  • Chrome drag and drop download links

    - by Brad
    In Chrome, I used to be able to take a link to a file and just drag to a folder on my system. Chrome would then download whatever resource was at the URL for the link and put it into the folder dropped into. This was particularly handy when using Gmail. If there was an attachment, I could just click and drag it into a folder, and Chrome would download it for me to the correct place. Now I have to hit download, and then drag from the download bar when it is finished. Has this feature been removed? Is there any way to bring it back?

  • Block users from Social networking websites while firewall is down

    - by SuperFurryToad
    We currently have a SonicWall firewall, which does a pretty good job a blocking Social networking websites like Facebook and Bebo. The problem we are having is that sometimes we need to temporarily disable our firewall blocklist so we can update our company's page on Facebook for example. Whenever we do this, have see an avalanche of users logging on to their Facebook pages during work time. So what we need a way to block access while the firewall is down. For the sake of argument, we have two groups of users - "management" and "standard users". "standard users" would have no access to Facebook, but "management" users would have access. Perhaps something like a host file redirect for non-management users. This could probably be enforced via group policy that would call a bat file to copy down the host file, depending if the user was management or not. I'm keen to hear any suggestions for what the best practice would be for this in a Windows/AD environment. Yes, I know what we're doing here is trying to solve a HR problem using IT. But this is the way management wants it and we have a lot of semi-autonomous branch offices that we don't have a lot of day to day contact with, so an automated way of enforcing this would be the most preferable method.

  • Remote paging with Nagios when network is down and email won't work -- cellular modems and alternatives

    - by Quinten
    What is the best option for remote paging when network services are down? I'm looking for a solution that can let me know when network services are down during off-hours only, and especially when email/smtp services are out. Therefore, it needs to be redundant to our network and power supply. I'm imagining a cellular modem is one option. What's the price range for these? Is anybody using them and feel that they are worth the cost? I'm imagining that it's something we would end up sending an emergency page ~ 1x/month at most, so I'd like the pricing to reflect that--I don't mind a high per-page cost as long as it has a low recurring cost. Another option would be to expose at least one server to remote ping, and run a check script on a remote server. Are there paid options for this? Currently, we run Nagios on a Linux VM on a Windows 2008 Hyper-V host. It would be great if the solution would work in that environment, but I know it's tricky with external devices, and we could move Nagios to a standalone workstation if needed.

  • Large file copy from NFS to local disk performance drop

    - by Bernhard
    I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler). I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit. At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes. Any ideas what could be causing this?

  • Help, my CentOS servers keep going down , No route to host after a random uptime

    - by user249071
    Hello , I have a couple of Centos linux servers, that have a very simple task, they run nginx + fastcgi for php , and some NFS mounts between them, readonly They have some RPC commands to start some downloading processes with wget, nothing fancy , from a main server, but their behavior is very unstable, they simply go down, we tried to monitor ram , processor usage, even network connections, they don't load up so much, max network connections up to... 250 max, 15% processor usage and memory , well, doesn't even fill up, 2.5GB from 8GB max , I have no ideea why can a linux server go down like that, they aren't even public servers, no domain names installed no public serving, for sites. The only thing that I've discovered was that if i didn't restart the network service every couple of hours or so... the servers were becoming very slow, starting apps very slow, but not repoting a high usage of resources...Maybe Centos doesn't free the timeout connections, or something like that...It's based on Red Hat right? I'm not a linux expert , but I'm sure that there are a few guys out there that can easily have an answer to this , or even have some leads to what i can do ... I haven't installed snort, or other things to view if we have some DOS attacks, still the scheduled script that restarts the network each hour should put the system back online, and it doesn't.... Thank you in advance

  • About Eclipse's "Upgrade" menu in Team

    - by djechelon
    I wonder what that command means. I have a project shared on Subversion and this strange menu item appeared to me. I tried to click it, but Eclipse required me a confirmation to proceed because the operation cannot be undone. Eclipse version Eclipse IDE for Java Developers Version: Indigo Service Release 2 Build id: 20120216-1857 I didn't post on SO because my question is related to Eclipse itself and not to programming

  • Nagios send mail when server is down

    - by tzulberti
    I am using nagios 3.06 to monitor the servers. When a service is critical, it sends a mail, but when a server is down no mail is sent. Even if all the services go to critical state, no mail is sent. I have the following configuration: define command {     command_name notify-host-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$" "******** Nagios ****\n\n Host: $HOSTNAME$\n Description: the server is down" } define command{     command_name notify-service-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$: $SERVICEDESC$ ($NOTIFICATIONTYPE$)" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nDate/Time: $LONGDATETIME$\nAdditional Info:$SERVICEOUTPUT$" } The python script is a script to sent a mail. It works if I execute it from the command line, but it doesn't sents an email from nagios. What I am doing wrong? UPDATE: The contact data is: define contact{     contact_name root     alias Root     service_notification_period 24x7     host_notification_period 24x7     service_notification_options w,u,c,r     host_notification_options d,r     service_notification_commands notify-service-by-email     host_notification_commands notify-host-by-email     email [email protected] } define contactgroup{     contactgroup_name admins     alias Nagios Administrators     members root }

  • HP tx2510us shuts down without warning, now won't boot, no BIOS codes, screen doesn't light

    - by Tim S
    Hey all, HP tx2150us worked great for a year and a half, rarely it would shut down instead of sleeping. It started running hot sometimes, I installed Win7, worked great, still running hot. Before Xmas, it gave me evidence of video errors - jagged lines, rows missing. That same night, it started rebooting, then it shut off and wouldn't boot. It gave me a BIOS code, I shut it off to look up the code online. When I turned it on again, it won't boot at all. The LEDs all light up, the fan, HD, and optical all spin up, but the screen never lights up and it doesn't try to boot, nor does it blink any BIOS codes. It just acts like it's sleeping, and won't wake up. I suspected heat problems, so I disassembled it, cleaned the crap out of the fan, and reassembled it, breaking the stereo mic connector. Oh well. When I reassembled it, it booted up into Win7 again, but kept shutting down for no discernible reason. After a dozen or so random reboots like that, it is now back to where it was - turns on but doesn't boot or give BIOS codes. The screen never lights, and everything spins up then idles. Any ideas? I really can't afford to buy a new one and I use(d) it to take ALL my notes, that's why I got a tablet in the first place.

