• How do I increment strings in Vim?

  - by Chas. Owens

  I can increment integers in Vim using <Ctrl>-a. The docs seem to say that if I set nrformats to "octal,hex,aplha" (which I am trying to do with :set nrformats="octal,hex,alpha") then <Ctrl>-a will increment a to b, 007 to 010, and 0x09 to 0x0f, but those examples are not working for me (I just a get a beep for a, 007 turns into 008, and 0x09 turns into 0x10).

• NFS mount mounted inside another NFS mount disappears randomly

  - by espenfjo

  I have quite an odd issue where my nested NFS mounts just disappear randomly from time to time. The fstab entries look somewhat like this: nfs:/home /home/nfs rw,hard,intr,rsize=32768,noatime,nocto,proto=tcp 0 0 nfs:/bigdir /home/bigdir nfs rw,hard,intr,rsize=32768,noatime,nocto,proto=tcp,bg 0 0 The issue is that from time to time the "/home/bigdir" folder will be empty, even though mtab think that the share is still mounted. nfsstat et. al. do also think the share is still mounted. Only thing that works is by unmounting, and then (re)mounting the bigdir share. The server side is a NetApp. The client side is RHEL5.5, 2.6.18-194 kernel (Yes, I know 5.8 is out, but as far as I can see there are no erratas for this particular issue). I can use various hacks like automount, or mounting it to another path and then using --mount bind, but I would like to fix the underlying issue. -- Best regards Espen Fjellvær Olsen

• Windows 2008 R2 IPsec encryption in tunnel mode, hosts in same subnet

  - by fission

  In Windows there appear to be two ways to set up IPsec: The IP Security Policy Management MMC snap-in (part of secpol.msc, introduced in Windows 2000). The Windows Firewall with Advanced Security MMC snap-in (wf.msc, introduced in Windows 2008/Vista). My question concerns #2 – I already figured out what I need to know for #1. (But I want to use the ‘new’ snap-in for its improved encryption capabilities.) I have two Windows Server 2008 R2 computers in the same domain (domain members), on the same subnet: server2 172.16.11.20 server3 172.16.11.30 My goal is to encrypt all communication between these two machines using IPsec in tunnel mode, so that the protocol stack is: IP ESP IP …etc. First, on each computer, I created a Connection Security Rule: Endpoint 1: (local IP address), eg 172.16.11.20 for server2 Endpoint 2: (remote IP address), eg 172.16.11.30 Protocol: Any Authentication: Require inbound and outbound, Computer (Kerberos V5) IPsec tunnel: Exempt IPsec protected connections Local tunnel endpoint: Any Remote tunnel endpoint: (remote IP address), eg 172.16.11.30 At this point, I can ping each machine, and Wireshark shows me the protocol stack; however, nothing is encrypted (which is expected at this point). I know that it's unencrypted because Wireshark can decode it (using the setting Attempt to detect/decode NULL encrypted ESP payloads) and the Monitor Security Associations Quick Mode display shows ESP Encryption: None. Then on each server, I created Inbound and Outbound Rules: Protocol: Any Local IP addresses: (local IP address), eg 172.16.11.20 Remote IP addresses: (remote IP address), eg 172.16.11.30 Action: Allow the connection if it is secure Require the connections to be encrypted The problem: Though I create the Inbound and Outbound Rules on each server to enable encryption, the data is still going over the wire (wrapped in ESP) with NULL encryption. (You can see this in Wireshark.) When the arrives at the receiving end, it's rejected (presumably because it's unencrypted). [And, disabling the Inbound rule on the receiving end causes it to lock up and/or bluescreen – fun!] The Windows Firewall log says, eg: 2014-05-30 22:26:28 DROP ICMP 172.16.11.20 172.16.11.30 - - 60 - - - - 8 0 - RECEIVE I've tried varying a few things: In the Rules, setting the local IP address to Any Toggling the Exempt IPsec protected connections setting Disabling rules (eg disabling one or both sets of Inbound or Outbound rules) Changing the protocol (eg to just TCP) But realistically there aren't that many knobs to turn. Does anyone have any ideas? Has anyone tried to set up tunnel mode between two hosts using Windows Firewall? I've successfully got it set up in transport mode (ie no tunnel) using exactly the same set of rules, so I'm a bit surprised that it didn't Just Work™ with the tunnel added.

