  • network issue ubuntu 8.04 in vmware esx

    - by hoberion
    ok, this is really pissing me off I have one ubuntu 8.04 instance running on vmware (esx) which decided after a reboot to stop resolving dns requests, I also cant connect to it using ssh although I can ping the server and its really that server (when I shutdown the server the ping also stops) stuff I tried: - reboot again :) - nslookup - serverip - setting networking to dhcp - offering some cute kittens to lucifer - removing the virtual nic and adding another (to get a different mac) - migrating the instance to another esx host - drinking 20 cups of espresso - stopped all services - running dnsmasq on another server and connecting to that dns - tcpdumping - disabling ip6 symptoms: cant resolve anything nslookup just says "no servers found..." although I can ping the servers traceroute to gateway doesnt work (even with traceroute -4 -n gatewayip) collegues laughing at me any thoughts

  • IPFW not locking people out

    - by Cole
    I've had some brute-forcing of my ssh connection recently, so I got fail2ban to hopefully prevent that. I set it up, and started testing it out by giving wrong passwords on my computer. (I have physical access to the server if I need to unblock myself) However, it never stops me from entering passwords. I see in /var/log/fail2ban.log that fail2ban kicked in and banned me, and there's a ipfw entry for my IP, but I'm not locked out. I've changed the configuration around, and then tried just using the ipfw command myself, but nothing seems to lock me out. I've tried the following blocks: 65300 deny tcp from 10.0.1.30 to any in 65400 deny ip from 10.0.1.30 to any 65500 deny tcp from 10.0.1.30 to any My firewall setup has a "allow ip from any to any" rule after these though, maybe that's the problem? I'm using Mac OS 10.6 (stock ipfw, it doesn't seem to have a --version flag) Thanks in advance.

  • screen resume works on top of VPN

    - by michael
    I connect to my network using VPN. I have screen running and 'ssh' to a server. I then kill my shell and I was able to 'resume' by 'screen -r'. This works as expect. But when I disconnect VPN and re-connect VPN, and type 'screen -r' again. I was not able to get my last screen again. And I see "Write failed: Connection reset by peer46.11 MiB | 642 KiB/s" in the screen. Can you please tell me if it possible to reconnect 'screen' if my VPN is disconnect. Thank you.

  • rsync set group owner, group permission

    - by ChrisInEdmonton
    I want to use rsync to transfer files from my computer to a remote Linux system. Regardless of the local file's group ownership, I want to set these values on the remote side. If I was on the remote Linux system, I could create the directory and set the ownership and permissions as: mkdir my_directory chown :my_group my_directory chmod 775 my_directory If I create the directory locally and then use rsync (remember, I don't have my_group locally), I do: rsync -ae ssh --chmod=ug+rw,Dug+rwx my_directory remoteserver:dest That works, but I cannot figure out how to set the group owner through rsync. If I do a chmod g+s dest, my_directory has the correct group owner but all of the files inside have the incorrect group owner.

  • VM can’t connect to outside in bridged mode

    - by Kamal
    Hi Guys, I am not able to ping any machine(not even the host) from Guest VM in bridged mode. But I got an IP which is on the same subnet as host. I can ping my guest VM from the host and can use ssh to connect to the guest. I am using Vmware workstation 6.5. Guest VM is a centos VM and host is windows xp. Every thing works fine in NAT mode. Any clues as to what could be happening. I tried disabling all the firewalls I have. My virtual network editor shows that my ethernet adapter(the one my host uses) is used for bridging. It is connected. I don't understand how I can get an IP address from DHCP server. I can't ping any of the DNS servers in generated /etc/resolv.conf which are the same as that of my host

  • I don't understand how GDM is starting...

    - by tladuke
    I'm on Karmic. I had no keyboard, so I enabled autologin and some other stuff over ssh to get x2x going. Now I can't find what I did. I'm trying to just start X and XBMC now. I don't need gnome. I disabled gdm: sudo update-rc.d -f gdm remove but it still somehow manages to start on boot. Where can I look around for what I did? If I stop gdm then startx again, it goes straight to XBMC like I want.

  • centos: nginx + thin webserver, incoming connections not allowed

    - by cbrulak
    I setup a fresh CentOS 5 install, compile nginx from scratch and am using thin as the rails server. If I visit the ip adress on the LAN: (for example) 1.2.3.4 I get the website not found error. However, I can ssh into the machine. If I use links to visit the ip address, I get the landing page. Any suggestions? Thanks EDIT I ran system-config-securitylevel and then was able to change the security settings to allow incoming connections.

