SSH host key fingerprint does not match pattern C# WinSCP -


i trying connect ftps server using c# via winscp , getting error:

ssh host key fingerprint ... not match pattern ...

after tons of research, believe has length of key. key got winscp when connected using interface under "server , protocol information" xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx ones saw in example shorter xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx

can please , offer me pointer resolve appreciated.

here code

string winscppath = "c:\\program files (x86)\\winscp\\winscp.exe"; string username = "user123"; string password = "abc1234"; string ftpsite = "192.168.5.110"; string localpath = "c:\\users\\ttom\\documents"; string remoteftpdirectory = "/usr/thisfolder"; string sshkey = "1b:68:10:80:77:c6:65:91:51:31:5t:65:1c:g6:13:20:39:g8:d8:6d"; boolean winscplog = true; string winscplogpath = "c:\\users\\ttom\\documents\\visual studio 2015\\projects\\webapplication1\\webapplication1";  sessionoptions sessionoptions = new sessionoptions {     protocol = protocol.sftp,     hostname = ftpsite,     username = username,     password = password,     sshhostkeyfingerprint = sshkey };  using (session session = new session()) {     // winscp .net assembly must in gac used ssis,     // set path winscp.exe explicitly, if using non-default path.     session.executablepath = winscppath;     session.disableversioncheck = true;      if (winscplog)     {         session.sessionlogpath = @winscplogpath + @"ftplog.txt";         session.debuglogpath = @winscplogpath + @"debuglog.txt";     }      // connect     session.timeout = new timespan(0, 2, 0); // 2 minutes     session.open(sessionoptions);      transferoptions transferoptions = new transferoptions();     transferoptions.transfermode = transfermode.binary;      session.getfiles(remoteftpdirectory + "/" +         "test.txt", localpath, false, transferoptions); }

enter image description here

you connecting using sftp (over ssh) in code, using ftps (ftp on tls/ssl) in gui.

these 2 completely different protocols.

use protocol = protocol.ftp , enable tls/ssl using ftpsecure = ftpsecure.explicit.

sessionoptions sessionoptions = new sessionoptions {     protocol = protocol.ftp,     ftpsecure = ftpsecure.explicit,     hostname = ftpsite,     username = username,     password = password, };

an equivalent of sshhostkeyfingerprint ftps tlshostcertificatefingerprint. need use when tls/ssl certificate not signed trusted authority (e.g. self signed certificate).

the easiest 5.8.x (beta currently) , use generate code function. can use generated code stable version of winscp .net assembly.

i have read ( how make choices in radiobuttons reactive in shiny? ) shows me how update radiobutton s in reactive way. however, when try , update 2 sets of buttons same data, 1 set renders. example: server: # create example data wafer <- rep(c(1:3), each=3) length <- c(1,1,2,1,1,1,3,5,1) width <- c(3,1,6,1,1,1,1,1,6) dd <- data.frame(wafer, length, width) shinyserver(function(input, output, session){ # create reactive dataframe store data values <- reactivevalues() values$df <- data.frame() # lengths , widths of wafer user input <- eventreactive(input$do, { subset(dd, wafer %in% input$wafer, select = length:width) }) # update reactive data frame lengths , widths have been selected user input observe({ if(!is.null(a())) { values$df <- rbind(isolate(values$df), a()) } }) output$wl <- renderdatatable({ a() }) # update radio buttons unique length , widths stored in values$df # ever "observe" put first in co...

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -

i'm working on app using core data , nsfetchedresultcontroller many reasons switch use realm. saw there "realm version" of nsfetchedresultcontroller on github wouldn't compatible current code using core data. the view controller displaying list of people same school, address book. list sublist of people studied in same city. so thinking make 1 unique request database retrieve list of people , filter locally list within 1 dictionary per school [string: anyobject] string section name within tableview , anyobject array of people. first solution, make nsfetchedresultcontroller each school predicate filtering location. delete actions etc.. handled delegates -> not compatible realm create dictionaries , update them each actions... -> works realm it's annoying code. any better solution? edit: i need clarify request: i'd write class inherit uitableviewcontroller. this class has list of people sorted in alphabetical order the tableview has ...
