• Python module: Trouble Installing Bitarray 0.8.0 on Mac OSX 10.7.4

• SSH session becomes unresponsive when logged into Ubuntu Server virtual machine using VirtualBox

  - by nickbart

  Hi everyone, I'm really at my wits end here, so I'm hoping someone here can help me. I have a virtual machine running Ubuntu Server 9.10. It's just a small development environment so I can keep my code separate from the test and production environments. I am running it through VirtualBox 3.1.6 on a laptop running Ubuntu Desktop 9.10. I have it set up with a bridged network connection and it is bridged to my laptop's wireless adapter. We have no wired connections in this office. I boot up the VM and everything is fine. I can SSH into it using gnome-terminal and for a while everything is Kosher. Then seemingly randomly, the SSH terminal session with hang. No error message, nothing; it just becomes unresponsive. If I go to the VirtualBox terminal I find the VM itself is perfectly fine. It can ping and I can SSH out with it. If I restart the networking on the VM the SSH session in my gnome-terminal will most of the time become responsive again. Here's an interesting point, the SSH session will sometimes die right in the middle of me typing something (this points to it not being an idle session issue) and if I go to the VirtualBox terminal and restart the networking and then return to my gnome-terminal SSH session I find that it will come back to life and what I typed when the session hung originally will magically type itself in to the buffer. So, my input is getting stored somewhere and just can't make its way to the VM until the networking on the VM is restarted. I've tried different versions of VirtualBox and used vmdk images and vdi images and nothing seems to work. I can't tell if the problem is with my laptop, VirtualBox, or the Ubuntu Server VDI. Is there anyway to debug this issue? Or has anyone out there seen anything similar? Your help is much appreciated. Nick

• is ksplice production ready?

  - by faultyserver

  I would be interested to hear the serverfault community's experiences with Ksplice in production. Quick blurb from wikipedia: Ksplice is a free and open source extension of the Linux kernel which allows system administrators to apply security patches to a running kernel without having to reboot the operating system. and Ksplice can, without restarting the kernel, apply any source code patch that only needs to modify the kernel code. Unlike other hot update systems, Ksplice takes as input only a unified diff and the original kernel source code, and it updates the running kernel correctly, with no further human assistance required. Additionally, taking advantage of Ksplice does not require any preparation before the system is originally booted (the running kernel does not need to have been specially compiled, for example). In order to generate an update, Ksplice must determine what code within the kernel has been changed by the source code patch. So a few questions: How has the stability been? any odd issues that you have encountered with its 'rebootless live patching' of the kernel? Kernel panics or horror stories? I have been running it on a few test systems and so far its been working as advertised, but I am interested in what other sysadmins experiences have been with Ksplice before going 'all in' and deploying this on our production servers. So, anybody using Kspice in production? update: hmm, not seeing any real activity on this question after a couple of hours (besides some kind upvotes and favs). Maybe to spark some activity I'll also ask a few more questions and see if we can get this discussion going... "If you are aware of Ksplice, is there a reason you are not using it?" "Do you feel its still too bleeding edge, unproven or untested?" "Does Ksplice not fit well within your current patch-management system?" "Do you hate having systems that have long (and secure) uptimes?" ;-)

• Amazon EC2 instance missing Network Interface

  - by Sergiks

  I am running Linux on a t1.micro instance at Amazon EC2. Once I noticed bruteforce ssh login attemtps from a certain IP, after litle Googling I issued the two following commands (other ip): iptables -A INPUT -s 202.54.20.22 -j DROP iptables -A OUTPUT -d 202.54.20.22 -j DROP Either this, or maybe some other actions like yum upgrade perhaps, caused the follwing fiasco: after rebooting the server, it came up without the Network Interface! I only can connect to it through AWS Management Console JAVA ssh client - via local 10.x.x.x address. Console's Attach Network Interface as well as Detach.. are greyed out for this instance. Network Interfaces item at the left does not offer any Subnets to choose from, to create a new N.I. Please advice, how can I recreate a Network Interface for the instance? Upd. The instance is not accessible from outside: cannot be pinged, SSH'ed or connected by HTTP on port 80. Here's the ifconfig output: eth0 Link encap:Ethernet HWaddr 12:31:39:0A:5E:06 inet addr:10.211.93.240 Bcast:10.211.93.255 Mask:255.255.255.0 inet6 addr: fe80::1031:39ff:fe0a:5e06/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1426 errors:0 dropped:0 overruns:0 frame:0 TX packets:1371 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:152085 (148.5 KiB) TX bytes:208852 (203.9 KiB) Interrupt:25 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) What is also unusual: a new micro instance I created from scratch, with no relation to the troubled one, was not pingable too.

