the entire frame containing this message with wireshark, and annotated it a bit. You can find it here:

The video message of 4925 bytes (hex 00 13 3D) is cut up into chunks of 1024 bytes (chunkSize 1024 set by Red5 client and sent to FMS). Indeed, after the 12-byte header and the 4-byte extended timestamp, there are 1024 bytes before the 1-byte header for the next chunk (hex C5). The chunks after that also contain 1024 bytes after the chunk header. This appears correct to me (though please correct me if I'm wrong).
When we look at the error message in the core log, the hex dump displayed also contains 1024 bytes, but it starts from the beginning of the message header. The last 16 bytes of the message chunk itself are not shown.
My question is this: is the hex dump in the error message always capped to 1024 bytes, or did FMS really read too little data?
Something that may be of help, is the reported 'too long' message length 11893407. This corresponds to hex B5 7A 9F, which can also be found in the packet, namely at row 0c60 (I've annotated it as [b5 7a 9f]. This location is exactly 16 bytes after the start of the 4th chunk data, not really a place to look for timestamps.
My assumptions during this bug hunting session were the following (would be nice if someone could validate these for me):
- message length, as specified in the RTMP 12 and 8-bit headers, defines the total number of data bytes for the message, NOT including the header of the first message chunk, its extended timestamp field, or the 1-byte headers for subsequent chunks. The behaviour is the same whether or not the message has an extended timestamp.
- chunk size, as set by the chunkSize message, defines the total number of data bytes for the chunk, not incuding the header or extended timestamp field. The behaviour is the same whether or not the message has an extended timestamp.
I believe I've chased this problem as far as I can without having access to the FMS 3.5 code, or at least being able to crank up the debug logging to the per-message level. I realize it's a pretty detailed issue and a long shot, but being able to publish a stream continuously 24/7 is critical for the project.
I would be very grateful if someone could have a look at this hex dump to see if the message itself is correct, and if so, to have a look at how FMS3.5.6 handles this.
Don't hesitate to ask me for more info if it can help.
Thanks in advance

Hello,
It took a bit longer than expected, but I have managed to create a minimal test application that will reproduce the error condition on all machines I've tested on. The application will simply read an H264 file and publish it to an FMS as a live stream. To hit the error condition faster, without having to wait 4.6 hours, the application will add a fixed offset to all timestamps before sending it to the FMS.
I have created two files:
http://www.solidity.be/publishtest.jar : Runnable java archive with all libraries built in
http://www.solidity.be/publishtest.zip : Zip file containing sources and libraries
You can run the jar as follows:
java -jar publishtest.jar <inputFile> <server> <port> <application> <stream> <timestampOffset>
- inputFile: path to an H264 input video file
- server: hostname or IP of FMS server to publish to
- port: port number to publish to (1935)
- application: application to publish to (live)
- stream: stream to publish to (output)
- timestampOffset: nr of milliseconds to add to the timestamp of each event, in hexadecimal format. Putting FFFFFF here will cause the server to reject the connection immediately, while FFFF00 or FFF000 will allow the publishing to run for awhile before the FMS kills it
Example of a complete command line:
java -jar publishtest.jar /home/myuser/Desktop/movie.mp4 localhost 1935 live output FFF000
Good luck with the bug hunting. Let me know if there is anything I can help you with.
Kind regards,
Davy Herben
