• Backup program for Windows using non-proprietary format?

  - by Cristi Diaconescu

  I'm looking at the various local backup programs for windows, and I was wondering which of them use a non-proprietary backup format? By non-proprietary, I mean I want to be able to access at least the latest version of the backed up files either directly, or by using an open-standard format like zip/7z/rdiff... The other thing I'm looking for in a backup program is the ability to create incremental backups. What I have found so far: SyncBack copies files as-is, using separate directories for versioning pretty much the same for all the 'roll you own' task scheduler + rsync/xcopy32/robocopy/MS SyncToy/etc solutions GFI Backup appears to be using Zip files, at least in their 'Business' version, not sure about the free 'Home' version. Didn't try it yet, but it's next on my list. Mozy (!) supports local backup starting with v 2.0 and basically provides a 2nd local copy on a separate partition. Subjectively, it feels slow and resource intensive (I think it took more than a week to finish the first local backup of ~ 300 GB), and does not appear to offer file versioning (arguably, you can get older file versions online). On the positive side, it looks like the local backup is integrated in the restore process which was traditionally a masochistic experience (and this goes for any online backup provider). Other suggestions? I favor ease of use over tons of options (e.g. SyncBack is very flexible but it offers sooo many ways to shoot yourself in the foot...)

• Network Logon Issues with Group Policy and Network

  - by bobloki

  I am gravely in need of your help and assistance. We have a problem with our logon and startup to our Windows 7 Enterprise system. We have more than 3000 Windows Desktops situated in roughly 20+ buildings around campus. Almost every computer on campus has the problem that I will be describing. I have spent over one month peering over etl files from Windows Performance Analyzer (A great product) and hundreds of thousands of event logs. I come to you today humbled that I could not figure this out. The problem as simply put our logon times are extremely long. An average first time logon is roughly 2-10 minutes depending on the software installed. All computers are Windows 7, the oldest computers being 5 years old. Startup times on various computers range from good (1-2 minutes) to very bad (5-60). Our second time logons range from 30 seconds to 4 minutes. We have a gigabit connection between each computer on the network. We have 5 domain controllers which also double as our DNS servers. Initial testing led us to believe that this was a software problem. So I spent a few days testing machines only to find inconsistent results from the etl files from xperfview. Each subset of computers on campus had a different subset of software issues, none seeming to interfere with logon just startup. So I started looking at our group policy and located some very interesting event ID’s. Group Policy 1129: The processing of Group Policy failed because of lack of network connectivity to a domain controller. Group Policy 1055: The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following: a) Name Resolution failure on the current domain controller. b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller). NETLOGON 5719 : This computer was not able to set up a secure session with a domain controller in domain OURDOMAIN due to the following: There are currently no logon servers available to service the logon request. This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator. E1kexpress 27: Intel®82567LM-3 Gigabit Network Connection – Network link is disconnected. NetBT 4300 – The driver could not be created.

• Poor NFS Performance: OpenFiler

  - by Safin09

  Good Day Everyone, I have an issue with OpenFiler, a Linux-based operating that converts a computer system into a SAN/NAS appliance. Here is the problem. In my environment we have two Netapp Storevault 500 appliances that I normally perform backups to a NFS share. There are two backup cronjobs that use ghettoVCB to backup two groups of VM's. One group is a pool of 3 VMs. This takes 13 mins to complete. A second job that backups a pool of 5 VMs to a 2nd Storevault appliance which takes 2 hours. We then installed Openfiler on a old server that has 2 core Xeon processors. There is a software RAID 5 process in place. When performing the same backups to a NFS Openfiler share, the first backup job, which takes 13 mins, takes around 4 hours. The second backup job, which takes 2 hours, takes almost 10 hours to complete. This is unacceptable!!!! Especially considering the strain placed on the host ESX Server. I assumed that because of the software RAID 5, the overhead on the CPU explained the long backup times. I then installed Openfiler on a 2nd server, an IBM x306 machine which has a P4 Intel processor. This time no software RAID or any RAID at all. A single 750GB hard drive that contained the OS and the rest of the disk uses to backup VMs to a NFS share. I performed the first backup job of the pool of 3 VMs. This time the backup job took 1 and 1/2 hours to complete instead of 13 mins!!!!!!!!!! Is Openfiler simply poor at being an NFS Server!!!!!!!!!!!!! Has anyone else had these issues with Openfiler?

