• Ubuntu cannot access internet, LAN is fine

  - by Kevin Southworth

  I have an Ubuntu 8.04 LTS server that is directly connected to our Comcast Business Gateway modem and I have configured it with 1 of our 5 allotted Static IPs. My other machines on our LAN can connect to this server (via ssh, web, ping, etc.) but I cannot access this server from outside our network, and this machine cannot get out to the internet either (ping google.com fails with unknown host). Here is my /etc/networking/interfaces file: auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 173.162.54.19 netmask 255.255.255.248 broadcast 173.162.54.23 gateway 173.162.54.22 and my /etc/resolv.conf: nameserver 68.87.77.130 nameserver 68.87.72.130 output from sudo route -n: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 173.162.54.16 0.0.0.0 255.255.255.248 U 0 0 0 eth0 0.0.0.0 173.162.54.22 0.0.0.0 UG 100 0 0 eth0 I have a Windows 2008 machine with an almost identical Static IP, static DNS setup and it works correctly, can access it within the LAN and also from public internet, the Windows machine and the Ubuntu machine are both directly connected to the Comcast Business Gateway. I have tried rebooting Ubuntu, rebooting my Comcast modem, but nothing seems to make it work. I'm an Ubuntu noob, is there some other config I need to apply to make this work?

• Web browsing is fast, but downloads are slow

  - by Ricket

  I work for a company on my university's campus, helping with general IT problems and some web development. But lately there has been a problem that has me and my boss completely stumped. We, plus one contractor, make up the entire IT department, so I'm reaching out to you for help. All around the office, we have wall jacks. These collect in a closet down the hall and all plug into a switch. This switch, along with our individual server jacks, plugs into another switch, and that switch plugs into our firewall hardware. Then the firewall is connected out to our campus network. Our campus internet is, well, very fast. I don't know exactly the terms, tiers, etc., but we have thousands of students and downloads can run as fast as 10 MB/s at night; uploads are sometimes even faster. I think we're practically ISP level. In short, I have a lot of faith that it is not the campus side of things that is causing a problem, combined with other evidence I'll mention in a moment. So our symptoms: web browsing is fast. Web pages, images, etc. load instantly. No problems there. But then when I go to download something, the download starts fast but very quickly (a matter of seconds) drops to nearly 0. Often it will actually drop to 0 and time out. This happens with even very small files, 1 MB or less. It smells to me like a QoS sort of thing. I'm not entirely sure, and I wanted to get your opinions first. My boss is hesitant to touch our firewall, much less let me touch it, and it was set up and is managed by a consultant remotely. These problems don't seem tied to a time of the day. I've tried downloads after 5:00 and still the same thing happens. From my desk, I can turn on my wireless adapter and pick up the campus wireless access point. If I unplug ethernet and connect to it, downloads are fast. This adds to my suspicion that it's limited to our company network. Also, a number of weeks ago the consultant upgraded our firewall firmware. Suddenly everything was very fast. I tested with downloads from Sun and speedtest.net and things were blazing fast, as they should be with our campus internet! It was wonderful, and I figured the slow speeds were an old firmware bug. In a matter of days, things steadily declined until they were back to the old symptoms. Oh, and we have antivirus installed on every computer, and we keep it up to date. Though I suppose the possibility is still there that someone could have spyware which is bogging down our internet, in which case what is the easiest/best way to find this out? (maybe this should go in a separate question) Thank you for your patience in reading all of this. Do you have any ideas as to what I can try? Is this something that you've experienced before? What sort of tools or methods can I use to try and diagnose the problem? P.S. everything here is Windows. Windows Server 2003 and 2008 on our servers, and Windows XP on employees' machines. Update: We are submitting a ticket to the university to just take a look and see if they see anything unusual and/or can suggestion methods for us to try and pinpoint our problem. Hopefully they'll be helpful! I'll update this to let you know what goes on. Update again: We found a hub (yes, a HUB) right between our campus connection and our firewall. It had only those two ethernet cables plugged into it, nothing else. After removing the hub, our speeds have jumped up to several mbps. However in talking with the campus, we got them to run a gigabit line to our firewall in place of the 100mbps line. As of friday, we are at about 65 mbps up and down (according to speedtest.net at 8am)!! Go NC State!!

