• Solaris Fibre Channel target - Configure QLogic QLA2340

  - by growse

  I'm currently trying to set up a small storage system as a fibre channel target. This is for testing, so I'm currently using Solaris (Nexenta) and a QLogic QLA2340 HBA. For some reason, the qlc and qlt drivers don't support the QLA2340, so I'm using the qla2300 driver from QLogic's website. I've also got the scli utility installed for configuration. The HBA is detected by the system. That said, it's not clear how I get from this point to a point where I have a ZFS volume being exposed as an FC target. I was originally following this guide (http://www.youtube.com/watch?v=yzEBd3l7Qn4) but it seems that without the qlc/qlt drivers, Sun's configuration tools won't work. Does that also imply that COMSTAR also won't work? What's the best way to expose an FC target with this setup? Most of the options I'm seeing in scli complain that the port state is LinkDown (it is, I've not plugged anything in yet). Do I have to have my FC client plugged up and working before I can configure the target? Apologies for the slight vagueness of the question, but I'm not overly familiar with the terminology.

• Apache2 with lighttpd as proxy

  - by andrzejp

  Hi, I am using apache2 as web server. I would like to help him lighttpd as a proxy for static content. Unfortunately I can not well set up lighttpd and apache2. (OS: Debian) Important things from lighttpd.config: server.modules = ( "mod_access", "mod_alias", "mod_accesslog", "mod_proxy", "mod_status", ) server.document-root = "/www/" server.port = 82 server.bind = "localhost" $HTTP["remoteip"] =~ "127.0.0.1" { alias.url += ( "/doc/" => "/usr/share/doc/", "/images/" => "/usr/share/images/" ) $HTTP["url"] =~ "^/doc/|^/images/" { dir-listing.activate = "enable" } } I would like to use lighttpd in only one site operating as a virtual directory on apache2. Configuration of this virtual directory: ProxyRequests Off ProxyPreserveHost On ProxyPass /images http://0.0.0.0:82/ ProxyPass /imagehosting http://0.0.0.0:82/ ProxyPass /pictures http://0.0.0.0:82/ ProxyPassReverse / http://0.0.0.0:82/ ServerName MY_VALUES ServerAlias www.MY_VALUES UseCanonicalName Off DocumentRoot /www/MYAPP/forum <Directory "/www/MYAPP/forum"> DirectoryIndex index.htm index.php AllowOverride None ... As you can see (or not;)) my service is physically located at the path: / www / myapp / forum and I would like to support lighttpd dealt with folders: / www / myapp / forum / images / www / myapp / forum / imagehosting / www / myapp / forum / pictures and left the rest (PHP scripts) for apache After running lighttpd and apache2 working party, but did not show up any images of these locations. What is wrong?

• Apple Service Diagnostic application on USB key?

  - by Matt 'Trouble' Esse

  I found the following in a text file, and I would like to use the Apple Service Diagnostic Application from a bootable USB key but I cannot find where to download it or set it up? Also is this free software or does it require a separate licence? It sounds like it would be a useful tool for diagnosing Mac problems. The Apple Service Diagnostic application is designed to run both EFI and Mac OS X tests from an external USB hard drive. Apple Service Diagnostic (EFI) runs low-level tests of the hardware directly and does not require Mac OS X, while Apple Service Diagnostic (OS) uses Mac OS X to run tests. Booting and Using the Apple Service Diagnostic Application - Before using Apple Service Diagnostic, disconnect any Ethernet network, USB, and audio cables. - With the USB hard drive containing ASD 3S123 plugged into a USB port, restart the computer and hold down the option key as the computer boots up into the Startup Manager. To run ASD (EFI) select the "ASD EFI 3S123" drive icon and press return or select it with a mouse click. To run ASD (OS) select the "ASD OS 3S123" drive icon and press return or select it with a mouse click. ASD (EFI) will load in 20-30 seconds; ASD (OS) will load in 2-3 minutes. - After running ASD (OS) or ASD (EFI), press the Restart button to restart the computer back into the normal startup volume, or hold down the option key to get back to the Startup Manager. ASD is no longer delivered as an image to be restored onto a DVD. ASD 3S117 and newer versions requires installation onto an external USB hard drive. For more information, please refer to the document "Installing ASD on a USB hard drive".

• OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

  - by Dogbert

  Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

• LogMeIn Hamachi for Linux

  - by tlunter

  So far most of my work using LogMeIn Hamachi has been from either a Mac OS X or Windows system to Windows or a Linux Computer. Recently I purchased a mini computer and have been running Ubuntu Server on it, as my little server. I knew LogMeIn had a Linux client that is command line only, but I often do all my work via command line anyway, so that wasn't an issue. I added my user to the correct local file so that I could run the hamachi daemon without sudo, and was able to connect to LogMeIn's service. I decided to set up my Linux server as a git server as well, and set it up correctly. The thing is, the server is behind my schools firewall and I need to use hamachi to get around that. Since most of the time I was using either Mac or Windows, I never had an issue sshing onto any of my computers since LogMeIn is fully featured for these OSs. From Linux (Arch) though, it seems like the client cannot correctly route to the LogMeIn IPs. I know from Windows I can connect to the Linux computers, both of them. From Linux (Arch) though, I can't connect to my Mac, Windows, or Linux server. It keeps just dropping the connection. I was wondering if there was some configuration that I would need to make for this to work. I understand that it is most likely going to be a static configuration since I assume it has to do with the computer not understanding that 5.*.*.* actually refers to another IP:Port. Has anyone had any experience getting this to work?

• Possible DNS issue?

  - by durilai

  I am having an issue, which I think stems from DNS. I have 2 servers. Server 1 is AD server with DNS, which was automatically configured when installing AD. The second server is a web server that is part of the domain, but it is not AD nor any other role. I can remote desktop in from server 1 using internal IP address, but when I attempt to connect from any other computer it fails, the computer can connect to server 1. I am able to ping both servers, as well as nslookup both using their FQDN. I am also able to telnet to port 3389. Any help is appreciated UPDATE I do not think it is DNS anymore, but not sure what it is. The remote desktop connects and I get to the login prompt, but when I start to enter credentials it disconnects. I then am unable to reconnect. If I wait for about 10 minutes it will allow me to repeat, but with the same results. UGH!!!

• Make Nginx fail when SSL certificate not present, instead of hopping to only available certificate

  - by Oli

  I've got a bunch of websites on a server, all hosted through nginx. One site has a certificate, the others do not. Here's an example of two sites, using (fairly accurate) representations of real configuration: server { listen 80; server_name ssl.example.com; return 301 https://ssl.example.com$request_uri; } server { listen 443 ssl; server_name ssl.example.com; } server { listen 80; server_name nossl.example.com; } SSL works on ssl.example.com great. If I visit http://nossl.example.com, that works great, but if I try to visit https://nossl.example.com (note the SSL), I get ugly warnings about the certificate being for ssl.example.com. By the sounds of it, because ssl.example.com is the only site listening on port 443, all requests are being sent to it, regardless of domain name. Is there anything I can do to make sure a Nginx server directive only responds to domains it's responsible for?

• USB keyboard stopped working in Ubuntu with error -71

  - by tapan

  I have a usb keyboard which was working perfectly till now (about a year since i have been regularly using ubuntu). It suddenly stopped working. It stopped working when I connected a USB HDD. Now the keyboard works randomly .. working for a while and then stops working for a longer time. Here is the dmesg output : [ 705.817076] usb 5-1: device not accepting address 8, error -71 [ 705.928032] usb 5-1: new low speed USB device using uhci_hcd and address 9 [ 706.336060] usb 5-1: device not accepting address 9, error -71 [ 706.448055] usb 5-1: new low speed USB device using uhci_hcd and address 10 [ 706.568044] usb 5-1: device descriptor read/64, error -71 [ 706.792049] usb 5-1: device descriptor read/64, error -71 [ 707.008060] usb 5-1: new low speed USB device using uhci_hcd and address 11 [ 707.128041] usb 5-1: device descriptor read/64, error -71 [ 707.352052] usb 5-1: device descriptor read/64, error -71 [ 707.456068] hub 5-0:1.0: unable to enumerate USB device on port 1 Based on the suggestions here i tried the following two things: echo -1 > /sys/module/usbcore/parameters/autosuspend echo Y > /sys/module/usbcore/parameters/old_scheme_first However, i am still facing the same problem.

• How do I get a subdomain on Xampp Apache @ localhost?

