  • How to connect to the guest console via SSH without being admin on host?

    - by Sorin Sbarnea
    How can someone connect to a VM console via SSH, without being an admin on VM-host. This means that you should be able to see the guest boot screen and grub menu in a ssh session. That's important because in some cases you may need to fix the VM without having access to the VM-host admin console. Mainly this is about how you can have your own VM-guest which you can fully control but without having access to VM-host.

  • How to use sudo with WinSCP and ProFTPd?

    - by Gaia
    I need to run the SFTP fileserver binary as root, but direct root login is not allowed. In WinSCP, if I use "default" on SFTP server protocol option everything works as expected. Following the instructions to sudo in WinSCP, I tried using "sudo /usr/sbin/proftpd" (works on the command line without any prompts) but it brings up "Cannot initialize SFTP protocol.

  • Node.js on via DynDNS

    - by Azincourt
    I have never used Node.js but since I am developing a browsergame that needs (almost) "realtime" communication, I am planning on using Node.js for this. To get started, I wanted to use a home server (normal computer) that is conntected to a dynamic IP via DynDNS. Are there the disadvantages using such a setting? What is the best way in combination with Node.js to store game status for a online game session?

  • Accessing a persistent ssh tunnel

    - by woowaa
    How do I pass commands (shell) to a persistent SSH tunnel rather than open a connection for every instance? I have a Python scraper running on a client server which passes URL variables and shell commands to a remote host via a reverse tunnel (forwarded port), so that the URL's are then executed on the host (python fabric ssh localhost:12345 'browser open URL'). I could make the reverse tunnel persistent but how do I echo the url/command to the session? Update - ControlMaster (built into SSH) solves this one.

  • Need help w/ rsync

    - by user71106
    I need some help getting my rync command syntax working. I need to clone the /home/user/public_html folder on a remote server to the server I am logged into via SSH, copying the folder into the same exact path on this local machine. I have root on the local machine I'm in session on and a user account shell on the remote machine. I'm not clear on where to put the SSH login info and how to define the folder paths.

  • Multiple ServerRoot directives in single apache

    - by fip
    i came across a apache httpd 2.2 configuration recently in which multiple ServerRoot-directives were defined, each followed by individual prefork Settings. Sort of like this: ServerRoot root1 <IfModule prefork.c> StartServers 5 MinSpareServers 5 MaxSpareServers 10 MaxClients 150 MaxRequestsPerChild 0 </IfModule> [vhost-configs] ServerRoot root2 <IfModule prefork.c> StartServers 10 MinSpareServers 10 MaxSpareServers 20 MaxClients 250 MaxRequestsPerChild 0 </IfModule> [vhost-configs] In my understanding these are global settings one overriding the other. But is that true and is it still true with the second ServerRoot directive between the prefork blocks? Thank you in advance EDIT They are not in different conditional blocks and both server roots are used in that way that files with relative paths to both are correctly included. I just wondered if a <ServerRoot> would initiate a new scope in which all global statements would not override the configuration of previous ones.

  • Rsync problem...filenames

    - by Jay White
    I'm trying to back up users Chrome Sessions with Rsync with the following command: rsync -e "ssh -i new.key" -r --verbose -tz --stats --progress --delete \ '/cygdrive/c/Users/jay/AppData/Local/Google/Chrome/User Data/Default/Current Session' \ user@host:"/chrome sessions/" Except this doesn't work exactly, as I get a file called chrome in a sessions directory that is already present on the server. Why is this?