• How to install a desktop environment onto Ubuntu Server -- but without internet access or a CDROM?

  - by James

  I am playing around with a computer which has no CDROM drive or internet access and I have installed Ubuntu Server onto it. I have that all up and running nicely but now I'd like to install Xfce, GNOME or something similar so I can load up a desktop environment from the command line if I wish. Obviously with internet access or a CDROM, this would be a simple task of using apt-get and it finding & retrieving the packages for me, I assume, but I do not have either. I do however have a USB drive and I have used Unetbootin to make it into a bootable drive with the Ubuntu Server disk image files on there. I have mounted the USB drive to /media/usb0 and tried the command "sudo apt-cdrom add -d /media/usb0" to get apt to recognise the USb drive as an "Ubuntu CD" -- a source of package files but apt-get doesn't seem to be finding Xfce.. I try "sudo apt-get install xfce" and "sudo apt-get install xfce4" but neither find the package.. I would prefer to have Xfce but GNOME would be OK too.. My question is, am I doing something wrong? I figured that the Ubuntu Server disk (or rather, my Ubuntu Server USB drive) might not have any desktop environment packages on there so I tried the Xubuntu Desktop disk too (again, from my USB drive). I tried "sudo apt-get install xubuntu-desktop" but it couldn't find the package - even though it is listed under the /casper/ directory in some MANIFEST file. Anyone see where I'm going wrong? Maybe apt-get install is looking somewhere other than my USB drive? Maybe my commands are wrong? Maybe the disks don't even have the desktop environments on!? Thanks in advance guys, any input would be much appreciated. Cheers - James

• scalable yet doable small-medium office network

  - by Jared

  Hello, I'm studying up with both Microsoft and Cisco literature and I must say, my head is starting to get clustered up (pun intended). I've made a quick network diagram of a theoretical company... Company1 owns Company 2 and Company 3, which are all under separate rooms and networks, but must be able to share a few resources such as files or printers. Given the amount of info out there and best practices, I thought about posting here to get suggestions and see what would the pro's do. I can read and read all day and implement on my own, but if I dont get some outside input, how will I know if I'm doing something wrong, right? anyway, please take a look and see if this is an over-complicated network or a lackluster design for a small-medium company of about 35 people and lets say they will be double that number by end of the year... :) Using win2k3, esxi, windows xp. FCS - forefront client security, ACS - access control system, SPCWK - spiceworks, XCH - Exchange Im not allowed to post an image yet, so here's the link ---- GLIFFY IMAGE Flame suit is on just in case people get mad at me for making an "abomination". I'd really want to get the general overview properly before I dive into the more complicated things

• How to convert Markdown files to Dokuwiki, on a PC

  - by Clare Macrae

  I'm looking for a tool or script to convert Markdown files to Dokuwiki format, that will run on a PC. This is so that I can use MarkdownPad on a PC to create initial drafts of documents, and then convert them to Dokuwiki format, to upload to a Dokuwiki installation that I have no control over. (This means that the Markdown plugin is no use to me.) I could spend time writing a Python script to do the conversion myself, but I'd like to avoid spending time on this, if such a thing exists already. The Markdown tags I'd like to have supported/converted are: Heading levels 1 - 5 Bold, italic, underline, fixed width font Numbered and unnumbered lists Hyperlinks Horizontal rules Does such a tool exist, or is there a good starting point available? Things I've found and considered I initially thought that txt2tags would be helpful, but although it can write both markdown and Dokuwiki, it is very tied to its own specific input format I've also seen Markdown2Dokuwiki, and although I'd certainly be willing to use a sed script, even on a PC, this only supports a tiny, tiny part of Markdown's syntax. python-markdown2 also sounded promising, but it only writes out HTML. pandoc - but it doesn't support Dokuwiki output MultiMarkdown - does not appear to support Dokuwiki output

