  • Sysadmin bad habits

    - by chmeee
    I think it would be interesting to have a list of bad habits you observe related to system administration. For example: Always using root on servers Sharing account passowrds Inserting passwords on code Still using telnet ... Although I'm mostly interested on security, you bad habit doesn't have to be security related. Bad habits stories are also welcomed.

  • Is there any USB2.0 data transfer chunk size limit?

    - by goldenmean
    With one read() or write() at a time, can we increase the bulk data size over USB interface? For example, I want to transfer chunk of 1024 (1K) bytes data and if the device has limitations of only 64bytes, is there any way I can increase the packet size for read() and write() system call over USB? Is there any limitation on size of data transfer over USB in a host-device environment?

  • Resolving CloudFlare DNS related mail delivery problems

    - by Andy Castles
    I recently started using CloudFlare and am having a few teething problems. Our domain is netlanguages.com and while we have a lot of sub-domains listen, we are currently only trialling a few of the servers through the CloudFlare CDN (for example, www.netlanguages.com is enabled for CDN, netlanguages.com is not). The actual CDN service seems to be reliable, but the problem that we are having is with DNS, and specifically with mail delivery. The background is that we have contact forms on our web site which use PHP mail() to send the details to end-users' email addresses, with the "from" address of the messages being [email protected] which is a valid address on our mail server. Most of the mails are arriving correctly, but a few specific people are not receiving them. The webserver uses qmail to deliver the messages, and the qmail log files show us some of the errors that the receiving mail servers return when they reject the mail delivery attempt. Two examples: Connected to 94.100.176.20 but sender was rejected./Remote host said: 421 DNS problem (interdominios.netlanguages.com). Try again later Connected to 213.186.33.29 but sender was rejected./Remote host said: 451 DNS temporary failure (#4.3.0) From what I can tell, the receiving SMTP server is doing a DNS lookup of some description on either the host of the "from" email address (netlanguages.com) or the server name given in the EHLO command of the SMTP conversation (in the first example above, interdominios.netlanguages.com), both of which should resolve to non-CloudFlare IP addresses. I've read that the CloudFlare DNS service is very reliable and fast but both of the problems above seem to point to a problem with remote servers unable to do DNS lookups. I should also point out that we changed our DNS to CloudFlare on 6th Feb, and since then started experiencing these mail delivery problems. On 22nd Feb we moved our DNS away from CloudFlare to see if the issues were related to CloudFlare and after a few hours delivery began to work. Then on 26th Feb I moved the DNS back to CloudFlare again and delivery problems started again. The issues definitely seems to be related to DNS, but I don't know if it's a configuration issue, or something else. Finally, I should say that our two DNS MX records point to non-CDN A record IP addresses, interdominios.netlanguages.com (the web and qmail server) also points to a non-CDN A record IP address. Does anyone know what the problem could be here? Any light you can shed on this will be most appreciated. Many thanks, Andy

    I was curious if there was a way to add a hook or something into CVS so that when you commit a text file or into CVS, it will add a certain string at the end of the file? For example, say something like: "Committed by Joe Schmoe on 03/11/2010"

  • Sharing software updates between macs without OS X Server

    - by Frost
    Is there any way to (manually or automatically) share downloaded software updates between macs? Edit: The thinking is that I have one mac update itself using Software Update, and then somehow share the downloaded updates with other macs. For example, I have a mac pro and a mac mini on my local network. I'd like to download the Mac OS X 10.6.5 update only once, instead of having to download it separately for each mac.

  • How does Windows Task Scheduler detect that a task is already running?

    - by Dan C
    I have an application on Windows Server 2008 that takes different command-line parameters. For example: myapp.exe /A myapp.exe /B I have created a task scheduler task for each of those. While "myapp.exe /A" is running, I want to prevent another instance of it from starting. However, I still want "myapp.exe /B" to be able to run (again, though only one instance of it at a time). How can I set this up?

  • Simple tool to graph memory usage?

    - by dbr
    Is there a script that will show memory usage as a graph, for example as a pie-chart, with each process being being a separate slice? I'm not looking for something like Munin to graph memory usage over time, but rather show the memory usage per-process at a single point in time. To make my request even more obscure, it is for a headless server (so no X applications). The simplest way would be to write a PNG file, or possibly an HTML file (which could use Javascript to allow the filtering of processes, changing between graph-types and so on)

  • Utility to determine the font used on a site?

