• Routing subnet over GRE tunnel

  - by eMgz

  Hi, Im trying to configure a GRE over IPSec connection between two subnets. The IPSec tunnel is opened and now I want to add a GRE tunnel over it: ip tunnel add GRE01 mode gre remote 10.244.0.1 local 10.244.245.32 ttl 255 ip link set GRE01 up ip addr add 10.244.248.126 dev GRE01 ip route add 10.244.248.125 dev GRE01 Now I have an interface GRE01 (ifconfig): GRE10 Link encap:UNSPEC HWaddr <h_addr> inet addr:10.244.248.126 P-t-P:10.244.248.126 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MTU:1476 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) And the following routes (ip route list): 10.244.248.125 dev GRE10 scope link <pub_subnet> dev eth0 proto kernel scope link src <pub_ip> default via <pub_gw> dev eth0 metric 100 As a last step, I need now to route my subnet over the tunnel: ip route add 10.245.1.224/28 10.244.248.125 However, I am getting the error Error: either "to" is duplicate, or "10.244.248.125" is a garbage. So, what I didn't understand is why I can't route my subnet over the tunnel, once the only route I have there says that it should route the tunnel IP over the GRE01 interface. Any hint? Thanks.

• 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.

• Courier-imap login problem after upgrading / enabling verbose logging

  - by halka

  I've updated my mail server last night, from Debian etch to lenny. So far I've encountered a problem with my postfix installation, mainly that I managed to broke the IMAP access somehow. When trying to connect to the IMAP server with Thunderbird, all I get in mail.log is: Feb 12 11:57:16 mail imapd-ssl: Connection, ip=[::ffff:10.100.200.65] Feb 12 11:57:16 mail imapd-ssl: LOGIN: ip=[::ffff:10.100.200.65], command=AUTHENTICATE Feb 12 11:57:16 mail authdaemond: received auth request, service=imap, authtype=login Feb 12 11:57:16 mail authdaemond: authmysql: trying this module Feb 12 11:57:16 mail authdaemond: SQL query: SELECT username, password, "", '105', '105', '/var/virtual', maildir, "", name, "" FROM mailbox WHERE username = '[email protected]' AND (active=1) Feb 12 11:57:16 mail authdaemond: password matches successfully Feb 12 11:57:16 mail authdaemond: authmysql: sysusername=<null>, sysuserid=105, sysgroupid=105, homedir=/var/virtual, [email protected], fullname=<null>, maildir=xoxo.sk/[email protected]/, quota=<null>, options=<null> Feb 12 11:57:16 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=105, sysgroupid=105, homedir=/var/virtual, [email protected], fullname=<null>, maildir=xoxo.sk/[email protected]/, quota=<null>, options=<null> ...and then Thunderbird proceeds to complain that it cant' login / lost connection. Thunderbird is definitely not configured to connect through SSL/TLS. POP3 (also provided by Courier) is working fine. I've been mainly looking for a way to make the courier-imap logging more verbose, like can be seen for example here. Edit: Sorry about the mess, I've found that I've been funneling the log through grep imap, which naturally didn't display entries for authdaemond. The verbose logging configuration entry is found in /etc/courier/imapd under DEBUG_LOGIN=1 (set to 1 to enable verbose logging, set to 2 to enable dumping plaintext passwords to logfile. Careful.)

• Getting SMB file shares working over a PPTP VPN

  - by Ben Scott

  I'm having issues getting SMB file shares working over a PPTP VPN. The server setup consists of a security device (DrayTek V3300) which passes the PPTP authentication to a SBS2003 server running RRAS. The server is the DC and provides DNS and WINS, the single NIC's name server is set to 127.0.0.1, and DHCP on the DrayTek sets the server IP as the DNS. If I create a new VPN connection in Win7, leaving everything as default apart from the server, username, password and domain, I can: ping everything by IP address resolve IPs with nslookup using their fully-qualified name, as in nslookup fileserver.mydomain.local ping machines by fully-qualified name, as in ping fileserver.mydomain.local However if I try to access a file share: within Explorer, I get "Windows cannot access ..." with "Error code: 0x80004005 Unspecified Error", using net use z: \\fileserver.mydomain.local\share, I get "System error 53 has occurred. The network path was not found." If I add the machine name to my HOSTS file I can use the file share, which is my last-ditch workaround, but I have a number of VPN users and would rather a solution that doesn't involve me trying to hand-edit system files on computers half a country away. If I set the WINS server explicitly in the connection's IPv4 settings I don't have to use the FQN to ping the machine, but that doesn't change anything else.

