• Transmission-daemon not picking up on watch directory

  - by Mild Fuzz

  Trying to get my transmission-daemon to pick up files from a dropbox folder, to make remote starting easier (it's a headless system). As far as I can tell, the settings.json file is as expected, but none of the files I place in the folder get picked up. I have checked that dropbox is syncing correctly. Here is the whole settings.json file, but the relevant lines are included below: "watch-dir": "/home/john/Dropbox/torrents", "watch-dir-enabled": true Update It appears to be a permissions issue. From /var/log/syslog: Unable to watch "/home/john/Dropbox/torrents": Permission denied (watch.c:79) I have tried stopping the daemon - sudo service transmission-daemon stop - changing permissions of folder using chown - sudo chown -R john /home/john/Dropbox/torrents - restarting daemon - sudo service transmission-daemon start Same result, however Update 2 Permissions for the folder are: drwsrwsrwx 2 john debian-transmission 4096 2012-04-09 19:40

• Enabling NAT forwarding using a second WAN interface and a second gateway on ubuntu

  - by nixnotwin

  I have 3 interfaces: eth0 192.168.0.50/24 eth1 10.0.0.200/24 eth2 225.228.123.211 The default gateway is 192.168.0.1 which I want to keep as it is in the changes I want to make. I want to masquerade eth1 10.0.0.200/24 and enable NAT forwarding to eth2. So I have done this: ip route add 225.228.123.208/29 dev eth2 src 225.228.123.211 table t1 ip route add default via 225.228.123.209 dev eth2 table t1 ip rule add from 225.228.123.211 table t1 ip rule add to 225.228.123.211 table t1 Now I can receive ping replies from any internet host if I did: ping -I eth2 8.8.8.8 To enable NAT forwarding I did this: sudo iptables -A FORWARD -o eth2 -i eth1 -s 10.0.0.0/24 -m conntrack --ctstate NEW -j ACCEPT sudo iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT sudo iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE But it isn't working. To test I used a client pc and put it on 10.0.0.0/24 network and gateway was set as 10.0.0.200. I want to have 192.168.0.1 as default gateway. And the traffic that comes in via eth1 10.0.0.200/24 should be forwarded to eth2 225.228.123.211. I have enabled forwarding on ubuntua also.

• HP Proliant ML115 G5 - Boot order lost after reboot

  - by Filipe YaBa Polido

  I have one HP Proliant ML 115 G5 (AMD) with the latest BIOS (07-06-2009) and recently I've installed an USB disk. This is a common problem on old Proliant servers. When you plug the USB disk, BIOS boot order changes and tries to boot via USB. So, I'll change the BIOS settings and make the SATA disk the default boot device. The problem is, when I need to unplug the usb disk, and plug it again later. I can't be always changing the BIOS settings... How can one solve this for ever?!?!

• How can I find out if a port is opened or not?

  - by Roman

  I have installed Apache server on my Windows 7 computer. I was able to display the default index.php by typing http://localhost/ in the address line of my browser. However, I am still unable to see this page by typing IP address of my computer (neither locally (from the same computer) no globally (from another computer connected to the Internet)). I was told that I need to open port 80. I did it (in a way described here) but it did not solve the problem. First of all I would like to check which ports are opened and which are not. For example I am not sure that my port 80 was closed before I tried to open. I am also not sure that it is opened after I tried to open it. I tried to run a very simple web server written in Python. For that I used port 81 and it worked! And I did not try to open the port 81. So, it was opened by default. So, if 81 is opened by default, why 80 is not? Or it is? ADDITIONAL INFORMATION: 1. In my httpd.conf file I have "Listen 80". 2. This site tells me that port 80 on my computer is opened. 3. I get different responses if I try http://myip:80 and http://myip:81. In the last case browser (Chrome) writes me that link is broken. In the first case I get: Forbidden You don't have permission to access / on this server. 4. IE writes that "The website declined to show this webpage".

• Preventing DDOS/SYN attacks (as far as possible)

  - by Godius

  Recently my CENTOS machine has been under many attacks. I run MRTG and the TCP connections graph shoots up like crazy when an attack is going on. It results in the machine becoming inaccessible. My MRTG graph: mrtg graph This is my current /etc/sysctl.conf config # Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled.

