  • What's wrong with this HTTP POST request?

    - by bigboy
    I'm trying to fuzz a server using the Sulley fuzzing framework. I observe the following stream in Wireshark. The error talks about a problem with JSON parsing, however, when I try the same HTTP POST request using Google Chrome's Postman extension, it succeeds. Can anyone please explain what could be wrong about this HTTP POST request? The JSON seems valid. POST /restconf/config HTTP/1.1 Host: 127.0.0.1:8080 Accept: */* Content-Type: application/yang.data+json { "toaster:toaster" : { "toaster:toasterManufacturer" : "Geqq", "toaster:toasterModelNumber" : "asaxc", "toaster:toasterStatus" : "_." }} HTTP/1.1 400 Bad Request Server: Apache-Coyote/1.1 Content-Type: */* Transfer-Encoding: chunked Date: Sat, 07 Jun 2014 05:26:35 GMT Connection: close 152 <?xml version="1.0" encoding="UTF-8" standalone="no"?> <errors xmlns="urn:ietf:params:xml:ns:yang:ietf-restconf"> <error> <error-type>protocol</error-type> <error-tag>malformed-message</error-tag> <error-message>Error parsing input: Root element of Json has to be Object</error-message> </error> </errors> 0

  • Windows Vista claims wireless key is the wrong length

    - by humble coffee
    A family member of mine is house sitting and has been given the details of their wifi. The access point is an Airport Express, it has WEP encryption (I think) and they've been given a passphrase to use. I know it's a passphrase and not the encrypted key as it's an English word. The passphrase is 10 characters long. The problem is that Vista complains that it's not a valid key as it must be a 5 or 13 character non-hex key or a 10 or 26 character hex key. (From what I've read this suggests the encryption is WEP?) I've found a couple of suggested solutions, but I'm not actually at the house at the moment so I wanted to make sure I have a good chance of getting it to work when I'm there but have no internets to ask. Solution 1: Vista needs to be told explicitly what kind of encryption and key is being used. Specify in the connection settings that you are using WEP and that it is a "shared key". Solution2: Try converting the passphrase to hexadecimal using an ASCII-hex converter and entering that.

  • Edit-text-files-over-SSH using a local text editor

    - by Mikko Ohtamaa
    I am working in various Linux and UNIX environments. I'd like to elegantly solve the problem of editing remote configuration files over SSH. Instead of using terminal editors (nano), I'd like to open the file in a local text editor on my desktop (Sublime Text 2). CyberDuck, WinSCP and various other SFTP apps can do this. Using editors over X11 forwarding has also proven to be problematic. Also using archaic text editors like Vim or Emacs do not serve my needs well. They could do this, but I prefer using other text editing software. Using ssh mounts (FUSE) are also problematic unless they can happen on the demand and triggered by the remote site. So what I hope to achieve Have a somekind of easily deployable shell script etc. which I can copy to remote server (let's call it mooedit) I run mooedit command on the remote server of which I have connected over SSH connection mooedit sends some kind of signal (over SSH( to my local desktop On my local desktop this signal is captured and it determines 'a ha! moo wants to edit a file on server X in folder Y' File is SFTP transfered to the local desktop (/tmp) File is opened in a nice GUI text editor on the local desktop When Save is pressed, the local desktop notices changes in the file and SFTP sends the resulting file back to the server The question is: What signaling mechanisms SSH provides for this? Any other methods to trigger a local text editor for remote SSH file?