  - by jasondavis

  **UPDATE- I got it working now, I just had to change to The port number is important here. I just modified my windows HOST file @ C:\Windows\System32\drivers\etc and added this to the end of it 127.0.0.1 images.localhost 127.0.0.1 w-w-w.friendproject-.com 127.0.0.1 friendproject.-com Then I modified my httpd-vhosts.conf file on Apache under Xampp @ C:\webserver\apache\conf\extra Under the part where it shows examples for adding virtualhost I added this code below: NameVirtualHost *:80 <VirtualHost *:80> DocumentRoot /htdocs/images/ ServerName images.localhost </VirtualHost> <VirtualHost *:80> DocumentRoot /htdocs/ ServerName friendproject.com/ </VirtualHost> <VirtualHost *:80> DocumentRoot /htdocs/ ServerName w-ww-.friendproject.c-om/ </VirtualHost> Now the problem is when I go to any of the newly added domains in the browser I get this error below and even worse news is I now get this error even when going to http://localhost/ which worked fine before doing this I realize I can change everything back but I really need to at least get htt-p://im-ages.localhost to work. What do I do? Access forbidden! You don't have permission to access the requested directory. There is either no index document or the directory is read-protected.

• fail2ban log parsing too slow on Raspberry Pi - options? [migrated]

  - by Gordon Morehouse

  I'm running fail2ban on a Raspberry Pi at 950MHz which I cannot overclock further. The Pi is occasionally subject to SYN floods on particular ports. I've set up iptables to throttle the rate of SYNs on the port of interest; when the throttle limits are exceeded, hosts which send SYNs are dropped into the REJECT chain and the particular SYN packet which exceeded the limit is logged. fail2ban then watches for these logged SYNs and, after seeing a few, temporarily bans the host for a short time (this is a transient issue in the app I'm working with). The problem is that the SYN floods can occasionally reach rates which are too fast for fail2ban to keep up with; I'll see 20-40 log messages per second, and eventually fail2ban falls behind and becomes ineffective. To add insult to injury, it continues consuming a LOT of CPU as it tries to catch up. I have verified that DROP chained packets from hosts already banned by fail2ban are not logged, and thus do not add to its load. What are my options here? I have a few ideas, but no clear path forward. Could I make the log-parse regex "easier" so it takes fewer cycles? Would using iptables --log-prefix to put a token near the start of the log message, and/or otherwise simplifying/altering the fail2ban regex help? Here is the current fail2ban config line containing a regex: failregex = kernel:.*?SRC=(?:::f{4,6}:)?(?P<host>[\w\-.^_]+) DST.*?SYN Is there a faster way for fail2ban to watch for the packets exceeding the limits than parsing kern.log? Could fail2ban be run under PyPy instead of CPython with minimal nonstandard wizardry (the OS is Raspbian 7, so, mostly Debian 7)? Is there something better than fail2ban that I could use to watch for the packets which exceed the SYN limits, and after N exceeds in X seconds, temporarily put the offending IP into the iptables DROP bucket, and take it out when the ban timer expires? Again, I'd vastly prefer a solution that uses as much software available in Debian as possible, though I can build Debian packages in a pinch.

• Apache2, Tomcat6, and proxy redirects

  - by Randal Hale

  So here is my question - go easy and slow. I'm a GIS Consultant and general hack with linux. I inherited this volunteer job essentially because I knew more than the rest of the team - or the rest of the team isn't as stubborn as I am... With that said a number of people have been mucking around in the server before I got involved so I've been cleaning up a lot of things. The domain names have been changed to protect the innocent. I have a server running Apache2 (port 80) and tomcat6 (8080) running on ubuntu server 10.4. There is a virtual host on Apache2 called "Runner" (the domain is runner.org). I have mod_proxy loaded. I am trying to redirect everyone that visits runner.org to http://some.ip.address:8080/openrunner-webapp/ So far I've gotten runner.org assigned to the apache2 server. Someone set up a redirect in the httpd.conf file but I believe it needs to go into the virtualhost. I tried setting the redirect in the virtualhost as: *ProxyPass / http://localhost:8080/openrunner-webapp All that does is show me the root of the Apache webserver. Anyway I'm stuck

• iRedMail home setup - use different SMTP relay for different destination domains

  - by John

  Hello helpful server folks, I'm messing with iRedMail. I've mostly been successful, I think I have an SMTP problem. I have changed RoundCube (webmail) to use BrightHouse's, my ISP's, SMTP server for outgoing. It works fine, I click send and poof, I have gmail. I can reply from gmail to my email server, and it works. It took 10 hours for the email to show up, which is a different problem, I think, but it does work. But when I send from my server TO my own server, my ISP's Postmaster account sends me a cryptic blurb. I just got off the phone with them, and they say it "should work", and that they can't reach my pop3 server. (pop3, pop3s, imap, and imaps are all open on my router and forwarded to the server, I'm not sure what I need, I'm just covering my bases...) pop3 and/or imap as external interfaces are just formalities, I really just want webmail to work. Roundcube only takes one SMTP server in its configs. How can I configure Postfix to relay / forward emails to my ISP's SMTP, while taking messages bound for my own domain and processing them? Since my ISP won't let me "bounce" my emails off of it. Maybe I'm vastly misunderstanding how e-mail works in general: To receive mail, I should only need port 25, SMTP, open to the internet, correct? Should I be concerned about some authentication failure from the outside to my relay? (My relay requires user/pass to use, my ISP's requires none.)

