• Cannot Start MySQL Server on Fresh MAMP Install

  - by alexpelan

  I'm using Mac OS X 10.6.2 on my Macbook Pro. I can get the apache server to start, but not the mysql server, on both the default apache and default MAMP ports. When I try to go to my start page, I get the message "Error: Could not connect to MySQL server!" .

• Expert iptables help needed?

  - by Asad Moeen

  After a detailed analysis, I collected these details. I am under a UDP Flood which is more of application dependent. I run a Game-Server and an attacker is flooding me with "getstatus" query which makes the GameServer respond by making the replies to the query which cause output to the attacker's IP as high as 30mb/s and server lag. Here are the packet details, Packet starts with 4 bytes 0xff and then getstatus. Theoretically, the packet is like "\xff\xff\xff\xffgetstatus " Now that I've tried a lot of iptables variations like state and rate-limiting along side but those didn't work. Rate Limit works good but only when the Server is not started. As soon as the server starts, no iptables rule seems to block it. Anyone else got more solutions? someone asked me to contact the provider and get it done at the Network/Router but that looks very odd and I believe they might not do it since that would also affect other clients. Responding to all those answers, I'd say: Firstly, its a VPS so they can't do it for me. Secondly, I don't care if something is coming in but since its application generated so there has to be a OS level solution to block the outgoing packets. At least the outgoing ones must be stopped. Secondly, its not Ddos since just 400kb/s input generates 30mb/s output from my GameServer. That never happens in a D-dos. Asking the provider/hardware level solution should be used in that case but this one is different. And Yes, Banning his IP stops the flood of outgoing packets but he has many more IP-Addresses as he spoofs his original so I just need something to block him automatically. Even tried a lot of Firewalls but as you know they are just front-ends to iptables so if something doesn't work on iptables, what would the firewalls do? These were the rules I tried, iptables -A INPUT -p udp -m state --state NEW -m recent --set --name DDOS --rsource iptables -A INPUT -p udp -m state --state NEW -m recent --update --seconds 1 --hitcount 5 --name DDOS --rsource -j DROP It works for the attacks on un-used ports but when the server is listening and responding to the incoming queries by the attacker, it never works. Okay Tom.H, your rules were working when I modified them somehow like this: iptables -A INPUT -p udp -m length --length 1:1024 -m recent --set --name XXXX --rsource iptables -A INPUT -p udp -m string --string "xxxxxxxxxx" --algo bm --to 65535 -m recent --update --seconds 1 --hitcount 15 --name XXXX --rsource -j DROP They worked for about 3 days very good where the string "xxxxxxxxx" would be rate-limited, blocked if someone flooded and also didn't affect the clients. But just today, I tried updating the chain to try to remove a previously blocked IP so for that I had to flush the chain and restore this rule ( iptables -X and iptables -F ), some clients were already connected to servers including me. So restoring the rules now would also block some of the clients string completely while some are not affected. So does this mean I need to restart the server or why else would this happen because the last time the rules were working, there was no one connected?

• Add a small RAID card? Will it help overall stability and performance of my nine hard drives?

  - by Ray

  Hi, Will I get any extra genuine added performance and RAID stability if I insert a basic RAID card into a PCI-E x1 slot? I am considering the Adaptec 1220SA - 2 port SATA , pci-express (1x) , raid 0/1. Ok it only supports two SATA drives. Purpose is to help support the eight internal hard drives (1TB each), a DVD drive and an external e-SATA connected 2TB hard drive - by dealing with two of the internal hard drives. My current configuration of eight internal 1TB Barracuda (7200.12) SATA hard drives, one external 2TB SATA Western Digital Green Drive (e-SATA) and one DVD drive can already be supported by the Intel P55 & JMicron controllers on the ASUS motherboard : the Intel P55 (controls six HDD; configured as three x RAID 1), and the JMicron (controls two HDD as one RAID 1, as well as the DVD drive and the external SATA drive via the motherboard's e-SATA port (controlled by the JMicron)). Bigger picture details : I have an ASUS motherboard designed for the LGA1156 type processor and it includes the Intel P55 Express Chipset and JMicron. I am using the Intel Core i7-870 processor, and have 8GB DDR3 (1333) memory (four x 2GB Corsair DIMMs). Enough overall power. The power supply is more than sufficicient for the system. Corsair AX850. The system will never need the full 850 watts (future : second graphics card). The RAID card would provide hardware RAID 1 for two of the eight intrnal drives. It would either reduce the load on : the Intel P55 firmware RAID support, or replace the JMicron controller's RAID 1 set. I am busy installing the above configuration using Windows 7 Ultimate 64-bit as the OS. The RAID card is a last minute addition to the plan. Is it worth spending the extra R700 - R900 on the Adaptec 1220SA, or equivalent RAID card? I cannot afford to spend yet another R2000 - R3000 on a RAID card that would support many SATA2 hard drives, with a better RAID, example the RAID 5. My Issue & assumption : I am trusting that the Intel P55 chipset can properly handle six drives, configured as three * RAID 1. I am assuming that the JMicron can handle, using its RED SATA ports, one RAID-1 (two HDDs). The DVD drive connects to the JMicron optical SATA port 1 (white port 1). White port 2 is not used. The e-SATA connection is from the JMicron straight to, and through the motherboard - to an on-board (rear panel) e-SATA port. Am I being a little hopeful in only using the on-board Intel P55 and the JMicron? Is it a waste of money to install a RAID card that handles two SATA2 drives? OR Is it wisdom to take the pressure a little off the Intel P55? Obviously I am interested in data security, hence RAID 1, not RAID Zero. RAID 5 would be nice. The CPU, Intel Core i7-870 will provide the clout. Context to nine drives : I am using virtualisation with Windows 7 Ultimate. Bootable VMs. The operating system gets a mirror. Loaded apps gets a mirror. The current design data is kept in another mirror and Another mirror is back-up one and / or VM territory. Then the external 2TB drive (via e-SATA) is the next layer of data security and then finally, I use off-site data security. Thanks.