  • OpenVPN: ifup tap0 drops all connections

    - by raspi
    I'm trying to create star shaped "virtual" LAN with OpenVPN which is not connected to physical network. ie. tap0 packets should not go to eth0. Packet should only go through OpenVPN to connected clients. This setup works with my OpenVPN testing machine which runs Virtual Box but not on my actual server which is running on top of Xen. Both servers are running Ubuntu Intrepid. /etc/network/interfaces: iface tap0 inet manual address 10.10.10.1 netmask 255.255.255.0 gateway 10.10.10.1 /etc/openvpn/server.conf mode server tls-server port 1194 proto udp dev tap client-to-client ca /etc/openvpn/easy-rsa/keys/ca.crt cert /etc/openvpn/easy-rsa/keys/servername.crt key /etc/openvpn/easy-rsa/keys/servername.key dh /etc/openvpn/easy-rsa/keys/dh384.pem ifconfig-pool-persist ipp.txt server-bridge 10.10.10.1 255.255.255.0 10.10.10.128 10.10.10.250 push .route 10.10.10.1 255.255.255.0 keepalive 5 60 comp-lzo persist-key persist-tun status /var/log/openvpn-status.log log-append /var/log/openvpn.log verb 3 user nobody group nogroup ifup tap0 on Virtual Box: everything ok, SSH keeps running.

  • How to troubleshoot problem with OpenVpn Appliance Server not able to connect

    - by Peter
    1) I have a Windows Server 2008 Standard SP2 2) I am running Hyper-V and have the OpenSvn Appliance Server virtual running 3) I have configured it as it said, only issue was that the legacy network adapter does not have a setting the instructions mention "Enable spoofing of MAC Addresses". My understand is that before R2, this was on by default. 4) Server is running, web interfaces look good 5) I am trying to connect from a Vista 64 box and cannot 5a) If I set to UPD I am stuck at Authorizing and client log looks like: 10/11/09 15:00:42: INFO: OvpnConfig: connect... 10/11/09 15:00:42: INFO: Gui listen socket at 34567 10/11/09 15:00:42: INFO: sending start command to instantiator... 10/11/09 15:00:42: INFO: start 34567 ?C:\Users\Peter\AppData\Roaming\OpenVPNTech\config?02369512D0C82A04B88093022DA0226202218022A902264022AE022B? 10/11/09 15:00:42: INFO: Got line from MI->>INFO:OpenVPN Management Interface Version 1 -- type 'help' for more info 10/11/09 15:00:42: INFO: Got line from MI->>HOLD:Waiting for hold release 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: real-time state notification set to ON 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: bytecount interval changed 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: hold flag set to OFF 10/11/09 15:00:43: INFO: Got line from MI->SUCCESS: hold release succeeded 10/11/09 15:00:43: INFO: Got line from MI->>PASSWORD:Need 'Auth' username/password 10/11/09 15:00:43: INFO: Processing PASSWORD. 10/11/09 15:00:43: INFO: OvpnClient: setting need auth to true. 10/11/09 15:00:43: INFO: OvpnConfig: Setting need auth to true. 10/11/09 15:00:43: INFO: Got auth request from active_config from 0 10/11/09 15:00:47: INFO: Sending Credentials.... 10/11/09 15:00:47: INFO: Sending 25 bytes for username. 10/11/09 15:00:47: INFO: Sent 25 bytes for username. 10/11/09 15:00:47: INFO: Sending 30 bytes for password. 10/11/09 15:00:47: INFO: Sent 30 bytes for password. 10/11/09 15:00:48: INFO: Got line from MI->SUCCESS: 'Auth' username entered, but not yet verified 10/11/09 15:00:48: INFO: Got line from MI->SUCCESS: 'Auth' password entered, but not yet verified 10/11/09 15:00:48: INFO: Got line from MI->>STATE:1255287647,WAIT,,, 10/11/09 15:00:48: INFO: Got line from MI->>BYTECOUNT:0,42 10/11/09 15:00:48: INFO: Got line from MI->>BYTECOUNT:54,42 10/11/09 15:00:48: INFO: Got line from MI->>STATE:1255287648,AUTH,,, 10/11/09 15:00:50: INFO: Got line from MI->>BYTECOUNT:2560,2868 10/11/09 15:00:52: INFO: Got line from MI->>BYTECOUNT:2560,3378 5b) I setup server for tcp and try to connect, I get a loop of authorizing and reconnecting.

