• 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.

• Removing google mail markers with jquery after getting them from xml

  - by sebastian

  Hi there, I'm trying to create a page that contains a google map. The map is filled with markers from an xml file. I just can't figure out how to remove "old" markers, that don't match the latest user input. At the moment my js stops after the very first xml item. The clearList.push(marker); is supposed to put the generated marker away for later usage. When the user hits the search button I want all markers to be gone and use clearMarkers();. Maybe someone here can help Sebastian Here is my JavaScript: $(document).ready(function() { $("#map").css({height: 650}); var clearList = []; var myLatLng = new google.maps.LatLng(52.518143, 13.372879); MYMAP.init('#map', myLatLng, 11); $("#showmarkers").click(function(e){ clearMarkers(); MYMAP.placeMarkers('markers.xml'); }); }); function clearMarkers() { $(clearList).each(function () { this.setmap(null); }); clearList = []; } var MYMAP = { map: null, bounds: null } MYMAP.init = function(selector, latLng, zoom) { var myOptions = { zoom:zoom, center: latLng, mapTypeId: google.maps.MapTypeId.HYBRID } this.map = new google.maps.Map($(selector)[0], myOptions); this.bounds = new google.maps.LatLngBounds(); } MYMAP.placeMarkers = function(filename) { $.get(filename, function(xml){ $(xml).find("marker").each(function(){ // read values from xml for searching var platzart = $(this).find('platzart').text(); var ort = $(this).find('ort').text(); var open = $(this).find('open').text(); if (platzart =="Kunstrasen" && $('#kunstrasen').attr('checked') || platzart =="Rasen" && $('#rasen').attr('checked') || platzart =="Tartan" && $('#tartan').attr('checked') || platzart =="Boltzplatz" && $('#boltzplatz').attr('checked') ){ // read values from xml for additional info var name = $(this).find('name').text(); var plz = $(this).find('plz').text(); var note = $(this).find('note').text(); var adress = $(this).find('adress').text(); // create a new LatLng point for the marker var lat = $(this).find('lat').text(); var lng = $(this).find('lng').text(); var point = new google.maps.LatLng(parseFloat(lat),parseFloat(lng)); // extend the bounds to include the new point MYMAP.bounds.extend(point); // create new marker var marker = new google.maps.Marker({ position: point, map: MYMAP.map }); clearList.push(marker); // add onclick overlay var infoWindow = new google.maps.InfoWindow(); var html='<strong>'+name+'</strong.><br />'+platzart; google.maps.event.addListener(marker, 'click', function() { infoWindow.setContent(html); infoWindow.open(MYMAP.map, marker); }); } MYMAP.map.fitBounds(MYMAP.bounds); }); }); } Thanks in advance

• Step by Step / Deep explain: The Power of (Co)Yoneda (preferably in scala) through Coroutines