• Data Source Connection Pool Sizing

  - by Steve Felts

  Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} One of the most time-consuming procedures of a database application is establishing a connection. The connection pooling of the data source can be used to minimize this overhead.  That argues for using the data source instead of accessing the database driver directly. Configuring the size of the pool in the data source is somewhere between an art and science – this article will try to move it closer to science.  From the beginning, WLS data source has had an initial capacity and a maximum capacity configuration values.  When the system starts up and when it shrinks, initial capacity is used.  The pool can grow to maximum capacity.  Customers found that they might want to set the initial capacity to 0 (more on that later) but didn’t want the pool to shrink to 0.  In WLS 10.3.6, we added minimum capacity to specify the lower limit to which a pool will shrink.  If minimum capacity is not set, it defaults to the initial capacity for upward compatibility.   We also did some work on the shrinking in release 10.3.4 to reduce thrashing; the algorithm that used to shrink to the maximum of the currently used connections or the initial capacity (basically the unused connections were all released) was changed to shrink by half of the unused connections. The simple approach to sizing the pool is to set the initial/minimum capacity to the maximum capacity.  Doing this creates all connections at startup, avoiding creating connections on demand and the pool is stable.  However, there are a number of reasons not to take this simple approach. When WLS is booted, the deployment of the data source includes synchronously creating the connections.  The more connections that are configured in initial capacity, the longer the boot time for WLS (there have been several projects for parallel boot in WLS but none that are available).  Related to creating a lot of connections at boot time is the problem of logon storms (the database gets too much work at one time).   WLS has a solution for that by setting the login delay seconds on the pool but that also increases the boot time. There are a number of cases where it is desirable to set the initial capacity to 0.  By doing that, the overhead of creating connections is deferred out of the boot and the database doesn’t need to be available.  An application may not want WLS to automatically connect to the database until it is actually needed, such as for some code/warm failover configurations. There are a number of cases where minimum capacity should be less than maximum capacity.  Connections are generally expensive to keep around.  They cause state to be kept on both the client and the server, and the state on the backend may be heavy (for example, a process).  Depending on the vendor, connection usage may cost money.  If work load is not constant, then database connections can be freed up by shrinking the pool when connections are not in use.  When using Active GridLink, connections can be created as needed according to runtime load balancing (RLB) percentages instead of by connection load balancing (CLB) during data source deployment. Shrinking is an effective technique for clearing the pool when connections are not in use.  In addition to the obvious reason that there times where the workload is lighter,  there are some configurations where the database and/or firewall conspire to make long-unused or too-old connections no longer viable.  There are also some data source features where the connection has state and cannot be used again unless the state matches the request.  Examples of this are identity based pooling where the connection has a particular owner and XA affinity where the connection is associated with a particular RAC node.  At this point, WLS does not re-purpose (discard/replace) connections and shrinking is a way to get rid of the unused existing connection and get a new one with the correct state when needed. So far, the discussion has focused on the relationship of initial, minimum, and maximum capacity.  Computing the maximum size requires some knowledge about the application and the current number of simultaneously active users, web sessions, batch programs, or whatever access patterns are common.  The applications should be written to only reserve and close connections as needed but multiple statements, if needed, should be done in one reservation (don’t get/close more often than necessary).  This means that the size of the pool is likely to be significantly smaller then the number of users.   If possible, you can pick a size and see how it performs under simulated or real load.  There is a high-water mark statistic (ActiveConnectionsHighCount) that tracks the maximum connections concurrently used.  In general, you want the size to be big enough so that you never run out of connections but no bigger.   It will need to deal with spikes in usage, which is where shrinking after the spike is important.  Of course, the database capacity also has a big influence on the decision since it’s important not to overload the database machine.  Planning also needs to happen if you are running in a Multi-Data Source or Active GridLink configuration and expect that the remaining nodes will take over the connections when one of the nodes in the cluster goes down.  For XA affinity, additional headroom is also recommended.  In summary, setting initial and maximum capacity to be the same may be simple but there are many other factors that may be important in making the decision about sizing.

• OS8- AK8- The bad news...

  - by Steve Tunstall

  Ok I told you I would give you the bad news of AK8 to go along with all the cool new stuff, so here it is. It's not that bad, really, just things you need to be aware of. First, the 2013.1 code is being called OS8, AK8 and 2013.1 by different people. I mean different people INSIDE Oracle!! It was supposed to be easy, but it never is. So for the rest of this blog entry, I'm calling it AK8. AK8 is not compatible with the 7x10 series. Ever. The 7x10 series is not supported with AK8, and if you try to upgrade one, it will fail at the healthcheck. All 7x20 series, all of them regardless of age, are supported with AK8. Drive trays. Let's talk about drive trays and SAS cards. The older drive trays for the 7x20 series were called the "Riverwalk 2" or "DS2" trays. They were technically the "J4410" series JBODs that Sun used to sell a la carte before we stopped selling JBODs. Don't get me started on that, it still makes me mad. We used these for many years, and you can still buy them right now until December 15th, 2013, when they will no longer be sold. The DS2 tray only came as a 4u, 24 drive shelf. It held 3.5" drives, and you had a choice of 2TB, 3TB, 300GB or 600GB drives. The SAS HBA in the 7x20 series was called a "Thebe" card, with a part # of 7105394. The 7420, for example, came standard with two of these "Thebe" cards for connecting to the disk trays. Two Thebe cards could handle up to 12 trays, so one would add two more cards to go to 24 trays, or have up to six Thebe cards to handle 36 trays. This card was for external SAS only. It did not connect to the internal OS drives or the Readzillas, both of which used the internal SCSI controller of the server. These Riverwalk 2 trays ARE supported with AK8. You can upgrade your older 7420 or 7320, no problem, as-is. The much older Riverwalk 1 trays or J4400 trays are NOT supported by AK8. However, they were only used by the 7x10 series, and we already said that the 7x10 series was not supported. Here's where it gets tricky. Since last January, we have been selling the new style disk trays. We call them the "DE2-24P" and the "DE2-24C" trays. The "C" tray is for capacity drives, which are 3.5" 3TB or 4TB drives. The "P" trays are for performance drives, which are 2.5" 300GB and 900GB drives. These trays are NOT Riverwalk 2 trays, even though the "C" series may kind of look like it. Different manufacturer and different firmware. They are not new. Like I said, we've been selling them with the 7x20 series since last January. They are the only disk trays we will be selling going forward. Of course, AK8 supports them. So what's the problem? The problem is going to be for people who have to mix drive trays. Remember, your older 7x20 series has Thebe SAS2 HBAs. These have 2 SAS ports per card.  The new ZS3-2 and ZS3-4 systems, however, have the new "Thebe2" SAS2 HBAs. These Thebe2 cards have 4 ports per card. This is very cool, as we can now do more SAS channels with less cards. Instead of needing 4 SAS cards to grow to 24 trays like we did with the old Thebe cards, I can now do 24 trays with only 2 Thebe2 cards. This means more IO slots for fun things like Infiniband and 10G. So far, so good, right? These Thebe2 cards work with any disk tray. You can even mix older DS2 trays with the newer DE2 trays in the same system, as long as you have Thebe2 cards. Ah, there's your problem. You don't have Thebe2 cards in your old 7420, do you? Well, I told you the bad news wasn't that bad, right? We can take out your Thebe cards and replace them with Thebe2. You can then plug your older DS2 trays right back in, and also now get newer DE2 trays going forward. However, it's important that the trays are on different SAS channels. You can mix them in the same system, but not on the same channel. Ask your local SC if you need help with the new cable layout. By the way, the new ZS3-2 and ZS3-4 systems also include a new IO card called "Erie" cards. These are for INTERNAL SAS to the OS drives and the Readzillas. So those are now SAS2 instead of SATA like the older models. Yes, the Erie card uses an IO slot, but that's OK, because the Thebe2 cards allow us to use less SAS HBAs to grow the system, right? That's it. Not too much bad news and really not that bad. AK8 does not support the 7x10 series, and you may need new Thebe2 cards in your older systems if you want to add on newer DE2 trays. I think we can all agree that there are worse things out there. Like our Congress.   Next up.... More good news and cool AK8 tricks. Such as virtual NICS.

