Capture output of ssh connection to SonicWall in vb.net -


i'm surprised isn't out there already, guess needs trailblazer. ok, part of pci compliance firewall rules need reviewed periodically. thought doing right, apparently not. i've been put on correct path , trying automation possible. end, trying connect sonicwall firewall using .net program (specifically vb.net) (that trying write) , execute following command "show nat-policies xml" , capture xml output (i service groups, address objects , address groups), shred in database.

initially, tried ssh.net giving me error connection being closed. little research says ssh.net has issues trying connect sonicwall firewall , should try using tamir.sharpssh. tried that, first attempt, when executed connect statement, waited didn't move past statement. tried second example , complained host keys.

i know sonicwall firewall configured ssh because can connect using putty , information (in convoluted way, can it). here code call hangs:

imports tamir.sharpssh imports tamir.sharpssh.jsch imports system.io imports system.threading imports org.mentalis.security public class form1 private sub form1_load(sender object, e eventargs) handles mybase.load try dim cssh new sshshell("192.168.000.000", "username", "user password") cssh.connect()      'freezes here using sstream sshstream = cssh.getstream()             dim wrtr new streamwriter(sstream)             dim rdr new streamreader(sstream)             wrtr.autoflush = true             writestream("show nat-policies xml", wrtr, sstream)             readstream(rdr)         end using     catch ex exception         textbox1.text = ex.message             textbox1.appendtext(vbcrlf + "finished")     end try end sub private sub writestream(byval cmd string, byval wrtr streamwriter, byval sstrm sshstream)     wrtr.writeline(cmd)     while sstrm.length = 0         thread.sleep(500)     end while end sub private sub readstream(byval sreader streamreader)     dim line string = sreader.readline()     while not string.isnullorempty(line)         textbox1.appendtext(vbcrlf + line)         line = sreader.readline()     end while end sub end class

any ideas?

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
