• Fedora 12 on Vmware network disabled on restore

  - by Chaitanya

  I have a fedora 12 guest running on VMWare on windows 7. I use it mainly for the occasional linux dev. Whenever I restart the guest, networking works fine. But if I close the VMware player and save state, the next time I start the image, networking is disabled (red x on the network icon. message saying networking disabled). I can't seem to find a way to restore networking. I have to reboot the guest to get my network access back again. My Ubuntu image doesn't have this problem. I can close the player and when I re run the image, I can pick up where I left off, with all the open firefox windows and application windows as I left them. Fedora saves state, but doesn't seem to enable networking. There is a relevant warning I have seen "SELinux is preventing /sbin/ifconfig "read" access to/var/run/vmware-active-nics." But I am not sure how to solve it. I know fedora isn't officially supported by VMware, but it seems to be working fine for the most part and meeting my needs, except for this one little issue. Any help would be much appreciated.

• Mac OS X Lion (10.7) Drive Encryption

  - by Skoota

  My iMac has two drives (a 256 GB solid-state drive, and regular 2 TB hard drive). The Mac OS X Lion system is installed on the solid-state drive and, like many other users, I have moved my user profile folder onto the secondary 2 TB drive. However, as you may be aware, FileVault 2 on Mac OS X Lion (10.7) only encrypts the system drive. This leaves my data drive (containing my user profile folder, with all of my data) unencrypted. I am aware that work arounds for this issue exist (such as https://github.com/jridgewell/Unlock) but I am not happy with the results since they involve decrypting the data drive on startup using a LaunchDaemon (before any users have logged into the computer) essentially meaning that any user who logs onto the computer will see the unencrypted drive. I would like a method which will only unencrypted the data when an authorised user logs into the computer. As such, is there a way to do one of the following? Encrypt the entire data drive and only decrypt the drive when an authorised user logs into the computer. This would be equivalent behaviour to the Lion FileVault 2 feature, but on a secondary drive rather than the system drive. Encrypt only the user profile folder on the data drive, and only decrypt the folder when the user logs into the computer. This would be equivalent to the behaviour of FileVault 1 on previous versions of Mac OS X? I am happy to pay for a commercial third-party product that provides the required feature(s), but I have not yet been able to find one. Thanks in advance for any assistance.

• Degraded RAID-5 array with lvm2 lost superblock and partition table

  - by Fred Phillips

  I have a RAID-5 array of 4x1TB hard disks with one lvm2 partition on Ubuntu Linux 10.04 LTS. One of the disks has failed. I have re-assembled the array without this failed disk but now mdadm --examine claims the array has no superblock and fdisk says it has no partition table.

• Prevent master to fall back to master after failure

  - by Chrille

  I'm using keepalived to setup a virtual ip that points to a master server. When a failover happens it should point the virtual ip to the backup, and the IP should stay there until I manually enable (fix) the master. The reason this is important is that I'm running mysql replication on the servers and writes should only be on the master. When I failover I promote the slave to master. The master server: global_defs { ! this is who emails will go to on alerts notification_email { [email protected] ! add a few more email addresses here if you would like } notification_email_from [email protected] ! I use the local machine to relay mail smtp_server 127.0.0.1 smtp_connect_timeout 30 ! each load balancer should have a different ID ! this will be used in SMTP alerts, so you should make ! each router easily identifiable lvs_id APP1 } vrrp_instance APP1 { interface eth0 state EQUAL virtual_router_id 61 priority 999 nopreempt virtual_ipaddress { 217.x.x.129 } smtp_alert } Backup server: global_defs { ! this is who emails will go to on alerts notification_email { [email protected] ! add a few more email addresses here if you would like } notification_email_from [email protected] ! I use the local machine to relay mail smtp_server 127.0.0.1 smtp_connect_timeout 30 ! each load balancer should have a different ID ! this will be used in SMTP alerts, so you should make ! each router easily identifiable lvs_id APP2 } vrrp_instance APP2 { interface eth0 state EQUAL virtual_router_id 61 priority 100 virtual_ipaddress { 217.xx.xx.129 } notify_master "/etc/keepalived/notify.sh del app2" notify_backup "/etc/keepalived/notify.sh add app2" notify_fault "/etc/keepalived/notify.sh add app2” smtp_alert }

