• Troubleshooting "connection reset" error on my linux server

  - by Chris

  I fervently hope someone here can help me with the problem I am experiencing. I am a programmer, and I have very little understanding of linux sysadmin terminology/concepts. I am attempting to troubleshoot a problem with my website. It is a Facebook app, and whenever I try to connect using Chrome, I get an error stating that the "connection was reset". I have been Googling for four days straight trying to find a solution to this problem, but no joy. A big part of the problem is that I do not understand the terminology being employed, and the output from many of the tools referenced is likewise indecipherable to me. I am running a VPS with CentOS 5, apache, PHP, and MySQL. I could spam this post with a ton of information from my iptables, apache, etc but if anyone needs information from my server, please let me know how to get it, and I will post it here. Thank you for any help you can offer!

• Trying to get a new user up on VPN

  - by Chris

  Caveat: I am not a sysadmin, so please forgive the n00bness of the query. We have a new user and I'm trying to get them up on VPN. We use pfsense as an IPSEC endpoint. This person is using Shrewsoft for the client. I had created an entry in pfsense for them and then edited a previous user's config file. Shrewsoft didn't import the config file very well and I had to hand edit the information. Now we are getting gateway errors. One thing I've noticed is that there is a different between the values of the preshared key stored on the firewall and the psk stored in the config file. I assume it has something to do with a hash, but I've no idea if that's the case and whether that might be what's causing the problem. Any suggestions greatly appreciated! Tangentially, is there some software used to generate these config files?

• Has ec2 made self-hosting possible for 'amateur' sysadmins possible?

  - by Blankman

  I'm a developer, and it seems ec2 has made it possible for a amateur sysadmin like me to setup and maintain a fairly large set of servers. Now I don't mean to undermine real sys admins, as I know the value of them but what I am trying to get at is that someone like me can setup and maintain a cluster of servers (front end web servers, with some db servers) using tools like ec2 and capistrano with the help of google. Now this isn't something I would do as a long term thing, but as a startup, one-man operation, I think I can pull this off until business takes off and I can hire this important role out. With ec2, I get my firewall, so I basically open up port 80 on my public facing server, which will run haproxy and route requests to my cluster of servers. Ofcourse I am simplifying the setup, but just want a feel for what you guys think about my perception. My application is a web application, that will be runing Ruby on rails (passenger) and talking to mysql or postgresql.

• Can a working Tomcat 6 webapp be turned into a usable .war file?

  - by Bill Cole

  Problem: I have a working webapp on a FreeBSD 8.1 Tomcat 6 test server that I need to move to a production system. The developer who last touched it (and had root on that server) has moved on and isn't helpful. The running app seems to have been deployed from a CVS server that is now unavailable. My thinking is that I would like to find a way to wrap the working webapp into a proper .war so that I can deploy it on a pristine host and (after testing) send the existing system to a very deep bitbucket. But I'm not having luck finding a way to do that. I'm a sysadmin not a developer and don't work much with Tomcat systems so I may be (likely am) overlooking something blindingly simple. I gather that I may be able to just tar up the deployed directory and untar it on the new machine, but I have a nagging feeling that there are pitfalls in that.

• Recoomend company to take care or webserver and wordpress management?

  - by javipas

  I'm interested in setting up a professional WordPress site but I'd like to explore the pssibilities to leave the management of the webserver and even WordPress' management to a company that guarantees great availability, performance of the site (load times, security) and even SEO. My site is currently running on other platform but I plan on a migration on the next 4 weeks. I've done this usually, but I'd like to focus on the content, so I don't have to mess with webserver/mysql/php configs in order to get nice performance. Is there some (maybe hosting) company that is dedicated to this? Would it be better to hire a sysadmin with experience in those matters?

• Recurring network issues the same time every day.

