• Running Safari from the command line adds current directory to the URL

  - by Charles Anderson

  I am trying to run the Safari browser (on Mac OS 10.4) from the command line, as follows: /Applications/Safari.app/Contents/MacOS/Safari http://localhost/dev/myfile.html However, Safari starts up and tries to access file:///Users/charlesanderson/scripts/http://localhost/dev/myfile.html /Users/charlesanderson/scripts happens to be my current directory. Can someone explain why Safari does this? Firefox is much better behaved?

• Windows' MSN Zone internet games will not launch due to error

  - by zechdc

  I keep getting this error when trying to launch Internet Spades on a Windows XP machine: Spades is unable to start. Close some other programs and try again, or try reinstalling Spades using Add/Remove Programs in Control Panel. I used the Add/Remove programs to disable, then enable games. It asked for the Windows XP CD which I put in. Did some stuff like it was working. Still get the same error message.

• Cisco VPN stops Windows 7 Browsing

  - by Sharjeel Sayed

  My browsing and other 'internet' activity (dropbox,digsby etc) halts when I connect to my office VPN using Cisco Systems VPN client Version 5.0.04.0300 on my Windows 7 Ultimate.The only option left for me at this time is to use my office proxy to enable the connection back. I tried doing the ucheck "Use default gateway on remote network" solution as mentioned on a previous post Windows 7 VPN stops web browser but I don't see that option on the properties of "Cisco systems VPN adapter" connection properties. Here is the screenshot

• Optical multicast

  - by Randomblue

  I have a 10G XPF+ optical cable with market updates from a stock exchange. This cable goes into a switch, which then multicasts every packet to a couple of computers. The problem with using a switch for multicast is that there is latency overhead, even with a pass-through switch (~200ns). Are there "optical" solutions (I'm thinking of a beam splitter of some sort) which would allow for close to zero latency 10G multicast?

• How to direct reverse proxy requests using wildcard vhosts

  - by HonoredMule

  I'm interested in running a reverse proxy with 2-3 virtual machines behind it. Each internal server will run multiple virtual hosts, and rather than manually configuring each individual vhost on the proxy (a variety of vhosts come and go too often for this to be practical), I would like to use something which can employ pattern matching in a sequential order to find the appropriate back-end server. For example: Server 1: *.dev.mysite.com Server 2: *.stage.mysite.com Server 3: *.mysite.com, dev.mysite.com, stage.mysite.com, mysite.com Server 4: * In the above configuration, task.dev.mysite.com would go to Server 1, dev.mysite.com would go to Server 3, yoursite.stage.mysite.com to Server 2, www.mysite.com to Server 3, and yoursite.com to Server 4. I've looked into using Squid, Varnish, and nginx so far. I have my opinions regarding their respective desirability and general suitability, but it's not readily apparent if any of them can handle dynamic server selection in this manner and not require per-vhost configuration. Apache on the other hand can do this handily and simply, but otherwise (aside from being well-known and familiar) seems very poorly suited to the partly-performance-serving task. Performance isn't actually a major concern yet, but it seems foolish to use Apache if another system will perform far better and can also handle the desired 'hands-free' configuration. But so is frequently having to adjust the gateway for all production services and risk network-wide outage...and so also is setting oneself up for longer downtime later if Apache becomes a too-small bottleneck. Which of these (or other) reverse proxies can do it/would do it best? And maybe I should post this as a separate question, but if Apache is the only practical option, how safe/reliable/predictable is apache-mpm-event in apache2.2 (Ubuntu 12.04.1) particularly for a dedicated reverse proxy? As I understand it the Event MPM was declared "safe" as of 2.4 but it's unclear whether reaching stability in 2.4 has any implications for the older (2.2) versions available in official/stable package channels of various distros.

• Unix style command line history in windows

  - by dean20007

  This may be a duplicate so feel free to close and point me in the right direction but is there a way of getting Unix style command line recall in windows. E.g. Opening a new command window and using the up arrow key will recall the last x number of statements. I know this works in the command window per command window session but is there a way to persist across sessions?

