  • set tap0 using virt-manager for bridged wireless

    - by DaveO
    After 3 days I finally have kvm guests working on the network via wireless (link below - thanks!): My network is 192.168.1.0/24 on the host: sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward" sudo tunctl -t tap0 sudo ip link set tap0 up sudo ip addr add 192.168.1.25/24 dev tap0 sudo route add -host 192.168.1.30 dev tap0 sudo parprouted wlan0 tap0 on the guest: auto eth0 iface eth0 inet static address 192.168.1.30 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.25 and start the guest: sudo kvm /path/to/guest.img -net nic,macaddr=DE:AD:BE:EF:90:26 -net tap,ifname=tap0,script=no This works great and I can ping the local network and the internet back and forth between the guest. But how do I add these settings to the guest's xml config so I can start the guest via virt-manager with the same nic settings? ref: http://www.linuxquestions.org/questions/debian-26/kvm-wireless-bridge-network-691953/

  • My server appears to have been hacked+ scanssh run by zabbix is it normal?

    - by Niro
    I'm running a few EC2/Scalr instances with zabbix monitoring. I received complaints about one of my servers port scanning other servers. the logs show it is accessing port 22 on consecutive IP addresses. I looked at the processes list and saw scanssh is running under the user Zabbix. My question is- Is scanssh part of zabbix? Is it suppesd to run? I have active autodiscovery on zabbix but it is looking at another IP addresses and definately not port 20. Is it possible that something in the config of zabbix agent is controlling it and not the settings on zabbix server? What can I do to find out if zabbix is somehow misbehaving or it is a hacker? Any advice is highly appreciated.

  • Remote Desktop over SSH SOCKS proxy to bypass firewall

    - by scrumpyjack
    Hi folks, I'm trying to connect to a Windows server from my Mac using RDC2.1 for Mac. The problem is the server I need to connect to is guarded by the evil dragon - IP-based access control on a completely separate network. I have an IP I can get in on, but it's at my office (i.e. a completely separate network). Because that network isn't set up for VPN, I've set up a SOCKS proxy through an SSH tunnel (which is all working fine). (SSH proxy) Me (on my Mac) ----------> Office Linux box ----> Windows server (home network) (office network) (other network) From my Linux server in my office (the SSH server) I can telnet to port 3389 on the Windows server, no problem. But from my Mac I can't get so much as a squeak out of it. Any ideas?

  • Server 2008/Windows 7/Samba Unspecified error 80004005

    - by ancillary
    I have a Samba share on a LAN with 2008 PDC/DNS. Smb authenticates with AD and I have several Win7 Machines that can connect fine. I recently added a couple of new computers to the LAN which were imaged the same way (same software, etc.; different hardware so different drivers) as the other machines and they have the same policies set. I can not get the new machines to connect to the samba share no matter what. I am always met with either Unspecified Error 0x80004005 or Network Path not found. I've turned off the firewall; set LANMAN auth to respond to NTLM only/send LM & NTLM responses/use NTLM session security if negotiated in Local Sec Policy SEcurity Options; tried both ip and hostname to connect. SMB log shows that authentication succeeds; but then connection is immediately killed by the client. tcpdump shows nothing remarkable except that when trying to connect from the client via hostname there is an unknown packet type error: ack 201 win 255 NBT Session Packet: Unknown packet type 0xABData: (41 bytes) Here's a couple of lines from that error: 11:18:37.964991 IP 001-client.domain.local.49372 > smb.domain.local.netbios-ssn: P 1670:2146(476) ack 201 win 255 NBT Session Packet: Unknown packet type 0xABData: (41 bytes) [000] AA 46 96 FA D5 99 33 75 0C C4 20 CE 26 42 F3 61 \252F\226\372\325\2313u \014\304 \316&B\363a [010] F0 8C FB 65 18 17 40 A5 DB 42 BB 94 37 53 92 EC \360\214\373e\030\027@\245 \333B\273\2247S\222\354 [020] 55 98 7F C4 AE 3D 6B 10 C4 U\230\177\304\256=k\020 \304 11:18:37.964998 IP smb.domain.local.netbios-ssn > 001-client.domain.local.49372: . ack 2146 win 100 Here's smb.conf just in case (though don't see how if other machines are working fine): [global] workgroup = MYDOMAIN realm = MYDOMAIN.LOCAL server string = domain|smb share interfaces = eth1 security = ADS password server = 192.168.1.3 log level = 2 log file = /var/log/samba/%m.log smb ports = 139 strict locking = no load printers = No local master = No domain master = No wins server = 192.168.1.3 wins support = Yes idmap uid = 500-10000000 idmap gid = 500-10000000 winbind separator = + winbind enum users = Yes winbind enum groups = Yes winbind use default domain = Yes [samba-share1] comment = SMB Share path = /home/share/smb/ valid users = @"MYDOMAIN+Domain Users" admin users = @"MYDOMAIN+Domain Admins" guest ok = no read only = No create mask = 0765 force directory mode = 0777 Any ideas what else I could try or look for?