• Embedded Spotlight does not function in Outlook 2011

  - by syntaxcollector

  I have a rather strange problem. I manage a network of about 35 Mac, and we all recently switched from Mail.app to Outlook 2011 (Please don't debate this, I've already had this conversation ad nauseum) We are using network home directories (NHD) server from a Windows file server over the SMB protocol. The problem I'm having is Spotlight does not function inside of Outlook. But ONLY inside of Outlook. The global Spotlight can find all email and contacts with Outlook, but the embedded Spotlight cannot. As a test, I took one of my users and switched them from a network home directory to a portable home directory (PHD) (this means the home folder was copied to the local hard drive). This resulted in a working Spotlight within Outlook, as soon as I switched the user back to an NHD, however, it stopped working. I have already tried erasing the Spotlight index and killing the process to force re-indexing. I have exhausted all Spotlight troubleshooting, and since the global is working that is obviously not the issue. I believe it has something to do with the Spotlight plugin Microsoft wrote that is located in /Library/Spotlight. Any ideas?

• How can I close a port that appears to be orphaned by Xvfb?

  - by Jim Fiorato

  I'm running Xvfb on a FC8 Amazon EC2 image. On occasion Xvfb will crash (unable at the moment to find out the reason for the crash), and after crashing the TCP port will appear to be orphaned. I'm unable to get a PID to kill any process that may be using it. I'm starting Xvfb with: Xvfb :7 -screen 0 1024x768x24 & Examples of what I'm working with are below, the Xvfb port is (was) 6007: # netstat -ap Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 *:ssh *:* LISTEN 1894/sshd tcp 0 0 *:6007 *:* LISTEN - tcp 0 352 ip-10-84-69-165.ec2.int:ssh c-71-194-253-238.hsd1:51689 ESTABLISHED 2981/0 udp 0 0 *:bootpc *:* 1817/dhclient udp 0 0 *:bootpc *:* 1463/dhclient Active UNIX domain sockets (servers and established) Proto RefCnt Flags Type State I-Node PID/Program name Path unix 2 [ ] DGRAM 871 668/udevd @/org/kernel/udev/udevd unix 2 [ ACC ] STREAM LISTENING 5385 1880/dbus-daemon /var/run/dbus/system_bus_socket unix 6 [ ] DGRAM 5353 1867/rsyslogd /dev/log unix 2 [ ] DGRAM 11861 2981/0 unix 2 [ ] DGRAM 5461 1974/crond unix 2 [ ] DGRAM 5451 1904/console-kit-da unix 3 [ ] STREAM CONNECTED 5438 1880/dbus-daemon /var/run/dbus/system_bus_socket unix 3 [ ] STREAM CONNECTED 5437 1904/console-kit-da unix 3 [ ] STREAM CONNECTED 5396 1880/dbus-daemon unix 3 [ ] STREAM CONNECTED 5395 1880/dbus-daemon unix 2 [ ] DGRAM 5361 1871/rklogd # lsof -i COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME dhclient 1463 root 3u IPv4 4704 UDP *:bootpc dhclient 1817 root 4u IPv4 5173 UDP *:bootpc sshd 1894 root 3u IPv4 5414 TCP *:ssh (LISTEN) sshd 2981 root 3u IPv4 11825 TCP ip-10-84-69-165.ec2.internal:ssh->c-71-194-253-238.hsd1.il.comcast.net:51689 (ESTABLISHED) Attempting to force the port closed with iptables doesn't seem to work either. iptables -A INPUT -p tcp --dport 6007 -j DROP I'm at a loss as to how to reclaim/free the port. From what I can tell, this port will remain in this state until the EC2 instance is shut down. So, how can I close this port so I can restart Xvfb?

• How can the little guys effectively learn and use puppet?