• phpmyadmin login redirect fails with custom ssl port

  - by baraboom

  The server is running Ubuntu 10.10, Apache 2.2.16, PHP 5.3.3-1ubuntu9.3, phpMyAdmin 3.3.7deb5build0.10.10.1. Since this same server is also running Zimbra on port 443, I've configured apache to serve SSL on port 81. So far, I have one CMS script running on this virtual host successfully. However, when I access /phpmyadmin (set up with the default alias) on my custom ssl port and submit the login form, I am redirected to http://vhost.domain.com:81/index.php?TOKEN=foo (note the http:// instead of the https:// that the login url was using). This generates an Error 400 Bad Request complaining about "speaking plain HTTP to an SSL-enabled server port." I can then manually change the http:// to https:// in the URL and use phpmyadmin as expected. I was annoyed enough to spend an hour trying to fix it and now even more annoyed that I cannot figure it out. I've tried various things, including: Adding $cfg['PmaAbsoluteUri'] = 'https://vhost.domain.com:81/phpmyadmin/'; to the /usr/share/phpmyadmin/config.inc.php file but this did not correct the problem (even though /usr/share/phpmyadmin/libraries/auth/cookie.auth.lib.php looks like it should honor it and use it as the redirect). Adding $cfg['ForceSSL'] = 1; to the same config.inc.php but then apache spirals into an infinite redirect. Adding a rewrite rule to the vhost-ssl conf file in apache but I was unable to figure out the condition to use when http:// was present along with the correct ssl port of :81. Lots of googling. Here are the relevant Apache configuration pieces: /etc/apache2/ports.conf <IfModule mod_ssl.c> NameVirtualHost *:81 Listen 81 </IfModule> /etc/apache2/sites-enabled/vhost-nonssl <VirtualHost *:80> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}:81%{REQUEST_URI} </Virtualhost> /etc/apache2/sites-enabled/vhost-ssl <VirtualHost *:81> ServerAdmin webmaster@localhost ServerName vhost.domain.com DocumentRoot /home/xxx/sites/vhost/html <Directory /> Options FollowSymLinks AllowOverride None AuthType Basic AuthName "Restricted Vhost" AuthUserFile /home/xxx/sites/vhost/.users Require valid-user </Directory> <Directory /home/xxx/sites/vhost/html/> Options -Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> /etc/apache2/conf.d/phpmyadmin.conf Alias /phpmyadmin /usr/share/phpmyadmin (The rest of the default .conf truncated.) Everything in the apache config seems to work ok - the rewrite from non-ssl to ssl, the http authentication, the problem only happens when I am submitting the login form for phpmyadmin from https://vhost.domain.com:81/index.php. Other configs: The phpmyadmin config is completely default and the php.ini has only had some minor changes to memory and timeout limits. These seem to work fine, as mentioned, another php script runs with no problem and phpmyadmin works great once I manually enter in the correct schema after login. I'm looking for either a bandaid I can add to save me the trouble of manually entering in the https:// after login, a real fix that will make phpmyadmin behave as I think it should or some greater understanding of why my desired config is not possible.

• Outlook 2013 keeps freezing, semi-consistently

  - by AviD

  I have an oddity of problem with my Outlook's stability. It seems to be freezing up, not at random intervals, but based on a seemingly strange combination of configurations. I have been trying many different combinations, I've even devolved to "Cargo-cult" debugging, since I have no clue what is causing this... Here is my set up - since I don't know for sure which settings are causing the lockup, I'll probably mention irrelevant things: (relatively) clean install of Windows 8 (on hyper-v, if that matters) Clean install of Outlook 2013, fully updated 3 accounts configured: Hotmail account configured with ActiveSync Gmail account Large-ish account (several GB) connected with IMAP Only a few folders are subscribed in IMAP Outlook is set to only display subscribed folders configured to keep messages permanently Google Apps account, connected with IMAP Small account connected with IMAP All folders IMAP subscribed Outlook is set to only display subscribed folders configured to keep messages permanently Several Send/Receive Groups configured, to try different configurations of enabling/disable/partial the different accounts - with different send times, from 60 minutes down to 5 minutes. The problem is that at certain points Outlook completely freezes up and I have to kill it. This is not consistent - there are some things that cause it immediately almost consistently, there are some times that it just happens by itself after some period of time (sometimes a few moments, sometimes a few hours; sometimes while using it, sometimes after I've been away from it for a few hours). I have searched all over, and there seem to be many with similar (apparently) problem, and found numerous "solutions" (some even more cargocultish than mine), but so far none of them worked. I've removed all the accounts, both all together and one at a time, and re-configured them - eventually it freezes up. I've tried uninstalling Outlook, cleaning it up completely - removing files, app settings, registry keys, etc - then reinstalling - eventually it freezes up. I've only enabled the Hotmail account, disabling (but not removing) the Google accounts - apparently this does not lock up. I've enabled the Hotmail and the Gmail accounts, leaving the Apps one disabled - it seems like it does not lock up. With all accounts enabled, it locks up almost immediately after doing a send/receive. With only the Apps account enabled, it seems to not lock up. With the Hotmail and the Apps accounts enabled (Gmail disabled), it seems like it locks up after a random amount of time. With Hotmail enabled, and Gmail and Apps both enabled but set to receive only custom folder downloading (not all subscribed folders) - sometimes it locks up right after a send/receive, sometimes it goes for hours without locking up, and sometimes it only locks up when I send an email. I've tried switching the ports for the Google accounts (SSL/465 vs TLS/587), though I have no idea if this should affect, but no real difference. In short, I honestly have no idea what is actually causing Outlook to lock up, I might be completely barking up the wrong tree. At this point I don't really know what else to try, I'm flipping switches at random here. I would like to have all 3 accounts enabled, ideally in several groups (e.g. pull down only important folders in a group with short interval, and all other folders in a longer interval) - obviously without freezing up at all. I've tried putting in all the important details, if there is anything else important to add please let me know. Another issue that occurred to me might also be connected - the Google accounts don't always synchronize properly, even after a send/receive or "update folder". At least not consistently... though I haven't been able to find a significant connection between this and that.