• ZFS with L2ARC (SSD) slower for random seeks than without L2ARC

  - by Florian Kruse

  I am currently testing ZFS (Opensolaris 2009.06) in an older fileserver to evaluate its use for our needs. Our current setup is as follows: Dual core (2,4 GHz) with 4 GB RAM 3x SATA controller with 11 HDDs (250 GB) and one SSD (OCZ Vertex 2 100 GB) We want to evaluate the use of a L2ARC, so the current ZPOOL is: $ zpool status pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM afstank ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c11t0d0 ONLINE 0 0 0 c11t1d0 ONLINE 0 0 0 c11t2d0 ONLINE 0 0 0 c11t3d0 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c13t0d0 ONLINE 0 0 0 c13t1d0 ONLINE 0 0 0 c13t2d0 ONLINE 0 0 0 c13t3d0 ONLINE 0 0 0 cache c14t3d0 ONLINE 0 0 0 where c14t3d0 is the SSD (of course). We run IO tests with bonnie++ 1.03d, size is set to 200 GB (-s 200g) so that the test sample will never be completely in ARC/L2ARC. The results without SSD are (average values over several runs which show no differences) write_chr write_blk rewrite read_chr read_blk random seeks 101.998 kB/s 214.258 kB/s 96.673 kB/s 77.702 kB/s 254.695 kB/s 900 /s With SSD it becomes interesting. My assumption was that the results should be in worst case at least the same. While write/read/rewrite rates are not different, the random seek rate differs significantly between individual bonnie++ runs (between 188 /s and 1333 /s so far), average is 548 +- 200 /s, so below the value w/o SSD. So, my questions are mainly: Why do the random seek rates differ so much? If the seeks are really random, they should not differ much (my assumption). So, even if the SSD is impairing the performance it should be the same in each bonnie++ run. Why is the random seek performance worse in most of the bonnie++ runs? I would assume that some part of the bonnie++ data is in the L2ARC and random seeks on this data performs better while random seeks on other data just performs similarly like before.

• PowerPoint avoid animation completion on click & advance slide or start new one

  - by ScottS

  Scenario I have PowerPoint 2010 On the "Transitions" tab the "Advance Slide On Mouse Click" check box is checked. I have a long, slow, timed, non-repeating animation working in the background of the slide. I click to advance the slide before the animation is finished, but ... Instead of advancing the slide, the animation moves to the completed state ... Forcing a second click to actually advance the slide. Additionally If I have other animations on the slide that are initiated by a click, the long animation also advances to a finished state before starting the new animation. Desired Behavior On click, I want the slide to advance or the next on-click animation to start whether the long animation is done or not, and without having that long animation first "complete" itself. In the case of another animation, I simply want the long animation to continue, while also doing the new animation. Ultimate Question Is there a way to either: Set an option somewhere to not have that animation complete on click and simply "continue" to animate with the start of a new animation or to advance the slide (as the case may be)? Create a VBA script that will produce the desired behavior for the long animation?

• Secretary cannot add appointments to boss's calendar after exchange restore from backup

  - by therulebookman

  The calendar is the Boss's calendar on Exchange. I have set permissions for it through his Outlook to give the secretary and a few other people "Editor" access to his calendar. All the editors can view the calendar, but only he can add new appointments. Anyone else who tries to add an appointment gets "The item cannot be saved in this folder. The folder was deleted or moved or you do not have permission." The permissions are correct, editor. The item hasn't been deleted or moved. It's in his mailbox on exchange. The message says something about the mailbox size, but he is well under the size limit anyway. He is using Outlook 2003, and I have tried accessing it from 2003 and 2007, but I don't think that is related I tried clearing the forms cache and enabling disabled items: no disabled items and clearing cache didn't help. I also tried "Allow all forms" but this apparently doesn't apply in this scenario as we are not using any custom forms. Is there any way to delete just his calendar and then I can exmerge it back in (after exporting to PST of course)? I really can't exmerge out his mailbox, delete it, and exmerge it back in because he works all sorts of hours, but if this is the only way, then I'll have to do it. Is there any other possible solution?

