  • When I log on to my company desktop, I log on to a domain. How is this domain name installed?

    - by learnerforever
    Hi, When I have to work on my machine in company, I have noticed that I log on to a domain (named on the basis of company name) and not really on that computer. From, what I understand, this has a few advantages, the primary being that I just need one password for the domain and can work through any of the machines in company. My questions are : What software on desktop/network have to be installed so that the desktop recognizes and gives me option of logging into a domain. I would guess that a software can be installed on desktop, and there we can configure the IP address of domain server of company and port number, which handles authentication. Is this correct? This takes me to another question that how are softwares installed on end machines in a company. Going to each machine physically and installing looks very unweildy from administrator point of view. An obvious solution would be to install softwares (and updates) over network. My question on this are: What protocols,keywords come into picture when administrator installs OS,softwares,updates from his administrator machine to end machine through network. Thanks,

  • Can reprepro accept a new version of a package into the repository?

    - by kai
    I have installed a package into my own debian package repository like so: $ sudo reprepro -b /var/packages/ubuntu includedeb maverick my-package_0.8-0_all.deb my-package_0.8-0_all.deb: component guessed as 'main' Exporting indices... I have installed my package on a few machines using apt-get install. I have now added new features to my software and would like to add a new minor version of my package to the repository so that I may update my machines using apt-get upgrade. I try to do this like so: $ sudo reprepro -b /var/packages/ubuntu includedeb maverick my-package_0.9-0_all.deb my-package_0.9-0_all.deb: component guessed as 'main' Skipping inclusion of 'my-package' '1.0-0' in 'maverick|main|i386', as it has already '1.0-0'. Skipping inclusion of 'my-package' '1.0-0' in 'maverick|main|amd64', as it has already '1.0-0'. It looks like I need to tell reprepro that this is a new version of the same package but I have no idea how to do this. I have read the reprepro man page several times and searched on the net for a couple of hours but I have not found any answers. Am I missing something? Many thanks.

  • To clone or to automate a system installation?

    - by Shtééf
    Let's say you're setting up a cluster of servers performing the same task. Or say you're just setting up a bunch of different servers, but you expect to use a base configuration on all of your servers. Would it be better practice to create a base image and clone it, or to automate the installation and configuration? I occasionally end up in this argument with my boss, in situations where we're time-pressed. When he sees me struggle with perfecting the automation, his suggestion is often to clone the entire disk to the other machines. But my instinct has always been to avoid cloning. This is mostly from an Ubuntu perspective, but the question is fairly general. My reasons for avoiding cloning are: On a typical install, even if it's fresh, there are already several unique identifiers installed: filesystem UUIDs, SSH host keys, among others. These would have to be regenerated. Network needs to be reconfigured for each clone. This would need to be done off-line, of course, or the settings will conflict with other machines on the network. On the other hand, some of the cloning advantages are quite clear as well: (Initially?) less effort required than automating configuration. Tools exist to quickly address (some) of the above disadvantages. (I can see right through my own bias there.)

  • Cassandra Remote Connection

    I'm not managing to connect to cassandra from outside machines. The database is hosted on a windows machine and im trying to connect through a mac (but this shouldn't cause problems) Local connection works: C:\cassandra\bin>cassandra-cli Starting Cassandra Client Connected to: "Test Cluster" on 127.0.0.1/9160 Welcome to Cassandra CLI version 1.1.6 But fails from other machines on the same network bin/cassandra-cli --host 192.168.0.10 --port 9160 org.apache.thrift.transport.TTransportException: java.net.ConnectException: Operation timed out at org.apache.thrift.transport.TSocket.open(TSocket.java:183) at org.apache.thrift.transport.TFramedTransport.open(TFramedTransport.java:81) at org.apache.cassandra.cli.CliMain.connect(CliMain.java:70) at org.apache.cassandra.cli.CliMain.main(CliMain.java:246) Exception connecting to 192.168.0.10/9160.