  - by drumfire

  Six months ago, in our not-for-profit project we decided to start migrating our system management to a Puppet controlled environment because we are expecting our number of servers to grow substantially between now and a year from now. Since the decision has been made our IT guys have become a bit too annoyed a bit too often. Their biggest objections are: "We're not programmers, we're sysadmins"; Modules are available online but many differ from one another; wheels are being reinvented too often, how do you decide which one fits the bill; Code in our repo is not transparent enough, to find how something works they have to recurse through manifests and modules they might have even written themselves a while ago; One new daemon requires writing a new module, conventions have to be similar to other modules, a difficult process; "Let's just run it and see how it works" Tons of hardly known 'extensions' in community modules: 'trocla', 'augeas', 'hiera'... how can our sysadmins keep track? I can see why a large organisation would dispatch their sysadmins to puppet courses to become puppet masters. But how would smaller players get to learn puppet to a professional level if they do not go to courses and basically learn it via their browser and editor?

• Reloading NAT configuration on a running VMWare Server 2.0.2

  - by Jonathan Clarke

  I have a server running VMWare Server 2.0.2. The host is Debian Lenny. I have 15-20 virtual machines running, all attached to a single NAT network (named vmnet8). I have configured VMWare's NAT (the vmnet-natd daemon) to forward some incoming to ports to one of the VMs, since it hosts some publicly accessible services. I did this via the file /etc/vmware/vmnet8/nat/nat.conf by adding lines like the following: 80 = 192.168.100.100:80 This works great, I can reach the web server on the VM at 192.168.100.100 by connecting to the host's IP address. Sometimes, I need to add port redirections to this NAT configuration. So, I add a line to the configuration file. Now for the question. How do I make the natd process take this new configuration into account? Clearly, restarting the host machine does take it into account, and the newly added port is forwarded. However, this is not an option on this server, so how should one do this without restarting the whole host? Thanks for any ideas!

• Exim rejects recipient address on my domain

  - by Nicolas

  Hi, I have a dedicated server (debian) on which I have installed Exim and Dovecot. Everything worked fine until around a month ago. I tried to reinstall and reconfigure exim but I keep having all the incoming emails rejected. Outlook says: A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [email protected] SMTP error from remote mail server after RCPT TO:: host mail.mydomain.com [94.76.##.##]: 550 relay not permitted GMAIL: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 relay not permitted (state 14). On the server side, my rejectlog file shows: 2011-01-04 17:09:21 H=mail-qw0-f53.google.com [209.85.216.53] F=<####@gmail.com rejected RCPT : relay not permitted ... and the mainlog file: 2011-01-04 17:00:01 1PaAEr-0007vN-DX <= root@ETC_MAILNAME U=root P=local S=869 2011-01-04 17:00:01 1PaAEr-0007vN-DX ** root@etc_mailname: Unrouteable address 2011-01-04 17:00:01 1PaAEr-0007vY-Kn Error while reading message with no usable sender address (R=1PaAEr-0007vN-DX): at least one malformed recipient address: root@ETC_MAILNAME - malformed address: _MAILNAME may not follow root@ETC 2011-01-04 17:00:01 1PaAEr-0007vN-DX Process failed (1) when writing error message to root@ETC_MAILNAME (frozen) 2011-01-04 17:09:21 no IP address found for host MAIN_RELAY_NETS (during SMTP connection from mail-qw0-f53.google.com [209.85.216.53]) 2011-01-04 17:09:21 H=mail-qw0-f53.google.com [209.85.216.53] F=<####@gmail.com rejected RCPT : relay not permitted then after the message becomes frozen: 2011-01-04 17:28:44 1PaAEr-0007vN-DX Message is frozen Thank you for your help, any idea/comment is welcomed as I am really running out of idea to fix this issue, Nicolas. Oh and the PHP mail() function does not do anything as well, would it be linked to? I think mail() uses sendmail from my php.ini.

• Network monitoring tools with API features

  - by Kev

  We use ks-soft's Advanced Hostmonitor package to monitor around 2000 items on our network. We think it's great, the chap that supports it is fantastic, the product is fast, stable and mature but I feel as as we grow as a company it's beginning to show some friction points in the area of integration with our back office admin systems. One of the things we'd like to do is be able to add new tests to whatever monitoring tool we use via an API. For example, when orders for servers come from our retail interface, the server gets built automatically, and as part of the automated build process we'd like to automatically add new tests to the network monitoring systems. Hostmonitor has some support for this via a feature called HM Script but we're starting to encounter some speedbumps - we can't add new operators/users we can't define new "Action Profiles" - these are the actions to be taken when a test goes good or bad. What we love about hostmonitor though are the Action Profiles. For example if a Windows IIS box goes bad our action profile for a bad test does something like: Check host again (one time) Wait another 30 seconds then test again Try restart app pool on remote machine (up to two times) Send an email to ops about the restart failure Try restarting IIS on remote machine (up to four times) Page duty admin (up to 5 times - stops after duty admin ACKS alert) Page backup duty admin (5 times - stops after duty admin ACKS alert) I'm starting to look around at other network monitoring tools and I'm looking for: a comprehensive API to be able to add/remove/control tests/test "action profiles"/operators (not just plugins, we need control and admin interfaces) the ability to have quite detailed action/escalation profiles (and define these via an API) I've looked at Nagios and Icinga but Ican't seem to glean from their documentation whether we could have these features or not, or if we could, how much work would be involved to implement/customise. Can anyone provide any advice, guidance or experiences?

