  • bad printer isolation on print server or better way?

    - by Joseph
    I have noticed that when a printer or driver screws up on a Windows server it usually locks up or kills the print spooler and everyone can't print until it is fixed. Usually we have to put the troublesome printer on another server so when it fails, it doesn't take the whole group with it. That is assuming we ever figure out which printer is the problem. Is there a way to have it so that one bad apple doesn't ruin the bunch? Even if it is another form of printer serving, that would work as long as it's not hard for the user to find a printer and install drivers.

  • Good Wireless Range Extender

    - by Joseph Sturtevant
    Can anyone recommend a good wireless (802.11g) range extender? I would like to find something that will provide reliable wireless to areas of the building that aren't covered or get poor reception. I would also like a product that won't require big changes to my current wireless setup (multiple APs with a wireless controller are out). Latency and bandwidth aren't terribly important. Does anyone have experience with a product like this?

  • Odd Tools and Techniques for System Administrators

    - by Joseph Kern
    There's been a lot of questions centering on Software Tools for System Administrators. But I would like to know about any odd physical tools or techniques that you've used; Something that you never expected to be useful, but ended up saving the day. I'll go first: A Camera Phone. An application server had a major power issue that borked the RAID. Many of the disks were offline. Before I took the plunge and forced disks back online, I took a picture of the RAID BIOS screen with my camera phone. Having the exact layout of the RAID stored safely in my pocket, I was able to reset the RAID, and reboot the server. What odd tools/techniques have you used?

  • EC2 out of space on root disk, moving it to ephemeral

    - by Joseph Misiti
    I am spawning a few test servers on ec2 that happen to be m1.larges. I am using these test servers for load balancin testing. Anyways, most of the servers I have used before have been backed by EBS, but these instances (ubuntu 11.04) obviously come with a lot of ephemeral space located @ /mnt. What I noticed that is happening is I am running on space on the root disk. I am trying out this tutorial http://www.turnkeylinux.org/docs/using-instance-storage moving my /home + /usr directories to /mnt and then remounting them. This works except it does not survive a reboot. Am I missing something here or is this tutorial not completely correct. How do I make space on my / drive so I can do stuff and survive re-boots.

  • Recycle Bin for Windows Server 2003 File Shares

    - by Joseph Sturtevant
    One of the networks I administrate uses Windows Server 2003 File Shares to provide network storage for users. To prevent against accidental deletion, I use Shadow Copies to create snapshots twice a day. This method is only effective, however, for files which were on the share during the last snapshot. When users accidentally deleted files recently placed on the share, I have no recourse except to remote desktop into the server and attempt retrieval with an undelete utility (this is only effective if the file has not been overwritten). Is there a feature like the Windows Recycle Bin for Windows Server 2003 File Shares? What is the best way to protect my users against accidental file deletion in this scenario?

  • Postfix: Relay access denied

    - by Joseph Silvashy
    When I telnet to my server thats running postfix and try to send an email: MAIL FROM:<[email protected]> #=> 250 2.1.0 Ok RCPT TO:<[email protected]> #=> 554 5.7.1 <[email protected]>: Relay access denied I couldn't really find the answer on the site or by looking at other users question/answers, I'm not sure where to start. Ideas? Update So basically looking at the docs: http://www.postfix.org/SMTPD_ACCESS_README.html (section: Getting selective with SMTP access restriction lists), I don't seem to have any of those directives in etc/postfix/main.cf like smtpd_client_restrictions = permit_mynetworks, reject or any of the other ones, so I'm quite confused. But really I'm going to have a rails app connect to the server and send the emails, so I'm not sure how to handle it. Here is what my config file looks like: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) biff = no # appending .domain is the MUA's job. append_dot_mydomain = no # Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache # See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for # information on enabling SSL in the smtp client. myhostname = rerecipe-utils alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = $myhostname, localhost.$mydomain, localhost, mail.rerecipe.com, rerecipe.com relayhost = mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all inet_protocols = all mynetworks = 127.0.0.0/8 204.232.207.0/24 10.177.64.0/19 [::1]/128 [fe80::%eth0]/64 [fe80::%eth1]/64 Something to note is that relayhost is blank, this is the default configuration file that was created when I installed Postfix, when testing to connect with openssl I get this: ~% openssl s_client -connect mail.myhostname.com:25 -starttls smtp CONNECTED(00000003) depth=0 /CN=myhostname verify error:num=18:self signed certificate verify return:1 depth=0 /CN=myhostname verify return:1 --- Certificate chain 0 s:/CN=myhostname i:/CN=myhostname --- Server certificate -----BEGIN CERTIFICATE----- MIIBqTCCARICCQDDxVr+420qvjANBgkqhkiG9w0BAQUFADAZMRcwFQYDVQQDEw5y ZXJlY2lwZS11dGlsczAeFw0xMDEwMTMwNjU1MTVaFw0yMDEwMTAwNjU1MTVaMBkx FzAVBgNVBAMTDnJlcmVjaXBlLXV0aWxzMIGfMA0GCSqGSIb3DQEBAQUAA4GNADCB iQKBgQDODh2w4A1k0qiPNPhkrPj8sfkxpKPTk28AuZhgOEBYBLeHacTKNH0jXxPv P3TyhINijvvdDPzyuPJoTTliR2EHR/nL4DLhr5FzhV+PB4PsIFUER7arx+1sMjz6 5l/Ubu1ppMzW9U0IFNbaPm2AiiGBQRCQN8L0bLUjzVzwoSRMOQIDAQABMA0GCSqG SIb3DQEBBQUAA4GBALi2vvk9TGKJubXYJbU0PKmVmsfzFK35yLqr0keiDBhK2Leg 274sWxEH3ds8mUaRftuFlXb7RYAGNlVyTuMTY3CEcnqIsH7F2McCUTpjMzu/o1mZ O/B21CelKetBd1u79Gkrv2vWyN7Csft6uTx5NIGG2+pGi3r0gX2r0Hbu2K94 -----END CERTIFICATE----- subject=/CN=myhostname issuer=/CN=myhostname --- No client certificate CA names sent --- SSL handshake has read 1203 bytes and written 360 bytes --- New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 1024 bit Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Session-ID: 1AA4B8BFAAA85DA9ED4755194C50311670E57C35B8C51F9C2749936DA11918E4 Session-ID-ctx: Master-Key: 9B432F1DE9F3580DCC6208C76F96631DC5A4BC517BDBADD5F514414DCF34AC526C30687B96C5C4742E9583555A118232 Key-Arg : None Start Time: 1292985376 Timeout : 300 (sec) Verify return code: 18 (self signed certificate) --- 250 DSN Oddly enough when I try to send an email from the machine itself it does work: echo test | mail -s "test subject" [email protected]

