• Secure data from a server to a workstation using jumper hosts

  - by apalsson

  Hello. I have a WWW-server, my problem is that the content is sensitive and should not be accessible for people without proper credentials. How can I improve the ease of use but still maintain security following scenario; The Server is accessed through a "jumper host", i.e. the client connects to the jumper using VPN-connection and uses RemoteDesktop to access the jumper. From the jumper he uses RemoteDesktop again to access the Server. Finally on the Server the user can access content using a WWW-browser. All the way from the VPN-client to the WWW-browser requires authentication using a SmartCard-token. This seems quite secure to me. Content only gets mirrored on the RemoteDesktop between Server and jumper, no cached files to worry about. Connection between jumper and client is protected using VPN(ssl), so no eavesdropping. But it is quite cumbersome for the clients with many steps and connections to open. :( So, how can I improve the user experience accessing my server without compromising security? Thanks.

• Why is it a bad idea to use a customer email as the from address

  - by Crab Bucket

  I've got an application that emails users once they have filled in a form. It uses a [email protected] as a from address. The customer wants it to use the email from the form as the from address which could be anything. I have been told that this is a bad idea due to spoofing/blacklisting and spam. I feel really vague about the exact reason about why this is a bad idea particularly as i've got to try to counsel the client out of this. Can someone explain to me why this is a bad idea. Interestingly the client has used a gmail account as the from address as a demo which not only works fine but has enabled the application to start sending emails (it wouldn't do it before with an email which was [email protected]). Erm - what is going on. I'm told one thing and the opposite works. Sorry - i know this is basic but I could find anything on a google search. Largely I think because I'm having trouble even framing the question. EDIT Thank you everyone - great answers. Interestingly the server sending the email and the mail box that it is going to are both behind the same firewall so the client says they are unconcerned about spam. Oh well.

• Trouble getting started with the STEALTH monitoring package

  - by dlanced

  Is anyone here familiar with the Linux-based STEALTH package (for monitoring FS integrity of client systems)? I'm trying to get started with a very simple configuration, but I'm running into trouble (this is running under Ubuntu 14.04): Config line `USE BASE/root/stealth/10.0.0.79' invalid STEALTH (2.11.02) started at Fri, 30 May 2014 15:25:00 +0000 Program terminated due to non-zero exit value for -type f -exec /usr/bin/sha1sum {} \; (EOC Fri May 30 15:25:00 2014 127) Stealth is creating a binary tmp file in the Stealth server root and generating a "report" file in the start directory, but not much else. Regarding the "USE BASE...invalid" error, and just to be sure, I manually created the directories in /root, but it didn't help. And, by the way, I am running stealth with sudo.

• On clients use generic driver for printer shared by CUPS

  - by Daniel

  I know this worked really easy with a recent CUPS version some years ago. Unfortunately I fail to do the following with latest CUPS nowadays. How to share a printer without using printer specific drivers on the clients with CUPS? The printer is a Samsung ML-2010. The important fact is that it needs a quite specific library for printing called splix. That is installed on the server and prints well. What makes trouble is using that printer over the network. I found out how to use Avahi under Linux to make use of DNSSD to advertise and discover printers. But as far as I understand the new CUPS offers the internal driver interface on the network. This has 2 major issues: anybody can fiddle with the driver and I don't trust any uncommon printer library to be "network secure" anyone who wants to use my printer including guests needs to install the specific drivers first I remember the old days when I could enable "Share this printer" on the CUPS server and all clients would magically detect the printer and just send their job data to the server and have it do the driver stuff. After everything a read I guess this is related to the changes Apple introduced with CUPS including dropping of the integrated network discovery protocol. If it helps: Server: Ubuntu LTS 12.04 Server with CUPS 1.5.3 Client: Arch Linux with current CUPS 1.6.1 On another box with Ubuntu the printer was setup automatically at least but the mechanism used the Splix library for that.

