• hg clone has stopped working on my Vista box

  - by vkraemer

  I have a Windows Vista machine that has been connecting to http://hg.netbeans.org productively for awhile... until recently. Lately, when I attempt to pull or clone, the update appears to stall... I see the following messages on the screen when I attempt to clone: destination directory: web-main requesting all changes adding changesets And then... nothing happens. I have opened the Task Manager and there doesn't appear to be any significant network activity for HOURS. I can contact the server with FireFox and see the proper output. I can clone from the repo with Solaris and/or Mac OS X... so the issue doesn't appear to be at the 'other end'. I had been running a fairly old version of Mercurial before this started happening. After it started happening, I upgraded to Mercurial 1.5.2.. which did not help resolve the issue at all. What are the likely causes and work-arounds for this?

• Windows 7 keeps asking for WIFI credentials

  - by RubenGeert

  If I want to log onto our WIFI network, Windows keeps asking for credentials. After many connection attempts (and sometimes some reboots) we finally manage to connect. Then the connection usually stays intact for the rest of the day. But it sometimes takes 15-20 minutes before we're online... Needless to say we're using a single username/password for all failing/succeeding attempts. Does anybody recognize these symptoms? How to troubleshoot this?

• WLAN adapter on Ubuntu Server inside Hyper-V

  - by Firefox333

  I need to set up an Ubuntu server as a router. However we need to make it wireless and wired. I need a WLAN adapter for the wireless part of the router. I get my Internet connection on my server through my wireless adapter from my host but it automatically sees it as an Ethernet adapter instead of as a wireless adapter. Is there any way of making a (virtual) wireless adapter on Ubuntu server 12.04 inside a hyper-v machine?

• Iptables port mapping from two PCs to one

  - by Anton

  We have 3 PCs, two of it are connected to internet (both of it have 2 NIC) PC1: eth0 - 1.0.0.1 (external IP) eth1 - 172.16.0.1 (internal IP) PC2: eth0 - 1.0.0.2 (external IP) eth1 - 172.16.0.2 (internal IP) PC3: eth0 - 172.16.0.3 (internal IP) Now we want to map port 80 from PC1 and PC2 to PC3. But there is the problem: iptables port forwarding works well from PC1 or PC2, but only in case if PC3 have PC1 or PC2 as gateway. So, question is: can we have port mapping from both PC1 and PC2 regardless of gateway settings on PC3? Thank you in advance.

• Remotely port forward/launch process or a client-less remote desktop app?

  - by DC177E

  I have an XP box running Logmein at a remote location behind a linksys router, which was running well for a whole of four days, until we had a power failure. Our ISP gave us a new IP, the machine restarted, and logmein did not autorun (or, at least, it did not automatically sign in), and our service (which may or may not be a Minecraft server with non-backed-up save files) also did not run upon startup. Logmein does not register the new IP (it still displays the old one). I have a DDNS updater service, so I do know the new dynamic address. I have tried using the built in XP remote desktop service, but, as with almost all non-cloud-based remote desktop services, it requires a port forward. Thus, I would appreciate it if anyone has any ideas as to: A: Any way of accessing our router remotely to forward the remote desktop port. I've seen the Remote Management option (forwarding the setup page to port 8080), but I do not have it enabled. I've tried UPnP, but again, the setup page for our router is not forwarded. B: Any way of remotely launching a process that does not require port forwarding (or uses ports 255XX, 18XXX, or 9000.), such as a remote console service built into XP. I realize this is a near impossibility. C: A Way to remotely start logmein, and sign in, which is likely a definite impossibility. Sorry if this is too specific for Stackexchange, or if I've put it into the wrong section (is SuperUser the correct place for this?). Ideas would, again be much appreciated, as shot-in-the-dark-like this may be.