  - by Mzk

  some background code /** FunctorStr: ? F[-]. (? A B. (A -> B) -> F[A] -> F[B]) */ trait FunctorStr[F[_]] { self => def map[A, B](f: A => B): F[A] => F[B] } trait Yoneda[F[_], A] { yo => def apply[B](f: A => B): F[B] def run: F[A] = yo(x => x) def map[B](f: A => B): Yoneda[F, B] = new Yoneda[F, B] { def apply[X](g: B => X) = yo(f andThen g) } } object Yoneda { implicit def yonedafunctor[F[_]]: FunctorStr[({ type l[x] = Yoneda[F, x] })#l] = new FunctorStr[({ type l[x] = Yoneda[F, x] })#l] { def map[A, B](f: A => B): Yoneda[F, A] => Yoneda[F, B] = _ map f } def apply[F[_]: FunctorStr, X](x: F[X]): Yoneda[F, X] = new Yoneda[F, X] { def apply[Y](f: X => Y) = Functor[F].map(f) apply x } } trait Coyoneda[F[_], A] { co => type I def fi: F[I] def k: I => A final def map[B](f: A => B): Coyoneda.Aux[F, B, I] = Coyoneda(fi)(f compose k) } object Coyoneda { type Aux[F[_], A, B] = Coyoneda[F, A] { type I = B } def apply[F[_], B, A](x: F[B])(f: B => A): Aux[F, A, B] = new Coyoneda[F, A] { type I = B val fi = x val k = f } implicit def coyonedaFunctor[F[_]]: FunctorStr[({ type l[x] = Coyoneda[F, x] })#l] = new CoyonedaFunctor[F] {} trait CoyonedaFunctor[F[_]] extends FunctorStr[({type l[x] = Coyoneda[F, x]})#l] { override def map[A, B](f: A => B): Coyoneda[F, A] => Coyoneda[F, B] = x => apply(x.fi)(f compose x.k) } def liftCoyoneda[T[_], A](x: T[A]): Coyoneda[T, A] = apply(x)(a => a) } Now I thought I understood yoneda and coyoneda a bit just from the types – i.e. that they quantify / abstract over map fixed in some type constructor F and some type a, to any type B returning F[B] or (Co)Yoneda[F, B]. Thus providing map fusion for free (? is this kind of like a cut rule for map ?). But I see that Coyoneda is a functor for any type constructor F regardless of F being a Functor, and that I don't fully grasp. Now I'm in a situation where I'm trying to define a Coroutine type, (I'm looking at https://www.fpcomplete.com/school/to-infinity-and-beyond/pick-of-the-week/coroutines-for-streaming/part-2-coroutines for the types to get started with) case class Coroutine[S[_], M[_], R](resume: M[CoroutineState[S, M, R]]) sealed trait CoroutineState[S[_], M[_], R] object CoroutineState { case class Run[S[_], M[_], R](x: S[Coroutine[S, M, R]]) extends CoroutineState[S, M, R] case class Done[R](x: R) extends CoroutineState[Nothing, Nothing, R] class CoroutineStateFunctor[S[_], M[_]](F: FunctorStr[S]) extends FunctorStr[({ type l[x] = CoroutineState[S, M, x]})#l] { override def map[A, B](f : A => B) : CoroutineState[S, M, A] => CoroutineState[S, M, B] = { ??? } } } and I think that if I understood Coyoneda better I could leverage it to make S & M type constructors functors way easy, plus I see Coyoneda potentially playing a role in defining recursion schemes as the functor requirement is pervasive. So how could I use coyoneda to make type constructors functors like for example coroutine state? or something like a Pause functor ?

• Why does ssh hang after "debug1: loaded 3 keys"

  - by James Moore

  Trying to log in to an Amazon EC2 instance running Ubuntu 10.04.1. I can log in just fine, no issues. A different user, coming from a different network just gets this: OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 debug1: Reading configuration data /etc/ssh/ssh_config debug1: Applying options for * debug1: Connecting to xxxx [xxxx] port 80. debug1: Connection established. debug1: identity file /.ssh/identity type -1 debug1: identity file /.ssh/id_rsa type -1 debug1: identity file /.ssh/id_dsa type -1 debug1: loaded 3 keys And then it hangs. We've tried running sshd on port 22 and port 80 I'm guessing that it's not a firewall problem since the verbose output reports that the connection is established. I don't see anything in /var/log/auth.log when the failing user connects. I do see entries when I log in successfully.

• ssh tunnel error "ssh_exchange_identification: Connection closed by remote host"

  - by Jacob Ewing

  I'm trying to use an ssh tunnel from my office machine to my home machine, and get an error when I try to use it. What I'm doing is starting one shell like so: ssh -gL 12345:my.home.domain:22 my.home.domain This is giving me a proper shell, no problem. What I normally do then is ssh to my home machine through this office machine, like so: ssh -p 12345 127.0.0.1 This has always worked for me, until last week, when I set up a new system on my home machine (switching from Ubuntu to Debian). Now I get an error. I can still open up my initial ssh connection, but when I try to use that tunnel, I get (on the office machine) this error: ssh_exchange_identification: Connection closed by remote host Also, when that happens, the open shell that I have the tunnelling set up through gets this line spat out at it: channel 3: open failed: connect failed: Connection timed out At which point, I'm at a loss. If any more info is needed, I'll be happy to post it. ============= further to that ============== After fiddling around further, I've found that I'm getting a different response from the server (my home machine that is) when I try to telnet in on the various ports. If I try: telnet my.home.domain 22 I get this back: Trying <my ip address>... Connected to <my domain>. Escape character is '^]'. SSH-2.0-OpenSSH_5.5p1 Debian-6+squeeze2 Which is what I would expect. After setting up the tunnel though, and then telnetting to that, I see this response: Trying 127.0.0.1... Connected to 127.0.0.1. Escape character is '^]'. ============== and further still ================== As per kbulgrien's suggestion, here is the output from the client machine with the -v option: ssh -vp 24600 127.0.0.1 OpenSSH_5.9p1 Debian-5ubuntu1, OpenSSL 1.0.1 14 Mar 2012 debug1: Reading configuration data /etc/ssh/ssh_config debug1: /etc/ssh/ssh_config line 19: Applying options for * debug1: Connecting to 127.0.0.1 [127.0.0.1] port 24600. debug1: Connection established. debug1: identity file /home/jacob/.ssh/id_rsa type -1 debug1: identity file /home/jacob/.ssh/id_rsa-cert type -1 debug1: identity file /home/jacob/.ssh/id_dsa type -1 debug1: identity file /home/jacob/.ssh/id_dsa-cert type -1 debug1: identity file /home/jacob/.ssh/id_ecdsa type -1 debug1: identity file /home/jacob/.ssh/id_ecdsa-cert type -1 ssh_exchange_identification: Connection closed by remote host