  • How do I create /Groups/ folder in Mac OS X

    - by fettereddingoskidney
    I am familiar with adding Groups with the GUI in MAC OS X, but I am trying to do it via SSH to a computer I remotely manage as a production server. I want to create / modify some of my users for a particular directory by creating a new group. In Another helpful serverfault post, I see that I need to add the users to the group name at /Groups/foo, however my system's Groups folder does not exist... Does Mac OS X create the Groups directory only when you actually create the group – if there do not already exist any groups on the Machine? Is this something that I can do simply using: mkdir "Groups" Or maybe I'm wrong altogether. Any pointers for how to go about this with Unix? – I should note also that this group will be used to manage the access to a directory on my server via an .htaccess file. Thanks!

How to pull changes from others to main repo?

  • Rails 3.0.3 and Polyglot Gem problem

    - by user557417
    Hello all. I hope you can help me. I had a rails app running locally, and also uploaded and running on Heroku. All was well. Last week, I started work again and ran into a snag. At the beginning of my day, I opened up Terminal and ran 'rails s' to start the local server.

  • Sun Grid Engine: Automatically Terminating Idle Interactive Jobs

    - by dmcer
    We're considering using Sun Grid Engine on a small compute cluster. Right now, the current set up is pretty crude and just involves having people ssh to an open machine to run their jobs. We'd like to allow interactive jobs, since that should ease the transition from manually starting jobs to starting them using qsub. But, there is some concern that, if we do, people might accidentally leave their interactive sessions idle and block other jobs from being run on the machines. The issue isn't just theoretical, since we previously tried using OpenPBS and there was a problem with people opening up an interactive job in a screen session and essentially camping on a machine. Is there anyway to configure SGE to automatically kill idle interactive jobs? It looks like this was requested as an enhancement (Issue #:2447) way back in 2007. But, it doesn't seem like the request ever got implemented.

  • PPTP network for server backend LAN?

    - by Sebastian Hoitz
    Here is our problem: We have several webservers, which should be reached from public. The database servers that store the data for the web apps on those webservers though shall not have a public IP. So, since I want to be able to connect to the SQL servers using ssh for example, and those servers need to talk with each other, I had this idea: Internet | ------------------ | | Webserver 1 Webserver 2 Database Server | | | -------------- vLAN -------------- | PPTP | Workstation (my PC) My idea was that I can connect to the vLAN using PPTP so that I have access to all servers in that LAN, but the database server remains unvisible to the public. Is this infrastructure a good idea?

  • Why does Amazon release private keys instead of public keys?

    - by S37H
    My brain is wrapped around the axle on public and private keys. When you create a cloud server (instance) on Amazon's EC2 service and then want to connect to it via SSH, Amazon requires you to download private a key to make the connection. Doesn't the idea behind public/private key suggest that Amazon should be require you to download a public one? Further, if I set up an SFTP server for a customer to use, should I be installing their key on the server or giving them a key from the server? In either case, should it be a public or private key?

  • Monitor LSI 3ware raid controller on ESXi

    - by aseq
    This concerns a server that runs ESXi (v. 4.x or 5.x) installed on drives that are configured into a raid10 using an LSI 3ware 97050 raid controller. I would like to know if there is a way to monitor the LSI 3ware series of controllers, in particular the 9750, through ESXi. And to hopefully also run the monitoring daemon LSI provides. I know you can set up a cronjob to execute tw_cli through ssh on the ESXi server. However that's not really ideal. I am not using vcenter by the way. It would be nice to have more than just monitoring working, since the 3ware software has a very useful web client, besides tw_cli.

  • Stack , data and address space limits on an Ubuntu server

    - by PaulDaviesC
    I am running an Ubuntu server which has around 5000 users. The users are allowed to SSH in to the system. So in order to cap the memory used up by a process I have capped the address space limits using limits.conf. So my question is , should I be limiting the data and stack ? I feel that is not required since I am capping address space. Are there any pitfalls if I do not cap the stack and data limits?

  • fatal: http://myserverip/home/git/example.git/info/refs not found: did you run git update-server-i

    - by bobobobo
    I followed this example to set up a git repository on my server. It worked, and I successfully pushed my code to it. But now, how do I pull or clone? Using the docs, I tried git clone http://REMOTE_SERVER/home/git/example.git .. But for me, I'm getting: fatal: http://myserverip/home/git/example.git/info/refs not found: did you run git update-server-info on the server? I ran git-update-server info, but nothing changed Edit: Ah, hold on. I changed it to git clone ssh://REMOTE_SERVER/home/git/example.git and I'm getting something.. it wants my user/pass, but how do I make the server public then not requiring login?