• Why are my USB 2.0 devices crashing Windows XP?

  - by BenAlabaster

  Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

• System user authentication via web interface [closed]

  - by donodarazao

  Background: We have one pretty slow and expensive satellite Internet connection that is shared in a network with 5-50 users. To limit traffic, users shall pay a certain sum of money per hour. Routing and traffic accounting on user basis is done by a opensuse 10.3 server. Login is done via pppoe, and for each connection, username, bytes_sent, bytes_rcvd, start_time, end_time,etc are written into a mysql database. Now it was decided that we want to change from time-based to volume-based pricing. As the original developer who installed the system a couple of years ago isn't available, I'm trying to do the changes. Although I'm absolutely new to all this, there is some progress. However, there's one point I'm absolutely stuck. Up to now, only administrators can access connection details and billing information via a web interface. But as volume-based prices are less transparent to users than time-based prices, it is essential that users themselves can check their connections and how much they cost via the web interface. For this, we need some kind of user authentication. Actual question: How to develop such a user authentication? Every user has a linux system user account. With this user name and password, connection to the pppoe-server is made by the client machines. I thought about two possibles ways to authenticate users: First possibility: Users type username and password in a form. This is then somehow checked. We already have to possibilities to change passwords via the web interface. Here are parts of the code: Part of the Perl script the homepage is linked to: #!/usr/bin/perl use CGI; use CGI::Carp qw(fatalsToBrowser); use lib '../lib'; use own_perl_module; my @error; my $data; $query = new CGI; $username = $query->param('username') || ''; $oldpasswd = $query->param('oldpasswd') || ''; $passwd = $query->param('passwd') || ''; $passwd2 = $query->param('passwd2') || ''; own_perl_module::connect(); if ($query->param('submit')) { my $benutzer = own_perl_module::select_benutzer(username => $username) or push @error, "user not exists"; push @error, "your password?!?" unless $passwd; unless (@error) { own_perl_module::update_benutzer($benutzer->{id}, { oldpasswd => $oldpasswd, passwd => $passwd, passwd2 => $passwd2 }, error => \@error) and push @error, "Password changed."; } } Here's part of the sub update_benutzer in the own_perl_module: if ($dat-{passwd} ne '') { my $username = $dat-{username} || $select-{username}; my $system = "./chpasswd.pl '$username' '$dat-{passwd}'" . (defined($dat-{oldpasswd}) ? " '$dat-{oldpasswd}'" : undef); my $answer = $system; if ($? != 0) { chomp($answer); push @$error, $answer || "error changing password ($?)"; Here's chpasswd.pl: #!/usr/bin/perl use FileHandle; use IPC::Open3; local $username = shift; local $passwd = shift; local $oldpasswd = shift; local $chat = { 'Old Password: $' => sub { print POUT "$oldpasswd\n"; }, 'New password: $' => sub { print POUT "$passwd\n"; }, 'Re-enter new password: $' => sub { print POUT "$passwd\n"; }, '(.*)\n$' => sub { print "$1\n"; exit 1; } }; local $/ = \1; my $command; if (defined($oldpasswd)) { $command = "sudo -u '$username' /usr/bin/passwd"; } else { $command = "sudo /usr/bin/passwd '$username'"; } $pid = open3(\*POUT, \*PIN, \*PERR, $command) or die; my $buffer; LOOP: while($_ = <PERR>) { $buffer .= $_; foreach (keys(%$chat)) { if ($buffer =~ /$_/i) { $buffer = undef; &{$chat->{$_}}; } } } exit; Could this somehow be adjusted to verify users, but not changing user passwords? The second possibility I see: all pppoe connections are logged in the mysql database. If I could somehow retrieve the username (or uid) of the user connected by pppoe, this could be used to authenticate users. Users could only check their internet connections and costs when they are online (and thus paying money), but this could be tolerated. Here's a line of the script that inserts connections into the database: my $username = $ENV{PEERNAME}; I thought it would be easy to use this variable, but $username seems to be always empty in test-scripts (print $username). Any idea how to retrieve the user connected to the pppoe server? Sorry for the long question! Any help would be very much appreciated. :)

• Why are my USB 2.0 devices hanging Windows XP?

