• UNIX-Security Advise

  - by Phoibe

  Hello, I want to build a quite secure UNIX-Server. Mechanisms I already implemented: SNORT + fwsnort for banning psad to block network-scanning attempts Portknocking to start+open SSH (key-based login - no password) hourly update of IP-Tables-Rules from a Security-Subscription Fail2Ban ClamAV & Rootkithunter + Logwatch What service-independent security mechanism would you add to this? What mechanism are you using? The server will run Apache&Postfix. For Apache hiding the server-information ofc. and nothing I can think of for Postfix. Thanks

• How secure is Remote Desktop from Mac OS X to Windows Server 2003?

  - by dwhsix

  It's unclear to me exactly how secure Remote Desktop access from Mac OS X to a Windows Server 2003 machine is. Is the communication encrypted by default? What level of encryption? Are there best practices for making this as secure as possible? I found http://www.mobydisk.com/techres/securing_remote_desktop.html but it's unclear how much of that is still relevant for current versions of RDP and Windows Server. I know I can tunnel RDP over ssh, but is that overkill or redundant?

• Run .sh file in linux machine via putty

  - by Prateek

  I want run an .sh file which take an argument in a Linux machine. I'm using plink.exe to execute this .sh file from a windows machine. But I don't know what to write in the batch file in order to run plink.exe which in turn executes the .sh file and this file arguement. I have written following batch command: @echo off start C:\Users\Prateek\Desktop\PLINK.EXE -ssh -P 22 user@host -pw password sh -x "/home/user/copy.sh" On executing it, I get: + echo '' + echo 'Enter partner id' Enter partner id + read pid : Actually 'Enter partner id' is the argument, which I need to pass.

• gitosis always asks for git password

  - by Cylindric

  I've just followed the simple gitosis install instructions on an Ubuntu server, such as these http://blog.agdunn.net/?p=277 On the server I log in as "mark", and into /home/mark/.ssh/ I copied my keyfiles id_rsa and id_rsa.pub from my laptop. I used that id_rsa.pub when initialising the gitosis stuff, and can happily connect locally when logged in as 'mark'. From my laptop though, where I have the same keys, I can't connect. I just get an error: git clone git@support:gitosis-admin.git Initialized empty Git repository in u:/gitosis-admin/.git fatal: The remote end hung up unexpectedly The server is Ubuntu 9.04, the client is a Win7 laptop with Cygwin and WinSysGit.

• How to connect to WPA2 encrypted wireless-network when booted from CloneZilla Live-CD?

  - by caligula

  My intention is to perform a backup of my laptop's (Dell Vostro 3350) sda1 disk to my desktop. After some googling I decided to use CloneZilla for that purpose. I have an OpenSSH server installed and running on my desktop. So I inserted CloneZilla CD to CD-rom, booted from it, then chose an option smth like "use ssh server to store image". Then I got an invitation to choose a network interface. I chose wlan0 and entered shell to manualy configure connection. And that's where I got into trouble, for wifi-network which I wanted to use is WPA2-encrypted, and I don't know how to connect to it from command line. Can somebody assist me. Appreciation for advance.

• A good Linux alternative to Ubuntu for a working environment.

  - by Roozak

  Hi, Im running a decent laptop with 3GB ram and 2GHz Core Duo. I use it mainly for working which requires several SSH and SFTP connections to servers and running a VM most of the time. Nothing much more intensive than that. I like using Ubuntu 9.10 however I have the issue of Nautilus and the top/bottom menus freezing up on me constantly - dare I say it, alot more problems than when I was using Windows Vista. Im just looking for recommendations of other operating systems which would be suitable for the task. Thanks

• API server not function ["The connection has been reset"]

  - by Miguel Beltrán

  I'm having some troubles with one of my servers. I've done an application with two servers, one the frontend that grabs the data of server API (Ubuntu server). Well, yesterday had a lot of visits and the API server stop functioning but: -I can do stuff in MySQL by SSH. -The memory usage is ok. -The logs are ok. -The bandwitch usage is ok. -If i restart the server or Apache2, function by some time (3-4 minutes). And the most important i think if i tries to access to API (Is rest-style with http) it puts me the Firefox error "The connection has been reset". I'd tried: -Restart the server -Restart Apache2 -Restart MySQL -Viewed the logs of Apache2/MySQL I don't know too much about systems so i don't know what to do more.

• What services does hosts.allow NOT affect?

  - by Jed Daniels

  I know that hosts.allow and host.deny only affect things that are tcpwrappered, but what does this mean in practice? It seems that most people use hosts.allow to handle ssh and nfs blocking, but what other services are typically handled there? And what services AREN'T typically handled there? Edit: ok, I realize I did a terrible job of explaining what I was after. No, I'm not interested in knowing if a particular service can be handled by hosts.allow, I want to know if a service will be handled. For example, if I do an lsof -i, I get a nice list of things that are listening for connections to my box. I want to know which ones will be affected if I go stick an entry into hosts.allow (well, I really want to know which ones won't be affected).