  - by Peter Turner

  Something has been happening on my company's network at 9:30 every day. I'm not the sysadmin but he's not a ServerFault guy so I'm not privy to every aspect of the network but I can ask questions if follow up is needed. The symptoms are the following : Sluggish network and download speed (I don't notice it, but others do) 3Com phones start ringing without having people on the other end. We've got the following ports exposed to the public for a web server, a few other ports for communicating with our clients for tech support and a VPN. We've got a Cisco ASA blocking everything else. We've got a smallish network (less than 50 computers/vms on at any time). An Active Directory server and a few VM servers. We host our own mail server too. I'm thinking the problem is internal, but what's a good way to figure out where it's coming from?

• How to elegantly selectively exclude FreeBSD network traffic from OpenVPN interface by port

  - by Polygonica

  inexperienced sysadmin here. I'm planning on running a net daemon inside a FreeBSD jail through OpenVPN, but want to be able to SSH directly into the jail and use the daemon's web interface daemon without going through the VPN. As I understand it, an OpenVPN tunnel is normally set up as a default virtual internet interface, and so incoming traffic will go out on the OpenVPN interface by default (which is problematic, as this incurs latency). I thought "well, obviously, since all of this traffic is leaving on a handful of ports, I'll just redirect those to the non-VPN gateway." I've tried to look for solutions, but almost all of them involve iptables instead of ipfw (which is default for FreeBSD) and solve slightly different problems. And alternate solutions like using multiple default routes to ensure that incoming traffic on any interface is always sent out on the same interface seem far-reaching and require deep knowledge of all tools involved. Is there an elegant way of ensuring that traffic leaving on specific ports exits on a specified non-default interface using ipfw?

• Should I run my own MTA?

  - by Mascarpone

  I need to send a large volume of emails, roughly 60.000 per week. At the moment we outsource this service to a third party, and we expect to double our volume within the next 6 months. Since the service is starting to be too expensive, I was thinking about setting up our own MTA. Our own SysAdmin told us it is not difficult at all to have our own MTA, but I'm afraid he might have oversimplified this. Is it difficult to handle a MTA? Should I be afraid that my MTA will lose the company mails? Should I stay with a third party service? p.s: The emails have been collected respecting the local legislation on privacy, so no spam.

• Edit exim4 Message-ID for releasing blocked mail by Mailscanner

  - by F12

  Our sysadmin team edits the field Message-ID in exim4 header files (ending with -H) and substitues the first char after "<". e.g: 077I Message-ID: <[email protected] -- 077I Message-ID: <[email protected] I'd like to write a script to release the mails. I changed the part between "<" and "@" in the field Message-ID and substituted a hash value so the Message-ID looks like: 077I Message-ID: <[email protected] Now exim says "format error" in the log and the mail is not released. There was no change except for this one field. Why can't the ID be substituted like that? Does it need to be the exact same length? It's exim4 version 4.69-2ubuntu0.3.

• Why is hosted storage so expensive?

  - by Mark Henderson

  There are many questions on Server Fault asking why server storage is so expensive. e.g. Why do I have to pay 50 bucks a month per extra gigabyte of storage or Our file server is always running out of space, why doesn't our sysadmin just throw an extra 1TB drive in there? These questions usually come from people who lack an understanding of how enterprise-level storage works and what influences the price. This question is designed to be the "question to end all questions" regarding the price of enterprise storage.

• Simple local smtp server - minimal setup ubuntu

  - by malatio

  What is the absolute, bare minimum, no-hassle, hopefully idiot-proof way of setting up a local smtp server? If you're going to say postfix, what are these alledgedly bare minimum, idiot proof steps to setting it up? I'm sort of amazed at how difficult it seems to find this anywhere. I need: a locally hosted smtp server that sends mail to the internet. no tls or saslauth or whatever. only allows mail to come from localhost. no relays. It seems like there should be some software package somewhere where you install, set up an account and then you have a local smtp server. I'm not a sysadmin. People say postfix is dead simple but maybe I'm doing it wrong, all the setup docs I see are quite complicated, I actually don't have a spare hour to spend debugging a mailserver. I just want to send mail to the internet. Is it really that hard?

