• How to bypass firewall to connect to a proxy server?

  - by Bruce

  I am conducting a small experiment on my office network. I have setup a proxy server on my desktop machine (connected to my LAN) and I have volunteers access the internet via my proxy server. Everything is working well. The problem is people cannot connect to the proxy server through their laptops. I asked my network admin and he said the wireless network has a firewall which prevents users from connecting to my proxy. He said I could tunnel the traffic or use SSH though. I am afraid I do not understand fully what is going on. Is there a way by which users connected on the wireless network can connect to my desktop? I am using FreeProxy on Windows as my proxy server: http://www.handcraftedsoftware.org/index.php?page=download FreeProxy allows me to create a SOCKS 4/4a/5 proxy. Is that what I need? Part of the experiment involves logging the URL requests of the users. I am doing a measurement study. So, any solution must allow me to log the URL requests of users. Also, what changes do I need to make in the browser configuration.

• Can I make two wireless routers communicate using the wireless?

  - by Dana Robinson

  I want to make a setup like this: cable modem <-cable- wireless router 1 <-wireless- wireless router 2 in another room <-cables- PCs in another room Basically, I want to extend my network access across the house and then have a bunch of network jacks available for my office PCs. Right now, I have a cable modem going to a wireless router in one room and a PC with a wireless PCI card in it in the office on the other side of the house. I use internet connection sharing with the other PCs in the office. The problem is that ICS is flaky, especially when I switch to VPN on the Windows box to access files at work. I picked up a wireless USB adapter that I thought I could share among the PCs I work on but I'm not very happy with it so I'm going to return it (NDISwrapper support for it is poor). Is this possible? My wireless experience so far has been pretty straightforward so I have no idea what kind of hardware is available. I've looked at network extenders but those just look like repeaters for signal strength. I want wired network jacks in my office.

• How to increase wifi speed for laptops

  - by sagar

  Now, Let me explain the situation. I am having a query regarding Wi-Fi network. I am having PC & laptop. I requested my Wi-Fi providers that I want connection in my PC. So that - Wi-Fi provider set up an Antenna on my building Terrace - They joined a cable to pc & that Antenna. ( I think using RJ45 connector ) - The reason behind this - my does not have a built in Wi-Fi adapter. Now - almost laptops have built in Wi-Fi. Now - On terrace there is Wi-Fi with superb speed. But on my flat - Wi-fi comes with low speed. So, when ever I use internet on my pc - it has great speed - but my laptop works with low speed. The reason behind this - PC is catching wifi from terrace & laptop is catching the wifi from it's own place. Now, My question is something like this. Can we place an antenna or something like that & connect it to laptop for better wifi speed? ( I am not technical person - Please add comment for down vote - if any ) ( Please add comment for more explanation of my Problem ) Thanks in advance for sharing your knowledge. Sagar

