• Development on Windows 7; Web server on Linux - How to share Apache web root?

  - by TheKeys

  I've got a LAMP server that I want to use as a local web server. I've got a Windows 7 machine that I want to use as my development machine. The machines will be on the same LAN (or the Windows box will be VPNed into the LAN). My questions is, what is the best way of sharing the web root of the LAMP server so that I can edit the files on the remote Windows 7 machine and how do I go about configuring this on the Linux machine? (Fedora 16) I would like the solution to be as easy to use as possible with preferably no extra steps required to save/edit/upload files from my IDE on my Windows 7 machine. I'm thinking either a Samba or NFS share are the way to go but I'm concerned I'm going to run into issues with permissions and unix/windows file handling. Is one better than ther other for my use case or is there a better alternative solution? I'm currently using Windows 7 Professional which doesn't have NFS support but would upgrade to Ultimate which does have NFS support if it's the best solution.

• How to enable Ipv6 on my ubunutu 11.04 virtual machine

  - by liv2hak

  I have installed 3 VM's on my PC.(Ubuntu 11.04).I want to setup an IPV6 network to review and test some of the IPV6 tools like NDPMonitor.(monitors ICMP messages of Neighbour Discovery Protocol.) IP v6 addresses are as follows. linux_router - fe80::a00:27ff:fed5:f7e9/64 labhack1 - fe80::a00:27ff:fed2:8bd1/64 labhack2 - fe80::a00:27ff:fed7:2f2d/64 The below commands have been run on both linux_router and labhack1. sudo ip r a 2001:468:181:f100::/64 dev eth0 sudo vim /etc/radvd.conf /file looks like below./ interface eth0 { AdvSendAdvert on; /*means that we are sending out advertisments.*/ MinRtrAdvInterval 5; /*these options control how often advertisments are sent*/ MaxRtrAdvInterval 15; /*these are not mandatory but valueable settings.*/ prefix fe80::a00:27ff::/64 { AdvOnLink on; /*Says to the host everyone sharing this prefix is on the sam local link as you.*/ AdvAutonomous on; /*Says to a host: "Use this prefix to autoconfigure your address"*/ }; }; sudo sysctl -w net.ipv6.conf.all.forwarding=1 I try to do a ping6 -I eth0 fe80::a00:27ff:fed5:f7e9 I get Destination unreachable: Address unreachable.I am not sure what I am doing wrong here.I am a beginner at linux administration.Basically I think I am missing whatever is analogous to physically connecting VM's.Any help that would point me in the right direction would be greatly appreciated.

• XP Client for NFS failure dialog on startup, but drive mapping works

  - by Matt Bennett

  I'm mounting an NFS share to some windows machines using the tools that come in the Services for UNIX Administration toolkit. I've set up the User Name Mapping service to use local passwd and group files. I had to manually start the User Name Mapping service, and then created an 'advanced map' from the XP machine's user to a uid that exists in on my NFS server, like so: Windows User: Matt Bennett UNIX Domain: PCNFS UNIX User: mattbennett UID: 10250 Primary: * I can map a network drive without any issues, and it correctly identifies the UID and GID to use, but when I reboot I get this message: "An error occurred while connecting to the NFS server. Make sure that the Client for NFS service has started. If the problem persists make sure Client for NFS service can communicate with User Name Mapping or PCNFS server." After dismissing the dialog, the machine finishes booting and the network drive is there in My Computer with the title "Disconnected Network Drive", but I can open it I can see the network share without a problem, and then it drops the 'disconnected' from its title. It seems like the services are starting in the wrong order or something, so the first attempt to connect fails but subsequent ones work as expected. There don't seem to be any symptoms apart from the dialog box, but obviously something's not quite right. What have I done wrong? Thanks, Matt.

  Hi all, I'm trying to install Redmine under apache. The apache server works on a local network. My apache setup consist on a single virtual host.

