  • JavaScript-based applications and text browsers

    - by Vi
    How to use complex AJAX applications with a lot of menus and with X.509 authentications in non-GUI mode with simple browsers? For example, I can login to Webmoney from console using links/lynx/link2 (but not w3m), entering captcha (using aaxine) and do operations there, but can't login not using X.509 certificate (even if I try to separate SSL part using "socat tcp-l:... openssl:...:443,cert=extracted_from_firefox.pem") Is there some program that behaves like fully-fledged browser (build DOM/execute JS/Support all features except of actually displaying things), but without GUI and dependencies on GUI libraries?

  • Are EC2 security group changes effective immediately for running instances?

    - by Jonik
    I have an EC2 instance running, and it belongs to a security group. If I add a new allowed connection to that security group through AWS Management Console, should that change be effective immediately? Or perhaps only after restart of the instance? In my case, I'm trying to allow access to PostgreSQL's default port (tcp 5432 5432 0.0.0.0/0), and I'm not sure if it's the EC2 firewall or PostgreSQL's settings that are refusing the connection.

  • Authentication between web server and sql server

    - by thirster42
    So, we're restructuring out development environment. We've installed SQL Server onto it's own server, and we are publishing our internal web applications onto a seperate web server. However, the problem is that for some reason the authentication of the user between the web server and sql server gets lost, resulting in the Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON' error. Where do i start troubleshooting? SQL Server is set up for TCP and remote connections.

  • outbound ftp on server 2008 r2 stalls

    - by Scott Kramer
    the built in command line ftp client in server 2008 does not support passive mode so I've used these commands to allow outbound ftp (it stalls without this) 1) Open port 21 on the firewall netsh advfirewall firewall add rule name="FTP (no SSL)" action=allow protocol=TCP dir=in localport=21 2) Activate firewall application filter for FTP (aka Stateful FTP) that will dynamically open ports for data connections netsh advfirewall set global StatefulFtp enable however in server 2008 r2, these commands seem to work, but it does not affect the outbound ftp, it stalls I do not want to use an alt client

  • Connect to remote MySQL using proxy

    - by hypeflow
    I'm trying to connect to a remote MySQL server (with TCP access limited to a specific IP) using port forwarding via SSH, but still haven't figured out how to do it. Here's what I intend to do: Local[A] ---> Proxy[B] ---> Remote MySQL[C] [A] Local machine with Windows [B] CentOS machine with IP 123.123.123.1 (with it's own MySQL running, btw) [C] Remote MySQL server with IP 123.123.123.1 authorized on port 3306 How to achieve this? Thanks in advance.

  • Windows Server 2008 R2 loses ability to connect to network share

    - by JamesB
    I could sure use some help with this one: I've got two Windows Server 2008 R2 x64 Terminal Servers, as well as several 2003 servers (DNS / Wins / AD / DC). On the two 2008 boxes, every now and then they will get in this mode where you can't map a drive to a random server. I say random server because it's not always the same server that you can't map to. Here is a summary of what I can and can't do: net view \\servername Sometimes this works, sometimes it does not. net view \\FQDN This always works. net view \\IPAddress This always works. ping servername Sometimes this works, sometimes it does not. ping FQDN This always works. ping IPAddress This always works. I've been looking all over for a solution to this. It sure seems like Microsoft would have a hotfix by now. The kicker to this is that it sometimes works great, especially after a reboot. It may run for 2 weeks just fine, but all of a sudden it will fail to resolve the remote server name. It will then be this way for a few days, then it might start working again. Also, while it's in the mode of not working, the other servers have no problem getting there. It's just these 2008 R2 Terminal Servers. Setting a static entry in the Hosts file and LMHosts does not make it work. All servers have static IPs and they are registered in DNS and Wins just fine. Here is a long thread on MS Technet of the exact same problem, but they don't have a good solution. Here is their workaround (It was from June of 2010): Good news - a hotfix is in the works and a workaround has been identified: Root cause is that since this is SMB1 all user sessions are on a single TCP connection to the remote server. The first user to initiate a connection to the remote SMB server has their logon-ID added to the structure defining the connection. If that user logs off all subsequent uses of that TCP session fail as the logon-id is no longer valid. As a workaround for now to keep the issue from happening you will want to have the user not logoff the Terminal Server only disconnect their sessions. Any word from anyone out there about a solution? Any help would sure be appreciated. Thanks, James

  • Is it possible to open server ports on TUN devices?

    - by JosephH
    If I make a VPN connection to a server (say myvpn.com; assume this server is not behind any router/firewall) via a TUN device and open a port (say 5555), will someone else be able to connect to me via myvpn.com:5555? If not, is there a tunneling software that does exactly this in a transparent manner? i.e. run any TCP/UDP-based server instance behind a router without NAT using another remote server.

  • How to monitor streaming servers

    - by pcdinh
    Hi all, I have had a bunch of Linux based streaming servers that employed lighttpd web server to provide video streaming via port 80. Recently, our service is very slow. Therefore, I would like to ask if there is a good software package that helps us monitor and record our bandwidth usage, lighttpd established connections, TCP sync connections, disk I/O ... over time. Any suggestions? Regards, Dinh

    - by Bob Kaufman
    Starting around the time I installed the Office 2010 Beta, Whenever I login, Windows tries to open a file named "Bob", coincidentally the first part of my username. Selecting Notepad to open it, and it contains TCP/IP network settings. I've looked for and deleted unrecognized entries in my StartUp folder, in HKLM/.../CurrentVersion/Run and in HKCU/.../CurrentVersion/Run with no luck. Is there any other place I should be looking for errant entries?

  • Maximise network transfer speed of various applications

    - by Alex
    When using nc, scp, wget to transfer files between 2 machines on a dedicated 2Mbps link, I get speeds between 0.5 and 1 Mbps. However, when I use iperf -c 10.0.1.4 -t 20 -P 12 (for example) I can maximise the speed of the link (getting stable 2Mbps). Is there a way to make single stream transfers (such as those done by scp) to utilise all/most of the link? Some kind of tcp settings, or iptables...?

  • Access Derby for CDP Server

    - by Skudd
    I am working on a project that requires accessing the Derby database behind a CDP Backup Server. From what limited research I've been able to complete, I have found that it is possible to access Derby databases over TCP, but I'm at a complete loss for this. I'm looking to connect via PHP eventually, but first I need to know if this is at all possible with an out-of-the-box CDP server. Answers are, as always, appreciated. Thanks!

  • Streaming a large file

    - by Rich
    quick question say i wanted to download a file of considerable size 10gb say and i sent the GET request to a web server to download that file question is, if the client stopped reading the TCP connection, would the entire file still be downloaded, or does it depend on the client sending back an ack or something to the circuit asking for the next packet hope that makes sense This question was originally asked involving the Tor network, but i just want to know how a standard internet connection would handle this Thanks
