  • Is there a convenient way to manually copy the Log Shipping *.trn files from one SQL 2008 server to

    - by Rick
    We have a remote SQL 2008 server (ServerB) that needs to keep a warm (15 minute interval is OK) copy of production data (ServerA). ServerA is also SQL 2008. Log Shipping looks like it will do the job. We can only get to the destination ServerB with remote desktop. Is there a way to set this up when we can't get to both servers from one Management Studio? We want to be able to temporarily (until a VPN is setup between our network and the ServerB network) manually export a small .trn file, copy it via remote desktop to ServerB and then manually import those transactions from the .trn file. My supervisor says he saw a post saying this is possible. We were just trying to avoid doing a full database backup and copying that every time. Thanks in advance for any suggestions on this.

  • How to solve 'Connection refused' errors in SSH connection?

    - by frbry
    I have an Ubuntu Server 10.10 32-bit in my home. I'm making SSH connections to it from my PC via Putty. The problem is, sometimes I'm able to login seamlessly. However, sometimes it gives me an error like this: Network error: Connection refused. Then, I dont't change anything, try to login a few times more, wait a while and try again. Sometimes I can log in, sometimes I cannot. It seems pretty random to me. What can I do to solve this? Edit: And Sometimes, Putty gives Network error: Software caused connection abort error after displaying login as: text. Here is the ping -t output: Pinging 192.168.2.254 with 32 bytes of data: Reply from 192.168.2.254: bytes=32 time=6ms TTL=64 Reply from 192.168.2.254: bytes=32 time=65ms TTL=6 Reply from 192.168.2.254: bytes=32 time=88ms TTL=6 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=3ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64 Reply from 192.168.2.254: bytes=32 time=1ms TTL=64

  • How do I decrypt WPA2 encrypted packets using Wireshark?

    - by Rox
    I am trying to decrypt my WLAN data with Wireshark. I have already read and tried eveything on this page but without any success (well, I tried the example dump on that page and succeeded, but I fail with my own packets). I caught the four-way handshake from another client connecting to the network. My network info is as follows: SSID: test Passphrase: mypass The above info would give this preshared key: 58af7d7ce2e11faeab2278a5ef45de4944385f319b52a5b2d82389faedd3f9bf In Wireshark in the Preferences--IEEE 802.11 I have set this line as Key 1: wpa-psk:58af7d7ce2e11faeab2278a5ef45de4944385f319b52a5b2d82389faedd3f9bf I have tried the different options of "Ignore the protection bit" but none works. What could I have missed?

  • Two Routers - 1 Port Straight to First Router

    - by apples
    At my house we have two Wifi routers one's connected directly to the modem and the other is plugged in down stairs as a second network(Directly connected to the first router) Is there a way that I could make it so that I have the second router have its own network, but have one or two ports that would act as if they were directly connected to the first router? That way I can port forward to devices on the second router. Here are the information about the routers: Router 1 - Linksys WRT54G Running stock firmware Router 2 - Linksys E900 Running Tomato Firmware So to summarize what I'm asking is how would I have two networks from two routers but be able to connect directly to the first router through one of the ports on the second router. Here's a Visio Drawing of what I would like to look like

