  • 550 Error When I try to get the size of a file on an FTP

    - by Eric
    I'm trying to use an FtpWebRequest to get the size of a file on a company FTP. Yet whenever I try to get the response an exception is thrown. See the error details in the catch block in the code below. string uri = "ftp://ftp.domain.com/folder/folder/file.xxx"; FtpWebRequest sizeReq = (FtpWebRequest)WebRequest.Create(uri); sizeReq.Method = WebRequestMethods.Ftp.GetFileSize; sizeReq.Credentials = cred; sizeReq.UsePassive = proj.ServerConfig.UsePassive; //true sizeReq.UseBinary = proj.ServerConfig.UseBinary; //true sizeReq.KeepAlive = proj.ServerConfig.KeepAlive; //false long size; try { //Exception thrown here when I try to get the response using (FtpWebResponse fileSizeResponse = (FtpWebResponse)sizeReq.GetResponse()) { size = fileSizeResponse.ContentLength; } } catch(WebException exp) { FtpWebResponse resp = (FtpWebResponse)exp.Response; MessageBox.Show(exp.Message); // "The remote server returned an error: (550) File unavailable (e.g., file not found, no access)." MessageBox.Show(exp.Status.ToString()); //ProtcolError MessageBox.Show(resp.StatusCode.ToString()); // ActionNotTakenFileUnavailable MessageBox.Show(resp.StatusDescription.ToString()); //"550 SIZE: Operation not permitted\r\n" } This code does work, however, when connected to my personal FTP. The StatusDescription of the response says that the operation is "not permitted". Could it be that my office FTP just wont allow for the querying of a file size? I've also tried listing the directory details, which will return the size, and have noticed that my office FTP reports the directory details in a different format then my personal FTP. Maybe this is the problem? //work ftp ListDirectoryDetails -rw-r--r-- 1 (?) user 12345 Nov 16 20:28 some file name.xxx //personal ftp ListDirectoryDetails -rw-r--r-- 1 user user 12345 Mar 13 some file name.xxx From reading this blog post I think that my personal ftp is returning a Unix formatted response, but my work is returning a windows formatted response. Maybe this is unrelated but I thought I'd mention it.

  • Performance of "returning" from a Try block

    - by Mystagogue
    Exception handling on Windows boxes (at least for C++) takes a performance hit if you exit a try block prematurely (such as executing a return statement) the same as if an exception were thrown. But what about C#? Is there a performance hit for returning prematuraly from a try block, whether through a return statement or break statement?

  • sizeof abuse : get the size of a const table

    - by shodanex
    When declaring a const table, it is possible to get the size of the table using sizeof. However, once you stop using the symbol name, it does not work anymore. is there a way to have the following program output the correct size for table A, instead of 0 ? #include <stdio.h> struct mystruct { int a; short b; }; const struct mystruct tableA[] ={ { .a = 1, .b = 2, }, { .a = 2, .b = 2, }, { .a = 3, .b = 2, }, }; const struct mystruct tableB[] ={ { .a = 1, .b = 2, }, { .a = 2, .b = 2, }, }; int main(int argc, char * argv[]) { int tbl_sz; const struct mystruct * table; table = tableA; tbl_sz = sizeof(table)/sizeof(struct mystruct); printf("size of table A : %d\n", tbl_sz); table = tableB; tbl_sz = sizeof(tableB)/sizeof(struct mystruct); printf("size of table B : %d\n", tbl_sz); return 0; } Output is : size of table A : 0 size of table B : 2

  • make a div block share a line?

    - by acidzombie24
    -edit- example: http://jsfiddle.net/AXCap/ i want the three links to be on the same line but the 3rd must be a block to take up remaining space in the li so that it is clickable. I tried a number of things and the example linked above is my closest result. How do i make the 3rd link share the same line and a block so the resut of the line is clickable? I tried float left and that does not allow the third link to take up remaining space.

  • function taking in an input image and different kernel size

    - by drifterOcean19
    I have this filtering function that takes an input image, performs convolution using a given kernel, and returns the resulting image. However, I can't seem to work it out how to make it takes different kernel sizes.For example instead of pre-defined 3x3 kernel as below in the code, it could instead take 5x5 or 7x7. and then the user could input the type of kernel/filter they want(Depending on the intended effect). I can't seem to put my head around it. i'm quite new to matlab. function [newImg] = kernelFunc(imgB) img=imread(imgB); figure,imshow(img); img2=zeros(size(img)+2); newImg=zeros(size(img)); for rgb=1:3 for x=1:size(img,1) for y=1:size(img,2) img2(x+1,y+1,rgb)=img(x,y,rgb); end end end for rgb=1:3 for i= 1:size(img2,1)-2 for j=1:size(img2,2)-2 window=zeros(9,1); inc=1; for x=1:3 for y=1:3 window(inc)=img2(i+x-1,j+y-1,rgb); inc=inc+1; end end kernel=[1;2;1;2;4;2;1;2;1]/16; med=window.*kernel; disp(med); med=sum(med); med=floor(med); newImg(i,j,rgb)=med; end end end newImg=uint8(newImg); figure,imshow(newImg); end