• System Center 2012 R2 System Discovery Network Utilization

  - by AtomicReaction

  I'm in charge of a deployment of Microsoft System Center Configuration Manager 2012 R2. Currently, I'm working through the discovery methods and trying to decide how to enable automatic discovery of systems and users. On Microsoft's documentation, they warn that Configuration Manager Automatic Discovery traffic can get pretty significant if you aren't careful in your implementation. Can anyone who has used this give me some information on how much traffic I should expect? We currently have around 1000 computers and 4000 user accounts in Active Directory. Thanks!

• Giving Users Full Control of their local drives?

  - by Ian Bowes

  Is there a way to give a domain user full control of their local drives at the Group Policy end? Specifically, my IT Manager wants the following: a) Desktop control allowed b) Full access to local hard drives c) Software Installation NOT Allowed d) Existing software Updates Allowed e) Install additional printers Allowed At the moment, our Win2003 setup does not allow users to do a,b,d,e - I wondered if there was a way using GP to enable these?

• Folder Permissions in Windows 7

  - by gameshints

  I'm trying to securely share a folder across two computers on a relatively public network. However, I'm a bit confused on how permissions work and was hoping for some clarification between the following so I don't accidentally make something public I don't want. When you right-click a folder and go to properties, what is the difference between Sharing Tab - 'Share...' button - List of users and permissions there Sharing Tab - 'Advanced Sharing...' button - 'Permissions' button - List of users and permissions there Security Tab - List of users and permissions there Thanks!

• Can't Ping - Wireless network of home

  - by Naunidh

  Hello, This may seem like other ping problem, but I have tried a lot before posting it here. I have a linksys WRT54G - firmware v8.00.8. I have two laptops one windows vista (192.168.1.99) and Windows Xp (192.168.1.13) connected on WiFi . The Router's IP address is 192.168.1.4, and default gateway is the ADSL modem (192.168.1.1) connected through wire. The problem is that laptops can not ping each other, they can ping the gateway and the linksys router, and both can access internet. Following has been tried (I am pinging from XP machine to Vista): I saw that arp entires for Vista machines were not being populated, so I added static ARP entries. 192.168.1.99 00-19-7e-70-d0-4e static I checked on ethereal that an ICMP packet for MAC address of Vista machine does go out from XP machine towards the Vista machine, but never reaches the Vista machine. So its get eaten by the Router? I added Vista machine to DMZ in my linksys router, so that all the ports are open (In case it was an issue). Firewalls , antivirus etc were turned off, echo was enabled explicitly on vista, file sharing, network discovery were turned on. Network type was set to private. Unchecked everything in Router;s firewall, even though they are only meant for WAN requests. Is there anything else that I should try. Thanks.

• Mac | Router not assigning the IP address.

  - by Vaibhav Bajpai

  I recently installed Mac OS X 10.6, however the ethernet state is down. The assigned IP is 169.x.x.x. When booted the live USB of Ubuntu, I properly get an IP assigned in the range 192.168.1.x from the router 192.168.1.1 I am using the same router and same ethernet line. I tried to ping to 192.168.1.1 from my Mac and I get a host down message. I tried to manually assign the IP and set the router IP to 192.168.1.1 but still the router is unreachable.

• How do I connect my Windows XP laptop to the internet?