• Ubuntu root privs installation issue

  - by Pam

  I am a fairly new Ubuntu user (and Linux user, for that matter) and I just downloaded a program whose installer was a .sh file. Not thinking, I copied the installer to an /opt subdirectory, thinking that I was going to install the application there: sudo cp ~/Downloads/fooInstaller.sh /opt/someDir I can't remember, but I either had to use sudo because /opt required it, or I just used it without thinking, but in any case, I prefixed with sudo. Once in /opt/someDir, I executed the installer again, using sudo: sudo sh fooInstaller.sh The terminal went crazy, and a few seconds later, a graphical install wizard popped up that guided me through the rest of the process. At the end of the wizard I was prompted to launch the program, and I did, and everything was great. Until... I closed the program, and attempted to add it to my Ubuntu "panel" (the icon panel at the top of the screen). The program was installed to /usr/local/foo/theProgram, and so I specified that URL as the command in the custom app launcher. When I open the program through the panel/launcher (at the top of the screen), the program doesn't load or operate correctly. I get a lot of error messages complaining about being denied permissions. I'm assuming that this is a "superuser/installation/privs" issue, and not a problem with the application (hence this post at superuser.com instead of the application's forums), because when I launch the program from the terminal with sudo, it opens and executes perfectly fine, just like it did the first time around after the install wizard finished. I realize I'm probably going to have to uninstall the program completely, and re-install it differently. Finally, my question: After uninstalling, can I avoid all these issue by just running the installer (sh fooInstaller.sh) right out of my Downloads directory, sans the sudo prefix? If not, how do I get the program to install without root privs so that I can add it to my panel/launcher and get it executing correctly? Sorry for the long post but I didn't want to omit any details because, as I'm sure you can tell, I'm not really sure I know what I'm doing. Thanks for any help here!

• Very strange networking problem in all computers in my house

  - by Anthony

  I have three computers in my house: One desktop (wired), and two laptops (wireless). I'm using Cox Communications (yes they suck), and yesterday they had a major outage. I know it was them because I called them up when I started losing connection to the internet. All the computers can connect just fine, but they don't have internet access. It just says "local only". The weird thing is, some of them work occasionally. For the first day my laptop was working perfectly, while all the other computers couldn't connect. Later on in the day it got reversed, and the desktop was the one with internet access. By the second day the problem on Cox's end was fixed, but we still had no access. I called them up and they reset my modem, and did the usual troubleshooting stuff. It never fixed the problem, but we found out that the problem had to do with conflicting IP addresses. My router was a Linksys WRT54G and it was about 5 years old. I figured it might have gotten damaged from the outage since it was so old, and now it's having trouble "fixing itself" and giving out the proper IP addresses. So I bought a new router, a Cisco Linksys E1000. I set everything up, and still the same problem. My computer has access right now (that's how I'm writing this), but no other computers seem to be able to get access. Is there possible damage to the modem? Can someone help me please? Sorry for this being so long.

• Port Forwarding(?) TD-W8961nd

  - by rich

  I have a bit of a weird internet setup. I am connected via a decent WiFi connection (from work) which I pick up using a Buffalo Airstation Wireless-G box. This simply picks up the signal and gives me 4 ethernet ports to connect to. That's all fine and works as it should. I also have a TP LINK TD-W8961nd router which used to be connected to the Airstation via an ethernet cable so I could essentially have WiFi access in my house. To cut a long story short I can't remember how the hell I got it to work and I can't find the notes I scribbled down on how to do it. I'm pretty sure I need to tell the router what ip to pick up the internet connection from and have the local wifi as a seperate network. How the hell I do that I have no idea right now. Can anyone give me some advice on this? If you need more information ask and I will be able to do so. Cheers in advance. edit I'm in work at the moment so I can't give 100% details but I will be able to later on.

• DD-WRT (WRT54G) and (THOMSON TG782) how to put them togather?