• Can't Configure IBM 8275-416 Switch Via Serial

  - by Sean M

  I am attempting to configure an IBM 8275-416 switch (I found a manual here) via serial connection. However, when I connect with HyperTerminal, the output contains a lot of garbage characters. It's pretty much unusable, because there's enough layout-breaking text-gunk that it's very difficult to determine what's actually being displayed. . I was able to reset the switch to factory defaults via the terminal interface, so I know that it's not entirely broken. It also performs basic functions all right (i.e., you plug in clients and Ethernet cables - they can connect to clients plugged into other ports) - but I'd like it to do more than that (VLANs yay). I don't know if its in-band UI is operational or not, because I can't get the terminal interface to behave well enough to properly turn on the web/SNMP UI. So that's not available. Things I've tried: - Changing the encoding: HyperTerminal lets me choose between Standard JIS and Shift-JIS. Neither setting fixes the issue. - Checking emulation settings: The manual demands VT100, 19200 baud, 8 data bits, and such: I have faithfully applied these settings, both in HyperTerminal's settings and in the properties of the COM1 port in Device Manager (connecting from a Windows machine). - Restoring to factory defaults: See above. Things that it could be, but that seem unlikely: - Cabling: Couldn't find a proper null-modem cable, so used two 232-to-RJ45 adapters. But if it was a problem with the cable, wouldn't it be more likely to not connect or do input at all, rather than just garble the text? Since I was actually able to perform the reset-to-factory defaults operation, I don't think it's this. - Device as a whole broken: It is a decade and change old, so it's possible that it's just dying slowly. Again, though, it seems like there would be more symptoms than just garbled text in the terminal. What else can I try to get a sane interface to this switch?

• Port 22 is not responding

  - by Emanuele Feliziani

  I'm trying to make the jump to VPS from shared hosting for better performances and greater flexibility, but am stuck with the fact that I can't access the machine via ssh. First of all, the machine is a CentOS 6.3 cPanel x64 with WHM 11.38.0. Sshd is running (it appears in the current running processes). Making a port scan I see that port 22 is not responding. Port 21 is, but I am not able to access the machine via ftp (I think it's a security measure, but I don't know where to disable/enable it). So, I'm stuck in WHM and have no way to access the configuration of the machine, neither via ssh nor with ftp/sftp. When trying to connect with ssh via Terminal I only get this: ssh: connect to host xx.xx.xxx.xxx port 22: Operation timed out I also tried to access with the hostname instead of the IP address and it's the same. There seem to be no firewall in WHM and I have whitelisted my home IP address to access ssh, though there were no restrictions in the first place. I have been wandering through all the settings and options in WHM for several hours now, but can't seem to find anything. Does anybody have a clue as to where I should start investigating? Update: Thanks everyone. It was in fact a matter of firewall. There was a firewall not controlled by the WHM software. I managed to crack into the console from the vps control panel (a terrible, terrible java app that barely took my keyboard input) and disabled the firewall altogether running service iptables stop so that I was able to access the console via ssh with the terminal. Now I will have to set up the firewall again because the command I ran looks like having completely wiped the iptables. Can you recommend any newby-friendly resource where I can learn how to go about this and what should I block? Or should I just go with something like this: http://configserver.com/cp/csf.html ? Thanks again to everyone who helped me out.

• Clarification for setting up SSH terminal access on Cisco IOS

  - by Matt Malesky

  I'm attempting to set up SSH on a Cisco 2811 and having some difficulties. The first step to this should be running crypto key generate rsa I seem to be missing this though: better#crypto key generate rsa ^ % Invalid input detected at '^' marker. better# Furthermore, the only available commands I have in the crypto key namespace are lock and unlock, which seem to indicate a locked keypair (for which I don't know the password): better#crypto key ? lock Lock a keypair. unlock Unlock a keypair. better#crypto key unlock ? rsa RSA keys better#crypto key unlock rsa %% Please enter the passphrase: %% Unlocking failed. . better# More or less, I'm asking what exactly this might mean, and if I actually do have certificates already here (used router)? Otherwise, how can I solve this? It's my first time configuring this feature, but I definitely believe it's part of my IOS.

• Best Practices for adding Exchange Archive to current 3 server setup

  - by ADquestion

  I'm looking to add an Archive Database (which I know is just a Mailbox Database) to our current Exchange 2010 environment. I have done this in the past at a previous job, but we had a simpler setup than at this current job. I've been trying to find some best practices to make sure it's setup in an ideal way, but so far not finding the details I would prefer. Hoping someone on here can give me a few pointers. Currently we have a 3 server setup, Server1, Server2 and Server3. Three databases of course, DB1, DB2 and DB3. We have a DAG setup between them. Server1 has DB1 and DB3 on it, DB1 is not active, DB3 is active. Server2 has DB1 and DB2 on it, both are active. Server3 has DB2 and DB3 on it, both are not active. All three servers are virtual (VMware). Each one is setup identical to the other as follows: C:\ 60GB - OS E:\ 600GB - DB (currently only 90GB used, pointing to Datastore just for Server2) F:\ 200GB - Log (2GB used, pointing to same Datastore as above) G:\ 200GB - Restore (0 used, pointing to same Datastore as above) The drives are all set to Thin Provisioning, and it looks as though I have 600GB of available space. They have not been on Exchange that long and only have about 70GB worth of PSTs to import back in that will be going to the Archive Database, plus anything older than 2 years from their current inbox that will be moved into there. I was considering placing the Archive DB on the E:\ drive of Server3 (only) like the current DB, but wasn't sure if that was acceptable. I don't plan on setting the Archive DB up with the DAG, just plan on having it as a single repository for older emails and manually back it up every now and then. If anyone has any suggestions on this I would appreciate it the input. I've done it on a slightly smaller scale before and it worked well, but like to think it through before pulling the trigger, especially at a new job. :) Thanks again!