  - by rubysiddhi

  Hello fellow super users, The Past I have a Acer Travelmate 2300 laptop running Windows XP. 6 months ago I moved into a new apartment and got a new internet connection set up. After getting an internet connection installed in my apartment I reinstalled Windows XP and at the same time wiped my drive clean losing all the original Acer software and drivers. Once XP was reinstalled I had to find all the drivers again to get the Travelmate laptop connected to the internet. So, using my Vista laptop which was connected fine, I went to the Acer Travelmate Series drivers download page to download the necessary drivers. I transferred them to my Acer XP machine and installed them the best I could (there were no easy instructions so I just had to find all the executables and run them). I eventually got connected to the internet but not exactly in the way I had hoped for. The Present To be connected to the internet I need to have an Ethernet cord connecting my computer (via the Ethernet port) to my router. This is a problem since it defeats the purpose of having a Wireless LAN card in my Acer laptop. One of the programs I downloaded from the Acer Travelmate Series page was the Acer Wireless LAN Configuration Utility. This program allows me to see the current network I am connected to and all the available networks I could potentially connect to. It reminds me of XP's Wireless Network Connection window/utility where you can see all available wireless networks, refresh the network list and connect to one of the networks. I should mention that my ISP set up a security enabled wireless network with WPA. This network requires a network key if you want to connect to it. I guess my Vista computer has the network key entered into it already. The problem is that I do not know what the network key is. Now obviously you would say just contact my ISP to get the key. And I will but there is just one extra weird issue. I am able to connect to another unsecured wireless network in the Wireless Network Connection window/utility. I can be on it as long as my Ethernet cable is plugged in. So this is not really wireless is it? And this indicates that even if I do get that network key password from my ISP, I will only solve one of the two problems I have. I will only solve being able to get online as long as I am connected to my router via the Ethernet cable. The Main Questions So how do I enable my acer IPN2220 Wireless LAN Card so that I can use my Acer laptop from anywhere with in my apartment? Or should I first get the network key from my ISP to access my security enabled wireless network? And then deal with getting the acer IPN2220 Wireless LAN Card working? Hard & Learned VS Easy & Stupid Of course contacting the ISP would be easier. Have em just come in here and do there thing. The problem with that is that they do not speak English (yeah, im in Poland) and it'd be a hell of a time trying to understand what they are doing (uncomfortable looking over their shoulder). Also, I want to learn how to do this task myself so that I can fix the problem if it ever happens again. You know, be more self sufficient. I look forward to helpful replies. Thanks, Xaviour

• Keeping the wireless connected.

  - by casr

  I’m running OpenBSD on a computer which is connected via wireless to the network. It is a well supported NIC and I’ve had no problems with it from a hardware perspective. Unfortunately my wireless access point occasionally loves to forget it’s settings. I then have to help it remember. However, in this intervening time my OpenBSD box drops the connection and then does not automatically reconnect. I have alleviated my problems by running this simple script in the background: #!/bin/sh while [ 1 ] do ping -c1 192.168.1.254 > /dev/null if [ $? = 1 ] then sh /etc/netstart ral0 > /dev/null fi sleep 30 done [Ping the access point. If there is no response attempt to reconnect.] It seems to me to be a very suboptimal solution. Has anyone else come across a better way?

• Time Capsule + Ubee Router?

  - by Charlie

  I can't for the life of me figure this out. I recently had TWC installed in my house, and wanted to disable the NAT and router functions of it. I have a Time Capsule hooked up to it from LAN1 (on the Ubee) to the WAN port on the TC. The problems started occurring here. I figured the settings would be these: Ubee Configuration mode: Bridge DHCP: Off TC IPv4: 192.168.100.2 Subnet Mask: 255.255.255.0 Router Address: 192.168.100.1 DNS Servers: 8.8.8.8, 8.8.4.4 Router Mode: DHCP and NAT But using those settings, my TC says "Double NAT", so I have to change it all around to the default settings of the Ubee using NAT. This leads me to believe bridge mode doesn't actually turn off NAT...

• Selectively routing traffic via ethernet or wifi, with proper DNS (Mac OS X 10.6)

  - by Dan

  When I'm at work, I access various intranet pages as well as the wider Internet through ethernet. However, the company LAN blocks some ports (e.g. Google Calendar). I can get to those through WiFi. So, I gave the Airport priority, and then using route add, I set up selective routing: all intranet traffic goes through the ethernet and everything else via WiFi: sudo route add 10.0.0.0/8 <intranet gateway>. However, there are a number of intranet sites that have their own DNS; i.e., hr.company.com only resolves on the intranet. The only way that I can get the DNS to work properly is to add the internal DNS server to the Airport DNS listing, however I fear that when I go elsewhere and forget, this will break things. What's the right way to get the DNS to resolve using this setup?