• Forward all traffic through an ssh tunnel

  - by Eamorr

  I hope someone can follow this and I'll explain as best I can. I'm trying to forward all traffic from port 6999 on x.x.x.224, through an ssh tunnel, and onto port 7000 on x.x.x.218. Here is some ASCII art: |browser|-----|Squid on x.x.x.224|------|ssh tunnel|------<satellite link>-----|Squid on x.x.x.218|-----|www| 3128 6999 7000 80 When I remove the ssh tunnel, everything works fine. The idea is to turn off encryption on the ssh tunnel (to save bandwidth) and turn on maximum compression (to save more bandwidth). This is because it's a satellite link. Here's the ssh tunnel I've been using: ssh -C -f -C -o CompressionLevel=9 -o Cipher=none [email protected] -L 7000:172.16.1.224:6999 -N The trouble is, I don't know how to get data from Squid on x.x.x.224 into the ssh tunnel? Am I going about this the wrong way? Should I create an ssh tunnel on x.x.x.218? I use iptables to stop squid on x.x.x.224 from reading port 80, but to feed from port 6999 instead (i.e. via the ssh tunnel). Do I need another iptables rule? Any comments greatly appreciated. Many thanks in advance, Regarding Eduardo Ivanec's question, here is a netstat -i any port 7000 -nn dump from x.x.x.218: 14:42:15.386462 IP 172.16.1.224.40006 > 172.16.1.218.7000: Flags [S], seq 2804513708, win 14600, options [mss 1460,sackOK,TS val 86702647 ecr 0,nop,wscale 4], length 0 14:42:15.386690 IP 172.16.1.218.7000 > 172.16.1.224.40006: Flags [R.], seq 0, ack 2804513709, win 0, length 0 Update 2: When I run the second command, I get the following error in my browser: ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://109.123.109.205/index.php Zero Sized Reply Squid did not receive any data for this request.

• Dual monitors and flash movie to stay maximized on one of them.

  - by Kamil Zadora

  I have recently assembled a dual monitor setup. I often watch live.twit.tv in my browser and I would like to run it maximized while I do other stuff on second screen, but when I click on a desktop the full screen mode rolls back to normal view. The same case is for different Flash players and I believe Silverlight players suffer from the same problem. Is there any way to bypass this behavior?

• There are lots of "Core i" CPUs, but Dell only offers a few -- who builds systems with the others?

  - by Jesse

  Passmark shows many varieties of Core i3, i5, and i7 cpus. Some of them, even at similar prices, are much faster than others. But Dell only offers a few options, and they're not the fast ones. For example, Dell offers the Core i5 650 (benchmark), which costs $220, and doesn't come close to the performance of the Core i3-2100 (benchmark), which costs $120. Does anyone sell systems with the faster, cheaper chips?

• DNS queries to compromise DNS cache [on hold]

  - by Chris

  The transaction ID for DNS queries can take values from 1 to 65,536 and my computer pseudorandomly chooses one for each DNS request. If I sents 1,024 false replies per request, how many requests should I trigger to compromise the DNS cache with probability 99%? or as close tot hat as I can get. Thanks I'm getting a result of .6 requests which doesn't seem right to me. Feel as though it should be around 30

• Disabling the Squid Error pages

  - by Nicholas Smith

  I've just started looking at using Squid for a project and can't seem to see an easy way of disabling the Squid error pages (e.g. "Name Error: The domain name does not exist"). We use a custom browser which handles that scenario in our way, so the Squid error pages are overriding our custom logic. Is it possible to set them too 'off'? I've been through the .conf and I've found where the error pages are stored, but no real options to disable them.