Im no expert, but im not sure if this is ideal. My question is, what are some good things to add to the iptables file and possibly other files which would make it harder for the attackers to attack my machine without closing out any non-attacking users. Thanks in advance!

• Dell Latitude E4300 TouchPad - Odd Behavior

  - by Cade Roux

  I'm seeing some intermittent behavior on the touchpad. First it wasn't working at all. Then during restart, for a little while it seemed like the buttons attached to the joystick and external mouse were both swapped left/right. Then I went in to the dell touchpad control and disabled the touchpad and re-enabled it and nothing happened. Then a short while after disabling the joystick the touch pad started working. So I restarted to see if it would keep the settings and before login, the touchpad appeared to work, then after login it stopped working for a few minutes while login continued. Then after the login was almost completed it started to work again. It appeared to have retained the settings for the disabled joystick. It seems like perhaps there are conflicting mouse drivers trying to simultaneously or similar. This doesn't seem normal for the touchpad to be disabled for so long after login. What steps should I take to ensure the drivers are right?

• Which GPO is making my Domain Controller my clients' DNS server?

  - by Harry Muscle

  I maintain a small domain (about 20 clients) and we need to make some changes to the DNS server that's being used by the clients. All the clients have been hard coded to use the domain controller as their DNS. Since these are new machines, and I never changed their DNS settings, I'm guessing there must be a GPO that's causing them to use the domain controller as their DNS. Since we don't have any GPO other than the default one yet, it's got to be the default GPO, however, I have looked through all the GPO settings and none of them refer to anything related to DNS. So I'm wondering if there's anything else that might be causing this. Any help or advice is highly appreciated. Thanks, Harry

• Why would a FaceBook application "work" on a profile, but not a page?

  - by edt

  I made a FaceBook application that works fine on profiles, but I can't figure out how to get it to show on a FaceBook page. For example, after I visit the application canvas URL, allow the application, then edit application settings and "add" to box and tab view... I cannot click the "plus" symbol to the left of the tabs in order to add a tab for the application. It does not appear in the list of available applications. Meanwhile, the application is working/showing up on profiles with no issues. I DID check the "Installable to Pages" checkbox on the application (authentication tab) settings. What could cause this? Here is the application canvas URL: http://apps.facebook.com/russian_girls/

• Some notebooks can connect to internet via certain wireless router, some can't

  - by Nathaniel

  I take a class in the building of a business and we sometimes use their internet via Wi-Fi. In the last few weeks, though, some notebooks haven't been able to connect to the internet even though they are connected to the router. It affected first a few of us and then all of us. Last week I tweaked around the network settings on the router (yes, the admin password is the same as the network key) and even moved the internet cable on the router from port 1 to the internet port. None of this really worked so I put things more or less back as I found them and alerted someone that someone who knew more than me had better have a look at the router. So, I don't know if anybody has had a look at it but now 2 of us can again connect to the internet. I had a look at the router settings last week and I really couldn't see what might be creating this issue. What might be the problem?

• Disadvantages of enabling 'Low Fragmentation Heap' LFH on Windows Server 2003?

  - by James Wiseman

  I've been investigating an issue with a production Classic ASP website running on IIS6 which seems indicative of memory fragmentation. One of the suggestions of how to ameliorate this came from Stackoverflow: How can I find why some classic asp pages randomly take a real long time to execute?. It suggested flipping a setting in the site's global.asa file to 'turn on' Low Fragmentation Heap (LFH). The following code (with a registered version of the accompanying DLL) did the trick. Set LFHObj=CreateObject("TURNONLFH.ObjTurnOnLFH") LFHObj.TurnOnLFH() application("TurnOnLFHResult")=CStr(LFHObj.TurnOnLFHResult) (Really the code isn't that important to the question). An author of a linked post reported a seemingly magic resolution to this issue, and, reading around a little more, I discovered that this setting is enabled by default on Windows Server 2008. So, naturally, this left me a little concerned: Why is this setting not enabled by default on 2003, or If it works in 2008 why have Microsoft not issued a patch to enable it by default on 2003? I suspect the answer to the above is the same for both (if there is one). Obviously, we're testing it in a non-production environment, and doing an array of metrics and comparisons to deem if it does help us. But aside from this I'm really just trying to understand if there's any technical reason why we should do this, or if there are any gotchas that we need to be aware of.