• iTunes copy just metadata (song and album ratings, playlists) from iPod

  - by Jared Updike

  I have an iPod touch that I synched with my Windows computer (iTunes 9.0 I think) until my harddrive failed and I lost my entire library. I rebuilt the library (songs) from a year old backup (and various other source for songs) but my playlists and ratings are of course a year old. My iPod itself has most of the playlists and ratings I care most about (favorite songs and albums, rated 4 and 5, for example). I have a catch 22 situation where I feel nervous that I haven't backed up my iPod in around 4 months (when my drive failed) so I'd like to back it up as soon as possible... but if I back it up I have to clear all the songs and playlists and copy them back, which I can't really do since I need to rebuild my playlists on my computer first (using the data only available on my iPod!) The question: is there a better way to READ the information off my iPod than doing it manually, song by song and album by album and playlist by playlist (XML, text dump, database, spreadsheet, anything). In other words, mostly I want the information (metadata like ratings and playlists, not songs) copied off the iPod so I can more quickly get my iTunes library ratings and playlists re-built (manually) so I can finally wipe the music and back up my apps, etc. Then I'd like to copy the music back immediately. The part I'd like to avoid is manually navigating everything on my iPod to read through all the playlists and ratings (50 GB, 6,000+ songs) as I re-enter all of that data by hand. I've done a few dozen albums and it's pretty time consuming having to tap around on the iPod. Reading from a spreadsheet (for example, or XML which I could write a script to get into spreadsheet form) would probably help tremendously, plus then I'd have a backup of that information somewhere besides just my iPod.

• The suggested way to handle pip(easy_install) with homebrew?

  - by Drake

  I know there are brew-gem and brew-pip but it is still really easy to get confused. Let's say my Mac OS X is 10.7.2. There are at least, as far as I know, 3 locations for Python modules (assume 2.7): /System/Library/Frameworks/Python.framework/Versions/2.7/ /Library/Python/2.7/site-packages /usr/local/lib/python2.7/site-packages/ (controlled within homebrew) For some Python modules, pip install them into 2, the so-called local/customized Python module location, and everything looks and works great. Ex, readline by *easy_install* (ipython suggested me to install readline by *easy_install* instead of pip) For some, it would try to install some miscellaneous files (ex, man, doc, ...) into system-wide location, which requires sudo! Ex, ipython insisted on installing man and doc into /System/Library/Frameworks/Python.framework/Versions/2.7/share/, which violates permission issue and all I can do is to use sudo. For some Python modules installed by brew, they are symbolic linked to /usr/local/lib/python2.7/site-packages/. Everything seems great except that you have to remember to add this location into PYTHONPATH. I am wondering any suggested and uniform way to handle those mass, or any explanation to make those stuff crystal clear.

• Mac OS X will only upload zero-byte files through FTP

  - by tabacitu

  I'm using Mac OS X Lion and i've been having this problem with FTP (any FTP client, mind you. I tried Transmit, FileZilla, Cyberduck and the Terminal, all with the same result) I can browse files in my FTP Client, but when I upload files, the client hangs for a few seconds, then thinks it uploaded the files successfully, but it only creates a new file with one blank line in it. Sometimes, it manages to upload 4-5 lines. It then returns: 226 - Error during read from data connection 226 Transfer aborted But 2xx is a success message. It is not a server issue, since any Windows machine will upload just fine using the same network. Can anybody figure out what the problem is? It renders my mac useless for web development. The problem persists with SFTP and FTP with SSL/TLS. Later edit: Solved! Ok, turns out the problem goes away when I take out my router and connect directly through PPPoE. So the problem is with the router, I thought. But no, the problem is with the mac that connects through a router that connects through a PPPoE and tries to upload using FTP. Pretty specific, I know. The problem is with the MTU (maximum transmission unit). Apparently, mac os x breaks the file into chunks that are too large for the router to send, because the router's MTU was set lower than Mac OS X's. My router's was 1492, which is ok, but my Mac's MTU was 1500, which is unacceptable. I don't even understand why it works directly with PPPoE. Anyway, if you encounter the same problem, this is how you diagnose and fix it: In terminal, run: ifconfig | grep mtu to see what the MTU is for en0 (or en1, mine was en0) If it's 1500, run sudo ifconfig en0 mtu 1300 This should solve it. If so, it may only be until the next restart. You can also change the MTU in System Preferences \ Network \ Ethernet - Advanced \ Hardware

• which is best smart automatic file replication solution for cloud storage based systems.