  - by FeRtoll

  Ok so let me explain, i bought WRT54G and successfully installed DD-WRT v24-sp1 (07/26/08) mini-special - build 9994. That's all ok no problems with it all normal functioning. And just to add (i don't need wireless, wireless is turned off always) What i want: ISP's router (TG782) from it's INTERNET port(out) cable "which was before in my pc" is connected to WRT54G's INTERNET port and then from WRT54G LAN port 1 to my pc. The problem: How do i connect and setup all? I have tried many times on many different ways but cant get it to work IF THE CABLE FROM TG782 IS CONNECTED TO WRT54G ON INTERNET PORT. If i connect the TG782 to Lan port 1 on WRT54G and my pc to lan port 2 then all works fine after i setup gateway and all. But i want to connect TG782 to Internet port of WRT54G because i need "Access Restrictions" and this only goes through WAN right? please correct me if i am wrong. What i have tried: This is how i have tried to setup all. The TG782 router ip is 192.168.1.1 And WRT54G ip is 192.168.1.30 so in WRT54G control panel i have setup like this: ----WAN Connection Type---- Connection Type: Automatic Configuration - DHCP STP: Disabled ----Router IP---- Local IP Address: 192.168.1.30 Subnet Mask: 255.255.255.0 Gateway: 192.168.1.1 (the TG782) ----Network Address Server Settings (DHCP)---- DHCP Type: DHCP Server Start IP Address: 192.168.1.100 Maximum DHCP Users: 6 And this wont work i probably miss something more, if anyone can help i would be thankfull. Also i have to note that i have tried to set my network adapter on pc to use the gateway of WRT54G and ip 192.168.1.102 In short: i cant get it to work normal only as a switch! Thanks for any help! -------EDIT:------- Here is an image which maybe can help: http://img27.imageshack.us/img27/4227/allin1w.jpg

• Sharepoint Workflow "Failed on Start" only when powershell import script is called from task scheduler

  - by Matt Keller

  I created a simple PowerShell script that takes an XML file in a local directory on our sharepoint server and imports it into a specific SharePoint form library. (Content management enabled library if that makes any difference) This script works flawlessly if i run it from the PowerShell command line manually. I call it like such: ".\script_name.ps1". It completes without error and the item is imported into the form library successfully. The workflow begins on the item and everything is happy dandy. However, i run into issues when i setup a scheduled task using Windows Server 2008 R2's task manager. The task runs the script without error and it does actually import the XML into the form library. I looks perfectly normal just as if i had run the script manually. However, after about 10 or 20 minutes the workflow status for that item changes from "In progress" to "Failed on Start (Retrying)". The scheduled task in question is a basic task and has only one action. (Start a program) The "program/script" box is set to "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" and the "Add arguments" box is set to the path of the actual ps1 script. (C:\scripts\sharepoint_import.ps1) I've tried running the task as various users. I've also tried with and without the "Run with highest privileges" check box. Nothing seems to work. For reference, here is the script i am using to import items into the form library.

• Using npm install as a MS-Windows system account

• How to run a WebPy server on port 8080 using DDNS of dlink router and to access this site from internet?

  - by nuke1010

  I have two major issue with setting up a web server using my dlink DIR-600L router. Issue 1: I run a WebPy server on port 8080. But the DDNS service providers (like dlinkddns.com or dyndns.org) only allows port 80. I can run the server in port 80 with sudo command. But my server become vulnerable if i give root access. So I tried port forwarding in the router and server. But no use. I don't know if I done that correctly. Issue 2: Even though the server runs on port 80, I can access my site from my local machines only using registered domain names ( say, nikz.dyndns.org). No one on internet cannot load this site even when its totally up. As I observed server log, the request from other clients never reached my server. I need to run this server on port 8080 and i need to access this site from internet. How can I do it? any idea?

• another "SSH connect to host github.com port 22: Bad file number"

  - by Mariusz

  Hello. I have a problem with my first-time ssh connection. Yes, I've already done yours guides, already tried your "Dealing with firewalls and proxies" article and the problem is still occuring. I am using Win7 32bit, Windows Firewall is disabled, haven't any third-party firewalls, ESET Nod32 Antivirus is not blocking any ports, I am not using any PROXY (neither local proxy) .

