• Linux VLAN Bridge

  - by raspi

  I have home network with VLANs, one for LAN, one for WLAN and one for internet. I'd like to use bridging so that instead of configuring these same VLANs to every machine, they had own VLAN ID and bridges were LAN, WLAN and internet. I've tried it but for some reason keep-alive/ttl seems to get broken because SSH sessions etc suddenly disconnects. We have this same setup working in workplace for 4+ years with 100+ customers but it's custom firewall/router hardware so accessing it is impossible. I know that it runs Linux. So what is Debian/Ubuntu default network settings doing wrong or is it just NIC driver/hw problem? I've tried to mess araund with ttl etc settings without any luck. The bad stuff is happening in the bridge because current VLAN-only setup works fine. interfaces: auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 allow-hotplug eth1 iface eth0 inet static iface eth1 inet static auto vlan111 auto vlan222 auto vlan333 auto vlan444 auto br0 auto br1 auto br2 # LAN iface vlan111 inet static vlan_raw_device eth0 # WLAN iface vlan222 inet static vlan_raw_device eth0 # ADSL Modem iface vlan333 inet static vlan_raw_device eth1 # Internet iface vlan444 inet static vlan_raw_device eth0 # LAN bridge iface br0 inet static address 192.168.0.1 netmask 255.255.255.0 bridge_ports eth0.111 bridge_stp on # Internet bridge iface br1 inet static address x.x.x.x netmask x.x.x.x gateway x.x.x.x bridge_ports eth1.333 eth0.444 bridge_stp on post-up iptables -t nat -A POSTROUTING -o br1 -j MASQUERADE pre-down iptables -t nat -D POSTROUTING -o br1 -j MASQUERADE # WLAN bridge iface br2 inet static address 192.168.1.1 netmask 255.255.255.0 bridge_ports eth0.222 bridge_stp on Sysctl: net.ipv4.conf.default.forwarding=1

• Automated Linux VMs on Hyper-V 2012

  - by Mick

  I have a requirement to create a ton of linux VMs for our customers (we run managed infrastructure) on Hyper-V 2012 in the coming months and I have an issue with automating it. Here is how I need it to work: User accesses their web page and creates a VM. VM is created with a unique IP and name User logs in over SSH I know Hyper-V quite well and can work with powershell and am a C# programmer so the development side of things is taken care of. I also know enough about Linux to be at least competent: I have used it on and off for a number of years but not done anything Enterprise-level with it. All this can be done easily by manual processes but I need to be able to script or program this to automate it as there could be hundreds of them being created but I don't know how. My first thought is to have a database with random-generated names and IPs already created but I don't know how to get a Linux VM to boot up and grab one from the database... I suppose a Kickstart script would take care of it but I don't know what to do from there. Here is what is bouncing around in my head: Create a std linux build. - Easy to do Someone clicks "Create VM" and I pull a name and IP from the database and write it to a kickstart script. - Easy to do I could then open the template VHDX file and copy in the script and then save it. - Not sure if possible User boots up new VM and the kickstart script gives it the name and IP I assigned it. My problem is that I don't know how to open a VHDX file and insert a kickstart script into it... can't figure it out. I am reaching here and this solution may be miles off... I am more used to creating Windows VMs with scripts and so on which i am more familiar with... any help would be appreciated. Thanks Mick

• Is there any way to force my Linux box to always boot up with a self-assigned IP address?

  - by Jeremy Friesner

  This is perhaps an unusual request: I'm trying to get a Debian Linux box to always give itself a self-assigned IP address (i.e. 169.254.x.y) on boot. In particular, I want it to do that even when there is a DHCP server present on the LAN. That is, it should not request an IP address from the DHCP server. From what I can see in the "man interfaces" text, there is an option for "manual", and an option for "dhcp". Manual assignment won't do, since I need multiple boxes to work on the same LAN without requiring any manual configuration... and "dhcp" does what I want, but only if there is no DHCP server on the LAN. (A requirement is that the functionality of these boxes should not be affected by the presence or absence of a DHCP server). Is there a trick that I can use to get this behavior? EDIT: By "no manual configuration", I mean that I should be able to take this box (headless) to any LAN anywhere, plug in the Ethernet cable, and have it do its thing. I shouldn't have to ssh to the box and edit files to get it working each time it is moved to a different LAN.

• Hosting a server for websites, ftp and random use at home?

