  • Internal+external interfaces with multiple default gateways on win2003

    - by fileitup
    Im trying to set up several web servers for a load balanced cluster and need to have each server connected to the internal network (for load balancing) as well as to an external network (internet - for administration). I have two NICs but since I cant set two default gateways I have the external gateway as default and the internal as a route rule. This setup only works half way - the internal network is fine but I cant log in from outside or see the web from the box. If I switch the gateways remote login/web will work, but the internal wont. Im sure someone encountered this before but wasnt able to find anything online. Any help will be appreciated.

  • Amazon EC2, fastest way to get a node into an existing cluster

    - by imaginative
    I'm new to Amazon AWS. A lot of the time I hear about people folks spawning instances and almost instantly putting them behind a load balancer and into an existing cluster. In the traditional world of managed machines, this would include provisioning hardware, installing an OS, configuring the network on the machine and once the network is available, use a tool of your choice such as CFengine, Puppet or Chef to bootstrap the machine based on its class. It seems like there are "shortcuts" that are able to get a server of a particular class up and running in Amazon EC2. If I have a particular stack running on my server, such as erlang, tomcat6 etc.. what's the fastest way to get these up and running and hooked into Amazon's load balancer? From network, to software stack to kernel tuning? Is it a combination of creating an AMI then running a tool like Puppet against the new instance? Any idea

  • best way to enlarge system partition

    - by yuvi
    I have a problem - I need to enlarge my system partition. I mean - when I initially installed Ubuntu, I split the partition so I have 15GB for system and the rest (around 400) pointed at /home/. This is very useful if anything goes wrong someday and I want to format and completely re-install Ubuntu without losing any of my actual data. The problem is, 15GB isn't enough, so it seems. I already moved /var/ and /opt/ folder to /home/, adding symlinks at root, but I'm still at 86% usage and I'm having performance issues (mostly when booting or running a VM). I can use Ubuntu on a flash drive and externally enlarge the partition, but I'm really afraid with going forward with that plan. Also, despite what I said before, I'd like to avoid re-installing the system if at all possible. Any advice, suggestions or ideas on how to best approach this? Any warnings I should heed? Thanks in advance! update Here's the gparted screenshot - as you can see, there's windows on dual boot (sda1-5 are all related to the windows system), then I have a linux swap, 14GB (so uh... not even 15) of system and 435 of for /home.

  • Sharing an external hard drive in Ubuntu using Samba

    - by cambraca
    /media/MYDISK is where my hard drive is mounted automatically. I created a symlink using: ln -s /media/MYDISK /home/camilo/MYDISK chmod 777 /home/camilo/MYDISK I'm setting up smb.conf like this: [myshare1] comment = external disk browsable = yes path = /home/camilo/MYDISK guest ok = yes read only = no create mask = 0775 Also, in the [global] section I tried adding the following lines: follow symlinks = yes wide links = yes unix extensions = no The problem is that when browsing the shared folder in Windows 7, I get a "\\etc\myshare1 is not accessible" error. When pointing the path to a regular folder it works fine. Also, when I point it directly to /media/MYDISK, it shows the same error. EDIT: to make it more interesting, I have no graphical interface, so I need to touch the config files directly..

  • Direct DB to Web Server connection

    - by Joel Coel
    I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

  • change directory automatically on ssh login

    - by Gareth
    Hi, I'm trying to get ssh to automatically change to a particular directory when I log in. I tried to get that behaviour working using the following directives in ~/.ssh/config: Host example.net LocalCommand "cd web" but whenever I log in, I see the following: /bin/bash: cd web: No such file or directory although though there is definitely a web folder in my home directory. Even using an absolute path gives the same message. To be clear, if I type cd web after logging in I get to the right folder. What am I missing here? EDIT: Different combinations of quotes/absolute paths give different error messages: LocalCommand "cd web" /bin/bash: cd web: No such file or directory LocalCommand cd web /bin/bash: line 0: cd: web: No such file or directory LocalCommand cd /home/gareth/web /bin/bash: line 0: cd: /home/gareth/web: Input/output error This makes me think that the quotes shouldn't be there, and that there's another error happening.

  • Renting linux server just to make backups of my personnal data ?

