• RDP or SSH connection trough Windows 2008 server VPN hang after a while

  - by xt4fs

  I have been experiencing a very strange issue with our VPN setup on Windows Server 2008. That server is running as a Xen Virtual Machine. We use it for two purposes, permit our mobile workers to connect to another server hosted somewhere else that only allow that ip, and use it to RDP or ssh to many other virtual machine on the same server. The server has no performance issue and still a load of memory free. All other virtual machine has no problem whatsoever. Many of those virtual machine have public IP (web servers) and all their firewall are set to allow only ssh connection or RDP connection from their local interface. When I am connecting directly with either ssh or RDP to one of the other virtual machine everything run without any issues. However, when I am doing so through the VPN after some time the connection just hang, it usually continue after some time (5 or 10 minutes). It seems as more there is network usage more often it happen to a point where it is completely unusable. The worst thing I can do to hang it faster is to actually ping the vpn client IP from the local network, after some time the latency increase until it hang. This happen even if I do RDP to the local ip of the VPN server trough the VPN. The server report no problem and if I disconnect to the vpn and reconnect right away everything is alright. There is nothing wrong in the VPN server log. I have taught at the beginning that it could have been an issue with the Host server so I try to RDP,ssh directly to the guest and I have experience no issue while doing this, so it really seems to be a problem with the VPN server on Windows server 2008. Another very weird thing is it does not seems to be of any issue if you only do Internet (NAT) without trying to connect to any local ips.

• Connection refused in ssh tunnel to apache forward proxy setup

  - by arkascha

  I am trying to setup a private forward proxy in a small server. I mean to use it during a conference to tunnel my internet access through an ssh tunnel to the proxy server. So I created a virtual host inside apache-2.2 running the proxy, the proxy_http and the proxy_connect module. I use this configuration: <VirtualHost localhost:8080> ServerAdmin xxxxxxxxxxxxxxxxxxxx ServerName yyyyyyyyyyyyyyyyyyyy ErrorLog /var/log/apache2/proxy-error_log CustomLog /var/log/apache2/proxy-access_log combined <IfModule mod_proxy.c> ProxyRequests On <Proxy *> # deny access to all IP addresses except localhost Order deny,allow Deny from all Allow from 127.0.0.1 </Proxy> # The following is my preference. Your mileage may vary. ProxyVia Block ## allow SSL proxy AllowCONNECT 443 </IfModule> </VirtualHost> After restarting apache I create a tunnel from client to server: #> ssh -L8080:localhost:8080 <server address> and try to access the internet through that tunnel: #> links -http-proxy localhost:8080 http://www.linux.org I would expect to see the requested page. Instead a get a "connection refused" error. In the shell holding open the ssh tunnel I get this: channel 3: open failed: connect failed: Connection refused Anyone got an idea why this connection is refused ?

• ssh_exchange_identification: Connection closed by remote host

  - by rick

  Firstly, I know that this question has been asked a million times, and I have read everything I can find and still cannot fix the problem. i am encountering this issue when ssh'ing in from my mac to my Ubuntu server on a fresh install of Ubuntu (I reinstalled because of this issue). I have SSH portmapped to 7070 because my ISP is blocking 22. On the client: bash: ssh -p 7070 -v [email protected] debug1: Reading configuration data /etc/ssh_config debug1: Connecting to address.org port 7070. debug1: Connection established. debug1: identity file /home/me/.ssh/identity type -1 debug1: identity file /home/me/.ssh/id_rsa type 1 debug1: identity file /home/me/.ssh/id_dsa type -1 ssh_exchange_identification: Connection closed by remote host Here's what I have done to try to resolve the issue: Made sure my maxstartups is ok: bash: grep MaxStartups /etc/ssh/sshd_config #MaxStartups 10:30:60 Made sure hosts.deny is clear of denials. Made sure hosts.allow has my client IP. Clear out known_hosts on client Changed ownership of /var/run to root Made sure etc/run/ssh is Made sure /var/empty exists Reinstall openssh-server Reinstall ubuntu When I run telnet localhost, I get this: telnet localhost Trying ::1... Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused When I run /usr/sbin/sshd -t Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_dsa_key When I regenerate the keys with ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key I get the same error. I am pretty sure this is the issue. Can anyone help?

