150 Opening Ascii Mode Data Connection For /bin/ls

question Anybody can answer The best answers are voted up and rise to the top FTP hangs on: 150 Opening ASCII mode data connection up vote 8 down vote favorite 3 I am setting up an FTP server on my Windows 2008 ftp 150 opening ascii mode data connection server (R2). Everything appears to be installed correctly but I am having trouble using an FTP Client to login to my FTP server. I can remote desktop on to the server and through DOS commands I can login rather easily. But if I issue a command like "DIR", it hangs with: 150 Opening ASCII mode data connection. Everything I have researched and read points to Firewall ports and/or Passive/Active mode settings. Here is what bothers me...if I use DOS FTP commands, I can login change ftp to passive mode and use the "DIR" command only if I use "localhost" as my address. If I specify my full FTP URL, I get the hanging error. if I specify the "localhost" URL, I do not get the error. This leads me to believe its a Firewall issue, (or even an IIS7 issue?) but I am unsure what ports I need to open? I have ports 20, 21 open on my Windows firewall. I have also opened those ports on my AWS (Amazon) firewall. I believe my FTP client is using some long range port number(s) that are potentially blocked by one of my two firewalls. Ive used Network Monitoring tools to try and see what ports it is calling but I cant figure that out.

So if your "AWS firewall" is not doing protocol inspection on this channel there is no way he will know which ports it has to dynamically open to allow the traffic flow (and close once those ports are not longer used). IMHO using network monitoring to discover which ports are being used is not worth the effort bec

Ftp Hangs During File Transfer

can't use the command-line FTP.EXE utility that ships with Windows over the Internet. With all of this in mind, I thought that I would put together a quick blog that explains Active http://serverfault.com/questions/244973/ftp-hangs-on-150-opening-ascii-mode-data-connection and Passive FTP connections and why those matter when you are connecting to an FTP server over the Internet. Here is the briefest description that I can think of to describe the different between Active and Passive FTP: When you are using Active FTP, your FTP client determines how your data connections will work. When you are using Passive FTP, your FTP server determines how your https://blogs.msdn.microsoft.com/robert_mcmurray/2013/05/24/a-quick-discussion-of-active-and-passive-ftp-connections/ data connections will work. That sums up the whole concept into two bullet points. Unfortunately, neither of those bullet points are the least bit significant to you if you don't understand what they actually mean, so I will describe them in detail below. How Active FTP Works The following output shows the communication between an FTP client and FTP server using Active FTP to retrieve a simple directory listing, and I manually color-coded the output so that the client and server's responses would be a little easier to see: OPEN ftp.contoso.com Resolving ftp.contoso.com...

I can log on to the site with my domain user. I can do cd to change directory. But when I do any commands that involvs fetching data from the FTP (dir, get, put) the sessions hangs on: 150 Opening ASCII mode data connection Hangs there until i ctrl-c to stop it. If I wait long enough before I break it I get a connection lost when prompt returns. Commands like CD, pwd, mkdir, rmdir works fine. I have reinstalled the FTP- feature on the server. Please help. 0 Question by:itscdoorway Facebook Twitter LinkedIn Google LVL 7 Best Solution byCGretski What ftp client software are you using. Is it in port or passive mode? If it's in port mode the FTP server will try open a second connection from itself to the client machine to transfer data. This Go to Solution 3 Comments LVL 4 Overall: Level 4 Message Expert Comment by:tomand2010-02-08 Hi, it's is a typical sign of firewall blocking the communication. The FTP uses two types of connection : 1) the control connection which is alway sistablished from client to server (firewalls/NAT have no problems with it usually). So you can login and even change the directory - it is because these actions use already established (control) connection line. 2) the data connection. By default server conencts to client each time when some data should be sent to clinet (or to server from the client). Firewalls on clients tend to block this (because this is potentially dangerous incoming conenction). So you have to either instruct your firewall to allw FTP data connections (i.e. you have to have smart enough firewall which is able to learn from the FTP control connections what conenction will arrive from what server) or you have to instruct your FTP client to use 'passive' mode. In the passive mode client established the data connection to the server (which is firewalls/NAT friendly). Regards D. Toman 0 LVL 7 Overall: Level 7 Windows Server 20