  • VB.NET: question about "using" block

    - by Craig Johnston
    Consider the code: On Error Goto ErrorHandler Using sr As StreamReader = New StreamReader(OpenFile) str = sr.ReadToEnd sr.Close() End Using Exit Sub ErrorHandler: If there is an error inside the Using block how do you clean up the sr object? The sr object is not in scope in ErrHandler so sr.Close() cannot be called. Does the Using block cleanup any resources automatically even if there is an error?

  • How to adjust font size with Cufon?

    - by user77413
    I am using a condensed font in Cufon. When the page loads, my menu is too wide and wraps. Then Cufon replaces the font and it looks fine. To reduce the visual distraction, I want to set the font size smaller and then have Cufon change the font size when it displays. Currently the font size is set by the div containing the menu. Here is the CSS for the menu container: .header_menu_block { display: block; margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px; margin-top: 3px; /*margin-left: 238px; ie 6 can't handle, see margin block below*/ float: left; text-align: left; font-weight: normal; font-size: 14px; color: #FFFFFF; height: 41px; width: 991px; } The Cufon replacement code looks like this: <script type="text/javascript"> Cufon.replace('.header_menu_block_col_menu ', { color: '#ffffff', hover: {color: '#204966'} } ); </script> I've tried setting the CSS font size to 12px and then using the following Cufon code, but it does not work: <script type="text/javascript"> Cufon.replace('.header_menu_block_col_menu ', { color: '#ffffff', hover: {color: '#204966'}, font-size:'14px' } ); </script> Does anyone know how to do this?

  • How to limit TCP writes to particular size and then block untlil the data is read

    - by ustulation
    {Qt 4.7.0 , VS 2010} I have a Server written in Qt and a 3rd party client executable. Qt based server uses QTcpServer and QTcpSocket facilities (non-blocking). Going through the articles on TCP I understand the following: the original implementation of TCP mentioned the negotiable window size to be a 16-bit value, thus maximum being 65535 bytes. But implementations often used the RFC window-scale-extension that allows the sliding window size to be scalable by bit-shifting to yield a maximum of 1 gigabyte. This is implementation defined. This could have resulted in majorly different window sizes on receiver and sender end as the server uses Qt facilities without hardcoding any window size limit. Client 1st asks for all information it can based on the previous messages from the server before handling the new (accumulating) incoming messages. So at some point Server receives a lot of messages each asking for data of several MB's. This the server processes and puts it into the sender buffer. Client however is unable to handle the messages at the same pace and it seems that client’s receiver buffer is far smaller (65535 bytes maybe) than sender’s transmit window size. The messages thus get accumulated at sender’s end until the sender’s buffer is full too after which the TCP writes on sender would block. This however does not happen as sender buffer is much larger. Hence this manifests as increase in memory consumption on the sender’s end. To prevent this from happening, I used Qt’s socket’s waitForBytesWritten() with timeout set to -1 for infinite waiting period. This as I see from the behaviour blocks the thread writing TCP data until the data has actually been sensed by the receiver’s window (which will happen when earlier messages have been processed by the client at application level). This has caused memory consumption at Server end to be almost negligible. is there a better alternative to this (in Qt) if i want to restrict the memory consumption at server end to say x MB's? Also please point out if any of my understandings is incorrect.

  • Dynamic Cocoon Block list

    - by Crischan
    Hi, I have a Cocoon 2.2 based application which uses blocks for different tasks and one block for shared pipeline fragments. All blocks are mounted within an Cocoon webapp. Now I would like to have an block which generates an overview of all other mounted blocks. I probably will have to use Java code - which is fine - but I am kinda lost where to start. Can anyone point me the right direction?

  • Changing the block size of a dfs file in Hadoop

    - by Sam
    I found that my map tasks is currently inefficient when parsing one particular set of files (total 2 TB). I'd like to change the block size of files in the Hadoop dfs (from 64MB to 128 MB). I can't find how to do it in the documentation for only one set of files and not the entire cluster, does anyone know the command that would change the block size when I upload it (ie copy from local to the dfs)? Thanks!