• shutdown.exe on Win Server2k3 64-bit cannot be found

  - by normalocity

  Server 2003 SP2 64-bit Verified my path settings are correct, as I can run other executables within the "system32" folder without issue. If I cd to "c:\windows\system32\" folder, and try to run "shutdown /?" I get "shutdown is not recognized as a valid..." you know - the message you get when you type a command that doesn't exist. Doing a "dir *.exe" inside the "system32" folder, also doesn't return "shutdown.exe" as one of the results. HOWEVER - if I go through Windows Explorer - there it is! I can see shutdown.exe. Also, if I go to "Start - Run" and type "shutdown /?", it works fine. So, works in the GUI, not on the command line. very strange. This is an excerpt of the last portion of "dir *.exe" when run on the "system32" folder. Note the lack of commonly used executables such as "shutdown.exe" and "tsadmin.exe" 02/18/2007 07:00 AM 24,064 route.exe 02/18/2007 07:00 AM 29,184 routemon.exe 02/18/2007 07:00 AM 14,848 rsh.exe 02/18/2007 07:00 AM 67,072 rsopprov.exe 02/18/2007 07:00 AM 77,824 rtcshare.exe 02/18/2007 07:00 AM 18,432 runas.exe 02/18/2007 07:00 AM 34,816 rundll32.exe 02/18/2007 07:00 AM 18,432 runonce.exe 02/18/2007 07:00 AM 13,312 savedump.exe 03/19/2009 07:51 PM 49,152 sc.exe 02/18/2007 07:00 AM 90,112 scardsvr.exe 02/18/2007 07:00 AM 152,064 schtasks.exe 02/18/2007 07:00 AM 16,384 schupgr.exe 02/18/2007 07:00 AM 31,232 sdbinst.exe 02/18/2007 07:00 AM 36,352 secedit.exe 02/18/2007 07:00 AM 32,768 sethc.exe 06/28/2006 12:12 AM 31,232 SetLACState.exe 02/18/2007 07:00 AM 41,472 setup.exe 02/18/2007 07:00 AM 25,088 setup16.exe 02/18/2007 07:00 AM 20,480 setupn.exe 02/18/2007 07:00 AM 60,416 setx.exe 02/18/2007 07:00 AM 10,752 sfc.exe 02/18/2007 07:00 AM 76,288 sfmprint.exe 02/18/2007 07:00 AM 11,776 sfmpsexe.exe 02/18/2007 07:00 AM 65,024 sfmsvc.exe 02/18/2007 07:00 AM 38,400 shmgrate.exe 02/18/2007 07:00 AM 71,168 sigverif.exe 02/18/2007 07:00 AM 26,112 skeys.exe 02/18/2007 07:00 AM 96,256 smlogsvc.exe 02/18/2007 07:00 AM 53,760 smss.exe 02/18/2007 07:00 AM 40,960 snmp.exe 02/18/2007 07:00 AM 25,088 sort.exe 02/18/2007 07:00 AM 9,728 sprestrt.exe 02/18/2007 07:00 AM 10,240 subst.exe 02/18/2007 07:00 AM 14,848 svchost.exe 02/18/2007 07:00 AM 54,272 syncapp.exe 02/18/2007 07:00 AM 18,896 sysedit.exe 02/18/2007 07:00 AM 29,696 syskey.exe 02/18/2007 07:00 AM 107,520 sysocmgr.exe 02/18/2007 07:00 AM 79,360 systeminfo.exe 02/18/2007 07:00 AM 3,072 systray.exe 02/18/2007 07:00 AM 58,880 takeown.exe 02/18/2007 07:00 AM 32,768 tapicfg.exe 02/18/2007 07:00 AM 84,480 taskkill.exe 02/18/2007 07:00 AM 87,552 tasklist.exe 02/18/2007 07:00 AM 168,960 taskmgr.exe 02/18/2007 07:00 AM 13,824 tcmsetup.exe 02/18/2007 07:00 AM 21,504 tcpsvcs.exe 02/18/2007 07:00 AM 28,672 timeout.exe 02/18/2007 07:00 AM 419,328 tracerpt.exe 02/18/2007 07:00 AM 12,800 tracert.exe 02/18/2007 07:00 AM 26,624 tsecimp.exe 02/18/2007 07:00 AM 37,376 typeperf.exe 10/24/2008 04:12 PM 64,000 tzchange.exe 02/18/2007 07:00 AM 5,632 unlodctr.exe 02/18/2007 07:00 AM 321,024 upg351db.exe 02/18/2007 07:00 AM 16,896 ups.exe 02/18/2007 07:00 AM 4,096 user.exe 02/18/2007 07:00 AM 26,112 userinit.exe 02/18/2007 07:00 AM 49,152 utilman.exe 02/18/2007 07:00 AM 47,104 uwdf.exe 02/18/2007 07:00 AM 29,184 verclsid.exe 02/18/2007 07:00 AM 112,640 verifier.exe 02/18/2007 07:00 AM 1,129 vwipxspx.exe 02/18/2007 07:00 AM 55,296 w32tm.exe 02/18/2007 07:00 AM 38,400 waitfor.exe 02/18/2007 07:00 AM 39,424 wdfmgr.exe 02/18/2007 07:00 AM 62,464 wextract.exe 02/18/2007 07:00 AM 38,400 where.exe 02/18/2007 07:00 AM 48,640 whoami.exe 02/18/2007 07:00 AM 36,864 winchat.exe 08/13/2007 06:45 PM 206,336 WinFXDocObj.exe 02/18/2007 07:00 AM 8,704 winhlp32.exe 02/18/2007 07:00 AM 12,800 winmsd.exe 02/18/2007 07:00 AM 2,112 winspool.exe 02/18/2007 07:00 AM 6,656 winver.exe 08/21/2002 05:13 AM 189,952 WISPTIS.EXE 02/18/2007 07:00 AM 67,072 wlbs.exe 02/18/2007 07:00 AM 10,560 wowexec.exe 02/18/2007 07:00 AM 10,752 wowreg32.exe 02/18/2007 07:00 AM 31,232 wpnpinst.exe 02/18/2007 07:00 AM 5,632 write.exe 02/18/2007 07:00 AM 114,688 wscript.exe 02/18/2007 07:00 AM 30,720 xcopy.exe

