Networking :: Active FTP Using Raw FTP Commands / Turn Off Passive Mode Using It?

Apr 1, 2009

Can anybody have an idea of an ftp client code using raw ftp commands.

Can anybody tell me how to turn off passive mode using raw ftp commands.
PASV is the command which turns on passive mode but there is no such alternative of active mode.
I have already tried using pasv_enable=NO in vsftpd.conf but that is not working.

Networking :: Use FTP Client (for Example Ncftp) To Connect In Active Mode?

Nov 19, 2010

I want to use FTP client (for example ncftp) to connect in active mode. I have firewall (iptables) on my laptop and most of time I am behind rooter. With outgoing packets and with passive mode all is working fine.But some sites accept only active mode.I could open some port range in firewall and in rooter for active data packets, but I don't know how to solve security issues.So how should I correctly manage active ftp connection?

How can I set data port range when opening active connection with ncftp (or maybe another ftp client)?How can I limit that incoming connections to that ports range is accepted only by ncftp or else dropped?

General :: SSH Tunnel Commands To List Active/disconnect?

Apr 1, 2010

I've just started experimenting with SSH tunnels. I wanted a way to connect to MySQL on our website VPS but wanted the connection encrypted rather than just using PHP's mysql_connect() function and connecting to the remote IP. This seems to be working great. I'm also looking into autossh to make sure that the tunnel gets reconnected when it there a command/utility that can list the currently active SSH tunnels? Be great if there was a way of terminating an active tunnel through a command as well. Or is it a case of manually digging through the process list and killing the specific PID like I have been?

Networking :: Pure-ftpd Passive Transfers Not Working?

Jun 4, 2010

I have a dns-323 linux device that's running pure-ftpd with SSL/TLS authentication. Pure-ftpd is sitting behind a linksys router with IP Pure-ftpd is configured for port 8021 and passive port range 55562-55663. The linksys router is configure to forward port 8021 and the passive port range to

From outside my network I can connect to the ftp server using the WAN address of the router. I'm using filezilla 2.2.32 as my client and I choose FTP w/ explicit TLS (no other option will connect). The client will authenticate successfully with pure-ftpd but once it sets up the passive data connection and tries to do a LIST of the root directory, there's a timeout. I'm assuming this is because the passive data connection is not working. In pure-ftpd, I tried changing the passive address that it reports, to be the WAN address of the router, but it did not make a difference. I included the log from filezilla below.

Ubuntu Multimedia :: Can't Turn OFF Suspend Mode?

Feb 26, 2011

Disclaimer: I have very little linux desktop experience...I've only used command line stuff for work in my previous life. I am joyfully coming off of a long addiction to MS but am having a bit of a hard time adjusting.

ISSUE: I can't seem to figure out how to turn off suspend mode. I have turned every setting I could find in the power management to "do nothing" and I have turned off all of my power mgmt options in the system bios. A "friend" suggested I remove HAL...which caused me to lose my secondary internal HD and all of my usb devices...and the issue persisted. Every 20 minutes of no action the screen blanks and my monitor goes into standby mode which is making watching movies in bed a less than relaxing experience.

Some background that may or may not be useful: I installed kubunutu 10.04 (2.6.32-28-generic) from cd on a fresh HD. Initially I had issues with the wireless network and alsa/pulse sound. I worked through those through much trial and error but the suspend issue persists. I've uninstalled and re-installed lots of packages I probably shouldn't have been messing with and would really like to avoid a reinstall as this seems to be the final fix I need to get things running the way I want them.

Fedora Security :: Turn Off Ordered Data Mode?

Dec 8, 2009

I am currently trying to turn off ordered data mode for ext3 filesystem. I want to shred some files and apparently this won't work with journaling on.

I can't seem to find any good explanations of what exactly "ordered data" means in terms of data recovery/security...or at least none that are written in simple n00b terms. It is all written in terms of disk crashes and whether old data will mix in with the new. It doesn't say whether one's cousin will be able to poke around and find some thought-it-was-deleted porno if he's on the computer.

Can someone step me through the process of turning this off using tune2fs? (if that is the best way to do it!) Do I have to revert to ext2? Can I turn it back on later? Will I lose data (for example, does the drive need to be reformated?) once this change is made? And how does one find, read, and delete/shred the journal itself? Is "ordered data" even a real problem for data recovery?

General :: Turn Off Monitor (Energy Saving) While In Text Console Mode

Nov 3, 2010

How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.

The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?

Ubuntu Networking :: High Throuput Mode Aka 11n Aka 801.11n Mode On Airlink101 AWLL6075?

Sep 21, 2010

I ordered this USB 802.11n dongle for about $10 and am having problems.I found a firmware related bug (Bug #595455) that keeps it from working out of the box and got around that. I put the right firmware file in the right place and CAN CONNECT TO B or G Access Points.hen I put my AP in N-Only mode, I can see the network, but cannot associate. With the AP in mixed mode I can Associate using G.The most interesting thing I found was something that had very
few google hits (like 4). In the dmesg output after associating I see the message:

Successfully associated, ht not enabled(0, 1)The most interesting thing about this is the (0, 1) at the end.I don't know what that means but it seems like a clue as to what the problem is.This device uses the realtek chipset 8191S, there are conflicting reports on this, but all the reported possibilities seem to use the same driver from realtek (rtl8712_8188_8191_8192SU_usb_linux_v2.6.0006.2010 0625).Here is some random info:

Dmesg output:

Ubuntu Servers :: MySQL - Setup An Active / Active Load Balanced And High Available?

Mar 11, 2011

how to setup an Active/Active Load Balanced and High Available (If one of the nodes is down the system still runs) MySQL cluster. I have found quite a few howto's but I have some things unclear in my mind. I found a few solutions like this one: [URL] or this: [URK] Those are using two or four MySQL nodes, two Load Balancers to avoid a single point of failure but only one MySQL cluster management server. What happens if the MySQL cluster management fails?

I have also found a "MySQL Master-Master Circular Replication" technique but from what I read, with this option there is a chance that conflicts will arise if node A and node B both insert an auto-incrementing key on the same table.

Hardware :: Get A 2nd Display For A PCMIG 1.0 Passive Backplane With An Advantech 6010 CPU?

May 2, 2011

Need to get a 2nd display for a PCMIG 1.0 passive backplane with an Advantech 6010 CPU [onboard video works fine], but NO PCI card will come up as the 2nd display! Tried 11 cards and most leave the cursor at the top corner when doing xorg-configure, but no that's all.

Has anyone gotten a 2nd display to work on a passive backplane system? Tried some newer cards, but they don't even allow the system to POST - perhaps because they are PCI 3.0 and the backplane is PCI 2.0 or 2.1?

Networking :: IP Address Active But Not Seen?

Sep 20, 2010

I have a 2 node Oracle cluster running on RHEL 5.4. One server went down the other day, and then restarted. Virtual IP address switched to the other node as it should, but did not switch back where the failed node came up - problem is the ip address is still on node 2, but I cannot see it or down the interface as it does not show up with ifconfig -a. I would expect to see it on eth0:2 but only eth0:1 is showing up with the correct vip for the node. ifconfig -a on node 1 shows n vip configured. I can telnet to this ip address and login, so know it is still on node 2, so why can't ifconfig -a show it, which interface is it on, and how do I remove it so I can get it back on node 1