• Sharing files between multiple computers?

  - by Koalatea

  At my school, we have 13 iMacs that we use to make our yearbook. Currently our school has some servers for us, but since we work with so many files ( thousands of pictures, most of which are ~3MB ) it slows down far too much. Is there a way to better share files between our computers? We are on a wireless network and the whole school shares the same servers, we have around probably 400 computers in the school. Is there a hardware fix I can do? Something like buying an external and hooking only yearbook computers to it?

• LMDE detects a wireless card, but can't use it

  - by Davidos

  LMDE can see my wireless card, and correctly identifies it, but it refuses to let me turn it on through the shiny graphical interface. Is there a way to use the non-shiny terminal to turn on my wireless? One small tidbit I noticed was the stated version; it says the version is 00. I believe that's hexadecimal for 0, which may indicate something screwy with the software. It would be nice if someone could tell me how to figure out how to solve this kind of problem in the future. *-network DISABLED description: Wireless interface product: Centrino Wireless-N 1000 vendor: Intel Corporation physical id: 0 bus info: pci@0000:09:00.0 logical name: wlan0 version: 00 serial: 91:e3:7b:0d:a3:a9 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlagn driverversion=3.0.0-1-amd64 firmware=39.31.5.1 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:43 memory:e1d00000-e1d01fff I've tested multiple other network managers, and none of them work.

• Remote Desktop connection breaks the wireless connection

  - by Michal Talaga

  When I connect to my Windows 8 Professional machine via Remote Desktop (RDP) I almost always get my WiFi connection broken. The setup: T61P Lenovo Laptop + W8 at home Wireless Router with NAT forwards connections to that machine Windows 7 laptop at work connecting to the home laptop When I connect, very often I get to login and suddenly connection is lost and I cannot reconnect again. When I get home I find my WiFi connection is still connected to the Access Point but does not function. Can't even ping the router. What is strange is that disabling wireless with the hardware switch and enabling it again doesn't help. The only way to make it works again: - Reboot - Disable wifi with hardware switch AND disable the network card in Device Manager, then enable both I did not have this problem on the very same laptop when it was running Windows 7. Any hint how can I find where the problem is?

• Service redirection on same network

  - by Unode

  I have a network on which I run multiple servers each dedicated to a given service. Because most services run on distinct ports I'm currently looking for a way of unifying "all" services into a single "proxy" machine. The idea is to abstract which machine is being accessed but still allow direct connection if needed/requested. This "proxy" machine has only one network interface which is part of the same network as all the other service providing machines. I've looked into Routing and NAT but I've so far failed to figure out how to make it work. I tried to achieve this using shorewall but couldn't find clear examples. However I'm not entirely sure this is the best/simplest strategy. With that said, what would be the best way of achieving this result? Example case: Proxy IP - Listening port - Send requests to 192.168.0.50 80 192.168.0.1:80 " 22 192.168.0.2:2222 " 3306 192.168.0.3:3000 " 5432 192.168.0.4:5432 " 5222 192.168.0.5:5222 PS: I'm not concerned with the single-point-of-failure nature of the proxy. Thanks

• How can I determine the IP addresses allocated by DHCP on a router that I'm connected to?

  - by user234831

  This "router" is not a typical situation. I'm using my phone as a hotspot and can only configure a select number of DHCP options. I can manage the limit on how many devices/clients can use my phone as a hotspot. I have to select from a radio-button list with the options: 2,3,4,5, or 8 I can specify the DHCP starting IP address. In this case, it begins at 192.168.6.106 When I'm connected via WIFI to my phone, an ipconfig /all command shows me that the default gateway is 192.168.6.1 and my IPv4 address is 192.168.1.148. I have the luxury of connecting another device to the phone and that device was assigned 192.168.1.121. I've tried connecting to 192.168.6.1, hoping for some sort of router setup page that I'm used to seeing, but there is no such thing or maybe it's just a matter of incompatable operating systems. In summary, the "router" (phone) has an IP address of 192.168.6.1 and a DHCP server that begins at 192.168.6.106 and allows up to 8 connections. Normally, I would assume a range of 192.168.6.106 - 192.168.6.113, but connected clients are showing otherwise. How can I figure out which IP addresses are set aside by DHCP for clients?

