  • script to su with password in script without root

    - by Triplell89
    I have scripted a process that involves updating symbolic links on files located on 3 different machines. On those machines exists 4 users each, who each need to have these links updated. Using su, is there a way to pass the password argument to the command on a single line, without invoking sudo as the users will not have admin rights? My only alternative solution at this point is to ssh around, however I would like to be able to do this without hardcoding in a bunch of hosts/ips.

  • Which is the correct way to config the $TERM and tmux?

    - by bliof
    I am using gnome-terminal with bash. When I set xterm-256color for $TERM and in .tmux.conf most of the things work but when I try to change the colorscheme of vim the things mess up. When I set screen-256color for $TERM and in .tmux.conf the colors work ok but most of the keys go mad. I've tried some of the suggestions from the last link but when I ssh the arrows crash even on the command line.. So how to configure tmux?

  • prevent cpanel/whm from automatically updating php

    - by j w
    I'd like to be sure that cpanel/WHM is definitely NOT going to automatically update my PHP to 5.3 (it will cause all sorts of errors for legacy code). So, please let me know where I should look (either in WHM control panel or via SSH) in order to satisfy myself that PHP definitely won't get upgraded to 5.3 without my say-so?

  • iptables - Allowing Established Sessions?

    - by Sandro Dzneladze
    I'm learning how to use iptables on ubuntu server. Can you please explain to me what "Allowing Established Sessions" means and why should I include it in rules? sudo iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT I understand concept of allowing specific ports and blocking others sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT block all sudo iptables -A INPUT -j DROP But I don't get the concept of allowing established session. Thanks. S.

  • Redirect all outgoing traffic on port 80 to a different IP on the same server

    - by Spacedust
    I have multiple IP addresses on the same server and I would like to redirect all outgoing traffic on port 80 to a different IP on the same server just no to use always main IP. Currently I'm using this: /sbin/iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source IP; and it works well, but it redirects everything and when I make backups over SSH backup it's failing. System: CentOS 5.8 64-bit

  • Windows Server 2008 R2 Firewall - Interface specific rules

    - by Mehmet Ergut
    I'm trying to define per interface rules, much like it was in Server 2003. We will be replacing our old 2003 server with a new 2008 R2 server. The server runs IIS and SQL Server. It's a dedicated server at the hosting company. We use a OpenVPN connection from the office to access SQL server, RDesktop, FTP and other administrative services. Only http and ssh is listening on the public interface. On the old server running 2003, I was able to define global rules for http and ssh, and allow other services only on the vpn interface. I can't find a way to do the same on 2008 R2. I understand that there is the Network Location Awareness service, firewall rules are applied according to the current network location. But I don't understand the purpose of this on a server. The only close solution I found is to set the scope on the firewall rule and restrict remote ip addresses to the private subnet of the office. But the ports will still be listening on the public interface. So how can I restrict a firewall rule to the connections coming from the vpn interface ? A note on this page states that scoping a rule to an interface does not exist anymore: In earlier versions of Windows, many of these command accepted a parameter called interface. This parameter is not supported in the firewall context in Windows Vista or later versions of Windows. I can't believe that they simply decided to remove a core firewall functionality that every firewall has. There must be a way to restrict a rule to an interface. Any ideas ? I'm still unable to find an adequate solution to my problem. So for now, my workaround is this: Administrative services listen on VPN IP address Firewall rules restrict the scope to the local IP address of VPN Public services listen on all interfaces, no scope restriction on firewall rules This is not optimal, if I change the IP address of the VPN, I need to edit the firewall rules too. It won't be the case if the rules were bound to the interface.

  • Redirect all traffic to specified hosts behind NAT

    - by biesiad
    Is there a possibility to redirect all traffic to specified hosts behind NAT? For example i have a server, a domain "mydomain.com" and 3 hosts behind NAT. I wish to configure 3 subdomains: host1.mydomain.com host2.mydomain.com host2.mydomain.com and each of them to redirect all ports to specified host in local net. That redirection should provide funcionality like this: http://host1.mydomain.com (can be achieved using apache) ssh [email protected] (???) and other protocols on diferent ports Thanks for any help.

  • Easy way to deploy PHP sites from git

    - by Leopd
    I'm looking for recommendations on how to automate / simplify deployment from a git repository (github) to a hosting service. The hosting service supports FTP (yuck) / SSH / SFTP access. Any good tools out there to give push-button deployment of new revisions? I know it's not a hard script to write, but when you start thinking about things like roll-back and multiple sites, it gets complicated enough that I'd rather not re-invent the wheel.

  • isa 2006 blocks outgoing traffic with no rule specified

    - by codesnik
    I've created a rule near the top, allowing all outgoing traffic from "All Users" from specified IP range to external network. However, connections are blocked sometimes for no apparent reason. For example, one attempt to ssh to an external server would fail, and another immediatelly after that - won't. to the same server! logging shows thoose failed connections as denied, but "rule" column is blank. any suggestions?

  • Security: Managing network shares remotely on Ubuntu?

    - by Industrial
    Hi everyone, I am about to setup a home network server running Ubuntu Server and I'm currently a bit worried about how to handle network shares and permissions in a good way. After working a bit lately with Netgears ReadyNAS's units, I have become really spoiled with how easy it was to set up network shares and giving a specific user different levels of network access to a specific share (forbidden access, read, read/write). How would I accomplish the same with my Ubuntu server through SSH? Thanks a lot

  • slow interactive response time

    - by ndhert
    VMWare ESXi4 with 2 VM's (FreeBSD-amd64). When doing a reboot on one of the VM's, the reboot is done in normal speed, but after that, the interactive response time on the other gets very slow: pressing return at the command prompt, takes serveral seconds to be exectuted. SSH-ing to the VM machine takes a long time before you are logged in. Only after 20 minutes or so, the situation is normalized. What's the reason and how to remedy?
