• How to disable passive mode in linux ftp command

  - by nute

  I am using the "ftp" command of linux to send data to a 3rd party provider. This company states that we need to "Disable passive mode in your FTP client", and I confirm it doesn't work in passive mode. However, when I googled the linux command, I see that the "-p" flag is "the default now for all clients (ftp and pftp) due to security concerns using the PORT transfer mode. The flag is kept for compatibility only and has no effect anymore." How do I disable passive mode then? And, is it that bad?

• Linux router and firewall with IP accounting

  - by Andrew

  I'm working on a project to replace my organisation's aging Slackware gateway/router/firewall machine in our colo rack. Previously we used rc.firewall but we are now looking for something more modern and easily configurable. The requirements are: Act as a gateway router & firewall Port forwarding to a Terminal Server in the colo IP/traffic accounting, preferably accessible via SNMP (already using cacti for other servers) Possibility of acting as a PPTP server & routing these connections Is not an out-of-the-box Cisco product (don't have the finances or support to maintain it) I'd prefer to use Ubuntu or some other Debian-based distro but something that integrates everything we're looking for is certainly an option if it offers all the desired features and is easy to configure. Is there a simple set of packages that will provide me with the Firewall & Accounting features, or am I best served with a custom-built distro / other solution?

  - by Aidan Ewen

  I've got PostgreSQL installed on a Ubuntu server and I'm trying to connect to that server using PGAdmin on a remote macbook.

• Windows 7 - swap file on a USB disk? [closed]

  - by Sara Cohen

  Possible Duplicate: How to move the page file to another physical disk location Windows 7 I was given temporarily a PC, running Windows 7 Ultimate. The problem is it's hard drive is full, there are like 250 MB free. The swap file is set to none. It has 4 GB RAM. When I load a few tabs in Chrome or IE and start a game it runs out of memory. I already emptied Recycle Bin, %temp%, etc. Deleting/moving user files or adding RAM is not an option. Now I have a USB 3 7200 RPM drive, it's connected to a USB 3 port and is really fast. Is there a way to create a swap file on that drive?

• Why Mac cannot connect to Iphone?

  - by martin08

  I couldn't always ssh to my iPhone from my Mac. They're both on the same wifi network but sometimes the connection is established, sometimes it failed. From my Mac: $ ssh [email protected] ssh: connect to host 192.168.0.102 port 22: Operation timed out $ ping 192.168.0.102 PING 192.168.0.102 (192.168.0.102): 56 data bytes ping: sendto: No route to host ping: sendto: Host is down ping: sendto: Host is down I enabled SSH on the phone and am sure it can load webpages. So what might be a reason why they cannot connect? Thanks

• Can I set up OpenVPN on two or more machines so that they can each act as client and server?

  - by ianfuture

  The question summarises what I want to achieve. In more detail: I have a Windows XP Pro PC at a work location that I want to be able to access my home Windows XP Pro PC and other home computers from. But I also want to be able to connect to the work PC from home. I think the term generally used is a "mesh" network. Can I do this with OpenVPN ? If so how would I do it? What are the most important things to remember to do? EDIT: The work Windows XP Pro PC is largely managed by IT Dept, I do have local admin rights to install things. Some settings are disabled. My main concern was firewalls and port forwarding on the work PC. Any suggestions?

• Configure VPN to access remote LAN network on Windows7

  - by PiotrK

  Situation: I have two Windows7 machines (PC and laptop). I've set PC as VPN server and laptop as VPN client using default built-in W7 network tools. I've disabled use default gateway in remote network on client machine, so client don't try to route all communication through VPN. I've routed port 1723 (TCP/UDP) on NAT to my server and enabled IPSec/PPTP/L2TP passthrough I've put my laptop in indepedent network (basically I've connected it via 3G network), connected to VPN server and checked ipconfig /all I've get: IP Address: 192.168.1.101 Mask: 255.255.255.255 Gateway: (none) LAN mask in server LAN network is 255.255.255.0 - I am surely missing something obvious, but Google doesn't give me any good advices; How can I access local LAN network from remote VPN client? How can I access local shared documents?

• self-issued exchange certificate for dyndns-url

  - by Sam

  I've got an exchange server behind behind a port to address translation firewall. The server is reachable from the internet using a dyndns-url. Now I want to sync windows phones to exchange mailboxes. To achieve this, I need to install the exchange certificate on the windows phone (send it to the phone by mail, double click). So far so good. But, as far as I can see this does only work if the certificate on my exchange server matches the dyndns-url? So I'd like to know: how do I create a self signed certificate for my dyndns-url and install it on exchange?