  • Keeping my zsh or bash profile synced up on all my machines.

    - by Joseph Silvashy
    I work on several different machines, all of which are *nix. I have a lot of specific things I like my shell to, or the prompt to look like, or aliases, etc, etc. I'm sure all of you folks deal with this as well. What do you think the best way to keep all my machines' shells to act the same? First off, I'm aware that different machines will need different paths to bins and other differences, so my first inclination is to just include a file at the end of my profile, this is the one that we'll keep in sync. What is the best way to keep files synced up? I can put the file on a remote system, and perhaps use git, to push, then pull my changes every once and a while. However, isn't Rsync better suited for this?

  • When running a shell script, how can you protect it from overwriting or truncating files?

    - by Joseph Garvin
    If while an application is running one of the shared libraries it uses is written to or truncated, then the application will crash. Moving the file or removing it wholesale with 'rm' will not cause a crash, because the OS (Solaris in this case but I assume this is true on Linux and other *nix as well) is smart enough to not delete the inode associated with the file while any process has it open. I have a shell script that performs installation of shared libraries. Sometimes, it may be used to reinstall versions of shared libraries that were already installed, without an uninstall first. Because applications may be using the already installed shared libraries, it's important the the script is smart enough to rm the files or move them out of the way (e.g. to a 'deleted' folder that cron could empty at a time when we know no applications will be running) before installing the new ones so that they're not overwritten or truncated. Unfortunately, recently an application crashed just after an install. Coincidence? It's difficult to tell. The real solution here is to switch over to a more robust installation method than an old gigantic shell script, but it'd be nice to have some extra protection until the switch is made. Is there any way to wrap a shell script to protect it from overwriting or truncating files (and ideally failing loudly), but still allowing them to be moved or rm'd? Standard UNIX file permissions won't do the trick because you can't distinguish moving/removing from overwriting/truncating. Aliases could work but I'm not sure what entirety of commands need to be aliased. I imagine something like truss/strace except before each action it checks against a filter whether to actually do it. I don't need a perfect solution that would work even against an intentionally malicious script. Ideas I have so far: Alias cp to GNU cp (not the default since I'm on Solaris) and use the --remove-destination option. Alias install to GNU install and use the --backup option. It might be smart enough to move the existing file to the backup file name rather than making a copy, thus preserving the inode. "set noclobber" in ~/.bashrc so that I/O redirection won't overwrite files

    - by Joseph
    I have a HAProxy setup in front of webservers(apache) for loadbalancing. Also healthchecks for these webservers are also configured in HAProxy. option httpchk HEAD /healthcheck.txt HTTP/1.0 Is it possible to transfer these healthcheck requests to backend webservers as "LB-Check" User-agent or any other option, so that I can distinguish it from other log entries? However I dont want to go for "dontlog" option, as I dont want to miss these entries.