• mysql INNODB inserts very slow

  - by 133794m3r

  The database's schema is as follows. CREATE TABLE `items` ( `id` mediumint( 8 ) unsigned NOT NULL AUTO_INCREMENT , `name` varchar( 45 ) NOT NULL , `main_type` tinyint( 4 ) NOT NULL , `rarity` tinyint( 4 ) NOT NULL , `stack_size` smallint( 6 ) NOT NULL , `sub_type` tinyint( 4 ) NOT NULL , `cost` mediumint( 8 ) unsigned NOT NULL , `ilvl` smallint( 6 ) unsigned NOT NULL DEFAULT '0', `flavor_text` varchar( 250 ) NOT NULL , `rlvl` tinyint( 3 ) unsigned NOT NULL , `final` tinyint( 4 ) NOT NULL DEFAULT '0', PRIMARY KEY ( `id` ) ) ENGINE = InnoDB DEFAULT CHARSET = ascii; Now, doing an insert on this table takes 0.22 seconds. I don't know why it's taking so long to do a single row insert. Reads are really really fast something like 0.005 seconds. With using the example configuration from here dev mysql innodb it averages ~0.002 to ~0.005 seconds. Why it takes more than 100x more time to do a single insert makes no sense to me. My computer is as follows. OS:Debian Sid x86-x64, Mysql 5.1, RAM:4GB ddr2, cpu 2.0Ghz dual core, HDD 7200RPM 32MB cache 640GB. Why it's taking almost 100x as much time for a SELECT * FROM items; vs INSERT INTO items ...; will never make any sense to me. It's still a small table at only 70 rows, and took that long even when it had 0 rows.

• Juniper’s Network Connect ncsvc on Linux: “host checker failed, error 10”

  - by hfs

  I’m trying to log in to a Juniper VPN with Network Connect from a headless Linux client. I followed the instructions and used the script from http://mad-scientist.us/juniper.html. When running the script with --nogui switch the command that gets finally executed is $HOME/.juniper_networks/network_connect/ncsvc -h HOST -u USER -r REALM -f $HOME/.vpn.default.crt. I get asked for the password, a line “Connecting to…” is printed but then the programm silently stops. When adding -L 5 (most verbose logging) to the command line, these are the last messages printed to the log: dsclient.info state: kStateCacheCleaner (dsclient.cpp:280) dsclient.info --> POST /dana-na/cc/ccupdate.cgi (authenticate.cpp:162) http_connection.para Entering state_start_connection (http_connection.cpp:282) http_connection.para Entering state_continue_connection (http_connection.cpp:299) http_connection.para Entering state_ssl_connect (http_connection.cpp:468) dsssl.para SSL connect ssl=0x833e568/sd=4 connection using cipher RC4-MD5 (DSSSLSock.cpp:656) http_connection.para Returning DSHTTP_COMPLETE from state_ssl_connect (http_connection.cpp:476) DSHttp.debug state_reading_response_body - copying 0 buffered bytes (http_requester.cpp:800) DSHttp.debug state_reading_response_body - recv'd 0 bytes data (http_requester.cpp:833) dsclient.info <-- 200 (authenticate.cpp:194) dsclient.error state host checker failed, error 10 (dsclient.cpp:282) ncapp.error Failed to authenticate with IVE. Error 10 (ncsvc.cpp:197) dsncuiapi.para DsNcUiApi::~DsNcUiApi (dsncuiapi.cpp:72) What does host checker failed mean? How can I find out what it tried to check and what failed? The HostChecker Configuration Guide mentions that a $HOME/.juniper_networks/tncc.jar gets installed on Linux, but my installation contains no such file. From that I concluded that HostChecker is disabled for my VPN on Linux? Are the POST to /dana-na/cc/ccupdate.cgi and “host checker failed” connected or independent? By running the connection over a SSL proxy I found out that the POST data is status=NOTOK (Funny side note: the client of the oh-so-secure VPN does not validate the server’s SSL certificate, so is wide open to MITM attacks…). So it seems that it’s the client that closes the connection and not the server.