• Safari proxy bypass for IPv6

  - by rhi

  I'm a first-time n00b on Mac (but have been doing computers since before PC's). This Mac has 2 VLANs, vlan0 in IPv4, vlan1 in IPv6. Safari can surf via IPv4 squid proxy OK. Safari can surf via IPv6 natively, if I switch off the proxy. How do I set up the Settings - Network - Interface - Advanced - Proxies to "bypass" IPv6? Current Settings include variations along the lines of ... "*.local, 10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12 , ::, ipv6 " but don't work as expected. I want Safari to go out on its own with IPv6, not crash at the proxy with "malformed URL" Thanks, //rhi

• microsoft mouse and keyboard center doesn't show my mouse

  - by Andy

  as part of a recent windows update, the irritating and intrusive intellipoint microsoft mouse software now seems to have been replaced by the even more irritating and intrusive "microsoft mouse and keyboard center[sic]" I am left handed and need to switch the left and right mouse buttons round. the option to do this has disappeared from the mouse control panel, to be replaced by a link which opens up said mouse and keyboard center. this in turn is a window which allows me to change settings on the keyboard but does not have any way to control mouse settings any hints would be very welcome. this is driving me nuts.

• custom adm file for IE search providers on Windows 2003

  - by filipv

  Hi, I have been stumped by this issue for some time, I created a custom ADM template for a customer to populate the search providers in Internet Explorer 7 and 8. The custom ADM works fine and I have set 3 search providers, the problem is that I cannot change them (the customer wants to change the entry for wikipedia from EN to NL), I edited the ADM file but the clients seem to keep on using the old settings. Removing/replacing the adm file has no effect either, the settings remain. I used the following article as a base: http://support.microsoft.com/kb/918238 For IE8 you need to work with a name instead of a UID for the default entry, that works as expected. but there seems to be no way to change the setting once in place.

• Could some one please explain the various proxy configuration scenarios?

  I am working on a client application in C# which does a various kinds of communication with a server( eg: uploads, downloads etc ). We have a legacy system which does the same functionality and we get in to proxy configuration related issues frequently.It uses the settings from internet explorer network settings. Most of the time these are due to specific proxy configuration( Eg: Proxy auto-config etc ). I am trying to understand the various scenarios used in corporate environments for proxy configurations. Could some one please explain the various proxy configuration scenarios?

  I installed the dovecot-imapd package in Ubuntu, and my setup is as follows: $ sudo dovecot -n # 1.2.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-27-generic-pae i686 Ubuntu 10.04.1 LTS log_timestamp: %Y-%m-%d %H:%M:%S protocols: imaps login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:~/Maildir mbox_write_locks: fcntl dotlock auth default: passdb: driver: pam userdb: driver: passwd For security reasons I would like to deny all users that are in the admin group ability to do imap login via dovecot. This is done in order to prevent a brute force attacker from discovering the admin passwords, and obtaining administrator privileges on the system. How can this be achieved? Presumably, I will have to modify some settings in /etc/dovecot/dovecot.conf, but I am hesitant to change the default settings lest I create other security vulnerabilities.

• What kinds of protections against viruses does Linux provide out of the box for the average user?

  - by ChocoDeveloper

  I know others have asked this, but I have other questions related to this. In particular, I'm concerned about the damage that the virus can do the user itself (his files), not the OS in general nor other users of the same machine. This question came to my mind because of that ransomware virus that is encrypting machines all over the world, and then asking the user to send a payment in Bitcoin if he wants to recover his files. I have already received and opened the email that is supposed to contain the virus, so I guess I didn't do that bad because nothing happened. But would I have survived if I opened the attachment and it was aimed at Linux users? I guess not. One of the advantages is that files are not executable by default right after downloading them. Is that just a bad default in Windows and could be fixed with a proper configuration? As a Linux user, I thought my machine was pretty secure by default, and I was even told that I shouldn't bother installing an antivirus. But I have read some people saying that the most important (or only?) difference is that Linux is just less popular, so almost no one writes viruses for it. Is that right? What else can I do to be safe from this kind of ransomware virus? Not automatically executing random files from unknown sources seems to be more than enough, but is it? I can't think of many other things a user can do to protect his own files (not the OS, not other users), because he has full permissions on them.

