• Avoiding syslog-ng noise from cron jobs [closed]

  - by Eyal Rozenberg

  Possible Duplicate: How can I prevent cron from filling up my syslog? On my small Debian squeeze web server, I have syslog-ng installed. Generally, my logs are nice and quiet, with nice -- MARK -- lines. My syslog, however, is littered with this Sep 23 23:09:01 bookchin /USR/SBIN/CRON[24885]: (root) CMD ( [ -x /usr/lib/php5/maxlifetime ] && [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -delete > /dev/null) Sep 23 23:09:01 bookchin /USR/SBIN/CRON[24886]: (root) CMD ( [ -d /var/lib/php4 ] && find /var/lib/php4/ -type f -cmin +$(/usr/lib/php4/maxlifetime) -print0 | xargs -r -0 rm > /dev/null) Sep 23 23:17:01 bookchin /USR/SBIN/CRON[24910]: (root) CMD ( cd / && run-parts /etc/cron.hourly) kind of garbage.

• Find words in many files

  - by ant2009

  Hello, I am looking for this struct messages_sdd_t and I need to search through a lot of *.c files to find it. However, I can't seen to find a match as I want to exclude all the words 'struct' and 'messages_sdd_t'. As I want to search on this only 'struct messages_sdd_t' The reason for this is, as struct is used many times and I keep getting pages or search results. I have been doing this without success: find . -type f -name '*.c' | xargs grep 'struct messages_sdd_t' and this find . -type f -name '*.c' | xargs egrep -w 'struct|messages_sdd_t' Many thanks for any suggestions,

• Is it possible for DNS to direct traffic to different ports?

  - by Giffyguy

  Right now I have a DNS CNAME record that makes ftp.angryoctopus.net an alias for the actual FTP URL domain, which is angryoctopus.net:65021 The goal is that a client should be able to type ftp://ftp.angryoctopus.net/ in their browser's address bar, and be directed to Angry Octopus's FTP site on my server - which is hosted at port 65021. Of course the hostname won't resolve. Is it possible to accomplish this type of alias somehow, or am I just beating a dead horse? This reminds me of DynDNS, which I used a few years ago for something-or-other. How does DynDNS spoof ports like that, and can I immitate it to make this work?

• Chrome and Firefox freeze when I begin typing

  - by mschulze

  Last night, chrome began freezing whenever I tried to type anything. After a fresh reinstall the problem went away but it is back again this morning. I installed Firefox as a substitute browser but it has the same problem. I cannot even get past the homepage because typing in the u r l bar freezes both programs. Last night internet explorer froze once too, but it has not happened since. Disabling shock-wave does not have any affect on the problem. Because it is happening across multiple browsers, I do not believe it to be caused by any extensions I have installed on Chrome. I also tried running Chrome as a new user and the problem still occurred. I can open any apps or web sites that are on my homepage, but as soon as I try to type anything the program freezes. Any ideas?

• View unknown content-types in Firefox?

  - by dirtside

  A certain URL on my server returns Content-Type: application/json. The filename ends with .phtml, so whenever I go to it, Firefox 3.5 asks me if I want to save it or open it with another program. But the answer is neither; I want to view it in Firefox as if it was text/plain. Suggestions? The Applications tab of the Preferences window doesn't give this as an option for the "PHTML" type which now is listed in there (ever since I tried to open it with no external program).

• Windows Server 2008: Limit UDP/TCP packets per IP or ban

  - by WBAR

  How I can limit UDP/TCP packets per IP send to my host (or better PORT) per second or minute ? Would be nice to ban that IP for 12/24 hours or even for ever. I got Windows Server 2008 and I'm very poor in Windows administration but quite good in Linux. EDIT: By basic problem is that They sending a lot of rubbish UPD and TCP packets.. TCP packets without SYNCH, fragmented UDP packets so my servers stop responding.. So I need to cut off users (IPs) sending more than X packets per second. I need solution witch provides me, somehow, configurable: X packets of certain type (UDP, TCP or both - lets say parameter named Z ) are allowed to be received by IP on Y port, otherwise this packet should be DROPPED. My virtual hosts are hosted by VirtualBox and I'm able to forward all incoming packets certain type and certain port to the specific Virtual Host, but I need to DROP them before my VirtualBox receive them.