  • SSH command from PHP script - nothing, yet work at cmd line

    - by waxical
    I'm working on an EC2 box and trying to SSH command another box. The command works in command-line, even php -a interactive. However it does not work when running as apache. Example cmd:- system('ssh -i /home/me/keys/key.pem user@ip-xx-xxx-xxx-xxx-end.ip "ls"'); I've tried adding apache to wheel group, and gshadow on both boxes. I've also just tried chowning the pem file to apache. Nothing. Yet the command response fine in the two other use cases outlines. What's going on here? Anyone know?

  • SSH tunneling and NAT

    - by thonixx
    I have a virtual machine with an internal IP address and a running mailserver with IMAP/POP3/SMTP. Everything works fine except: When I do an SSH tunnel to the guest server and want to connect to the mailserver with mail.*. then it does not work. There is a connection timeout. But If i connect to the internal IP 192.168..* then it works. So what can I do to enable the access from the domain name to the virtual machine with SSH tunneling?

  • keepalived questions (requirements, abilities, limitations)

    - by Poni
    1) What are keepalived's (physical/network) requirements? Does the two (or more) keepalived' nodes need to be connected to the same switch? (something related to broadcasting maybe). 2) Can keepalived nodes run on different networks, "internet" networks? 3) Is keepalived depend on the router? (as far as I understand, the virtual IP should point to the real router/switch that connects both nodes). 4) Is keepalived "service-independent"? - What is keepalived's involvement domain? IPs only? Or is it service/protocol oriented? - Does it deal ONLY with IP, or is it designed for HTTP for example? - In other words, can I use it for custom (network-based) app? 5) Have more than one failover server? If the answer for question #4 is "yes", i.e it depends on the service type, then is there any general alternative? Preferably easy to install/configure :)

  • VPN: What should my Gateway remote ID be?

    - by Lynn Owens
    I have a Netgear ProSafe UTM. I set the Gateway local ID to it's WAN IP. But I'm not sure what to put for it's Remote ID. I want to be able to connect to it from a laptop across the internet. I can chose between: Remote IP FQDN Client FQDN Cert DN Frankly I've tried them messing around with them all but I'm just shooting in the dark, and the help desk docs are worthless. Also, Googling around seems to end up with lots of pages not really related to what I want. A lot of pages on configuring Cisco or Windows home networking or privacy advocates.

  • ASP.NET MVC hosting recommendations

    - by chris
    I'm looking for recommendations for hosting an asp.net MVC application. Obviously, we need to be able to have access to configure IIS directly - I'd prefer not to have to go thru a control panel. The web server needs to have a dedicated IP, since some clients will be accessing it via IP. We need at least a SQLServer 2005 database, ideally on the same box. Load and usage will be pretty low, so a virtual machine will probably be fine. Does any one have any recommendations that meet the above constraints?

  • Vmware Workstation Development Server on Laptop

    - by Koobz
    I'm running an Ubuntu guest OS on my Windows 7 laptop. Currently, I have it set up for bridged networking. The guest is os is configured for a static ip of 192.168.1.115, which depending on the network I'm connected to, may not be available. When I want to view my development work I hit that up in my web browser. I'm really looking for the following scenario: 1) My guest OS ip address stays constant. 2) I can access my guest os even if I don't have an internet connection, or a lan/router. 3) I can share files with my guest/host. How does one accomplish this using VMware Workstation?

  • Prevent users from Router 2 seeing Router 1 computers

    - by Patrick Robert Shea O'Connor
    I've got 2 Netgear N300 (WNR2000v3) routers. Here's my setup: Modem Router 1 Private Users/Router 2 Public Wireless Users on "Guest" Network. I want to prevent users who are connected to Router 2's "Guest" network from accessing anything that is connected to Router 1. There is an option when setting up the "Guest" network called "Allow guest to access My Local Network" which I thought if unchecked would do this very thing; however, I can still access files and such of computers connected to Router 1. Router 1 assigns 192.0.0.x IP addresses, Router 2 assigns 10.0.0.x IP addresses, how can they even see each other? Do I need to change the subnet or something else?