• Mitigating the 'firesheep' attack at the network layer?

  - by pobk

  What are the sysadmin's thoughts on mitigating the 'firesheep' attack for servers they manage? Firesheep is a new firefox extension that allows anyone who installs it to sidejack session it can discover. It does it's discovery by sniffing packets on the network and looking for session cookies from known sites. It is relatively easy to write plugins for the extension to listen for cookies from additional sites. From a systems/network perspective, we've discussed the possibility of encrypting the whole site, but this introduces additional load on servers and screws with site-indexing, assets and general performance. One option we've investigated is to use our firewalls to do SSL Offload, but as I mentioned earlier, this would require all of the site to be encrypted. What's the general thoughts on protecting against this attack vector? I've asked a similar question on StackOverflow, however, it would be interesting to see what the systems engineers thought.

• Exchange 2007 OWA not listening on SSL port

  - by krs1

  I have an Exchange 2007 server that went down after a power failure. It has OWA access via SSL both externally and internally. OWA is working fine from the internal notwork, however I am getting a timeout when I attempt to connect externally. I pulled up wireshark and noticed that the server actually redirects to SSL. For some reason the server is not listening on the SSL port, and this seems to be causing the timeout. I normally do only development work, but I'm stuck with this since my sysadmin took off for the week and isn't answering my phone calls. As far as I know it shouldn't be a firewall issue. Aside from me not wanting to work on the damn thing, what should I look for?

• Apache web server: "proxying" a webapp from another server?

  - by Riddler

  Sorry for the lame terminology - I'm no way a sysadmin... So here's the deal. I have two Linux boxes in the same network, let's refer to those boxes by their IPs, a.b.c.d and e.f.g.h. Each box runs some webapp, normally available like http://a.b.c.d/ and http://e.f.g.h/. What I want to accomplish is this: with some Apache web server (which by the way lives on both boxes) configuration voodoo, the first app would be available via http://a.b.c.d/whatever1/, and the 2nd app would be available as http://a.b.c.d/whatever2/ - but would still reside on another server (e.f.g.h). Long story short - is it at all possible to do this with Apache configuration magic and without touching the webapps and their configuration? If so - how? :) Thanks in advance!

• Setting the server to look for index.php file by default

  - by ????? ???????

  I am a web developer and I've requested our Sys-Admin to setup a server for my team that will be used as a development environment. The PHP is running as a CGI. When i try to open http://myaddress/ I receive 403 Forbidden. When I try to open http://myaddress/index.php everything is fine. How do I set the server to look for index.php file by default? P.S The sysadmin is not currently here, so he cannot do it for me.

• ruby on rails server is intermittently slow

  - by Richard

  My rails installation was chugging along nicely. Last night we had to perform a hot-patch with was really a standard deploy of some exception code. Once capistrano finished the operation one of our admins discovered that there were two long running passenger processes. While we have deployed release over the past two weeks it would appear that these processes have been here and alive the whole time. Granted they could have been zombies or any other artifact and at this point we do not know what state they were in. Which leads me to the question: There are so many moving parts between the rails application and the OS/hardware that being a SME is probably no longer possible. So; how does a sysadmin perform root-cause analysis with any certainty? And: When do I just start rebooting servers?

• Updating Applications in a Corporate Environment

  - by user145133

  I am very new to this subject and was hoping someone could shed some light on it. I am working on creating a corporate network that will obviously have multiple servers and multiple workstations. Let's say a new version of Adobe Flash comes out. I would think that you would want to test this update in a test environment before "pushing it out" to the servers and workstations. How do you guys go about controlling, testing and then pushing the application updates out? (i am not talking about windows updates). Do you use a 3rd party sysadmin tool? Home grown software? Any info will greatly be appreciated :)

• How to make sure clients update their browser cache when my website is updated?