  • Linux wget, how to display progress percentage after session has reload?

    - by skyrail
    I am running debian Squeeze in console mode on a plug computer. I control it opening an SSH session from a Windows machine, on the same local network. I started downloading a large file using wget. What I get is a console progress bar showing the percentage of data downloaded, file size, and download rate. When I close the session, debian is still running and downloading. Fine. But When I close and reopen a session, how can see which amount of data was downloaded, using a linux command ? thanks.

  • Suggest methods for testing changes to "pam.d/common-*" files

    - by Jamie
    How do I test the changes to the pam.d configuration files: Do I need to restart the PAM service to test the changes? Should I go through every service listed in the /etc/pam.d/ directory? I'm about to make changes to the pam.d/common-* files in an effort to put an Ubuntu box into an active directory controlled network. I'm just learning what to do, so I'm preparing the configuration in a VM, which I plan to deploy in metal in the coming week. It is a clean install of Ubuntu 10.04 Beta 2 server, so other than SSH daemon, all other services are stock.

  • "type" Command Not Working As Expected on Git Bash

    - by trysis
    The type command, in Linux, returns the location, on the filesystem, of the given file, if it is in the current folder or the $PATH. This functionality is also available through Windows with the Git Bash command line program. The command also returns a file's location given the file without its extension (.exe, .vbs, etc.) However, I have run into what seems like a strange corner case where the file exists on the $PATH but doesn't get returned using the command. I am thinking of buying a new computer soon, so I looked up the method of transferring the license key from one computer to another, in preparation for actually doing this. The method I found mentioned the files slmgr.vbs and slui.exe, both of which reside in the C:/Windows\System32 folder, which is in my $PATH, as usual for a Windows computer. However, these two files aren't showing up when I use the type command. Also, neither gets executed when I call the files as commands without their extensions in Git Bash, and only slmgr.vbs gets executed when I call them with the extensions. Finally, slmgr.vbs is shown when listing the folder's contents in Git Bash, as well, but slui.exe isn't. I thought this might have to do with permissions, and, indeed, both files have very restrictive permissions, as you can see in the pictures below, but they both have the same permissions, which wouldn't explain why one gets executed and the other doesn't when called directly, nor why one file is listed on command line but the other isn't. C:\Windows\System32 folder, proving the files exist: File permissions for the Users and Administrators groups for the two files (they are identical): And the folder: type command and its output in Git Bash for the 2 files, plus listing the files in the folder (using grep to filter as the folder is huge), as well as listing part of the $PATH (keep in mind, for all these, that Git Bash changes the paths as they are displayed): Sean@MYPC ~ $ type -a slmgr sh.exe": type: slmgr: not found Sean@MYPC ~ $ type -a slmgr.vbs sh.exe": type: slmgr.vbs: not found Sean@MYPC ~ $ type -a slui sh.exe": type: slui: not found Sean@MYPC ~ $ type -a slui.exe sh.exe": type: slui.exe: not found Sean@MYPC ~ $ slmgr sh.exe": slmgr: command not found Sean@MYPC ~ $ slmgr.vbs /c/WINDOWS/system32/slmgr.vbs: line 2: syntax error near unexpected token `(' /c/WINDOWS/system32/slmgr.vbs: line 2: `' Copyright (c) Microsoft Corporation.

My question was that I tried to give my password to scp via piping echo mypassword | scp [email protected]:project/* ~/project/ However it still asks me to manually input the password. How should I specify mypassword to scp in commands? I still don't understand one of the replies. what is a input stream by TTY, for example? What are the common ways for a input stream? How to know what type of input stream a stdin input to a command is? For example that of ssh/scp.