• Lion server profile manager, device enrollment doesn't work

  - by user964406

  I am in the process of setting up Lion Servers profile manager to manage iPads on our local school network. I don't need to manage them while they are outside the network. I have successfully had it working on my personal network. The school network is behind a proxy which we have no control over. I can get the iPads to view the mydevices page and install a trust cert. I have managed to get an iPad to successfully install the remote management profile. After this the profile manager bugs out. It will list the active task of 'new device (sending)' but it's unable to complete the task. If I click on the device on profile manager and try any of the actions out they will all fail to complete. I am using the auto generated certificates and this works if I bring the server and iPad outside of the school network. Shortly after device enrollment the system log on the Lion server reports the following Replaced the actual ip address with INTERNALIP Jun 4 08:40:53 mini sandboxd[760] ([778]): applepushservice(778) deny network-outbound INTERNALIP:8080 Jun 4 08:40:53 mini sandboxd[760] ([778]): applepushservice(778) deny network-outbound INTERNALIP:8080 Jun 4 08:40:53 mini applepushserviced[778]: Got connection error Error Domain=NSPOSIXErrorDomain Code=1 "The operation couldn\u2019t be completed.

• 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..

• Apache HTTPD - Segmentation fault when loading mod_jk module

  - by hansengel

  I just set up mod_jk with my Apache httpd 2.0.52 installation, but now when I try to start Apache, it has a segmentation fault. I've checked that I am using the mod_jk compiled for 2.0.x.. built against the same version I have, in fact. I've also verified that the path I'm giving to LoadModule is correct, and the permissions and the ownership of the file are the same as the rest of the modules'. When I remove the "LoadModule" command for mod_jk from my httpd.conf, there is no segmentation fault. Nothing shows in Apache's error logs. I have tried restarting the server with this module using both service httpd restart and httpd. These are the last few lines returned of strace httpd -X: gettimeofday({1292100295, 434487}, NULL) = 0 socket(PF_INET6, SOCK_STREAM, IPPROTO_IP) = -1 EAFNOSUPPORT (Address family not supported by protocol) socket(PF_NETLINK, SOCK_RAW, 0) = 3 bind(3, {sa_family=AF_NETLINK, pid=0, groups=00000000}, 12) = 0 getsockname(3, {sa_family=AF_NETLINK, pid=22378, groups=00000000}, [12]) = 0 time(NULL) = 1292100295 sendto(3, "\24\0\0\0\26\0\1\3\307\342\3M\0\0\0\0\0\305\333\267", 20, 0, {sa_family=AF_NETLINK, pid=0, groups=00000000}, 12) = 20 recvmsg(3, {msg_name(12)={sa_family=AF_NETLINK, pid=0, groups=00000000}, msg_iov(1)=[{"<\0\0\0\24\0\2\0\307\342\3MjW\0\0\2\10\200\376\1\0\0\0"..., 4096}], msg_controllen=0, msg_flags=0}, 0) = 664 recvmsg(3, {msg_name(12)={sa_family=AF_NETLINK, pid=0, groups=00000000}, msg_iov(1)=[{"\24\0\0\0\3\0\2\0\307\342\3MjW\0\0\0\0\0\0\1\0\0\0\10\0"..., 4096}], msg_controllen=0, msg_flags=0}, 0) = 20 close(3) = 0 socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 3 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Process 22378 detached Has anyone had a similar problem using Apache 2.0.52 with mod_jk?