  • SQL Server Agents jobs and turning off the server

    - by Tim Joseph
    I'm really new to SQL Agent jobs, but I am attempting to build up a maintainance regime for a server that will be turned off and on again at unknown intervals. It may run without being shutdown for a month, or it might only be turned on 9-5... we don't know and the client can't tell us because they don't know. So what I'm wondering is, what do I need to do to get SQL Server to run monthly and daily jobs either when they are due, or if the due date is missed, get them to be run when the server is next powered on. I could come up with a mish-mash of periodic jobs and 'on-power-up' jobs, but if there is something more elegant that would be wonderful. Obviously I'll need to ensure the SQL Server Agent is configure to start when the computer is powered up, but what else?

  • where are flash settings stored locally on Ubuntu

    - by Joseph Mastey
    It's possible change flash settings on your computer at this URL: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager03.html However, given that Macromedia has no problems setting LSO cookies on your HDD that you cannot find, I am a little bit skeptical that the settings I've tweaked there would be saved. So, I'd like to be able to look locally on my PC and verify the settings. Where can I find the settings for Flash locally? Surely the plugin cannot be heading to Macromedia itself for them (that is a future too bleak to contemplate). I am running Ubuntu 10.04. Thanks, Joe

  • Cisco T1 Routing Help

    - by Joseph
    Thanks to someone on this site I was able to get the Serial0/0 interface up. I now have: DCD=up DSR=up DTR=up RTS=up CTS=up My next challenge seems to be in the routing and/or PC ip setup. This are the pertinent details from L3: WAN Network: 6.59.186.60/30 Level3 Side: 6.59.186.61 Customer Side: 6.59.186.62 Cust. LAN IPs: 6.59.192.224/27 What would be the IOS commands to setup this route correctly? Am I correct that I would the choose an IP like 6.59.192.224, subnet 255.0.0.0, gateway 6.59.186.62? Thanks

  • creating decision tree based troubleshooting documentation?

    - by Joseph
    We troubleshoot a lot of server and network issues and follow a loose set of steps on what to do in different cases. With more and more people and responsibility, the need for standardization is needed so we don't miss something. I know I could accomplish what I want using flowcharts, but I'd like to do something similar to a "Choose Your Own Adventure" style. I think this is pretty much the same as what support call centers seem to do. Are there any tools to make creating such documentation easier? I'm looking for a web based approach if possible.

  • How exactly does processing files work on AFP shares?

    - by Oliver Joseph Ash
    I recently made myself a NAS, and I’ve been wondering about how AFP shares work. If I have a ZIP on the AFP share, and I use Finder to decompress the file, what will the process for decompressing this file be? Will it read the file into memory on my Mac, process it, and then write the results to the AFP share? I’ve been wondering because if I login via SSH to decompress, I seem to get faster results.

  • wireless ethernet adapter with EAP-PEAP?

    - by Joseph
    We have a wireless network set up to support WPA or WPA2 with AES or TKIP encryption and EAP-PEAP authentication. Users are wanting to connect devices that don't have the ability to do EAP-PEAP but have ethernet ports. I have found a wireless printer server that can do this, but I have yet to find a wireless ethernet adapter that can. Has anyone seen one with this ability?

  • Alternative shell apps for OS X

    This might sound ridiculous, but my eyes are tired of looking at the crappy font rendering in OS X's Terminal.app, is there anything you guys recommend? I know it's like one of those things that you can easily say, "It's shell! what more can you ask for!" but really, all these great methods for rendering fonts and anti-aliasing, and we developers haven't even integrated that into our most trusty tool... at least that I know of. Anyhow, let's discus shell alternatives, thoughts?

  • Can't connect to my FTP server, why?

    - by Joseph
    I have a windows 2008 server running with FTP 7 on IIS 7. I have it configured to connect as it is out of the box, with a particular user (lets say john) with read/write access. When I use my FileZilla client software, I can connect to the server as john just fine. No problems at all. However, when I try to connect using Windows Explorer or using the cmd prompt I get stone walled, saying "Login failed". My client machine is Windows Vista Ultimate. Does anyone know what might be causing this?

  • hyper-v server 2003 instance using internet connection sharing disconnects remote desktop to hyper-v host

    - by Joseph Southwell
    I have a windows server 2003 R2 instance running in a hyper-v instance on windows 8. I have setup an internal switch that uses internet connection sharing to get out to the internet. It works fine except for when I try to do windows update on the server 2003 instance it disconnects my remote desktop session to the windows 8 hyper-v host. When I reconnect it says windows update failed. I know that sounds crazy but I have tested it over and over again. If I change the instance to use my external switch (I have an external switch defined on another network adapter) windows update works fine.

  • script Disk Management configuration

    - by Joseph
    I have 10 workstations with large monitors that have USB slots and several card readers built in. The card readers cannot be disabled and will map to drive letters when I image the computers. I go into Disk Management and delete the drive mappings and add mappings to a single folder in C:\ with a folder for each slot. I have to do this because of scripts that run that are expecting specific letter drive mappings to network resources. Is there a way to script the deleting and adding of drive mappings instead of having to use the Disk Management GUI manually on each workstation? The workstations are running XP Professional.