• Cannot connect to WEBrick on home network

  - by Chris Stewart

  I'm an Android developer and often my applications require server-side code. I typically use Ruby on Rails for the web app, and during development will run the server on my local machine (Mac OS X) with WEBrick. In the morning when I get to the office, I'll run ifconfig in the console to see what IP my laptop has been given that day. I'll use that IP in my Android app when making requests to the web app in question. This all works fine, when I'm in my office. When I get home, I attempt to do the same thing, find my laptop's IP via ifconfig, set it in my app's config file, but the destination can never be found. To exclude my app from the set of hurdles, I attempt to visit the web server IP (e.g., http://192.168.1.4:3000) from my phone's browser, and it cannot connect. If I try from my laptop, which is running the web server, it works fine. If I try from another machine, on the same network, it also is unable to connect. Given this, I think I've narrowed it down to some kind of configuration in my home network, but I frankly have no idea what the cause could be. I don't have anything special at home, your basic Verizon FiOS router/modem with everything connected via Wi-Fi (Wi-Fi for both phone and laptop at work as well, fyi). I've tried disabling the firewall on my Verizon router, enabling port forwarding, and just about everything else I could do for port 3000, and nothing has changed. Dear Server Fault geniuses, please help a poor developer out. :) Edit: Some follow up items to add. My Mac's firewall is not active, and all incoming requests are allowed. I've also verified on my phone and laptop, that they're on the same network (192.168.1.4 Mac, 192.168.1.9 Phone). I have no idea why this isn't working. Edit 2: I went into System Preferences, enabled Web Sharing, and tried to view the website from my phone and it didn't connect. So it's not WEBrick or related to Rails. The firewall on my machine is off and the firewall on my router is off. Edit 3: Some progress. I set up port forwarding for port 3000 to my laptop, found the external IP, and used that and it connected fine. So, there's definitely something not quite set up correctly on my internal network.

• Configure host access rights in OpenLDAP

  - by Anonymous Coward

  I've set up an OpenLDAP-Server to authenticate users to our Ubuntu-servers. The authentication works quite well but I'd like to restict the user's access to certain servers. I know this can be done through nss_base_something in the client's ldap.conf. However, this requires the group restrictions to be specified on the client. I wonder if the restrictions can be set completely in OpenLDAP. If it is, I'd like to know how. Thanks, AC

• Kickstart: ifcfg-eth0 file genorated by kickstart when install from network but from initrd when install form USB

  - by dooffas

  When I install Fedora 19 with a kickstart file and via network, the generated ifcfg-eth0 file is genorated by the kickstart: # Generated by parse-kickstart However if I use the same kickstart file and install via a USB stick, the ifcfg file is generated by initrd. # Generated by dracut initrd The line in the kickstart file to set the network settings is as follows: network --device=eth0 --bootproto=dhcp --hostname=SOMEHOSTNAME Is there away to keep network device settings set in the kickstart file when not installing via network?

• Windows Server 2008 R2 DFS Root Namespace Required?

  - by caleban

  I would prefer to set up our DFS such as: \domain.local\users \domain.local\customers \domain.local\support etc. Is this a problem? Do I need to instead set all of the above folders as targets under a root such as: \domain.local\files\users \domain.local\files\customers \domain.local\files\support Other than the path being shorter in the top example, which is what I would prefer, is there a difference in functionality in Windows DFS between the two examples shown? Thanks in advance.

• sudo logs date with user's locale, apparently. How do I make it use "C" locale?