    - by Lazer
    For example: I like the fonts used on the website : NYTimes, so something that could list all the fonts used by the website would be great! I do NOT want a image processing utility that could analyze the screenshots or a site that will ask questions about the font and narrow down from its list. Something that could just crawl the website and list its fonts... It would be great if it could overlay the fonts on the regions, but that would be going too far, I guess.

  • Router with Wake On LAN

    - by Jaroslav Záruba
    I'm looking for a new WiFi router, and one key feature for me is WOL. Seems like many routers won't do this w/ factory firmware. Given my last router (Asus WL-520g) turned into a disco-brick couple hours after flashed DD-WRT I'd prefer if the new one supported WOL (Wake on LAN) out of the box. Other required features would be: DynDNS service support Port forwarding NAT loopback so I can access services running in my own network using dyndns hostname or public IP w/o getting too old (for example DIR-615 with factory firmware lets you wait literally minutes)

  • Mnemonic external IP

    - by Click Ok
    When diagnosing networking problems, I ping to: My local IP My gateway IP An external IP An external domain name Usually, when troubleshooting, the internet is unaccessible, then I need to remember an external IP address. I need any (easy to remember) IP address. By example, google ip is 72.14.204.147. Cool, but it's hard to remember... What external IP you use? Do you have an mnemonic external IP address, then will be easy to remember?

  • cgconfig.conf : setting root control group parameters

    - by delerious010
    I've got cpu, cpuacct and memory cgroups configured via /etc/cgconfig.conf ( cgconfig-bin on Lucid ). I can add new control groups, and assign processes to them however there does not seem to be a facility for changing the paramters of the root level memory cgroup ( the actual mount point ). How would one best set such parameters in a clean manner withoput c For example, I've the memory cgroup mounted to /var/run/cgroup/memory. I'd like to have /var/run/cgroup/memory/memory.use_hierarchy set to 1 on boot.

  • Why do Chinese filenames displays as boxes in Windows 7?

    - by Roddy
    I'm running Windows 7 Professional (UK), and trying to get filenames containing Chinese characters to display correctly in Explorer. I can create Chinese filenames in explorer by pasting text from a webpage or using the Chinese IME to rename files, but the characters just display as boxes (Unicode 'missing character' glyph). The Chinese fonts are installed on the system, and web pages display OK in the browser. In particular, I can see the correct Chinese filenames by pointing chrome at file://C:\, for example.

  • How can I simulate blocking RTMP over port 80 on Windows?

    - by Christian Nunciato
    It seems like this should be so simple, but since this isn't my area of expertise, I'm having a hell of a time figuring out how to do it. Basically, I have a Flash app and I'm connecting to a Flash Media Server to stream some content. The URL I'm using to do this, for example, looks like this: rtmp://someserver.com/some/path/mp3:somefile Everything works -- but that's sort of the problem. When I'm trying to do is simulate my users attempting to play back my media under more restrictive conditions than the ones I have here (i.e., none) -- namely being stuck behind firewalls or proxy servers that block access to RTMP streams. Flash, according to Adobe, is equipped to handle proxy servers and firewalls automatically, like so (from the docs): When you do not specify a port number in an RTMP address, Flash will attempt to connect to port 1935. If it fails it will then try to connect to port 443; if that fails, it will try port 80. [And if that fails, it will attempt to connect via RTMPT (i.e., HTTP tunneling) on port 80.] So no coding is required to access ports 1935, 443, or port 80 if you do not specify a port in the RTMP address. The problem I'm having is setting up a reliable environment in which to test that this behavior actually happens. I'm on a Windows machine, for example, so with Windows Firewall, I can block certain ports and protocols (1935, 443), but I don't want to block port 80, because the final fallback protocol (RTMPT) is supposed to run on port 80, and Windows Firewall only gives me enough granularity (as far as I know, anyway) to block "all outbound TCP traffic to remote port 80" -- that is, I can't, apparently, block "all outbound RTMP traffic to port 80" while leaving RTMPT traffic to port 80 unaffected. My understanding thus far is that I'll probably need to set up a proxy server to do this. Is this correct? Or is there a simpler way (on Win 7, at least) to filter out RTMP to 1935, RTMP to 443, RTMP to 80, but still allow RTMPT to 80 (where all four hostnames are identical)? And if I do have to set up a proxy server, what's the simplest way to go on Windows? I've set up WinProxy, which seems a bit janky but apparently works -- but then what I can't figure out is how to tell Windows to force all TCP traffic (including RTMP, RTMPT and HTTO) through this proxy server so I can turn around and reject the requests for RTMP. Any help would be hugely appreciated. This isn't my realm of expertise and I've alreasdy spent more time on it than I probably should. :)