• TFTP Timing Out on Ubuntu VM

  - by valsidalv

  I'm running a Windows 7 PC with VMware installed which has my Ubuntu (10.04 Lucid Lynx). I recently installed a DHCP server and TFTP (Xinet tftpd) using these instructions. I've mapped a network drive so that my Windows has access to all the files in my VM through a 192.x.x.x IP address. I'm trying to throw some custom firmware onto a router. The router has its own built-in TFTP utility that will download the image. It successfully manages to do everything but it is slow because it writes it to flash memory. There is another method that is much quicker because it writes to RAM directly but it must use the TFTP server in Ubuntu. The issue I'm facing is that the Ubuntu TFTP transfer seems to be timing out. The transfer starts but never goes past ~60%. Here's my /etc/xinetd.d/tftp file (similar to a known working config): service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = -s /home/user/tftp/ disable = no cps = 300 2 per_source = 60 } I've done some searching but can't find any parameters for this file to control timeout time or number of retries. The last two arguments (cps, per_source) and completely alien to me (can anyone explain). I have a few possible solutions but the easiest would be to get this TFTP server working. Can anyone help? Either with a timeout configuration or maybe even recommend a different TFTP server? Thanks!

• SQUID proxy - open FTP (and other ports)

• What to look for in a reliable backup hard disk?

  - by Senthil

  I want to buy an internal hard disk and use a docking station along with it for backing up important data. The size will be around 500GB to 1TB. I have a budget and several models fit into it. So far, they only seem to vary in size, speed and brand. These are the only things I can compare from the specs. I guess asking for which brand is best is completely subjective so I won't do that. I want my disk to have long life and be reliable. Doesn't matter if it is somewhat slow. Size: Should I go for the one with highest size within my budget? Will higher density cause problems? Or should I go for a moderately sized one? Does the number of platters have an impact? Speed: I do not want high performance. I want it to be reliable and last long. I am definitely not going to choose the expensive 10,000 rpm ones. Should I go for 5400 or 7200? Do these numbers affect longevity and reliability? Are there any other technical and objective factors that I should look for?

• What can I do to prevent system power downs?

  - by Joe King

  Yesterday I was given my brother's old laptop - core i7, 2.67GHz, 8GB RAM, 128GB SSD, Win7 64 bit. It's a Sony Vaio Z11. Approx 18 months old. When running something computationally intensive, the fan starts up and after about 30 secs it just powers itself down with no warning. I guess it is overheating. There is nothing in the event logs to suggest what is causing it - the only thing I see is "the last system shutdown was unexpected" or something similar. This is a problem for me because I use a lot of number crunching apps, which pretty much makes it useless to me. I would like to know if there is anything I can do, other than the obvious things I've done already - open up and clean out dust, re-install the OS. According to my brother, this problem started about 6 months ago when it was already outside warranty. If it's just used for simple things - web browsing, word processing etc, the problem does not occur. Any ideas for what I can do to fix this ? Update: I found that the laptop has 2 hardware settings for graphics: Speed and Stamina - the Speed setting seems to use an nvidia GEforce GT 330M, while the Stamina setting uses an Intel chipset. With the setting on Speed, I can hear the fan the whole time, and the system powers down after a short while (5-10 mins) even just doing basic tasks (browsing this site for example), but doesn't shut down if I just leave it switched on. In this mode it also sometimes just freezes the screen and I have to power off myself. However on Stamina setting it only powers down when doing number crunching and never freezes the screen.