• linux log memory hogging issue

  - by helpmhost

  Hi, We have a VPS server (it's using Virtuozzo). On a few occasions now, our VPS memory was fully used up and no new connections could be made to the server on SSH, SMTP, or POP. The only thing that works is connecting to the web service. Luckily, plesk is running on the VPS and we have been able to reboot it through plesk (as well as see that the RAM is 100% used). I would like to find what process is causing this. I have a feeling it's MySQL, but don't really know. Is there some sort of logging I could implement that would help me find out what was the cause of this next time it happens? Thanks.

• Would it be smarter to setup a Linux development server at home, or to use a hosted server?

  - by markle976

  I am in the process of learning as much as I can about LAMP. I was wondering if I should set a web server on my home network, or use a service like Rackspace (cloud space)? I need to have root access, to be able to access it remotely via SSH/FTP/HTTP, and to be able to install things like subversion, etc. I currently have Comcast so I have plenty of bandwidth, but I am not sure if this would violate the TOS, and/or compromise the security of my home network. Pricing for these cloud hosts, seems reasonable ($11 per month plus about $0.10 per GB of bandwidth), but I am not sure if I will have to control I am looking for.

• Force10 S60 remote management

  - by StaringSkyward

  We've got a Force10 S60 switch to replace an older Cisco. I can't find a way to give the switch itself an IP address on the local VLAN so I can ssh to it. The config guide talks about using either a management interface on a separate management network or dedicating e.g. a gigabit port as a management port with a dedicated IP address. Ideally I would like to do what we do currently with the Cisco switches, which is in effect give the entire switch an IP so it can be reached from any host on the same VLAN without having to use up a physical port on the switch or physically connect the management port to another device. Is this possible with the S60 and if so, how would you give it, say the address 10.0.1.1 in vlan 10 (10.0.1.1/24)? Thanks!!!

• Causes of hard crashes on Windows XP and how to debug

  - by Sam Brightman

  I am occasionally seeing hard lockups on XP: totally unresponsive to keyboard/mouse, screen freezes at time of crash, no SSH/VNC possible. Very intermittent, nothing in the logs. I never see a blue screen on any kind of error message. This morning I logged in via VNC, logged out again, 20 minutes later physically sat at PC and it crashed around the time of VNC logout. I tend to suspect video cards in these kind of situations but it's a modern-ish card with modern drivers (one revision back, but this has been happening for 5 revisions or more) and normally would at least see a blue screen I expect. What would you suspect? Where can I look or what can I set up for more information? Bear in mind that this happens about once every 3 or 4 weeks, so extensive logging or intrusive monitoring isn't really an option.

• interesting uses for a headless host running Ubuntu.

  - by Manuel

  Hey! So, I have configured a pc with no monitor, keyboard or mouse running Ubuntu. I use it as a ssh server, file backup, web server, etc. Though, it seems as if I could use it for sooo much more. The problem is I can't think of many more uses. What interesting uses of a headless host have you heard of? Is there a cool trick you want to share? Thanks! Manuel

• iMac goes black, makes clicking sound... thoughts?

  - by Josh

  This is the second time this has happened. The display on my Apple iMac (20-inch Late 2006) just went black, system was completely unresponsive to mouse/keyboard input, I could not SSH into nor ping the machine, and it didn't show up in ARD. I could hear a fairly loud clicking noise from inside which sounded like the DVD drive trying to seek -- but there is no disc in the drive. It could possibly be the hard drive... I pressed the power button and the system powered off, and now will not power on again. Thoughts / suggestions as to next course of action?

• Input devices stopped working during system upgrade

  - by amorfis

  Hi, I was upgrading Ubuntu on my server (but Ubuntu is in desktop version) when mouse and keyboard stopped working :( So the screen went black (screensaver), and now I can't do anything. I don't know what stage of upgrade it stopped working, probably now it waits for me to answer some question. Keyboard and mouse were connected by KVM, connecting them directly doesn't help. Both are on USB. What I can do, is connecting to the machine by ssh. Can I somehow see and answer questions of update system and somehow finalize process of upgrade?

• How can I secure Postgres for remote access when not in a private network?

  - by orokusaki

  I have a database server on a VMWare VM (Ubuntu 12.04.1 LTS server), and it just occurred to me that the server is accessible via the web, since the same physical server contains a VM that hosts public websites. My iptables in the database are such that only SSH traffic, loopback traffic, and TCP on port 5432 are allowed. I will only allow host access to the Postgres server from the IP of the other VM on the same physical machine. Does this seem sufficient for security, assuming there aren't gaping holes in my general OS configuration, or is Postgres one of those services that should never be web facing, (assuming there are some of "those"). Will I need to use hostssl instead of host in my pg_hba.conf, even though the data will travel only on my own network, presumably?

• Using Vim on the ipad... Any tips?

  - by pax1728

  I'm itching to program on my ipad. With the iSSH app I was able to log on to my university's server and even open an X server window. Unfortunately, the experience within iSSH is still rather clumsy. When using vim, the bottom line is hidden by the keyboard. Does anyone have any experience with SSH connections and the ipad or iphone? Are there better applications to use? I would prefer not to jailbreak my ipad.