• keepalived issues on xen domU

  - by David Cournapeau

  Hi, I cannot manage to run keepalived correctly on xen domU. I am following this link for configuration, and it works great on some local VM (running with KVM). If I set up the exact same configuration, but on xen domU, it does not work: both servers do not see each other and decide to be master (10.120.100.99 being the virtual IP) $ sudo ip addr sh eth0 # host1 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:16:3e:78:f5:31 brd ff:ff:ff:ff:ff:ff inet 10.120.100.104/24 brd 10.120.100.255 scope global eth0 inet 10.120.100.99/32 scope global eth0 inet6 fe80::216:3eff:fe78:f531/64 scope link valid_lft forever preferred_lft forever $ sudo ip addr sh eth0 # host2 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:16:3e:51:36:20 brd ff:ff:ff:ff:ff:ff inet 10.120.100.105/24 brd 10.120.100.255 scope global eth0 inet 10.120.100.99/32 scope global eth0 inet6 fe80::216:3eff:fe51:3620/64 scope link valid_lft forever preferred_lft forever Is there a way I could debug this - it seems some people are able to use keepalived on xen following some mailing list, but without much info on their config.

• IP-dependent local port-forwarding on Linux

  - by chronos

  I have configured my server's sshd to listen on a non-standard port 42. However, at work I am behind a firewall/proxy, which only allow outgoing connections to ports 21, 22, 80 and 443. Consequently, I cannot ssh to my server from work, which is bad. I do not want to return sshd to port 22. The idea is this: on my server, locally forward port 22 to port 42 if source IP is matching the external IP of my work's network. For clarity, let us assume that my server's IP is 169.1.1.1 (on eth1), and my work external IP is 169.250.250.250. For all IPs different from 169.250.250.250, my server should respond with an expected 'connection refused', as it does for a non-listening port. I'm very new to iptables. I have briefly looked through the long iptables manual and these related / relevant questions: http://serverfault.com/questions/57872/iptables-question-forwarding-port-x-to-an-ssh-port-of-different-machine-on-the-n http://serverfault.com/questions/140622/how-can-i-port-forward-with-iptables However, those questions deal with more complicated several-host scenarios, and it is not clear to me which tables and chains I should use for local port-forwarding, and if I should have 2 rules (for "question" and "answer" packets), or only 1 rule for "question" packets. So far I have only enabled forwarding via sysctl. I will start testing solutions tomorrow, and will appreciate pointers or maybe case-specific examples for implementing my simple scenario. Is the draft solution below correct? iptables -A INPUT [-m state] [-i eth1] --source 169.250.250.250 -p tcp --destination 169.1.1.1:42 --dport 22 --state NEW,ESTABLISHED,RELATED -j ACCEPT Should I use the mangle table instead of filter? And/or FORWARD chain instead of INPUT?

• SendMail not working in CentOs 6.4

  - by Kane

  I am trying to send e-mails from my CentOS 6.4 but it does not work. My knowledge about servers is quite limited, so I hope someone can help me. Here is what I did: First i tried to send an email using the "mail" command, but it was not in the OS so I installed it. # yum install mailx After that, I tried sending an email using the "mail" command, but it did not send anything. I checked it on the internet and I realized I needed an e-mail server like sendmail, so I installed it. # yum install sendmail sendmail-cf sendmail-doc sendmail-devel After that, I configured it following some tutorials. First, sendmail.mc file. # vi /etc/mail/sendmail.mc Commented out the next line: BEFORE # DAEMON_OPTIONS('Port=smtp, Name=MTA') dnl AFTER # dnl DAEMON_OPTIONS('Port=smtp, Name=MTA') dnl Check that the next lines are correct: # FEATURE(`virtusertable', `hash -o /etc/mail/virtusertable.db')dnl # ... # FEATURE(use_cw_file)dnl # ... # FEATURE(`access_db', `hash -T<TMPF> -o /etc/mail/access.db')dnl Update sendmail.cf # m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf Open the port 25 adding the proper line in the iptables file # vi /etc/sysconfig/iptables # -A INPUT -m state --state NEW -m tcp --dport 25 -j ACCEPT restart iptables and sendmail # service iptables restart # service sendmail restart So i thought that would be ok, but when i tried: # mail '[email protected]' # Subject: test subject # test content #. I checked the mail log: # vi /var/log/maillog And that is what I found: Aug 14 17:36:24 dev-admin-test sendmail[20682]: r7D8RItS019578: to=<[email protected]>, ctladdr=<[email protected]> (0/0), delay=1+00:09:06, xdelay=00:00:00, mailer=esmtp, pri=2460500, relay=alt4.gmail- smtp-in.l.google.com., dsn=4.0.0, stat=Deferred: Connection timed out with alt4.gmail-smtp-in.l.google.com. I do not understand why there is a connection time out. Am I missing something? Can anyone help me, please? Thank you.