• Virtual machines interconnection inside Proxmox 2.1 Cluster

  - by Anton

  We have 3 physical servers (each with 1 NIC) in different datacentres, all of them are interconnected by openvpn bridged private network (10.x.x.x). Inside this network we have fully functional 3 nodes Proxmox 2.1 cluster. So, actually question is: Is there any "proper" way to make "global" local network (172.16.x.x) for all VMs inside cluster, so even if we move VM from one node to other we could reach it by static IP regardless of it's physical location? BTW, we can't add dedicated NIC to each server. Thanks in advance. EDIT: I have tried to make a separate openvpn bridge for 172.16.x.x, now I have at each server two interfaces: SRV1: openvpnbr1 - 172.16.13.1 vmbr0 - 172.16.1.1 SRV2: openvpnbr1 - 172.16.13.2 vmbr0 - 172.16.2.1 But now there is no connection between those ifaces: SRV1: ping 172.16.13.2 From 172.16.1.1 icmp_seq=2 Destination Host Unreachable SRV2: ping 172.16.13.1 From 172.16.2.1 icmp_seq=2 Destination Host Unreachable If I shut down vmbr0 interfaces, so there is connection between servers over openvpn, but vmbr0 is used by Proxmox... Where I am wrong?

• How can I run Gnome or KDE locally in Cygwin?

  - by John Peter Thompson Garcés

  Apparently it is possible to do this using cygwin ports, as can be seen in screenshots. I followed this how-to to get apt-cygports set up, and I used it to install gnome-session. This how-to supposedly gives the commands needed to run Gnome or KDE, but whenever I try to run Gnome, a blank X-window pops up and then quickly disappears.

• Internet slowed down because of SQUID Server setup

  - by Ranjith Kumar

  Recently I have setup a squid server for our office. I have computer (A) with two ethernet cards, one for internet and the second one for local networkIt has Ubuntu server OS with squid-server and dhcp3-server installedI have added few iptable rules to work like a router and redirect all http traffic to 3128 port This link is my reference. Everything worked fine for 2 days. All of a sudden internet speed went down drastically. When I connected the internet cable to my laptop to test the internet speed it was fine. Again when I reconnected it back to computer A everything was normal. This happened 4 times in a week. Could anyone here please help me why the internet speed is going down and it becomes normal when I reconnect the cable. EDIT: Rebooting the system (computer A) didn't make a difference. I have changed iptables so that http traffic doesn't redirect to 3128 port any further, still no change in the internet speed. I think the problem is not with squid but with something else. Here are my iptable rules SQUID_SERVER="10.1.1.1" INTERNET="eth1" LAN_IN="eth0" SQUID_PORT="3128" PROXYSERVERS=(Atlanta Baltimore Boston Chicago Dallas Denver Houston KansasCity LosAngeles Miami NewYork Philadelphia Phoenix SanAntonio SanDiego SanJose Seattle Washington) SERVERLEN=${#PROXYSERVERS[*]} I=0 iptables -F iptables -X iptables -t nat -F iptables -t nat -X iptables -t mangle -F iptables -t mangle -X modprobe ip_conntrack modprobe ip_conntrack_ftp echo 1 /proc/sys/net/ipv4/ip_forward iptables -P INPUT DROP iptables -P OUTPUT ACCEPT iptables -A INPUT -i lo -j ACCEPT iptables -A OUTPUT -o lo -j ACCEPT iptables -A INPUT -i $INTERNET -m state --state ESTABLISHED,RELATED -j ACCEPT iptables --table nat --append POSTROUTING --out-interface $INTERNET -j MASQUERADE iptables --append FORWARD --in-interface $LAN_IN -j ACCEPT iptables -A INPUT -i $LAN_IN -j ACCEPT iptables -A OUTPUT -o $LAN_IN -j ACCEPT while [ $I -lt $SERVERLEN ]; do iptables -t nat -A PREROUTING -i $LAN_IN -p tcp -d ${PROXYSERVERS[$I]}.wonderproxy.com --dport 80 -j ACCEPT let I++ done iptables -t nat -A PREROUTING -i $LAN_IN -p tcp --dport 80 -j DNAT --to $SQUID_SERVER:$SQUID_PORT iptables -A INPUT --protocol tcp --dport 80 -j ACCEPT iptables -A INPUT --protocol tcp --dport 443 -j ACCEPT iptables -A INPUT --protocol tcp --dport 22 -j ACCEPT iptables -A INPUT -j LOG iptables -A INPUT -j DROP

• How can I find the USB wireless adapter into the dmesg log file?