• pptpd not working externally on Ubuntu Server 11.10

  - by Brendan

  I am trying to set up a pptpd vpn on our newly installed Ubuntu 11.10 64 bit server, but am not having success having a client connect via an iPhone to the VPN.

• What is the best way to recover from a mysql replication fail?

  - by Itai Ganot

  Today, the replication between our master mysql db server and the two replication servers dropped. I have a procedure here which was written a long time ago and i'm not sure it's the fastest method to recover for this issue. I'd like to share with you the procedure and I'd appreciate if you could give your thoughts about it and maybe even tell me how it can be done quicker. At the master: RESET MASTER; FLUSH TABLES WITH READ LOCK; SHOW MASTER STATUS; And copy the values of the result of the last command somewhere. Wihtout closing the connection to the client (because it would release the read lock) issue the command to get a dump of the master: mysqldump mysq Now you can release the lock, even if the dump hasn't end. To do it perform the following command in the mysql client: UNLOCK TABLES; Now copy the dump file to the slave using scp or your preferred tool. At the slave: Open a connection to mysql and type: STOP SLAVE; Load master's data dump with this console command: mysql -uroot -p < mysqldump.sql Sync slave and master logs: RESET SLAVE; CHANGE MASTER TO MASTER_LOG_FILE='mysql-bin.000001', MASTER_LOG_POS=98; Where the values of the above fields are the ones you copied before. Finally type START SLAVE; And to check that everything is working again, if you type SHOW SLAVE STATUS; you should see: Slave_IO_Running: Yes Slave_SQL_Running: Yes That's it! At the moment i'm in the stage of copying the db from the master to the other two replication servers and it takes more than 6 hours to that point, isn't it too slow? The servers are connected through a 1gb switch.

• Server nearly unusable when doing disk writes

  - by Wikser

  My question closely relates to my last question here on serverfault. I was copying about 5GB from a 10 year old desktop computer to the server. The copy was done in Windows Explorer. In this situation I would assume the server to be bored by the dataflow. But as usual with this server, it really slowed down. At least I could work with the remote session, even there was some serious latency. The copy took its time (20min?). In this time I went to a colleague and he tried to log in in the same server via remote desktop (for some other reason). It took about a minute to get to the login screen, a minute to open the control panel, a minute to open the performance monitor, ... Icons were loading maybe one per second. We saw the following (from memory): CPU: 2% Avg. Queue Length: 50 Pages/sec: 115 (?) There was no other considerable activity on the server. The server seldom serves some ASP.NET pages, which became also very slow in this time. The relevant configuration is as follows: Windows 2003 SEAGATE ST3500631NS (7200 rpm, 500 GB) LSI MegaRAID based RAID 5 4 disks, 1 hot spare Write Through No read-ahead Direct Cache Mode Harddisk-Cache-Mode: off Is this normal behaviour for such a configuration? What measurements could give further clues? Is it reasonable to reduce the priority of such copy I/O and favour other processes like the remote desktop? How would you do that? Many thanks!

• Installing Windows 7 over PXE, preferably with domain autojoin

  - by Ivan Vucica

  At an educational non-profit, I've inherited a previously set-up Windows domain that, after the first reinstall of the machines, we ended up not using by simply not joining machines back into the domain. Over last summer, before the annual reinstall for shipping machines to the summer school, I toyed with the idea of installing Windows 7 over network, instead of just imaging the machines. It took a bit longer than I expected to figure out the basics; honestly, I expected that Windows would be more friendly for PXE installation out of the box. What I'm interested in is best practices for installing Windows 7 over PXE with domain autojoin. I'd love it if the whole setup could optionally be hosted on a UNIX based system as well. I've had some success by preparing an ISO using Windows Deployment Kit, and loading the ISO into memory. This was needed since I wanted a menu, and I think I couldn't get PXELINUX to chainload into Windows' bootloader. Unfortunately, I couldn't figure out much about customization of the Windows setup in that timeframe nor could I get Samba to work properly; studying the stuff ended up being too lengthy, especially the portion where I edited a disk image on Windows and copied it outside. WDK didn't make things easier by mounting the disk image into RAM, and writing it in its entirety when done with it, making me a very sad boy. I've recently found a different approach, too, that appears to be closer to Microsoft's original idea for netboot deployment and does not involve ISOs. So my question boils down to the following. What exact approach do you use for netbooting Windows 7 setup? How can Windows 7 setup be best customized to be completely unattended, including installation on specific system partition and not destroying the data partition, creation of passworded admin and default user, choice of MAC-address-based hostname, and joining a domain? As much details as possible for everyone's future reference would be appreciated. WDS isn't a bad choice, but if a Linux-based install can be used, that'd be better.