• Raid-z unaccessible after putting one disk offline

  - by varesa

  I have installed FreeNAS on a test server, with 3x 1Tb drives. They are setup in raidz. I tried to offline one of the disks (from the FreeNAS web-ui), and the array became degraded, as I think it should. The problem is with the array becoming unaccessible after that. I thought a raid like that should be able to run fine with one of the disks missing. Atleast very soon after I offline'd and pulled out the disk, the iSCSI share disappeared from a ESXi host's datastores. I also ssh'd into the FreeNAS server, and tried just executing ls /mnt/raid (/mnt/raid/ being the mount point). The whole terminal froze, not accepting ^C or anything. # zpool status -v pool: raid state: DEGRADED status: One or more devices are faulted in response to IO failures. action: Make sure the affected devices are connected, then run 'zpool clear'. see: http://www.sun.com/msg/ZFS-8000-HC scrub: none requested config: NAME STATE READ WRITE CKSUM raid DEGRADED 1 30 0 raidz1 DEGRADED 4 56 0 gptid/c8c9e44c-08e1-11e2-9ba6-001b212a83ea ONLINE 3 60 0 gptid/c96f32d5-08e1-11e2-9ba6-001b212a83ea ONLINE 3 63 0 gptid/ca208205-08e1-11e2-9ba6-001b212a83ea OFFLINE 0 0 0 errors: Permanent errors have been detected in the following files: /mnt/raid/ raid/iscsivol:<0x0> raid/iscsivol:<0x1> Have I understood the workings of a raidz wrong, or is there something else going on?

• Barriers to IPv6 deployment: addressing

  - by sysadmin1138

  There are several things that are keeping IPv6 deployment from being a topic of active discussion here at my work. There are the usual technical issues, but one non-technical one appears to be a major stumbling block on the path to actually getting a deployment project going. Addresses, memorizing of. Specifically, IPv4 addresses are comprehensible, and IPv6 addresses just look like a big long string of hex. The human mind has real trouble memorizing lists of more than 7-8 items, and an IPv4 address (192.168.231.148) has four items in it which makes it easy for us to memorize. A fully populated IPv6 address has not only 8 sections, but each section has 4 hex digits in it. IPv6 addresses were not designed for memorization. To the technician who knows that the DNS server is at 192.168.42.42 (or more likely "42.42", since the company prefix is likely memorized), the idea of memorizing an IPv6 address fills them with dread. Which in turn makes them much less enthusiastic about participating in an IPv6 deployment project. Because of how our network works we're not fully dynamic in terms of v4 addressing. We have several to many subnets that are entirely statically assigned for a variety of reasons, chief among them being that the overhead of static DHCP assignments is perceived as being too great. Also, some devices still aren't smart enough to pull DNS addresses out of DHCP while also having a static assignment, and therefore require manually configured DNS settings. Therefore, some v6 address memorization will have to be done. We're not under any mandate to get v6 out the door, so we don't have pressure from the top. However, it is time to start prepping our infrastructure to handle IPv6 even if we don't convert wholesale. For those of you who have been in IPv6-land for a while, what short-cut methods do you use to discuss or keep track of subnets and specific/critical IP addresses? If I can help reduce some of the dread surrounding IPv6 we might get the project going.

