pfsense 2.0 traffic priority - set full priority for single host

- by Waxhead

I have a network with several computers all on the same network and since I have very limited bandwidth I would like to prioritize traffic almost like a CPU scheduler prioritize processes. Example: Computer A: Used for webstuff: YouTube, downloads, news, emails etc. Computer B: Transferring files over HTTP Computer C: Transferring files over ftp, rsync whatever What I would like to do is to give A up to for example 90% of the available bandwidth IF A requires it. The leftovers (10%) is divided between B and C (5% each if both is busy) If A is not utilizing all bandwidth then of course B and C should share the full bandwidth (50% each as long as both are maxing out their bandwidth). All computers are on the same network (192.168.1.0 - 192.168.1-10 for example). Appreciate if anyone could shed some light on how I should set up my network to achieve this. To be honest I actually need a step by step guide on how I should set this up. Network setup: (ADSL modem configured in bridge mode (1500kbps/300kbps)) [ADSL modem (bridge)]<-[pfsense2.0]<-[switch]<-[Computer A,B,C...etc]

Windows Update and lsass.exe

- by David

I have a brand new installation of Windows XP (SP1 or older). I installed Norton AntiVirus, Firefox, Putty, and Cygwin. No other software is present. Windows Update finds the following 64 updates: KB905760, KB978262, Internet Explorer 8, KB71961, KB954155, KB968816, KB923561, KB950762, KB949402, KB950974, KB951376, KB951748, KB952004, KB952954, KB955069, KB956572, KB956802, KB956803, KB956844, KB958470, KB958869, KB959426, KB960803, KB960859, KB961501, KB969059, KB970238, KB970238, KB971032, KB971468, KB971657, KB972270, KB973507, KB973815, KB973904, KB974112, KB974318, KB974392, KB975025, KB975560, KB975561, KB975713, .......) When these updates are applied, the system reboots to a black screen with two error messages. The first error message says: lsass.exe - Application Error The application failed to initialize properly (0xc00000142). Click on OK to terminate the application. The second error message says: services.exe - Application Error The application failed to initialize properly (0xc00000142). Click on OK to terminate the application. I then proceed to boot into Safe Mode, use System Restore, and everything works fine again until the 64 updates re-appear in Windows Update. I can see two options: disable Auto-Updates or install each of the 64 updates one at a time until finding the troublesome update. Does anyone have any better ideas?

How to stop Firefox on an SSD from freezing when using the search box or submitting a form?

- by sblair

Firefox usually freezes for about a second whenever I search for something from the toolbar search box, when submitting a form, or when clearing the search box history. I suspect it has something to do with the auto-complete feature. Using Windows 7's Resource Monitor, the problem seems to be from the file: C:\Users\<username>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\formhistory.sqlite-journal I believe this is a temporary file which caches database writes. The following screenshot shows the very high response times from six different searches, and that the queue length on drive C shoots off the scale: My Firefox profile is on an Intel X25-M G2 SSD. The problem doesn't seem to occur if I create a new profile on a hard disk drive. However, I'd like to know why the problem exists on the SSD in the first place (because it's an annoying problem which contradicts the reason I bought an SSD, and it might happen with other applications too), and how to prevent it. It still occurs if Firefox is started in safe mode, and with the recent beta versions. Updates: VACUUMing the Firefox profile databases does not help with this problem. The SSD Optimizer in the Intel SSD Toolbox does not help either.