  • Connect ADSL modem SMC7904WBRA-N to CISCO RV082

    - by Cy.
    I have a SMC7904WBRA-N ADSL modem/router that connects to the internet with a static IP given by the provider. I've received a RV082 to create a VPN connection which is having problems to connect to the remote VPN Server. After many tries we deduced that the SMC7904WBRA-N is being problematic with the NAT and I have been suggested to put the SMC router into the appropriate DSL bridging mode so the RV082 gets direct access to internet with the static IP. Can you give me any hints on how could this be done? Which mode is that?

  • Slow Starting DHCP Client Service - HP Thin Clients

    - by Ryan
    We have recently began adding XPe thin clients to our domain in preperation for a new citrix environment. One thing that has been picked up on in testing is that they appear slow to boot. The issue manifest's it's self as the classic "Applying Computer Settings..." screen we are all used to seeing. After digging into the issue it appears the DHCP Client service is taking some time to load on boot, this varies but I would estimate it can take around 1 minute in some cases. I've eliminated the classic issues, DHCP is responding correctly and in quick time. DNS is not the cause and GPO's are applying promptly. A simple workaround is to assign the client a static IP which work's great so the TCP/IP servies are obviously firing up quickly, just not DHCP Client. Does anyone have any idea's on how I may be able to improve the service start time? Keen to find a better solution before I get my arm twisted into setting up 250 thin clients with static addressing!

  • make sure i've configured dns correctly

    - by user22817
    Hi, On my server with Windows Server 2008, i've added a new zone with my new domain: biografica.ro. I've added a name server for it: ns.biografica.ro and the ip of the server. Also i added two A hosts for ns.biografica.ro and www.biografica.ro. I've also defined first that name server on the site where i bought the domain and pointed it to my ip. Now, i understood that i have to wait 24-48 hours for this new domain to be available online. Question: - is this a way to check on the server that i've succesfully configured it? For instance: nslookup biografica.ro or nslookup www.biografica.ro or ping www.biografica.ro do not work locally, on the server... Can you give me an advice? Thanks.

  • Server problem (duh)

    - by j-t-s
    Sorry the title couldn't be more specific. I installed Abyss Web Server. I'm running Windows XP Home Edition and I have Wireless Mobile Broadband internet. I used to be able to access (and other people on other networks) my site by entering my ip address in the browser, but after I formatted, and the installed abyss web server again, this does not work anymore. There are no errors. I CAN visit my own site by entering my ip address BUT anybody else can't do the same, it just says "connecting" in the browser's statusbar and it never changes. I have consulted the docs and have found no help. Google hasn't helped with this problem either. Can somebody please help? Thank you :)

  • rsyslog appears to act on old configuration

    - by Jeff Lee
    I'm using a template to dynamically generate rsyslog filenames. I've made some changes from my original format, but rsyslog still appears to be using both the new template and the old after restarting. My filename template went from this: $template RemoteDailyLog,"/var/log/remote/%hostname%/%$year%/%$month%/%$day%.log" To this: $template RemoteDailyLog,"/var/log/remote/%hostname%/%fromhost-ip%/%$year%/%$month%/%$day%.log" I stopped rsyslogd using service rsyslog stop, deleted all of my log files using rm -rf /var/log/remote/*, and then restarted rsyslogd with service rsyslog start. The problem is rsyslog seems to be building folder structures of the type "/var/log/remote/%hostname%/%$year%/%$month%/%$day%.log" (i.e., without the remote IP), which no longer appears anywhere in my configuration. Is it possible that old log or config data have been cached somewhere and are being preserved through the server restart? This is creeping me out a little.

  • How to set up memcached to use unix socket?

    - by alfish
    While I could use memcached on Debian to use the default 11211 port, but I've had great difficulty setting up unix socket, Form what I'v read, I know that I need to create a memcache.socket and add -s /path/to/memcache.socket -a 0766 To /etc/memcached.conf and comment out the default connection port and IP, i.e. -p 11211 -l 127.0.0.1 However, when I restart memcached I get internal server errors on Drupal site. I'm trying to implement unix sockets to avoid TCP/IP overhead and boost overal memcached performance, however not sure how much performance gain one can expect of this tweak. I appreciate your hints or possibly configs to to resolve this.

  • I want to start my portfolio site using ASP.Net and I'm a bit lost about hwo to actually put it on t

    - by Papuccino1
    I found this site: www.discountasp.net They seem cheap enough and have a track record. I decided to host my site with them. Here's where I'm confused. I host the application (my website) with them and they give me an IP address, right? Users can visit my site by typing in that IP address right? (Of course once I move the index file and create a defauly web folder, etc.) Next step is buying a domain name right? Like www.mysite.com, right? Is this the way it's done, or am I doing it wrong?