  - by Zolomon

  I'm wondering what's the best option for me if I want to move all my hosted websites (from a hosting company) to a server at my own home? Basically, the needs I have are: be able to host websites using PHP/ASP.NET (haven't really decided yet - both would be preferred!) enable FTP so I can create accounts for my family members to access the server for file handling SSH SSL - for secure connections (this is something you have to buy/apply for per domain, not sure if there are any server side settings that have to be made) be able to stream video remote desktop host home-brew applications that can run as services use either MySQl/SQLite/SQL for relational database storage What should I think of before I buy a server? What hardware will I need, what will limit my server? I basically want to learn networking better as I'm a software and web developer but haven't had the resources to acquire any serious toys until now. At the time of writing, most of my websites have 60 visits/day so I don't suspect them to be very demanding. Is there something I haven't thought of that I should have? What OS would you suggest I run? FreeBSD vs Windows Server vs ?

• Subdocument in Word won't save

  - by ChrisW

  Because I know Word has a history of not liking very large documents (my supervisor specifically told me not to use LaTeX... grr), I decided to learn the Master document / subdocument feature of Word when writing my PhD thesis. I have the title page / table of contents etc in the master document, and each chapter as a separate document. However, when I save the master document, it appears to save all the chapter documents apart from one (Chapter 4), for which it brings up the Save Document dialog box, helpfully with "Chapter4.docx" in the "Save as" box (n.b. Chpater4.dox is not open). Clicking save does nothing, and doesn't make the dialog box go away. Saving as a different document means that my changes aren't reflected in the same document. There must be some reason Word doesn't like this particular document but I've got no idea why - there's nothing special in it that isn't in any of the other chapters. I have tried closing all documents, renaming Chapter4.docx, opening the master document, expanding all documents, OKing the warning that Chapter4.dox does not exist, and inserting the 'new' document, but even when I save the master document it still won't save the new Chapter4 document. If anyone knows any reason why Word is acting like this (or if I'm doing anything stupid), I'll be eternally grateful (p.s. sorry for the long rambling message. It's late; I've been working on my PhD 4.5 years, I really really want to throw this computer out the window, and I hope people are kind enough not to downvote this question because of it's rambling nature!) Update With Word closed, I've tried to delete Chapter4.docx (having made a backup!) - but I get a warning that it can't be deleted because it's open in Microsoft Word... these files are on a network drive and the same problems are happening on 2 different computers. I could login to the filestore through ssh and force the file to be deleted, but I'm curious to know why this is happening!

• RTNETLINK answers: File exists... maybe because assigned a new mac adress

  - by steven

  I got a "RTNETLINK answers: File exists Failed to bring up eth0:1" on "ifup eth0:1". I suspect it happens because i assigned a new mac adress in my VM's network adapter. Can you tell me how to fix the issue? My configuration looks like this: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.1.80 netmask 255.255.255.0 gateway 192.168.1.1 dns-nameservers 192.168.1.1 # Alias being connected to 192.168.10.x Network auto eth0:1 allow-hotplug eth0:1 iface eth0:1 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 Why do I get "RTNETLINK answer: File exists.." suddenly? I worked with this configuration before without problems. All i did in the past is to renew the adapters mac adress. At the moment I am connected to the 192.168.10.x Network and if I do /etc/init.d/networking stop /etc/init.d/networking start then i got "RTNETLINK [...] falied to bring up eth0:1" but the strage thing is that i am able to connect to 192.168.10.83 via ssh from my host machine. But I cannot reach the internet from the debian client. I hope it is clear what my problem is, now. update if i change my /etc/network/interfaces like this then "ifup eth0" fails, too with the same error! # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 allow-hotplug eth0 iface eth0 inet static address 192.168.10.83 netmask 255.255.255.0 gateway 192.168.10.10 dns-nameservers 192.168.10.1 with verbose option enabled i got: Configuring interfache eth0=eth0 (inet) run-parts --verbose /etc/network/if-pre-up.d ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0 RTNETLINK answers: File exists Failed to bring up eth0. same if i type this manually: ip addr add 192.168.10.83/255.255.255.0 broadcast 192.168.10.255 dev eth0 label eth0