Is there a utility to visualise / isolate and watch application calls

- by MyStream

Note: I'm not sure what to search for so guidance on that may be just as valuable as an answer. I'm looking for a way to visually compare activity of two applications (in this case a webserver with php communicating with the system or mysql or network devices, etc) such that I can compare the performance at a glance. I know there are tools to generate data dumps from benchmarks for apache and some available for php for tracing that you can dump and analyse but what I'm looking for is something that can report performance metrics visually from data on calls (what called what, how long did it take, how much memory did it consume, how can that be represented visually in a call stack) and present it graphically as if it were a topology or layered visual with different elements of system calls occupying different layers. A typical visual may consist of (e.g. using swim diagrams as just one analogy): Network (details here relevant to network diagnostics) | ^ back out v | Linux (details here related to firewall/routing diagnostics) ^ back to network | | V ^ back to system Apache (details here related to web request) | | ^ response to V | apache PHP (etc) PHP---------->other accesses to php files/resources----- | ^ v | MySQL (total time) MySQL | ^ V | Each call listed + time + tables hit/record returned My aim would be to be able to 'inspect' a request/range of requests over a period of time to see what constituted the activity at that point in time and trace it from beginning to end as a diagnostic tool. Is there any such work in this direction? I realise it would be intensive on the server, but the intention is to benchmark and analyse processes against each other for both educational and professional reasons and a visual aid is a great eye-opener compared to raw statistics or dozens of discrete activity vs time graphs. It's hard to show the full cycle. Any pointers welcome. Thanks!

Varnish does not start properly (crashes after startup) with no error messages

- by Matthew Savage

I am running Varnish (2.0.4 from the Ubuntu unstable apt repository, though I have also used the standard repository) in a test environment (Virtual Machines) on Ubuntu 9.10, soon to be 10.04. When I have a working configuration and the server starts successfully it seems like everything is fine, however if, for whatever reason, I stop and then restart the varnish daemon it doesn't always startup properly, and there are no errors going into syslog or messages to indicate what might be wrong. If I run varnish in debug mode (-d) and issue start when prompted then 7 times out of time it will run, but occasionally it will just shut down 'silently'. My startup command is (the $1 allows for me to pass -d to the script this lives in): varnishd -a :80 $1 \ -T 127.0.0.1:6082 \ -s malloc,1GB \ -f /home/deploy/mysite.vcl \ -u deploy \ -g deploy \ -p obj_workspace=4096 \ -p sess_workspace=262144 \ -p listen_depth=2048 \ -p overflow_max=2000 \ -p ping_interval=2 \ -p log_hashstring=off \ -h classic,5000009 \ -p thread_pool_max=1000 \ -p lru_interval=60 \ -p esi_syntax=0x00000003 \ -p sess_timeout=10 \ -p thread_pools=1 \ -p thread_pool_min=100 \ -p shm_workspace=32768 \ -p thread_pool_add_delay=1 and the VCL looks like this: # nginx/passenger server, HTTP:81 backend default { .host = "127.0.0.1"; .port = "81"; } sub vcl_recv { # Don't cache the /useradmin or /admin path if (req.url ~ "^/(useradmin|admin|session|sessions|login|members|logout|forgot_password)") { pipe; } # If cache is 'regenerating' then allow for old cache to be served set req.grace = 2m; # Forward to cache lookup lookup; } # This should be obvious sub vcl_hit { deliver; } sub vcl_fetch { # See link #16, allow for old cache serving set obj.grace = 2m; if (req.url ~ "\.(png|gif|jpg|swf|css|js)$") { deliver; } remove obj.http.Set-Cookie; remove obj.http.Etag; set obj.http.Cache-Control = "no-cache"; set obj.ttl = 7d; deliver; } Any suggestions would be greatly appreciated, this is driving me absolutely crazy, especially because its such an inconsistent behaviour.

Adobe Reader XI doesn't allow the editing of fields in a document after it's been edited?

- by leeand00

One of the users at our company has a *.pdf file she received from the state of Pennsylvania. The version of Adobe Reader she is using is Adobe Reader XI 11.0.3. She uses this pdf file to send in a report. Her workflow goes like this: She makes a copy of the file. She opens the file and the file displays in purple at the top: Please fill out the following form. You can save data typed into this form. Highlight Existing Fields She fills in the specifics by entering values into the form fields. A few weeks later she returns to the same pdf document and can no longer edit the fields, instead she gets the following message: "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document." She's also running Windows 7 and I've been told that the issue was once fixed by setting compatibility mode on Adobe Reader XI to Windows XP SP3.

Windows 7 Update freezes - what to do?

