• Simple one-way synchronisation of user password list between servers

  - by Renaud Bompuis

  Using a RedHat-derivative distro (CentOS), I'd like to keep the list of regular users (UID over 500), and group (and shadow files) pushed to a backup server. The sync is only one-way, from the main server to the backup server. I don't really want to have to deal with LDAP or NIS. All I need is a simple script that can be run nightly to keep the backup server updated. The main server can SSH into the backup system. Any suggestion? Edit: Thanks for the suggestions so far but I think I didn't make myself clear enough. I'm only looking at synchronising normal users whose UID is on or above 500. System/service users (with UID below 500) may be different on both system. So you can't just sync the whole files I'm afraid.

• IP Blacklists and suspicious inbound and outbound traffic

  - by Pantelis Sopasakis

  I administer a web server and recently we had our IP banned (!) from our host after they received a notification e-mail for abuse. In particular our server is allegedly involved in spam attacks over HTTP. The content of the abuse report email we received was not much informative - for example the IP addresses our server is supposed to have attacked against are not included - so I started a wireshark session checking for suspicious traffic over TCP/HTTP while trying to locate possible security holes on the system. (Let me note that the machine runs a Debian OS). Here is an example of such a request... Source: 89.74.188.233 Destination: 12.34.56.78 // my ip Protocol: HTTP Info: GET 'http://www.media.apniworld.com/image.php?type=hv' HTTP/1.0 I manually blacklisted this host (as well as some other ones) blocking them with iptables, but I can't keep on doing manually all day long... I'm looking for an automated way to block such IPs based on: Statistical analysis, pattern recognition or other AI-based analysis (Though, I'm reluctant to trust such a solution, if exists) Public blacklists Using DNSBL I actually found out that 89.74.188.233 is blacklisted. However other IPs which are strongly suspicious like 93.199.112.126 (i.e. http://www.pornstarnetwork.com/account/signin), unfortunately were not blacklisted! What I would like to do is to automatically connect my firewall with DNSBL (or some other blacklist database) and block all traffic towards blacklisted IPs or somehow have my local blacklist automatically updated.

• *nix OS that is easy to update to latest software

  - by rjstelling

  I need to configure a server (*nix) that runs our (bespoke) CMS and Applications. In the past I have defaulted to using Cent OS 5, but I find this outdated difficult to upgrade the software to the versions we require. For example, we need PHP 5.3, but CentOS 5 has 5.2. Updating is fine but breaks something else (normally MySQL support in PHP). Eventually it will get to a situation where I can't upgrade because of missing dependancies and incompatible versions. Error: Missing Dependency: httpd = 2.2.3-43.el5.centos.3 is needed by package httpd-devel-2.2.3-43.el5.centos.3.i386 (updates) Is there a better alternative OS for hassle free updates, I need: Apache 2.2.17 (the development version for apxs) MySQL 5.5.8 PHP 5.3.5

• cannot print from flash-player plugin

  - by eleven81

  I am running flash-player plug-in 10.0.32.10 inside of Firefox on a SLED 11 machine. Firefox can print to the network printer without issue from File Print. However, I cannot get the flash-player plugin to print at all. The print dialog comes up, asks for which printer, and which pages. I click Print and it was as if I had pressed cancel. Is this a known issue?

• Should I be worry about max number of files in a folder in *NIX filesystems?

  - by ??????

  In a social networking project we want to store user's avatars in a folder. I think in one year or two it'll reach to 140K (I've seen this issue before and it will be around this number). I want to spread files in folders. If a folder contains 1000 files then create another folder and do store files from 1001 to 2000. Is this a good approach or I'm just very cautious about the issue? (File system : EXT3)

• Maximizing TCP connections on HAProxy load balancer

  - by imaginative

  I am currently using HAProxy in order to load balance tcp connections from clients to my Erlang app server. The connection is persistent, which means I'm limited to roughly 64K clients on an optimized server (I'm currently running HAProxy on an m1.large EC2 instance). My app server is designed to horizontally scale based on the number of TCP connections. What's worrying me though is I'll need an equal number of HAProxy servers as app servers since it's a 1:1 connection. Is there currently a way to "proxy" the tcp connection to the app server so that once HAProxy sends the client off to my Erlang server, it can free up the connection, ready to serve another client? Are there any papers, existing solutions out there I can read so that I only have to worry about the 64K limit on my app servers, and not on the load balancing servers themselves?

• Ubuntu 9.10 X Stuck in restart loop - I think...