  • MAC addresses on dual-NIC mainboards

    - by Tom O'Connor
    Here's a weird problem. We've got a number of devices with dual-NIC mainboards. Some are Realtek NICs, which suck. Some are Intel e1000s, which don't. I've just noticed on 2 machines, one is an Intel NIC, one is a Realtek, that when I put the MAC address of one machine into the dhcpd.conf file on our DHCP server to get it to PXE boot the machine into a rebuild environment, initially everything is fine. The server gets a DHCP allocation, and PXE boots into the Ubuntu preseed enviroment. On one or two machines, it gets as far as Ubuntu's DHCP network configuration, and fails. If i pull up a busybox shell (on tty2 on the installing machine), and run ip link, I can see that the UP flag is set on the other NIC. Here's some stuff. host xeon16-ghz240-gb48-node1 { hardware ethernet BC:AE:C5:07:1F:18; filename "pxelinux.0"; next-server 192.168.123.80; } That's what's in dhcpd.conf This is what ip link on the evil machine looks like. Only one NIC is actually connected (deliberately). As you can see, the NIC that's in the dhcpd config, is not marked as UP, and the link that is UP, isn't the one in DHCP. So far I've seen this on two brands of dual-NIC configuration. Does anyone know 1) what's causing it, and b) What we can do about it?

  • Server Performance

    - by sb12
    I know very little about performance tuning of servers etc... so i thought i'd put this up here as i start some research on it, just to get some direction. I am in the process of migrating from my old server to a new one - both are 64 bit machines. One is a few years old, the other brand new (PowerEdge R410). The old server spec is: 2 cpus, 3.4GHz Pentiums, 8G of RAM, Fedora 11 currently installed The new server spec is: 16 cpus, 3.2 GHz Xeon, 16G of RAM, CentOS 6.2 installed. Also RAID10 is on the new server - no RAID on the old one. Both servers currently have the same database (MySQL) with the same data migrated. I wrote a Perl script that simply steps through each row of a table in the database (about 18000 rows) and updates a value in that row. Every row in the table is updated. Out of curiosity i ran this perl script on both machines, just to see how the new server would perform vs. the old one, and it produced interesting results: The old server was twice as fast as the new one to complete. Looking at the database, both are configured exactly the same (the new one being a dump of the old one...)... Anyone any ideas why this would be given the hardware gap between both? As i said i'm about to start some digging, but thought i'd put this up here to maybe get some good direction.... Many thanks in advance..

  • bind9 "error sending response: host unreachable"

    - by wolfgangsz
    of course), I have a number of DNS servers, all running bind9 (9.5.1, to be specific) under fedora. 4 of them are slaves, fed by a common master for our public DNS. These are all located on the public gateways of our various offices. One of them has tons of messages in its log files similar to these: Jul 21 17:26:18 gateway named[3487]: client 10.171.3.8#52500: view internal: error sending response: host unreachable I wonder where that comes from. The firewall is open on port 53 between the two machines (10.171.3.8 is an internal DNS server located on a Windows Domain Controller). The internal domains do NOT list the gateway as a name server (so there should not be any attempts of replicating the domains), and the gateway does not handle any internal DNS. The clients in these messages vary between the two domain controllers on the internal network and a third internal name server (running bind9 on debian in a different segment of the network). Any pointers are highly welcome. In response to the first reply: The issue with this really is that tcpdump doesn't show any problems. Here is an extract from "tcpdump -i any port 53" 09:13:38.283308 IP valine.aminocom.com.61815 ns-pri.ripe.net.domain: 14075 PTR? 166.225.58.95.in-addr.arpa. (44) 09:13:42.007410 IP gateway-eng.aminocom.com.37047 alanine.aminocom.com.domain: 35410+ PTR? 12.3.172.10.in-addr.arpa. (42) At the same time, the DNS log shows: Jul 22 09:13:38 gateway named[3487]: client 10.171.3.6#61300: view internal: error sending response: host unreachable Jul 22 09:13:40 gateway named[3487]: client 10.172.3.12#56230: view internal: error sending response: host unreachable Jul 22 09:13:40 gateway named[3487]: client 10.171.3.8#55221: view internal: error sending response: host unreachable Jul 22 09:13:49 gateway named[3487]: client 10.171.3.8#51342: view internal: error sending response: host unreachable So clearly at 09:13:40 there were two unsuccessful attempts to connect to internal machines (10.172.3.12 and 10.171.3.8, both are DNS servers), but nothing in the tcpdump output.