  - by BenAlabaster

  Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors - it has a NEC uPD720102 chipset. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine? Edit: Updated the USB 2.0 info with reference to actual card - http://www.xpcgear.com/lpnec4u.html

• LINQ to Twitter Maintenance Feedback

  - by Joe Mayo

  Originally posted on: http://geekswithblogs.net/WinAZ/archive/2013/06/16/linq-to-twitter-maintenance-feedback.aspxIt’s always fun to receive positive feedback on your work. If you receive a sufficient amount of positive feedback, you know you’re doing something right. Sometimes, people provide negative feedback too. There are a couple ways to handle it: come back fighting or engage for clarification. The way you handle the negative feedback depends on what your goals are. Feedback Approaches If you know the feedback is incorrect and you need to promote your idea or product, you might want to come back fighting. The feedback might just be comments by a troll or competitor wanting to spread FUD. However, this could be the totally wrong approach if you misjudge the source and intentions of the feedback. In a lot of cases, feedback is a golden opportunity. Sometimes, a problem exists that you either don’t know about or don’t realize the true impact of the problem. If you decide to come back fighting, you might loose the opportunity to learn something new. However, if you engage the person providing the feedback, looking for clarification, you might learn something very important. Negative feedback and it’s clarification can lead to the collection of useful and actionable data. In my case, something that prompted this blog post, I noticed someone who tweeted a negative comment about LINQ to Twitter. Normally, any less than stellar comments are usually from folks that need help – so I help if I can. This was different. I was like “Don’t use LINQ to Twitter”. This is an open source project, the comment didn’t come from a competing project, and  sounded more like an expression of frustration. So I engaged. Not only did the person respond, but I got some decent quality feedback. What’s also interesting is a couple other side conversations sprouted on the subject, which gave me more useful data. LINQ to Twitter Thread Actions Essentially, this particular issue centered around maintenance. There are actually several sub-issues at play here: dependencies, error handling, debugging, and visibility. I’ll describe each one and my interpretation. Dependencies Dependencies are where a library has references to other libraries. This means that when you build your application, you need DLLs for the entire dependency graph for your application. There are several potential problems with this that include more libraries for configuration management, potential versioning mismatches, and lack of cross-platform support. In the early days of LINQ to Twitter, I allowed developers to contribute and add dependencies, but it became very problematic (for reasons stated). It was like a ball and chain that kept me from moving forward. So, I refactored and pulled other open-source into my project to eliminate external dependencies. This lets me fix the code in my project without relying on someone else to upgrade or fix their DLL. The motivation for this was from early negative feedback that translated as important data and acted on it. Today, LINQ to Twitter has zero dependencies. Note: Rejecting good code from community members who worked hard to make your project better is a painful experience in itself. I have to point out that any contribution was not in vain because they had a positive influence on my subsequent refactoring that resulted in a better developer experience. Error Handling Error handling has been a problem in the past. I have this combination of supporting both synchronous and asynchronous (APM) processing that can be complex at times. Within the last 6 months, I did a fair amount of refactoring to detect errors and process them properly. I also refactored TwitterQueryException so it includes important data from Twitter. During this refactoring, I’ve made breaking changes that I felt would improve the development experience (small things like renaming a callback property to Exception, rather than Error). I think the async error handling is much better than it was a year ago. For all the work I’ve done, there is more to do. I think that a combination of more error handling support, e.g. improving semantics, and education through documentation and samples will improve the error handling story. Because of what I’ve done so far, it isn’t bad, but I see opportunities for improvement. Debugging Debugging can be painful. Here’s why: you have multiple layers of technology to navigate and figure out where the real problem is – Twitter API, Security, HTTP, LINQ to Twitter, and application. You can probably add your own nuances to that list, but the point is that debugging in this environment can be complex. I think that my plans for error handling will contribute to making the debugging process easier. However, there’s more I can do in the way of documentation and guidance. Some of the questions to be answered revolve around when something goes wrong, how does the developer figure out that there is a problem, what the problem is, and what to do about it. One example that has gone a long way to helping LINQ to Twitter developers is the 401 FAQ. A 401 Unauthorized is the error that the Twitter API returns when a use isn’t able to authenticate and is one of the most difficult problems faced by LINQ to Twitter developers. What I did was read guidance from Twitter and collect techniques from my own development and actions helping other developers to compile an extensive list of reasons for the 401 and ways to fix the problem. At one time, over half of the questions I answered in the forums were to help solve 401 issues. After publishing the 401 FAQ, I rarely get a 401 question and it’s because the person didn’t know about the FAQ. If the person is too lazy to read the FAQ, that’s not my issue, but the results in support issues have been dramatic. I think debugging can benefit from the education and documentation approach, but I’m always open to suggestions on whatever else I can do. Visibility Visibility is a nuance of the error handling/debugging discussion but is deeply rooted in comfort and control. The questions to ask in this area are what is happening as my code runs and how testable is the code. In support of these areas, LINQ to Twitter does have logging and TwitterContext properties that help see what’s happening on requests. The logging functionality allows any developer to connect a TextWriter to the Log property of TwitterContext to see what’s happening. Further, TwitterContext has a Headers property to see the headers Twitter returns and a RawResults property to show the Json string Twitter returns. From a testing perspective, I’ve been able to write hundreds of unit tests, over 600 when this post is published, and growing. If you write your own library, you have full control over all of these aspects. The tradeoff here is that while you have access to the LINQ to Twitter source code and modify it for all the visibility, LINQ to Twitter *will* change (which is good) and you will have to figure out how to merge that with your changes (which is hard). The fact is that this is a limitation of any 3rd party library, not just LINQ to Twitter. So, it’s a design decision where the tradeoff is between control and productivity. That said, there are things I can do with LINQ to Twitter to make the visibility story more compelling. I think there are opportunities to improve diagnostics. This would be a ton of work because it would need to provide multi-level logging that can be tuned for production and support any logging provider you want to attach. I’ve considered approaches such as how the new Semantic Logging application block connects to Windows Error Reporting as a potential target. Whatever I do would need to be extensible without creating native external dependencies. e.g. how many 3rd party libraries force a dependency on a logging framework that you don’t use. So, this won’t be an easy feat, but I believe it can be part of the roadmap. I think that a lot of developers are unaware of existing visibility features, so the first step would be to provide more documentation and guidance. My thought are that this would lead to more feedback that will help improve this area. Summary Recent feedback highlights some of items that are important to LINQ to Twitter developers, such as dependencies, error handling, debugging, and visibility. I know that there are maintenance issues that have been problems for LINQ to Twitter developers in the past. I’ve done a lot of work in this area, such as improving error handling, adding visibility features, and providing extensive API documentation. That said, there is more to be done to make LINQ to Twitter the best Twitter API experience available for .NET developers and I welcome anyone’s thoughts on what I’ve written here or new improvements. @JoeMayo