  • Can't configure PAM + LDAP on Debian Lenny - Getting error=49 on server logs

    - by Jorge Suárez de Lis
    I've been migrating some servers and desktops using Ubuntu 10.04 from getting the users from an old OpenLDAP implementation to a newer Centos Active Directory. I haven't had any problems so far, until I reached a Debian Lenny server. I've set up the server as the others, setting /etc/ldap.conf and /etc/ldap/ldap.conf. However, when I issue "getent passwd", I get nothing from the LDAP server. Reading the pam_ldap manpage, I realized that /etc/ldap.conf was not an accepted file by pam_ldap -it worked with Ubuntu though-, so I renamed it to /etc/pam_ldap.conf. Same result. However, once I've changed the name of this file, when I login using SSH I get this on the LDAP server logs: [20/Jul/2012:11:19:40 +0200] conn=16501 fd=155 slot=155 connection from x.x.x.50 to 10.1.176.237 [20/Jul/2012:11:19:40 +0200] conn=16501 op=0 BIND dn="uid=ubuntu,ou=Applications,ou=CITIUS,dc=inv,dc=usc,dc=es" method=128 version=3 [20/Jul/2012:11:19:40 +0200] conn=16501 op=0 RESULT err=0 tag=97 nentries=0 etime=0 dn="uid=ubuntu,ou=applications,ou=citius,dc=inv,dc=usc,dc=es" [20/Jul/2012:11:19:40 +0200] conn=16501 op=1 SRCH base="ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es" scope=2 filter="(uid=jorge.suarez)" attrs=ALL [20/Jul/2012:11:19:40 +0200] conn=16501 op=1 RESULT err=0 tag=101 nentries=1 etime=0 notes=U [20/Jul/2012:11:19:40 +0200] conn=16501 op=2 BIND dn="uid=jorge.suarez,ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es" method=128 version=3 [20/Jul/2012:11:19:40 +0200] conn=16501 op=2 RESULT err=49 tag=97 nentries=0 etime=0 The password isn't working. I don't know that could be wrong, anything else seems to be OK. That user/password is working from another clients: [20/Jul/2012:11:29:39 +0200] conn=16528 fd=188 slot=188 connection from x.x.x.224 to 10.1.176.237 [20/Jul/2012:11:29:39 +0200] conn=16528 op=0 BIND dn="uid=ubuntu,ou=Applications,ou=CITIUS,dc=inv,dc=usc,dc=es" method=128 version=3 [20/Jul/2012:11:29:39 +0200] conn=16528 op=0 RESULT err=0 tag=97 nentries=0 etime=0 dn="uid=ubuntu,ou=applications,ou=citius,dc=inv,dc=usc,dc=es" [20/Jul/2012:11:29:39 +0200] conn=16528 op=1 SRCH base="ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es" scope=2 filter="(uid=jorge.suarez)" attrs=ALL [20/Jul/2012:11:29:39 +0200] conn=16528 op=1 RESULT err=0 tag=101 nentries=1 etime=0 notes=U [20/Jul/2012:11:29:39 +0200] conn=16528 op=2 BIND dn="uid=jorge.suarez,ou=People,ou=CITIUS,dc=inv,dc=usc,dc=es" method=128 version=3 [20/Jul/2012:11:29:39 +0200] conn=16528 op=2 RESULT err=0 tag=97 nentries=0 etime=0 dn="uid=jorge.suarez,ou=people,ou=citius,dc=inv,dc=usc,dc=es" I'm using SSHA for storing passwords on the LDAP server. Maybe this is not supported by Debian Lenny? On pam_ldap.conf, I've set up this, as in all the other servers: # Do not hash the password at all; presume # the directory server will do it, if # necessary. This is the default. pam_password md5 Also tried clear, but it didn't work. Anyways, it's weird that issuing getent passwd still gets me no users. However, if I use pamtest from the package libpam-dotfile to test login, it works. # pamtest ssh jorge.suarez Trying to authenticate <jorge.suarez> for service <ssh>. Password: Authentication successful. # pamtest foo jorge.suarez Trying to authenticate <jorge.suarez> for service <foo>. Password: Authentication successful. But "su" won't work also: # su jorge.suarez Id. descoñecido: jorge.suarez Just the output from getent passwd : # getent passwd root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/bin/sh bin:x:2:2:bin:/bin:/bin/sh sys:x:3:3:sys:/dev:/bin/sh sync:x:4:65534:sync:/bin:/bin/sync games:x:5:60:games:/usr/games:/bin/sh man:x:6:12:man:/var/cache/man:/bin/sh lp:x:7:7:lp:/var/spool/lpd:/bin/sh mail:x:8:8:mail:/var/mail:/bin/sh news:x:9:9:news:/var/spool/news:/bin/sh uucp:x:10:10:uucp:/var/spool/uucp:/bin/sh proxy:x:13:13:proxy:/bin:/bin/sh www-data:x:33:33:www-data:/var/www:/bin/sh backup:x:34:34:backup:/var/backups:/bin/sh list:x:38:38:Mailing List Manager:/var/list:/bin/sh irc:x:39:39:ircd:/var/run/ircd:/bin/sh gnats:x:41:41:Gnats Bug-Reporting System (admin):/var/lib/gnats:/bin/sh nobody:x:65534:65534:nobody:/nonexistent:/bin/sh libuuid:x:100:101::/var/lib/libuuid:/bin/sh Debian-exim:x:101:103::/var/spool/exim4:/bin/false statd:x:102:65534::/var/lib/nfs:/bin/false sshd:x:104:65534::/var/run/sshd:/usr/sbin/nologin luser:x:1000:1000:Usuario local de Burdeos,,,:/home/luser:/bin/bash messagebus:x:105:107::/var/run/dbus:/bin/false sge-admin:x:1001:1001:Administrador do SGE,,,:/home/cluster/sge-admin:/bin/bash ntp:x:107:110::/home/ntp:/bin/false haldaemon:x:108:111:Hardware abstraction layer,,,:/var/run/hald:/bin/false vde2-net:x:109:114::/var/run/vde2:/bin/false uml-net:x:110:115::/home/uml-net:/bin/false polkituser:x:111:116:PolicyKit,,,:/var/run/PolicyKit:/bin/false Debian-pxe:x:113:65534:Dummy user for Debian pxe package,,,:/home/Debian-pxe:/bin/false Nscd was stopped from the beginning.