- by Tom Tom

Hi, Yesterday I shutdown my notebook, and Windows 7 Ultimate started to install automatic updates. After one hour, I noticed that the update was still running. I thought OK, I shall go to sleep and let it run. In the morning it was still running. Thus, I thought it had crashed, forced a shutdown of the notebook and then restarted it. With the same effect that the notebook is "freezing" at "Install Update 1 of 5". It does not look like it has crashed. The progress wheel is still moving. But it does not make any progress... Would appreciate any help! Edit: OK, I was able to log-in into safe mode. This way I passed the install update screen. I do not want to generally disable updates, what can I do to not install the last update, which is creating troube. Or how can I find out whats the problem with the last update?

Adding file to /etc/cron.d doesn't make it run (ubuntu 10.04)

- by tom

If I scp a cron file into /etc/cron.d it doesn't run unless I edit the file and change the command. Then crond seems to pick up the cron file. How can I make cron reload its cron files in ubuntu 10.04? 'touch'ing the file doesn't work nor does 'restart cron' or 'reload cron'. My cron file is set to run every minute and logs to a file. Nothing ends up in the log file until I edit the command, and there's no entry for it in /var/log/syslog I'm stumped. Here's my cron file saved to /etc/cron.d/runscript # Runs the script every minute. This is safe because it will exit with success if it's already running * * * * * www-data if [ -f /usr/local/bin/thing ]; then exec /usr/bin/php /usr/local/bin/thing mode:prod -a 14 -d >> /var/log/thing/mything.log 2>&1; else echo `date +'[%D %T]'` "Thing not deployed.

Sparc Solaris 2.6 will not boot

- by joshxdr

I have a very old Sparc Solaris network that was working fine last week, but after a power outage none of the workstations will boot. The network looks like this: host A: solaris 2.6, shares /export/home to network by NFS host B: solaris 8, runs NIS server. Mounts /export/home/ by NFS. host C: RHEL5, shares /share to network by NFS. Mounts /export/home/ by NFS. I figured that the main problem was host A, since you need the home directories available for the other workstations to boot(?). Host A does not mount anything by NFS as far as I know. However, this workstation will NOT boot. The OBP bootup sequence looks like this: Boot device <blah> configuring network interface le0 Hostname <hostname> check file system <everything ok> check ufs filesystem <everything ok> NIS domainname is <name> starting router discovery starting rpc services: rpcbind keyserv ypbind done setting default interface for multicast: add net 224.0.0.0: gateway <hostname> <HANGS at this point> Is there some kind of debug mode so that I can get more detail as to why the workstation won't boot? Is my network structure inherently susceptible to power outage? Is there a way I can boot up to command line so I can at least turn off the NFS mounting?

centos install / partitioning

- by ServerSideX

I'm using NOC-PS to remotely install Centos 6.2 via KVM / IPMI. I'm going to install cPanel as well and they recommend this layout /boot (99MB) swap (2x server RAM) / (remainder) In the o/s install profile within NOC-PS software, it shows as this: part /boot --fstype ext2 --size 250 part pv.01 --size 1 --grow volgroup vg pv.01 logvol / --vgname=vg --size=1 --grow --fstype ext4 --fsoptions=discard,noatime --name=root logvol /tmp --vgname=vg --size=1024 --fstype ext4 --fsoptions=discard,noatime --name=tmp logvol swap --vgname=vg --recommended --name=swap By the time the default partition setup was done installing Centos, I get this [root@server005 ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg-root 532G 907M 504G 1% / tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/sda1 243M 28M 202M 13% /boot /dev/mapper/vg-tmp 1008M 34M 924M 4% /tmp [root@server005 ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Fri Dec 7 18:47:24 2012 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/vg-root / ext4 discard,noatime 1 1 UUID=58b31aaf-5072-4fb1-a858-33bc316fa793 /boot ext2 defaults 1 2 /dev/mapper/vg-tmp /tmp ext4 discard,noatime 1 2 /dev/mapper/vg-swap swap swap defaults 0 0 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 My question is, how should the NOC-PS install profile look like to get the recommended cPanel partitioning?