• My application had a WindowsIdentity crisis

  - by Brian Donahue

  The project I have been working on this week to test computer environments needs to do various actions as a user other than the one running the application. For instance, it looks up an installed Windows Service, finds out who the startup user is, and tries to connect to a database as that Windows user. Later on, it will need to access a file in the context of the currently logged-in user. With ASP .NET, this is super-easy: just go into Web.Config and set up the "identity impersonate" node, which can either impersonate a named user or the one who had logged into the website if authentication was enabled. With Windows applications, this is not so straightforward. There may be something I am overlooking, but the limitation seems to be that you can only change the security context on the current thread: any threads spawned by the impersonated thread also inherit the impersonated credentials. Impersonation is easy enough to do, once you figure out how. Here is my code for impersonating a user on the current thread:         using System;         using System.ComponentModel;         using System.Runtime.InteropServices;         using System.Security.Principal;         public class ImpersonateUser         {                 IntPtr userHandle;   [DllImport("advapi32.dll", SetLastError = true)]                 static extern bool LogonUser(                         string lpszUsername,                         string lpszDomain,                         string lpszPassword,                         LogonType dwLogonType,                         LogonProvider dwLogonProvider,                         out IntPtr phToken                         );                     [DllImport("kernel32.dll", SetLastError = true)]                 static extern bool CloseHandle(IntPtr hHandle);                     enum LogonType : int                 {                         Interactive = 2,                         Network = 3,                         Batch = 4,                         Service = 5,                         NetworkCleartext = 8,                         NewCredentials = 9,                 }                     enum LogonProvider : int                 {                         Default = 0,                 }                 public static WindowsImpersonationContext Impersonate(string user, string domain, string password)                 {   IntPtr userHandle = IntPtr.Zero;                         bool loggedOn = LogonUser(                                 user,                                 domain,                                 password,                                 LogonType.Interactive,                                 LogonProvider.Default,                                 out userHandle);                               if (!loggedOn)                         throw new Win32Exception(Marshal.GetLastWin32Error());                           WindowsIdentity identity = new WindowsIdentity(userHandle);                         WindowsPrincipal principal = new WindowsPrincipal(identity);                         System.Threading.Thread.CurrentPrincipal = principal;                         return identity.Impersonate();   }         }   /* Call impersonation */ ImpersonateUser.Impersonate("UserName","DomainName","Password"); /* When you want to go back to the original user */ WindowsIdentity.Impersonate(IntPtr.Zero); When you want to stop impersonating, you can call Impersonate() again with a null pointer. This will allow you to simulate a variety of different Windows users from the same applicaiton.

• How do i route TCP connections via TOR? [on hold]