• Would a switch be covered by a router's firewall

  - by Uh-yeah...

  So... Hopefully; this is the right place for this question. I need more Ethernet ports on my home network. Sadly, we already have an old router connected to the main router and we still need more ports. I feel dumb for asking; but, I just would like to double check. Would the devices connected to the switch be "protected" by the Main router's firewall? ? Up to this point I have assumed that was the case; but, a co-worker is convinced that is not the case [ I believe he is thinking of a situation in which the switch (un-managed) is before an access point]. [It would go modem to main router; main router then has the switch and old router connected to it.

• Access server by hostname without domain

  - by projectshave

  I want to access services on other machines on my home network with just their hostname. In every browser, "http://machine" fails, but adding a period in "http://machine./" works. Is there a way to avoid adding that extra period? My setup is a router with DD-WRT w/ DNSmasq turned on, Win7 machines and several Ubuntu VMs. nslookup works fine with just hostname. Remote desktop works, but TightVNC needs the extra period. ssh needs the period. As I said, all my browsers need the extra period. I'd prefer a solution that doesn't require manually maintaining the hosts file. Thanks.

• Disable Network settings (TCP/IP & DNS) on Windows 7 Ultimate

  - by TiD91

  i also read this discussion here How to disable Tcp/Ip settings in windows 7 via GPO? about what i want to do but i still have problems. So here i am: i have a desktop pc with two accounts, both with Administrative rights. One is used by the entire my family, in particular by my brother. The problem is that i set some DNS and IP configurations to let be possible the VNC connection from remote. Now i would like to disable the network settings (TCP/IP and DNS) to prohibit my brother to change it preventing me to connect to it. So how can i do this? I set the policies from GPO but i still can change these settings from his account. Here's a pic of Registry Keys: http://imageshack.us/a/img339/3310/famigliapc2012092017274.png what didn't i do?

• Route outbound connections from local network through VPN

  - by Sharkos

  I have a server A running OpenVPN, an OpenVPN client B (a rooted Android phone as it happens) and a third party C (a laptop, tablet etc.) tethered to B. B can use the VPN to access the internet via A; C can use the tethered connection WITHOUT the VPN to access the internet via B. However, with the VPN on B active, I cannot load information from the internet on C. A appears to log similar traffic inbound and outbound when B or C attempt to load a webpage, say, but the VPN on device B reports no inbound traffic when the connection originated from C. Where should I look for packets being dropped, and what ip rules should I use to make sure they are passed back through the VPN and into the local network B <- C? (I'll obviously post whatever further information is needed.) Further info Without VPN: root@android:/ # ip route default via [B's External Gateway] dev rmnet0 [B's External Subnet] dev rmnet0 proto kernel scope link src [B's External IP] [B's External Gateway] dev rmnet0 scope link 192.168.43.0/24 dev wlan0 proto kernel scope link src 192.168.43.1 With VPN: root@android:/ # ip route 0.0.0.0/1 dev tun0 scope link default via [B's External Gateway] dev rmnet0 [B's External Subnet] dev rmnet0 proto kernel scope link src [B's External IP] [B's External Gateway] dev rmnet0 scope link [External address of A] dev tun0 scope link 128.0.0.0/1 dev tun0 scope link 172.16.0.0/24 dev tun0 scope link 172.16.0.8/30 dev tun0 proto kernel scope link src 172.16.0.10 192.168.43.0/24 dev wlan0 proto kernel scope link src 192.168.43.1 192.168.168.0/24 dev tun0 scope link