  • Database mirroring login failure attempts on mirror server

    - by Chandan
    I have configured database mirroring between two servers at a distance 40 miles away from each other. Server specifications: SQL Server 2008,Standard Edition 64-bit This is same for principal,mirror and witness. The configuration is high-safety with automatic failover Initially we tested our .net application(web application) on both the principal and mirror and made sure that the login is not orpahned. Things run fine generally.But sometimes on the mirror server,I see login failed attempts: Login failed for user 'd0main\user'. Reason: Failed to open the explicitly specified database. [CLIENT: xx.xx.x.x] Message Error: 18456, Severity: 14, State: 38. This error appears 3-4 times a day but not more than that. My question to the experts is:If the principal is alive so why the application tries to connect to mirror.The default time-out for a .net webpage is 30 seconds,so is it possible that the application tries to connect principal and after 30 seconds even if principal is alive,it assumes that it is dead and thus tries to open a connection to mirror where it fails. Please help me with this problem.

  • OpenVPN, install a TAP adapter

    - by GolezTrol
    When I try to connect to my work VPN using OpenVPN, the connection fails with the message: All TAP-Win32 adapters on this system are currently in use. Many sources suggest to look in Control Panel\Network and Internet\Network Connections an enable the TAP adapter, but when I look there, there is none. Now I've run addtap.bat which is provided with OpenVPN, but I still don't get to see any TAP adapter, and logging in in VPN still fails. The output of addtap.bat is C:\Windows\system32>"C:\Program Files (x86)\OpenVPN\bin\tapinstall.exe" install "C:\Program Files (x86)\OpenVPN\driver\OemWin2k.inf" tap0801 Device node created. Install is complete when drivers are updated... Updating drivers for tap0801 from C:\Program Files (x86)\OpenVPN\driver\OemWin2k .inf. Drivers updated successfully. I've Run As Administrator both the setup of OpenVPN and addtap.bat. I've run deltapall.bat to remove any (maybe hidden) adapters. It said it removed three of them, after which I ran addtap.bat again to try to create another one. I also run OpenVPN itself as administrator. What's wrong? Running Windows 7 Home Premium on a HP Pavilion dv7 4050ed. It has worked before, but I recently had to reinstall my laptop, for which I used the restore disks I created when I just got it. Everything else seems to work fine. == UPDATE == The TAP adapter is found in Device Manager, but apparently it is disabled because it is incompatible with Windows 7 64bit. I've deïnstalled OpenVPNGui, downloaded a version that should be 64bit compatible, and installed that. Still no cigar. Then I found a tip to install OpenVPN (version 9) after installing OpenVPNGui, because that installs OpenVPN version 8. Now I got a v9 TAP driver in Device Manager, but it still doesn't work and shows up in device manager with an exclamation mark, and not at all in my network devices.

  • eXist-db: can't start webstart client on a closed port, reverse proxied via apache

    - by rvdb
    I am configuring an Apache HTTP server so it reverse proxies requests starting with /app/ to an eXist-db instance running in a Tomcat server, on port 8082. This port has been closed in the firewall and is inaccessible to the outer world. Following the eXist documentation, I have following rules in place in my httpd.conf file: ProxyPass /apps/ http://localhost:8082/ ProxyPassReverse /apps/ http://localhost:8082/ ProxyPassReverseCookiePath /apps/ / All goes well for requests to e.g. 'http://mydomain/apps/exist/index.xml'. Yet, the webstart client (accessible at 'http://localhost:8082/exist/webstart/exist.jnlp' on the web server) doesn't work behind the proxy. While 'http://mydomain/apps/exist/webstart/exist.jnlp' does generate a valid exist.jnlp file, that file can't be executed. The reason seems quite obvious: apparently, the eXist-db instance generating the exist.jnlp file only sees the proxied request as: 'http://localhost:8082/exist/webstart/exist.jnlp'. Yet, since the exist.jnlp file is executed on the client, that reference is meaningless (unless the client computer happens to have an eXist-db instance running on that port). Executing the exist.jnlp file hence fails with a 'connection refused' error. Yet, there's no problem at all connecting a local eXist-db Java client to the proxied eXist instance with the URL xmldb:exist://mydomain/apps/exist/xmlrpc. The problem lies in generating the webstart exist.jnlp file, which seems to need access to a publicly accessible URL. However, opening port 8082 and replacing the Proxy references to 'http://localhost:8082' with 'http://mydomain:8082' IMO rather destroys the point of reverse proxying. Do others have had success reverse proxying eXist-db on a closed port behind Apache? Are there perhaps some Proxy configuration settings I have overlooked (I'm no expert at all) that can make eXist see the original request instead of the proxied one? Kind regards, Ron