  - by widgisoft

  Trying out Ubuntu, installation went fine - upgraded to the proprietary nVidia drivers but on restart I get a login prompt and the screen is flashing really fast almost as if Xserver is trying to start and failing, I can type when the screen isn't in a "flash" as it were and it's so fast and random it's hard to even type a login name without it missing some characters - this makes typing a password (i.e. not being able to see which characters made it or not) very hard. I can log back into the live cd and alter my settings - but I can't even find out how to stop X stop starting on boot; Looks like they've moved everything around :-p I'd like to: Stop X from crashing and going insane (if it is actually Xserver) Know how to stop X from starting on bootup, Looks like interactive boot is also off by default now Update: A temporary work around seems to be enabling ssh and just connecting to the box over the network - ssh seems to work fine :-p Cheers, Chris

• How to make ssh/rsync/etc use a VLAN network interface?

  - by Annan

  A company I work for has a number of virtual servers with ElasticHosts. They are setup in such a way that eth1 is on a private VLAN connecting them to each other. This is so backups sent between servers are not charged at the same rate as external data transfer. My understanding of how VLANs and network interfaces work is sketchy at best. How can I make ssh, rsync, etc. transfer data through the VLAN? My final solution: I spent a while trying to figure this out, For all servers involved, edit /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static ONBOOT=yes HWADDR=YOUR_MAC_ADDR IPADDR=192.168.0.100 NETMASK=255.255.255.0 Where HWADDR should already be set and the last octate of IPADDR should be different from each other. Then run, on all servers /etc/init.d/network restart After this the IP addresses specified by IPADDR can be used directly as any other IP address.

• Owner of uploads directory is `www-data` but this prevents FTP access via PHP scripts

  - by letseatfood

  To allow write access to Apache, I needed to chown www-data:www-data /var/www/mysite/uploads to my site's upload folder. This allows me to delete files from the folder via unlink() in a PHP script. Unfortunately, this prevents another PHP script, which uses FTP functions, from working. I think it is because the FTP user is mike and now that the uploads directory is owned by www-data, mike cannot access it. I added mike to the group www-data, but this does not fix the issue. Can somebody advise me on how to allow PHP FTP functions to work in addition to file deletion using PHP's unlink() function?

• How hard for a Software Developer to Maintain a Server

  - by Samy

  I'm a software developer and don't have much experience as a sysadmin. I developed a web app and was considering buying a server and hosting the web app on it. Is this a huge undertaking for a web developer? What's the level of difficulty of maintaining a server and keeping up with the latest security patches and all that kind of fun stuff. I'm a single user, and not planning to sell the service to others. Can someone also recommend an OS for my case, and maybe some good learning resources that's concise and not too overwhelming.

• How restore back up email files in qmail

  - by Maysam

  I have problem with restoring some old backup mail files in a mail server that uses qmail. The problem is, when I copy a new email file to the /cur directory, the number of emails in front of inbox increases, but when I click on the inbox, I don't see the newly copied email. I can only see the old emails. I also deleted maildirsize and courierimapuiddb files and they where automatically created again, but it didn't help and I cannot still see the email in my inbox. Is there something I am missing? How can I restore the backed up email files? Please note that when I copy the email files in /.sent-mail/cur directory, they are all displayed in my sent box, but that doesn't happen for inbox files in /cur directory.

• Multiple interfaces to one IP address?

  - by Delan Azabani

  At present, I have: a Netgear router with DHCP off at 192.168.0.1 my computer eth0 at 192.168.0.2 wlan0 at 192.168.0.2 The wlan0 interface always connects to the router, while the eth0 interface connects to other computers with crossover and acts as a dnsmasq DHCP server for network boot and installation. If I use the Gnome NetworkManager to enable both connections, that is, with wlan0 connected to the router/internet and eth0 to another computer, both as 192.168.0.2, I cannot access the internet while eth0 is connected. Why is this? How can I configure my computer to follow wlan0 for Internet usage, but use eth0 for itself (the latter is working but blocking wlan0).

• Get an object by its objectGUID using ldapsearch

  - by orsogufo

  If I have the objectGUID attribute as returned by the ldapsearch command, how can I search the whole directory for an object with that objectGUID? For example, if I search a user getting its objectGUID, I get the following: ldapsearch -x -D $MyDn -W -h $Host -b "dc=x,dc=y" "(mail=something)" objectGUID # 7f435ae312a0d8197605, p, Externals, x.y dn: CN=7f435ae312a0d8197605,OU=p,DC=x,DC=y objectGUID:: b+bSezFkKkWDmbIZiyE5rg== Starting from the value b+bSezFkKkWDmbIZiyE5rg==, how can I create a query string to get that object?

• SELinux adding new allowed samba type to access httpd_sys_content_t?