  • CARP: two machines think they're the master, but only on one interface

    - by Conor McDermottroe
    I have two machines, each configured identically as a firewall/load balancer for a busy website. I have set them up with CARP and pfsync on both the internal and external interfaces. The internal interface is behaving as expected (primary listed as MASTER and secondary listed as BACKUP) On both machines, the network interfaces are as follows: em0 - External interface bge0 - Internal interface bge1 - Crossover connection between both machines carp0 - Shared external interface for CARP carp1 - Shared internal interface for CARP I've rewritten the IP addresses and MAC addresses below. The networks are as follows: 10.0.1.0/24 - External network 10.0.2.0/24 - Internal network 10.0.3.0/24 - Crossover network Here's the output from ifconfig on the primary: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4> ether [SNIP] inet 10.0.1.10 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet 100baseTX <full-duplex> status: active bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.2.10 netmask 0xffffff00 broadcast 10.0.2.255 media: Ethernet 1000baseT <full-duplex> status: active bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.3.10 netmask 0xffffff00 broadcast 10.0.3.255 media: Ethernet 1000baseT <full-duplex> status: active lo0: flags=80c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33152 pfsync0: flags=0<> metric 0 mtu 1460 pfsync: syncdev: bge1 syncpeer: 10.0.3.11 maxupd: 128 carp0: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.1.5 netmask 0xffffff00 carp: MASTER vhid 1 advbase 1 advskew 0 carp1: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.2.5 netmask 0xffffff00 carp: MASTER vhid 2 advbase 1 advskew 0 And here's the /etc/rc.conf excerpt from the primary: defaultrouter="10.0.1.1" network_interfaces="em0 bge0 bge1 lo0 pfsync0" cloned_interfaces="carp0 carp1" ifconfig_em0="inet 10.0.1.10 netmask 255.255.255.0 media 100BaseTX mediaopt full-duplex" ifconfig_bge0="inet 10.0.2.10 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_bge1="inet 10.0.3.10 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_carp0="vhid 1 pass [SNIP] 10.0.1.5/24" ifconfig_carp1="vhid 2 pass [SNIP] 10.0.2.5/24" pfsync_enable="YES" pfsync_syncdev="bge1" pfsync_syncpeer="10.0.3.11" And here's the output on the secondary: em0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=19b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4> ether [SNIP] inet 10.0.1.11 netmask 0xffffff00 broadcast 10.0.1.255 media: Ethernet 100baseTX <full-duplex> status: active bge0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.2.11 netmask 0xffffff00 broadcast 10.0.2.255 media: Ethernet 1000baseT <full-duplex> status: active bge1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=9b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM> ether [SNIP] inet 10.0.3.11 netmask 0xffffff00 broadcast 10.0.3.255 media: Ethernet 1000baseT <full-duplex> status: active lo0: flags=80c9<UP,LOOPBACK,RUNNING,NOARP,MULTICAST> metric 0 mtu 16384 options=3<RXCSUM,TXCSUM> inet6 fe80::1%lo0 prefixlen 64 scopeid 0x4 inet6 ::1 prefixlen 128 inet 127.0.0.1 netmask 0xff000000 pflog0: flags=141<UP,RUNNING,PROMISC> metric 0 mtu 33152 pfsync0: flags=0<> metric 0 mtu 1460 pfsync: syncdev: bge1 syncpeer: 10.0.3.10 maxupd: 128 carp0: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.1.5 netmask 0xffffff00 carp: MASTER vhid 1 advbase 1 advskew 20 carp1: flags=49<UP,LOOPBACK,RUNNING> metric 0 mtu 1500 inet 10.0.2.5 netmask 0xffffff00 carp: BACKUP vhid 2 advbase 1 advskew 20 And here's the /etc/rc.conf excerpt from the secondary: defaultrouter="10.0.1.1" network_interfaces="em0 bge0 bge1 lo0 pfsync0" cloned_interfaces="carp0 carp1" ifconfig_em0="inet 10.0.1.11 netmask 255.255.255.0 media 100BaseTX mediaopt full-duplex" ifconfig_bge0="inet 10.0.2.11 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_bge1="inet 10.0.3.11 netmask 255.255.255.0 media 1000BaseTX mediaopt full-duplex" ifconfig_carp0="vhid 1 pass [SNIP] advskew 20 10.0.1.5/24" ifconfig_carp1="vhid 2 pass [SNIP] advskew 20 10.0.2.5/24" pfsync_enable="YES" pfsync_syncdev="bge1" pfsync_syncpeer="10.0.3.10" What I don't understand is, the carp status on carp0 is MASTER on both machines when the status on carp1 is as it should be (MASTER on the primary and BACKUP on the secondary).

  • Can admins monitor my activity locally even when I use a VPN?

    - by Arjun Create
    My school has one of those super overreacting web blockers (specifically Fortisnet) that blocks things that should be accessible by a high-school senior trying to research projects. Despite many students' complaints the administration's hands are tied due to parents' complaints. I have setup a VPN account from http://www.vpnreactor.com. With this I am able to bypass the blocker. I know this service hides my IP from websites and servers on the web. I also know that the school pays an IT guy just to monitor sites and network traffic that the students are using. Basically, will he be able to see my network traffic? More importantly, will he be able to trace it to my computer or its MAC address? I am connecting over Wi-Fi, not ethernet.