  • 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.

  • Trouble with IIS SMTP relaying to Gmail

    - by saille
    I appreciate that similar questions have been asked about how to setup SMTP relaying with IIS's virtual SMTP server. However I'm still completely stumped on this problem. Here's the setup: IIS 6.0 SMTP server running on Win2k3 box with a NAT'ed IP. Company uses Gmail for all email services. An app on the box needs to send email, so normally we'd just set the app up to talk to smtp.gmail.com directly, but this app doesn't support TLS. Easy, we just setup a local SMTP relay right? So I thought. What we have done so far: Setup IIS SMTP server to relay to smtp.gmail.com, as per these excellent instructions: http://fmuntean.wordpress.com/2008/10/26/how-to-configure-iis-smtp-server-to-forward-emails-using-a-gmail-account/ The local SMTP relay allows anonymous access. Both the local IP and the loopback IP have been explicitly allowed in the Connection and Relay dialogs. Tried sending email from 2 different apps via the local SMTP server, but failed (the emails end up in the Queue folder, but never get sent). The IIS logs show the conversation with the local app, but zero conversation happening with smtp.gmail.com. The port used by gmail is open outbound, and indeed the apps we have that support TLS can send email directly via smtp.gmail.com, so there is no problem with the network. At this point I changed the smtp settings in IIS SMTP server to use a different external SMTP server and hey-presto, the local apps can send email via local IIS SMTP relay. So smtp.gmail.com fails to work with our IIS SMTP relay, but another 3rd party SMTP service works fine. We need to use smtp.gmail.com, so how to troubleshoot this one?

  • Do all routers really must know all routes to every router?

    - by Philipili
    This is my complicated and long question. First let's talk about the context. Network topology: PC A --- RT A --- RT C --- RT B --- PC B (RT C has a WAN NIC connected to "the cloud") With this situation : PC A must send a packet to PC B Default routes direct packets to the cloud We haven't access to RT C's configuration RT C only knows how to join network A, not network B RT A knows about network B RT B knows about network A RT C's routing table: Destination NIC Gateway 0.0.0.0 WAN Cloud Network A LAN A RT A's WAN RT A's routing table: Destination NIC Gateway 0.0.0.0 WAN LAN A Network B WAN LAN A RT B's routing table: Destination NIC Gateway 0.0.0.0 WAN LAN B Network A WAN LAN B I would like to permit PC A and PC B to communicate, but I don't have access to RT C. Networks B and BC are new. Can PC A send a packet to RT B's WAN NIC (which is possible) and "ask RT B to direct the packet to PC B" ? I believe replacing RT B with a VPN server should do the trick, but I would like to know if it is possible to make it without establishing a new connection.

  • How do I create a wifi network bridge with qemu on OS X?