• Route through site-to-site VPN not working

  - by Jonathan

  I'm trying to set up a site-to-site VPN using RRAS on two 2K8r2 servers since yesterday. The connection is working at this point, but I can't get it to send traffic from one site to the other one. Set up: the set up is the same on both sites: the server is connected to a router that's connected to a modem. The routers act like a DHCP-server and assign IP addresses from the range subnet.21-subnet-.100. Both servers use a static IP address, subnet.11, and are set up as DMZ. Configuration: the servers are configured using the wizard to set up a site-to-site connection. This works with a demand-dial interface and a PPTP VPN connection. As mentioned, the VPN connection work properly. Problem: I can't get the servers to send the traffic for the other site, to be sent through the VPN connection. I added a static route on both server (home, office 1) and I can see the result in the IP routing table (home, office 1). I did this because the route didn't show up automatically. My guess is that this last step isn't right, for example because the routing table states "non demand-dial", which seems not correct. Home: Subnet: 10.0.1.0/24 Router: 10.0.1.1 Server: 10.0.1.11 (DMZ) DHCP: 10.0.1.21-10.0.1.100 RRAS DHCP: 10.0.1.101-10.0.1.150 Office 1: Subnet: 10.0.2.0/24 Router: 10.0.2.1 Server: 10.0.2.11 (DMZ) DHCP: 10.0.2.21-10.0.2.100 RRAS DHCP: 10.0.2.101-10.0.2.150 I hope someone has an idea to get this route working!

• Why cache static files with Varnish, why not pass

  - by Saif Bechan

  I have a system runnning nginx / php-fpm / varnish / wordpress and amazon s3. Now I have looked at a lot of configuration files while setting up the system, and in all of them I found something like this: /* If the request is for pictures, javascript, css, etc */ if (req.url ~ "\.(jpg|jpeg|png|gif|css|js)$") { /* Remove the cookie and make the request static */ unset req.http.cookie; return (lookup); } I do not understand why this is done. Most of the examples also run NginX as a webserver. Now the question is, why would you use the varnish cache to cache these static files. It makes much more sense to me to only cache the dynamic files so that php-fpm / mysql don't get hit that much. Am I correct or am I missing something here? UPDATE I want to add some info to the question based on the answer given. If you have a dynamic website, where the content actually changes a lot, chaching does not make sense. But if you use WordPress for a static website for example, this can be cached for long periods of time. That said, more important to me is static conent. I have found a link with some test and benchmarks on different cache apps and webserver apps. http://nbonvin.wordpress.com/2011/03/14/apache-vs-nginx-vs-varnish-vs-gwan/ NginX is actually faster in getting your static content, so it makes more sense to just let it pass. NginX works great with static files. -- Apart from that, most of the time static content is not even in the webserver itself. Most of the time this content is stores on a CDN somewhere, maybe AWS S3, something like that. I think the varnish cache is the last place where you want to have you static content stored.