Help trying to figure out why IIS7 is crashing / locking up / denying connections

- by Pure.Krome

Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

Utility to grant admin rights to a user in Windows XP for few hours/days?

- by user15660

I have two accounts on my windows xp home desktop. The default regular user is used for everything and the 2nd user which has admin rights is used only for installations. I do this to avoid malware infestations during web browsing and limited user account is guarding against online threats to a good extend but many programs refuse to run under limited rights like revo uninstaller. many installs i run from limited user by selectin "run as" from right click context menu of the .exe file. but some apps need admin rights for certain. I use "switch user" to go to admin mode and do the install/uninstall. but the admin user has none of my preferences bookmarks setup nor has my locate32 indexing done and ready for fast search Is there a utility which I can use "run as" login in administration login and use that to grant my limited user admin rights for a limited amount of period like few hours or days? Please help. I guess MS might have closed many doors of it for fear of exploitation of the API. are there any?

Wireless keeps shutting off in Windows 7

- by Nathan Adams

I have Windows 7 Ultimate 32bit installed on a Dell Latitude XT Tablet and for the life of me I can't figure out this really weird problem. The symptom is that the Wireless will disconnect from the AP and if I tell it to scan again, it says there are no APs in the area. I do have another wireless card in the laptop and if I disable the first one and enable the second, I am able to get onto the wireless however if I want to use the first card again I have to restart. I tried enabling/disabling the device, nothing will kick start the wireless again in the first card without a restart. I even tried different drivers. So, it seems it is random but it does occur more often when there is increased network activity (ie downloading a large file). The laptop doesn't seem to be overheating. I have tried the following: Under "Change Advanced Power Settings" for the current power profile, I set the "Wireless Adapter settings" to "Maximum Performance". Under device manger, I went to the card in question, and went to the advanced tab and set the "Power Saving mode" to "MAX_PSP" Both cards I have seem to exhibit the behavior after awhile. Both models of those cards are: Dell Wireless 1505 Draft 802.11n WLAN Mini-Card Gigabyte GN-WS30N 802.11n mini WLAN Card Has anyone have any ideas or ran into this before?

Dual hard drive Windows 7 system, modified the registry to get programs to install on second drive, now IE doesn't work

- by paul

I have a dual hard drive Windows 7 system, Windows is installed on an SSD (C:) and I modified the registry to try to force programs to install on second HDD drive (another letter). The registry edits are pretty simple, just a few keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion to change the drive letter. For the most part the system is very fast and works great, but IE doesn't work anymore. With IE10, it opens for a flash with a white window then closes. I tried installed IE11 which opens a white window for a few seconds, doesn't respond, then crashes. I've tried all the solutions I could find. This includes resetting the IE settings, "uninstalling" and re-installing IE, which is just turning it on and off in "Turn Windows Features on or off", copying the Program Files\Internet Explorer files onto both/either drives, changing the registry keys back to use C:, lots of rebooting, and safe mode. Nothing has worked. I don't see errors in the event viewer, but I might not know what to look for. Any ideas on how to get IE running? I don't need IE for daily browsing, I just need it for cross-browser testing on sites I build and on the rare occasion a page only works in IE. I don't really want to use a virtual machine, but would be ok with something standalone like tredosoft's, but I'm not aware of something like that for current versions of IE.

Problem mirroring two monitors with different resolution

- by quad

Hello I am trying to put two monitors in mirror mode (Windows 7 Professional) with Ultramon 3.1.0. The two monitors: Main monitor: 24" Asus. 1680x1050 resolution (16/10). Secondary monitor: 19" LG. 1280x1024 resolution. The graphic card is a Nvidia GeForce 8600 GT. I have installed the Ultramon 3.1.0 and I have created a mirror, with the "stretch mirror image to fill monitor" and the "disable video overlays and 3D acceleration". When I start the mirroring, there are two zones in the lateral edges that are not displayed in the second monitor. I think this is because the width of the main monitor is 1680 px. and the width of the secondary monitor is 1280 px., but I have indicated "stretch mirror image to fill monitor" in the options. The same occurs in the top and the bottom edges, but the diference is minimal (1050 vs 1024 pixels). I want the same image (distortioned in the secondary monitor if is neccesary), but I don't know what is failing. Someone can help me, please? I have read Mirrored monitors of different resolution.