  - by acidzombie24

  I was reading about torchat which is essentially an anonymous chat program. It sounded cool so i wanted to experiment with making my own. First i wrote a test to grab a webpage using Http. Sicne .NET doesnt support SOCKS4A/SOCKS5 i used privoxy and my app worked. Then i switch to a TCP echo test and privoxy doesnt support TCP so i searched and installed 6+ proxy apps (freecap, socat, freeproxy, delegate are the ones i can remember from the top of my head, i also played with putty bc i know it supports tunnels and SOCK5) but i couldnt successfully get any of them to work let alone get it running with my http test that privoxy easily and painlessly did. What may i use to get TCP connections going through TOR? I spent more then 2 hours without success. I don't know if i am looking for a relay, tunnel, forwarder, proxy or a proxychain which all came up in my search. I use the config below for .NET. I need TCP working but i am first testing with http since i know i had it working using privoxy. What apps and configs do i use to get TCP going through tor? <?xml version="1.0" encoding="utf-8" ?> <configuration> <system.net> <defaultProxy enabled="true"> <proxy bypassonlocal="True" proxyaddress="http://127.0.0.1:8118"/> </defaultProxy> <settings> <httpWebRequest useUnsafeHeaderParsing="true"/> </settings> </system.net> </configuration> -edit- Thanks to Bernd i have a solution. Here is the code i ended up writing. It isn't amazing but its fair. static NetworkStream ConnectSocksProxy(string proxyDomain, short proxyPort, string host, short hostPort, TcpClient tc) { tc.Connect(proxyDomain, proxyPort); if (System.Text.RegularExpressions.Regex.IsMatch(host, @"[\:/\\]")) throw new Exception("Invalid Host name. Use FQDN such as www.google.com. Do not have http, a port or / in it"); NetworkStream ns = tc.GetStream(); var HostNameBuf = new ASCIIEncoding().GetBytes(host); var HostPortBuf = BitConverter.GetBytes(IPAddress.HostToNetworkOrder(hostPort)); if (true) //5 { var bufout = new byte[128]; var buflen = 0; ns.Write(new byte[] { 5, 1, 0 }, 0, 3); buflen = ns.Read(bufout, 0, bufout.Length); if (buflen != 2 || bufout[0] != 5 || bufout[1] != 0) throw new Exception(); var buf = new byte[] { 5, 1, 0, 3, (byte)HostNameBuf.Length }; var mem = new MemoryStream(); mem.Write(buf, 0, buf.Length); mem.Write(HostNameBuf, 0, HostNameBuf.Length); mem.Write(new byte[] { HostPortBuf[0], HostPortBuf[1] }, 0, 2); var memarr = mem.ToArray(); ns.Write(memarr, 0, memarr.Length); buflen = ns.Read(bufout, 0, bufout.Length); if (bufout[0] != 5 || bufout[1] != 0) throw new Exception(); } else //4a { var bufout = new byte[128]; var buflen = 0; var mem = new MemoryStream(); mem.WriteByte(4); mem.WriteByte(1); mem.Write(HostPortBuf, 0, 2); mem.Write(BitConverter.GetBytes(IPAddress.HostToNetworkOrder(1)), 0, 4); mem.WriteByte(0); mem.Write(HostNameBuf, 0, HostNameBuf.Length); mem.WriteByte(0); var memarr = mem.ToArray(); ns.Write(memarr, 0, memarr.Length); buflen = ns.Read(bufout, 0, bufout.Length); if (buflen != 8 || bufout[0] != 0 || bufout[1] != 90) throw new Exception(); } return ns; } Usage using (TcpClient client = new TcpClient()) using (var ns = ConnectSocksProxy("127.0.0.1", 9050, "website.com", 80, client)) {...}

• Setting up Rails to work with sqlserver

  Ok I followed the steps for setting up ruby and rails on my Vista machine and I am having a problem connecting to the database. Contents of database.yml development: adapter: sqlserver database: APPS_SETUP Host: WindowsVT06\SQLEXPRESS Username: se Password: paswd Run rake db:migrate from myapp directory ---------- rake aborted! no such file to load -- deprecated ADO I have dbi 0.4.0 installed and have created the ADO folder in C:\Ruby\lib\ruby\site_ruby\1.8\DBD\ADO I got the ado.rb from the dbi 0.2.2 What else should I be looking at to fix the issue connecting to the database?

• WPF TabItem Custom ContentTemplate

  - by lloydsparkes

  I have been strugging with this for a while, it would have been simple to do in WindowForms. I am making a IRC Client, there will be a number of Tabs one for each channel connect to. Each Tab needs to show a number of things, UserList, MessageHistory, Topic. In WindowForms i would just have inherited from TabItem, added some Custom Properties, and Controls, and done. In WPF i am having some slight issues with working out how to do it. I have tried many ways of doing it, and below is my current method, but i cannot get the TextBox to bind to the Topic Property. <Style TargetType="{x:Type t:IRCTabItem}" BasedOn="{StaticResource {x:Type TabItem}}" > <Setter Property="ContentTemplate"> <Setter.Value> <DataTemplate> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="540" /> <ColumnDefinition /> </Grid.ColumnDefinitions> <StackPanel Grid.Column="0"> <TextBox Text="{Binding Topic, RelativeSource={RelativeSource AncestorType={x:Type t:IRCTabItem}}}" /> </StackPanel> </Grid> </DataTemplate> </Setter.Value> </Setter> </Style> And the Codebehind public class IRCTabItem : TabItem { static IRCTabItem() { //This OverrideMetadata call tells the system that this element wants to provide a style that is different than its base class. //This style is defined in themes\generic.xaml //DefaultStyleKeyProperty.OverrideMetadata(typeof(IRCTabItem), // new FrameworkPropertyMetadata(typeof(IRCTabItem))); } public static readonly RoutedEvent CloseTabEvent = EventManager.RegisterRoutedEvent("CloseTab", RoutingStrategy.Bubble, typeof(RoutedEventHandler), typeof(IRCTabItem)); public event RoutedEventHandler CloseTab { add { AddHandler(CloseTabEvent, value); } remove { RemoveHandler(CloseTabEvent, value); } } public override void OnApplyTemplate() { base.OnApplyTemplate(); Button closeButton = base.GetTemplateChild("PART_Close") as Button; if (closeButton != null) closeButton.Click += new System.Windows.RoutedEventHandler(closeButton_Click); } void closeButton_Click(object sender, System.Windows.RoutedEventArgs e) { this.RaiseEvent(new RoutedEventArgs(CloseTabEvent, this)); } public bool Closeable { get; set; } public static readonly DependencyProperty CloseableProperty = DependencyProperty.Register("Closeable", typeof(bool), typeof(IRCTabItem), new FrameworkPropertyMetadata(true, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); public List<String> UserList { get; set; } public static readonly DependencyProperty UserListProperty = DependencyProperty.Register("UserList", typeof(List<String>), typeof(IRCTabItem), new FrameworkPropertyMetadata(new List<String>(), FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); public String Topic { get; set; } public static readonly DependencyProperty TopicProperty = DependencyProperty.Register("Topic", typeof(String), typeof(IRCTabItem), new FrameworkPropertyMetadata("Not Connected", FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); public bool HasAlerts { get; set; } public static readonly DependencyProperty HasAlertsProperty = DependencyProperty.Register("HasAlerts", typeof(bool), typeof(IRCTabItem), new FrameworkPropertyMetadata(false, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault)); } So my questions are: Am i doing it the right way (best practices)? If so how can i bind DataTemplate to Properties? If not so, what is the correct way of achieve what i am trying to achieve?