  I would like to install bonding with 4 links with mode 4. but only "download/receiving" works with bondig. for transmitting the system chooses one link. ifconfig bond0 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 inet addr:ip Bcast:ip Mask:255.255.255.248 inet6 addr: fe80::92e2:baff:fe0f:76b4/64 Scope:Link UP BROADCAST RUNNING MASTER MULTICAST MTU:1500 Metric:1 RX packets:239187413 errors:0 dropped:10944 overruns:0 frame:0 TX packets:536902370 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:14688536197 (13.6 GiB) TX bytes:799521192901 (744.6 GiB) eth2 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:54969488 errors:0 dropped:0 overruns:0 frame:0 TX packets:2537 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3374778591 (3.1 GiB) TX bytes:314290 (306.9 KiB) eth3 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:64935805 errors:0 dropped:1 overruns:0 frame:0 TX packets:2532 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3993499746 (3.7 GiB) TX bytes:313968 (306.6 KiB) eth4 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:57352105 errors:0 dropped:2 overruns:0 frame:0 TX packets:536894778 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3524236530 (3.2 GiB) TX bytes:799520265627 (744.6 GiB) eth5 Link encap:Ethernet HWaddr 90:E2:BA:0F:76:B4 UP BROADCAST RUNNING SLAVE MULTICAST MTU:1500 Metric:1 RX packets:61930025 errors:0 dropped:3 overruns:0 frame:0 TX packets:2540 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3796021948 (3.5 GiB) TX bytes:314274 (306.9 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:62 errors:0 dropped:0 overruns:0 frame:0 TX packets:62 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:5320 (5.1 KiB) TX bytes:5320 (5.1 KiB) those are my configs: DEVICE="eth2" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE="eth3" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE="eth4" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE="eth5" BOOTPROTO="none" MASTER=bond0 SLAVE=yes USERCTL=no NM_CONTROLLED="no" ONBOOT="yes" DEVICE=bond0 IPADDR=<ip> BROADCAST=<ip> NETWORK=<ip> GATEWAY=<ip> NETMASK=<ip> USERCTL=no BOOTPROTO=none ONBOOT=yes NM_CONTROLLED=no cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: IEEE 802.3ad Dynamic link aggregation Transmit Hash Policy: layer2 (0) MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 0 Down Delay (ms): 0 802.3ad info LACP rate: slow Aggregator selection policy (ad_select): stable Active Aggregator Info: Aggregator ID: 1 Number of ports: 4 Actor Key: 17 Partner Key: 11 Partner Mac Address: 00:24:51:12:63:00 Slave Interface: eth2 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b4 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth3 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b5 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth4 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b6 Aggregator ID: 1 Slave queue ID: 0 Slave Interface: eth5 MII Status: up Speed: 1000 Mbps Duplex: full Link Failure Count: 0 Permanent HW addr: 90:e2:ba:0f:76:b7 Aggregator ID: 1 Slave queue ID: 0 /etc/modprobe.d/bonding.conf alias bond0 bonding options bond0 mode=4 miimon=100 updelay=200 #downdelay=200 xmit_hash_policy=layer3+4 lacp_rate=1 Linux: Linux 3.0.0+ #1 SMP Fri Oct 26 07:55:47 EEST 2012 x86_64 x86_64 x86_64 GNU/Linux what i've tried: downdelay=200 xmit_hash_policy=layer3+4 lacp_rate=1 mode 6

• udp through nat

  - by youllknow

  Hi everyone! I've two private networks (each of them behind a typical dsl router). The routers are connected to the WWW. The extern interface of each router have one dynamic IP address. I want to stream data via UDP directly between one client in private network A and one client in private network B. I've already tried a lot of things (see: http://en.wikipedia.org/wiki/UDP_hole_punching, or STUN). But it wasn't possible for me to transfer data between the two clients. It's possible to use a server (located in the WWW, with static IP) to transfer the extern IPs (and extern ports) from the routers between the clients. So imagine client A knows client B's external IP and client B's external port assigned by his router. I simply tried sending UDP packet to the receivers external IP/port combination, but without any result. So does anyone know what do to communicate via UDP throw the two NAT routers? It must be possible??? Or does Skype, for example, not directly communicate between the clients when the call eachother (voice over ip). I am sorry for my bad English! If something is confusing don't mind asking me!!! Thanks for your help in advance. ::::EDIT:::: I can't get pwnat or chownat working. I tried it with my own dsl-gateway - didn't work. Then I set up a complete virtual environment using VMWare. C1 (Client 1, WinXP Prof SP3): 172.16.16.100/24, GW 172.16.16.1 C2 (Client 2, WinXP Prof SP3): 10.0.0.100/24, GW 10.0.0.1 C3 (Client 3, WinXP Prof SP3): 3.0.0.2/24, GW 3.0.0.1 S1 (Ubuntu 10.04 x64 Server): eth0: 172.16.16.1/24, eth1: 1.0.0.2/24 GW 1.0.0.1 S2 (Ubuntu 10.04 x64 Server): eth0: 10.0.0.1/24, eth1: 2.0.0.2/24 GW 2.0.0.1 S3 (Ubuntu 10.04 x64 Server): eth0: 1.0.0.1/24, eth1: 2.0.0.1/24, eth2: 3.0.0.1/24 +--+ +--+ +--+ +--+ +--+ |C1|-----|S1|-----|S3|-----|S2|-----|C2| +--+ +--+ +--+ +--+ +--+ | +--+ |C3| +--+ Server S1 and S2 provide NAT functionality. (they have routing enabled and provide a firewall, which allows trafic from the internal net and provide the nat functionality) Server S3 has routing enabled. The client firewalls are turned off. C1 and C2 are able to ping C3, e.g. visit C3's webserver. They are also able to send UDP Packets to C3 (C3 successful receives them)! C1 and C2 have also webservers running for test reasons. I run ""chownat -s 80 2.0.0.2"" at C1, and ""chownat -c 8000 1.0.0.2"" at C2. Then I tried to access the Webpage from C1 via webbrower localhost at port 8000. It didn't work. Can anybody help me? Any suggestions? If you have any questions to my question, please ask!

• OpenVPN on Tomato and Vista - can't see my network

  - by Ian

  I followed the instructions here (http://todayguesswhat.blogspot.ca/2011/03/quick-simple-vpn-setup-guide-using.html) to set up a TCP connection to OpenVPN on my Tomato router. Used TCP because the place I usually surf at seems to have the other ports blocked. My Vista laptop is able to connect to the router but I don't appear to be getting an IP address. I'm able to access my router's admin page, but I can't see the network at home. When I browse to Whatsmyip I see my home IP. Here are the results of route print -4 when I'm just connect to the library and when I've fired up the VP connection as well: Library only: =========================================================================== Interface List 22 ...00 ff c4 a0 e7 5c ......