• Problem with creation of scheduled task from IIS6 on SR2003

  - by Morten Louw Nielsen

  Hi, I have also posted this question on stackoverflow, but will also try here, since it might be more system-related I am writing a webapplication using .NET. The webapp creates scheduled tasks using the System.Diagnostics.Process class, calling SCHTASKS.EXE with parameters. I have changed the identity on the app pool, to a specific domain user. The domain-user is local administrator on all the four webservers. From webserver01 I am creating tasks on webserver01 to webserver04. It works perfect for 3-5 days, but then it breaks. It gives me the following errormessage in a messagebox: "The application failed to initialize properly (0xc0000142). Click on OK to terminate the application." If I have the system in the broken state, and I change the identity of the app pool to Domain administrator, it works. As I change it back to my domain-user, it breaks again. If I reboot the server, it works again for the same amount of days, but will break again. It seems like a permission-related problem. I just don't understand why it works sometimes, and sometimes doesn't. I hope someone outthere has seen this problem! Looking forward to hear from you! Kind regards, Morten, Denmark

• Bacula v5.0.2 Windows Installation Issues

  - by JohnyD

  First off, I am very new to Bacula but I'm very intriqued from what I've read. I'm looking to set up Bacula 5.0.2 on a Windows 2008 R2 server. I've run the installer and at the end it asks me to configure DIR name, DIR password, DIR Address. Windows documentation is somewhat hard to come by and I'm not certain what exactly I'm supposed to enter here. Do I need to create a local account that matches this info? Will the installation process create the account for me? Will this be the account that handles the FD daemon/service? I'm also not certain if Address means network location or local direcory. I apologize for my ignorance. Currently I'm trying to use the following information: Name: john pass: john address: thin1 (server name although I have also tried thin1.fqdm.local and 10.0.0.104) This info allows for the installer to complete successfully. However, when I run the BAT it hangs at, "Connecting to Director thin1:9101". The Bacula File Service is currently running under the local system account. What am I doing wrong? What do I have yet to do? Once I get this working properly I assume I will need to install clients on all my Windows boxes? Also, this is a 64-bit cpu but I am installing the 32-bit client. Are there any issues with this? Should I be using the 32-bit client? Thanks very much for the help.

• BSOD trying to migrate Windows XP from a physical to a virtual machine

  - by pauldoo

  I am attempting to migrate a Windows XP Home installation from a physical machine to a virtual machine. The physical machine has two hard disks; the first is 250GB containing the "C:", the second is 1TB containing "D:". I'd like to create a new virtual machine stored on the D:, which is a copy of the Windows XP Home installation that is currently on the C:. (This will leave the 250GB drive clear for me to install a fresh copy of Windows 7, and still be able to access the old XP installation if necessary.) The first method I tried was to follow the instructions here: http://www.virtualbox.org/wiki/Migrate_Windows I booted up from an Ubuntu Live CD in order to execute the Linux commands whilst the Windows system wasn't running. With this method the virtual machine would always blue screen on startup with a "STOP 0x0000007B" message. The instructions above say to try a "repair install" using the Windows XP disc. Unfortunately for me my XP disc is scratched and will not boot so I was unable to try a repair install. The second method I tried was to use "VMWare Converter Standalone Client". This tool executed without any errors, but again produced a virtual machine that blue screens on startup with the same "STOP" message. Are there any other methods to move the Windows XP installation into a virtual machine? I think next I will try some more manual process to create the cloned virtual machine. I think I will try installing a fresh copy of Windows XP to a virtual machine, then once that is booting OK I will ntfsclone the source C: partition over the top. Perhaps this will fix the booting problems if the issue is related to the MBR or partition table in some way.

• Run Explorer in SYSTEM account on Windows Vista or 7 using Sysinternal’s psexec tool?

  - by Rob

  Has anyone been successful at launching an instance of Windows Explorer in the SYSTEM account on Windows Vista or 7? It is possible to do this on XP, but I haven't been able to get it to completely work in Vista or 7. Trying to launch Explorer as SYSTEM into session 1 (my user session) results in Explorer exiting immediately and returning an error code of 1. I can launch Explorer as SYSTEM into session 0 with the following command: psexec -i 0 -s explorer That will create an instance of explorer running as SYSTEM with a taskbar and start menu on the hidden session 0 desktop, but won't let you open a file browser window. If you switch to the hidden session 0 desktop and try to open an Explorer window from there to browse files, the following error message appears: "The server process could not be started because the configured identity is incorrect. Check the username and password." I have set the following registry key to 1 for my user account and the SYSTEM account: \Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\SeparateProcess There has got to be a way to make this work? If it is not possible, can anyone explain why? -Rob