    - by a paid nerd
    I grabbed a small FreeBSD live CD and QEMU, and I'm trying to bridge my Mac OS X 10.8 wifi connection so that the guest OS is available on my LAN. However, the guest OS never gets a DHCP lease. This works perfectly with VirtualBox in their "bridged" network mode, so I know it can be done. I need to get it working with QEMU because VirtualBox doesn't support the architecture that I need for this project. Here's what I've done so far based on hours of googling: Installed TUNTAP for OS X Told OS X to supposedly forward all packets, even ARP: (NOTE: This doesn't appear to work.) $ sudo sysctl -w net.inet.ip.forwarding=1 $ sudo sysctl -w net.link.ether.inet.proxyall=1 $ sudo sysctl -w net.inet.ip.fw.enable=1 Created a bridge: $ sudo ifconfig bridge0 create $ sudo ifconfig bridge0 addm en0 addm tap0 $ sudo ifconfig bridge0 up $ ifconfig bridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500 ether ac:de:xx:xx:xx:xx Configuration: priority 0 hellotime 0 fwddelay 0 maxage 0 ipfilter disabled flags 0x2 member: en0 flags=3<LEARNING,DISCOVER> port 4 priority 0 path cost 0 member: tap0 flags=3<LEARNING,DISCOVER> port 8 priority 0 path cost 0 tap0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500 ether ca:3d:xx:xx:xx:xx open (pid 88244) Started tcpdump with -I in the hopes that it enables promiscuous mode on the wifi device: $ sudo tcpdump -In -i en0 Run QEMU using the bridged network instructions: $ qemu-system-x86_64 -cdrom mfsbsd-9.2-RELEASE-amd64.iso -m 1024 \ -boot d -net nic -net tap,ifname=tap0,script=no,downscript=no But the guest system never gets a DHCP lease: If I tcpdump -ni tap0, I see lots of traffic from the wireless network. But if I tcpdump -ni en0, I don't see any DHCP traffic from the QEMU guest OS. Any ideas? Update 1: I tried sudo defaults write "/Library/Preferences/SystemConfiguration/com.apple.Boot" "Kernel Flags" "net.inet.ip.scopedroute=0" and rebooting per this mailing list suggestion, but this didn't help. In fact, it made VirtualBox bridged mode stop working.

  • How have I locked me out from my Ubuntu VPS?

    - by Sanoj
    I have a Ubuntu Server as VPS (OpenVZ), and yesterday I installed php-fpm, but I guess something went wrong with the installation. Because since then I cannot log in to my server over SSH with PuTTY or using WinSCP. The message I get when connecting is Network error: Connection timed out. Immediately after the installation I was not able to use emacs either, I had to re-install it with apt-get install emacs. I have tried with clearing the firewall and rebooting the server from my web-based "control panel", but it doesn't help. The commands I used for installation of the PHP-fpm was from Installing PHP 5.3, Nginx And PHP-fpm On Ubuntu/Debian. And I guess it has something to do with these commands: cd /tmp wget http://us.archive.ubuntu.com/ubuntu/pool/main/k/krb5/libkrb53_1.6.dfsg.4~beta1-5ubuntu2_i386.deb wget http://us.archive.ubuntu.com/ubuntu/pool/main/i/icu/libicu38_3.8-6ubuntu0.2_i386.deb sudo dpkg -i *.deb sudo echo "deb http://php53.dotdeb.org stable all" >> /etc/apt/sources.list sudo apt-get update sudo apt-get install php5-cli php5-common php5-suhosin sudo apt-get install php5-fpm php5-cgi The web-sites that are hosted from my server works fine. Anyone that have the same experience or know how this could happen? I guess that I have to re-install Ubuntu Server from my "control panel" now, but I would like to avoid this situation in the future. Finally, I have backup on everything so nothing is lost if I have to re-install the machine.