• Kaspersky processing error Explorer.exe (recycle bin)

  - by aeternus828

  I get daily critical errors from Kaspersky involving Explorer.exe... The file in question is almost always in the Recycle Bin, or something on the desktop. Here is an example error detail: Event type: Processing error Application\Name: EXPLORER.EXE Application\Path: C:\WINDOWS\ Application\Process ID: 2364 Application\Options: C:\windows\Explorer.EXE Component: File Anti-Virus Result\Description: Processing error Object: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\$RIKKQKS Object\Type: File Object\Path: C:\$Recycle.Bin\S-1-5-21-1403139956-787289773-2644151291-500\ Object\Name: $RIKKQKS Reason: Read error Google searches didn't offer much insight, so I thought I'd ask here if anyone has encountered a similar situation. Not sure if it's a bug, something to be concerned about, or an easy fix, etc. I usually just empty the recycle bin for a temporary fix, but would like to get to the root of the error. Thoughts?

• 40k Event Log Errors an hour Unknown Username or bad password

  - by ErocM

  I am getting about 200k of these an hour: An account failed to log on. Subject: Security ID: SYSTEM Account Name: TGSERVER$ Account Domain: WORKGROUP Logon ID: 0x3e7 Logon Type: 4 Account For Which Logon Failed: Security ID: NULL SID Account Name: administrator Account Domain: TGSERVER Failure Information: Failure Reason: Unknown user name or bad password. Status: 0xc000006d Sub Status: 0xc0000064 Process Information: Caller Process ID: 0x334 Caller Process Name: C:\Windows\System32\svchost.exe Network Information: Workstation Name: TGSERVER Source Network Address: - Source Port: - Detailed Authentication Information: Logon Process: Advapi Authentication Package: Negotiate Transited Services: - Package Name (NTLM only): - Key Length: 0 This event is generated when a logon request fails. It is generated on the computer where access was attempted. The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network). The Process Information fields indicate which account and process on the system requested the logon. The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols. - Key length indicates the length of the generated session key. This will be 0 if no session key was requested. On my server... I changed my adminstrative username to something else and since then I've been inidated with these messages. I found on http://technet.microsoft.com/en-us/library/cc787567(v=WS.10).aspx that the 4 means "Batch logon type is used by batch servers, where processes may be executing on behalf of a user without their direct intervention." which really doesn't shed any light on it for me. I checked the services and they are all logging in as local system or network service. Nothing for administrator. Anyone have any idea how I tell where these are coming from? I would assume this is a program that is crapping out... Thanks in advance!

• How do I set up a bridge on Ubuntu GNOME 14.04

  - by NJRandy

  I found a guide for setting up a bridge in Fedora and was trying this: $ nmcli connection delete p33p1 $ nmcli connection add con-name br0 type bridge ifname br0 autoconnect yes $ nmcli connection add con-name p33p1 type bridge-slave ifname p33p1 master br0 autoconnect yes I found that $ nmcli con delete uuid [uuid here] accomplished the first step. nmcli connection does not have an 'add' action in this distribution. Please help me do the 2nd and 3rd steps. Context: I am trying to set up a virtual machine. I believe this is a necessary step for the VM to access my network and the internet. Please feel free to correct me if I am wrong! BTW, I am a linux newbie, tech oldie. Thank you.

• How does formatting works with a PowerShell function that returns a set of elements?

  - by Steve B

  If I write this small function : function Foo { Get-Process | % { $_ } } And if I run Foo It displays only a small subset of properties: PS C:\Users\Administrator> foo Handles NPM(K) PM(K) WS(K) VM(M) CPU(s) Id ProcessName ------- ------ ----- ----- ----- ------ -- ----------- 86 10 1680 412 31 0,02 5916 alg 136 10 2772 2356 78 0,06 3684 atieclxx 123 7 1780 1040 33 0,03 668 atiesrxx ... ... But even if only 8 columns are shown, there are plenty of other properties (as foo | gm is showing). What is causing this function to show only this 8 properties? I'm actually trying to build a similar function that is returning complex objects from a 3rd party .Net library. The library is flatting a 2 level hierarchy of objects : function Actual { $someDotnetObject.ACollectionProperty.ASecondLevelCollection | % { $_ } } This method is dumping the objects in a list form (one line per property). How can I control what is displayed, keeping the actual object available? I have tried this : function Actual { $someDotnetObject.ACollectionProperty.ASecondLevelCollection | % { $_ } | format-table Property1, Property2 } It shows in a console the expected table : Property1 Property2 --------- --------- ValA ValD ValB ValE ValC ValF But I lost my objects. Running Get-Member on the result shows : TypeName: Microsoft.PowerShell.Commands.Internal.Format.FormatStartData Name MemberType Definition ---- ---------- ---------- Equals Method bool Equals(System.Object obj) GetHashCode Method int GetHashCode() GetType Method type GetType() ToString Method string ToString() autosizeInfo Property Microsoft.PowerShell.Commands.Internal.Format.AutosizeInfo autosizeInfo {get;set;} ClassId2e4f51ef21dd47e99d3c952918aff9cd Property System.String ClassId2e4f51ef21dd47e99d3c952918aff9cd {get;} groupingEntry Property Microsoft.PowerShell.Commands.Internal.Format.GroupingEntry groupingEntry {get;set;} pageFooterEntry Property Microsoft.PowerShell.Commands.Internal.Format.PageFooterEntry pageFooterEntry {get;set;} pageHeaderEntry Property Microsoft.PowerShell.Commands.Internal.Format.PageHeaderEntry pageHeaderEntry {get;set;} shapeInfo Property Microsoft.PowerShell.Commands.Internal.Format.ShapeInfo shapeInfo {get;set;} TypeName: Microsoft.PowerShell.Commands.Internal.Format.GroupStartData Name MemberType Definition ---- ---------- ---------- Equals Method bool Equals(System.Object obj) GetHashCode Method int GetHashCode() GetType Method type GetType() ToString Method string ToString() ClassId2e4f51ef21dd47e99d3c952918aff9cd Property System.String ClassId2e4f51ef21dd47e99d3c952918aff9cd {get;} groupingEntry Property Microsoft.PowerShell.Commands.Internal.Format.GroupingEntry groupingEntry {get;set;} shapeInfo Property Microsoft.PowerShell.Commands.Internal.Format.ShapeInfo shapeInfo {get;set;} Instead of showing the 2nd level child object members. In this case, I can't pipe the result to functions waiting for this type of argument. How does Powershell is supposed to handle such scenario?