• Dedicated virtual setup is slow with WordPress

  - by kovshenin

  Hey. I'm running a Fedora linux server on the Amazon EC2 platform. I'm pretty sure there's something wrong with my configuration as it seems to be very slow. SSH sometimes takes over 30 seconds to connect, a WordPress generated web page could take 5 seconds to load, and it could take 20 seconds to load, which is pretty awkward. MySQL queries are all executed in less than a second, so I don't think that's the case. I'm not really sure where the issue lies, but a simple page written in PHP loads instantly. A fresh WordPress installation starts lagging. Same works perfect on grid hosting at MediaTemple for instance, so I'm pretty sure I missed something. If you could please direct me to the right tools and articles which would help me out. Thanks so much! Fedora Core 8, php 5.2.6, MySQL 5.0.45, OpenSSH 4.7p1, OpenSSL 0.9.8b. PHP is configured as a module to Apache 2.2.9, all websites based on virtual hosts. I have some on-going php scripts running from time to time in the background via cron. Thanks.

• Transparent proxying leaves sockets with SYN_RCVD in MacOS X 10.6 Snow Leopard (and maybe FreeBSD)

  - by apenwarr

  I'm trying to create a transparent proxy on my MacOS machine in order to port the sshuttle ssh-based transproxy VPN from Linux. I think I almost have it working, but sadly, almost is not 100%. Short version is this. In one window, start something that listens on port 12300: $ while :; do nc -l 12300; done Now enable proxying: # sysctl -w net.inet.ip.forwarding=1 # sysctl -w net.inet.ip.fw.enable=1 # ipfw add 1000 fwd 127.0.0.1,12300 log tcp from any to any And now test it out: $ telnet localhost 9999 # any port number will do # this works; type stuff and you'll see it in the nc window $ telnet google.com 80 # any host/port will do # this *doesn't* work! After the latter experiment, I see lines like this in netstat: $ netstat -tn | grep ^tcp4 tcp4 0 0 66.249.91.104.80 192.168.1.130.61072 SYN_RCVD tcp4 0 0 192.168.1.130.61072 66.249.91.104.80 SYN_SENT The second socket belongs to my telnet program; the first is more suspicious. SYN_RCVD implies that my SYN packet was correctly captured by the firewall and taken in by the kernel, but apparently the SYNACK was never sent back to telnet, because it's still in SYN_SENT. On the other hand, if I kill the nc server, I get this: $ telnet google.com 80 Trying 66.249.81.104... telnet: connect to address 66.249.81.104: Connection refused telnet: Unable to connect to remote host ...which is as expected: my proxy server isn't running, so ipfw redirects my connection to port 12300, which has nobody listening on it, ie. connection refused. My uname says this: $ uname -a Darwin mean.local 10.2.0 Darwin Kernel Version 10.2.0: Tue Nov 3 10:37:10 PST 2009; root:xnu-1486.2.11~1/RELEASE_I386 i386 Does anybody see any different results? (I'm especially interested in Snow Leopard vs Leopard results, as there seem to be some internet rumours that transproxy is broken in Snow Leopard version) Any advice for how to fix?

• Setting up squid proxy server to in turn connect using another proxy server [closed]

  - by AnkurVj

  My institute uses the Squid proxy server and authentication mechanism requires username and password to be entered. This means that, I can log in on only one machine at a time and Internet access for me is restricted to that machine. I sometimes require Internet access on multiple machines simultaneously. What previosuly worked for me was the following : On one of my own machines A, I set up a Squid proxy server that allowed all local machines without any username and password. I configured rest of the machines to use this machine A as the proxy server. On machine A I logged into the institute proxy server using my browser. This way, I could access Internet from all my machines, by effectively channeling my requests through the server A. Recently, I lost that machine and configuration and now I tried to set it up again in the same manner. However, I cant seem to remember exactly how I made it work. I keep getting Connection Refused (111) on other machines. My guess is that my squid server isnt able to forward requests from other machines to the actual squid server. I could use any help for debugging this problem. I don't want to use alternatives such as ssh tunneling. This solution has worked for me in the past, I just don't remember how to set it up the same way again.

• ESXi 5 VM Putty session hangs, vSphere client timing out

  - by user192702

  First of all I believe this is a ESXi issue but let me know if you have seen this. It started about a year ago when I noticed occasionally when I putty via SSH to my VM guests, if I do anything that makes it to display a lot of things at once, the session will hang and I have to start a new one quite often only to find the same behaviour. What I meant by display a lot of things can be any of the following: 1) tail -f filename 2) Paste a long command 3) less filename If I type in one character at a time this won't happen. I tried searching online and it always point me to flow control settings and the various suggestions I've tried have never been able to resolve the issue. Since last week, I've noticed I'm not able to connect to my POP3 server from Outlook (it's timing out from Outlook's perspective). Today I tried to connect to the ESXi via vSphere client and it gives me a time out also. Exact behavior and error I saw is similar to the one posted at the following URL but the suggested technique also failed to resolve the issue. http://davidcocke.blogspot.hk/2012/02/unable-to-login-with-vsphere-client.html Has anyone experienced this before? Any suggestions on how to troubleshoot this?