    - by Matthieu
    Hi all, I would like to be able to backup ALL my computers data on a Linux server. For now, I have a home server, but soon I will be travelling, without home (so no home server). I was thinking of renting a dedicated linux webserver, but this is expensive, and I don't need a fast machine "web-oriented" with mysql server and all, I just need a full SSH access (full control, and then I install my programs). Does "backup servers" exist ? Am I doing it wrong (maybe that is not a good solution) ? Note : I run Mac OS, Windows and Linux, I backup through rsync, I want full control on my backup, not an automated "magic" backup like MobileMe or anything like that. Edit : I need around 500Gb storage

  • Using multiple wifi connections simultaneously on Windows

    - by Salman A
    My office PC has a one wireless network card and there are three available wifi connections: primary, backup and backup of a backup (grin). Is it possible for me to use all three simultaneously. If this results in an increase in bandwidth that's well and good, but primary reason is every now and then one of the network fails and i have to switch back and forth between the available networks by disconnecting, viewing available networks and connecting to next one hoping its running. Do i need more than one network card or a software e.g. a proxy.

  • CentOS: eth0 not starting on boot

    - by Cameron Aziz
    Whenever I reboot a CentOS Hyper-V VM, eth0 does not start automatically. All I need to do is perform ifup eth0 and all is fixed, but that isn't feasible from ssh! I am starting in runlevel 3. After I perform ifup eth0 on the console: [root@localhost ~]# ifconfig eth0 Link encap:Ethernet HWaddr 00:15:5D:2B:2B:07 inet addr:10.10.0.3 Bcast:10.10.0.255 Mask:255.255.255.0 inet6 addr: fe80::215:5dff:fe2b:2b07/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:34 errors:0 dropped:0 overruns:0 frame:0 TX packets:49 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4656 (4.5 KiB) TX bytes:6399 (6.2 KiB) Interrupt:9 Base address:0xa000 [root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 BOOTPROTO=none IPADDR=10.10.0.3 NETMASK=255.255.255.0 GATEWAY=10.10.0.1 USERCTL=no ONBOOT=yes [root@localhost ~]# chkconfig --list | grep network network 0:off 1:off 2:on 3:on 4:on 5:on 6:off

  • Switch user from locked screensaver?

    - by desert69
    I'm having the same problem as this, but the answer from there doesn't work for me. Neither in my iMac upgraded from Lion to Mountain Lion (currently at 10.8), nor from a Mac Mini with Lion Server (10.7.4). I have "Show fast user switching menu as" enabled at "Users & Groups" Login Options, but when I have to login from screensaver, there's no option to switch user. How can I enable such an option? EDIT: I think I forgot to mention that we believe (just guessing) that it has to do with network accounts. We use network accounts here, and have that issue. My boss says he could solve this issue at his house's Mac, which don't use network accounts. Does it make a difference?

  • Fight for your rights as a video gamer.

    - by Chris Williams
    Soon, the U.S. Supreme Court may decide whether to hear a case that could have a lasting impact on computer and video games. The case before the Court involves a law passed by the state of California attempting to criminalize the sale of certain computer and video games. Two previous courts rejected the California law as unconstitutional, but soon the Supreme Court could have the final say. Whatever the Court's ruling, we must be prepared to continue defending our rights now and in the future. To do so, we need a large, powerful movement of gamers to speak with one voice and show that we won't sit back while lawmakers try to score political points by scapegoating video games and treating them differently than books, movies, and music. If the Court decides to hear the case, we're going to need thousands of activists like you who can help defend computer and video games by writing letters to editors, calling into talk radio stations, and educating Americans about our passion for and appreciation of computer and video games. You can help build this movement right now by inviting all your friends and fellow gamers to join the Video Game Voters Network. Use our simple tool to send an email to everyone you know asking them to stand up for gaming rights: http://videogamevoters.org/movement You can also help spread the word through Facebook and Twitter, or you can simply forward this email to everyone you know and ask them to sign up at videogamevoters.org. Time after time, courts continue to reject politicians' efforts to restrict the sale of computer and video games. But that doesn't mean the politicians will stop trying anytime soon -- in fact, it means they're likely to ramp up their efforts even more. To stop them, we must make it clear that gamers will continue to stand up for free speech -- and that the numbers are on our side. Help make sure we're ready and able to keep fighting for our gaming rights. Spread the word about the Video Game Voters Network right now: http://videogamevoters.org/movement Thank you. -- Video Game Voters Network

