Bash extracting name servers including if they are on new line, using whois -

-

Hi friends, I'm trying to remove name servers from websites, but I think that if the server is a new line As if I can do it like this happens .... 

  nserver: ns-a.somesite.com 176.195.2.100 nserver: ns-b.somesite.com 176.195 .2.101   
 But if so, then I can not do it:  
  nserver: ns-a.somesite.com 176.195.2.100 ns-b. Somesite.com 176.195.2.101 Ns-b.somesite.com 176.195.2.102   
 This is what I have done so far:  
  whois ebay.com | Grep -E "[SS] errors {0,1}:"    
 
 
 Name of the name server only:  
  whois ebay.com | Grep -E "Name Server" | Tr-d '' | | With GP's search criteria, Monkey may look like your output, but you should get it 99%. The way is there.  
 For reference only, it will repeat lines with "name server", it will remove the spaces from the line, then it will divide the line by a colon and print the other element, which is the name server .  
 Renewed  
 Added for hard examples:  
  whois sans.edu | Tr-d '' | | Awk -F: '{if ($ 1 == "Name Server" & Length ($ 2) & gt; 0) Print $ 2; And if found ($ 0 == "name server:") = 1; And if (found == 1 & amp; Length ($ 0)> 0) print $ 0; Other found = 0} '  
 This is a little maser. After removing the empty space, we do the following in OK to make the awk:  
     
  •  We are divided by colon.  
  •  If $ 1 is equal to "nameserver" and length $ 2 & gt; 0 Then we print $ 2 (ebay.com example)  
  •  Otherwise if the "name server:" (sans.edu example) line, we found a flag  = 1  
  •  otherwise set the flag to 0 (say we have a 0 Character length is found)

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