• Ubuntu 14.04, OpenLDAP TLS problems

  So i have set up an openldap server using this guide here. It worked fine. But as i want to use sssd i also need TLS to be working for ldap. So i looked into and followed the TLS part of the guide. And i never got any errors and slapd started fine again. BUT.

• iCloud stuff stops working while connected to OpenVPN

  - by Taco Bob

  I have a fairly simple OpenVPN setup on an OpenVZ VPS with Ubuntu 11.10. Client is the Viscosity client on Mac OS X 10.8.2, and after some testing, we can rule out the client as being part of the problem. Everything has been working fine except for Apple's iCloud stuff. Web surfing, email, FTP, NNTP, and Skype are all working as expected. It's ONLY the iCloud services that cease to function. If I connect to the VPN, iCloud stuff stops working. I no longer get anything in Messages, Calendar items don't get updated, and Notifications stop working. If I disconnect, the iCloud stuff all starts working. Connect again, iCloud stops working. Here's the server.conf: status openvpn-status.log log /var/log/openvpn.log verb 4 port 1194 proto udp dev tun ca /etc/openvpn/ca.crt cert /etc/openvpn/server.crt key /etc/openvpn/server.key dh /etc/openvpn/dh1024.pem server 10.9.8.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "redirect-gateway def1" push “dhcp-option DNS 10.9.8.1? keepalive 10 120 duplicate-cn cipher BF-CBC comp-lzo user nobody group nogroup persist-key persist-tun tun-mtu 1500 mssfix 1400 I'm using iptables in a script, and it's also fairly simplistic. iptables -F iptables -t nat -F iptables -t mangle -F iptables -A FORWARD -i tun0 -o venet0 -j ACCEPT iptables -A FORWARD -i venet0 -o tun0 -j ACCEPT iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -p tcp --dport 1194 -j ACCEPT iptables -A INPUT -p udp --dport 1194 -j ACCEPT iptables -t nat -A POSTROUTING -s 10.9.8.0/24 -j SNAT --to-source <server's public ip> echo 1 > /proc/sys/net/ipv4/ip_forward I tried forwarding ports as well, with no success. iptables -A FORWARD -p tcp -d 10.9.8.0/24 --dport 5222:5230 -j ACCEPT iptables -t nat -A PREROUTING -p tcp --dport 5222:5230 -j DNAT --to-destination 10.9.8.6 I am also sometimes behind a double-NAT situation that I have no control over. Client -> work VPN -> my OpenVPN box -> Internet. Client -> Airport Express -> ISP (which is doing NAT) -> my OpenVPN box -> Internet. Those two situations are just the fact of life where I am, and I cannot change them. I do have full control over my client and the OpenVPN server. I am completely out of ideas. I have posted a similar query at the OpenVPN forums, but it hasn't posted yet and seems to be in their moderation queue still. Tried on freenode irc channels, but nobody is awake, so here I am. I have Googled extensively for this, and can find nothing that is related. Help me get iCloud stuff working again! (I tried serverfault, it was closed as off-topic. I'm trying here and the Unix site as well. Here because it's a more general audience that might know more about OpenVPN based on the number of questions I see asked about it) EDIT: -I have also tried upgrading to Version: 2.3-beta1-debian0 - issue persists. -Removed all iptables rules except for the ones that flush -left this rule:iptables -t nat -A POSTROUTING -s 10.9.8.0/24 -j SNAT --to-source (server ip) -added iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT still, nothing works.

We (our company) are planning to deploy Symantec Endpoint Protection and Symantec Desktop Recovery 2011 Desktop Edition to our 3000 - 4000 workstations (Windows7 32 and 64) with a few 100s with Windows XP 32/64 Bit. I have read the implementation guide for SEP and have read tech-notes for Desktop Recovery 2011. Our team have planned to deploy this as follows : 1 x dedicated SQL 2008R2 for Symantec Endpoint Protection (Instead of using the Embedded Database) 1 x Dedicated SQL 2008R2 for Symantec Desktop Recovery 2011 (Instead of using the Embedded Database) 1 x Dedicated W2K8 R2 Box for the SEPM (Symantec Endpoint Protection Manager - Mgmt. APP) 1 x Dedicated W2K8 R2 Box for the Symantec Desktop Recovery 2011 Management Application Agent Deployment : As per Symantec Documentation for both of the above, an agent can be pushed via the Mgmt. Application (provided no firewalls are blocking ports required etc. - we have Windows firewall disabled already). Server Hardware : Per SQL Server : 16GB RAM + SAS DISKS + Dual XEON, RAID-10 for the SQL DB or I can always mount a LUN from our existing Hitachi or EMC SAN. SEPM Server : 16GB RAM + SAS DISKS + DUAL XEON System Recovery MGMT SERVER : 16GB RAM + SAS DISKS + DUAL XEON Above is the initial plan we have for 3000 - 4000 client workstation (Windows) Now my Questions :-) a) If we had these users distributed amongst two sites with AD DC / GC in each site, How would I restrict SEPM and Desktop Mgmt. solution to only check for users in their respective site ? b) At present all users are under one building but we are going to move some dept. to a new location (with dedicated connectivity), How would we control which SEPM / MGMT Server is responsible for which site ? c) We have netbackup in our environment backing up other servers, I am planning to protect these 4 (2 x SQL, 1 x SEPM, 1 x System Recovery Mgmt. Server) via netbackup or I can use System recovery 2011 server edition on all 4 of these boxes as well. (License is not an issue as we have the complete symantec portfolio included in our license). d) Now - Saving Desktop backups - What strategies have you implemented ? Any best practice recommendation for a large user base ? I was thinking to either mount a LUN from our Hitachi SAN on the Symantec Recovery Server itself or backup to the users hard drive locally and then copy it over to a network location ? Suggestions welcome :-) If you have anything to add / correct - that will be really helpful before diving into the actual implementation phase. Will be most grateful with your suggestions, recommendations and corrections with above - Many Thanks !