• Windows Server 2003 DHCP not handing out IPs

  - by SnOrfus

  I'm trying to setup a home server (to tinker with) as a domain controller. I've setup the domain and I've installed DHCP and setup a scope without any exclusions (with the default range of 192.168.0.1-254). My client machine is a Windows 7 (RC) machine and it has a connection but can't get an IP address. Even if I try setting the IP to a static 192.168.0.2 and there is still no connectivity. I can ping it from the server, but pinging the server from the client just times out. The only thing between the server and the client is a 24 port switch (D-Link DES-1024D). edit Ok, it turned out that the interfaces were setup backwards in the NAT settings (the internal nic connection was set to public and the external nic connection was set to private). I changed this and all was OK.... sort-of. Problem is now: If I set a static ip on the client (where I am typing this from) all is fine. BUT; when I set it to get it from DHCP, I get a correct IP from the server (192.168.0.2) but there is no internet on the client; but I can still ping the server fine from the client (which makes sense cause I was able to get an IP from it). edit I ended up just removing the Routing and DHCP server roles and just going with ICS for the time being until I get my hands on some better learning tools.

• How to setup Calendar permissions for group to group

  - by Sorean

  I've been scouring the internet and so far have only been able to find examples of how to grant calendar permissions from one user to another using the Add-MailboxFolderPermission command. This is great and it was okay for when they only had a handful of users. But going forward it's not realistic to have to set individual calendar permissions for all calendars for each new user. Layout of security groups already created. Each group has a few people assigned to it. Techs Managers Admin What I am trying to accomplish is set it up so that anyone that belongs to the Managers group can view the calendars of the Tech group. Admins can view and edit the Tech group. I've found an example of adding just the security group name but I get an error of: [PS] C:\Windows\system32add-MailboxFolderPermission -Identity Techs:\Calendar -User "Admin" -AccessRights Owner The user "Admin" is either not valid SMTP address, or there is no matching information. + CategoryInfo : NotSpecified: (0:Int32) [Add-MailboxFolderPermission], InvalidExternalUserIdException + FullyQualifiedErrorId : 39352699,Microsoft.Exchange.Management.StoreTasks.AddMailboxFolderPermission Am I creating groups wrong? Am I using the wrong commands? Any guidance would be greatly appreciated.

• Cisco ASA and static IPv6 tunnel endpoint?

  - by Martijn Heemels

  I recently installed a Cisco ASA 5505 firewall on the edge of our LAN. The setup is simple: Internet <-- ASA <-- LAN I would like provide the hosts in the LAN with IPv6 connectivity by setting up a 6in4 tunnel to SixXS. It would be nice to have the ASA as tunnel endpoint so it can firewall both IPv4 and IPv6 traffic. Unfortunately the ASA apparently can't create a tunnel itself, and can't port-forward protocol 41 traffic, so I believe I would have to do one of the following instead: Set up a host with it's own IP outside the firewall, and have that function as tunnel-endpoint. The ASA can then firewall and route the v6 subnet to the LAN. Set up a host inside the firewall that functions as endpoint, separated via vlan or whatever, and loop the traffic back into the ASA where it can be firewalled and routed. This seems contrived, but would allow me to use a VM instead of a physical machine as endpoint. Any other way? What would you suggest is the optimal way to set this up? P.S. I do have a spare public IP address available if needed, and can spin up another VM in our VMware infrastructure.