  • How to use connectify to share files between 2 laptops, one running Windows 7?

    - by p2pnode
    I have 2 laptops one running XP and another Windows 7. Both have WiFi-card installed. I want to be able to share files between these 2 machines and then in next step also be able to share internet connection. I have heard that Connectify on Windows 7 is a very handy and easy tool to set up a hotspot and other machines even XP,Vista can connect to this host hotspot and share files and internet connection. I am able to search for the network (set on host) on my client machine. But how to share files? I don't see any such menu or anything. Also after I have installed connectify on Windows 7, I am not able to connect to internet using data card. It throws error that "Error 31:A A device attached to the system is not functioning". And on client machine, if I connect to data card, as well as connect to wireless network setup by host machine, I no longer am able to access internet, even though the data card is connected. The browser throws error: Please help. Any other utility similar to connectify etc?

  • In Windows 7, why can't I use perfmon against a remote server?

    - by SomeGuy
    I am on Windows 7 and trying to run perfmon against Windows 2003 and Windows 2008 servers. I am running into the same issue with all remote machines. When creating a data collector set, I specify a domain account that is in the administrators group on the remote machines (and "Performance Log Users" and "Performance Monitor Users" to be safe). On the "Available Counters" screen, When I type in a remote computer name, PerfMon locks up for a good 2-3 minutes before I can add any counters. I can then save the collector set. However, when I save it, the go/stop buttons are disabled if I click the set in the left panel, and missing if I click the Data collector set itself in the right panel. See the screens below. I can run data collector sets against my local machine with no problem. I am opening perfmon with my local account in both scenarios. I also have Remote Registry Service started on each remote machine. What is going on?

  • Multiple public IPs through DD-WRT without 1-to-1 NAT

    - by Stephen Touset
    I've done a search here and wasn't able to find anything relevant to my situation. I apologize in advance if I've missed an existing post on the topic. Our ISP has provided us with 6 static IP addresses. We are currently using two of them (plus one for the Comcast-provided router). One of the static addresses routes to our internal network, and the other goes to our VOIP phone system. Unfortunately, the Comcast machine doesn't support QoS, so our VOIP calls have been choppy. We plan to put the Comcast-provided router into bridge mode and replace it with an ASUS RT-N16 running DD-WRT. However, I'm unsure how to set up DD-WRT to function similarly to our existing Comcast router. The Comcast router's WAN IP is the first of our static IP addresses. We did not need to provide an internal LAN IP address — simply connecting machines that use our other public addresses to the LAN ports on the Comcast router is enough for it to route between the connected machines and our internet connection. Is there a way to do a similar setup through the DD-WRT? Thanks in advance.

  • Enabling Hyper-V Integrated Services Time Sync Services versus Internet Time Synchronization

    - by cpuguru
    Should I deselect the "Synchronize with an Internet Time Server" checkbox under the VM's "Date and Time - Internet Time Settings" tab if the "Time Synchronization Service" for a Hyper-V-based Virtual Machine is enabled? One of the Integration Services that Hyper-V provides is the Time Synchronization Service, which can be enabled/disabled by going to a VM's Settings-Integration Services setting in the Management section. I believe this is checked by default. When you install a Windows Server 2008 OS in a VM on the Hyper-V server, it comes with the "Synchronize with an Internet Time Server" option set, pointing to "time.windows.com". I'd think that if the parent Hyper-V server is set to one time server, and the child VM is pointing to a different time server, there would be a momentary blip if the two are not spot on with their times when the synchronization services run. So the question is, which time sync service should I use? I'm assuming not both. And what is the advantage of one over the other? Note: This question assumes that the machines are not joined to a domain. If they were, the machines would also try to update their time against the domain controller with the primary domain controller role too, right? Thanks!

