• DD-WRT PPTP VPN problem

  - by Tobias Tromm

  I try to configure a DD-WRT as a PPTP client. The VPN Server is Windows Server 2003. This is my scenario: The Windows 2003 Server has set to give to the VPN Client the 10.0.0.81 fixed IP and to add a network route to the remote home. At the remote home I have changed the PPTP Options at DD-WRT to make the connection. The VPN connection is successfully established. ...and Windows successfully add the route to the remote home 192.168.2.X. From the remote home I can successfully access any computer from the VPN server side. The problem is when I try to access the remote home from the Server side. From Server side I only can access\ping DD-WRT ( by VPN Client IP - 10.0.0.81). What's wrong? How I need to do to be a site-to-site VPN? This is what happen when I try to tracert the remote home from local home.

• Fixing partitions and Installing BackTrack

  - by Josh

  My whole problem started when I started trying to install Backtrack(3 or 4) Backtrack was trying to install itself over my entire windows partition (Which I had combined into one when I installed windows 7). So I booted back into windows 7 on my netbook (eee pc 1000 HE btw) I went into disk-manager with the aim of making a partition to install backtrack on but came out with a really screwed up drive. So I had two partions when I started: the windows system partition, and then my main partition and they were blue in diskmanager (I think that has something to do with formatting). After I went through the steps to make a 10 GB FAT32 partition for backtrack I had about five partitons one called PE: that I have no Idea what it is the windows system file, my main partiton 10 GB unallocated space, and two other partions under 50MB each that are both unused space. And they were all converted to simple volumes (Green instead of blue). And backtrack still wants to erase my entire drive. Question number 1: How do I get it back to the way it was? Question 2: How to I get backtrack to dual boot on my netbook?

• Linux Kernel Packet Forwarding Performance

  - by Bob Somers

  I've been using a Linux box as a router for some time now. Nothing too fancy, just enabling forwarding in the kernel, turning on masquerading, and setting up iptables to poke a few holes in the firewall. Recently a friend of mine pointed out a performance problem. Single TCP connections seem to experience very poor performance. You have to open multiple parallel TCP connections to get decent speed. For example, I have a 10 Mbit internet connection. When I download a file from a known-fast source using something like the DownThemAll! extension for Firefox (which opens multiple parallel TCP connections) I can get it to max out my downstream bandwidth at around 1 MB/s. However, when I download the same file using the built-in download manager in Firefox (uses only a single TCP connection) it starts fast and the speed tanks until it tops out around 100 KB/s to 350 KB/s. I've checked the internal network and it doesn't seem to have any problems. Everything goes through a 100 Mbit switch. I've also run iperf both internally (from the router to my desktop) and externally (from my desktop to a Linux box I own out on the net) and haven't seen any problems. It tops out around 1 MB/s like it should. Speedtest.net also reports 10 Mbits speeds. The load on the Linux machine is around 0.00, 0.00, 0.00 all the time, and it's got plenty of free RAM. It's an older laptop with a Pentium M 1.6 GHz processor and 1 GB of RAM. The internal network is connected to the built in Intel NIC and the cable modem is connected to a Netgear FA511 32-bit PCMCIA network card. I think the problem is with the packet forwarding in the router, but I honestly am not sure where the problem could be. Is there anything that would substantially slow down a single TCP stream?

• Is there any way for ME to improve routing to an overseas server?