• Ubuntu server very slow out of the blue sky (Rails, passenger, nginx)

  - by snitko

  I run Ubuntu server 8.04 on Linode with multiple Rails apps under Passenger + nginx. Today I've noticed it takes quite a lot of time to load a page (5-10 secs). And it's not only websites, ssh seems to be affected too. Having no clue why this may be happening, I started to check different things. I checked how the log files are rotated, I checked if there's enough free disk space and memory. I also checked IO rate, here's the output: $ iostat avg-cpu: %user %nice %system %iowait %steal %idle 0.17 0.00 0.02 0.57 0.16 99.07 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvda 2.25 39.50 16.08 147042 59856 xvdb 0.00 0.05 0.00 192 0 xvdc 2.20 25.93 24.93 96530 92808 xvdd 0.01 0.12 0.00 434 16 xvde 0.04 0.23 0.35 858 1304 xvdf 0.37 0.31 4.12 1162 15352 Rebooting didn't help either. Any ideas where should I be looking?

• Passing all traffic through Cloudflare

  - by Nick

  I am new to Linux System Administration and I am experimenting with iptables trying to learn how to really lock down a system with them. And one thing a friend of mine recommended was that there was a way to pass all incoming traffic through Cloudflare so even if attackers resolved the server ip they still couldn't (D)dos it directly. This is exactly what they said: "Simply config your servers iptables to only allow incoming connections from CloudFlares IP ranges then set it to allow only your IP/IP range to connect on port 21 (SSH)" Could someone help me on what command I'd need to run for Ubuntu to get this effect?

• firehol (firewall) with bridge: how to filter

  - by Leon

  I have two interfaces: eth0 (public address) and lxcbr0 with 10.0.3.1. I have a LXC guest running with ip 10.0.3.10 This is my firehol config: version 5 trusted_ips=`/usr/local/bin/strip_comments /etc/firehol/trusted_ips` trusted_servers=`/usr/local/bin/strip_comments /etc/firehol/trusted_servers` blacklist full `/usr/local/bin/strip_comments /etc/firehol/blacklist` interface lxcbr0 virtual policy return server "dhcp dns" accept router virtual2internet inface lxcbr0 outface eth0 masquerade route all accept interface any world protection strong #Outgoing these protocols are allowed to everywhere client "smtp pop3 dns ntp mysql icmp" accept #These (incoming) services are available to everyone server "http https smtp ftp imap imaps pop3 pop3s passiveftp" accept #Outgoing, these protocols are only allowed to known servers client "http https webcache ftp ssh pyzor razor" accept dst "${trusted_servers}" On my host I can connect only to "trusted servers" on port 80. In my guest I can connect to port 80 on every host. I assumed that firehol would block that. Is there something I can add/change so that my guest(s) inherit the rules of the eth0 interface?

• FreeNX 0.7.3 under CentOS 6.3 - Negotiating link parameters

  - by Frank

  since some days I try to get freenx (CentOS package 0.7.3) running under CentOS 6.3. It is like found on many websites: First login is successfull, after that all login attempts fail with the negotiation error. A simple ssh with the same username to the server is successful. For the installation I followed the howTo on http://wiki.centos.org/HowTos/FreeNX Strange is that the changelog of FreeNX 0.7.3 tells that this bug was fixed. Has anybody been successful in running FreeNX under CentOS without this problem and knows how to fix it? Frank

• Hostname problems in CentOS 5.5

  - by spoon16

  I just set up a CentOS 5.5 machine on my local network and attempted to modify the hostname by editing /etc/sysconfig/network file. When I'm logged in locally the change to the hostname is reflected and seems to be working fine. When I open a SSH session via PuTTY from Windows this is what I see at the prompt: [root@? ~]# cat /etc/sysconfig/network NETWORKING=yes NETWORKING_IPV6=yes HOSTNAME=mini.local [root@? ~]# sysctl kernel.hostname kernel.hostname = ? [root@? ~]# hostname ? [root@? ~]# hostname -f hostname: Unknown server error A couple of other symptoms that may be helpful in troubleshooting this problem. I can ping the CentOS box from my Windows machine via IP but not hostname. Also, my Netgear router does not display the hostname when I view the "Connected Devices", I do see the mac address and the proper IP listed though. How can I make it so that the hostname is properly propagated throughout my network?

• Running game server and webserver on EC2

  - by mazzzzz

  Hey guys, I have a webhost, and an EC2 server (to run a game server on). The problem is that I want to access/modify the EC2's files with php admin programs. I looked into a lot of options to just have the webhost communicate with the EC2 server (ssh, etc), but none of them panned out. My question is if I were to install a lightweight webserver (think lighttpd) on my EC2 server, how badly would it hurt the game server's performance? I was leaning away from this solution, even though the webserver (on the EC2 server) wouldn't get many hits (less than a 100 a day). Thanks for your thoughts, Max