• Cannot open root device xvda1 or unknown-block(0,0)

• accidentally concatenate a large file on a remote system

  - by Dan

  Every once in a while on a computer I'm ssh'd into, I will accidentally type "cat largefile.txt" and my screen will start rushing with text for the next 10 minutes. I'm always working in a screen session, so my current solution is to just log out and then log back in, and since it can go 100X faster when I'm logged out, it'll finish in the short time it takes me to type my password in again. Is there a better way? Either involving the fact I'm in a screen session? Or a way to do this within SSH? What doesn't work: detaching from the screen session (doesn't respond until file is done outputting) trying command to move to a different window in the screen session (also doesn't respond) typing ctrl+C to kill cat command (also doesn't respond, probably because the command is done and the buffers just have to catch up)

• Windows 7 PC refuses to join domain

  - by Alex

  So, we're wiping clean all PCs at our office and migrating them to a new server cluster and a new domain. Last night I tested on PC and it mostly worked except it refuses to join to the domain. Now, our domain is named like EXAMPLE.COM. When I just type EXAMPLE the PC can't find the domain controller, even though I can ping it find. If I type EXAMPLE.COM it seems to work. How can I get it to work with just EXAMPLE? That's how I got all the new servers int he cluster to work (about 20 of them) and I haven't had any issues... The only difference between the Windows 7 PC(s) and the servers is that the clients will be on a 10.0.3.X network where as the servers are on a 10.0.1.X network. Oh, the domain controller and all the other servers are Windows Server 2008 R2. Suggestions will be highly appreciated!

• Remote access to BIOS?

  - by j-g-faustus

  I have a home server running headless (i.e. without a monitor), using ssh for remote access. This works fine most of the time, but I still need a graphics card and still need to drag out a monitor whenever I have to access BIOS, (re-)install the OS and similar. I know that there are business servers that let you control everything remotely (over Ethernet), including power up and BIOS access. Is this type of functionality available for "prosumer" class hardware? If so, where does it sit - should I look for motherboard support, a PCI-e card or an external device? And does this type of functionality have a name, so I know what to google for?

• How can I get ssh-agent working over ssh and in tmux (on OS X)?

  - by Rich

  I have a private key set up for my github account, the passphrase to which is, I believe, stored in OS X's keychain. I certainly don't have to type it in when I open a terminal window and enter ssh [email protected]. However, when I'm running bash over an ssh session, or locally inside a tmux session, I have to type in the passphrase every single time I attempt to ssh to github. This question suggests that a similar problem exists with screen, but I don't really understand the issue well enough to fix it in tmux. There's also this page which includes a fairly complicated solution, but for zsh. EDIT: In response to @Mikel's answer, from a local terminal I get the following output: [~] $ echo $SSH_AUTH_SOCK /tmp/launch-S4HBD6/Listeners [~] $ ssh-add -l 2048 [my key fingerprint] /Users/richie/.ssh/id_rsa (RSA) [~] $ typeset -p SSH_AUTH_SOCK declare -x SSH_AUTH_SOCK="/tmp/launch-S4HBD6/Listeners" Whereas over ssh or in tmux I get: [~] $ echo $SSH_AUTH_SOCK [~] $ ssh-add -l Could not open a connection to your authentication agent. [~] $ typeset -p SSH_AUTH_SOCK bash: typeset: SSH_AUTH_SOCK: not found echo $SSH_AGENT_PID returns nothing whatever shell I run it from.