• CLOSE_WAIT sockets burst - perhaps because of iptables settings?

  - by Fabrizio Giudici

  I have an Ubuntu 12.04 server virtual box where basically the installed software and configuration are the default ones, plus the installation of a jetty 6 server which servers a few websites. To keep things simple I didn't install apache httpd and used iptables for exposing jetty (which runs on the 8080 port) to the port 80. These are the results of /sbin/iptables -t nat -L Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain INPUT (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination REDIRECT tcp -- anywhere localhost tcp dpt:http redir ports 8080 REDIRECT tcp -- anywhere Ubuntu-1104-natty-64-minimal tcp dpt:http redir ports 8080 Chain POSTROUTING (policy ACCEPT) target prot opt source destination I must confess I have a shallow comprehension of how iptables works, in particular for the different kind of chains. This thing works, but sometimes I have an explosion of sockets that stay permanently in CLOSE_WAIT state. I know about what this state means, but since I didn't write the code that manages servlets (they are handled by jetty) I can't fix the problem by patching my code. Eventually the amount of CLOSE_WAIT sockets builds up and makes the server not responsive, so I have to restart jetty. I've looked around for similar problems wth CLOSE_WAIT, and only found cases related to the programmer's code, or problems with Tomcat, not Jetty. I was wondering whether they could be related to a partially broken iptables configuration (the alternative is a bug in Jetty 6, but I first want to exclude other possible causes). Thanks.

• Host name change breaking http? Fedora

  - by Dave

  OK so I have been messing around on my development server. It has been a while since I have had my head in linux and I suspect I have broken something. I have SSH running and that is working fine. I also have HTTP and I had FTP running also. Earlier today I decided I wanted to rename the machine so I updated the /etc/hosts file and /etc/sysconfig/network. I also changed the server name in the httpd.conf. I rebooted the machine and reconnected to SSH fine. Later I was messing around with the FTP service (trying to tighten up the user security) and when i tried to connect remotely to FTP no joy, it said cannot connect. I thought that was weird but had planned to remove ftp as we will be using github so removed ftp and moved on. Then I tried to connect to the website but major fail. even connecting to the IP address is failing. I used lynx to connect to the localhost and there was my site so something going on at server level. I thought maybe something up with iptables but I have not changed them but tried adding http but still no joy.

Any ideas?

• Quickly set up a Windows Server and automatically install and configure software

  - by Chris

  Yesterday I spent far too much time downloading and installing software on Windows Server 2008. I only had to install a simple server for SQL Server 2008 Express using Microsoft's Web Platform Installer, then configure it to enable remote connections. Everything had to be attended, wasting my time. On a Linux system, this would be trivial to automate, but this is Windows. I do this very rarely, but in the future I would like to make this take as little time as possible. I could do a disc image with everything I installed and configured, but is there a better way? I know nothing of advanced deployment techniques on Windows. Ideally I would like to be able to remotely re-install the OS, or have an unattended install (which I know is possible). Any tips to make the software I need easier to and install and configure with minimal interaction necessary would be helpful. I don't expect everything I asked for to be possible and easy to do. Basically, If any part of it can be done quicker or at least without user input, that's what I'm looking for.

