  • Administer postgres from PGAdmin on remote mac using ssh tunnel

    - 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. I've created an ssh tunnel - macbook:~postgres$ ssh -L 5423:localhost:5432 [email protected] And I can connect using psql on the macbook as expected - macbook:~ me$ psql -U postgres -p 5423 -h localhost ... postgres=# In the 'New Server Registration' window on PGAdminIII I'm entering the following credentials - Name - MyServer Host - localhost Port - 5423 Maintenance DB - postgres Username - postgres Password - <remote_postgres_password> However the connection fails - Error connecting to the server: FATAL: password authentication failed for user "postgres" Not sure what's going on here, these seem to be the same credentials I've used for psql.

  • 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?

  • 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?

  • 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?

  • 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! :)

  • SATA Backward compatibility? [closed]

    - by Fladur
    Possible Duplicate: Can I connect a SATA-II hard drive to a SATA-I connection? Hello everyone One of my system is really old, but I still use it, right now, the HDD is and old IDE drive that is starting to fail (I got to many damaged sectors) and I'm planing to replace it. The motherboard supports Serial ATA 1 and I have a real nice offer on a SATA 2 drive, can I use that drive on a SATA 1 interface (obviously with reduced speed) just like a USB 2.0 device on a 1.0 port? Thanks in advance.

  • 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.

    Some friends gave me their old HandyCam and a bunch of tapes asking me to put them on a DVD. The model is Sony DCR-TVR103 and it records onto Hi8 digital tapes. It has a firewire port also.

Thank you.

  • 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?

  • 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.

  • 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.

  • 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?

  • 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?

  • 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.

  • Why is my FTP output file blank?

    - by Nathan Long
    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

  • 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?

  • not able to mount media to ESX 4.0

    - by jack8138
    Hi, I have ESX 4.0 running on NEC Express 5800 R-120a model. I have 2 VMs running windows XP. I am not able to mount any media to it. When I try connecting the local media to the VM, the error message comes mentioning "a connection to the host could not be established.: I have checked and there is no network issue. ESX is accessible fine. Any help would be greatly appreciated. Besides, I have opened almost all the ports in the firewall just to make sure there is no port conflict.

  • 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

  • Security question pertaining web application deployment

    - by orokusaki
    I am about to deploy a web application (in a couple months) with the following set-up (perhaps anyways): Ubuntu Lucid Lynx with: IP Tables firewall (white-list style with only 3 ports open) Custom SSH port (like 31847 or something) No "root" SSH access Long, random username (not just "admin" or something) with a long password (65 chars) PostgreSQL which only listens to localhost 256 bit SSL Cert Reverse proxy from NGINX to my application server (UWSGI) Assume that my colo is secure (Physical access isn't my concern for the time being) Application-level security (SQL injection, XSS, Directory Traversal, CSRF, etc) Perhaps IP masquerading (but I don't really understand this yet) Does this sound like a secure setup? I hear about people's web apps getting hacked all the time, and part of me thinks, "maybe they're just neglecting something", but the other part of me thinks, "maybe there's nothing you can do to protect your server, and those things are just measures to make it a little harder for script kiddies to get in". If I told you all of this, gave you my IP address, and told you what ports were available, would it be possible for you to get in (assuming you have a penetration testing tool), or is this really protected well.

  • What could cause my LAN Pings be greater than 100ms?

    - by James Holland
    I have 2 servers (Both: Windows Server 2008, Dual Xeon 2.8Ghz, 32GB RAM, 8 x 15k SAS Drives). One of them is a DC / Web server / Exchange Server, the other is a SQL Server (2008). I have a 48 port Netgear GS748T Gigabit switch. When I ping from server to server, I get ping times <1ms, great, but when I ping from a PC, I get varying pings from the occasional <1ms to 500ms!! If I log into either server and look at Task Manager, CPU usage peaks at 20%, memory usage is 100%, but I am led to believe this is normal as Exchange will just use as much as you have, and release it when requested. Network usage peaks at 1%. I really don't understand how the ping can vary that much. I know I am giving very little info, but this is all I know, I apologise, but can anyone help? In response to question, I have pinged by both IP address and hostname, no difference in ping times.

  • Why did cherokee-admin-launcher crash?

    - by DarenW
    I'm trying out the Cherokee http server on a seemingly fine machine. Following simple set-up instructions, I tried running cherokee-admin-launcher but it printed error messages and hung up. Ctrl-C did not kill it; I had to kill -9 it from another xterm. OTOH, cherokee-admin ran fine (or at least got a lot further). What is the problem with python and cherokee-admin-launcher, and how to fix it? [root@iron rc.d]# cherokee-admin-launcher Checking TCP port 9090 availability..