• Server 2008 Disk Management Hangs

  - by Payson Welch

  So I have looked everywhere for the solution to this and have tried many things. There is one post on SE related to this and I tried the suggested answer but I am still having problems. We have a server running Server 2008 R2 Standard x64. I need to increase the space of C: since the free space is running very low. However when I open Server Manager and try to go to the "Disk Management" snap-in it just hangs. There is a status message on the bottom of the window that says "Connecting to Virtual Disk Service...". Here are the steps I have taken: Ran sfc /scannow Set all of the drives to be dirty and rebooted so that they would be scanned Executed chkdsk /f /r /b /v on all of the drives. Checked for Windows updates (none). Verified that the services "Virtual Disk", "RPC Procedures" and "Plug and Play" are all running. One symptom is that the service "Virtual Disk" does not cleanly shut down. I receive a message about the process being unexpectedly terminated when I try to stop or restart it. Also I cannot find anything relevant in the event logs. Any ideas or suggestions?

• SSH session closing whilst virtualenv session stays open (I think)

  - by ing0

  I've been developing some sites using Flask recently (running on debian within a virtualenv), and when I am testing I can run it on a port, let's say post 5000. So I run the script like so: . env/bin/activate <- go into virtual environment python file.py <- run python script And I will be given this message: Running on http://0.0.0.0:5000/ So this all works great and I can access my site on this port fine. However... my rubbish ISP always does this thing where it resets something around 1am every morning. I have no idea what this is, everything runs like normal but I always get disconnected from any SSH sessions open. This leaves it running and all I can do is call: lsof -i Which will show me the process but if I kill it and then rerun it things get weird. The: Running on http://0.0.0.0:5000 message still shows but I cannot connect to it anymore. I've tried changing the port number and it seems the only thing that works is trying again later on or on another day. Now I'm assuming that something on my server resets inbetween these times and I would like to think it was maybe that virtualenv session timing out, but I cannot find out how to do this manually, does anyone know?

• Routing multiple static IPs from ISP at the cable modem?

  - by Jakobud

  I'm taking over IT responsibilities for a previous IT guy. We have a 50mb cable modem connection from Comcast along with 5 static IP addresses: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 We are in the process of replacing our firewall machine. Currently the firewall box is the only thing connected to the cable modem. However the cable modem has multiple ethernet ports on it, similarly to a router. I have assembled a new firewall machine and its time to start testing and configuring it. So that means that I also need it plugged into the cable modem (remember it has multiple ethernet ports on it). So now with multiple computer plugged into the cable modem, how does the cable modem know where to route the traffic? If some request on the internet is made to XXX.XXX.XXX.181, which goes to our cable modem, how does the cable modem know which connected computer that traffic is supposed to be sent? Looking at the web interface for the cable modem, there doesn't seem to be anything special setup on it with regards to routing or NATing IP addresses. Is that because when there is only one computer connected to the modem, all traffic is sent to it by default? Now that I am going to (temporarily) have multiple computers plugged into the cable modem, do I need to specify routing or NAT rules on the modem itself? I am going to speak to Comcast about this next, but I figured I'd ask here first just so I can get a better grasp on how this type of thing generally plays out.

• Computer specs for a large database

  - by SpeksETC

  What sort of computer specs (CPU, RAM, disk speed) should I use for running queries on a database of 200+ million records? The queries are for a research project, so there is only one "user" and only one query will be running at a time. I tried it on my own laptop with SQL Server with an i3 processor, 2GB RAM, 5400 RPM disk and a simple query didn't finish even after 8+ hours. I have an option to connect a SSD via eSata and upgrade to 4GB RAM, but not sure if this will be enough... Thanks! Edit: The database is about 25 GB and the indexes are not setup properly. When I tried to add an index, I let it run for about 8 hours and it still hadn't finished so I gave up. Should I have more patience :)? In general, the queries will run once in a while and its ok even if it takes a couple hours to complete.... Also, the queries will produce probably about 10 million records which I need to process using Stata/Matlab and I'm concerned that my current laptop is not strong enough, but unsure of the bottleneck....