USB seems to pause system

- by Marco van de Voort

I've an application that does some simple measuring, for which it polls a few 100kbs several times a second (8-25 times) The behaviour is not really dependant on chipset (happens on several mobo's intel 965- P55) and OSes (XPsp3 and win7). Also the make of the USB keyboard doesn't seem to matter. I notice that sometimes when an USB kbd is plugged in, the system pauses for say 500-1000ms. (about 900-1000ms on disconnect, and 400-500 on the subsequent connect) It also happens for other USB devices (most notably mice and massstorage devices), but only the first time such device is connected to an installation. This disrupts the measurement and I really would like to get rid on this. I already tried to disable as much as possible. (powersave, teletubby mode (*) etc), and while this helped with the non-USB related disruptions of the measurement, it doesn't help with the USB related ones. (*) fyi, turning off themes (to resp. classic/non-aero), and turning off effects in system solved problems that occured when minimizing/maximizing the app. Any pointers to look into? I'm a bit stuck with this.

Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

- by tednewk

I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

Grayed-Out Sleep and Hibernate Options on Windows 7 After Updating Graphics Driver

- by Maxim Zaslavsky

I have a Gateway M275 Tablet PC, on which I've installed Windows 7 Ultimate. The laptop is quite old, so there aren't any Win7 drivers for it, not to mention any Vista drivers. Win7 has been working for some time, but I noticed that my video output wasn't working. I went into Device Manager and found that I didn't have a driver for my video card: it just recognized it as the standard one. I searched online and found an XP driver for it, released by Gateway. Device Manager accepted this driver and prompted me to reboot. After that, I noticed that my Sleep and Hibernate options in the Shut Down menu have been grayed-out. I looked online and found that many people are attributing this to display drivers, as such an old driver would surely not be compatible with the standby procedures Windows 7 uses. To make it clear: I was able to Sleep and Hibernate before updating the drivers; now, I can't. Running powercfg /a gives me, "An internal system component has disabled this standby state," for each available standby mode. Is there some way that the driver can be modified to support hibernation? The new driver fixed my video output problem, but I guess hibernation is more important for me. If not, what steps should I take to remove the driver and just leave the standard Windows one, which previously supported hibernation and sleep on this computer? Thanks in advance.

System and Router configuration for setting up a home firewall based on Zentyal

- by Ako

I am not much of a system administrator, so please be patient if this looks too simple for you. I have a several computers at home, and all of them connect using an ADSL modem/router (and Wireless AP). I have been attacked several times (mainly from Russia and Ukraine), so I thought I should have some kind of firewall, besides the ESET firewall on my Windows 7. So now I have these (new) configuration: I have a small ADSL modem (Zyxel brand) which has only one Ethernet port. This modem is used to connect to internet and is configured in NAT mode. The interface has is configured with IP address 192.168.1.1. I have an old PC and I have installed zentyal on it. It has two Ethernet ports, eth0 and eth1. Eth0 is connected to the Zyxel modem with IP 192.168.1.2 and is checked as the WAN interface (external). I have another ADSL modem which is also a router with 4 Ethernet ports and Wireless AP. One of the Ethernet ports is connected to eth1 on Zentyal box. The Ethernet port's IP is 192.168.2.1 and Zentyal's eth1 is 192.168.2.2. Now, I want to enable other computers to connect to internet through the router both using Wireless and Ethernet. The problem is that I don't know how to configure the router so it routes connections to the Zentyal box. Does anyone have any clue? Again I am sorry if this looks stupid. Thanks.