  - by Simon Hartcher

  I am trying to make a connection to a gaming server in Asia from Australia, but my ISP routes my connection through the US. Tracing route to worldoftanks-sea.com [116.51.25.54]over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms 192.168.1.1 2 34 ms 42 ms 45 ms 10.20.21.123 3 40 ms 40 ms 43 ms 202.7.173.145 4 51 ms 42 ms 36 ms syd-sot-ken-crt1-ge-6-0-0.tpgi.com.au [202.7.171.121] 5 175 ms 200 ms 195 ms ge5-0-5d0.cir1.seattle7-wa.us.xo.net [216.156.100.37] 6 212 ms 228 ms 229 ms vb2002.rar3.sanjose-ca.us.xo.net [207.88.13.150] 7 205 ms 204 ms 206 ms 207.88.14.226.ptr.us.xo.net [207.88.14.226] 8 207 ms 215 ms 220 ms xe-0.equinix.snjsca04.us.bb.gin.ntt.net [206.223.116.12] 9 198 ms 201 ms 199 ms ae-7.r20.snjsca04.us.bb.gin.ntt.net [129.250.5.52] 10 396 ms 391 ms 395 ms as-6.r20.sngpsi02.sg.bb.gin.ntt.net [129.250.3.89] 11 383 ms 384 ms 383 ms ae-3.r02.sngpsi02.sg.bb.gin.ntt.net [129.250.4.178] 12 364 ms 381 ms 359 ms wotsg1-slave-54.worldoftanks.sg [116.51.25.54] Trace complete. Since I think it will be unlikely that my ISP will do anything, are there any ways to improve my routing to the server without them having to intervene? NB. The game runs predominately over UDP, so I believe most low ping services are out of the question, as they rely on TCP traffic.

• Time drift in Cloud Server - need to mainpulate GRUB config

  - by Aditya Advani

  We are hosting a VPS on a popular host and are experiencing a regular time drift of several minutes a day forward (approx 7). Linux Kernel: 2.6.18-164.11.1.el5 GNU/Linux Distro: CentOS release 5.4 (Final) We reached out to our hosting provider and their support advised us " This is a known issue with Cloud Servers. To fix this you will need to add one line to your grub config located at: /boot/grub/menu.lst The line you need to add is: noapic nolapic divider=10 nolapic_timer This should correct this issue. You will need to restart after this is added in. " Because I am wary of manipulating grub, mostly I'm terrified that our server may fail to restart - I ask you guys, the pro *nix admins - where exactly in this file does the recommended insertion below: # line from 1&1 for time syncing issue (Case 5163) noapic nolapic divider=10 nolapic_timer go? Please specify where exactly, and whether the order of commands is or is not important. Why is the block below "title CentOS ..." indented? If someone could give me an overview of how this works or point me to a resource that's easy to follow, that's what I'm looking for immediately, a light overview or basic understanding of what I;m doing. If GRUB and bootloaders are a deep dark treasure trove of kernel hacking or something, that's great well-recommended in-depth resources are also very welcome. This is my current /boot/grub/menu.lst # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file #boot=/dev/sda # serial --unit=0 --speed=57600 terminal --timeout=5 serial console timeout=5 title CentOS (2.6.18-164.11.1.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/hda1 console=tty0 console=tty initrd /boot/initrd-2.6.18-164.11.1.el5.img MOST IMPORTANT: I need to know where in the file above it is appropriate to paste the suggested line so I can confidently restart my VPS after manipulating GRUB config

• MySQL is killing the server IO.

  - by OneOfOne

  I manage a fairly large/busy vBulletin forums (running on gigenet cloud), the database is ~ 10 GB (~9 milion posts, ~60 queries per second), lately MySQL have been grinding the disk like there's no tomorrow according to iotop and slowing the site.

• What's hogging my CPU?

  - by endolith

  Ubuntu's System Monitor applet shows 100% CPU usage continuously. If I click it, the resources tab shows it at 100% continuously, too. If I go to processes, though, to find out which process is the culprit, there is nothing above 10%. If I run top there is nothing above 10%. I try killing lots of things, but it continues at 100%. How can I find out what's hogging the CPU? This is an unusual situation on a computer I use daily, that normally only hits 100% CPU when I'm doing something that requires it (like loading 32 Firefox tabs) after which it goes back to a normal idle level. It's not a new install or anything. It shouldn't be maxed out. I'm not sure when it started or if I changed something that caused it to happen. Normally I would use top or System Monitor and find the process that had gone out of control, but I can't find anything with those tools this time. It persists after reboots and everything. And the processor is obviously hot, so it's not an erroneous reading. Update: I tried killing any process I saw active again, and killing vino-server finally fixed the problem, even though it never went above 5%. I had enabled Remote Desktop a few days ago (and have obviously now disabled it). How did it manage to use 100% CPU while top only showed it as 5% or so? How do I identify the culprit in the future? Looks like I'm not the only one: Still a problem in both jaunty & karmic. Interestingly, both System Monitor & htop do not show the sum of individual processes being anywhere near 100% cpu.