  • Windows Server 2008 R2 DNS Server not working?

    - by wolfvilleian
    Hi, I have a server running Windows Server 2008 R2 hosting a DNS server, exchange 2010 and is a domain controller. One computer on the network (and domain) can ping the server 25% of the time, also when I try to ping it's own hostname it also does not work. However another computer that is on the domain can ping it fine, and another computer on the network but not domain can ping fine as well. The computer that cannot ping the server is setup to use the DNS server running on the server only (secondary dns points to nothing) and it will resolve the hostname of the server to the external IP not internal when the other two computers correctly resolve the internal All 3 computers and server are connected directly into the same switch. Does anyone have any ideas on how to fix this? Thanks

  • Can Linux works as 802.1X authenticator in bridge mode ?

    - by Kartoch
    I want to create a lab for my students with netkit (a network emulator based on 802.1X) to study 802.1X. I can create the authentication server (FreeRadius) and configure the client with XSupplicant connected by a switch (a Linux in bridge mode). I'm looking to a way to configure the switch as Authenticator, i.e.: when the client is connected, the switch only forwards EAP packets to the authentication server. then the switch lets the user access to the local network when the authentication server authorizes the client. At the present time there is a lot of documentation to do this with a wireless point but no one for a switch. Does anyone have an idea or know the good software for it ?

  • Looking for a Software to harden Windows machines

    - by MosheH
    I'm a network administrator of a small/medium network. I'm looking for a software (Free or Not) which can harden Windows Computers (XP And Win7) for the propose of hardening standalone desktop computers (not in domain network). Note: The computers are completely isolated (standalone), so i can't use active directory group policy. moreover, there are too many restriction that i need to apply, so it is not particle to set it up manual (one by one). Basically what I’m looking for is a software that can restrict and disable access for specific user accounts on the system. For Example: User john can only open one application and nothing else -- He don’t see no icon on the desktop or start menu, except for one or two applications which i want to allow. He can't Right click on the desktop, the task-bar icons are not shown, there is no folder options, etc... User marry can open a specific application and copy data to one folder on D drive. User Dan, have access to all drives but cannot install software, and so on... So far ,I've found only the following solutions, but they all seems to miss one or more feature: Desktop restriction Software 1. Faronics WINSelect The application seems to answer most of our needs except one feature which is very important to us but seems to be missing from WINSelect, which is "restriction per profile". WINSelect only allow to set up restrictions which are applied system-wide. If I have multiple user accounts on the system and want to apply different restrictions for each user, I cant. Deskman (No Restriction per user)- Same thing, no restriction per profile. Desktop Security Rx - not relevant, No Win7 Support. The only software that I've found which is offering a restriction per profile is " 1st Security Agent ". but its GUI is very complicated and not very intuitive. It's worth to mention that I'm not looking for "Internet Kiosk software" although they share some features with the one I need. All I need is a software (like http://www.faronics.com/standard/winselect/) that is offering a way to restrict Windows user interface. So IF anybody know an Hardening software which allows to set-up user restrictions on Windows systems, It will be a big, big, big help for me! Thanks to you all

    A computer, with Windows 7, can't access any website by domain suddenly. Whether this computer use a wired link or connect to the WLAN, The fault persists IP and DNS obtained automatically, and seems normal (ipconfig /all return the correct info) I can visit websites by using HTTP proxy The DNS server is available, other computer in my room works properly. I can ping myself, the gateway and any other IP, but domains I can use nslookup and obtain the correct IP info There are some error information in the event log about dns client events explaining the client can not verify the DNS server available Windows network diagnosis explain that Windows can't communicate with the device or resource (Primary DNS Server) I guess the dns client should be blame. I tried to do the following things but the fault persist. Reinstall the driver of network adapter Reset TCP/IP (netsh int ip reset) Reset Winsock (netsh winsock reset) Reset LSP I don't want to reinstall the whole os, what should I do?

  • WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256

    - by user702295
    WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256 I am running my engine on Linux and am receiving an intermittent message "WARNING Retrying bulk insert for file: sqlldr due to communication Error: 256" The engine seems to have completed successfully, but it is not clear if this error caused some of the forecast to not complete. It is also not clear what caused the error. Generally if you see only the WARNING of it, it means that next retries of the same load request have eventually succeeded and so the run a a whole is not affected. In order to know more about what happens, look for .log/.bad files left in the engines bin directory or possibly a quote of them within the specific engine log that had the issue.  The sqlnet.log file may also have some information about it and perhaps at the database server side there may be some log/alert regarding what happened.  Look at the alert.log. In general it could be that the database server/network was over loaded at the time and somehow the connection was rejected/failed/aborted either due to specific setting on concurrent connections/sessions or inadvertently due to glitch in network/os/hardware. If this repeats and becomes more frequent during the run you should look further into it as mentioned above. You can also track this using either SQL*Trace or java.util.logging.  - Globally enable logging by setting the oracle.jdbc.Trace system property java -Doracle.jdbc.Trace=true - Client Side Tracing: Your SQLNET.ORA file should contain the following lines to produce a client side trace file: trace_level_client = 10 trace_unique_client = on trace_file_client = sqlnet.trc trace_directory_client = <path_to_trace_dir> Server Side Tracing: To enable server side tracing, use the following parameters: trace_level_server = 10 trace_file_server = server.trc trace_directory_server = <path_to_trace_dir> Tracing Levels: The following values can be used for TRACE_LEVEL* parameters:     16 or SUPPORT — WorldWide Customer Support trace information     10 or ADMIN — Administration trace information     4 or USER — User trace information     0 or OFF — no tracing, the default Additional information is readily available via the web.

    Hi, I have bunch of questions: I have a Mac network, which has five Mac's. Right now, they are individually getting software updates. Is there a way to download the patches/security updates in a single place (repository) and point all machines to this location? Personally, I have tools like Monolingual and Onyx, but are there tools you could recommend that affect the performance of the Operating System positively? Tweaks would be nice. Links and pointers, would be really appreciated. I've read about Time machine, is there a way to backup all machines to a network drive using this tool? Thanks!

  • How can I force Parallels' networking to obtain an IP through a wireless router?

    - by RLH
    Here is my setup. I have a Macbook, Thunderbolt display and an Ethernet connection plugged into the Thunderbolt display. During the day, most of my network use can (and should) operate across the ethernet associated with my display. However, I also need to be able to connect up to a wireless router. This hasn't been a problem on the Mac OS X side, but the program that I need to run on the router has to obtain an IP address from the wireless access point. Considering my current setup, how can I leave it so that I can access the internet in OS X, yet have my Window 7 instance running in Parallels, get it's assigned IP address from a wireless router that my Mac is also connected to? I've fiddled around with the Parallel's network settings for an hour, and I can't get Parallel's to see the router, even though my Mac is certainly connected to it.

  • What equipment do real ISP's use?

    - by Allanrbo
    In a dormitory of 550 residents, people often mistakenly set up DHCP servers for the whole network by plugging in their private Wi-Fi routers wrongly. Also recently, someone mistakenly configured their PC to a static IP being the same as that of the default gateway. We use cheap 3Com switches at the moment. I know that Cisco switches support DHCP snooping to solve the DHCP problem, but that still does not solve the default gateway IP takeover problem. What sort of switch equipment do real ISP's use so their customers cannot break the network for the other customers?

  • Aperture and networked drive: thinks images are offline

    - by AK
    I keep my photos on a networked drive (wireless), and they are referenced by Aperture. Aperture seems to not try very hard to look for this drive. Usually I have to open the network drive in Finder before opening Aperture -- otherwise it doesn't find the images and considers them offline. To me this seems like Aperture isn't willing to look on the network for the drive, unless it was helped along by pointing it out in Finder. It doesn't work if I start Aperture first and then navigate to the drive in Finder. What are some workarounds to making this functional? Is there a way to tell Aperture to look again without restarting the program?

  • SMB super slow within LAN between MAC and PC

    - by asdcasdc
    I have a windows desktop which stores all my movies, songs and pictures. I have a mac laptop which I would like to access these files. I don't want to utilize the FTP or SCP protocol because I don't want them to be downloaded to my mac. I want to access them as if they are a network mounted disk. So I tried using the native SMB protocol (available in Finder - Go - Connect to server). I tried dragging a file and dropping it onto my MAC's desktop. Surprisingly, I am only able to transfer at a very slow rate of about 1mb/s. Assuming network connectivity is not a problem, has anyone experienced incredible slowness with SMB? Are there alternative protocols for me to use in this case between PC and MAC?