  • Persistent static route stops working after VPN drops and reconnects

    - by user76157
    I've got a VPN between two networks, one home and one office (A and B). Their subnets are: (A) 192.168.1.0 and (B) 192.168.0.0 The two networks have identical ADSL routers. Unfortunately these can only do dial-out VPN. So I've got a Windows 2008 server on Network B acting as a VPN server (ServerB). Network A's router (RouterA) passes through Network B's router and connects via PPTP to ServerB. RouterA is assigned the static IP 192.168.0.40 on Network B. There's a persistent static route on ServerB telling it to use 0.40 for all requests to Network A's subnet, 192.168.1.0. (route -p add 192.168.1.0 mask 255.255.255.0 192.168.0.40). This enables ServerB to ping all machines on A (and those machines to ping ServerB). The VPN connection occasionally drops (I'm not sure why - it's set to remain always on and seems to drop randomly). This wouldn't be too much of a problem, as it reconnects automatically and quickly, except that when it does reconnect, the static route on ServerB no longer works. Route print (on ServerB) shows that the persistent static route still exists. However a tracert to a machine on Network A doesn't use the static route; it tries instead to use ServerB's default gateway (which is RouterB), and fails to find the machine. Deleting and re-adding the static route fixes the problem - a tracert uses the static route. At the moment, a batch file to delete and re-add the static route is scheduled to run every day. But this is clearly far from an ideal solution! I hope that's not too confusing. Any help would be very much appreciated.

  • Adding Static IP's to the NIC

    - by Brett Powell
    We are currently working on migrating a lot of new machines to our network, and my job this morning was to setup all of the IP Addresses. I worked on this all morning, and when I got back tonight I was informed that they had all been setup incorrectly, and had to be removed and re-added. I am quite confused as I have been setting up IP's on machines for a long time and I am curious as to what the issue is. Just taking into account this example... 72.26.196.160/29 255.255.255.248 A /29 block is 5 usable IP's. With the script I wrote and used, the IP Addresses .162 - .166 were added to the NIC. I can't remember now what the name for .161 was, but isn't it the broadcast address or something which isn't assigned to the NIC when adding additional IP Blocks? I am curious as to where my logic is failing me. Not to mention even if .161 was to be added, there is no reason why all of the IPs would have to be removed, as .161 could just be added in addition to these.

  • Sql Server Management Studio: Change Prefix or Suffix characters

    - by PhantomDrummer
    I have an instance of SSMS 2008, for which the option to edit data in a table doesn't work. If I right-click on any table in the Object Explorer and select 'Edit top 200 rows' I get an error dialog 'Invalid prefix or suffix characters. (MS Visual Database Tools)'. The error seems to be associated specifically with SSMS, not with SQL Server (because this SSMS instance gives the same error no matter what database I connect to, but I've verified I can connect to some of the same databases using SSMS on other machines without the error). (However, our firewall prevents me using SSMS on other machines for some crucial tasks, so I do need to fix the problem). Googling for the error suggests that I should change the prefix, suffix or escape character, but without any indication of how you can make that change in SSMS. I'd also note that I'm not aware of having done any customization on SSMS since installing it, so would be surprised at having to make such a change now. Does anyone have any idea what the error message means or what I can do about it? Or how I can change the prefix/suffix/escape characters if that is really the problem.