  • Permission forbidden on localhost with apache2

    - by N Alex
    Here is what I am trying to do. I tried to add another folder to apache and I get the following error when trying to acces testing/index.html. The idea is that I would like to have for every customer a folder like /home/neagoe/Work/InterWebs/Projects/[PROJECT NAME]/CustomerProjects/website/dist. Forbidden You don't have permission to access /index.html on this server. Apache/2.2.22 (Ubuntu) Server at testing Port 80 Here are the steps that I followed: Step1: sudo chmod a+x /home/neagoe/Work/InterWebs/Projects/testing/CustomerProjects/website/dist Step2: sudo chown -R www-data:www-data /home/neagoe/Work/InterWebs/Projects/testing/CustomerProjects/website/dist sudo chmod -R 775 /home/neagoe/Work/InterWebs/Projects/testing/CustomerProjects/website/dist Step3: sudo adduser $USER www-data Step4: sudo a2enmod userdir Step5: sudo cp /etc/apache/sites-available/default /etc/apache/sites-available/testing I edited the file /etc/apache/sites-available/testing so it looks like this: <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName testing DocumentRoot /home/neagoe/Work/InterWebs/Projects/testing/CustomerProjects/website/dist <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /home/neagoe/Work/InterWebs/Projects/testing/CustomerProjects/website/dist/ > Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog ${APACHE_LOG_DIR}/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

All the pages that I found following the same steps as described above. I know there are similar questions here on the internet, but the answer is to change permission to the directory which I did on Step2. I am sorry if this is really a duplicate but I could't find the right answer. Thank you! PS. I asked this also on AskUbuntu but didn't get any answers so I'm trying my luck here.

  • How to enable printer settings over Jetdirect on HP 4100N

    - by zsero
    I have a HP 4100N printer and I am using it over network. Previously I was able to access the printer settings over internet, but now the only thing visible is Device Info and Networking. I can connect to the web server and I can set all the network related settings, but that's not what I want. There should be a supplies, config, print info, etc. page, what are not visible now. Can you tell me what setting should I set to enable this printer config page on the webserver? The printer is a HP 4100N and the network card is J4169A (Jetdirect 610n).

  • Script to recursively grep data from certain files in the directory

    - by Jude
    I am making a simple shell script which will minimize the time I spend in searching all directories under a parent directory and grep some things inside some files. Here's my script. #!/bin/sh MainDir=/var/opt/database/1227-1239/ cd "$MainDir" for dir in $(ls); do grep -i "STAGE,te_start_seq Starting" "$dir"/his_file | tail -1 >> /home/xtee/sst-logs.out if [ -f "$dir"/sysconfig.out]; then grep -A 1 "Drive Model" "$dir"/sysconfig.out | tail -1 >> /home/xtee/sst-logs.out else grep -m 1 "Physical memory size" "$dir"/node0/setupsys.out | tail -1 >> /home/xtee/sst-logs.out fi done The script is supposed to grep the string STAGE,te_start_seq Starting under the file his_file then dump it sst-logs.out which it does. My problem though is the part in the if statement. The script should check the current directory for sysconfig.out, grep drive model and dump it to sst-logs.out if it exists, otherwise, change directory to node0 then grep physical memory size from setupsys.out and dump it to sst-logs.out. My problem is, it seems the if then else statement seems not to work as it doesn`t dump any data at all but if i execute grep manually, i do have data. What is wrong with my shell script? Is there any more efficient way in doing this?

  • Securely automount encrypted drive at user login

    - by Tom Brossman
    An encrypted /home directory gets mounted automatically for me when I log in. I have a second internal hard drive that I've formatted and encrypted with Disk Utility. I want it to be automatically mounted when I login, just like my encrypted /home directory is. How do I do this? There are several very similar questions here, but the answers don't apply to my situation. It might be best to close/merge my question here and edit the second one below, but I think it may have been abandoned (and therefore never to be marked as accepted). This solution isn't a secure method, it circumvents the encryption. This one requires editing fstab, which necessitates entering an additional password at boot. It's not automatic like mounting /home. This question is very similar, but does not apply to an encrypted drive. The solution won't work for my needs. Here is one but it's for NTFS drives, mine is ext4. I can re-format and re-encrypt the second drive if a solution requires this. I've got all the data backed up elsewhere.