  • EMC/Legato/Networker Failed to recover files : Cross Platform Recovery not supported.

    - by marc.riera
    Software used to backup: EMC / Legato Networker legato server : windows legato clients: same hardware (2 years ago fedora something , now ubuntu ) Trying to recover from an old client, which is no longer available. So this is the thing. On 07/20/2008 we backed up a samba server(fedora something) to a tape , setting 1 year as browse policy and retention policy. Now this tape is recyclable. We took down the dns name. We deleted the legato client configuration. That legato client was reinstalled and is doing other stuff on ubuntu 10.04, with a different name but same ip. Now, 2 years and some month later #### Now we need to recover a folder from 2008 backup, on the fedora-samba-server. First thing, legato does not show the client name because the config was deleted. We create it again. We just set the old dns back on track, pointing the same ip, where the old server was, same MAC address ;). We created a new 'old client configuration' pointing to the new server. (different legato ip for client "I suppose" ) The ssid where the needed folder is on 2 tapes, 20 and 22. The index for that backup is on tape 21. We put this tapes on the jukebox (IBMT4000) -- not important for the issue -- All three tapes expired its browsable and recoverable time. So they are on recyclable. We get the clone id from the ssid with following command: mminfo -avot -q "ssid=<ssid>" -r cloneid We set the tapes to notrecyclable nsrmm -S <ssid>/<cloneid> -o notrecyclable We change the retention for the tapes for a future date nsrmm -S <ssid> -e 01/20/2011 We check the dates are correct : mminf -avV -q "ssid=<ssid>" -r ssbrowse(26),ssretent(26),savetime So far its OK. We close the terminal. Restart the server, just for being sure. Finally, we recover the index for that ssid where the folder should be. nsrck -L7 -t "07/20/2008" oldservername.domain.org There, we open the Networker User, select the server, select the old client as source, select the new client as destination. And this is what I get. imgur image of output -- http://i.imgur.com/1nOr8.png Should I understand that I need to install whatsoever operating system that was running on the old "linux server"/"networker client" to be able to restore 26Mb of files? thanks

  • Why can't I connect to remote Microsoft SQL Server through SSH tunnel?

    - by Alexander
    I have at home a D-Link DIR-615 C1 router with DD-WRT. I set up the SSH server on the router, and log on through an SSH2-RSA passphrase-protected key. That router is the gateway between the local network and the internet. One of the computers on that network has Microsoft SQL Server 2008 installed, with TCP/IP protocol enabled through port 1433. I've set up port forwarding on the router, so that remote connections are possible and are, in fact, working (some developers log on remotely without problems). I am part of another network, that has internet access through a proxy server, which only has ports 80 and 443 opened. I can't connect to that MSSQL server on that remote server because 1433 port is closed on this network. I connected (using Putty) through 443 port to my router's SSH server, and set up 2 tunnels. One is for RDP (3389), and it's working. The other is for 1433 port, to connect to the server. I can't connect through the SSH tunnel to the MS SQL Server, neither through telnet, or through GUI clients. Am I missing something? Additional details: on connect, I get this error from SQL Server Management Studio: TITLE: Connect to Server Cannot connect to localhost:14330. ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 3) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=3&LinkId=20476 BUTTONS: OK The tunnel is configured like this: L14330 192.168.0.103:1433 192.168.0.103 is the permanent address of the SQL Server on the LAN. I also successfully forwarded TCP traffic of 3389 port to that IP, so tunneling is working to that IP address. When connecting without tunnel, through Microsoft SQL Server Management Studio, using the same method the connection establishes. Too bad my proxy doesn't allow 1433 port traffic, I wouldn't have this headache.

  • Assisting a user using VNC

    - by wizlog
    I'm trying to help a friend with their computer remotely. He has a version of VNC, I'm not sure which one, so I downloaded and installed the VNC Viewer and Listening Viewer. I ask my friend for his IP address and port number, and he tells me that every time he's used it, the person giving him assistance (remotely controlling his computer) gave him some kind of number. I should note that my friend is not tech savy, and it may have been an IP address, but I'm not sure. What kind of number would the user be looking for? Does this indicate his version of VNC, Does that even matter? I am completly forign to VNC and don't know where to begin looking for an answer myself, and (for whatever reason) I can't ask my friend to figure out what version of VNC he is using.