• BES Express - configure MDS to push messages from 3rd party web application

  - by Max Gontar

  Hi! I have developed IIS web service to send PAP messages using Blackberry Push API over MDS. And there is an application installed on device, configured to receive push messages on appropriate port. Everything works well on MDS simulator. But it's not working well in real environment: I have installed BES Express and register several devices. I can browse MDS url with appropriate port, so url is correct. Also port enabled for reliable pushes is used in push message and in device application. Here is MDS simulator log: <2011-01-12 14:00:03.456 EET>:[272]:<MDS-CS_MDS>:<DEBUG>:<LAYER = SCM, EVENT = PapServlet: request from 0:0:0:0:0:0:0:1 564 bytes...> <2011-01-12 14:00:03.476

• VLAN with trunk to avoid broadcast storm in a network with redundant paths

  - by liv2hak

  I have 6 Juniper switches (EX - 2200) connected to each other as shown in the network topology. I have two PC's that I am using PC1 - (used for configuring the 6 switches via minicom) PC2 - to monitor the traffic between the switches via the Ports that are marked with arrows in the diagram. STEP 1: I create a new vlan On Switch 3 (SW3) that includes Port 12 and Port 22. I also assign l3-interface to the vlan (vlan_2) with ip address - 192.168.1.7. Now I plug-in Port 0 of Switch 3 on PC2. Now I try pinging 192.168.1.7 from PC2 (192.168.1.10) I want to know what will happen? My postulation is that I will not be able to ping SW3 from PC2.This is because SW3 (Port 12 and Port 22) is a part of a vlan_2 and vlan_2 logically breaks up broadcast domains and so 192.168.1.7 will not be reachable from 192.168.1.10. Now I have an l3-interface on SW1 with IP 192.168.1.1 using default vlan( vlan-id 0). Similarly I have enabled IP on SW2 - 192.168.1.2 SW3 - 192.168.1.3 SW4 - 192.168.1.4 SW5 - 192.168.1.5 SW6 - 192.168.1.6 all using default vlan. I create VLAN2 with the following configuration SW3 - Port 12,Port 22. SW6 - Port 14 I create VLAN3 with the following configuration SW3 - Port 0 SW6 - Port 0 I also configure a VLAN trunk between SW3 and SW6 using the following commands. edit interfaces ge-0/0/12 set unit 0 family ethernet-switching port-mode trunk edit interfaces ge-0/0/12 set unit 0 family ethernet-switching vlan members all There is a redundant path in the network as the loop between SW3 and SW6 is closed.There is no broadcast storm in the network? What is the reason for this? I have not enabled STP or RSTP.still there is no broadcast storm.what is the reason for this. (Please ignore the CISCO symbol on the switches in the diagram.All swithes are Junper EX 22-00.)