  • Correct way to set up office network - 8 workstations, a file server and a staging server

    - by naunu
    Our office had this old school windows 2003 domain setup, our server caught fire, and now we are looking to do it right from scratch. Here is what we need: 5 PC and 3 Mac workstations for web development, they will each have WAMP/MAMP setup on them, managed by their developers. We will have a file server for assets, and a LAMP server with an external IP for staging. Here is what we have to work with: 5 IP addresses, brand new PC file server with windows 2008 SE, D-Link DSS-16+ 16 port switch, belkin 5 port wireless router, cable modem with 4 ports. How I have it set up now (this is a temporary makeshift setup): Cable modem = LAMP server, wireless router Wireless router = Switch = All of the workstations and file server (setup as a workgroup). We have noticed our internet is very slow with us all plugged in to the switch, and the switch plugged in to the router. I am not positive, but I think it is because our router does not have NAT. We are also having problems with the MACs connection to the network drive - it keeps disconnecting. I want this done right, and we have a ~$600 budget to buy anything else we need. Does anybody have any advice for me? Should I set up a domain or workgroup?

  • NX Client for Windows 7 Opens Remote Desktop in Multiple Windows

    - by Corey Kennedy
    What I'm trying to do: access my Ubuntu desktop remotely via NX Client on my Windows 7 laptop. My environment: server: Ubuntu 10.10 on AMD 1Ghz/512MB RAM PC client: Windows 7 on ThinkPad sl510 Software: server is running NXServer 3.4.0. Using xfce4 window manager. Laptop is using NXClient for Windows In my NX Client "Desktop" settings I've selected "Unix" and "Custom" for OS and environment. I've also specified "startxfce4" as the application to launch when NX connects. I am able to authenticate an NX session on my laptop. By this I mean, I can start the client on my laptop, enter credentials for my Linux user, and NX establishes a connection to the server and attempts to open a remote desktop window. The problem, though, is that this remote desktop is "fragmented" into many Windows. One window will display the bulk of my desktop (complete with desktop icons for "Home," "File System," and "Trash") while another window will contain the taskbar, and another window will contain the application strip. I can select each of these Windows individually, but I cannot click on any objects within them. I've searched Super User, Ubuntu Forums, NX help, Server Fault, and tried many Google searches - none have turned up another case of this particular problem. I'm stumped. Does anyone have any suggestions for what I might try? I'm guessing the problem has to do with my xfce config files, but I've only just setup this server - it's been a long time since I've used Linux and there's a lot I just don't know. What I am NOT trying to do: use Desktop sharing from Ubuntu, whereby I VNC into a desktop that I've already established on the server. I am trying to configure this Linux box as a headless server that I can stash someplace out-of-the-way in my house, then interact with through my laptop. I don't want to have a monitor or keyboard connected to the Linux box. Thanks for your help!

  • Need to boot into chkdsk from USB on Windows netbook

    - by Gaz Davidson
    While attempting to install Ubuntu on a 32-bit Windows XP netbook, the partition resize operation failed due to inconsistencies in the NTFS filesystem (lesson learned: run chkdsk /f in Windows before trying to resize a partition in Linux). Now the installer only gives the option to replace Windows with Ubuntu, the partition can't be resized in gparted, which displays a red exclamation mark and an error log when you click it. To make matters worse, we're also unable to reboot into Windows to get at chkdsk. We get a BSoD when choosing any of the options (including the DOS recovery console thing). The netbook has no CD-ROM drive, contains no recovery image and our only connection to the Internet is via the hotspot on my mobile device. We don't have Windows recovery CDs, but we do have a USB flash drive. We have a 64-bit laptop running Ubuntu 12.04 and Windows 7 (both 64-bit). So, on to the question: Is anyone aware of a way to get into a DOS recovery console and run chkdsk from a USB disk drive, without having to pirate Windows XP or download hundreds and hundreds of megabytes of crap? If it was my device I'd just flatten it, but it isn't. Please help!

  • Spammer relaying via Postfix mail server

    - by Paddington
    I have a Plesk 9.5 mail server (cm.snowbarre.co.za) on Ubuntu 8.04 LTS which forwards all SMTP traffic to an anti-spam server cacti.snowbarre.co.za.