  • How to execute files on LAN drives in a Windows Domain

    - by matnagel
    We have a very small LAN here, but some peolpe here think we need Active Directory, though nobody knows how to maintain it. I am not in the position to change this. How can I get full access (on Linux it would be "execute" rights) also for files on network drives (the files are just on another machine next room) My account is in the group Administrators on a windows 2003 server Domain Controller. I cannot open simple MS Access 2000 Databases or CHM Files from network drives in the lan How to do that? Some policy setting? I want to change that once. It is useless. We have no distinction between local or network files here. I would have to copy everything to a local drive and then do what I want.

  • Default gateway is in different subnet. How to configure in RHEL6.2

    - by Dmytro Leonenko
    I have two subnets routed to my server from ISP. I have only one gateway ip. The gateway is on the same VLAN as my IP address. For example netowrk 1 is 1.0.0.0/24 and network 2 is 2.0.0.0/24. Both are routed to eth0 by my ISP. Gateway is 1.0.0.1. My host ip is 2.0.0.1/24 (eth0) So I can configure default gateway manually with ip route add default dev eth0 ip route add default via 1.0.0.1 and then internet connection works properly. How do I configure it in /etc/sysconfig/network-scripts/ifcfg-eth0 ? I tried to set GATEWAY=1.0.0.1 but it doesn't work. Tried to set GATEWAY and GATEWAYDEV in /etc/sysconfig/network and it does only what first command from listing above do.

  • Mikrotik server networks and Cain & Abel

    I'm connected to the internet via a mikrotik server network. Recently, I read about that scaring application named Cain & Abel and all the capabilities it offered for malicious users. I don't know if anyone on my network is using or even aware of such application but my questions are: 1- How to protect myself from this program? 2- How to know if someone using such application against me? 3- Is Tor Bundle capable of protecting me from Cain & Abel? 4- If I filled my e-mail password via SSL page, Can Cain & Abel collect it? 5- Is it safe to use SKYPE or Yahoo Messenger voice chat if some one using Cain & Abel on my network?

  • Two subnets on one switch with no VLAN and possible problems

    - by casey_miller
    As far as I know in order to use two subnets on one physical cable VLAN's are recommended. However, is it possible to achieve this (i.e: two subnets on one physical network) like 192.168.1.0/24 and 10.0.0.0/8 networks. What kind of problems or hidden rocks this way contains? With VLAN's it's possible to better isolate so users wouldn't easly sniff the other network. But in my environment it's okay if user on one subnet could listen to the traffic on another network. Is it the only problem?

  • MAAS/JuJu Clarifications

    - by ectoskeleton
    I really love the concept of MAAS underlying an OpenStack implementation, but there are a few questions about MAAS that I am not entirely clear on. Should all hosts be set to network boot at all times or after they have been registered and allocated as a service, should they boot to disk? After juju bootstrap is executed, I turn on the machine that has been allocated (note WoL isn't working, I suspect it's being blocked on the network), the machine boot's up and then juju status executes correct, agent running and all that good stuff. If I 'reboot' the machine (testing power failure/problem whatever), juju status comes back but the agent-state is no longer in running state, and so far I have to destroy the environment and restart. In all cases I have never been able to deploy any services to any of the other nodes. I deploy the service with juju, note which node it was assigned, and then start the system. The system just boots up into a basic node. If I SSH to it I have to enter password, so it's not setting up the ssh key or anything. This is on Ubuntu 12.04.1 LTS systems and HP GL360G7 hosts. The MAAS management server is running as a VM but all on the same network. At this point I am not sure if I am doing something wrong or if there is a problem somewhere else. Is the idea that anytime a host is rebooted it should be rebuilt from the ground up, or is something else going on behind the scene to tell it to boot the local image. If the latter, why doesn't the agent start on a system that has been successfully setup before (juju bootstrapped system)?

  • File doesn't exist in Linux although it's located in Terminal

    - by Mazen Ayman
    I'm a bit new to unix/linux environment, but I have a small problem. I'm using "locate" to find the path of a file I need, it gives me the path for it, but the file doesn't exist in that path, like that: locate test1.txt /home/user/test files/text1.txt /home/user/test1.txt~ "test files" directory is where I was keeping the file and I copied it to the home directory once but I deleted it, no idea what it keeps telling me there is still a tmp file for it. it worth mentioning that I used the command: locate test1.txt~ |xargs -n1 rm to remove that tmp file, but maybe that what caused the problem. I tried to show hidden files, and check for temp files, didn't find it either. any clue what happened?