• nginx+mysql5 loadtesting configuration strangeness

  i am trying to setup a new server running on debian6 and trying to make it work smooth under load. i ve used a wordpress site as a test object, and tried the configurations on http://blitz.io. when i increase the mysql max_connections from 50 to 200 lots of timeouts start to occur. but on 50 , no timeouts and pretty well response times. nginx configuration is fine , i tuned the config so i dont see errors. so i presume it's related to the other configuration options of my.cnf . i read some about options but still cant find what max_connections problem is all about. btw, the server has 16gb of ram and a fine i7 cpu. here is the current my.cnf [client] port = 3306 socket = /var/run/mysqld/mysqld.sock [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] wait_timeout=60 connect_timeout=10 interactive_timeout=120 user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp language = /usr/share/mysql/english skip-external-locking bind-address = 127.0.0.1 key_buffer = 384M max_allowed_packet = 16M thread_stack = 192K thread_cache_size = 20 myisam-recover = BACKUP max_connections = 50 table_cache = 1024 thread_concurrency = 8 query_cache_limit = 2M query_cache_size = 128M expire_logs_days = 10 max_binlog_size = 100M [mysqldump] quick quote-names max_allowed_packet = 16M [mysql] #no-auto-rehash # faster start of mysql but no tab completition [isamchk] key_buffer = 16M thanks in advance. i asked this question on SO but it's closed as off topic so i believe this is a SF question.

• Rebooting access point via SSH with pexpect... hangs. Any ideas?

  - by MiniQuark

  When I want to reboot my D-Link DWL-3200-AP access point from my bash shell, I connect to the AP using ssh and I just type reboot in the CLI interface. After about 30 seconds, the AP is rebooted: # ssh [email protected] [email protected]'s password: ******** Welcome to Wireless SSH Console!! ['help' or '?' to see commands] Wireless Driver Rev 4.0.0.167 D-Link Access Point wlan1 -> reboot Sound's great? Well unfortunately the ssh client process never exits, for some reason (maybe the AP kills the ssh server a bit too fast, I don't know). My ssh client process is completely blocked (even if I wait for several minutes, nothing happens). I always have to wait for the AP to reboot, then open another shell, find the ssh client process ID (using ps aux | grep ssh) then kill the ssh process using kill <pid>. That's quite annoying. So I decided to write a python script to reboot the AP. The script connects to the AP's CLI interface via ssh, using python-pexpect, and it tries to launch the "reboot" command. Here's what the script looks like: #!/usr/bin/python # usage: python reboot_ap.py {host} {user} {password} import pexpect import sys import time command = "ssh %(user)s@%(host)s"%{"user":sys.argv[2], "host":sys.argv[1]} session = pexpect.spawn(command, timeout=30) # start ssh process response = session.expect(r"password:") # wait for password prompt session.sendline(sys.argv[3]) # send password session.expect(" -> ") # wait for D-Link CLI prompt session.sendline("reboot") # send the reboot command time.sleep(60) # make sure the reboot has time to actually take place session.close(force=True) # kill the ssh process The script connects properly to the AP (I tried running some other commands than reboot, they work fine), it sends the reboot command, waits for one minute, then kills the ssh process. The problem is: this time, the AP never reboots! I have no idea why. Any solution, anyone?

• HA Proxy won't load balance my web requests. What have I done wrong?

  - by Josh Smeaton

  I've finally got HA Proxy set up and running in a way I think I want. However, it is not load balancing the web requests it receives. All requests are currently being forwarded to the first server in the cluster. I'm going to paste my configuration below - if anyone can see where I may have gone wrong, I'd appreciate it. This is my first stab at configuring web servers in a *nix environment. First up, I have HA Proxy running on the same host as the first server in the apache cluster. We are moving these servers to virtual later on, and they will have different virtual hosts, but I wanted to get this running now. Both web servers are receiving their health checks, and are reporting back correctly. The haproxy?stats page correctly reports servers that are up and down. I've tested this by altering the name of the file that is checked. I haven't put any load onto these servers yet. I've just opened up the URLs on several tabs (private browsing), and had several co-workers hit the URL too. All of the traffic goes to WEB1. Am I balancing incorrectly? global maxconn 10000 nbproc 8 pidfile /var/run/haproxy.pid log 127.0.0.1 local0 debug daemon defaults log global mode http retries 3 option redispatch maxconn 5000 contimeout 5000 clitimeout 50000 srvtimeout 50000 listen WEBHAEXT :80,:8443 mode http cookie sessionbalance insert indirect nocache balance roundrobin option httpclose option forwardfor except 127.0.0.1 option httpchk HEAD health_check.txt stats enable stats auth rah:rah server WEB1 10.90.2.131:81 cookie WEB_1 check server WEB2 10.90.2.130:80 cookie WEB_2 check