• Execute remote shell commands on windows XP embedded

  - by BartD

  The following situation: We have Windows XP Embedded clients that have all admin shares disabled and only have read-only shares (for security reasons). What we want to do is run remote shell (dos) commands on these machines. At first we looked at PsExec & BeyondExec applications (and all sorts of variants), but all of them rely on having at least an admin$ share, which are disabled on our systems. Telnet is not secure enough, as is RSHD servers. So we looked at the next obvious solution: and SSH server. We also prefer an open-source or freeware solution that is still maintained. I looked at freeSSH server for Windows, but that didn't run stable, I tried installing copSSH, WinSSH & openSSH for Windows, but none of these applications seem to work on Windows XP Embedded. The services can either not be installed or cannot be started. I don't know why. Some kind of dependency that is missing. So are there any other solutions out there? I don't care about having to an agent installation locally of some kind on each system, as long as the size of the software is small enough. Can someone suggest some alternatives to what I've already mentioned? Thank you very much.

• How do I change the Dropbox directory on a headless GNU/Linux server?

  - by DrTwox

  I have installed Dropbox 2.0.0 via command line on my home server (Ubuntu Server 12.04) to use for off-site automated backups, but I can't change the directory that the Dropbox daemon keeps synced. I've tried the following: The official docs say to use the desktop application, which is not applicable in my situation. However I installed the desktop app on my desktop machine and changed the default folder location, but I can't find where this change is stored in the ~/.dropbox/ directory so I can make the same change on the server. This page (and several others) recommends a Python script to do the job. Looking at the script, it opens a SQLite database called ~/.dropbox/dropbox.db, which does not exist on my Dropbox install, leading me to believe the script is out-of-date. This forum thread suggests manually inserting the required row in the config.db database, which I did, but it made no difference. I checked the same database file on my desktop machine, and it does not have the dropbox_path key, so I'm presuming the information in that thread is also out of date for version 2.0. I have tried to launch the Dropbox GUI configuration wizard over SSH with X11 forwarding, as suggested in one of the answers, but the binary must detect the absence of a local X11 install and it starts a command line daemon instead, which provides no means to change the option I need. I am currently using a symlink, as suggested as an answer, but this is a kludge. I would like to know the correct way to make the change. How do I change the Dropbox directory on a headless GNU/Linux server? Update: I've ditched Dropbox and started using Copy. Their Linux tools and support is far superior to Dropbox. I leave this question here in case someone, someday, can answer it.

• Which isn't working on linode servers (Ubuntu 10.04)?

  - by chrisjlee

  Currently trying to configure a linode server running on ubuntu 10.04. I utilized a stackscript (Default drupal profile) which seemed to run successfully. The log indicate so as well. Then ssh'd into the server (as root) to try to configure php. When i run a which php, which php5 they both return nothing. A which python returns something though. I know where the default path to php but i usually just like to use it as confirmation that php exists. Do i have to modify some configurations to enable which to work? Also tab completion doesn't seem to work for when i apt-get install? Update: Thanks for the suggestions guys.

• Is there a way to prevent password expiration when user has no password?

  - by Eric DANNIELOU

  Okay, we all care about security so users should change their passwords on a regular basis (who said passwords are like underwear?). On redhat and centos (5.x and 6.x), it's possible to make every real user password expires after 45 days, and warn them 7 days before. /etc/shadow entry then looks like : testuser:$6$m8VQ7BWU$b3UBovxC5b9p2UxLxyT0QKKgG1RoOHoap2CV7HviDJ03AUvcFTqB.yiV4Dn7Rj6LgCBsJ1.obQpaLVCx5.Sx90:15588:1:45:7::: It works very well and most users often change their passwords. Some users find it convenient not to use any password but ssh public key (and I'd like to encourage them). Then after 45 days they can't log in as they forgot their password and are asked to change it. Is there a way to prevent password expiration if and only if password is disabled? Setting testuser:!!:15588:1:45:7::: in /etc/shadow did not work : testuser is asked to change his password after 45 days. Of course, setting back password expiration to 99999 days works but : It requires extra work. Security auditors might not be happy. Is there a system wide parameter that would prompt the user to change expired password only if he really has one ?