  • Bridging VirtualBox over OpenVPN TAP adapter on Windows

    - by Sean Edwards
    I'm trying to configure a virtual machine (VirtualBox guest running Backtrack 4) with a bridged adapter over a VPN connection. The VPN is is hosted by the cybersecurity club at my university, and connects to a sandboxed LAN designed for penetration testing against various servers that the club has built. My host (Windows 7 Ultimate) connects to the VPN fine and is assigned an IP through DHCP, but for some reason the VM can't do the same thing, and I'm not sure why. It's like OpenVPN is filtering out packets from the MAC address it doesn't recognize. I want the virtual machine to bridge over the VPN connection, because our IT office has very strict policies about what you can and can't do on the network. I want to be able to run active attacks (ARP spoofing, nmap, Nessus scans) in the sandbox environment without risking the traffic accidentally going over the university network and getting my internet access revoked. Bridging over the VPN connection and running all attacks from inside the VM would solve that problem. Any idea why the host can use this interface, but the VM can't?

    I understand that Tunnel Adapter LAN is for encapsulating IPv6 packets with an IPv4 header so that they can be sent across an IPv4 network. Few queries popped up in my mind based on this :- If i do 'ipconfig', Apart from ethernet adapter LAN details, I get a series of statments as below - Tunnel adapter Local Area Connection* 6 Tunnel adapter Local Area Connection* 7 Tunnel adapter Local Area Connection* 12 Tunnel adapter Local Area Connection* 13 Tunnel adapter Local Area Connection* 14 Tunnel adapter Local Area Connection* 15 Tunnel adapter Local Area Connection* 16 Except for the *16, all the other Tunnel Adapter Local Area Connections show Media Disconnected. Why is the numbering for the Tunnel adapter LAN not sequential? It is like 6, 7, 12, 13, 14, 15, 16. A strange numbering scheme! I tried to figure it out by thinking of some arithmetic series. But, it does not seem to fit in. There is a huge gap between 7 and 12. Any ideas? What is the need for so many Tunnel Adapter LAN connections? Can you tell me a scenario that requires all of those ? I did ipconfig /all to get more information. From the listing, I understand that: 16, 15, 14, 12 are Microsoft 6to4 Adapters 13, 6 are isatap Adapters 7 is Teredo Tunneling Pseudo-interface I understand that the above are for automatic tunneling so that the tunnel endpoints are determined automatically by the routing infrastructure. 6to4 is recommended by RFC3056 for automatic tunneling that uses protocol 41 for encapsulation. It is typically used when an end-user wants to connect to the IPv6 Internet using their existing IPv4 connection. Teredo is an automatic tunneling technique that uses UDP encapsulation across multiple NATs. That is, It is to grant IPv6 connectivity to nodes that are located behind IPv6-unaware NAT devices ISATAP treats the IPv4 network as a virtual IPv6 local link, with mappings from each IPv4 address to a link-local IPv6 address. That is to transmit IPv6 packets between dual-stack nodes on top of an IPv4 network. That is, to put in simple words, ISATAP is an intra-site mechanism, while the 6to4 and Teredo are for inter-site tunnelling mechanisms. It seems that Teredo should alone enabled by default in Vista, But my system does not show it to be enabled by default. Interestingly, it shows a 6to4 tunnel adapter (Tunnel adapter LAN connection 16) to be enabled by default? Any specific reasons for it? If i do ipconfig /all, why is only one Teredo present while four 6to4 are present ? I searched the internet for answers to the above queries, but I am unable to find clear answers.

  • windows 7 losing wired ethernet connection

    i have a win 7 machine with an Atheros L1 Gigabit Ethernet 10/100/1000Base-T Controller with latest drivers, the machine is upto date with all latest fixes etc. I have it connecting to a WRT310Nv2 router. Seemingly random, win 7 disconnects from the "Home Network" says its in a "public network", then resets the connection to an illegal 169 address. I have tried static ips, dhcp, all with the same results. This seems to have started shortly after i installed Vuze, so I uninstalled it but the problem persists. I know that the router is sound given that I have an XP machine attached with no issues of connectivity at all. I am at a complete loss and have tried everything, pleasse tell me i'm not the only one.