• Chassis fans and power LEDs still work in Hibernate

  - by Jaded

  I have ASRock Z68 Extreme3 Gen3 motherboard recently updated to 2.20 BIOS version. OS is Windows 7 x64. The problem is after that update full hibernation (by that i mean full system power off) stopped working although everything was fine before. Now when I press hibernate, sleep in initiated as usual, monitor goes to sleep, HDD and CPU fan stop spinning, but chassis fans (i have Gigabyte Aurora 3D 570 case with two rear and one front fans) still remain working. Also power leds are lit as if computer is turned on. Tried changing different UEFI settings related to sleep mode, and none of them change above described behaviour. I have "Deep Sleep" (Advanced-South Bridge Configuration) set to "Enabled in S4-S5", "Suspend to RAM" (Advanced-ACPI Configuration) set to "Auto", all fans settings in "H/W Monitor" set to "Auto".

• A "region code" restriction for a custom created video dvd file

  - by user180820

  I want to create a video dvd ( no menus, just "plug and play" ) from a few video files. I`m doing it like this: ffmpeg -i sample-media/hellboy-2.wmv -y -target ntsc-dvd sample-media-to-mpeg/hellboy-2.vob dvdauthor -o sample-dvd -x dvdauthor-settings.xml mkisofs -dvd-video -o hellboy-2-trailers.iso sample-dvd/ where "dvdauthor-settings.xml" is: link. But when I try to play the iso file in windows it says: Windows Media Player cannot play the DVD because the disc prohibits playback in your region of the world. You must obtain a disc that is intended for your geographic region. When I open the *.IFO file with IfoEdit it says that all world regions are unabled. Can someone tell me why is this happening? ( maybe the whole process of creating the *.iso file is wrong? )

• Scheduled task username changed

  - by Ernst

  I posted this originally on stack overflow where I was told I should ask it here: Hi, I created a user on our exchange server, but later changed the username. Now, when I create a scheduled task for that user, and change it's settings (run only when logged on), the username is automatically changed back to the old username. What's causing this and how do I make sure the correct, new username is used for the task (otherwise it won't run), security settings are okay. I did already log in with a different user to delete the profile on the computer and tried again with this user to no avail. The OS is windows xp, the exchange server is on windows server 2003. Thanks

• Google Chrome issues

  - by Ben Hooper

  I'm an avid user of Chrome and would defend it to the death but there is no denying that it has issues, and I've been experiencing a lot of them recently. Issues Stuck tabs Issue: Around 60% of the time (higher when the system has just started), when Chrome is launched, some or all of the pinned tabs and startup pages will get stuck in the counter-clockwise-rotating "contacting server" mode and never snap out of it. Fix: Quit and launch Chrome until they load properly (this really isn't good, as quitting and launching Chrome can and has cleared all pinned tabs). Extra Information: If you stop the loading and re-enter the URL then the page will load perfectly. The amount of pinned tabs or startup pages seems to be irrelevant, but I could be wrong.   "Downloaded/out of" Issue: Each item in the download bar has a downloaded status section, formatted as "downloaded/out of". Sometimes Chrome doesn't display the "out of" part.   Collapsed settings windows Issue: In Chrome version 19(ish)+, settings are configured via overlayed / popup windows. Sometimes, the window will open fully collapsed. Fix: Resize Chrome's window or open the developer tools. "Network Error" with large downloads Issue: Sometimes, when downloading large files (500MB+) Chrome will download the entire file, the download status will freeze (for example, "1 GB/1 GB") for a few minutes, report "Network error", and delete the .crdownload file. Extra Information: The same file from the same website on the same computer downloads perfectly in other browsers. The website and file type seem to be irrelevant.   Information: I've experienced some of these issues on my home PC and some on my work PC, both of which are Windows 7 Ultimate x64. The only things that link them are my Google account (all settings are synced). Updating Chrome hasn't worked. Most of these issues presented themselves around about version 17 and have continued right through to 21 (current). Uninstalling Chrome, deleting all data in %programFiles(x86)%\Google and %localAppData%\Google, and reinstalling hasn't worked. I have yet to see whether disabling all extensions would make a difference, but it's hard to diagnose as these issues don't occur 100% of the time.   In my case, I don't know if there's an actual solution. I'm just curious as to whether anyone else is having similar issues to those that I'm experiencing. At least then I'll know it's an issue with Chrome itself.