• Browsing Playstation 3 from Ubuntu Box

  - by zfranciscus

  Hi, My Goal here is to be able to transfer files from my Ubuntu 10.04 box to my PS3 over a wireless network. My PS3 and my Ubuntu Box is on the same home network. These are some stuff that I tried: I can't see my PS 3 from 'Places ? Network' nor other computer that is running on windows. I am still puzzled by this fact. I have not tried ping-ing my PS3. I'll try that later today and post the result in the forum I install PS3MediaServer (http://code.google.com/p/ps3mediaserver/). Someone in the PS3 chat forum (http://www.ps3chat.com/playstation-3...lp-please.html) claims that it will enable your ubuntu box to browse PS3. So I downloaded PS3MediaServer, and ran the software. The status tab keep showing "Waiting ...". It seems that PS3MediaServer can't find my PS3. Some how I feel that 1 and 2 are related somehow.Perhaps that there is something wrong with my Ubuntu network settings that is preventing my ubuntu box from looking up other device on the network. I can go to the Internet fine, but I can't see other device on my network. Does anyone have any experience in this area. I would like to hear your experience and perhaps some solution. Any kind of hints or help will be greatly appreciated. Cheers

• IPv4 not enabled in Windows 7

  - by RidDeBakTiYar

  I have a Netbook with Win 7 Starter edition. I am not able to get IPv4 enabled/installed in the Netbook and hence not able to network/connect to Internet. It says "Limited access" when I check connections. It all began when my system crashed and I was not able to get thro beyond the boot screen. The system advice me to try repair with the original OS cd and I did the same. After that the Netbook has booted, but is not able to network. On a detailed study I found that the Network adapter has both IPv4 and IPv6 Protocols, but there are some differences. The IPv4 is not having the "Properties" enabled to configure, while the IPv6 is having "Properties" enabled. I have only a IPv4 Wired and Wireless at home and its not able to get the Netbook connected as it cannot I had tried uninstalling the Adapter to allow windows to automatically detect and install. Using the "netsh" command to uninstall and install, but not having any change in status. There is a option to "Have disk" under add Protocol, but I don't know how to give the standard IPv4 for installation (asking for *.inf). Any help in solving the issue will be very much appreciated

• How do I keep folders synced and backed up between two macs using a Linux NAS (rsync?)

  - by Hultner

  I've got two primary computers, one Mac Pro and one MacBook Pro for when I'm on the go. I've also got a Linux sever which also acts as NAS. Currently I backup the entire computers to an external drive with Time Machine which is rather useless and doesn't sync anything. What I really want to do is to keep my important files synced between both computers and my NAS (which is running RAID 5), that way I'm not backing up easily replaceable systemfiles and I've got all my important files in 3 places where two of them are running raid so at least 5 drives would have to crash at the same time before actual data loss occur. Folders I want to keep synced is basically my photo, documents, development, mamp and work folders and then I want to keep the user library folder backed up but not synced. I'm thinking that I'd have to use rsync but don't know how. Before suggesting Dropbox and similar suggestions I don't want to use them because of several reasons some of them being security (Dropbox obviously proved this), Speed (sometimes I'll sync gigabytes of data and that will be significantly faster locally and probably even through VPN as I have a Gigabit pipe), Space (space on my NAS is cheap and only practically limited by my needs), reliability (even if my internet were to go down I still need to be able to keep my files synced incase I'd need to go somewhere on the fly), price (I already have all the hardware and for the amount of gigabytes and bandwidth I'd need I doubt that there's any free or cheap service). Those are my main reason for wanting to keep it locally. I'm sorry for any spelling or grammatical mistakes that I've might have done. I'm writing this on my smartphone from a shaky train and English isn't my mother tongue. I gratefully appreciate any answers even if only partly solving my problem.