• Heartbeat/DRBD failover didn't work as expected. How do I make the failover more robust?

  - by Quinn Murphy

  I had a scenario where a DRBD-heartbeat set up had a failed node but did not failover. What happened was the primary node had locked up, but didn't go down directly (it was inaccessible via ssh or with the nfs mount, but it could be pinged). The desired behavior would have been to detect this and failover to the secondary node, but it appears that since the primary didn't go full down (there is a dedicated network connection from server to server), heartbeat's detection mechanism didn't pick up on that and therefore didn't failover. Has anyone seen this? Is there something that I need to configure to have more robust cluster failover? DRBD seems to otherwise work fine (had to resync when I rebooted the old primary), but without good failover, it's use is limited. heartbeat 3.0.4 drbd84 RHEL 6.1 We are not using Pacemaker nfs03 is the primary server in this setup, and nfs01 is the secondary. ha.cf # Hearbeat Logging logfacility daemon udpport 694 ucast eth0 192.168.10.47 ucast eth0 192.168.10.42 # Cluster members node nfs01.openair.com node nfs03.openair.com # Hearbeat communication timing. # Sets the triggers and pulse time for swapping over. keepalive 1 warntime 10 deadtime 30 initdead 120 #fail back automatically auto_failback on and here is the haresources file: nfs03.openair.com IPaddr::192.168.10.50/255.255.255.0/eth0 drbddisk::data Filesystem::/dev/drbd0::/data::ext4 nfs nfslock

• Linux/hostapd: AP can ping clients, clients can access internet, can't access www@wlan1 with more than 5-6 packets at once

  - by mhambra

  Please edit the title, can't make it sound better. -- OP. Hi all, I have a Wifi USB dongle in a PC, that serves as an AP for laptop. wlan1: 192.168.2.1, netmask 255.255.255.0, routed: route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.2.1 ping 192.168.2.2 (laptop): ping was ok for lot of packets. Now, I try to access 192.168.2.1:80/myindex.html (apache) from laptop, and can see that own 1kb test page. But, trying to access 192.168.2.1:80/my.jpg, I see the following: GET /my.jpg HTTP/1.1 200 OK <jpg header, about a kilobyte> <TCP packet retransmisson> <TCP packet retransmisson> <end of stream> It seems to be a hostapd's problem (networked stuff worked fine with Ad-Hoc), but it may be also forwarding/routing problem too. What to google for? Even more strange, SSH to that host works fine.

• How can I implement ansible with per-host passwords, securely?

  - by supervacuo

  I would like to use ansible to manage a group of existing servers. I have created an ansible_hosts file, and tested successfully (with the -K option) with commands that only target a single host ansible -i ansible_hosts host1 --sudo -K # + commands ... My problem now is that the user passwords on each host are different, but I can't find a way of handling this in Ansible. Using -K, I am only prompted for a single sudo password up-front, which then seems to be tried for all subsequent hosts without prompting: host1 | ... host2 | FAILED => Incorrect sudo password host3 | FAILED => Incorrect sudo password host4 | FAILED => Incorrect sudo password host5 | FAILED => Incorrect sudo password Research so far: a StackOverflow question with one incorrect answer ("use -K") and one response by the author saying "Found out I needed passwordless sudo" the Ansible docs, which say "Use of passwordless sudo makes things easier to automate, but it’s not required." (emphasis mine) this security StackExchange question which takes it as read that NOPASSWD is required article "Scalable and Understandable Provisioning..." which says: "running sudo may require typing a password, which is a sure way of blocking Ansible forever. A simple fix is to run visudo on the target host, and make sure that the user Ansible will use to login does not have to type a password" article "Basic Ansible Playbooks", which says "Ansible could log into the target server as root and avoid the need for sudo, or let the ansible user have sudo without a password, but the thought of doing either makes my spleen threaten to leap up my gullet and block my windpipe, so I don’t" My thoughts exactly, but then how to extend beyond a single server? ansible issue #1227, "Ansible should ask for sudo password for all users in a playbook", which was closed a year ago by mpdehaan with the comment "Haven't seen much demand for this, I think most people are sudoing from only one user account or using keys most of the time." So... how are people using Ansible in situations like these? Setting NOPASSWD in /etc/sudoers, reusing password across hosts or enabling root SSH login all seem rather drastic reductions in security.