  - by AndreaNobili

  I am pretty new in Linux (RaspBian for RaspBerry Pi but I think that there are not difference) and I have to install an USB wireless network adapter (the product is the TP-Link TL-WN725N, this one: http://www.tp-link.it/products/details/?model=TL-WN725N ) Now, I think that this is not automatically recognized by my system because if I execute ifconfig command I obtain the following output: pi@raspberrypi ~ $ ifconfig eth0 Link encap:Ethernet HWaddr b8:27:eb:2a:9f:b0 inet addr:192.168.1.8 Bcast:192.168.1.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:475 errors:0 dropped:0 overruns:0 frame:0 TX packets:424 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:34195 (33.3 KiB) TX bytes:89578 (87.4 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) So now it see only my ethernet network interface and not the wireless. So I was thinkig to try to see into the dmesg, but I don't know what have I to see and how to select it into the dmesg output. For example by the following command I can see the line of the dmesg log file relate to my ethernet port: pi@raspberrypi ~ $ cat /var/log/dmesg |grep -i eth [ 3.177620] smsc95xx 1-1.1:1.0 eth0: register 'smsc95xx' at usb-bcm2708_usb-1.1, smsc95xx USB 2.0 Ethernet, b8:27:eb:2a:9f:b0 [ 18.030389] smsc95xx 1-1.1:1.0 eth0: hardware isn't capable of remote wakeup [ 19.642167] smsc95xx 1-1.1:1.0 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 But what can I try to search for the USB wireless adapter? Tnx

• Slow network file transfer (under 20KB/s) on newly built x64 Win7

  - by Mangoshake

  I am getting <20KB/s for local network file transfer. If I transfer a very small file (less than 100KB) it would start quickly then slow down to <20KB/s. all subsequently network file transfer would be slow, a reboot is needed to reset this. If I transfer a large file it would be stuck on calculating for a long time and then begin with <20KB/s immediately. This is a newly built desktop running Windows 7 x64 SP1. Realtek gigabit LAN from the motherboard (ASRock Extreme3 gen3). Problematic speed is observed on the private LAN, both through ethernet and WiFi. The Router is D-Link DIR-655. Remote Differential Compression is off. Drivers are up-to-date from ASRock's website. I have tested network file transfer to and from another Windows 7 laptop and a MacBook Pro, so I am fairly certain it is the desktop's problem. The slow speed only happens with one direction also, outbound from the desktop, regardless of whether I initiate the file transfer action from the origin or the destination. Inbound network file transfer and internet speeds are fine, so I don't think this is a hardware issue. I am getting 74.8MB/s internet upload speed from speedtest.net (http://www.speedtest.net/result/1852752479.png). Inbound network file transfer I can get around 10-15MB/s. I am hoping this community has some insight for me to troubleshoot this. I don't see anything obviously related from the Event Viewer, and beyond that I just don't know where else to look. Any suggestions are greatly appreciated, thank you in advance.

• 2000 Server, User can't logon

  - by Mike I

  I hope you can help me. I recently upgraded a workstation at my office (to a whole new machine) and ran into a pretty serious problem. Friday until 5:00 PM, I could access my mail on 2000 Exchange server. When I shut the old workstation down and put in the new workstation, I tried to set up an account. When I put the server name in appropriate field and typed my username and hit check names, my username does not come up. So to troubleshoot, (It also is a SMB server) I try to logon to my file share. (My local credentials are the same as server credientials of user account) When I try to logon to share, I just get the Username/Password screen (Never had gotten that before since credentials are the same) Again, in troubleshooting mode, I try to log on to my user from another workstation. Still can't authenticate via my user. Every other user can authenticate and load up their shares/mailboxes. I have restored Exchange from the backup as of 3 days ago (Thursday) but the exact same issue is still there. I really do not understand what is wrong and what else I can do to troubleshoot. If anyone has some pointers for me, I will surely accept them. Thanks, Mike