• Uninstall php and nginx or fix setup

  - by jreed121

  First off, I'm a huge linux noob - sorry... I'm trying to setup nginx with php-fpm on debian and I'm pretty sure that I've completely screwed it up. nginx seems to be running fine because I can it it from a web browser and it load the stock "Welcome to nginx!" page. I'm not so sure about php-fpm though. When I try something like # restart php-fpm I get: bash: restart: command not found First off php-fpm some how got installed as php5-fpm when I do root@server:/etc/init.d# ls, which seems to contradict every tutorial and help doc I've read (supposed to be 'php-fpm'). I can restart it with this: service php5-fpm restart And just enter the package name 'php5-fpm' I get this: root@server:~# php5-fpm [17-Nov-2012 23:15:36] NOTICE: PHP message: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20100525/suhosin.so' - /usr/lib/php5/20100525/suhosin.so: cannot open shared object file: No such file or directory in Unknown on line 0 [17-Nov-2012 23:15:36] ERROR: An another FPM instance seems to already listen on /var/run/php5-fpm.sock [17-Nov-2012 23:15:36] ERROR: FPM initialization failed The root for nginx is /usr/share/nginx/html, when I try to navigate to a .php file in there with my web browser, it tries to download the file instead of interpret it. I would like this folder to be in my user's home directory ie: /home/administrator/www or /home/nginx/www. I know in order to do this I need to modify nginx.conf, but I find that configuration file difficult to understand. I suppose the fact that my .php scripts aren't being handled is my bigger problem anyways. When I try to see what running on port 9000 (php-fpm default port) with lsof -i :9000 it returns nothing - I guess indicating that it isn't listening. then I head over to vim /etc/php5/fpm/php-fpm.conf and there is no where to designate a port number. So should I just uninstall everything and start from scratch? If so, how do I clean it all up? Any suggestions for a tutorial once I'm ready to try again? Should I attempt to troubleshoot this mess? If so where should I start? Sorry guys, I'm feeling pretty stupid and lost right now. I'm not sure what my next steps are in trying to resolve this issue are. I realize that this is a horrible question for this type of Q&A site, but I'd really appreciate any guidance.

• Excel shortcut: switching back and forth between that last active sheet and the current exit sheet

  - by thomasssssss

  I know the shortcut CRTL + page up/down but I need the similar function that exists eg in internet explorer: Shift + alt I found a macro that is close but does not entirely solve the problem: If ActiveSheet.Name = "To Do" Then Sheets("Budget").Activate ElseIf ActiveSheet.Name = "Budget" Then Sheets("To Do").Activate I can name the A1 cell with the sheet name and use search (f5) and type the name, but this is to cumbersome. Any ideas, guys?

What is a ATAPI Error? Do I need to re-install Windows? I generally find the occurs when I try to backup my machine (using Windows Backup) or when using a program that uses Volume Shadow Copy. I have run "sfc", no problems. There are no Device Errors in Device Manager. I have also run "vssadmin list writers", no problems. Whats going on??? Would it be a good idea to re-install Windows 7?

• 0 connected nodes in datastax opscenter

  Installed opscenterd on the separate node outside of the cluster, but within firewall ( aws security group ). Tested all possible ports between agents and opcenter server. No errors in the log.. 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Initializing event storage. 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Attempting to load all persisted alert rules 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Done loading persisted alert rules 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Done initializing event storage. 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: Done loading persisted scheduled job descriptions 2013-10-30 01:07:23+0000 [FC_Cluster] INFO: OpsCenter starting up. 2013-10-30 01:07:23+0000 [] INFO: Finished starting new cluster services for FC_Cluster 2013-10-30 01:08:04+0000 [FC_Cluster] INFO: Agent for ip 10.34.10.185 is version u'3.2.2' 2013-10-30 01:08:04+0000 [FC_Cluster] INFO: Agent for ip 10.32.37.251 is version u'3.2.2' 2013-10-30 01:08:04+0000 [FC_Cluster] INFO: Agent for ip 10.82.226.252 is version u'3.2.2' The most interesting part that I can see some data in the opscenter UI, when I stop agents, there is no data displayed, when I start - it show up again, but at the same time it shows 0 connected nodes. Storage capacity is even funnier - 3 of 0 nodes.. Any ideas why that could be happening?

• How to copy remote machines text to local machines clipboard through SSH?

  - by recluze

  I work on a remote machine through ssh. I have a very large text file there (approx. 500 lines) which I usually need to modify, then copy the contents of that file and paste it in my local browser. The way I usually do this is cat filename and then select/copy the ssh output. That takes a lot of time. I was wondering if there is a utility that will put the remote file's contents in my local clipboard.