• Private IP getting routed over Internet

  - by WernerCD

  We are setting up an internal program, on an internal server that uses the private 172.30.x.x subnet... when we ping the address 172.30.138.2, it routes across the internet: C:\>tracert 172.30.138.2 Tracing route to 172.30.138.2 over a maximum of 30 hops 1 6 ms 1 ms 1 ms xxxx.xxxxxxxxxxxxxxx.org [192.168.28.1] 2 * * * Request timed out. 3 12 ms 13 ms 9 ms xxxxxxxxxxx.xxxxxx.xx.xxx.xxxxxxx.net [68.85.xx.xx] 4 15 ms 11 ms 55 ms te-7-3-ar01.salisbury.md.bad.comcast.net [68.87.xx.xx] 5 13 ms 14 ms 18 ms xe-11-0-3-0-ar04.capitolhghts.md.bad.comcast.net [68.85.xx.xx] 6 19 ms 18 ms 14 ms te-1-0-0-4-cr01.denver.co.ibone.comcast.net [68.86.xx.xx] 7 28 ms 30 ms 30 ms pos-4-12-0-0-cr01.atlanta.ga.ibone.comcast.net [68.86.xx.xx] 8 30 ms 43 ms 30 ms 68.86.xx.xx 9 30 ms 29 ms 31 ms 172.30.138.2 Trace complete. This has a number of us confused. If we had a VPN setup, it wouldn't show up as being routed across the internet. If it hit an internet server, Private IP's (such as 192.168) shouldn't get routed. What would let a private IP address get routed across servers? would the fact that it's all comcast mean that they have their routers setup wrong?

• Vyatta internet connection + hosted site on same IP

  - by boburob

  Having a small issue setting up a vyatta. The company internet and two different websites are both on the same IP. Server 1 - Has websites hosted on ports 1000 and 3000 and also has a proxy server installed to provide internet connection to the domain Server 2 - Has a website hosted on ports 80 and 433 The vyatta is correctly natting the appropriate traffic to each server, and allowing the proxy to get internet traffic, however I have a problem getting to the websites hosted on these two servers inside the domain. I believe the problem is that the HTTP request is being sent with an IP, eg: 12.34.56.78. The request will reach the website and the server will attempt to send the request back to the IP, however this is the IP of the Vyatta, so it has nowhere else to go. I thought the solution would be something like this: rule 50 { destination { address 12.34.56.78 port 1000 } inbound-interface eth1 inside-address { address 10.19.2.3 } protocol tcp type destination } But this doesnt seem to do it! UPDATE I changed the rules to the following: rule 50 { destination { address 12.34.56.78 port 443 } outbound-interface eth1 protocol tcp source { address 10.19.2.3 } type masquerade } rule 51 { destination { address 12.34.56.78 port 443 } inbound-interface eth1 inside-address { address 10.19.2.2 } protocol tcp type destination } I am now seeing traffic going between the two with Wireshark, but the website will still fail to load.

• D-Link DWA-125 constantly disconnecting in winXP, but works fine on ubuntu..

  - by sil3nt

  Hey there, I'm dual booting winXp and ubuntu 10.10. I'm using a DWA-125 usb adapter to connect to my home wifi connection and I'm having this odd issue. First off, in ubuntu the adapter works fine and I have no trouble at all, but when I boot back in XP I get a dlink connetion wizard and the connection times out after every 2 minutes. It's odd because I can actually load up web pages and use the internet for 2 minutes, and then it would disconnect and the whole thing would repeat. I did a system restore on xp and this stopped the whole connect-disconnect thing but once I booted into ubuntu and came back to xp it started all over again!(?). Any ideas as to how I would go about fixing this?

• Resolving loss of internet bandwidth in home network

  - by Caspar

  Recently, I've decided to connect my laptop at home to my modem/router through Ethernet cables built into my apartment. As these built-in Ethernet cables are usable via plugs built into the walls (called powerline adapters), I use some additional cabling (STP CAT6 cables) from my laptop/router to the plugs. In addition, I don't know any technical details about these built-in cables (as they're not visible), only the maximal bandwidth (1 GBit = Cat6?) that they're supporting. The built-in cables are Cat. 5e Ethernet cables. The problem is now that when I set up the connection, I cannot use the full bandwidth that my internet connection is actually offering (100 Mbit/s), only about 85 Mbit/s between 85 - 88 Mbit/s, despite the fact that all cables involved should support the maximal bandwidth. I know from other tests with one of the Ethernet cables in use that I can use almost 99 Mbit/s when I connect my laptop directly to the router/modem using only this one cable. In addition, it is very unlikely that the length of the resulting cable connection from my laptop to my router involving the built-in cables exceeds 100 m. So, what possible reasons for this loss of bandwidth exist? And how I can fix this issue? I hope this might help resolve the issue: The built-in cables appear to be Cat. 5e Ethernet cables. So, is there any problem when I connect Cat6 Ethernet cables directly to Cat5e Ethernet cables via the plugs?

