  • AWS RDS connection count

    - by wmarbut
    I am using AWS RDS with MySQL for a project and have a "large" instance. The documentation is clear on what this means as far as compute resources and RAM goes, but I can't find anything that documents how many open database connections that I can have. The app that I am using is PHP and it utilizes PDO with persistent connections. This means that the number of open connections could reach the maximum number of PHP child processes running at any given point. How do I ensure that my RDS instance has a max connections setting high enough to be comfortable with this?

  • Way to avoid ssh connection timeout & freezing of terminal tab

    - by Tchalvak
    When I connect via ssh terminal to certain servers, it timeouts and "freezes" the terminal (doesn't accept, doesn't disconnect, can't Ctrl-C to kill the ssh process or anything). This is in Ubuntu's Gnome-terminal, though it seems to be pausing the terminal input/output, and doesn't affect the operation of the Gnome-terminal software itself. so less a bug with gnome-terminal than an annoying inconsistency with ssh. So is there a way to prevent regain the terminal from ssh connections that have timed out?

  • External Hard Drive Won't Mount - MAC OSX

    - by dtj
    I have a Western Digital hard drive that's about 4 or 5 years old. It's 500 GB, USB. I use it to backup my Mac every so often. I had it partitioned: 1 side for full backups, and the other side for general storage of music, installers, etc. I decided to get rid of the partition today and dump all the data. So I opened disk utility, and hit 'erase'. It started thinking and then disk utility crashed. After the crash, the hard drive won't mount, however disk utility still sees the drive, but not the individual volume within. I tried booting up Disk Warrior and no luck there either. It has the drive as an "unknown drive". When I hit rebuild, it goes through all it steps and then stops cause of this error: The drive "unknown" is severely damaged and DiskWarrior is unable to determine its case sensitivity What can I do at this point? There isn't any physical damage to the drive. Never been dropped or anything.

  • SharePoint Server 2007 Stops Responding to External Requests

    - by Mountain Deux
    We have a SharePoint2007 server running on a Windows Server 2003 Box. The box itself is quite old but has not experienced any weird issues. Recently SharePoint has begun to show some strange behavior. One of the most annoying things is that once in a while, the sharepoint sever stops responding to requests outside our network. Internally, you can still browse everything that has to do with sharepoint but outside, nothing. If i reset the server it will start responding again. I am just not sure what makes it stop responding to users on the outside in the first place. Resetting the WWW publishing service does no good.

  • IRC newbie needs detailed "How To" directions for freenode.net connection with OS X IRC app

    - by Johnny Utahh
    Newbie IRC user here. Trying to get connected on freenode.net, preferably with a native Mac OS X client (I'm running 10.6.8), or at least something with a good "OS X feel." Also seeking a client that comes "well regarded" in Mac community (eg, Linkinus reflects outstanding Apple App Store user ratings). Thus far have found it remarkably difficult to "get started from scratch" with ANY client. All attempted clients (Colloquy, Textual, Linkinus) experience some sort of "* Notice -- You need to identify via SASL to use this server" error. I see this freenode SASL-friendly client list; am I really limited to only these clients? This "IRC-freenode startup" procedure has been far more difficult than I had originally anticipated. Why can't I just do this and have it "just work"? Bottom line: looking for a "chapter and verse"/cookbook description of how to get started with freenode.net IRC chat rooms on Mac OS. Need reference to known-working client, and then exact directions on how to get connected to a chat room with a nickname.