• Bind9 Debian Not responding

  - by Marc

  Im trying to set up a webserver with Bind9, apache2 on Debian 6. I am trying to learn to do it manualy so I do not have any control panels or anything just the command line. I have a domain name lets call it www.example.com I want a virtual host setup so that I can have multiple websites with different names on my server. I have ns1.example.com and ns2.example.com registered at my servers IP (123.456.789.12). Below is my Bind9 named.conf.options options { directory "/var/cache/bind"; // If there is a firewall between you and nameservers you want // to talk to, you may need to fix the firewall to allow multiple // ports to talk. See http://www.kb.cert.org/vuls/id/800113 // If your ISP provided one or more IP addresses for stable // nameservers, you probably want to use them as forwarders. // Uncomment the following block, and insert the addresses replacing // the all-0's placeholder. // forwarders { // 0.0.0.0; // }; auth-nxdomain no; # conform to RFC1035 listen-on-v6 { any; }; }; This is the default I'm not sure if i was supposed to edit it. I didn't. Here is my named.conf.default-zones: // prime the server with knowledge of the root servers zone "." { type hint; file "/etc/bind/db.root"; }; // be authoritative for the localhost forward and reverse zones, and for // broadcast zones as per RFC 1912 zone "localhost" { type master; file "/etc/bind/db.local"; }; zone "127.in-addr.arpa" { type master; file "/etc/bind/db.127"; }; zone "0.in-addr.arpa" { type master; file "/etc/bind/db.0"; }; zone "255.in-addr.arpa" { type master; file "/etc/bind/db.255"; }; zone "example.com.com" { type master; file "etc/bind/example.com.db"; }; named.conf.local Is an empty file with a comment saying to do local configuration here. example.com.db looks like this: ; BIND data file for mywebsite.com ; $ORIGIN example.com. $TTL 604800 @ IN SOA ns1.example.com.

Now when i go to intodns I get: You should already know that your NS records at your nameservers are missing, so here it is again: ns1.example.com ns2.example.com Can someone help me? I'm not sure what Im doing wrong.

• Excessive denied requests for port 58322 in syslog

  - by Nathan C.

  My iptables is setup to block all unneeded ports as it should but I'm checking my syslog due to these random but all-to-frequent apache2 crashes and I noticed a lot of requests such as this. In all the archived syslogs that I have these are present from different IP addresses. There is a similar question with an accepted here: What service uses UDP port 60059?

• ISP 5 Device Limit ... again

  - by Tommo

  Sorry for the delay in responding to the suggestions that were posted in my first question (ISP 5 Device Limit - double NAT the solution?). I've been travelling and have not been able to try anything. Below is what I've tried and where I have not been successful. Any more help gratefully appreciated. I figure I need to give a more comprehensive overview of what I've got and how it's set up. First of all - I am using all Apple products here. I am iMac, iPad, iPhone, Apple TV, Airport Express and Time Capsule. I used to like the way that it 'just worked'. Now I find that it requires a bit of encouragement before it 'just works'. So, as I stated in my original question; my ISP has a router in my building that is limiting me to 5 devices. I am hard wired into this router and I can neither access it physically nor logically (they won't let me access it). Also, I only appear to be able to connect to it through the LAN ports on my Time Capsule. Any device I connect appears to be on a rolling IP list with the following settings: Router 91.72.80.1 Devices then get assigned IPv4 addresses in the range (as far as I can see) from 91.72.80.2 onwards. SubNet Mask 255.255.255.0 DNS Servers 213.132.63.25, 80.227.2.4 I have my Time Capsule / Router in Bridge-Mode which means I am limited to the 5 devices and cannot use Guest Networks etc. What I've tried today. Static IPs: On all devices, I went from DHCP to Static and put in the same information when they had connected using DHCP. Somewhat surprisingly this did not work. None of the devices enjoyed any connection to the router and certainly no internet connection. Intentional Double-NAT - Time Capsule to 'DHCP and NAT': By selecting DHCP and NAT on my Router I was able to connect devices to my Time Capsule in the range 10.0.1.2 to 10.0.1.200. This offered no internet connectivity and didn't really help the situation. In this mode, however, I was able to force the devices - individually and laboriously - to look for the Router and previously listed DNSs by inputting the numbers from 'Bridge-mode' into the STATIC settings and then resetting the connection. The Router then appeared to assign a distinct IP address to the device and it worked on the network. I had this working for more than 5 devices. However, this is not a great solution because as soon as one of the mobile devices left the building it needed repointing to the Router. The connections were also not very stable. Especially when trying to hold onto a VPN. Spoofing a few MAC addresses: I'm afraid I don't really know what this would achieve, nor how to do it on an Apple device… So … I'm almost back at Square One. I have had to withdraw to the Bridge-Mode position again with the 5 device limit to see if there's a better course of action to follow. ANY help would be much appreciated. I am positive that I cannot be the only one suffering under this 5 device limit!

• amplified reflected attack on dns

  - by Mike Janson

  The term is new to me. So I have a few questions about it. I've heard it mostly happens with DNS servers? How do you protect against it? How do you know if your servers can be used as a victim? This is a configuration issue right? my named conf file include "/etc/rndc.key"; controls { inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; }; }; options { /* make named use port 53 for the source of all queries, to allow * firewalls to block all ports except 53: */ // query-source port 53; /* We no longer enable this by default as the dns posion exploit has forced many providers to open up their firewalls a bit */ // Put files that named is allowed to write in the data/ directory: directory "/var/named"; // the default pid-file "/var/run/named/named.pid"; dump-file "data/cache_dump.db"; statistics-file "data/named_stats.txt"; /* memstatistics-file "data/named_mem_stats.txt"; */ allow-transfer {"none";}; }; logging { /* If you want to enable debugging, eg. using the 'rndc trace' command, * named will try to write the 'named.run' file in the $directory (/var/named"). * By default, SELinux policy does not allow named to modify the /var/named" directory, * so put the default debug log file in data/ : */ channel default_debug { file "data/named.run"; severity dynamic; }; }; view "localhost_resolver" { /* This view sets up named to be a localhost resolver ( caching only nameserver ). * If all you want is a caching-only nameserver, then you need only define this view: */ match-clients { 127.0.0.0/24; }; match-destinations { localhost; }; recursion yes; zone "."