• Laptop connects to other network but not to my home wireless

  - by Nilesh

  My home network's wireless SSID is say "XYZ" I also have an ethernet wire from the same router. I have two laptops A and B Earlier both A and B were able to connect to my home internet through the ethernet and wireless. Suddenly, the laptop B can no longer connect to XYZ or through ethernet. When I do plug the wire, i get the connection icon all green but when I try to access any web page it errors out (page not found) But strangely laptop B connects to my neighbours wireless SSID "ABC". I have also tested laptop B with other networks and it connects fine. Laptop A and many other devices still connect fine with my home wireless "XYZ" Strange thing is when my laptop B connects wireless through XYz, it gets the IP address but then none of the browsers (chrome,firefox, IE) can show any web pages. What settings should I be checking on laptop B that is preventing it to connect to my home internet. Thank you

• Software to measure the speed of http browser connections

  - by Dan Revell

  I'm trying to gather some ammunition about my ISP and it's aggressive traffic shaping of particular websites. So I'm looking for an application that will allow me to see what speeds I get to particular websites. I want to open a browser connection to a particular video streaming website for example and see the speed of the connection that gets made, be it http or plain tcp. I'm after something along the lines of TCPView but unfortunately this doesn't include transfer speeds. I'm half tempted to write one myself but hopefully something will already be out there that does the job.

• Windows VPN for remote site connection drawbacks

  - by Damo

  I'm looking for some thoughts on a particular way of setting up a estate of machines. We have a requirement to install machines into unmanned, remote locations. These machines will auto login and perform tasks controlled from a central server. In order to manage patching, AV, updates etc I want these machines to be joined to a dedicated domain for this estate. Some of the locations will only have 3G connectivity (via other hardware), others will be located on customer premises in internal networks. The central server (of ours) and the Domain Controller will be on a public WAN. I see two ways of facilitating this. Install a router at each location and have a site to site VPN between the remove device and the data centre where the servers are location Have the remote machine dial up and authenticate via a Windows VPN connection to the DC via RAS Option one is more costly to setup and has a higher operational cost. It also offers better diagnostics if the remote PC goes down. Option two works well but is solely dependent on the VPN connection been made before any communication can be made to the remote machine. In a simple test, I can got a Windows 7 machine to dial a VPN prior to authentication to a domain, then automatically login to the machine using domain credentials. If the VPN connection drops, it redials. I can also create a timed task to auto connect every hour in case of other issues. I'd like to know, why (if at all) is operating a remote network of devices which are located in various out of band locations in this way a bad idea? Consider 300-400 remote machines all at different sites. I'd rather have 400 VPN connections to a 2008 server than 400 routers, however I'd like to know other opinions on this.

• how to set up dual wireless routers (G and N) with single broadband connection

  - by user15973

  A local cafe has an 802.11g wireless router attached to either an 8- or 12Mbs broadband connection. Although many customers still have -g devices, an increasing number are showing up with 802.11n devices (e.g. Mac laptops, iPads). The cafe owner is content with his router's area coverage, but he would like for his customers to be able to take advantage of the higher -n download speeds. He could simply replace the -g router with a -n router, but reportedly -n routers slow down considerably when servicing both -g and -n connections. Another option would be to buy the -n router, run an Ethernet cable between the two routers, and (of course) hook up the broadband connection to one of the two routers. Still another option would be to attach an ordinary, wired switch to the broadband connection and then attach both routers to the switch. Aside from the cost issue, what are the tradeoffs of those approaches? Which would you recommend, and why? Is there a better option than the ones I mentioned? Thank you in advance for your advice.

• Why can't European users access my site?

  - by japancheese

  Hello, My site has been running just fine for the past couple of years, but all of a sudden, two days ago, European users have been experiencing serious connection problems to the site. I really want to fix this for them, but what's the best way to figure out what the issue is? I have absolutely no connection problems to the site on my end, nor do Asian or other American users it seems. Using just-ping.com, some European servers come back with some packet losses. I tried doing some traceroutes from European servers to my own, but they all seemed to work just fine. I'd at least like to be able to tell users that if the problem does not lie with my server, then it at least lies somewhere out of my control. I really want to figure out what the choke point is though. Is there another way I might be able to find out why they can't seem to connect to the site? Just looking for any other ideas from people that have had a similar experience.