  - by TORr0t

  I am looking for a solution for a project i am working on. We are developing a websystem where people can upload their files and other people can download it. (similar to rapidshare.com model) Problem is, some files can be demanded much more than other files. The scenerio is like: I have uploaded my birthday video and shared it with all of my friend, I have uploaded it to myproject.com and it was stored in one of the cluster which has 100mbit connection. Problem is, once all of my friends want to download the file, they cant download it since the bottleneck here is 100mbit which is 15MB per second, but i got 1000 friends and they can only download 15KB per second. I am not taking into account that the hdd is serving same files. My network infrastrucre is as follows: 1 gbit server(client) and connected to 4 Nodes of storage servers that have 100mbit connection. 1gbit server can handle the 1000 users traffic if one of storage node can stream more than 15MB per second to my 1gbit (client) server and visitor will stream directly from client server instead of storage nodes. I can do it by replicating the file into 2 nodes. But i dont want to replicate all files uploadded to my network since it is costing much more. So i need a cloud based system, which will push the files into replicated nodes automatically when demanded to those files are high, and when the demand is low, they will delete from other nodes and it will stay in only 1 node. I have looked to gluster and asked in their irc channel that, gluster cant do such a thing. It is only able to replicate all the files or none of the files. But i need it the cluster software to do it automatically. Any solutions ? (instead of recommending me amazon s3) S

• Why doesn't SSHFS let me look into a mounted directory?

  - by Jan

  I use SSHFS to mount a directory on a remote server. There is a user xxx on client and server. UID and GID are identical on both boxes. I use sshfs -o kernel_cache -o auto_cache -o reconnect -o compression=no \ -o cache_timeout=600 -o ServerAliveInterval=15 \ [email protected]:/mnt/content /home/xxx/path_to/content to mount the directory on the remote server. When I log in as xxx on the client I have no problems. I can cd into /home/xxx/path_to/content. But when I log in on the client as another user zzz and then $ ls -l /home/xxx/path_to I get this d????????? ? ? ? ? ? content and on $ ls -l /home/xxx/path_to/content I get ls: cannot access content: Permission denied When I do $ ls -l /mnt on the remote server I get drwxr-xr-x 6 xxx xxx 4096 2011-07-25 12:51 content What am I doing wrong? The permissions seem to be correct to me. Am I wrong?

• Have servers behind OpenVPN subnet reach connecting clients

  - by imaginative

  I am trying to find some relevant documentation or what directives I need in either the OpenVPN server configuration or client configuration to accommodate for this use case. I have an OpenVPN server that clients connect to. The OpenVPN server can communicate directly with any of the clients already, this is not an issue. The client is able to reach any machine on the private subnet where OpenVPN resides, this is also not an issue. My issue is that the reverse is currently not possible - I have servers on the same subnet as the OpenVPN box that cannot reach any of the connecting clients. I'd like to be able to SSH to them and more, the same way the client can reach the servers behind the OpenVPN subnet. What do I need to do to make this possible? I already have masquerading rules set on the OpenVPN box: iptables -t nat -A POSTROUTING -s 192.168.50.0/24 -o eth0 -j MASQUERADE IP Forwarding is enabled: echo 1 >/proc/sys/net/ipv4/ip_forward I added a route on the server behind the private subnet to be aware of the route: 192.168.50.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 What am I missing?

• How to eliminate the domain suffix off my user profile folder when migrating to a new domain?