  • Bandwidth sizing for simultaneous RDP sessions

    - by Gareth Marlow
    We're doing some DR scenario planning which will require up to 150 users to RDP into their desktop machines (mainly running Windows XP) over our VPN. We have a 2mbit uncontended internet connection at the moment but there's scope to upgrade this and also to use a secondary SDSL line to give us more bandwidth. Typical bandwidth figures I've seen suggest to plan for 64kbps per session, which works out to 9.6mbps in total. I'd like to know: Does anyone have any real-world data which would support these estimates? Are there any operational 'gotcha's that we need to be aware of? Thanks!

  • Assigning security groups different ranges

    - by Mustafa Ismail Mustafa
    Is it possible to assign a security group in windows 2008 a specific DHCP scope? Meaning, let's say we have 2 groups, employees and managers in the superscope Company. Assuming that each user is distinctly in either group and there are no overlaps, would it be possible to assign members of the security group employees a dhcp address in the range 192.168.1.0/24 and managers 192.168.2.0/24 ? The DHCP server is the same server. This is on Windows SBS 2008 if it makes any difference If it is possible, how do you go about setting it up. TIA

  • Logging in as the same user multiple times in Remote Desktop Windows Server 2008

    - by Little_Johnn
    Quick question: I have a situation where I need to let multiple people on different PCs log into one server 2008 machine as administrator simultaneously over remote desktop. I have the CALs for it, it's just not set up correctly. When one user tries to log in, it boots the other out. What I need is to present to them a different session, just each as logged in as admin. Sorry for the slightly rambling post, I'm new here. Thanks!

  • Configuring Apache for multiple clients

    - by Chris_K
    Last week I had a question here about suexec / suphp but I tried to accomplish too much. I'm going to narrow the scope a bit and try again. I'd like to configure a LAMP server to host multiple clients. I'd like it to seem (from the client's viewpoint) just like any other shared hosting environment. Web sites in their home directory, no need to muck around with file ownerships to get pages served, etc. It would seem that a configuration that involves suexec and suphp is the way to go(?) I'm specifically looking for a current/modern guide on how to accomplish this (I'll be using CentOS if it matters) and I'm afraid I need more than a link to Apache docs. Are there any good How-To's out there? The few I've found have been pretty out of date, but it is quite possible my search was weak.

  • SBS 2008 - Add user not seeing AD users (reconnecting or creating new mailbox)

    - by Robert
    Using SBS 2008 - completely updated. I was originally trying to create a spam mailbox for quarantine purposes, and when I bring up the "select an existing user" it does not display any of the domain users (other than QB database user accounts installed on their server). I have tried changing the scope and still nothing. Searching reveals nothing either. Then later I noticed that we had (1) disconnected mailbox, and I tried to reconnect it to the AD user - and I got the same results. Help would be much appreciated.

  • SharePoint 2010 Search - not search additional content sources

    - by Chris W
    I've got SP 2010 crawling a secondary intranet system that we'll run in parallel as part of a long running migration to SharePoint when it releases. Whilst it's crawling the pages without problem I can't see how to get the results to appear as part of the Quick Search results if the user does a search from the little search dialog box on the home page. Searches completed within a My Sites pages lists results from port the SharePoint installation and the external content source. Searches from the main search dialog only list results of SharePoint items. I tried adding the drop down option to select the site to search but this list only includes the name of the current site and doesn't offer an 'All Sites' scope option which I think would include the content. What am I doing wrong?