  • Linux - Only first virtual interface can ping external gateway

    - by husvar
    I created 3 virtual interfaces with different mac addresses all linked to the same physical interface. I see that they successfully arp for the gw and they can ping (the request is coming in the packet capture in wireshark). However the ping utility does not count the responses. Does anyone knows the issue? I am running Ubuntu 14.04 in a VmWare. root@ubuntu:~# ip link sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether 00:0c:29:bc:fc:8b brd ff:ff:ff:ff:ff:ff root@ubuntu:~# ip addr sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 link/ether 00:0c:29:bc:fc:8b brd ff:ff:ff:ff:ff:ff inet6 fe80::20c:29ff:febc:fc8b/64 scope link valid_lft forever preferred_lft forever root@ubuntu:~# ip route sh root@ubuntu:~# ip link add link eth0 eth0.1 addr 00:00:00:00:00:11 type macvlan root@ubuntu:~# ip link add link eth0 eth0.2 addr 00:00:00:00:00:22 type macvlan root@ubuntu:~# ip link add link eth0 eth0.3 addr 00:00:00:00:00:33 type macvlan root@ubuntu:~# ip -4 link sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 link/ether 00:0c:29:bc:fc:8b brd ff:ff:ff:ff:ff:ff 18: eth0.1@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/ether 00:00:00:00:00:11 brd ff:ff:ff:ff:ff:ff 19: eth0.2@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/ether 00:00:00:00:00:22 brd ff:ff:ff:ff:ff:ff 20: eth0.3@eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default link/ether 00:00:00:00:00:33 brd ff:ff:ff:ff:ff:ff root@ubuntu:~# ip -4 addr sh 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever root@ubuntu:~# ip -4 route sh root@ubuntu:~# dhclient -v eth0.1 Internet Systems Consortium DHCP Client 4.2.4 Copyright 2004-2012 Internet Systems Consortium.

  • Has anyone used the sharedband connection bonding product?

    - by John Rennie
    See http://www.sharedband.com/ for details on the product. Obviously Sharedband aren't too keen on giving away their technical secrets, but I would guess that it bonds the connections at the IP layer i.e. their routers send the IP packets to the SharedBand routers over all available lines and the ShareBand routers handle all the virtual circuitry and provide the NATing to whatever IP address(es) they've assigned you. It looks a clever idea, and a good way to provide some resilience over ADSL links. You can even use ADSL links from different ISPs and SharedBand will still bond them for you. But, I find myself wondering how well it really works, and whether it's worth it. The Draytek routers can already load balance (though not bond) up to four ADSL lines, so the SharedBand product really only offers an advantage if you're hosting servers i.e. you can have one IP address to accept incoming connections through all your (working) ADSL lines. But should you really try and host servers using ADSL lines, especially since ADSL upload performance isn't stellar? Wouldn't it be better to use a hosted server, or maybe pay up for a leased line with a SLA? So I'm asking if anyone is using SharedBand, and if so what do you think of it? JR

  • nginx terminates connection after 65k bytes

    - by David Wolever
    I've got nginx configured as a front-end to a Python application running under gunicorn, but nginx is terminating connections after about 65k of data have been sent. For example, I've got a view which looks like this: def debug_big_file(request): return HttpResponse("x" * 500000) But when I access that URL through nginx, I only get 65283 bytes: $ curl https://example.com/debug/big-file | wc … curl: (18) transfer closed with outstanding read data remaining 0 1 65283 Note that everything works as expected when accessing gunicorn directly: $ curl http://localhost:1234/debug/big-file | wc … 0 1 500000 The relevant nginx config: location / { proxy_pass http://localhost:1234/; proxy_redirect off; proxy_headers_hash_bucket_size 96; } And nginx version 1.7.0 Some other facts: The number of bytes is consistent from request to request, but it varies based on the content (I first noticed it with a large PNG file, which was cut off after 65,372 bytes, not 65,283) 110k bytes are sent correctly (ie, "x" * 110000 returns all 110,000 bytes), but 120k bytes are not tcpdump suggests that nginx is sending a RST packet to gunicorn:

  • Software for failover across multiple external hosts

    - by Lin
    I have multiple webservers with the same content, hosted across different providers. However, I can't seem to find a nice, simple failover solution. Load-balancing software (Pound, HAProxy, etc.) are unnecessary, and I need the flexibility to manage over 100+ domains, so the paid DNS failover solutions I've found are too expensive. So far the simplest solution I've thought of is just to set a very low TTL (30min - 1hr) in each zone entry on my nameservers (running BIND). Then, continuously monitor each server, and temporarily remove failed servers from zone entries. But this seems like something that should be currently available. I only have root access to different VPSes running CentOS. Any suggestions? Thanks!