• Tasks not appearing in Mac Outlook 2011

  - by Tama

  My current workplace uses Macs and my old workplaces used Windows. In my old workplaces I heavily used Outlook's Task functionality to manage my workload. I understand that the Task functionality in Outlook 2011 for Mac is heavily limited so I was very pleased to find this useful "how-to" on making the most of Tasks. My problem is that my tasks don't appear in the Task folder, or anywhere else for that matter. Even if I search for a the title of a task I've recently found I still can't find them. After some Googling I found this forum thread that suggests it may be a problem with the Outlook database, which points to a Microsoft KB. So I went through all of the recommended steps on rebuilding/ adding a new identity using the "Microsoft Database Utility" - the theory being that if I create a new identity I can test the task creation using a "blank slate" identity. When I change the default identity to my newly created identity using the Microsoft Database Utility (have to restart the computer) Task creation still doesn't work. Any ideas appreciated, I really miss the task functionality in Outlook 2010 for Windows.

• How to tunnel a local port onto a remote server

  - by Trevor Rudolph

  I have a domain that i bought from DynDNS. I pointed the domain at my ip adress so i can run servers. The problem I have is that I don't live near the server computer... Can I use an ssh tunnel? As I understand it, this will let me access to my servers. I want the remote computer to direct traffic from port 8080 over the ssh tunnel to the ssh client, being my laptop's port 80.

• SSH hangs without password prompt

  - by Wilco

  Just reinstalled OS X and for some reason I now cannot connect to a specific machine on my local network via SSH. I can SSH to other machines on the network without any problems, and other machines can SSH to the problematic one as well. I'm not sure where to start looking for problems - can anyone point me in the right direction?

• IPSEC site-to-site Openswan to Cisco ASA

  I recieved a list of commands that were run on the right side of the VPN tunnel which is where the Cisco ASA resides. On my side, I have a linux based firewall running debian with openswan installed. I am having an issue with getting to Phase 2 of the VPN negotiation.

Also, I read a few artilcle where configs contained the interface="ipsec0=eth0", is this an interface that I have to create on the linux debian firewall on my side? Appreciate your time to look at this.

• Can't SSH to remote server,how to avoid this

  - by snow8261

  From time to time,we suffer problems like we can not remote connect to our server via ssh.So we have to send someone on site to restart the computer for this problem.It causes a lot of pain.The situation is we have to remote connect to our server,which are very important like database server and application server and etc.We have met problems like ssh hang,like command ssh [email protected] with no response. when using ssh -v debug mode, it says : debug1: Connection established. debug1: identity file /.ssh/identity type -1 debug1: identity file /.ssh/id_rsa type -1 debug1: identity file /.ssh/id_dsa type -1 debug1: loaded 3 keys and we met this situation many times with no clue how to solve it.Is any log which can identify this problem? or Is there a tool for this problem? help needed!Any idea are appreciated.