  • Network traffic is not being forwarded from a VM to the network using a bridged interface with Xen + libvirt

    - by foob
    I'm having trouble getting network access from a VM that I'm running using Xen and libvirt. I've been trying different things and reading similar posts online for a couple of days but I'm really stuck at this point. If anybody could offer some insight it would be much appreciated. I have a VM that I'm running on a host with a bridge set up as br0 and an interface eth0 on a 192.168.60.0/24 subnet. The networking portion of the libvirt configuration xml is: <interface type='bridge'> <mac address='ff:a0:d1:e5:07:de'/> <source bridge='br0'/> <script path='/etc/xen/scripts/vif-bridge'/> <model type='virtio' /> </interface> When I start the VM a vif6.0 interface is created on the host and the ifconfig output is: br0 Link encap:Ethernet HWaddr 00:A0:D1:C3:07:DE inet addr:192.168.60.33 Bcast:192.168.60.255 Mask:255.255.255.0 inet6 addr: fe80::2a0:d1ff:fee5:7de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:13 errors:0 dropped:0 overruns:0 frame:0 TX packets:40 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3570 (3.4 KiB) TX bytes:3508 (3.4 KiB) eth0 Link encap:Ethernet HWaddr 00:A0:D1:C3:07:DE inet6 addr: fe80::2a0:d1ff:fee5:7de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:492 (492.0 b) Interrupt:19 Memory:fe8f0000-fe900000 vif6.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:80 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:500 RX bytes:6660 (6.5 KiB) TX bytes:468 (468.0 b) virbr0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.122.1 Bcast:192.168.122.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 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) The 'brctl show' output seems to show the bridge being configured correctly: br0 8000.00a0d1e507de no eth0 vif6.0 The ifcfg-eth0 contents in the VM are: DEVICE=eth0 BOOTPROTO=static HWADDR=FF:A0:D1:E5:07:DE IPADDR=192.168.60.133 NETMASK=255.255.255.0 ONBOOT=yes and the output of ifconfig in the VM look like what I would expect: eth0 Link encap:Ethernet HWaddr FF:A0:D1:E5:07:DE inet addr:192.168.60.133 Bcast:192.168.60.255 Mask:255.255.255.0 inet6 addr: fe80::fda0:d1ff:fee5:7de/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:80 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:468 (468.0 b) TX bytes:7780 (7.5 KiB) but when I try to ssh or ping another computer I get 'no route to host.' Using tcpdump on the host system I tried to see if I could narrow down where the problem is: # tcpdump -vv -i vif6.0 tcpdump: WARNING: vif6.0: no IPv4 address assigned tcpdump: listening on vif6.0, link-type EN10MB (Ethernet), capture size 96 bytes 14:49:40.833997 arp who-has 192.168.60.35 tell 192.168.60.133 14:49:41.833314 arp who-has 192.168.60.35 tell 192.168.60.133 14:49:42.833309 arp who-has 192.168.60.35 tell 192.168.60.133 So the VM is sending out out an arp who-has packet when I try to ssh to 192.168.60.35. I think that this means the setup within the VM is ok and that this is an issue on the host system. If I run tcpdump with the interface of br0 then I don't see these arp packets. My thought here is that the packets are being blocked before going on to the bridge somehow. I tried adding an iptables rule to resolve this: -A FORWARD -m physdev --physdev-is-bridged -j ACCEPT but it didn't work. I also tried the following: /sbin/sysctl -w net.bridge.bridge-nf-call-ip6tables=0 /sbin/sysctl -w net.bridge.bridge-nf-call-iptables=0 /sbin/sysctl -w net.bridge.bridge-nf-call-arptables=0 /sbin/sysctl -w net.ipv4.ip_forward=1 which had no impact. Is it obvious to somebody who has more experience than me what I'm missing here? Should vif6.0 have the same MAC address is eth0 in the vm? Do I need more rules in my iptables? Thanks for any help!

  • Issues with Rsync on a NAS

    - by Daniel Fischer
    I'm trying to rsync a few external hard drives over to my new Nas DS412+ but I'm noticing it's stupid slow. I'm trying it via mounting the backup folder via afb on a Mac. I was told this may be the wrong way to do it. I recently just turned on "network backup" on the Synology and am now running rsync over ssh like: rsync -ar --progress . admin@localip:/backup/path Is this the right way to do it now? Will it be faster? Is there something else I can do to make it faster? Edit: I'm getting a ton of: "failed to set permissions" "failed to set times" now that I run it. What do I do?

  • Create Vmware image from exisiting Ubuntu installation

    - by Tathagata
    I have been stuck on a netbook since last year due to budget constraints, but finally managed to get a decent laptop from a very generous person. Now my ubuntu installation in the netbook has all my development tools, libraries, personal mediawiki, other servers and things that I'm only reminded when the command line complains. I can always ssh into my netbook, but don't want to carry both the computers all the time. Is it possible to create an image from my netbook Ubuntu and use it out of the box in a Vmware player in the new laptop?