  I need files ending with ".pdf" or ".png"; here's my attempt: find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*[pdf|png]' this incorrectly includes files ending with "Apdf", "Zpdf", etc. (missing literal dot before file extension) I tried adjusting the pattern to: find /Users/robottinosino/Desktop/_PublishMe_ -type f -regex '.*\.[pdf|png]' but then no results are returned.

• What's the best scenario for using a wireless router with Comcast Business Class

  - by Buck

  Just had Comcast Business Class internet installed (usage details at bottom of post). During the call to order I asked about the hardware they'd be providing and was told it was a docsis 3 modem that I'd have to pay $7.00/month for. Figuring I'd have to buy a router anyway, I decided to get my own modem - a Surfboard SB6121 Docsis 3. I called in to tech support to ask some questions and learned that the modem they would have provided DID have a router built in. It's an SMCD3G-CCR. It's not wireless (we need wireless). The guy explained that it was better to have their hardware here because if there's a problem with our service and we're using our own hardware, chances are they'll blame it on our hardware and do nothing since they don't support it. He explained that I could still hang my own wireless router off their modem/router and if we ever had any service problems, we'd be able to plug directly into their hardware and they'd be able to tell where the problem is and they wouldn't be able to pawn it off onto "customer provided equipment". That all said, a few questions: 1. Am I better off returning my Surfboard modem and getting the Comcast one? If I get a wireless router and plug into one of the ethernet ports of the Comcast device, should I NOT plug anything else into the Comcast device since it would be a different network from anything connecting via the wireless router? Is that correct? Given that I know VERY LITTLE about networking and setting up hardware like this... since I need wireless and will HAVE to get a wireless router to work with this Comcast device, do I need to do anything with the settings of the Comcast device? Do I use security on the Comcast device or the wireless router or both? Any suggestions or anything I need to think about, given this scenario, in order to use a business-type voip service like RingCentral or Jive or Nextiva? Any recommendations on a wireless router for this scenario? We are running 2 PCs (possibly 3-4 in the future) - could be wired for the time being if needed but would prefer wireless; would like to have a networked hard drive and a networked printer; NEED business-type VOIP service asap for 2 phone lines. Would like to hook up some IP cameras at some point (but not the kind that require static IPs since I don't have one nor do I plan to pay Comcast another $15/month for one). I don't have or plan to have any type of web servers or anything like that. Want to use WPA or WPA2 security and take advantage of the NAT feature of the router for additional protection (that's the extent of my networking knowledge).

• Share history in multiple zsh shell

  I am trying to setup zsh so that it shares command history between different zsh sessions: in multiple tabs in multiple gnome-terminals in different screen sessions I have put this in .zshrc #To save every command before it is executed (this is different from bash's history -a solution): setopt inc_append_history #To retrieve the history file everytime history is called upon. setopt share_history but that does not work. e.g. I type 1 command: gedit afile and then I go to and zsh and type history. I don't see gedit afile. output of 'setopt' is % setopt nohistbeep histexpiredupsfirst histfindnodups histignorealldups histignoredups histignorespace histnostore histreduceblanks histsavenodups histverify incappendhistory interactive monitor promptsubst sharehistory shinstdin zle How can I achieve this?

• Weird windows quirk when renaming file

  - by Roy Rico

  Hi, I am finding when I try to rename a file in windows 7, i typically select the file i want to rename, hit F2 (rename) and type the new name. I've been getting this weird bug which the while file name gets selected again, sometimes right in the middle of me typing. I can sit there and watch it reselect the entire filename every second or so as if someone is invisibly hitting control+a while type. I have tried making sure that my keys aren't being pressed, and also have even gotten a new keyboard and this problem still consists. I know it'll probably be a long shot, but just hoping someone's seen this issue and has a resolution. UPDATE: This is on a desktop machine, not a laptop, so there's no issue with Trackpad.

• Why do some PDFs lag in Adobe Acrobat?

  - by Coldblackice

  I have a handful of PDFs open. One of them in particular is extremely laggy, almost to the point of being unreadable. When I scroll through its pages, it's almost like an extreme version of v-sync being turned off. Very choppy. Overall system resources are plentiful, and all of the other PDFs cruise up and down with no stuttering or problems. I've tried closing and reopening the problem PDF to no avail. It's a small PDF, only 3MB in size, with no graphics (only programming code snippets). Surely, it must be some type of problem with the specific PDF (I'll try opening it in another PDF-viewing program, rather than Acrobat X). Possible corruption? Could there be some type of GPU/hardware-acceleration intervening going on? I've never heard of such with PDF-viewing.