  • sSMTP Unable to send message using external mail server SMTP

    - by OrangeGrover
    I'm trying to finish up my Nagios install by having it email me. It was emailing me using /bin/mail so it always got sent to my spam folders. I installed sSMTP to try to send a request to my work's email server to be able to send out a message from an authenticated user. Here is my /etc/ssmtp/ssmtp.conf file: mailhub=10.200.120.148:25 UseTLS=NO AuthUser= [email protected] AuthPass=PASSWORD So far I've been using the following command, and it will still arrive to my email inbox as root@localhost which causes it to go to my spam folder (with the exception of one email provider I have). cat message |ssmtp [email protected] I've looked at a few examples online, and they all seem to have pretty much the same as me. Does anybody see the any mistakes that I'm making? Just to clarify, [email protected] is a user on the mail server that my work uses.

  • Network connection to Firebird 2.1 became slow after upgrading to Ubuntu 10.04

    - by lyle
    We've got a setup that we're using for different clients : a program connecting to a Firebird server on a local network. So far we mostly used 32bit processors running Ubuntu LTS (recently upgraded to 10.04). Now we introduced servers running on 64bit processors, running Ubuntu 10.04 64bit. Suddenly some queries run slower than they used to. In short: running the query locally works fine on both 64bit and 32bit servers, but when running the same queries over the network the 64bit server is suddenly much slower. We did a few checks with both local and remote connections to both 64bit and 32bit servers, using identical databases and identical queries, running in Flamerobin. Running the query locally takes a negligible amount of time: 0.008s on the 64bit server, 0.014s on the 32bit servers. So the servers themselves are running fine. Running the queries over the network, the 64bit server suddenly needs up to 0.160s to respond, while the 32bit server responds in 0.055s. So the older servers are twice as fast over the network, in spite of the newer servers being twice as fast if run locally. Apart from that the setup is identical. All servers are running the same installation of Ubuntu 10.04, same version of Firebird and so on, the only difference is that some are 64 and some 32bit. Any idea?? I tried to google it, but I couldn't find any complains that Firebird 64bit is slower than Firebird 32bit, except that the Firebird 2.1 change log mentions that there's a new network API which is twice as fast, as soon as the drivers are updated to use it. So I could imagine that the 64bit driver is still using the old API, but that's a bit of a stretch, I guess. Thanx in advance for any replies! :)

  • Diagnose Issues with USB External Hard Drive

    - by Chris Lieb
    I have a 1TB SATA hard drive in a third-party USB enclosure hooked up to my computer via USB. The drive has become increasingly unreliable, randomly unmounting and remounting in Windows, making strange noises on occasion, and every once in a while making lots of noise and then unmounting, only fixable by powering down the enclosure, waiting a while, then powering it back up again. I am unsure if the hard drive or the enclosure is to blame. The random unmount/remount could be the enclosure, but the strange sounds are likely related to the hard drive. Given this uncertainty, I want to figure out which of the two items needs to be replaced. However, I do not know of a way to test each item separately since I do not have an extra SATA-to-USB enclosure to test the hard drive with or an extra SATA hard drive to test the enclosure with. Does anyone know how to figure out what's to blame so that I don't have to replace both unless it is absolutely necessary.

  • KVM-Guests can't get past bridge - no internet connection

    - by tmn29a
    I'm running a backported KVM on a Debian Squeeze. ATM the KVM-Guest can't connect to the internet through the bridge I have set up. The guests can reach each other, the host but nothing outside. I can neither ping, nslookup or do anything to a remote address. The guest are configured to have a static IP. When I didn;t have the bridge but a virtual bridge (the KVM-default) the guest could connect fine. After setting up the bridge things broke, so I think the problem lies there. # The loopback network interface auto lo br0 iface lo inet loopback # Bonding Interface auto bond0 iface bond0 inet static address 10.XXX.XXX.84 netmask 255.255.255.192 network 10.XXX.XXX.64 gateway 10.XXX.XXX.65 slaves eth0 eth1 bond_mode active-backup bond_miimon 100 bond_downdelay 200 bond_updelay 200 iface br0 inet static bridge_ports eth0 eth1 address 172.xxx.xxx.65 broadcast 172.xxx.xxx.127 netmask 255.255.255.192 gateway 172.xxx.xxx.65 bridge_stp on bridge_maxwait 0 Thanks in advance for your help !