  - by user64204

  I am using the HTTP 1.1 Cache-Control header to implement client-side caching. Since I update my website only once a month I would like the CSS and JS files to be cached for 30 days with Cache-Control: max-age=2592000. The problem is that the 30-day period defined by Cache-Control doesn't coincide with the website update cycle, it starts from the moment the users visit the site and ends 30 days later, which means an update could occur in the meantime and users would be running with outdated content for a while, which could break the rendering of the website if for instance the HTML and CSS no longer match. How can I perform client-side caching of content for periods of several days but somehow get users to refresh their CSS/JS files after the website has been updated? One solution I could think of is that if website updates can be schedule, the max-age returned by the server could be decreased every day accordingly so that no matter when people visit the website, the end of caching period would coincide with the update of the website, but changing the server configuration every day goes against one of my sysadmin principles (once it's running, don't touch it).

• Application deployment with Puppet

  - by michaeltwofish

  I'm new to Puppet and while I've been using *nix systems for many years, I've never worked as a sysadmin or in ops. I'm currently writing Puppet manifests for hosting a set of (PHP/MySQL/MongoDB, code in git) web applications. Clearly Puppet needs to have some knowledge of the actual applications because I'll set up a virtual host for each one, but I'm not sure whether Puppet should be managing things like code deployment and database creation. Is Puppet an appropriate tool for application deployment? If not, can you recommend a more appropriate tool?

• Site's performance slows over time until Apache is restarted

  - by udbhav

  I'm running a Django app w/ Nginx and Apache. All our static media is stored on S3, and basically it takes a while for the app to check if thumbnails have been created every time a page is loaded. To alleviate this problem, I'm caching the output of the templates w/ memcached. Over the course of an hour or two, the site's speed goes down significantly, until I restart apache, and then all is good for a little while. I have very little sysadmin experience, and was hoping somebody could at least point me in the right direction.

• Is there a filesystem that is "friendly" to both windows and Linux?

  - by Somebody still uses you MS-DOS

  I'm planning to install Ubuntu 10.04 with Windows 7. (I'm new to Linux, have to use at work so I'm planning to install it at home to learn more) I plan to use a partition to my Windows system files (C:), a partition for my personal files that already exists (D:) and a new partition for Linux. What I want is to have a partition for my personal files that works across these systems - so, if I start with Windows or Linux, there's the same "Videos", "Pictures", "Projects" folders. Is it possible? Is there a hd filesystem capable of having writes from both systems without too much risk of corrupting or something? (Can't be FAT32, I need to store 4gb files). I've read some horror stories of corruption, and would like to know from a sysadmin POV all the risks involved in such scenario.

• migration of physical server to a virtual solution, what i have to do?

  - by bibarse

  Hello I'm new in this forum, so i would like that you forgive me for my blissfully and my low English level. I'm a trainee in company one month ago, and my mission is to migrate 3 physicals servers to a virtualization technology. The company edit softwares for E-learning so there are lots of data like videos, flash and compressed (zip). This is some inventory of the servers: OS: Debian, 2 redhat, apache, php/mysql, sendMail/Dovecot, webmin with virtualmin template to create dynamically the web sites because there is no sysadmin ... The future provider will be responsible of to secure, update and create the virtual machines (outsourcing) and with a RedHat OS's. So i want that you help me to choose a virtualisation technologie (for the i prefer KVM of Redhat RHEV, VMWare is expensive), how evaluate the hardware needs (this for evolution of 4 or 5 years) and to elaborate a good planing to don't forget any think. Thank you for your responses.

• Recommended laptops for system admins?

  - by 80skeys

  Hey all - I'm in the market for a new laptop and wanted to get some recommendations. I'm a Linux sysadmin and this laptop is primarily for work related use, working from home, after hours, occasional trips to the data center, etc. We all know the drill. My typical setup includes various utilities and tools plus multiple partitions for booting different OS's including VMware. Need serial port of course, DVD-RW, and all the usual stuff we use in our daily routine. I'm kinda thinking a Thinkpad T510 but open to other suggestions! Brief explanation of why you suggest some particular brand and configuration is appreciated.