• Connecting XRAID to Sunfire via LSI FC card - Drives not showing up

• Compiled ruby fails to find curses

  - by Hamish Downer

  I'm attempting to install the sup MUA but I'm having trouble. When I try to run it, it can't find curses: /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- curses (LoadError) ... I am installing on a server running CentOS 5. I have compiled ruby and rubygems from source, and then installed sup using rubygems. I followed this article to compile ruby. I have found having a similar problem on ubuntu. The fix suggested there is to install libcurses-ruby, but I can't find a similarly named package in CentOS. I have installed the ncurses-devel package, as that was required for installing sup using gem. I have also installed the ncurses, cursesx and rbcurse gems, but none of these have fixed the problem. The article above about compiling ruby said you had to recompile the zlib extension, after doing: cd ext/zlib sudo ruby extconf.rb --with-zlib-include=/usr/include --with-zlib-lib=/usr/lib cd ../.. sudo make sudo make install So I've tried a few variants in ext/curses. The top few lines of ext/curses/extconf.rb are require 'mkmf' dir_config('curses') dir_config('ncurses') dir_config('termcap') So I've tried a few variants of setting paths: sudo ruby extconf.rb --with-curses-include=/usr/include --with-curses-lib=/usr/lib --with-ncurses-include=/usr/include --with-ncurses-lib=/usr/lib --with-termcap-lib=/lib sudo ruby extconf.rb --with-curses-include=/usr/include --with-curses-lib=/usr/lib --with-termcap-lib=/lib and re-doing the make, but to no avail as yet. Any ideas to move it forward are welcome.

• WSUS trying to download all updates again

  - by Tim Alexander

  The server hosting WSUS had a catastrophic failure and we have had to rebuild the system drives. Luckily the DB and content store for WSUS are on a seperate drive so were unaffected. During the rebuild process we thought it was time to update the server to 2008 R2 (from 2003 R2). Have got the server running and installed the WSUS role, detached the DB form SQL Express 2008 R2 and attached the original. Carried out the wsusutil.exe movecontent command with a -skipcopy switch pointing to the original content store. All looked good until I saw the front page stating it is trying to download files for 6,436 updates at around 344,565 MB!!!!!! Oops, I thought, something not right here. The content store I have on disk is only 75GB but I am thinking that some vital step has been missed in the restoration process. Either way is there a way to make WSUS reindex its local content store or something as I am unsure that downloading 344 gigabytes is a viable way forward! EDIT: Never rains but it pours. AM now getting a CLSID: FX {8b6499ed-0241-e032-6508-da4b1c879d7e} error could not create snap in. think a reinstall of WSUS is in order.

• ISA Server dropping packets as it believes they are spoofed

  - by RB

  We have ISA Server 2004 running on Windows Server 2003 SP2. It has 2 NICs - one internal called LAN on 192.168.16.2, with a subnet of 255.255.255.0, and one external called WAN on 93.x.x.2. The default gateway is 93.x.x.1 (our modem). This machine also accepts VPN connections. We are having a problem with a scanner, which is trying to save a scan into a network share. Every time we try to scan, ISA Server logs the following Denied Connection Log type: Firewall service Status: A packet was dropped because ISA Server determined that the source IP address is spoofed. Rule: Source: Internal ( 192.168.16.54:1024) Destination: Internal ( 192.168.16.255:137) Protocol: NetBios Name Service Pinging 192.168.16.54 from the ISA Server works fine. In ISA Server, going into Configuration → Networks, there are 5 Networks : - External (inbuilt) - Internal (defined as 192.168.16.0 → 192.168.16.255) - Local Host (inbuilt) - Quarantined VPN Clients (inbuilt) - VPN Clients (inbuilt) Finally, under Network Connections → Advanced → Advanced Settings..., the connections are in the following order : - LAN - WAN - [Remote Access Connections] If we try to scan onto a workstation it works fine. Please let me know if you need any more info - many thanks. RB.