  • SSH hangs without password prompt

  • Intermittent "Lost connection to MySQL server at 'reading initial communication packet'"

    - by db2
    Our web environment consists of two servers. Web front-end. Dell PowerEdge R610, RHEL 5.5, Apache 2.2.17, php 5.2.14. Database server. Dell PowerEdge R710, Windows 2008 R2 Standard x64, MySQL 5.5.11-log x64. Normally these two work perfectly fine together. However, when I try to get them talking via a dedicated LAN on their secondary NICs (each machine has four of them), things get flaky. I have NIC #2 on both machines configured on the 172.16.1.0/24 subnet, with no gateway or DNS servers (obviously, since it's just those two systems), and I put the private IP address of each machine into the hosts file of the other. The routing tables on both machines look okay after I do this. I've tried this with both a crossover cable draped directly between the two NICs, and also via a dedicated vlan on the switch in the rack. In either case, I get intermittent connection problems. It's a fairly small percentage of connections that fail, but it's enough to cause a significant problem, and I have to switch back to the main network connection, which will contend with all the other traffic and hosts on the switch. The full error message that appears in the application log: SQLSTATE[HY000] [2013] Lost connection to MySQL server at 'reading initial communication packet', system error: 110 Am I doing something really dumb that's causing this to not work properly? Anything I can check in MySQL that would explain why it's failing to connect occasionally?

  • Forward all tracif from one IP to another Ip on OS X

    - by Josh
    This is related to this question I just asked... I have two IP address on my iMac I want to "bridge". I'm not sure what the proper terminology is... here's the situation. My iMac has a firewire connection to my laptop and an ethernet connection to the rest of my office. My laptop has an ip of 192.168.100.2 (on the firewire interface). My iMac has an IP of 192.168.100.1 on the firewire interface, and two IPs, 10.1.0.6 and 10.1.0.7, on it's ethernet interface. If I wanted to forward all traffic coming in from 192.168.100.2 on my OS X machine to go out on IP 10.1.0.7, and vice-versa, can this be done? I assume I would use the ipfw command. Essentially I want to "bridge" the firewire network to the ethernet network so my laptop can see all the machines on the 10.1 network, and all those machines can see my laptop at 10.1.0.7. Is this possible?

  • Stop Windows Domain Environment Caching Old Passwords?

I have noticed on my domain environment; the old Administrator password (before password expire).. The client machines have cached the old password and have the ability to bypass the new password by entering the old one..? Basically; I'm running a UAC enabled domain, which needs the administrator password to continue basic stuff; installations and such. The password for the administrator account has been changed due to expiration of said accounts password. By accident a fellow administrator typed the old password and still bypassed the UAC with what should have been the incorrect password. Is this a bug with the environment? or something that needs to be tweaked in the server sided settings?

  • Apache doesn't immediately notice a change in the document root

    - by Tom
    We use capistrano for website deployments and our Apache document root is a symlink to a particular code release. The deployment procedure switches the symlink from the old release to the new release as the final step of the deployment. We are migrating our webservers from real servers running RHEL 5.6 to Amazon EC2 virtual machines running Ubuntu 11.10 and the new servers are suffering from a problem where Apache doesn't immediately notice the change to it's document root when the symlink is switched. It can take a second or so (and I think I've even seen it take a couple of minutes). It's kind of like Apache has cached the physical path of the symlink for some time. Does anyone know some Apache settings I could look at to get it to "scan" for changes to it's served files quicker. Thoughts: I read that the disks on virtual machines are much slower (since they are network attached storage). Perhaps the filesystem cache somehow works differently too? If so, is there anything that can be done? The website runs PHP code. Perhaps there is some PHP config differences between RHEL and Ubuntu? I checked realpath_cache_ttl but both servers have it commented out: e.g. ; Duration of time, in seconds for which to cache realpath information for a given ; file or directory. For systems with rarely changing files, consider increasing this ; value. ; http://www.php.net/manual/en/ini.core.php#ini.realpath-cache-ttl ;realpath_cache_ttl = 120 We do use the APC opcode cache but don't think it's the issue due to experimentation. The PHP code is in different file paths for each deployment and we ensure stat=1. Here is a similar question that is very interesting: 294107 - but doesn't provide an answer for me. One solution would be to reload Apache everytime we modify the document root symlink. I'll do this if we can't find another solution.