• Firefox https problem with localhost

  - by vnuk

  I administer half a dozen servers with (among other things) Webmin. I connect to Webmin via ssh tunnel to port 10000. All of my Webmins run in https mode. Firefox from version 3.6.6. refuses to load my https://localhost:10000 pages claiming SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) Why is this problem NOW? It was working fine (annoying with certificate errors, but working) but now it is not working at all. I must have Google Chrome installed so I can connect to Webin.

• Apache 2.2.16 + PHP 5.2.14 sometimes causes Apache to not stop properly

  - by ZiggyTheHamster

  Sometimes, Apache decides not to shut down nicely. killall apache2 or kill -9 (apache2 PID here) shuts it down so that it can actually start back up without the port being in use. Other posts seem to indicate that PHP 5.2 might have issues hanging up Apache. I'm using the worker MPM on an x86_64 Gentoo Linux system if that helps. Any other things I should consider hanging up Apache besides PHP? Should I be stopping Apache with /etc/init.d/apache2 gracefulstop instead of /etc/init.d/apache2 stop?

• How do you change your Airport or Ethernet MAC address in Mac OS X 10.6?

  - by Dave Gallagher

  I have a MacBook Pro and would like to set a custom MAC address for either my Airport WiFi card, or Ethernet port. In older versions of Mac OS X, you could do it like this: $ sudo ifconfig en0 ether 00:11:22:33:44:55 // Ethernet $ sudo ifconfig en1 lladdr AA:BB:CC:DD:EE:FF // Airport For it to work on Airport, you'd have to power it on (e.g. $ sudo ifconfig en1 up), ensure it's not connected to any wireless network, and execute the command. I'm aware such a change won't propagate across reboots. Unfortunately, this doesn't work on Mac OS X 10.6.6 anymore. Apple appears to have removed the functionality (the command fails silently). Does anyone have any idea how to do it? Thanks for any help you can offer! :)

• Straight cable or cross over cable?

  - by om sai

  I have pppoe internet connection. My ISP provides connections like this: ISP->media converter(fiber)->8 port switch(TP Link TL-SF1008D)->to individual internet connection account holders (like me) Now the connection between the media converter and the switch is done using 4 pair cross over cat5 cable and I would like to connect the cable running from the switch to the router and through router to my PC. So what type of cable should I use to make the connection between the switch and the router (straight thru cable or cross over cable)? The point I am trying to make is I am able to connect to the internet using straight through cable between the switch and my PC but when I connect the same cable between the switch and the router and from router to my PC I am not able to connect to the internet. Also, if I am using the 2 pair cable (instead of 4) between the switch and the router I am able to connect to the internet but same is not true in case of 4 pair cat5 cable.

• Reputable web based ssh client? [closed]

  - by Doug T.

  I'm connected to a coffee shop's wireless network right now, and I suspected I'd be able to use my laptop and ssh somewhere. Unlucky me they seem to be blocking everything but web traffic (my testing seems to show everything but port 80 is working, can't ping, ftp, etc). I googled "web based ssh clients" however I have reservations about entering my login credentials on any Joe Schmoe's web app. I was wondering if anyone has had any experience with any reputable web based ssh clients? If so could you please point me at one that I could trust?

• Open source alternative for Canonical Landscape? [on hold]

  - by netvope

  From Canonical: Landscape is an easy-to-use systems management and monitoring service that enables you to manage multiple Ubuntu machines as easily as one through a simple Web-based interface. However, Landscape is not free. The RedHat counterpart Satellite has a free version called Spacewalk, but it doesn't work on Ubuntu. (There is an attempt to port Spacewalk to Debian, but it doesn't look like it's stable yet.) Are there any open source alternative to Landscape? Better yet, are there any Spacewalk-like software that works for both RedHat-based and Debian-based systems?

• How can I monitor network traffic in an all Mac home network?

  - by raiglstorfer

  I have an all Mac network consisting of an Airport Extreme, 1 MacPro, 1 Mac Mini, 2 MackBook Pros, 2 iPads, and 2 iPhones. The Mac Pro is connected directly to the Airport Extreme via Cat5 and the rest is all running via Wireless. Lately I've been getting prompted by Google to enter Capchas frequently. The message states that I might have software running on my network I'm not aware of. My wireless router is password protected using WPA2 Personal and I frequently change my password so I don't think someone is using the network from outside (but I've no way to confirm this). I'm looking for a relatively cheap (preferably open source) solution that would enable me to monitor and profile the network usage by machine and port. Can someone recommend a solution?