• Routing table on Linux not respected

  - by MRHaarmann

  I have a very specific problem, building a Linux VPN endpoint (with external VPN Gateway), which should route certain networks over the tunnel, others via default gateway. The Linux VPN should do a NAT on the outgoing connections for the VPN peers. Setup is as following: Internet gateway LAN 192.168.25.1/24 VPN Gateway LAN 10.45.99.2/24 (VPN tunnel 10.45.99.1 to net 87.115.17.40/29, separate connection to Internet) Linux VPN Router eth0 192.168.25.71/24 eth0:503 10.45.99.1/24 Default 192.168.25.1 route to 87.115.17.40/29 via 10.45.99.2 (send_redirects disabled, ip_forward enabled) Linux clients (multiple): eth0 192.168.25.x/24 Default 192.168.25.1 route to 87.115.17.40/29 via 192.168.25.71 Ping to the machines via tunnel from the VPN Router is working. Now I want to establish a routing from my clients over the VPN gateway and the client packet gets routed to 192.168.25.1 ! traceroute output shows the packets get routed to 192.168.25.71, but then to 192.168.25.1. So the route is not respected in forward ! IPTables and Routing: ip route show 87.115.17.40/29 via 10.45.99.2 dev eth0 10.45.99.0/24 dev eth0 proto kernel scope link src 10.45.99.1 192.168.25.0/24 dev eth0 proto kernel scope link src 192.168.25.71 default via 192.168.25.1 dev eth0 iptables -A INPUT -i eth0:503 -j REJECT iptables -t nat -A POSTROUTING -o eth0:503 -j MASQUERADE iptables -A FORWARD -i eth0:503 -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 192.168.25.0/24 -o eth0:503 -j ACCEPT So what is wrong with my setup ? The route is chosen correctly from localhost, but all the clients get forwarded to the Internet GW. thanks for helping, Marcus

• Not able to access external Hard disk

  - by Jash Jacob

  I have a 1TB External Hard drive which I'm currently not able to access. When I open the External drive in Finder, It shows it's empty. When I use the option to "Get Info", I get the dialog box stating it has about 300GB Free. Tried to get into the External Drive using Terminal, I had no luck. Checking in Disk Utility, It showed that I have many number of files but ZERO folder. I tried to "repair disk", in the process the external Drive got unmounted in between the process. I checked this drive on Windows. I was able to open almost all the folders but I wasn't able to copy anything onto the external drive. One folder caused my windows computer to hang, So i connected the drive back onto my MacBook Pro and tried to access the drive through terminal (this time it worked!) and then I tried to delete the folder with rm command, I got an "input/output error" What should i do to recover the files in that folder? How can i access my external drive on my mac

• Would like to change audio codec, but keep video settings with ffmpeg

  I have a video for which I'd like to convert the audio codec to AAC 320 kbps / 44.100 kHz.

• emacs ORG-mode "headless" export-as commands?

  - by Seamus

  When I use org-export-as-latex or org-export-as-html orgmode turns my buffer into a .tex file or .html file. But I don't want all the extra junk that it adds to the file: I want to handle the documentclass and everything myself and just \input the org mode generated file. (Or the analogous things for html with php). So if my org file just has: * Section - Stuff - Things I want the org mode command to output just \section{Section} \begin{itemize} \item Stuff \item Things \end{itemize} Without any of the extra \tableofcontents junk that ORG adds to it. I know I could define my own kind of #+LaTeX_CLASS that could add the packages I want and so on, but I don't want to do things that way (and that wouldn't remove the \maketitle or the spurious \vspace* that ORG insists on inserting. Is there a command to do this "headless" parsing and converting? I had a look but it's not obvious from the documentation. Presumably some low level ORG command is doing the parsing and converting I want, but I couldn't find what it was called from looking at the docs and C-h pages... This is not a question about HTML or LaTeX but about emacs ORG mode. So don't kick it off to some other site...

• Live Screencast under Linux

  - by OmnipotentEntity

  I was having some difficulty with running a Live Screencast under Linux. I've found jtvlc and tried using that, but whenever I use it the stream comes out either blank or lagged with extremely high latency. I have a fast internet connection and a fast computer, but am I perhaps taxing it too much? Any ideas on what I could possibly be doing wrong? # 1. Get an account on http://www.justin.tv/ # 2. Copy streaming key from: http://www.justin.tv/broadcast/adv_other # 2. Install VLC: http://www.videolan.org/vlc/ # 3. Get Win/Mac/Lin Stream Client: \ # http://apiwiki.justin.tv/mediawiki/index.php/Linux_Broadcasting_API # 4. Adjust the vlc parameters to your liking and run VLC like this #!/bin/bash cvlc screen:// --input-slave=pulse:// \ --screen-width 1920 \ --screen-height 1080 \ --screen-fps 5 \ -v input_stream \ --sout='#duplicate{ dst="transcode{ scale=1, venc=x264{ keyint=60 }, vcodec=h264, vb=600, acodec=mp4a, ab=32, channels=2, samplerate=22050 } :rtp{dst=127.0.0.1,port=1234,sdp=file:///tmp/vlc.sdp} "}' \ --sout-transcode-threads=4 & sleep 2 # 5.

• Flash drive suddenly died. Why? Can I recover it?

  - by mg

  Hi, I have a flash drive that I used not too much but, after few month of inactivity, it died. I know that flash drives have a limited write cycles but I am sure that this is not the problem. I tried to create a new partition table and format the drive nothing worked.