• Internet Troubles - PPPoE vs PPPoA?

  - by AkkA

  I have been having some internet troubles at home (ADSL2+ connection in Australia). We get random drop-outs from the authentication connection. It will keep the connection to the DSL service, but we lose authentication and either have to restart the router/modem (its combined, a Belkin one, not sure on model number) or unplug the phone cable, wait about 30 seconds and plug it in again. I've called the ISP (Telstra) a few times, but they only offer limited support when we dont use their supported hardware. Apparently something had happened on their side, they checked the box again (at least it sounded that simple), and told me it would be fine. It wasnt. I've replaced all the filters around the house, but that didnt help either. We do live a little bit away from the exchange (get a sync speed of about 3000/900), so I thought it could be due to line noise but that hasnt helped. Telstra allow both PPPoE and PPPoA connections (which I'm configuring through my router, dont have software on the PC side). I've been running PPPoA the whole time, would it make any difference changing it to PPPoE? If not, are there any other theories as to why we would be experiencing these drop-outs? It has been fine for at least 12 months, then suddenly started about 2 months ago.

• then an error occurred during the login process - Connection Error 233

  - by scott brunner

  We have SQL Server 2008 installed on 64Bit Windows Server 2003. When we try connect to the local SQL Server using SQL Server Management Studio at the console, we get the error: A connection was successfully established with the server, but then an error occurred during the login process. provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe. When we try TCP from same local SSMS to local server, we get the same error but intead of the pipe message its something like "connection forcibly closed". Now, here is the strange part - we CAN connect to this SQL Server from any other machine on the network using SSMS. - AND - WE CAN'T connect to ANY SQL Server from the problem server. So it seems the SQL Server instance is fine and accepting remote connections. However, the SSMS on that machine will not connect to any SQL Server even remotely. When we try an ADO.NET connection from C# remotely we can connect, run that same code on the console of the trouble server and we get the same errors. How can this be solved?

• SSH Connection Error : No route to host

  - by dewbot

  There are three machines in this scenario: Desktop A : [email protected] Laptop A : [email protected] Machine B : [email protected] All the machines have Ubuntu 11.04 (Desktop A is a 64bit one) and have both openssh-server and openssh-client. Now when I try to connect Desktop A to Laptop A or vice-versa by ssh [email protected] I get an error as port 22: No route to host in both the cases. I own both the machines, now if I try same commands from my friend's machine, i.e. via Desktop B, I can access both my Laptop and Desktop. But if I try to access Desktop B from my Laptop or by Desktop I get port 22: Connection timed out I even tried changing ssh port no. in ssh_config file but no success. Note: that 'Laptop A' uses WiFi connection while 'Machine A' uses Ethernet Connection and 'Machine B' is on an entirely different network. Laptop A && Desktop A - Router/Nano_Rcvr provided to me by ISP. So to one Router two Machines are connected and can be accessed at the same time. here is my ifconfig output for both the machines :- Laptop wlan0 Link encap:Ethernet HWaddr X:X:X:X:00:bc inet addr:1.23.73.111 Bcast:1.23.95.255 Mask:255.255.224.0 inet6 addr: fe80::219:e3ff:fe04:bc/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:108409 errors:0 dropped:0 overruns:0 frame:0 TX packets:82523 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:44974080 (44.9 MB) TX bytes:22973031 (22.9 MB) Desktop eth0 Link encap:Ethernet HWaddr X:X:X:X:c5:78 inet addr:1.23.68.209 Bcast:1.23.95.255 Mask:255.255.224.0 inet6 addr: fe80::227:eff:fe04:c578/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:10380 errors:0 dropped:0 overruns:0 frame:0 TX packets:4509 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1790366 (1.7 MB) TX bytes:852877 (852.8 KB) Interrupt:43 Base address:0x2000

• Ubuntu - wireless connection works great but wired is totally dead

  - by Dan

  I am running Ubuntu 10.04 on my Acer Aspire One netbook. The wireless connection works great, but the wired is totally dead. When I plug the Ethernet wire, the little led next to the port doesn't blink. If I do ifconfig, this is the output: lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1659 errors:0 dropped:0 overruns:0 frame:0 TX packets:1659 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:132304 (132.3 KB) TX bytes:132304 (132.3 KB) wlan0 Link encap:Ethernet HWaddr 18:f4:6a:65:48:1f inet addr:192.168.1.7 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::1af4:6aff:fe65:481f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:94823 errors:0 dropped:0 overruns:0 frame:0 TX packets:81390 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:93028474 (93.0 MB) TX bytes:18002558 (18.0 MB) There is no eth0. Is that normal? In the "Network Connections" GUI there is an entry "Wired connection 1", its "MAC address" field is blank. How can I make the wired connection work?