• GTX 280 purple snow on bootup, card works without drivers

  - by Brokar

  i have owned a ASUS GTX280 for 3 years now. The card has been great all along but i started having problems 10 days ago. I was playing Diablo 3 for 1 week on max settings no problems, then suddenly my display kept getting some weird purple/colours as soon as i booted and logged into windows. Went into safe mode, updated drivers and it kept crashing. Formatted PC, fresh windows install with new WHQL drivers again same problem. Uninstalled nvidia drivers and pc has been running great for 4 days now, ofcourse i cannot run games but everything works on 1680x1050 resolution and i can browse internet,watch movies and use my PC for everything but gaming. As soon as i install nvidia drivers PC won't boot. I only wanna game a few hours a week (very busy program with school this month so it might be a blessing that i cannot game) and i would love it if i could keep the card. I am looking to upgrde later on when i will have time for gaming but i wonder if i could still use the card somehow with different/new drivers (tried older drivers that came with the card on a CD aswell) tldr: PC works fine with no nvidia drivers (apart from gaming ofc). Once i install WHQL drivers or older ones, cannot even log into windows. Fix?

• Trouble with local id / remote id configuration of VPN

  - by Lynn Owens

  I have a NetGear UTM firewall and a Windows machine running NetGear's VPN client. The Windows machine I can put on the UTM network and take off of it. When I am cabled into the local (internal) the following configuration works: UTM: Local Id: Local Wan IP: (The UTM's WAN IP address) Remote Id: User FQDN: utm_remote1.com Client: Local Id: DNS: utm_remote1.com Remote Id: (The UTM's WAN IP address) Gateway authentication: preshared key Policy remote endpoint: FQDN: utm_remote1.com But when I'm off the UTM's internal local network and simply coming in from the internet, this does not work. It simply repeats SEND phase 1 before giving up. Since I know that the UTM WAN IP is accessible from both inside and outside the network, I figured the problem was with the Client local id. So, I tried the following: UTM: Local Id: Local Wan IP: (The UTM's WAN IP address) Remote Id: (A DN of a self-signed certificate I created for the client and uploaded into the UTM certificates) Client: Local Id: (The DN of the aforementioned self signed cert) Remote Id: (The UTM's WAN IP address) Gateway authentication: (the aforementioned self signed cert) Policy remote end point: ... er, ... my choices are IP and FQDN.... Not sure what to put here No matter what I've tried, it just keeps repeating the SEND phase 1. Any ideas?

• Project and Business Document Organization

  - by dassouki

  How do you organize, maintain edits, revisions and the relationship between: Proposals Contracts Change Orders Deliverables Projects How do you organize your projects for re-usability? For example, is there a way to add tags to projects, to make them more accessible? What's a good data structure to dump all my files on an internet server for easy access? Presently, my work folder is setup as follows: (1)/work/ (2)/projects (3)/project_a (4)/final (which includes all final documents) (5)/contracts (5)/rfp_rfq (5)/change_orders (5)/communications (logs all emails, faxes, and meeting notes and minutes) (5)/financial (6)/paid (6)/unpaid (5)/reports (4)/old (include all documents that didn't make it into the project_a/final/ (3)/project_b (4) ... same as above ... (2)/references (3)/technical_references (3)/gov_regulations (3)/data_sources (3)/books (3)/topic_based (each area of my expertise has a folder with references in them) (2)/business_contacts (3)/contacts.xls (file contains all my contacts) (2)/banking (3)/banking.xls (contains a list of all paid and unpaid invoices as well as some cool stats) (3)/quicken (to do my taxes and yada yada) (4)/year (2)/education (courses I've taken (3)/webinars (3)/seminars (3)/online_courses (2)/publications (includes the publications I've made (3)/publication_id We're mostly 5 people working together part-time on this thing. Since this is a very structured approach, I find it really difficult to remember what I've done on previous projects and go back and forth easily. What are your suggestions on improving my processes? I'm open to closed and open source software (as long as the price isn't too high). I also want to implement a system where I can save most of the projects online to increase collaboration and efficiency and reduce bandwidth especially on document editing. Imagine emailing a document back and forth 5-10 times a day.