  - by Jerry Dodge

  We have just upgraded a decade old SBS 2003 server to a brand new SBS 2011 machine. During the process, over 30 other client/server machines on that domain also needed to be dis-joined and re-joined from the old domain to the new one. These domains have different names and is not migrated in any way. It's built from scratch. Since each client machine had very unique user profiles under this domain, we needed to make sure these were all backed up and migrated over to the new domain. For the most part, profiles were migrated with no hassle, just by renaming the user profile folder names. However, in one case, when I log in to my domain account, it creates a profile folder with a suffix of the new domain name. I have replaced all the files in the profile's root which begin with "ntuser" with the files of the new profile. The only problem is half the applications can't find their data, because the folder name is different. How can I change this folder name and maintain this profile on the new domain? I have deleted every user account (except admin), deleted their profiles/folders, removed them from the registry, and made sure every trace of this account was gone. The computer was basically a dummy with only an admin account. Then, I log into the machine under my new domain user account (same username as the old domain). It creates a profile folder with my username plus a suffix extension of the new domain name. The client machine is Windows 7 Ultimate, the old server was SBS 2003, and the new server is SBS 2011.

• Should I use nginx exclusively, or have it as a proxy to Tomcat (performance related)?

  - by Kevin

  I've planned to create a website that'll be pretty heavy on dynamic content, and want to know what would be the wisest choice for part of my webstack. Right now I'm trying to decide whether I should develop upon nginx, using PHP to deliver the dynamic content, or use nginx as a proxy to Tomcat and use servlets to deliver the dynamic content. I have a good amount of experience with Java, JSP, and servlets, so that's a plus right off the bat. Also, since it is a compiled language, it will execute faster than PHP (it is implied here that Java is around 37x faster than PHP) , and will create the web pages faster. I have no experience with PHP, however i'm under the impression that it is easy to pick up. It's slower than Java, but since the client will only be communicating with nginx, I'm thinking that serving the dynamically created web pages to the client will be faster this way. Considering these things, i'd like to know: Are my assumptions correct? Where does the bottleneck occur: creating pages or serving them back to the client? Will proxying Tomcat with nginx give me any of nginx performance benefits if I'm going to be using Tomcat to generate the dynamic content (keeping in mind my site is going to be heavy in this aspect)? I don't mind learning PHP if, in the end, its going to give me the best performance. I just want to know what would be the best choice from that standpoint.

• SSH to remote host (edgemarc 4200 or 4500 series routers) and pull arp data

  - by MaQleod

  I've been trying to think of a method to do this for days, but have not come up with anything yet. Ideally, this is what I'm looking to do: From a windows XP machine, I need to open an SSH connection to a remote host, send the arp command, and pull the text results of the command back for use on the client. I will need to parse this data and preferably produce a 2D array of IPs and MAC addresses. There will be no shared keys, this is all done with a username and password that will always be different, they will need to be fed into the command via variables that will be pulled from a database using an autoit script based on the WAN ip of the remote host. Now the actual parsing of the data and creation of the array will be easy if I can just get the text of the arp table. Is there any way to ssh to a remote host, run a command and return the data from that command to the client in a batch script or perl script (it is ok if it writes the text to a file, I can read it out of the file later, I just need it to get to the client)?

• Nginx Multiple If Statements Cause Memory Usage to Jump

  - by Justin Kulesza

  We need to block a large number of requests by IP address with nginx. The requests are proxied by a CDN, and so we cannot block with the actual client IP address (it would be the IP address of the CDN, not the actual client). So, we have $http_x_forwarded_for which contains the IP which we need to block for a given request. Similarly, we cannot use IP tables, as blocking the IP address of the proxied client will have no effect. We need to use nginx to block the requested based on the value of $http_x_forwarded_for. Initially, we tried multiple, simple if statements: http://pastie.org/5110910 However, this caused our nginx memory usage to jump considerably. We went from somewhere around a 40MB resident size to over a 200MB resident size. If we changed things up, and created one large regex that matched the necessary IP addresses, memory usage was fairly normal: http://pastie.org/5110923 Keep in mind that we're trying to block many more than 3 or 4 IP addresses... more like 50 to 100, which may be included in several (20+) nginx server configuration blocks. Thoughts? Suggestions? I'm interested both in why memory usage would spike so greatly using multiple if blocks, and also if there are any better ways to achieve our goal.