  • Getting around url block for game

    - by Josh T
    So I play a game called Battlefield Play4Free (www.battlefield.play4free.com). Its essentially a giant browser plugin. The admin on my computer used to have the url battlefield.play4free.com/en/playnow.html blocked which only blocked the page that launches the game (i found a way to launch the game without going to that page and the game worked fine). Now it blocks battlefield.play4free.com which thus blocks all subpages. However, I have found that if I change it to an https and go to https://battlefield.play4free.com/en/login.html to login and then https://battlefield.play4free.com/en/playnow.html I can launch the game. However, when the game launches the borders and everything show but the window content is just a giant blockpage (the same one that shows up when I go to battlefield.play4free.com in the browser) and the blocked page is battlefield.play4free.com (main page). Is there any way I can get around this? I need a way to make the game access the server without going through the browser i.e. make the game use a proxy to get the data or somehow get past the besafe block. I was thinking perhaps you could get around it if you could get the game to make a direct request to the server and not through the url/browser, I know this works because I have a torrenting app that even tho torrent sites are blocked in the browser, the app makes a direct request and thus is not blocked. By the way, the program that blocks everything is besafe or besecure something like that. I do have access to an admin account (on the computer not the besafe program) as well as router access and pretty much anything else. Thanks so much!

  • Opening and Testing Ports on Modem > Router Connection

    - by JakeTheSnake
    Working off of my last question, I can access my server's FTP over the LAN but not over the internet. I'm using Filezilla on port 666. My router/modem configuration is as such (similar to other post): 1) Modem connects to WAN 2) WAN port on modem connects to LAN port on Router 3) Modem internal IP address is 192.168.0.254 4) Router internal IP address is 192.168.0.1 5) Modem has DHCP turned OFF 6) Router has DHCP turned ON 7) Router is running Tomato firmware and it's set as 'Router' (not 'Gateway') 8) The internet is working (just had to say that) I've set up port forwarding both on the modem and router - both route port 666 to the IP address of 192.168.0.3 (TCP); that is the IP address of the server which has FileZilla running. I don't know if that's hindering anything but I've also tried it with just the modem and just the router...same result. I've also tried setting the server to be DMZ (both on router and modem). Neither router nor modem have anything in their logs about denying inbound traffic on port 666 so my ability to troubleshoot stops there. I've tried contacting my ISP (Telus, running on mobility plan...it's a "Smart" Hub) but they weren't much help. They said they only block port 25 and 80 and maybe a few others, but not most ports. I test whether or not the port is open by going to canyouseeme.org - I don't know whether or not that would produce a 'connection refused' result just based on the fact that the FTP requires a login...I'm not well versed on this matter. FWIW, sometimes I get a 'connection refused' error on canyouseeme.org but mostly it's 'connection timed out'. I don't know what else to do at this point.

  • Nginx Server Block Port 8081 Path to Root Folder

    - by Pamela
    I'm trying to password protect all of port 8081 on my Nginx server. The only thing this port is used for is PhpMyAdmin. When I navigate to https://www.example.com:8081, I successfully get the default Nginx welcome page. However, when I try navigating to the PhpMyAdmin directory, https://www.example.com:8081/phpmyadmin, I get a "404 Not Found" page. Permission for my htpasswd file is set to 644. Here is the code for my server block: server { listen 8081; server_name example.com www.example.com; root /usr/share/phpmyadmin; auth_basic "Restricted Area"; auth_basic_user_file htpasswd; } I have also tried entirely commenting out #root /usr/share/phpmyadmin; However, it doesn't make any difference. Is my problem confined to using the incorrect root path? If so, how can I find the root path for PhpMyAdmin? If it makes any difference, I'm using Ubuntu 14.04.1 LTS with Nginx 1.4.6 and ISPConfig 3.0.5.4p3.

  • best-practices to block social sites

    - by adopilot
    In our company we have around 100 workstation with internet access, And day by day situation getting more worst and worst from perspective of using internet access for the purpose of doing private jobs, and wasting time on social sites. Open hearted I am not for blocking sites like Facebook, Youtube, and others similar but day by day my colleagues do not finishing his tasks and while I looking at their monitor all time they are ruining IE or Mozilla and chat and things like that. In other way Ill like to block youtube sometime when We have very poor internet access speed, Here is my questions: Do other companies blocking social sites ? Do I need dedicated device for that like hardware firewall, super expensive router Or I can do that whit my existing FreeBSD 6.1 self made router with two lan cards and configured nat to act like router. I was trying do that using ipfw and routerfirewall but without success, My code looks like ipfw add 25 deny tcp from 192.168.0.0/20 to www.facebook.com ipfw add 25 deny udp from 192.168.0.0/20 to www.facebook. ipfw add 25 deny tcp from 192.168.0.0/20 to www.dernek. ipfw add 25 deny udp from 192.168.0.0/20 to www.dernek. ipfw add 25 deny tcp from 192.168.0.0/20 to www.youtube. ipfw add 25 deny udp from 192.168.0.0/20 to www.youtube.com