• files have no ownership permissions and can't assign ownership

  - by Force Flow

  I'm having problems with file permissions on a server 2008 R1 server. Office 2010 tmp files are being created, and don't have any security permissions assigned. They aren't being deleted, I can't assign ownership, and I can't delete them. I downloaded and ran the sysinternals tool handle.exe. When running it for the first time, handle64.exe was created, but not assigned any permissions. I cannot assign ownership and cannot delete it. Seemingly random files in random places don't seem to have any permissions assigned. Access is denied when attempting to change ownership to administrator or the administrators group. If I try to replace inheritable permissions of the folder these files are in, access is denied for the files with no permissions. I attempted to use subinacl to view the ownership information on the files that had no permissions, but access was denied here as well. I also tried setting the owner with setacl in an elevated cmd window, but access was denied as well. This problem only surfaced in the last few days, and I'm unsure as what the cause is or how to correct it.

• Unattended Kickstart Install

  - by Eric

  I've looked around quite a bit and have seen similar setup and questions, but none seem to work for me. I'm using the following command to create a custom ISO: /usr/bin/livecd-creator --config=/usr/share/livecd-tools/test.ks --fslabel=TestAppliance --cache=/var/cache/live This works great and it creates the ISO with all of the packages and configs I want on it. My issue is that I want the install to be unattended. However, every time I start the CD, it asks for all of the info such as keyboard, time zone, root password, etc. These are my basic settings I have in my kickstart script prior to the packages section. cdrom install autopart autostep xconfig --startxonboot rootpw testpassword lang en_US.UTF-8 keyboard us timezone --utc America/New_York auth --useshadow --enablemd5 selinux --disabled services --enabled=iptables,rsyslog,sshd,ntpd,NetworkManager,network --disabled=sendmail,cups,firstboot,ip6tables clearpart --all So after looking around, I was told that I need to modify my isolinux.cfg file to either do "ks=http://X.X.X.X/location/to/test.ks" or "ks=cdrom:/test.ks". I've tried both methods and it still forces me to go through the install process. When I tail the apache logs on the server, I see that the ISO never even tries to get the file. Below are the exact syntax I'm trying on my isolinux.cfg file. label http menu label HTTP kernel vmlinuz0 append initrd=initrd0.img ks=http://192.168.56.101/files/test.ks ksdevice=eth0 label localks menu label LocalKS kernel vmlinuz0 append initrd=initrd0.img ks=cdrom:/test.ks label install0 menu label Install kernel vmlinuz0 append initrd=initrd0.img root=live:CDLABEL=PerimeterAppliance rootfstype=auto ro liveimg liveinst noswap rd_NO_LUKS rd_NO_MD rd_NO_DM menu default EOF_boot_menu The first 2 give me a "dracut: fatal: no or empty root=" error until I give it a root= option and then it just skips the kickstart completely. The last one is my default option that works fine, but just requires a lot of user input. Any help would be greatly appreciated.

• What is the IPv6 equivalent to IPv4 RFC1918 addresses?

  - by Kumba

  Having a hard time wrapping my head around IPv6 here. A lot of the lingo seems targeted at enterprise-level IPv6 deployments, discussing link-local, site-local, global unicast, scopes, etc. Not a lot of solid information on really small networks, like home networks. I want to check my thinking and make sure I am getting the correct translations from IPv4-speak to IPv6-speak. The first question is, what's the equivalent of RFC1918 for IPv6? Initial searches suggested there was no equivalent. Then I stumbled upon Unique Local Addresses (RFC4193), and that states that all ULA's should be assigned the prefix fc00, followed by a 40-bit random number in the routing prefix. This random number is to "prevent collisions when two IPv6 networks are interconnected" -- again, another reference to an enterprise-level function. If I have a small local LAN at home, numbered using 192.168.4.0/24, what's my equivalent in IPv6's ULA scope? Assuming I will never, ever, tie that IPv6 address into the real internet (a router will NAT & firewall it), can I ignore the RFC to an extent and go with fc00::4:0/120? It also seems that any address in fc00::/7 are to be globally routable. Does this mean I'll need extra protections so my router would not automatically start advertising these private IPv6 addresses to the world? Second question, what's this link-local thing? Reading suggests a default-assigned address in the fe80::/10 range that has the last 64bits of the address comprised of the interface's MAC address. Seems to be required, too, but I'm annoyed by the constant discussion of it in relation to enterprise networks. Third question, what is scope id for? Seems to be yet another term tossed around in relation to enterprise networks, especially when interconnecting them, but almost no explanation on the smaller home network level. Can I see a scope ID AND CIDR notation used together? I.e., fc00::4:0/120%6, or are scope IDs only supposed to be applied to a single /128 IPv6 address?