• Joining two routers together, but I have no access to the second router, although I know it's IP address and Gateway

  - by JohnnyVegas

  I have temporarily moved into a rented apartment for 4 months, which has wireless. The trouble I am having is that the access points here are wifi only and no RJ45 and I need to use RJ45 to connect some equipment that I am working with. I have purchased an RT-N66U and installed Tomato (shibby ver. 1.28) and successfully replaced the existing access point, but now I want to enable the access point that I have replaced as it links wirelessly to 3 others. Can I plug in a cable from the access point to my RT-N66U and get it to access the internet via my router? I have no access to the existing wireless access point, and don't want to reset it as it's not mine. There is another router situated in the roof somewhere which I also have no access to, but it's supplying my RT-N66U internet and I most definitely have a double-nat, which although isn't the best way of doing things I am limited with what I can do. Any suggestions on routing tables, vlans etc would be helpful, but I have no experience in these fields before - but I know the tomato firmware can cater for this. My router is set to IP 10.0.1.1 and dhcp is 10.0.1.100-200 The wireless access point address was 192.168.1.2 but this was assigned by the router in the roof which has the address 192.168.1.1. There is a cable from this router going to a wall socket which I now have my RT-N66u attached to via the WAN port. I understand it's scruffy and it isn't the way to do things but I have tried to ask for the admin details but as the wireless network is looked after by a third party and nobody knows their details I am stuck with this dilemma. I could buy three wireless access points and replace the existing but this isn't what I want to do, and although I have installed plenty of DD-WRT wireless repeater bridges they simply don't work here for some unknown reason. The phone line here is very noisy too and I don't have the rights to install ADSL in a building that isn't mine, and 3G coverage isn't good enough either. Thanks for your time

• Domino to Exchange 2007 (or 2010) Design Concerns?

  - by NickToyota

  Today we got the executive green light to proceed with changing from a Domino platform to Exchange. The business prefers Exchange for a messaging platform. (even though IMO IBM Domino is fine - if it aint broke, don't fix it but it was not my call). I have been put in charge of Domino to Exchange process goes smoothly as possible. I have also been told to put together costs for this project. I have some questions and concerns re: network design, licensing, costs: The current setup is as follows. 1 HQ office (100 users), 1 secondary office (50 users), 5 branch offices (under 10 users). 5 different email domains Windows Server 2003 functional level with a few 2008 R2 Servers Lotus Domino Notes Servers (one in each office) Ironmail Appliance Public Domino Web Mail server Majority G5+ Proliant Servers Domino Blackberry Enterprise license and server No VoIP phones What are the basic hardware requirements for Exchange 2007 or 2010? Can I simply purchase a single physical server? Will each office require an Exchange server or possibly additional servers (roles)? How is email routed to the smaller branch offices? Standard or Enterprise licenses? The business has been running Domino (messaging and application services) for over 10 years and also want Exchange to support email services, Blackberry, Outlook Web Access, possibly support for iPhone devices. Thank you Serverfault universe.

• Running multiple services on different servers with IPv6 and a FQDN

  - by Mark Henderson

  One of the things NAT has permitted us to do in the past decade is split physical services onto different servers whilst hiding behind a single interface. For example, I have example.com behind a NAT on 192.0.2.10. I port-forward :80 and :443 to my web server. I'm also port forward :25 to my mail server, and :3389 to a terminal server and :8080 to the web interface of my computer that downloads torrents, and the story goes on. So I have 5 port forwardings going to 4 different computers on example.com. Then, I go and get me some neat IPv6. I assign example.com an IPv6 address of 2001:db8:88:200::10. That's great for my websites, but I want to go to example.com:8080 to get to my torrents, or example:3389 to log on to my terminal server. How can I do this with IPv6, as there is no NAT. Sure, I could create a bunch of new DNS entries for each new service, but then I have to update all my clients who are used to just typing example.com to get to either the website or the terminal server. My users are dumber than two bricks so they won't remember to connect to rdp.example.com. What options do I have for keeping NAT-style functionality with IPv6? In case you haven't figured it out, the above scenario is not a real scenario for me, or perhaps anyone yet, but it's bound to happen eventually. You know, with devops and all.