• Cisco SA520 to Adtran 1234 no DHCP transfer

  - by Grico

  I am trying to set up a Cisco SA520 to run DHCP on my network. I have a vendor provided switch, the Adtran 1234, and it provides DHCP for our phone systems on VLAN 200. I do not have access to the Adtran, but the vendor gave me a IP on port 1 for WAN and said port 2 should be for the "trust" side should go. I did setup a mini lab where, Adtran 1 went to SA520 WAN port, and SA520 trust 1 went to my laptop. Everything worked fine, I could ping and get internet using the DHCP scope I put on the SA520. I then unplugged my computer from SA520 trust 1 and plugged it into Adtran 2. I plugged my computer into Adtran 23 and I dont get DHCP or even a link light. If I restart my machine, I get a brief link and then it dies once the machine boots. I have tried several ports on the Adtran and none seem to work. Different cables as well. However, when I plug a phone into the Adtran, the phone boot immediately and shows link. Thoughts?

• Can't connect two PCs to a Network Switch at the same time (Windows 7)

  - by puk

  I have two computers connected to a network switch and every once in a while one of the computers will lose its internet connection. It's almost always the same computer every time. However, if I play around with the control panel, I can switch it, so that now the other computer is not connected. Restarting either of the computers does not help either. In Windows, the worlds-greatest-trouble-shooter tells me that a network cable is unplugged and that I should try plugging it in...Disabling and re-enabling my NIC does not fix this problem, neither does swapping cables around. When rebooting, the BIOS complains about how the Ethernet Cable is not plugged in. If it's in any way important, My set up at the office is like so: Modem - Routher - Network Switch 1 - Network Switch 2. I have tried turning off the energy saving option for my NIC, and I tried manually setting the link-speed to 100Mbps Full Duplex without any luck. Also, I have a Realtek PCIe GBE Family controller on both computers Does anyone have any idea why this is happening every 5-10 days? EDIT: I have also tried using a completely different Network Switch and the problem still persists as before.

• Odd IIS FTP Failure

  - by Monkey Boson

  We're running a script on our production box that zips up our database and FTPs it to a backup box every night. Our production box is running Redhat Enterprise 5. Our backup box is running Windows XP Pro / IIS 5.1. Both machines are on the same VLAN (not sure if this is imporatant). The backup file usually clocks in at around 3GB. Every now and again (~5% of the time), the backup script fails. The shell script on the "client side" - which looks at return codes - never identifies any problem since ftp always returns 0. On the "server side", IIS writes out a log that looks like this: #Software: Microsoft Internet Information Services 5.1 #Version: 1.0 #Date: 2009-08-08 07:04:25 #Fields: time c-ip cs-method cs-uri-stem sc-status sc-win32-status 07:04:25 192.168.111.235 [15]USER backup 331 0 07:04:25 192.168.111.235 [15]PASS - 230 0 07:05:54 192.168.111.235 [15]created backup_20090808.zip 426 10035 07:06:16 192.168.111.235 [15]QUIT - 426 0 Now, I know that 426 means "Connection closed, transfer aborted", which is sort-of a catch-all for "IIS was not happy". The real puzzler is the wincode: 10035 (WSAEWOULDBLOCK -- Resource temporarily unavailable). My understanding is that this code is normal when using non-blocking socket calls - which would almost certainly be used by any FTP Server implementation. My first guess that it might be a timeout issue doesn't make sense, since we're only talking about a few minutes here and the timeout was left at the default 900 s. Does anybody have any ideas about what is causing this problem, and how it may be fixed? Thanks!

  I've an interesting problem that I thought was straightforward, but turns out I think I'm whistling down the wrong path. It has to do with (shudder) email. I thought I was done with needing to know about email guts ten years ago; I was wrong. Anyway. Simply put, I need to figure out how to relay outgoing email that is not targetted in our domain from our domain into a 'dropbox' in a DMZ, and the Other Guys can retrieve that email from their side of the DMZ and distribute it accordingly, even out to the public internet if need be. There will be no [un-established] traffic coming back to Our side from anywhere; any attempts to do so are dropped with malicious prejudice. Our side is postfix running on scilinux6.1. The DMZ boxes are redhat5.4. The Other Guys are M$ Exchange. The firewalls are set up such that data can go from Our Side downsec to the DMZ, but not upsec from the DMZ into Our Side. Same for the Other Guys. My first thinking was simply to set up postfix on a box in the DMZ and tell them to set up fetchmail or whatever the M$ equivalent is, but then I started remembering that postfix wants to actively relay email onwards, rather than hold it and wait for someone to 'reach in' and retrieve it. I'm not sure I've explained this well, but hopefully it's clear enough that someone can point me in the right direction. I seem to remember having done this before, but it was a looong time ago. thanks!