• No clue for high load average on top

  - by Oz.

  We have several machines on Amazon (ec2) of the type c1.xlarge with 16 cpus, running the Amazon AMI. Details on the machine: 7 GB of memory 20 EC2 Compute Units (8 virtual cores with 2.5 EC2 Compute Units each) 1690 GB of instance storage 64-bit platform I/O Performance: High API name: c1.xlarge One out of the several machines is showing a high load average, since we have run the last yum upgrade a couple of weeks a go. We did not yet update the other machines, and everything looks normal on them. The strange thing is that the top command not showing any hint for the cause of the load.

• My client's solution of a Windows SBS 2011 VM on an Ubuntu host and VirtualBox is pinning the host CPU

  - by Scott Stamp

  Here's my situation, I've got a client hosting two servers (one VM), with the host providing VMware Zimbra, the other Windows Small Business Server 2011. Unfortunately, the person before me had configured this setup as follows. Host: Ubuntu Desktop Edition 10.04 (I know, again, not my choice) running VMware Zimbra 8GB of RAM On-board RAID1 of two 320GB Seagate Barracuda drives for the OS Software RAID5 of four 500GB WD Caviar Black drives on MDADM for bulk storage (sorry, I don't know the model #) A relatively competent quad-core Intel Core i7 CPU from the Nehalem architecture (not suspicious of this as the bottleneck) Guest: Windows Small Business Server 2011 4GB of RAM Host-equivalent CPU allocation VDI file for OS hosted on the on-board RAID, VDI file for storage hosted on the on-board RAID For some reason when running, the VM locks up when sitting nearly idle, and the VirtualBox process reports values of 240%+ in top (how is that even possible?!). Anyone have any ideas or suggestions? I'm totally stumped on this one. Happy to provide whatever logs you'd like to take a look at. Ideally I'd drop VirtualBox and provision this with VMware Workstation, but the client has objected to the (very nominal) costs involved. If hardware needs to be purchased to help, it will be, but we're considering upgrades a last-resort at this time. Thanks in advance! *fingers crossed*

• Recommended open-source firmware for ASUS RT-N16

  - by MasterF

  I have recently acquired an ASUS RT-N16 router. My original plan for it was to install Tomato on it. However, after checking their website i found out that the firmware was not updated in the last 2 years. There seem to be a few updated mods but none of them really seemed mature/stable/well-documented. I would like to know what other people recommend as open-source firmware for this router. I know the answers will probably be subjective; so i will give a bit of background on my needs: for now i will only use the Wi-Fi on an Android phone the connection will not be shared with anyone (so QOS is optional) i want a stable (wired) connection on my PC (for online gaming etc.) i want the (wired) download/upload speeds to be as close as possible to those achieved by directly plugging the Ethernet cable to the PC's network card; i have a 100 Mbps connection my ISP uses PPPOE my technical level: i am a software developer and i have good knowledge of bash scripting, but no experience with networking Also, i know that i could probably just use the stock firmware (and maybe will use it for a while), but i'm interested in trying an open-source version (for more features, flexibility, as a learning exercise etc.)