• Unable to make the session state request to the session state server.

  - by Angry_IT_Guru

  For about 4-5 months now, I seem to be having this sporadic issue--mainly during our busiest time of the day between 10:30-11:45AM, where all my Windows 2003 web servers in a Microsoft NLB cluster start throwing session state server errors. A sample error is below. System.Web.HttpException: Unable to make the session state request to the session state server. Please ensure that the ASP.NET State service is started and that the client and server ports are the same. If the server is on a remote machine, please ensure that it accepts remote requests by checking the value of HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\aspnet_state\Parameters\AllowRemoteConnection. If the server is on the local machine, and if the before mentioned registry value does not exist or is set to 0, then the state server connection string must use either 'localhost' or '127.0.0.1' as the server name. at System.Web.SessionState.OutOfProcSessionStateStore.MakeRequest(StateProtocolVerb verb, String id, StateProtocolExclusive exclusiveAccess, Int32 extraFlags, Int32 timeout, Int32 lockCookie, Byte[] buf, Int32 cb, Int32 networkTimeout, SessionNDMakeRequestResults& results) at System.Web.SessionState.OutOfProcSessionStateStore.SetAndReleaseItemExclusive(HttpContext context, String id, SessionStateStoreData item, Object lockId, Boolean newItem) at System.Web.SessionState.SessionStateModule.OnReleaseState(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) Now I'm using ASP.NET State service on a centralized back-end Windows 2003 server that all servers communicate to. I was originally using SQL Server state for a couple years as well prior to having this issue. The problem with SQL wqas that when the issue occurred, it created a blocking situation which essentially impacted all users across all servers. The product company recommended that I use the standard ASP.NET State service as that was what they technically supported. Why this would make a difference is beyond me -- but I had no choice but to try it! I have attempted to create multiple application pools, adding additional servers, chaning TCP/IP timeout from 20 to 30 seconds, and even calling Microsoft ASP.NET product support, with very little success. I even recommended that they review whether they are using read-only session state instead of read/write per page request -- as I understand that this basically causes every page to make round-trips to state server even if state isn't being used on the page. Unfortunately, the application is developed by our product company and they insist that it is something with my environment because other clients do not have these sort of issues. However, I've talked to other clients and they tell me when they've seen issues like they, they've basically had to create another web farm. This issue almost seems like I've simply reached some architectural limit within the application... Microsoft's position on the issue is that the session state needs to be reduced and the returncode being reported back from the state server indicates buffers are full. To better understand the scope of issues (rather than wait for customers to call and complain), I installed ELMAH and configured it to send me e-mails when unhandled exceptions occur. I basically get 500-1000 e-mails during the time period of high activity! If any one has any other ideas I could try or better ways to troubleshoot, I'd appreciate it.

• Optimise Apache for EC2 micro instance

  - by Shiyu Sekam

  I'm running apache2 on a EC2 micro instance with ~600 mb RAM. The instance was running for almost a year without problems, but in the last weeks it just keeps crashing, because the server reached MaxClients. The server basically runs few websites, one wordpress blog(not often used), company website(most used) and 2 small sites, which are just internal. The database for the blog runs on RDS, so there's no Mysql running on this web server. When I came to the company, the server already was setup and is running apache + mod_php + prefork. We want to migrate that in the future to a nginx + php-fpm, but it still needs further testing. So for now I have to stick with the old setup. I also use CloudFlare DDOS protection in front of the server, because it was attacked a couple of the times in the last weeks. My company don't want to pay money for a better web server at this point, so I have to stick with the micro instance also. Additionally the code for the website we run is really bad and slow and sometimes a single page load can take up to 15 seconds. The whole website is dynamic and written in PHP, so caching isn't really an option here. It's a customized search for users.

• Windows 7 is stuck at "Starting Windows" when I attempt to boot computer

  - by Eli

  Basically, whenever I turn on my computer, it gets to the Starting Windows phase and just stays there. The startup animation still plays, yet it gets nowhere. I have tried booting into safe mode, however it gets stuck at loading CLASSPNP.SYS. It then freezes there and doesn't continue booting. I have tried booting into recovery mode from the hard drive, and it freezes after displaying the background image. I have tried booting from a recovery CD, which works, and I was able to use system restore. However, using system restore did not fix it, and it still is stuck at the Starting Windows screen. I have tried booting a Windows CD (Windows 8 Retail Installer) to see if I could upgrade it to fix this issue, however that froze at a blank screen after it got past the boot logo. I have tried changing around the BIOS settings (including resetting), to no avail. I have tried re-plugging the internal PSU cables (this is a custom-built desktop), yet this has changed nothing. I can boot into a loopback Ubuntu install on the same drive, which works fine, other than the fact that it has issues with some of the USB ports and the network card. This system has worked fine for the past few months, completely stable, and nothing in the configuration has changed before this error started happening. Startup Repair on the Windows recovery CD doesn't find any issues. Unplugging my secondary hard drive or swapping around memory doesn't change anything. The hard drive itself is fine, it hasn't shown any signs of failure and once again, boots my other OS fine. If anyone could help with this, that would be great. I can't seem to find any possible solution to this. If it makes any difference, my system specs are as follows: AMD FX-8320 Gigabyte GA-970A-D3 4GB of DDR3 Radeon HD 6870 550w PSU I'd like to not have to reinstall Windows, for I have more than a terabyte of data that I would have to back up if that becomes the only option. EDIT: I have since tried the following: Tried the solution involving restoring files from RegBackup, which changed nothing. Tried testing everything with Hiren's boot CD, everything comes back as fine. Tried disabling everything unnecessary in the BIOS and unplugging everything unneeded, it still hangs. Tried swapping out every possible combination of RAM, it still has the same result. The RAM is not at fault it seems Tried every GPU I own (which is many!) and it still hangs at the exact same place. Tried minimizing the power consumption as much as possible, even using an old PCI graphics card. It still hangs at the same place in the same way, signifying that it's not the PSU at fault. Tried resetting the BIOS again, still nothing. Tried every possible combination of BIOS options, even downclocking everything, it still hangs in the same spot. Tried upgrading the BIOS from version FB to FD, which changed nothing. Based on this, I would conclude the motherboard to be at fault. Are there any other possibilities? I don't want to spend $150 for a new motherboard. EDIT 2: This is what it gets stuck at when I try to boot into safe mode: Note the slight graphical corruption at the top of the screen. No matter how I set up the system, this seems to be there. In addition, either it has stopped booting into safe mode now, or it takes upwards of 2+ hours, and I haven't left it running for that long.