  • "postgres blocked for more than 120 seconds" - is my db still consistent?

    - by nn4l
    I am using an iscsi volume on an Open-E storage system for several virtual machines running on a XenServer host. Occasionally, when there is a very high disk I/O load on the virtual machines (and therefore also on the storage system), I got this error message on the vm consoles: [2594520.161701] INFO: task kjournald:117 blocked for more than 120 seconds. [2594520.161787] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162194] INFO: task flush-202:0:229 blocked for more than 120 seconds. [2594520.162274] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162801] INFO: task postgres:1567 blocked for more than 120 seconds. [2594520.162882] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. I understand this error message is caused by the kernel to inform that these processes haven't been run for 120 seconds, most likely because a disk access to the storage system has not yet been processed. But what is the effect on the processes. For example, will the postgres process eventually write its data when the storage system is idle again after a few minutes, so that all data is still consistent? Or will it abort the write, leaving some tables in an inconsistent state? I certainly expect that the former should be the case - if the disk access is slow, postgres (or any other affected process) should just wait as long as it takes. I can live with the application hanging for a few minutes. But if there is a chance for data corruption then any of these errors is really bad news. Please advise what to do here.

  • Domain authentication over OPEN wireless pre-logon (Windows 7 Pro) - No logon servers avail

    - by Shadow00Caster
    I have a plethora of laptops that are joined to an AD domain. I have an enterprise wireless system setup, the users of these laptops will be using an OPEN unsecured SSID which will ultimately have a captive portal that uses Radius-AD auth and firewall rules to allow access pre-captive portal auth to the proper ip's/ports of DC's etc for auth etc. I already have other laptops/users connecting to another SSID with 802.11x and SSO, all works perfectly pre-logon etc. My problem is with this open network, for some reason I cannot get the machines to auth to AD. The laptops connect to the wireless network, I confirm this on the controller and can ping the laptop at startup. I sharked the wires on the 2 DC's that these machines auth to, I can see a DNS SOA update from a laptop im testing with and can ping that test laptop from both DC's. When I try to logon, "There are currently no logon servers available to service the logon request." The shark shows no incoming connections to either DC even though the laptop is connected and pingable. Any help is greatly appreciated.

  • Clustering/load balancing for cluster unaware applications

    - by AaronLS
    Forgive me if I use any of these terms incorrectly. I am wondering if there is any kind of software that would allow my two "join" two computers together such that a cluster unaware application could utilize their combined computing resources? By "cluster unaware" I mean an application that isn't designed to share work across multiple services. My understanding is that clustering is enabled by the specific application by it's architecture, such that messaging with multiple instances of the application coordinate the sharing of work. Instead I am looking for something that enables clustering at the OS or virtualization level, so that any application could essentially be clustered. Failing that, I am also wondering about the following scenario: We have 3 different applications we will call A, B, and C. We have 2 single core computers. At any given time lets say that any combination of those applications will be CPU intensive. In cases where only 2 of those apps are very active, have one of them moved over to a different server. In a nutshell, some sort of dynamic automatic shuffling of the application's load. I have heard of virtual machines that can be migrated across physical machines while live, but I am wondering if this can be done automatically in response to an application's or VM's CPU activity?