nginx logrotate config

- by TomOP

Whats the best way to rotate nginx logfiles? In my opinion, I should create a file "nginx" in /etc/logrotate.d/ and fill it with the following code and do a /etc/init.d/syslog restart after that. This would be my config (I havn't tested it yet): /usr/local/nginx/logs/*.log { #rotate the logfile(s) daily daily # adds extension like YYYYMMDD instead of simply adding a number dateext # If log file is missing, go on to next one without issuing an error msg missingok # Save logfiles for the last 49 days rotate 49 # Old versions of log files are compressed with gzip compress # Postpone compression of the previous log file to the next rotation cycle delaycompress # Do not rotate the log if it is empty notifempty # create mode owner group create 644 nginx nginx #after logfile is rotated and nginx.pid exists, send the USR1 signal postrotate [ ! -f /usr/local/nginx/logs/nginx.pid ] || kill -USR1 `cat /usr/local/nginx/logs/nginx.pid` endscript } I have both the access.log and error.log files in /usr/local/nginx/logs/ and want to rotate both daily. Can anyone please tell me if "dateext" is correct? I want the log filename to be something like "access.log-2010-12-04". One more thing: Can I do the log rotation every day on a specific time (e.g. 11 pm)? If so, how? Thanks.

My SSD stopped working as it ends up in blue death right after windows 7 launches, how can I reset it for new windows install?

- by HattoriHanzo

As I mentioned in the title my SSD suddenly started to fail as after launching Windows 7 it goes straight to completely idle and after a few minutes it goes to blue death and restarts. I have an another HD with a windows xp on it and it works fine and I can also see the SSD and can access everything on it. Windows 7 on the SSD does work in safe mode though yet I didn't manage to find out what causes the problem. Since I can sill access the files and save them to another HD I'm looking for the best way to wipe and reinstall Windows 7. I have yet failed to find an easy to follow (or even understand) guide, different sources on the internet recommend different ways of doing this. And some guides are just simply full of terms I have no clue about. It's an OCZ Vertex 2 120GB. I"d very much appreciate if someone could give me an advice on what I should do, preferably in a way so I could regain the best possible performance as well. it doesn't matter if I don't understand the science behind it as long as I can follow the steps. Thanks!

"Access is Denied" when executing application from Command Prompt

- by xpda

Today when I tried to run an old DOS utility from the XP Command prompt, I got the message "Access is Denied." Then I found that most of the DOS utilities would not run, even though I have "full control" over them. They worked just fine a few weeks ago, and I have not made any OS changes other than Windows Upgrades. Then I tried running edlin.exe and edit.com from the Windows\system32 folder. Same result - "Access is Denied." I tried running these applications from Windows Explorer and got the message "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item." I am logged in as a member of Administrators and have full control over these files. I tried logging in as THE Administrator, with no change. I checked the security settings on the files, and have full control over all of them. I have tried copying the files to different drives, booting in safe mode, and running without antivirus and firewall, all with no change. Does anybody know what could cause this?

Slackware - Assigning routes (IP address ranges) to one of many network adapters

- by Dogbert

I am using a Slackware 13.37 virtual machine within VirtualBox (current). I currently have a number of Ubuntu VMs on a single server, along with this Slackware VM. All VMs have been set up to use "Internal Network" mode, so they are all on a private LAN, and can see each other (ie: share files amongst themselves), but they remain private from the outside world. On on the these VMs (the Slackware one), I need to be able to grant it access to both this private network, and the internet at large. The first suggestion I found for handling this is to add another virtual network adapter to the VM, then set it to NAT. This results in the Slackware VM having the following network adapter setup: -NIC#1: Internal Network -NIC#2: NAT I want to set up the first network adapter (NIC#1) to handle all traffic on the following subnets: 10.10.0.0/255.255.0.0 192.168.1.0/255.255.255.0 And I want the second virtual network adapter (NIC#2) to handle everything else (ie: internet access). May I please have some assistance in setting this up on my Slackware VM? Additionally, I have searched for similar questions on SuperUser and Stackoverflow, but they all seem to pertain to my situation (ie: they all refer to OSX, or Ubuntu via the use of some UI-based tool). I'm trying to do this on Slack specifically via the command-line. Thanks!