• USB connection is unstable with Nexus S 2.3.4 on AMD 64 running 64-bit Windows 7, but works with 32-bit Windows Vista

  - by Mike

  The USB connection is unstable with Nexus S (Android 2.3.4) on AMD 64 running 64-bit Windows 7, but it works with 32-bit Windows Vista. Problem Description: On the 64-bit Windows 7 machine my Nexus S appears to connect, but then it disconnects moments later. Neither accessing USB storage or loading an Android application package file (APK) using the Android Debug Bridge (ADB) work. On 32-bit Windows Vista using the same USB cable, USB storage works. I haven't tried the ADB on 32-bit Windows Vista. Reproduction steps for USB storage: (I have provided the reproduction steps for USB storage and not ADB, because if one isn't working, then the other isn't working either and the USB storage reproduction steps are shorter to document.) Connect the USB cable to the Nexus S and my Windows 7 machine. Effect: The "USB Mass Storage, USB Connected" dialog appears with the button "Turn on USB storage." Click "Turn on USB Storage" Effect: The "working circle" appears. A dialog briefly appears saying "USB storage in use," then it either returns me to Step 1 (now that I am running 2.3.4) or is replaced with the Nexus S's application homepage (while I was running 2.3.3). I'm not sure if the version matters, but I mention it for completeness. On the 32-bit Windows Vista machine the connection is stable. I am able to navigate through the Nexus S file system create, read, update, and delete files, etc. I haven't tried connecting with the ADB. Troubleshooting summary: Tried and failed: Uninstalling and reinstalling the Android USB drivers including removing the files. Uninstalling my custom software Pulling the Nexus S's battery Restarting the Nexus S Restarting 64-bit Windows 7 Changing USB ports on the 64-bit Windows 7 box Compared the dates and file size on the DLLs in my google-usb_driver\amd64 directory and the windows\System32 directory. They match. The sizes for the google-usb_driver\i386 directory do not match (expected). Turning off Debugging mode on the Nexus S does not resolve the problem. Searching Google. Tried and succeeded: Connecting to another machine (Windows Vista) using the same USB cable and Nexus S phone. Troubleshooting observations: I notice that uninstalling the device drivers and deleting the files, then reinstalling the drivers, then rebooting 64-bit Windows 7 then unplugging the Nexus S, then plugging it back in occasionally helps for a short amount of time (minutes to hours, not days). When it is working, I can both access the Nexus S's drive and load/test applications using the ADB. I have observed some wonky behavior in the Device Manager that I haven't tracked down. Sometimes the black Nexus S image appears in the list of devices. Sometimes the image displays as a computer with a green ISA card. Sometimes it neither appears on the top level of devices nor under “other devices,” but it does appear under "disk drives" as "Android UMS Composite USB Device." System configuration: The Nexus S is running Android OS 2.3.4's "Settings\about phone\System updates" indicates that it is up to date as of May 21st 2011. Both 32-bit Windows Vista and 64-bit Windows 7 are up to date. The Windows Vista system is running on an Intel 32-bit processor. Windows 7 is running on an AMD 64-bit processor. I have done Android development on both systems, but I usually develop on the 64-bit Windows 7 machine.

• Network config / gear question

  - by mcgee1234

  I have been tasked with setting up a fairly straightforward rack in a data center (we do not even need a whole rack, but this is the smallest allotment available). In a nutshell, 4 to 6 servers need to be able to reach 2 (maybe 3) vendors. The servers needs to be reachable over the internet. A little more detail - the networks the servers need to reach are inside of the data center, and are "trusted". Connections to these networks will be achieved through intra data center cross connects. It is kind of like a manufacturing line where we receive data from one vendor (burst-able up to 200 Mbits), churn through it on the servers, and then send out data to another vendor (bursts up to 20 Mbits). This series of events is very latency sensitive, so much so that it is common practice not to use NAT or a firewall on these segments (or so I hear). To reach the servers over the internet, I plan to use a site to site VPN. (This part is only relevant as far as hardware selection goes). I have 2 configurations in mind: Cisco 2911 (2921) (with the additional wan ports module) and a layer 2 switch - in this scenario, I would use the router also for VPN. Cisco 3560 layer 3 switch to interconnect the networks inside of the data center and an ASA 5510 (which is total overkill, but the 5505 is not rack mountable) as a firewall for the Wan side (internet) and VPN. I envision the setup to be as follows: Internet - ASA - 3560 Vendors - 3560 - Servers The general idea is that the ASA acts as a firewall and VPN device and the 3560 does all the heavy lifting. The first is a fairly traditional setup but my concern is performance. The second is somewhat unorthodox in that the vendors are directly connected to the layer 3 switch without passing through a firewall. Based on my understanding however, a layer 3 switch will perform substantially better as it will do hardware (ASIC) vs. software switching. (Note that number 2 is a little over the budget, but not unworkable (double negative, ugh)) Since this is my first time dealing with a data center, I am not sure what the IP space is going to look like. I suspect I will retain a block(s) of public IPs, vlan them to individual interfaces for the vendor connections and the servers (which will not reachable from the wan side of course) and setup routing on the switch. So here are my questionss: Is there a substantial performance difference between 1 and 2, i.e. hardware based switching on a layer 3 vs a software base on the 2911? I have trolled the internet and found a lot of Cisco literature, but nothing that I could really use to get a good handle. The vendors we connect to are secure and trusted (famous last words) and as I understand it, it is common practice not to NAT or firewall these connections (because of the aforementioned latency sensitivity). But what what kind of latency are we really talking about if I push the data through a router (or even ASA for that matter)? For our purposes, 5 ms will not kill us, 20 or 30 can be very costly. Others measure in microseconds, but they are out of our league. Is there any issues with using public IPs on a layer 3 switch? I am certainly not married to either of these configs, and I am totally open to any ideas. My knowledge (and I use the term loosely) is largely from books so I welcome any advice / insight. Thanks in advance.