• Passwordless SSH not working - keys copied and permissions set

  - by Comcar

  I know this question has been asked, but I'm certain I've done what all the other answers suggest. Machine A: used keygen -t rsa to create id_rsa.pub in ~/.ssh/ copied Machine A's id_rsa.pub to Machine B user's home directory Made the file permissions of id_rsa.pub 600 Machine B added Machine A's pub key to authorised_keys and authorised_keys2: cat ~/id_rsa.pub ~/.ssh/authorised_keys2 made the file permissions of id_rsa.pub 600 I've also ensured both the .ssh directories have the permission 700 on both machine A and B. If I try to login to machine B from machine A, I get asked for the password, not the ssh pass phrase. I've got the root users on both machines to talk to each other using password-less ssh, but I can't get a normal user to do it. Do the user names have to be the same on both sides? Or is there some setting else where I've missed. Machine A is a Ubuntu 10.04 virtual machine running inside VirtualBox on a Windows 7 PC, Machine B is a dedicated Ubuntu 9.10 server UPDATE : I've run ssh with the option -vvv, which provides many many lines of output, but this is the last few commands: debug3: check_host_in_hostfile: filename /home/pete/.ssh/known_hosts debug3: check_host_in_hostfile: match line 1 debug1: Host '192.168.1.19' is known and matches the RSA host key. debug1: Found key in /home/pete/.ssh/known_hosts:1 debug2: bits set: 504/1024 debug1: ssh_rsa_verify: signature correct debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug3: Wrote 16 bytes for a total of 1015 debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug3: Wrote 48 bytes for a total of 1063 debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: /home/pete/.ssh/identity ((nil)) debug2: key: /home/pete/.ssh/id_rsa (0x7ffe1baab9d0) debug2: key: /home/pete/.ssh/id_dsa ((nil)) debug3: Wrote 64 bytes for a total of 1127 debug1: Authentications that can continue: publickey,password debug3: start over, passed a different list publickey,password debug3: preferred gssapi-keyex,gssapi-with-mic,gssapi,publickey,keyboard-interactive,password debug3: authmethod_lookup publickey debug3: remaining preferred: keyboard-interactive,password debug3: authmethod_is_enabled publickey debug1: Next authentication method: publickey debug1: Trying private key: /home/pete/.ssh/identity debug3: no such identity: /home/pete/.ssh/identity debug1: Offering public key: /home/pete/.ssh/id_rsa debug3: send_pubkey_test debug2: we sent a publickey packet, wait for reply debug3: Wrote 368 bytes for a total of 1495 debug1: Authentications that can continue: publickey,password debug1: Trying private key: /home/pete/.ssh/id_dsa debug3: no such identity: /home/pete/.ssh/id_dsa debug2: we did not send a packet, disable method debug3: authmethod_lookup password debug3: remaining preferred: ,password debug3: authmethod_is_enabled password debug1: Next authentication method: password

• OpenSSH does not accept public key?

  - by Bob

  I've been trying to solve this for a while, but I'm admittedly quite stumped. I just started up a new server and was setting up OpenSSH to use key-based SSH logins, but I've run into quite a dilemma. All the guides are relatively similar, and I was following them closely (despite having done this once before). I triple checked my work to see if I would notice some obvious screw up - but nothing is apparent. As far as I can tell, I haven't done anything wrong (and I've checked very closely). If it's any help, on my end I'm using Cygwin and the server is running Ubuntu 12.04.1 LTS. Anyways, here is the output (I've removed/censored some parts for privacy (primarily anything with my name, website, or its IP address), but I can assure you that nothing is wrong there): $ ssh user@host -v OpenSSH_5.9p1, OpenSSL 0.9.8r 8 Feb 2011 debug1: Connecting to host [ipaddress] port 22. debug1: Connection established. debug1: identity file /home/user/.ssh/id_rsa type 1 debug1: identity file /home/user/.ssh/id_rsa-cert type -1 debug1: identity file /home/user/.ssh/id_dsa type -1 debug1: identity file /home/user/.ssh/id_dsa-cert type -1 debug1: identity file /home/user/.ssh/id_ecdsa type -1 debug1: identity file /home/user/.ssh/id_ecdsa-cert type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.9p1 Debian-5ubuntu1 debug1: match: OpenSSH_5.9p1 Debian-5ubuntu1 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.9 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: sending SSH2_MSG_KEX_ECDH_INIT debug1: expecting SSH2_MSG_KEX_ECDH_REPLY debug1: Server host key: ECDSA 24:68:c3:d8:13:f8:61:94:f2:95:34:d1:e2:6d:e7:d7 debug1: Host 'host' is known and matches the ECDSA host key. debug1: Found key in /home/user/.ssh/known_hosts:2 debug1: ssh_ecdsa_verify: signature correct debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug1: SSH2_MSG_NEWKEYS received debug1: Roaming not allowed by server debug1: SSH2_MSG_SERVICE_REQUEST sent debug1: SSH2_MSG_SERVICE_ACCEPT received debug1: Authentications that can continue: publickey debug1: Next authentication method: publickey debug1: Offering RSA public key: /home/user/.ssh/id_rsa debug1: Authentications that can continue: publickey debug1: Trying private key: /home/user/.ssh/id_dsa debug1: Trying private key: /home/user/.ssh/id_ecdsa debug1: No more authentication methods to try.