• Is there a free-embedded SSH solution ?

  - by ereOn

  Hi, I'm working for an important company which has some severe network policies. I'd like to connect from my work, to my home linux server (mainly because it allows me to monitor my home-automated installation, but that's off-topic) but of course, any ssh connection (tcp port 22) to an external site is blocked. While I understand why this is done (to avoid ssh tunnels I guess), I really need to have some access to my box. (Well, "need" might be exagerated, but that would be nice ;) Do you know any web-based solution that I could install on my home linux server that would give me some pseudo-terminal (served using https) embedded in a web page ? I'm not necessarily looking for something graphical: a simple web-embedded ssh console would do the trick. Or do you guys see any other solution that wouldn't compromise network security ? Thank you very much for your solutions/advices.

• Configuring Server with no monitor

  - by Scandalist

  Sitting in front of me is an HP DL 380 Generation 4 with no monitor. I'd like to install an OS on the thing but for reasons obvious, I can't. I got excited when I found the ILO port on the back but unless you have a subscription it has limited functionality. I was thinking maybe there was some software out there that booted into some kind of remote access server? When I tested it with a monitor (A friends) I set the BIOS to boot from USB so anything I can load onto a stick should boot. Ideas? Hacks?

• Does Juniper Networks provide keyloggers with their software?

  - by orokusaki

  I noticed that I had a "USB Mass Storage Device" plugged in when there wasn't in fact anything plugged in to any USB port. I turned it off via Windows (XP), but it's quite concerning. This was after installing Juniper Networks' software for VPN access to an IT guy's stuff. I also notice there is a service called "dsNcService.exe" which apparently is sending information over the internet (even when I'm not in VPN access). The process restarts itself when I end it. Should I be worried that this software is tracking my keystrokes and broadcasting them to my IT guy?

• Server 2008 Web Edition IIS6 SMTP conflict

  - by user219313

  I'm using IIS6 Manager to setup the SMTP service on Windows Server 2008 Web Edition. There seems to be a conflict (port 25?) which means that I cannot start and stop the Default SMTP server within IIS6. I can start and stop it with the services.msc snap in and this is reflected in state of the SMTP server in IIS6 manager. I'm worried that none of the settings I want to get at within IIS6 (logging, authentication etc..) are having any effect. None of these settings are available within IIS7 in Web Edition.

• Are there any negative impact running all services on a single static IP?

  - by Jake

  I need to setup a VPN trunk (with remote branch office location), Video Conference and Web Server on-premise in the office. I am used to ISP providing blocks of 8 or 16 IPs. But I have a new ISP which says they only can provide a single IP. Are there any issues with running all services on a single IP? I don't think this has any thing to do with bandwidth..? I'm not using SSL certificates... I can do port forwarding to different machines... What else...? Disclaimer: I am a programmer by training. Sorry for noob question.

• How do you enable syslogd to accept incoming connections on Snow Leopard from remote loggers?

  - by Emmel

  How do I get syslogd to accept incoming connections from remote hosts on Snow Leopard? I'd like to centralize logging such that various devices and systems send logs to Snow Leopard's syslogd, which normally hangs out on UDP 514. However, I'm unable to get them to successfully be accepted by good ole syslogd. I tcpdumped on the Snow Leopard box to verify that packets are being spouted to port 514 -- they are. I checked that syslogd is listening on 514 -- it's not. Googling around told me that, on older versions of OSX (don't you love the way things change so rapidly on OSX), one just had to add a flag to the syslogd daemon to allow remote; one did this in com.apple.syslogd.plist. However the syslogd daemon has no flags (at least in its man page) that suggests any remote anything. What's the solution to this? Secondary, less import but relevant question: What's 'newsyslog'? I see a plist file but it's not running (apparently). Thanks

• Why is my FTP output file blank?

  From the Windows command prompt, I have FTPd to a Windows web server. I can get a file, and I can see a directory listing with dir, but I want to save that list locally. I tried dir > c:\somefile.txt, and the file is created, but it's blank. Same thing if I do ls > c:\somefile.txt. The result is the same when I FTP from a Linux box. FTP sends back the following: 200 PORT command successful 150 Opening ASCII mode data connection for /bin/ls 226 Transfer complete