• I have Oracle SQL Developer Installed, Now What?

  - by thatjeffsmith

  If you’re here because you downloaded a copy of Oracle SQL Developer and now you need help connecting to a database, then you’re in the right place. I’ll show you what you need to get up and going so you can finish your homework, teach yourself Oracle database, or get ready for that job interview. You’ll need about 30 minutes to set everything up…and about 5 years to become proficient with Oracle Oracle Database come with SQL Developer but SQL Developer doesn’t include a database If you install Oracle database, it includes a copy of SQL Developer. If you’re running that copy of SQL Developer, please take a second to upgrade now, as it is WAY out of date. But I’m here to talk to the folks that have downloaded SQL Developer and want to know what to do next. You’ve got it running. You see this ‘Connection’ dialog, and… Where am I connecting to, and who as? You NEED a database Installing SQL Developer does not give you a database. So you’re going to need to install Oracle and create a database, or connect to a database that is already up and running somewhere. Basically you need to know the following: where is this database, what’s it called, and what port is the listener running on? The Default Connection properties in SQL Developer These default settings CAN work, but ONLY if you have installed Oracle Database Express Edition (XE). Localhost is a network alias for 127.0.0.1 which is an IP address that maps to the ‘local’ machine, or the machine you are reading this blog post on. The listener is a service that runs on the server and handles connections for the databases on that machine. You can run a database without a listener and you can run a listener without a database, but you can’t connect to a database on a different server unless both that database and listener are up and running. Each listener ‘listens’ on one or more ports, you need to know the port number for each connection. The default port is 1521, but 1522 is often pretty common. I know all of this sounds very complicated Oracle is a very sophisticated piece of software. It’s not analogous to downloading a mobile phone app and and using it 10 seconds later. It’s not like installing Office/Access either – it requires services, environment setup, kernel tweaks, etc. However. Normally an administrator will setup and install Oracle, create the database, and configure the listener for everyone else to use. They’ll often also setup the connection details for everyone via a ‘TNSNAMES.ORA’ file. This file contains a list of database connection details for folks to browse – kind of like an Oracle database phoneboook. If someone has given you a TNSNAMES.ORA file, or setup your machine to have access to a TNSNAMES file, then you can just switch to the ‘TNS’ connection type, and use the dropdown to select the database you want to connect to. Then you don’t have to worry about the server names, database names, and the port numbers. ORCL – that sounds promising! ORCL is the default SID when creating a new database with the Database Creation Assistant (DBCA). It’s just me, and I need help! No administrator, no database, no nothing. What do you do? You have a few options: Buy a copy of Oracle and download, install, and create a database Download and install XE (FREE!) Download, import, and run our Developer Days Hands-on-Lab (FREE!) If you’re a student (or anyone else) with little to no experience with Oracle, then I recommend the third option. Oracle Technology Network Developer Day: Hands-on Database Application Development Lab The OTN lab runs on a A Virtual Box image which contains: 11gR2 Enterprise Edition copy of Oracle a database and listener running for you to connect to lots of demo data for you to play with SQL Developer installed and ready to connect Some browser based labs you can step through to learn Oracle You download the image, you download and install Virtual Box (also FREE!), then you IMPORT the image you previously downloaded. You then ‘Start’ the image. It will boot a copy of Oracle Enterprise Linux (OEL), start your database, and all that jazz. You can then start up and run SQL Developer inside the image OR you can connect to the database running on the image using the copy of SQL Developer you installed on your host machine. Setup Port Forwarding to Make It Easy to Connect From Your Host When you start the image, it will be assigned an IP address. Depending on what network adapter you select in the image preferences, you may get something that can get out to the internet from your image, something your host machine can see and connect to, or something that kind of just lives out there in a vacuum. You want to avoid the ‘vacuum’ option – unless you’re OK with running SQL Developer inside the Linux image. Open the Virtual Box image properties and go to the Networking options. We’re going to setup port forwarding. This will tell your machine that anything that happens on port 1521 (the default Oracle Listener port), should just go to the image’s port 1521. So I can connect to ‘localhost’ and it will magically get transferred to the image that is running. Oracle Virtual Box Port Forwarding 1521 listener database Now You Just Need a Username and Password The default passwords on this image are all ‘oracle’ – so you can connect as SYS, HR, or whatever – just use ‘oracle’ as the password. The Linux passowrds are all ‘oracle’ too, so you can login as ‘root’ or as ‘oracle’ in the Linux desktop. Connect! Connect as HR to your Oracle database running on the OTN Developer Days Virtual Box image If you’re connecting to someone else’s database, you need to ask the person that manages that environment to create for you an account. Don’t try to ‘guess’ or ‘figure out’ what the username and password is. Introduce yourself, explain your situation, and ask kindly for access. This is your first test – can you connect? I know it’s hard to get started with Oracle. There are however many things we offer to make this easier. You’ll need to do a bit of RTM first though. Once you know what’s required, you will be much more likely to succeed. Of course, if you need help, you know where to find me

• SSH new connection begins to hang (not reject or terminate) after a day or so on Ubuntu 13.04 server

  - by kross

  Recently we upgraded the server from 12.04 LTS server to 13.04. All was well, including after a reboot. With all packages updated we began to see a strange issue, ssh works for a day or so (unclear on timing) then a later request for SSH hangs (cannot ctrl+c, nothing).

This now happens every single time. It is imperative that I get it sorted. The strange thing is that it behaves initially then starts to hang after several hours. I perused logs previously and nothing stood out. From the auth.log, I can see that it has allowed me in, but still I get nothing back on the client side: Sep 20 12:47:50 cbear sshd[25376]: Accepted publickey for tfergeson from 10.1.10.14 port 54631 ssh2 Sep 20 12:47:50 cbear sshd[25376]: pam_unix(sshd:session): session opened for user tfergeson by (uid=0) UPDATES: Still occurring even after setting UseDNS no and commenting out #session optional pam_mail.so standard noenv This does not appear to be a network/dns related issue, as all services running on the machine are as responsive and accessible as ever, with the exception of sshd. Any thoughts on where to start?