• IIS8 behind a VPN + Windows Server 2012 - how to properly bind IP+Port

  - by ryugen

  This is my first question so I hope I'm going to give you enough information. I'm running Windows Server 2012 within the Hyper-V environment of my Windows 8 machine. Within Windows Server 2012 I'm running a VPN tool based on openVPN to hide my real IP. When I run IIS8 with the VPN disconnected it works flawlessly through the Internet (port 80 forwarded correctly). But as soon as I connect to the VPN I can't reach my site through the domain anymore. Now I tried basically everything I know which is why I'm asking you guys. I tried binding IIS8 to the IP of my virtual ethernet card. I tried changing the priority of the NIC through the "Network and sharing center" via the advanced tab. I used ipconfig /flushdns in case there was something wrong in the DNS handling. Hell, I even turned off the Windows firewall. I also used a port scanner to verify the problem. The webserver is reachable on port 80 with VPN disconnected and immediately gets unreachable on connect. Theoretically both IPs (my regular one AND the VPN) should be reachable or at least not impair the other one right? Do you have any other suggestion? Do I have to route something somewhere somehow?

• SQL Server 2005 - Linked Visual Foxpro Authorization

  - by John

  Here's the Scenario: We have an existing SQL 2000 Server that has a linked server to a share directory (on another server) containing Visual FoxPro tables; all connections work correctly. Porting the SQL 2000 server to a new SQL 2005 server results in questionable behavior: If you connect to the server, remotely, using Windows Authentication, you receive this error when running a query against the linked server: OLE DB provider "MSDASQL" for linked server "[linked server name]" returned message "[Microsoft][ODBC Visual FoxPro Driver]File 'MyTable.dbf' does not exist.". Msg 7350, Level 16, State 2, Line 2 Cannot get the column information from OLE DB provider "MSDASQL" for linked server "[linked server name]". However, logged in locally, the query works fine. The query also works correctly when logged in remotely, but using a SQL login. The only scenario I receive the error is when connected remotely, using windows authentication. As I mentioned before, this works on the SQL 2000 server, and both the old and new servers are running under the same network account (which has access to the folder the FoxPro files are in). Doing a little searching on the internet it looks like others have run into this situation, but I haven't found a resolution. Has anyone run into this before?

• special case ssh connection lag

  - by Hersheezy

  Setup We have a DMZ and LAN in our office that are connected to the outside with the following setup: +------+ | |------> LAN (normal office router) |Modem | | |------> DMZ (a single machine) +------+ Our internet account is with Comcast and we have 5 status IPs, one of which points to the single machine in the DMZ. Problem ssh connections initiated ANYWHERE EXCEPT the office LAN are really fast. However, from the LAN, there is about a 5 second delay. WTF?? Extra info The DMZ machine is debian 5. Executing a wget to the DMZ has no lag.

• How can ICS in Windows 7 be managed via command line, scripts, config files, etc.?

  - by Skya

  I've been using ICS successfully for years, but now I'm looking for a way to control it through something else than the GUI in Control Panel\Network and Internet\Network Connections - Connection Properties: I want to do everything that the encircled checkbox does, without touching the GUI. But what does the checkbox do? Microsoft don't provide specific information and the most helpful forum post I've found is from 2003. Assuming that some of the advice is still valid, I've come to the conclusion that ICS is broken down into 6 parts that have to be set up individually: the sharedAccess service interface settings firewall rules a static route dnsproxy autodhcp I've already learned that the service can be started/stopped with the command net start/stop sharedAccess and that netsh is a good tool for changing the interface settings and the firewall rules. But I don't understand how ICS handles routing and DNS. All hosts in my network are configured statically, so I don't care much about autodhcp. Thanks for your help! EDIT: I've spent the whole day scanning through ProcMon and I've seen reads/writes to both the registry and the filesystem and it is difficult to determine what parts of it actually make ICS work. I'm trying to look for an API instead. I'm looking into this right now, but I still want to know more about the inner workings.