• mount error 5 = Input/output error

  - by alharaka

  I am running out of ideas. After a long period of testing this morning, I cannot seem to get this to work, and I have no idea why. I want to mount a Windows SMB/CIFS share with a Debian 5.0.4 VM, and it is not cooperating. This the command I am using. debianvm:/home/me# whoami root debianvm:/home/me# smbclient --version Version 3.2.5 debianvm:/home/me# mount -t cifs //hostname.domain.tld/share /mnt/hostname.domain.tld/share --verbose -o user=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD/username mount.cifs kernel mount options: unc=//hostname.domain.tld\share,ip=10.212.15.53,domain=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD,ver=1,rw,user=username,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,pass=*********mount error 5 = Input/output error Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) debianvm:/home/me# The word on the nets has not been very specific, and unfortunately it is almost always environment-specific. I receive no authentication errors. I have tried mount -t smbfs and mount -t cifs, along with smbmount and such. I get the same error before. I doubt it is a problem with DNS resolution, because logging shows the correct IP address. dmesg | tail -f no longer shows authentication errors when I format the domain and username accordingly. I have played a little with iocharset=utf8, file_mode, and dir_mode as described here. That did not help either. I have also tried ntlm and ntlmv2 assuming it might be a minimum auth method problem, but not forcing sec=ntlmv2 it can still authenticate without errors anymore. smbclient -L hostname.domain.tld -W SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD -U username correctly lists all the shares and shows it as the following. Domain=[SUBADDOMAIN] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager] Sharename Type Comment --------- ---- ------- IPC$ IPC Remote IPC ETC$ Disk Remote Administration C$ Disk Remote Administration Share Disk Connection to hostname.domain.tld failed (Error NT_STATUS_CONNECTION_REFUSED) NetBIOS over TCP disabled -- no workgroup available I find the last line intriguing/alarming. Does anyone have any pointers!? Maybe I misread the effin manual.

• How do I migrate Exchange 2007 to new hardware?

  - by Graeme Donaldson

  As per my previous question, I have an Exchange 2007 box which is also a DC. Since I can't demote it while Exchange is installed, I want to move Exchange to a different server. Does anyone have any articles, tips or experiences to share on this? The last time I did this it was with Exchange 2003 and even that is a little rusty in my head. The setup is a single Exchange 2007 Hub/Edge/Mailbox/CAS server. Its currently on Windows Server 2008, I can migrate it to the same OS, or I can go to 2008 R2, I'm not really picky on that. We're running OWA/ActiveSync/POP3(S)/IMAP(S) for client access. I already have another fully functional DC/GC/DNS box in the same site and clients in the site are already using that for DNS. It's also the preferred site bridgehead for AD replication. Update: After reading Evan's answer I realised that my original question wasn't worded correctly. I'm not looking to do a swing migration, I actually need to move Exchange completely over to a new box. I have done swing migrations in the past, i.e. moving over to a temporary box and back to the original hardware afterwards, and I'm not really sure why I used that term in the original question since it's not what I intended. Any tips?

Why Ubuntu is still pointing to open jdk and not to my jdk 7?

• Windows 7 fails to connect to the internet a few minutes after startup

  - by SageTheGreat

  Problem Earlier today, when I turned on my desktop computer, my internet connection works fine. Cryptocurrency miners connecting and hashing as usual and I can browse websites. But after a few minutes, my miner fails indicating that there is something wrong with my internet connection. Tried refreshing my browser and is stuck at "resolving host", and then presented me an error. After that, i can't browse sites anymore. But the weird thing is that the network icon in Windows 7 shows no signs of problems. Solutions Made Restarted my computer without doing anything: Problem persists. Tried using the network troubleshooter of windows: Reported no problems Stopped bonjour still no progress. Loaded windows using Last good config: still no progress. Restarted Modem: No change. Current Status I currently did a system restore to my system to a point before installing the latest update from Microsoft. Because earlier today, I installed some updates and after that, the problem started to appear. (After system restore, same problem.) Latest Programs installed before the problem MS Visual Studio 2013 (but internet still worked fine after the install). I hope someone could provide answers on this problem. It is my first time encountering this. EDIT: Additional Info OS: Windows 7 SP1 64-bit AV: Avast Free Antivirus Internet Connection Type: Ethernet It appears that my Laptop can't even connect to the machine thru Remote Desktop My laptop and phone on WiFi works fine and can connect to the internet. EDIT 2: Whenever I boot into Safe Mode, my Internet is fine.