  • OS X won't boot up unless I hold down option key

    - by Gazzer
    I have a strange issue on an early 2008 Mac Pro running OS 10.6: if I restart the computer it restarts normally if I shutdown and boot, it stops at the grey screen just before the boot process if I shutdown and boot but hold down the option key, I can select the boot disk and all is good. I've just cloned the disk, and the same thing happens. The disk is a SAMSUNG HD154UI The disk is partitioned (the second partition holds a clone of the Snow Leopard Install disk) One weird thing on the original disk was one of the partitions said 'EFI Boot' in a non-aliased font rather than the name of the disk when the disks are listed upon holding down option. Solution: it seems that there was a problem with the disk. Part of the difficulty in finding the solution was that you need to remove the disk from the computer completely. For example, a good disk in Bay 3, wouldn't boot up if the bad disk was in Bay 2. So for ages I thought the problem was hardware related in Bay 3. So if you think you have a dodgy disk remove it totally if you are testing the hardware with a 'clean' disk. Cleaning the PRAM helped to get the new disk to work too.

  • Servers/Websites Keep Going Down

    - by Tyler Johnson
    Okay, I'm a noobie. I know how to build and compose a website, but I have no idea what I'm doing when it comes to servers and server commands, etc. I've recently had a problem with all of my sites on our servers going down all at once and then I have to go in and reboot the server for them to come up again. At first this was annoying, but now it is becoming agonizing as it now takes 3-4 reboots for the websites to come back up. I contacted support for my hosting, but they are not being very helpful. They just keep telling me what the issue might be and basically telling me that I'm going to have to look into it and figure it out, which really isn't possible since I know nothing. Anyway, here are the things they said were possible reasons: They said I have "strange logs" in my Apache webserver log, error: sh: fetch: command not found. My php.ini memory limit is: 256M which is very high. It should be 32M or 64M. Server is reaching Max Clients, meaning we have more than 150 visitors at a time. (They supposedly "fixed" this, but the sites/server are still going down) I have some Wordpress sites with plugins getting errors like: PHP Warning: pack(): Type H: illegal hex digit G in... PHP Fatal error: Cannot use object of type stdClass as array in... PHP Fatal error: Maximum execution time of 30 seconds exceeded in... PHP Fatal error: Call to undefined function file_exists() in... PHP Parse error: syntax error, unexpected '<' I know that's a lot, but I really am at wits end and have no idea what to do now. If anyone could maybe give me some advice or point me in the right direction I would greatly appreciate it! Thanks! Oh, and here are the specs for my server: RAM: 2048MB CPU Shares: 40 Primary Disk: 50GB Data Transfer: 75GB Port Speed: 5Mbps Type: Linux

  • Information on 50% drop in spam starting Christmas 2010

    - by George Bailey
    Has anybody who administers email servers or spam filtering noticed that in last couple of weeks the spam volume has dropped significantly? Is there a chart provided by one of the major spam filtering companies? Edit: Based on our internal stats, although it varies, on the two weeks starting the day after Christmas (Sunday), spam seems to be coming in about half as much as it did before Christmas.

  • Problems with Net::FTP slowing down

    - by c0bra
    I'm running into an issue with using Net::FTP (latest version 2.77) to transfer files to a remote host where a process is waiting to take the file and feed into some other system. The remote process does this every 5 minutes but ignores files that were modified in the last 0.2 seconds (that's right, 1/5th of a second). The problem is that for some reason the transfer seems to halt or slow down a bit and no data is transferred for several seconds and during this time the process picks up the incomplete file and removes it. The weird thing is that manually using the ftp binary the file seems to transfer fine. I've tried messing with all of the Net::FTP switches (Active/Passive, different Blocksizes) and nothing seems to help. What's also weird is that the file seems to transfer fairly quickly at first and on occasion a bit into the transfer. Like 300-500k will go up immediately, but then it slows down to where the file size is only increasing by 2,896 bytes every several seconds. It doesn't seem to happen when I try sending the file to a different remote host, but since a regular manual ftp transfer works with this host I don't know what to think. Some combination of Net::FTP and possibly a slow or wonky connection?

  • Combat server downtime by duplicating server and re-routing when main server is down

    - by Wasim
    I have a CentOS server which at times either crashes or gets attacked with DDOS. At the moment I have an off site backup which is filled up with 1.7TB of data. I'm currently paying as much for the backup as I am for the server and I was looking for advice from experienced people as to what option is best to proceed from here. Would it be a viable solution to ditch the offsite backup, and instead purchase an additional server which is an exact duplication of the first server. So if the first server is down, users are re-routed to the second server without noticing the first server is even down. This would create an automatic backup of the first server (albeit not offsite) and relinquish the need for the expensive offsite backup. Is the above solution a true solution to pricey backup or is offsite backup absolutely necessary? How would I go about doing this (obviously it's pretty complex so just links to some reading material or the terminology of the procedure would be great)? Appreciate the help and advice.