• Windows 7 - system error 5 problem

  - by Ian

  My wife has just had a new computer for Christmas (with an upgrade from VISTA to Windows 7), and has joined the home network. We are using a mix of WindowsXP and Ubuntu boxes linked via a switch. We are all in the same workgroup. (No domain). Internet access, DHCP, and DNS server is an SME server that thinks it is domain controller (although we are not using a domain). I need to run a script to back up my wife's machine (venus). In the past the script creates a share on a machine with lots of space (leda), and then executes the line. PSEXEC \\venus -u admin -p adminpassword -c -f d:\Progs\snapshot.exe C: \\leda\Venus\C-drive.SNA With the wife's old XP machine, this would run the sysinternals utility, copy shapshot,exe to her machine and run it, which would then back up her C: drive to the share on leda. I cannot get this to work with Windows 7, nor can I link through to the C$ share on her machine. This gives me a permissions error (system error 5). The admin account is a full admin account. And yes - I do know the password. The ordinary shares on her machine work fine! I guess I'm missing something that Microsoft have built into Windows 7 - but what? The machine is running Windows 7 business, with windows firewall, AVG anti virus, and all the crap-ware you get with a new PC removed. Thanks

• Member Status: Inquorate in RHEL 5.6

  - by Eugene S

  I've encountered a strange issue. I had to change the time on my Linux RHEL cluster system. I've done it using the following command from the root user: date +%T -s "10:13:13" After doing this, some message appeared relating to <emerg> #1: Quorum Dissolved (however I didn't capture the message completely). In order to investigate the issue I looked at /var/log/messages and I've discovered these errors. Below is the output of few commands I got when tried to investigate the issue, however I don't have enough knowledge to make use of this information.

• Cannot connect on TFS 2012 server through SSL with invalid certificate

  - by DaveWut

  I saw the problem on some forums and even here, but not as specific as mine. So here's the thing, So I've configured a TFS 2012 server, on one of my personnel server at home, and now, I'm trying to make it available through the internet, with the help of apache2 on a different UNIX based, physical server. The thing is working perfectly, I don't have any problem accessing the address https://tfs.something.com/tfs through my browser. The address can be pinged and I do have access to the TFS control panel through it. How does it work? Well, with apache2 you can set a virtual host and set up the ProxyPass and ProxyPassReserver setting, so the traffic can externally comes from a secure SSL connection, through a specified domain or sub-domain, but it can be locally redirect on a clear http session on a different port. This is my current setup. As I already said, I can access the web interface, but when I'm trying to connect with Visual Studio 2012, it can't be done. Here's the error I receive: http://i.imgur.com/TLQIn.png The technical information tells me: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. My SSL certificate is invalid and was automatically generated on my UNIX server. Even if I try to add it in the Trusted Root Certification Authorities either on my TFS server or on my local workstation, it doesn't work. I still receive the same error. Is there's a way to completely ignore certificate validation? If not, what's have I done? I mean, I've added the certificate in the trusted root certificates, it should works as mentioned on some forums... If you need more information, please ask me, I'll be pleased to provide you more.

• Cannot establish a network connect to VMWare Fusion VM

  - by twolfe18

  I am running Snow Leopard 10.6.2 (not the server edition) with VMWare Fusion 3.0.0 and I trying to get my Ubuntu 9.10 x86_64 VM working. I am using a bridged connection, and I have an internet connection FROM the Ubuntu VM (I can download updates, ping websites, etc), but I cannot connect TO the Ubuntu box from any other device on my network. I am trying to get Mongrel up on the Ubuntu VM for some Rails stuff, but it's not working. I know Mongrel/Rails is not the problem because if I start the server on the Ubuntu VM, background the process, and then wget the index page, it works. I just cannot connect to the site from another IP. I have tried using a static IP and a DHCP IP configuration on the Ubuntu VM, neither work (for incoming connections, both work for outwards). I have port scanned the Ubuntu VM, and it appears that all ports are closed. However, the Ubuntu VM does respond to pings. I noticed a similar question here: http://serverfault.com/questions/99757/setting-up-a-bridged-network-with-vmware-fusion, but no answer. Any ideas?