  - by jae

  I have sudo set to log to /var/log/sudo.log. I've noticed that when the locale was set to "de_DE.UTF-8", it logged a localized date ("Mär" for "März") instead of "C" locale ("Mar" for "March"). How do I make it log the date independent of the user's locale? Where the ** is that documented, anyway? Or am I halluzinating? (Could be, since I've got a major cold... ;-))

• Network connection through a wall

  - by BCS

  I have a place where I want to set up a network connection through a normal residential wall where I can't cut any holes. I don't want to just set up a wireless system. Does anyone make a device that you place on either side of a wall to hook up a connection? Preferably something that can do 100Mb full duplex and can't be eavesdropped on with common hardware?

• Windows Event Log wrong Source column value

  - by O.O

  In the Event Viewer in Windows 7 there is a Source column that is set by my Windows Service application. The value is set to TOS and usually when a log entry is associated to my application, it has TOS as the Source column value. However, when the service fails to start (or some other kind of error occurs) I get a Source of one of the following values: Application Error Service Control Manager .NET Runtime I don't understand why the value is not always TOS Also, is it possible to force it to use TOS every time?

• Enforce user time restrictions to log out or off from Windows 7

  - by javamonkey79

  How can I limit the time spent on the computer or force a log out from a Windows 7 machine? I used to use Windows Steady State to limit users (kids) from being on too long but SteadyState does not work with Windows 7 Home Premium and is discontinued. Is there a way to set this up in Windows 7 where it will kick off a user after a set time? Or perhaps there's an alternative program that can help limit the time one user is at the computer.

• tomcat 6 start mode setting for production [windows]

  - by Ryan Fernandes

  Tomcat 6 (as a windows service) seems to have a 'Start Mode' with options of 'java, jvm or exe' which can be set via the Tomcat Monitor (system tray icon). if I set this to 'java', I can see a forked 'java.exe' process for tomcat, if I chose either of the other two, I dont see a separate process. Anyway, would like to know if anyone has any information about what these settings mean and which one would be most appropriate in production.

• Why are unicode characters not rendering correctly

  - by sw1nn

  Background: I have some unicode characters in my prompt (git status markers essentially) I'm running urxvt under xfce on arch linux. I'm using DejaVu Sans Mono for Powerline font, specified via .Xresources line: URxvt*font: xft:DejaVu Sans Mono for Powerline:pixelsize=14 When I start urxvt the unicode characters do not render correctly. For example ? renders as â However, if I then start a new urxvt from inside the first terminal everything renders correctly. There doesn't appear to be any difference in the environment between the two terminals. What could be the difference between the first invocation and the nested invocation? I suspect the font is not correct in the 'outer' instance, but I'm unsure how to check the font of a running X window screenshot demonstrates the problem: Note: I moved this question from serverfault.com - i hope this site is more appropriate

• Windows PE autorun scripts

  - by tearman

  I've set up a Windows Preinstallation Environment on a USB Thumb Drive (version from the latest iteration of the Windows Automated Install Kit/WAIK), and I'm working on getting a deployment environment set up. However, we'd like to make it so our Level 1 technicians can use the deployment system, and because of this, I've written several batch files to minimize the amount of command line work the technicians have to do. Is there a way I can get these scripts to autorun after the PE environment has finished initializing?

• Is there any way to get tree organisation for Windows 7 file explorer favorites?

  - by fostandy

  In XP there was a MenuBar called Favorites which seemed to be based on Internet Explorer Favorites. It was fantastic because it allowed for very fast tree style navigation (if set up correctly you could navigate it using first letter keystrokes, so to access a shortcut named "videos" in a folder named "files" was as quick as Alt-A f v) This was removed in Vista (and imo generally regressed the file explorer). This was fine because I never used it, but I'm resigned to eventually embracing the inevitability that is Windows 7. Dealing with a single non-nested list of favourites is pretty painful to me as I have quite a lot of them. Is there a way to make a tree like favorites structure in Windows 7? My fingers are crossed.