• Why can't I connect to a wifi network with my laptop, when I can with my phone?

  - by Alex Sf.

  I can connect with my phone and use the browser as usual. On my laptop it won't connect when using windows 7 while in ubuntu it will connect, but with no internet. What is going on here and how can I get internet on my laptop ? [edit] It's a public wifi hotspot. I can connect with no issues at home. My network asapter is: Atheros AR5B97. And my phone is an iPhone 3G. The wizard's of no help since it asks me to check the router, which I can't since it's a public hostspot.

• Motorola Surfboard SB6121 modem conected to 2WIREi38HG wireless router but there's no internet access

  - by Jessica

  I have just switched to Comcast cable internet from AT&T Uverse and I was hoping to use the 2WIRE wireless router with the new Surfboard modem so I can have wireless access. I messed around with some settings and got it working for my laptop (I'm not terribly well versed in computer stuff; I think it was mostly luck) for about a week. The other day I tried to get online and there was no internet connection. I restarted the equipment with no success and then plugged the modem directly into the laptop. This worked, so I knew there was no outage. I connected the ethernet cord to the router and a second cord to my laptop and that worked, too. But when I tried again just with the wireless the laptop connects to the router, but doesn't recognize it or find an internet connection. I tried to go to http://gateway.2Wire.net to fiddle with the settings, but all I get is a Server Not Found page. I tried to check the ip address but this is really kind of over my head and I get different things checking it while plugged into only the modem vs when I plug into the router. Can anyone help? The frustrating thing is that I had it working for awhile, so I know it can do it!

• Issue with SSH on Ubuntu - Local connection ok, remote connection - Is it me or my ISP?

  - by Benjamin

  I have an issue with a server running Ubuntu 12.04, I am trying to set up a remote connection so I can access the server at my work from out of town. I have installed the SSH server and all that stuff, and I have reassigned the default port from 22 to 3399. A local connection from any OS can connect on the 192.168... address, but in no way can I get a connection on the actual IP address. I believe my configuration is correct, and I will attach it. If I have done something wrong in the config, please tell me and I will make a change to it. I honestly think that the Router that my ISP provided is horrible, and although the port for ssh is forwarded, it might be stopping any traffic coming inbound. Is there anything I can try to verify this? /var/log/auth does not show any error when I connect VIA our static IP. I have included all values not commented out below: (sshd_config) Port 3399 ListenAddress 0.0.0.0 Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key HostKey /etc/ssh/ssh_host_ecdsa_key UsePrivilegeSeparation yes KeyRegenerationInterval 3600 ServerKeyBits 768 SyslogFacility AUTH LogLevel INFO LoginGraceTime 120 PermitRootLogin yes StrictModes yes UseDNS no RSAAuthentication yes IgnoreRhosts yes RhostsRSAAuthentication no HostbasedAuthentication no PermitEmptyPasswords no ChallengeResponseAuthentication no PasswordAuthentication yes GSSAPIAuthentication no X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes AcceptEnv LANG LC_* Subsystem sftp /usr/lib/openssh/sftp-server UsePAM yes Am I doing this wrong? port forwarding image

• Mapped network drive connection timeout

  - by Terix

  I have server "Alpha" and server "Beta". Server Beta has a shared folder, that is mapped on server Alpha as "X:" On server Alpha there is a .vbs script that runs and take some files on local drive and copy them on X: drive. My issue is if no user log on server Alpha for a long time, it seems like the tcp connection underneath the mapped drive has a timeout, and the vbs script fails on the copy of file. As soon I log with remote desktop on Alpha server, the .vbs is successfull on the copy of the files. I have made many tests, using file logs to check what was happening and I found no way to refresh the connection and let the .vbs be able to copy files unattended.. I have always to log with remote desktop on Alpha server to refresh the connection and let the .vbs copy the files without issues. What can I do to avoid to log every time? The .vbs script runs 3 times a day and is very annoying. I do not have control over server Beta so I cannot change anything there, and I am very limited on changes I can do on server Alpha ( I cannot change registry and that sort of things)