• vmware esxi 5, cant create snapshots and consolidate fails, how to delete old or consolidate redo logs?

  - by Scott Szretter

  I have a VM that seems to be working ok, but when VMWare DR (or I) tries to create a snap shot, it fails, and when I view the summary page of the VM it has a warning at the top showing that the disks need to be consolidated. So I go to snapshot manager for the VM and choose consolidate (in snapshot manager, there are no snapshots actually listed by the way). If fails with this error: This virtual machine has 255 or more redo logs in a single branch of its snapshot tree. The maximum supported limit has been reached, creating new snapshots will not be allowed. To create new snapshots, please delete old snapshots or consolidate the redo logs. If I browse the data store (which has plenty of free space, 2 TB and this vm is under 40gb), in the vm folder, I do in fact see a bunch of files, numbered all the way to 0255: myvm-000255-ctk.vmdk myvm-000255-delta.vmdk myvm-000255.vmdk How can I clean all this up? Is there an SSH command line command or can I delete some of the files safely? Thanks!

• Connect to Apache times out randomly

  - by Amadan

  We are trying to set up an Apache server on a remote machine, but we experience strange behaviour. Checking with telnet remote.machine 80, one of these things happen randomly: Connect and serve content normally (no delay) Connect after a long pause Connect normally, then time out without response Timeout on connect Once connected, the request seems to be processed normally. These things do not occur if I connect from that machine directly to localhost 80. The Apache is dedicated, as is the server it runs on (runs only this one application, no-one else is using it for anything else). I am not an administrator of the remote site, and I do not know the network architecture over there, but apparently it's firewalled: (HTTP port is open, SSH port is IP-restricted, most others are closed). If there was any one pattern, I might have some ideas, but this variety of symptoms baffles me. Any ideas as to what could be causing this? Apache is 2.2; Server version is: Linux version 2.6.9-22.ELsmp ([email protected]) (gcc version 3.4.4 20050721 (Red Hat 3.4.4-2)) #1 SMP Mon Sep 19 18:32:14 EDT 2005

• postfix - connection refused from behind NAT

  - by manchine

  When attempting to telnet postfix from a different host in the same LAN through the FQDN (and thus the LAN's public IP), the following error occurs: root@mailer:/var/log# telnet mail.domain.com 25 Trying 1.2.3.4... telnet: Unable to connect to remote host: Connection refused Other services can be reached from the exact same host, however: root@mailer:/var/log# telnet mail.domain.com 22 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. SSH-2.0-OpenSSH_6.0p1 Debian-4+deb7u1 To make matters more intriguing, Postfix can be accessed from outside the LAN: nunos-mbp:mailog nzimas$ telnet mail.domain.com 25 Trying 1.2.3.4... Connected to mail.domain.com. Escape character is '^]'. 220 mail.domain.com ESMTP Postfix (Ubuntu) To sum thing up: a) Postfix (running on 10.10.10.4 / mail.domiain.com) refuses connection from a host in the same LAN (10.10.10.2), but only when queried through the FQDN (mail.domain.com) b) mail.domain.com accepts connections to other services (but Postfix) from 10.10.10.2 c) mail.domain.com accepts connections to all services, including Postfix, from the outside world If it were a firewall issue, then I believe it would not be possible to connect to any service from 10.10.10.2 through the FQSN / public IP. It ought to be some missing parameter in Postfix, although I haven't found any clear pointers so far.

• Java: very slow tomcat and too big war file

  - by NaN

  I created some sort of RESTful API backend for a mobile app. It's written completely in Java using Jersey as Framework. At the moment no database is used, it's all in the memory, but this is no problem so far (it's only for prototyping purposes). I ordered the smallest package from digital ocean and installed tomcat7. All in all tomcat works, but I have three major problems: 1) It takes a long time until tomcat deploys the app: I deploy it per tomcat manager and it takes about 2 minutes unit the site works (excl. war upload time). 2) The war files are quite big (16MB): I don't know why they are so big. There are no database dependencies and most logic is written in plain java. Okay, we are using jersey, but 16MB are a lot for the logic of a small webservice. 3) I have to restart tomcat all 3 days or so. It looks like a memory leak or something similar. If the app runs for a few days the response time is quite high and the server seems to be frozen. It works again, if I restart tomcat per ssh. You can find my mvn pom file right here. Do you have some tips? Are there good tomcat alternatives?