  • Managing Many External Hosts Using EC2 and Route 53

    - by futureal
    Looking for a "best practice" answer to managing externally-addressable hosts using the combination of Amazon EC2 and Amazon Route 53, without using Elastic IPs for each host. In my scenario I will have 30+ hosts that need to be accessible from outside EC2, so directly using internal DNS will not work. In the past, I have addressed hosts by assigning an elastic IP to that host (let's say, 55.55.55.55) and then creating an associated A record. For example, let's say I want to create "ec2-corp01.mydomain.com" I might do: ec2-corp01.mydomain.com. A 55.55.55.55 300 Then on that EC2 instance, I would assign the Elastic IP of 55.55.55.55, and everything works fine. Of course, to make this work, I need to have one Elastic IP per instance, which is something I'd like to avoid if possible; I'd like the infrastructure to be more dynamic. So my thought is to try something like: Create a script that queries the internal EC2 tools to determine an instance's private hostname On instance boot, call that script to determine its hostname, and then using the command-line Route 53 interface to find and update that hostname to its current internal hostname Since the host will have a relatively low TTL (let's say 300 as above, or 5 minutes) it should take effect pretty quickly Is this a good idea? Is there a better or more widely accepted way to handle it? If it IS a good idea, what type of record should I be creating? A CNAME that points to the internal host, like ec2-55-55-55-55.compute-1.amazonaws.com? Is an A record better or worse? Thanks!

  • Amazon AWS Ec2 instance, Elastic IP, Domain name from external domainseller, and Google Apps for Email

    - by Sid
    We are hosting our site on an Ec2 instance. Our Elastic IP is w.x.y.z and Public DNS is: ec2-w-x-y-z.compute-1.amazonaws.com. We've bought a domain name domainname.com from a lesser known domain-name-seller. We added an A-record pointing domainname.com to w.x.y.z. Will this work or do we need a CNAME record to point to the same too? We wanted to use Google apps for emailing so adjusted the TXT/MX records according to the Google Apps instructions to be able to send/recv email using @domainname.com email addresses. Have we got it right, more important, we came across queries relating to email sent from ec2-w-x-y-z.compute-1.amazonaws.com (our users can send email from their onsite accounts) going to spam (rDNS not pointing to domainname.com but to ec2-w-x-y-z.compute-1.amazonaws.com). How can we fix this? We came across SPF records, do they provide a complete solution? We aren't sure as to how to use them. Can you help pls? Thank you, Sid

  • Create tunnel through an open SSH connection?

    - by criptych
    I have a remote PC (behind NAT and firewall) set up to create a reverse SSH tunnel to my home PC/server (DMZed). Unfortunately, the tunnel hasn't been working lately. Fortunately -- I think -- the remote PC currently has an SFTP session open to the local one. My question is, can I create a tunnel back to the remote PC through that session? Or am I SOL until I can physically get in to restore the reverse tunnel on the remote PC?

  • Connection issues with Linksys WRT54GL / Tomato

    - by Phoshi
    So I recently purchased a new router, and decided to put Tomato on it for some of the fancy features, like graphs. Only problem is, now I've installed it I can't connect to the internet any more! What I've done so far is plug the router in, connect to it wirelessly, and upgrade the firmware to the right version for my router. This went swimmingly, the router restarted, and everything's Tomatoey. Except it won't, now, connect to the internet, and I'm entirely unsure what I've missed. My old router was a BT Homehub, my ISP is BT (British Telecommunications). I'm a bit lost, this is the first time I've done any of this 3rd party firmware stuff.

  • MSFT Excel pivot table links to external data

    - by dreftymac
    Question1: What is the best online forum to ask MSFT Excel questions of the following variety? Question2: How can I link an excel pivot-table to a potentially changing source table without having to re-draw the excel pivot-table layout every time the source table changes data. (Note, the columns are not changing, just the data in the rows). Background: I have an excel 2007 pivot table that is grabbing data from another sheet (an excel "table" ... tables are a new feature of excel 2007). When I change the data in the source table, and then go to the pivot table and press "refresh" ... the pivot table reverts to its "blank" format and requires me to re-drag the columns rows and values. What I want is for the pivot-table to simply re-draw itself without me having to re-create the pivot table layout.