  - by Josh

  allow samba_share_t httpd_sys_content_t {read execute getattr setattr write}; allow smbd_t httpd_sys_content_t {read execute getattr setattr write}; I am taking a stab in the dark with resources I've looked at, at various places that the above policies are what I want. I basically want to allow Samba to write to my web docs without giving it free access to the operating system. I read a post by a NSA rep saying the best way was defining a new type and allowing both samba and httpd access. Setting the content to public content (public_content_rw_t) does not work without making use of some unrestrictive booleans. To state this in short, how do I allow samba to access a new type?

• A decent S3 bucket manager for Ubuntu

  - by Luke

  I'm looking for a decent S3 bucket manager for Ubuntu (Gnome). I prefer it to integrate with Nautilus so it will look like just any other drive (a la WebDAV) but so far I haven't been able to find anything that I'd like to use on a daily basis. What bucket managers do you use for Ubuntu or what bucket manager would you recommend? UPDATE: S3FS seems to be what I'd really want to use since it lets me integrate my buckets directly into my file-system. However, when trying S3FS I do not get the impression that it's ready for prime time. I'm stunned by the fact that there are no decent bucket managers out there for Ubuntu/Gnome, guess I have to build it myself...

• ps aux as non-root doesn't show all processes

  - by JMW

  hi, i'm using an ubuntu 10.04 server... when i run ps aux as root i see all processes when i run ps aux as nonroot i see JUST the processes of the current user after a bit of research i found the following solution: root@m85:~# ls -al /proc/ total 4 dr-xr-xr-x 122 root root 0 2010-12-23 14:08 . drwxr-xr-x 22 root root 4096 2010-12-23 13:30 .. dr-x------ 6 root root 0 2010-12-23 14:08 1 dr-x------ 6 root root 0 2010-12-23 14:08 10 dr-x------ 6 root root 0 2010-12-23 14:08 1212 dr-x------ 6 root root 0 2010-12-23 14:08 1227 dr-x------ 6 root root 0 2010-12-23 14:08 1242 dr-x------ 6 zabbix zabbix 0 2010-12-24 23:52 12747 [...] my first idea was, that it got mounted in a weird way: /etc/fstab is ok and it doesn't seem to be mounted in an weird way... my second idea was, that there might be a rootkit: but it's not a rootkit... rkhunter tells me, that there is no rootkit installed... i don't know if it is since the machine got installed or came with an update. i've just installed zabbix-agent on the machine and realized, that it didn't work properly... What could have caused such strange permissions (500) and how can i set it back to an normal level (555) ? Crazy, i've never seen something like that... thanks in advance for any help and merry christmas :) see you

• How to execute a shell script on startup?

  - by vijay.shad

  I have create a script to start a server(my first question). Now I want it to run on the system boot and start the defined server. What should I do to get this done? My findings tell me put this file in /etc/init.d location and it will execute when the system will boot. But I am not able to understand how the first argument on the startup will be start? Is this predefined somewhere to use start as $1? If I want to have a case startall that will start all the servers in the script, then what are the options I can manage. My Script is like this: #!/bin/bash case "$1" in start) start ;; stop) stop ;; restart) $0 stop $0 start ;; *) echo "usage: $0 (start|stop|restart)" ;; esac

• Sensitive data in init scripts

  - by Steve Jorgensen

  I'm adapting some examples I've found by Googling to build an init script to run a VirtualBox OSE virtual machine as a daemon. I would like to specify a password for VNC access to the VM, and this must be given as an argument to the VBoxHeadless command. Conventionally, init scripts are readable by standard users, and this seems like a useful convention, but I also don't want the VNC password for this VM to be stored in easily accessible plain text. What's the most appropriate/conventional way to handle this kind of situation? Maybe put a root-readable supporting data file someplace, and have the init script load the value from there?

• SSH Advanced Logging

  I've installed OpenSUSE on my server and want to set ssh to log every command, which is send to system over it. I've found this in my sshd_config: # Logging # obsoletes QuietMode and FascistLogging #SyslogFacility AUTH #LogLevel INFO I guess that both of those directives has to be uncommented, but I'd like to log every command, not only authorization (login/logout via SSH). I just want to know, if someone breaks into my system, what did he do.

• Kerberos: Running an app with a parameter using krenew

  - by Mihai Todor

  I need to run an application with krenew, but the application also needs to receive a parameter via command line and I need to send its output to a file. From the documentation, it looks like this should do the trick: krenew -t -- sh -c 'compute-job > /afs/local/data/output' but, unfortunately, when I run the command below: krenew -s -- sh -c './my_app config.xml > results/test.txt &' the application just dies after a while and I can see from the output of ps aux that krenew is not running along with my_app. I am not sure what the parameter -t does, and as far as I can see, if I run krenew -s ./my_app, it works properly. I hope someone can clarify this.