• Changing MX records in named zone file

  - by Paul England

  I forgot how all this works. I have a GoDaddy account, using my own DNS and whatnot. I'm having trouble getting my email to work. They said I need to update my MX records. basically, I have the following. 184.168.30.42 is the domain's IP address, obviously. gamengai.com. 14400 IN NS n1 gamengai.com. 14400 IN NS n2 ns1 14400 IN A 184.168.30.42 ns2 14400 IN A 184.168.30.42 gamengai.com. 14400 IN A 184.168.30.42 localhost 14400 IN A 127.0.0.1 ftp 14400 IN A 184.168.30.42 www 14400 IN A 184.168.30.42 mail 14400 IN A 184.168.30.42 subdomain 14400 IN A 184.168.30.42 gamengai.com 14400 IN MX 10 mail Mail doesn't work though... they say to make the following change: 0 smtp.secureserver.net 10 mailstore1.secureserver.net So should the last line point to mailstore1.secureserver.net instead of mail in the last field? What about the other line? I had this working at one time, but it's totally gotten away from me. It's a virtual dedicated server and their support for this stuff is pretty bad... almost as bad as my admin skills since I went the programmer route.

• Workstations cannot see new MS Server 2008 domain, but can access DHCP.

  - by Radix

  The XP Pro workstations do not see the new replacement domain upon boot; they only see their cached entry for the old (server 2003) domain controller. The old_server is not connected to the network. I have DHCP working with the same scope as the old_server. In my "before-asking" search for a solution I came across the following two articles, and I recall doing things as suggested by the articles. http://www.windowsreference.com/windows-server-2008/how-to-setup-dhcp-server-in-windows-server-2008-step-by-step-guide/ http://www.windowsreference.com/windows-server-2008/step-by-step-guide-for-windows-server-2008-domain-controller-and-dns-server-setup/ The only possible issue is: I was under the impression that the domain netbios needed to match the DC's netbios. The DC netbios is city01 while the domain's FQDN is city.domain.org (I think this is mistaken and should have been just domain.org) But, the second link led me to a post which I believe answers my question. I did as they instructed by opening Local Area Connection Properties, then selecting TCP/IPv4 and setting the sole preferred DNS server to the local hosts static IP (10.10.1.1). Search for "Your problems should clear up" for the post I'm referencing: http://forums.techarena.in/active-directory/1032797.htm Have I misunderstood their instructions? I am hoping to reach the point where I can define users and user groups. Also, does TechNet have a single theoretical overview document I could read. I really don't like treating comps as magic. I will be watching this closely and will quickly answer any questions. If I've left anything out it is because I did not know it was needed. PS: I am loath to ask obviously basic questions, but I am tired and wish to fix this before tomorrow. Also, this is my first server installation, thank you for your help.