  • subdomain .htaccess redirection via ssh remote port forwarding

    - by Achim
    I ask you to help me URL redirecting a subdomain to a SSH remote forwarded port: The current setup is the following: The server A have a local webserver running on port 80. This server is connected to a DSL line or a GPRS connection where the IP address changes often. To prevent a DynDNS setup we established a SSH remote port forwarding to a server B with a static IP adress. This is done on server A by the following statement: ssh -N -p 80 -g -R 10000:localhost:80 tunneling@<Server B IP> So by accessing the new port 10000 of the servers B IP-adress, all traffic is forwarded to the server A port 80 - this works fine! But to offer a more comfortable url to the user I want to hide the server B IP-adress and offer a subdomain. My domain provider allows to add subdomains and redirections to some other servers. In general, this works, I've tested this with different servers. But it don't work if the destination is the port forwarded port of server B. The initial redirection is done, the request is send to server A and the response are forwarded to server B and shown in the browser - fine. But then the URL within the browser is switched away from the subdomain to the IP:port of server B. So the user don't see the subdomain in the URL string of the browser anymore. I've tried this with my providers subdomain redirection, as well as .htaccess redirect, as well as META refresh, the problem always persist. Is there a parameter in the ssh reverse forwarding setup (I guess this is the place where the fix have to be) to keep the typed in subdomain URL and not show the IP. Thanks Achim

  • How to remap IPs visible from local machine to IPs visible from a machine I have SSH access to?

    - by gooli
    I'm so far out of my depth I don't even know what to google for. There's a server I can connect to via SSH. Via that server I can access other server on its subnet via SSH. What I want to do is be able to access the machines that server has access to directly. Say the server IP is 192.168.7.7 and is the only one in the 192.168.x.x range I have access to. I'd like to configure things in such a way that when I to access say 192.168.7.100 on my machine, the connection will go through an SSH tunnel I open to 192.168.7.7 and out to 192.168.7.100. I would like this to work for any port if at all possible. I know I can set an HTTP proxy and even a SOCKS proxy, but I'm wondering is there is a way to actually remap some of the IP my machine sees to IP only visible from the remote machine. What would this configuration be called? IS this NAT, VPN, IP2IP or something else? How can I set up this on a Windows client box that connects via SSH to a Linux box? Sounds to me like I need to set up some kind of filtering on the network driver or possibly a virtual NIC, but I'm not sure where to go next.

  • 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.

  • BackupPC - why does it use rsync --sender --server ... ?

    - by Jakobud
    I'm in the process of experimenting with BackupPC on a CentOS 5.5 server. I have everything pretty much setup with default values. I tried setting up a basic backup for a host's /www directory. The backup fails with the following errors: full backup started for directory /www Running: /usr/bin/ssh -q -x -l root target /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /www/ Xfer PIDs are now 30395 Read EOF: Connection reset by peer Tried again: got 0 bytes Done: 0 files, 0 bytes Got fatal error during xfer (Unable to read 4 bytes) Backup aborted (Unable to read 4 bytes) Not saving this as a partial backup since it has fewer files than the prior one (got 0 and 0 files versus 0) First of all, yes I have my ssh keys setup to allow me to ssh to the target server without requiring a password. In the process of troubleshooting, I tried the above ssh command directly from the command line, and it hangs. Looking at the end of the debug messages for SSH I get: debug1: Sending subsystem: /usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /www/ Request for subsystem '/usr/bin/rsync --server --sender --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive --ignore-times . /www/' failed on channel 0 Next I started looking at the rsync flags. I did not recognize --server and --sender. Looking at the rsync man pages, sure enough, I don't see anything about --server or --sender in there. What are those in there for? Looking at the BackupPC config I have this: RsyncClientPath = /usr/bin/rsync RsyncClientCmd = $sshPath -q -x -l root $host $rsyncPath $argList+ And for the arguments, I have the following listed: --numeric-ids --perms --owner --group -D --links --hard-links --times --block-size=2048 --recursive Notice there is no --server, --sender or --ignore-times. Why are these things getting added in? Is this part of the problem?