• 100% uptime for a web application

  - by Chris Lively

  We received an interesting "requirement" from a client today. They want 100% uptime with off-site failover on a web application. From our web application's viewpoint, this isn't an issue. It was designed to be able to scale out across multiple database servers, etc. However, from a networking issue I just can't seem to figure out how to make it work. In a nutshell, the application will live on servers within the client's network. It is accessed by both internal and external people. They want us to maintain an off-site copy of the system that in the event of a serious failure at their premises would immediately pick up and take over. Now we know there is absolutely no way to resolve it for internal people (carrier pigeon?), but they want the external users to not even notice. Quite frankly, I haven't the foggiest idea of how this might be possible. It seems that if they lose Internet connectivity then we would have to do a DNS change to forward traffic to the external machines... Which, of course, takes time. Ideas? UPDATE I had a discussion with the client today and they clarified on the issue. They stuck by the 100% number, saying the application should stay active even in the event of a flood. However, that requirement only kicks in if we host it for them. They said they would handle the uptime requirement if the application lives entirely on their servers. You can guess my response.

• Interaction between two Clouds

  - by Snehal Masne

  I have setup the Cloud-A with 1 - [CLC+CC] and 2 - [NC] computers. I have another Cloud-B with same configuration. [using the Ubuntu Enterprise Cloud] Both of them working fine individually, in the same LAN. Now if I want to add the NC of Cloud-A to CC of Cloud-B, [in case the resources of Cloud-B are exhausted] how can I make it possible ? I guess this calls for the interoperability stuff... Could you please explain what happens exactly when we ask for instance, the direct interaction happens between the client and NC or it goes through the CLC and CC ? What I want to say is, say there are multiple cloud providers. A user is subscribed to any one of them, say Cloud-A for IaaS. As the requirements are dynamic, all the resources of Cloud-A may get exhausted. There may be another Cloud-B which can provide the services but that Cloud-A can't ask the client to go for Cloud-B. So if it is possible to have some co-ordination between this two providers to share resources mutually, making client fully unaware of whats going on in the background....? Please reply.. I am sorry if I'm doing mistake anywhere... Thanks in advance :) Regards, www.TechProceed.com

• Strange File-Server I/O Spikes - What Is Causing This?

  - by CruftRemover

  I am currently having a problem with a small Linux server that is providing file-sharing services to four Windows 7 32-bit clients. The server is an AMD PhenomX3 with two Western Digital 10EADS (1TB) drives, attached to a Gigabyte GA-MA770T-UD3 mainboard and running Ubuntu Server 10.04.1 LTS. The client machines are taking an extremely long time to access/transfer data on the file server. Applications often become non-responsive while trying to open files located remotely, or one program attempting to open a file but having to wait will prevent other software from accessing network resources at all. Other examples include one image taking 20 seconds or more to open, and in one instance a user waited 110 seconds for Microsoft Word 2007 to save a document. I had initially thought the problem was network-related, but this appears not to be the case. All cables and switches have been tested (one cable was replaced) for verification. This was additionally confirmed when closing down all client machines and rebooting the server resulted in the hard-drive light staying on solid during the startup process. For the first 15 minutes during boot, logon and after logging on (with no client machines attached), the system displayed a load average of 4 or higher. Symptoms included waiting several minutes for the logon prompt to appear, and then several minutes for the password prompt to appear after typing in a user name. After logon, it also took upwards of 45 seconds for the 'smartctl' man page to appear after the command 'man smartctl' was issued. After 15 minutes of this behaviour, the load average dropped to around 0.02 and the machine behaved normally. I have also considered that the problem is hard-drive-related, however diagnostic programs reveal no drive problems. Western Digital DLG, Spinrite and SMARTUDM show no abnormal characteristics - the drives are in perfect health as far as the hardware is concerned. I have thus far been completely unable to track down the cause of this problem, so any help is greatly appreciated. Requested Information: Output of 'free' hxxp://pastebin.com/mfsJS8HS (stupid spam filter) The command 'hdparm -d /dev/sda1' reports: HDIO_GET_DMA failed: Inappropriate ioctl for device (the BIOS is set to AHCI - I probably should have mentioned that).