Here's how I'm trying to do it [manually now]: /sbin/netconfig modify -v -i tap0 -s openvpn <<-EOF INTERFACE='tap0' DNSSERVERS='10.10.0.1' EOF And here's the verbose output: debug: lockfile created (/var/run/netconfig.pid) for PID 5530 debug: lockfile created debug: write new STATE file /var/run/netconfig//tap0/netconfig0 debug: Module order: dns-resolver dns-bind dns-dnsmasq nis ntp-runtime debug: dns-resolver module called debug: Static Fallback debug: Use NetworkManager policy merged settings debug: exec get_dns_settings: /var/run/netconfig/NetworkManager.netconfig debug: get_dns_settings: service 'NetworkManager' => rank '1' debug: get_dns_settings: DNS_SEARCHLIST_1='mydomain.com' debug: get_dns_settings: DNS_SERVERS_1='192.168.0.1' debug: exit get_dns_settings: /var/run/netconfig/NetworkManager.netconfig debug: write_resolv_conf: ' mydomain.com ' ' 192.168.0.1 ' debug: No changes for /etc/resolv.conf debug: dns-bind Module called debug: dns-dnsmasq Module called debug: nis Module called debug: Static Fallback debug: Use NetworkManager policy merged settings debug: exec get_nis_settings: /var/run/netconfig/NetworkManager.netconfig debug: exit get_nis_settings: /var/run/netconfig/NetworkManager.netconfig debug: set_nisdomainname: eth0 24 debug: set_nisdomainname: => yes debug: set_nisdomainname: old[]=, new[24]= debug: format_yp_conf called with : debug: Using static fallback debug: format_static[0] called debug: No changes for /etc/yp.conf debug: nis domainname '' is up to date debug: ntp-runtime Module called debug: Static Fallback debug: Use NetworkManager policy merged settings debug: exec get_ntp_settings: /var/run/netconfig/NetworkManager.netconfig debug: get_ntp_settings: NTP_SERVER_LIST='' debug: exit get_ntp_settings: /var/run/netconfig/NetworkManager.netconfig I've been trying to find something relevant on the web, but failed to do so. I have no other clue on how to progress with this issue. Any thoughts?

• Puppet file transfer slow

  - by Noodles

  I have a puppet master and slaves in different datacenters. The latency between them is ~40ms. When I run "puppet agent --test" on a slave to apply the latest manifest it takes ~360 seconds to finish. After doing some digging I can see the main cause of the slow down is file transfers. It seems it's taking ~10 seconds to transfer each file. The files are only small (configuration files) so I can't understand why they would take so long. This is an example of a file in my manifest: file { "/etc/rsyncd.conf" : owner => "root", group => "root", mode => 644, source => "puppet:///files/rsyncd/rsyncd.conf" } Running puppet-profiler I see this: 10.21s - File[/etc/rsyncd.conf] It also seems I cannot update more than one server at once using puppet. If I run two servers at the same time then puppet takes twice as long. I have changed the puppet master from using webrick to mongrel, but this doesn't seem to help. This is making deploying changes painful. A simple config change can take an hour to roll out to all servers.

• How to wire 20 computers and 20 phones and 1 server into LAN?

  - by John Smith

  I have currently 3 switches Two Netgear JFS524 with 24 slots, One Belkin with 16 slots. Server DSL Internet Router. Main question is how to connect switches together, two Netgear's are next to each other, yet one is about 100 feet away and holds about 5 computer and 5 phones. If i connect them with only 1 wire will that limit bandwidth? e.g. all 23 computers will be limited to speed of one CAT5e cable? If i connect switches with 2 cables will this give speed boost? What's the ideal scenario should i just move the third switch next to other two? Will the speed of computer connected to white switch be same as computer connected to top switch? Will moving white switch right next top switch and having 16 wires comming 100 feet instead of 1 wire comming 100 feet make it faster? EDIT 1: I actually have NETGEAR ProSafe GS105 Gigabit switch its only has 4 ports in it though, you think i can have use of it in current setup? Like connect all 3 switches and server into it and keep internet router and phone server on one of the slower switches EDIT 2: Everyone mention gigabit switches, but will they do any difference with 10/100 network cards? I then have to use gigabit cards in every computer too? I could in server perhaps, but users will be 10/100

• nameserver spoiling avahi multicast name resolution of .local domain

  - by Doug Coburn

  After trying to ping a machine on my local network, I noticed that I was trying hit address 66.152.109.24. This is an external public address. Resolution should have occurred via avahi mDNS. I ran dig to see how the name resolution worked and my quest/centurylink name server was retuning results for my .local domain queries! I tried a random name and got the same ip address result. $ dig jakdafj.local ; <<>> DiG 9.8.1-P1-RedHat-9.8.1-3.P1.fc15 <<>> jakdafj.local ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 58410 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;jakdafj.local.