• SQL Server Database In Single User Mode after Failover

  - by jlichauc

  Here is a weird situation we experienced with a SQL Server 2008 Database Mirroring Failover. We have a pair of mirrored databases running in high-availability mode and both the principal and mirror showed as synchronized. As part of some maintenance I triggered a manual failover of the principal to the mirror. However after the failover the principal was now in single-user mode instead of the expected "Principal/Synchronized" state we usually get. The database had been in multi-user mode on the previous principal before this had happened. We ended up stopping all applications, restarting the SQL Server instances, and executing "ALTER DATABASE ... SET MULTI_USER" to bring the database back to the expected "Principal/Synchronized" state in a multi-user mode. Question. Does anyone know where SQL Server stores information about whether a database should be in single-user mode or not? I'm wondering if there is some system database or table that has this setting recorded somewhere. In particular we had an incident once with the database on the original principal (the one I was failing over to) where when trying to detach the database it was put into single-user mode. I'm wondering if that setting is cached somewhere and is the reason that SQL Server put it back into single-user mode after a failover.

• How do I reinitialise a failed RAID 5 drive using terminal on Ubuntu Server

  - by Stephen

  I've currently put together a new system and part of that has been creating a software RAID 5 using 'mdadm' in Ubuntu Server. I successfully got to the point where I create the array using: sudo mdadm --create --verbose /dev/md0 --level=5 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 I left it to do its thing overnight then used the following command to check on it: watch cat /proc/mdstat To which the following was returned: Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid5 sdd1[4](S) sdc1[2] sdb1[1] sda1[0](F) 5860535808 blocks super 1.2 level 5, 512k chunk, algorithm 2 [4/2] [_UU_] unused devices: <none> It appears that one has failed (and I'm not too savvy with why another is a spare). So, just to be sure that something else isn't amiss I wanted to try and re-engage the failed drive. Can someone explain how I can do that and what I should do with the spare (if anything). And also how do I know when synchronisation is complete? The tutorial I used to get this far is located here: http://sonniesedge.co.uk/2009/06/13/software-raid-5-on-ubuntu-904/ Many thanks! p.s.

• Best tool for monitoring backups, etc. and trending statstics from that data

  - by Randy Syring

  I have done some research on nagios, opennms, and zenoss but am not confident that I have found what I am looking for. The main driving force for me right now is being able to monitor backups. This includes mysql, mssql, and eventually some file system backups. We have a tool that wraps the backup process for these different systems and collects statistics. So, items like: number of databases backed up size of db backup file size of db backup file compressed time to make backup time to zip file I want to be able to A) have notifications if the jobs are not run according to schedule B) be able to set thresholds on the statistics which would trigger notifications C) I want to be able to trend and graph the statistics I am planning on sending this information to the monitoring application through an HTTP POST. Or, the monitoring application could pull it from a log file as well. However, we will have other processes with other "arbitrary" (from the monitoring system's perspective) statics that will want to monitor and trend, so flexibility is very important. The tool or tools should also be able to do general monitoring and trending of network interfaces, server load, etc. Once we get the backup monitoring in place, we will want to include those items as well. Thanks.

• Destination NAT Onto the Same Network from internal clients

  - by mivi

  I have a DSL router which acts as NAT (SNAT & DNAT). I have setup a server on internal network (10.0.0.2 at port 43201). DSL router was configured to "port forward" (or DNAT) all incoming connections to 10.0.0.2:43201. I created a virtual server for port forwarding on DSL router. I also added following iptables rules for port forwarding. iptables -t nat -A PREROUTING -p tcp -i ppp_0_1_32_1 --dport 43201 -j DNAT --to-destination 10.0.0.2:43201 iptables -I FORWARD 1 -p tcp -m state --state NEW,ESTABLISHED,RELATED -d 10.0.0.2 --dport 43201 -j ACCEPT # ppp_0_1_32_1 is routers external interface. # routers internal IP address is 10.0.0.1 and server is setup at 10.0.0.2:43201 Problem is that connections coming from external IP addresses are able to access internal server using External IP address, but internal clients (under NAT) are not able to access server using external IP address. Example: http://<external_address>:43201 is working from external clients But, internal clients are not able to access using http://<external_address>:43201 This seems to be similar to the problem described in http://www.netfilter.org/documentation/HOWTO/NAT-HOWTO-10.html (NAT HOW-TO Destination NAT Onto the Same Network). Firstly, I am not able to understand why is this a problem for internal clients? Secondly, what iptables rule will enable internal clients to access server using external IP address? Please suggest.

• How to re-add a RAID-10 failed drive on Ubuntu?