• send multiple file over TCP with C# using TcpClient

  - by xnoor

  I'm trying to send multiple files over TCP using C# TcpClient, for a single file it works great, but when I have multiple files, it sends only the first one. Here is my code: SENDING FILES try { TcpClient tcpClient = new TcpClient(); NetworkStream networkStream; FileStream fileStream = null; tcpClient.Connect(appUpdateMessage.receiverIpAddress, 12000); networkStream = tcpClient.GetStream(); byte[] byteSend = new byte[tcpClient.ReceiveBufferSize]; string startupPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6); DirectoryInfo directoriesInfo = new DirectoryInfo(startupPath); DirectoryInfo[] directories = directoriesInfo.GetDirectories(); FileInfo[] files = directoriesInfo.GetFiles(); for (int iLoop = 0; iLoop < directories.Length; iLoop++) { FileInfo[] subdirectoryFiles = directories[iLoop].GetFiles(); foreach (FileInfo fi in subdirectoryFiles) { fileStream = new FileStream(fi.FullName, FileMode.Open, FileAccess.Read); BinaryReader binFile = new BinaryReader(fileStream); FileUpdateMessage fileUpdateMessage = new FileUpdateMessage(); fileUpdateMessage.fileName = fi.Name; fileUpdateMessage.fileSize = fi.Length; fileUpdateMessage.targetDirectory = fi.Directory.Name; MessageContainer messageContainer = new MessageContainer(); messageContainer.messageType = MessageType.FileProperties; messageContainer.messageContnet = SerializationManager.XmlFormatterObjectToByteArray(fileUpdateMessage); byte[] messageByte = SerializationManager.XmlFormatterObjectToByteArray(messageContainer); networkStream.Write(messageByte, 0, messageByte.Length); int bytesSize = 0; byte[] downBuffer = new byte[2048]; while ((bytesSize = fileStream.Read(downBuffer, 0, downBuffer.Length)) > 0) { networkStream.Write(downBuffer, 0, bytesSize); } fileStream.Close(); } } tcpClient.Close(); networkStream.Close(); return true; } catch (Exception ex) { //logger.Info(ex.Message); return false; } finally { } RECEIVING FILES try { TcpClient tcpClient = c as TcpClient; NetworkStream networkstream = tcpClient.GetStream(); FileStream fileStream = null; byte[] _data = new byte[1024]; int _bytesRead = 0; _bytesRead = networkstream.Read(_data, 0, _data.Length); MessageContainer messageContainer = new MessageContainer(); messageContainer = SerializationManager.XmlFormatterByteArrayToObject(_data, messageContainer) as MessageContainer; switch (messageContainer.messageType) { case MessageType.FileProperties: FileUpdateMessage fileUpdateMessage = new FileUpdateMessage(); fileUpdateMessage = SerializationManager.XmlFormatterByteArrayToObject(messageContainer.messageContnet, fileUpdateMessage) as FileUpdateMessage; string startupPath = @"d:updatefolder";//System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6); DirectoryInfo mainDirectory = new DirectoryInfo(startupPath); DirectoryInfo targetDirecotry = new DirectoryInfo(startupPath + "\\" + fileUpdateMessage.targetDirectory); if (!targetDirecotry.Exists) { mainDirectory.CreateSubdirectory(fileUpdateMessage.targetDirectory); } fileStream = new FileStream(startupPath + "\\" + fileUpdateMessage.targetDirectory + "\\" + fileUpdateMessage.fileName, FileMode.Create, FileAccess.Write, FileShare.ReadWrite); long filezie = fileUpdateMessage.fileSize; int byteSize = 0; byte[] downBuffer = new byte[2048]; while ((byteSize = networkstream.Read(downBuffer, 0, downBuffer.Length)) > 0) { fileStream.Write(downBuffer, 0, byteSize); if (this.InvokeRequired) { this.Invoke((MethodInvoker)delegate { //progressBar1.Value = Convert.ToInt32((byteSize * 100) / fileUpdateMessage.fileSize); progressBar1.Value = Convert.ToInt32((fileStream.Length * 100) / fileUpdateMessage.fileSize); lblFileName.Text = fileUpdateMessage.fileName; }); } else { //progressBar1.Value = Convert.ToInt32((byteSize * 100) / fileUpdateMessage.fileSize); lblFileName.Text = fileUpdateMessage.fileName; } } fileStream.Close(); networkstream.Close(); break; } } catch (Exception ex) { //logger.Error(ex.Message); } Any idea what I am doing wrong?