• Emails sent from Coldfusion using the same SMTP/Exchange server works from one machine but fails for another

  - by Peter Herdenborg

  First, apologies if this question is too vague or has too little information to really be answerable. I am not normally working with these issues, and I don't have full access to the environment. However, the hosting provider seems to have a hard time tracking down the issue, so I am hoping that someone can at least provide me with some qualified guesses about the most likely problem. Here goes: A client I work for has a hosted IT environment, based on virtual machines running Windows 2008 R2 Standard. Our website, based on Coldfusion 9 was recently migrated from one virtual machine to another, and though Coldfusion is configured in the exact same way, using the same SMTP server, i.e. the client's Exchange server hosted in the same environment and in the same AD as both web servers, sending emails to external recipients is no longer working. It is still working fine when testing from the old machine. This is what I've learnt so far (all emails are sent using a valid from-address on the client's domain): Emails sent to other recipients on the same domain are delivered without any problem. Emails sent to external recipients on other domains are never delivered. When sending emails to both internal and external recipients, no emails are delivered. When receiving one of these emails to an internal address, the sender is now indicated as "[email protected]", while when sent from the old machine, it used to say just "sender". This seems to me that it could hint that the Exchange machine "recognizes" the old web server while it is a stranger to the new. In Coldfusion's mail log, all messages appear to be successfully delivered to the SMTP server. Any ideas what settings to look at, what log entries to search for or how to compare the old web server with the new one will be highly appreciated.

• Every month, scheduled task fails and password must be reset - why?

  - by Ducain

  [NOTE: I posted this originally at StackOverflow but it got no traction there - reposting here.] We have a bit of software installed at a few client locations that runs (via Windows task scheduler) a few times each day. In ONLY ONE of the client locations, we have a unique problem: each month, the task will stop working, after running every day for weeks. Twice now it's failed on the 2nd of the month. When I walk the client through troubleshooting it, we've found that it can't start - access denied. To fix it, we simply re-enter the same exact password, and then off it goes happy as a clam. I've never heard of this issue, and their IT people say they don't have anything running once a month that might cause that. I'm at a complete loss here. Any ideas as to why this might be happening? Further details: Windows XP pro machine. Task is being fired with credentials from a local admin account. Computer is always on, and connected to the net.

• Siege - running a stress test benchmark

  - by morgoth84

  I need to do a benchmark test of a HTTPS server using Siege, to see how it behaves under massive load. I'm initiating tests from another machine which is quite powerful and it is connected to the same physical switch the server is connected on. But when I initiate a test, I can't get it to make more than 170 requests per second. With this load the server's CPU usage is at 15-20% and the average response time for a request is approx. 0.03 seconds. Load of the client machine is approx. at 10%. So, I gradually increase the number of users in Siege (the number of worker threads) and request rate linearly increases up to 170 reqs/sec, but it never gets over it. No matter how many more worker threads I start, the load on the server is never more than 20% (and the client's load also doesn't increase any more). How can I overcome this? I've googled a bit and found out that after a request is completed, a socket associated with one ephermal port remains in WAIT_TIME state for some time during which it can't be reused. I tried to overcome this by doing these things: sysctl -w net.ipv4.ip_local_port_range="1024 65535" echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle Oh, and the client machine is a Linux (RedHat, I think, but I'm not sure). Any help would be appreciated.

• Block SMTP connections from mail domains which don't themselves accept SMTP connection.

  - by bignose

  I'm administrating a mail service for a small business. Their mail host's internet connection is an ADSL service with a permanent IP address. Unfortunately, many misconfigured mail systems will happily deliver to this host, but, when the host attempts to send mail back (e.g. a bounce notice, or a normal response from someone), the original sender refuses to receive connections from this host. That misconfiguration makes their system a one-way mail sender, which is a problem. How can I configure Postfix on this customer's mail host to refuse SMTP sessions that declare a sender domain which itself refuses SMTP from this host? That is, if the SMTP client declares a domain that we can't make SMTP connections back to, then there's not much point accepting the incoming connection in the first place. I'm imagining a late check (after the low-cost checks to winnow most of the rubbish connections) that keeps the client on the other end while it attempts an SMTP client connection back to the declared domain of the sender. If that connection is rejected, the incoming one is also rejected. I'm also open to other suggestions for how this problem might be addressed (short of not using this mail host at all, which isn't an option).