  - by thiesdiggity

  I have a problem that I can't seem to solve. We have a Ubuntu server setup with RAID-10 and two of the drives dropped out of the array.

The RAID-10 is part of the /dev/mapper, could that be the reason why the device is coming back as busy? Anyone have any suggestions on what I can try to get the drives back into the array? Any help would be greatly appreciated. Thanks!

• Routing table on Linux not respected

  - by MRHaarmann

  I have a very specific problem, building a Linux VPN endpoint (with external VPN Gateway), which should route certain networks over the tunnel, others via default gateway. The Linux VPN should do a NAT on the outgoing connections for the VPN peers. Setup is as following: Internet gateway LAN 192.168.25.1/24 VPN Gateway LAN 10.45.99.2/24 (VPN tunnel 10.45.99.1 to net 87.115.17.40/29, separate connection to Internet) Linux VPN Router eth0 192.168.25.71/24 eth0:503 10.45.99.1/24 Default 192.168.25.1 route to 87.115.17.40/29 via 10.45.99.2 (send_redirects disabled, ip_forward enabled) Linux clients (multiple): eth0 192.168.25.x/24 Default 192.168.25.1 route to 87.115.17.40/29 via 192.168.25.71 Ping to the machines via tunnel from the VPN Router is working. Now I want to establish a routing from my clients over the VPN gateway and the client packet gets routed to 192.168.25.1 ! traceroute output shows the packets get routed to 192.168.25.71, but then to 192.168.25.1. So the route is not respected in forward ! IPTables and Routing: ip route show 87.115.17.40/29 via 10.45.99.2 dev eth0 10.45.99.0/24 dev eth0 proto kernel scope link src 10.45.99.1 192.168.25.0/24 dev eth0 proto kernel scope link src 192.168.25.71 default via 192.168.25.1 dev eth0 iptables -A INPUT -i eth0:503 -j REJECT iptables -t nat -A POSTROUTING -o eth0:503 -j MASQUERADE iptables -A FORWARD -i eth0:503 -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 192.168.25.0/24 -o eth0:503 -j ACCEPT So what is wrong with my setup ? The route is chosen correctly from localhost, but all the clients get forwarded to the Internet GW. thanks for helping, Marcus

• Host name change breaking http? Fedora

  - by Dave

  OK so I have been messing around on my development server. It has been a while since I have had my head in linux and I suspect I have broken something. I have SSH running and that is working fine. I also have HTTP and I had FTP running also. Earlier today I decided I wanted to rename the machine so I updated the /etc/hosts file and /etc/sysconfig/network. I also changed the server name in the httpd.conf. I rebooted the machine and reconnected to SSH fine. Later I was messing around with the FTP service (trying to tighten up the user security) and when i tried to connect remotely to FTP no joy, it said cannot connect. I thought that was weird but had planned to remove ftp as we will be using github so removed ftp and moved on. Then I tried to connect to the website but major fail. even connecting to the IP address is failing. I used lynx to connect to the localhost and there was my site so something going on at server level. I thought maybe something up with iptables but I have not changed them but tried adding http but still no joy. I have a - Fedora release 17 (Beefy Miracle) NAME=Fedora VERSION="17 (Beefy Miracle)" ID=fedora VERSION_ID=17 PRETTY_NAME="Fedora 17 (Beefy Miracle)" ANSI_COLOR="0;34" CPE_NAME="cpe:/o:fedoraproject:fedora:17" Fedora release 17 (Beefy Miracle) Fedora release 17 (Beefy Miracle) Linux version 3.3.4-5.fc17.x86_64 ([email protected]) (gcc version 4.7.0 20120504 (Red Hat 4.7.0-4) (GCC) ) #1 SMP Mon May 7 17:29:34 UTC 2012 This is my iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT icmp -- anywhere anywhere ACCEPT all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh REJECT all -- anywhere anywhere reject-with icmp-host-prohibited Chain FORWARD (policy ACCEPT) target prot opt source destination REJECT all -- anywhere anywhere reject-with icmp-host-prohibited Chain OUTPUT (policy ACCEPT) target prot opt source destination Like I say I can use SSH no issue but http although running is a no go from a remote computer. Any ideas?