  • Internet connection & IIS stopped on windows xp after VMware server 2 installation

    - by Eduardo Xavier
    Hi, I'm running a local network. My IP ranges from 192.168.1.2 to 192.168.1.15. All IP are static ones. And my router's IP is 192.168.1.1 and I provide it as default gateway and preferred DNS server on client machines. Everything worked fine on this scenario. I could use internet and reach services on other machines. BUT I have installed VMware server 2 on the windows XP to host windows 2003 Virtual Machine (VM). I set the following configuration: Windows XP's => 192.168.1.11. Windows 2003 => 192.168.1.12. (virtual machine) This approach worked just fine as it used to work with Microsoft Virtual PC. I can access mysql & IIS websites on the windows 2003 virtual machine. BUT two things doesn't work anymore on the Windows XP: internet connection - but I can see the MAC address on the wireless router IIS - Ping on 127.0.0.1 it's ok as I can hit localhost:8222 nor localhost Does anyone knows how to fix any of this? (at least the internet connection)

  • How to add URL's to wiki (MediaWiki) powered documentation?

    - by Ian Boyd
    We have an internal company wiki. The wiki engine being used is MediaWiki, the wiki engine that runs Wikipedia. Some of it contains IT stuff. One of the things i want want to have are hyperlinks to the various virtual machines. An example of a command, as it needs to run, is: vmrc://solo.avatopia.com:5901/Windows 2000 Server My first thought was to convert the URL into a link: [vmrc://solo.avatopia.com:5901/Windows 2000 Server] But the content renders literally as above: with the square brackets and all. Testing with other URL protocols: [http://solo.avatopia.com] [ftp://solo.avatopia.com] [ldap://solo.avatopia.com] [vmrc://solo.avatopia.com] Only the first two work, and are converted to hyperlinks. The other two remain as liternal text. How can i add URLs to MediaWiki powered documentation? Original Question We have an internal company wiki. The wiki engine being used is MediaWiki, the wiki engine that runs Wikipedia. Some of it contains IT stuff. One of the things i want want to have are hyperlinks to the various virtual machines. An example of a command, as it needs to run, is: \\solo\VMRC Client\vmrc.exe solo.avatopia.com:5901/Windows 2000 Server If launching from a command prompt, you have to quote the spaces: C:\>"\\solo\VMRC Client\vmrc.exe" solo.avatopia.com:5901/"Windows 2000 Server" My first thought in converting the above for use on our wiki-site, is to simply HTML-ify it: file://\\solo\VMRC Client\vmrc.exe solo.avatopia.com:5901/&quot;Windows 2000 Server&quot; but MediaWiki only converts file://\solo\VMRC to a hyperlink, the remainder is text. i've tried other random things, including enclosing the URL in square brackets. What is the correct answer? i don't want to happen to randomly stumble on some format that happens to work today, and breaks in the future.

  • Problem linking two Cisco routers with a static route

    - by Chris Kaczor
    I'm trying to link two Cisco routers with a static route and I haven't been able to get it working as expected. Here is the basic setup: Router 1 - WRV210 - 192.168.1.1 - connected to cable modem Router 2 - RV120W - 192.168.2.1 I already have several machines on Router 1 that are working and I want to setup Router 2 with a few other machines on the different subnet. Here is what I've configured: Connected the WAN port on Router 2 to a LAN port on Router 1 Configured Router 1 to give 192.168.1.2 to Router 2 via DHCP Configured Router 1 with a static route (192.168.2.0 mask 255.255.255.0) to 192.168.1.2 using the LAN & Wireless interface Disabled the firewall on Router 2 (since it is covered by Router 1) Configured Router 2 to "Router" mode instead of "NAT" mode Configured Router 2 with a static route (192.168.1.0 mask 255.255.255.0) to 192.168.1.1 using the WAN interface From the research I've done I think that should be enough but things aren't working exactly as expected: Router 2 can ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) A machine on Router 2 can ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) ping 192.168.1.1 and 192.168.1.101 (a machine on router 1) Router 1 can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) A machine on Router 1 can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) can NOT ping 192.168.2.1 or 192.168.2.101 (a machine on router 2) Router 1 and a machine on Router 1 can ping 192.168.1.2 (Router 2 itself) I'm confused as to why Router 1 cannot talk to the 192.168.2.0/255.255.255.0 subnet. Any help would be greatly appreciated.