• WCF app Deployed on Win7 Machine and get connection refused error

  - by Belliez

  I have created a Sync Framework application based on the following sample from microsoft and deployed it to a new Windows 7 machine for testing. The app runs ok but when I attempt to communicate I get the following error: Could not connect to http://localhost:8000/RelationalSyncContract/SqlSyncService/. TCP error code 10061: No connection could be made because the target machine actively refused it 127.0.0.1:8000. I am wondering if there is something I am missing. This is my first experience using WCF and followed microsoft sample code. I have disabled the firewall and opened port 8000 for both TCP and UDP. Not sure what to look at next. Below is my App.config file if this helps: <?xml version="1.0"?> <configuration> <system.web> <compilation debug="true"/> <httpRuntime maxRequestLength="32768" /> </system.web> <!-- When deploying the service library project, the content of the config file must be added to the host's app.config file.

• Call Webservice without adding a WebReference - with Complex Types

  - by ck

  I'm using the code at This Site to call a webservice dynamically. [SecurityPermissionAttribute(SecurityAction.Demand, Unrestricted = true)] public static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args) { System.Net.WebClient client = new System.Net.WebClient(); //-Connect To the web service using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl")) { //--Now read the WSDL file describing a service. ServiceDescription description = ServiceDescription.Read(stream); ///// LOAD THE DOM ///////// //--Initialize a service description importer. ServiceDescriptionImporter importer = new ServiceDescriptionImporter(); importer.ProtocolName = "Soap12"; // Use SOAP 1.2. importer.AddServiceDescription(description, null, null); //--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client; //--Generate properties to represent primitive values. importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties; //--Initialize a Code-DOM tree into which we will import the service. CodeNamespace nmspace = new CodeNamespace(); CodeCompileUnit unit1 = new CodeCompileUnit(); unit1.Namespaces.Add(nmspace); //--Import the service into the Code-DOM tree. This creates proxy code //--that uses the service. ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1); if (warning == 0) //--If zero then we are good to go { //--Generate the proxy code CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp"); //--Compile the assembly proxy with the appropriate references string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" }; CompilerParameters parms = new CompilerParameters(assemblyReferences); CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1); //-Check For Errors if (results.Errors.Count > 0) { StringBuilder sb = new StringBuilder(); foreach (CompilerError oops in results.Errors) { sb.AppendLine("========Compiler error============"); sb.AppendLine(oops.ErrorText); } throw new System.ApplicationException("Compile Error Occured calling webservice.

The classes reference the same assembly and the same version. Do I need to include my assembly as a reference when building the temporary assembly? If so, how? Thanks.

• Rendering a WPF Network Map/Graph layout - Manual? PathListBox? Something Else?

  - by Ben Von Handorf

  I'm writing code to present the user with a simplified network map. At any given time, the map is focused on a specific item... say a router or a server. Based on the focused item, other network entities are grouped into sets (i.e. subnets or domains) and then rendered around the focused item. Lines would represent connections and groups would be visually grouped inside a rectangle or ellipse. Panning and zooming are required features. An item can be selected to display more information in a "properties" style window. An item could also be double-clicked to re-focus the entire network map on that item. At that point, the entire map would be re-calculated. I am using MVVM without any framework, as of yet. Assume the logic for grouping items and determining what should be shown or not is all in place. I'm looking for the best way to approach the UI layout. So far, I'm aware of the following options: Use a canvas for layout (inside a ScrollViewer to handle the panning). Have my ViewModel make use of a Layout Manager type of class, which would handle assigning all the layout properties (Top, Left, etc.). Bind my set of display items to an ItemsControl and use Data Templates to handle the actual rendering. The drawbacks with this approach: Highly manual layout on my part. Lots of calculation. I have to handle item selection manually. Computation of connecting lines is manual. The Pros of this approach: I can draw additional lines between child subnets as appropriate (manually). Additional LayoutManagers could be added later to render the display differently. This could probably be wrapped up into some sort of a GraphLayout control to be re-used. Present the focused item at the center of the display and then use a PathListBox for layout of the additional items. Have my ViewModel expose a simple list of things to be drawn and bind them to the PathListBox. Override the ListBoxItem Template to also create a line geometry from the borders of the focused item (tricky) to the bound item. Use DataTemplates to handle the case where the item being bound is a subnet, in which case we would use another PathListBox in the template to display items inside the subnet. The drawbacks with this approach: Selected Item synchronization across multiple `PathListBox`es. Only one item on the whole graph can be selected at a time, but each child PathListBox maintains its own selection. Also, subnets cannot be selected, but would be selectable without additional work. Drawing the connecting lines is going to be a bit of trickery in the ListBoxItem template, since I need to know the correct side of the focused item to connect to. The pros of this approach: I get to stay out of the layout business, more. I'm looking for any advice or thoughts from others who have encountered similar issues or who have more WPF experience than I. I'm using WPF 4, so any new tricks are legal and encouraged.