• When did my Mac's HD last sleep?

  - by flipdoubt

  Is there any app or log that says when my MacBook Pro's hard drive last went into sleep mode? I ask because each night when I close the MBP's lid without being plugged into a power source, the power light goes into its snooze rhythm but the battery is half-drained by the next morning. It certainly looks like it is asleep, but the power drain seems to indicate otherwise.

• How do I use Group Policy on a domain to delete Temporary Internet Files?

  - by Muhammad Ali

  I have a domain controller running on Windows 2008 Server R2 and users login to application servers on which Windows 2003 Server SP2 is installed. I have applied a Group Policy to clean temporary internet files on exit i.e to delete all temporary internet files when users close the browser. But the group policy doesn't seem to work as user profile size keeps on increasing and the major space is occupied by temporary internet files therefore increasing the disk usage. How can i enforce automatic deletion of temporary internet files?

• ISA 2006 SP1 - SSL Client Certificate Authentication in Workgroup Environment

  - by JoshODBrown

  We have an IIS6 website that was previously published using an ISA 2006 SP1 standard server publishing rule. In IIS we had required a client certificate be provided before the website could be accessed... this all worked fine and dandy. Now we wish to use a web publishing rule on ISA 2006 SP1 for this same website. However, it seems the client certificate doesn't get processed now, so of course the user can't access the website. I've read a few articles stating the CA for the certificate needs to be installed in the trusted root certificate authorities store on the ISA Server (i have done this), as well as installing the client certificate on the ISA Server (done as well). I have also verified that the ISA Server is able to access the CRL for our CA no problem... In the listener properties for the web publishing rule, under Authentication, and Client Authentication Method, there is an option for SSL Client Certificate Authentication... i select this, but it appears the only Authentication Validation Method selectable is Windows (Active Directory).... there is no Active Directory in this environment. When i configure the rule with the defaults, I then try to hit my website and it prompts for my certificate, i choose it and hit ok... then I'm given the following error Error Code: 500 Internal Server Error. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) I check the event logs on the ISA Server and in Security Logs, i see Event ID 536, Failure Aud. The reason: The NetLogon component is not active. I think this is pretty obvious since there is no active directory available. Is there a way to make this web publishing rule work using client certificates in this workgroup environment? Any suggestions or links to helpful documents would be greatly appreciated!

• "The zone can be scavenged after" keeps incrementing

  - by kce

  What are you trying to do? I'm trying to enable DNS scavenging on a DNS zone that has about a hundred stale DNS records. What have you tried in order to make it happen? I setup DNS Scavenging per everyone's favorite TechNet Blog post: Don't be afraid of DNS Scavenging. Just be patient. I first disabled scavenging on all of our domain controllers: DNSCmd . /ZoneResetScavengeServers contoso.com 192.168.1.1 192.168.1.2 I then enabled automatic scavenging on the DNS zone: I then enabled DNS scavenging on one of the domain controllers: I then found a few records that I expected to get delete with timstamps from a few years ago and ensured that that the Delete this record when it becomes stale and that time stamp was actually set: Finally I reloaded the zone and waited 14 days (the sum of the Refresh + No-Refresh periods). What results did you expect? I expected to see a 2501 Event in the DNS server logs noting the deletion of a bunch of DNS records. What actually happened? Nothing happened. The Zone Aging/Scavenging Properties showed that the zone could be scavenged after 6/12/2014 10:00:00 AM last week. No 2501/2502 events were recorded. All of the records with "aged" time stamps are still present. The date at which the zone can be scavenged after incremented another seven days to ?6/?18/?2014 10:00:00 AM. As I understand it until that date stays at least 14 days in the past nothing will ever even be eligible for scavenging let alone actually be scavenged. The only 2501 events recorded in the event logs are ones that I have triggered by right clicking and selecting "Scavenge Stale Resource Records". They note that scavenging will try to run again in 168 hours which was this morning. I have DNS scavenging enabled for a few months and have waited patiently for something to happen. I have reloaded the zone multiple times (which resets this timestamp). What am I missing here?