• SSL with nginx on subdomain not working

  - by peppergrower

  I'm using nginx to serve three sites: example1.com (which redirects to www.example1.com), example2.com (which redirects to www.example2.com), and a subdomain of example2.com, call it sub.example2.com. This all works fine without SSL. I recently got SSL certs (from StartSSL), one for www.example1.com, one for www.example2.com, and one for sub.example2.com. I got them set up and everything seems to work (I'm using SNI to make all this work on a single IP address), except for sub.example2.com. I can still access it fine over non-SSL, but on SSL I just get a timeout. If I go directly to my server's IP address, I get served the SSL certificate for sub.example2.com, so I know nginx is loading the certificate properly...but somehow it doesn't seem to be listening for sub.example2.com on port 443, even though I told it to. I'm running nginx 1.4.2 on Debian 6 (squeeze); here's my config for sub.example2.com (the other domains have similar configs): server { server_name sub.example2.com; listen 80; listen 443 ssl; ssl_certificate /etc/nginx/ssl/sub.example2.com/server-unified.crt; ssl_certificate_key /etc/nginx/ssl/sub.example2.com/server.key; root /srv/www/sub.example2.com; } Does anything look amiss? What am I missing? I don't know if it matters, but StartSSL lists the base domain as a subject alternative name (SAN); not sure if that would somehow pose problems, if both subdomains list the same SAN.

• Intel DriverInstall issue on HP ProLiant server DL580G5

  - by TomTom

  Given: A HP ProLiant server to be used for Hyper-V server (R 2) Problem: The server has a HP NC364T quad port card, which actually is an Intel 1000 Pro adapter. We are stuck getting this adapter properly working. We need to get it working with: 2 trunks of 2 ports each one of them fully vlan "aware" (without filtering anything - so that Hyper-V can do the VLAN filtering). So far we did: Install the server Install latest PSP. Problem here - tool does not work to set up teaming. We tried to install the latest ProWin pack from Intel - the drivers there are a LOT more current (26th of Marrch 2010, 9.13.41.0). The intalled driver (Microsoft) is ancient (march 2009, 9.13.4.10) A driver update fails both on command line (pnputil) as well as the PortLock device manager executable. No informatoin is provided. the ANS toolset can not create teams (fails with error - again, no reason provided), I know of no logs and the event log has no information either. Questions: What are the best drivers to use? How do we actually install them? How can we then set up teaming and how do we set up the VLAN behavior wanted?

• Window 7 image in vmware will allow network connection out but not http

  - by Ormis

  I am currently trying to create a set of images to deploy on my network, but I've run in to a snag. When I create my own Windows 7 image I can successfully use NAT for connecting to the network but whenever I try to access a webpage I get nothing. To be more specific, All firewalls/iptables are disabled on my host machine, my virtual machine, and my network. I can do lookups and all addresses respond correctly (i'm even using Google's DNS). On the host OS i have full connectivity. On the virtual machine I can ping any device I want and all addresses resolve correctly. Within a browser I cannot reach any page via hostname or IP. I feel almost like port 80 is being blocked but i can't find any reason this would be the case. If anyone has had this occur before, I would love some insight to the problem. I understand this question is a bit out of the norm for stackoverflow, but I've run out of ideas. Thank you for any help you can provide.

• Joining an Ubuntu 14.04 machine to active directory with realm and sssd

  - by tubaguy50035

  I've tried following this guide to set up realmd and sssd with active directory: http://funwithlinux.net/2014/04/join-ubuntu-14-04-to-active-directory-domain-using-realmd/ When I run the command realm –verbose join domain.company.com –user-principal=c-u14-dev1/[email protected] –unattended everything seems to connect. My sssd.conf looks like the following: [nss] filter_groups = root filter_users = root reconnection_retries = 3 [pam] reconnection_retries = 3 [sssd] domains = DOMAIN.COMPANY.COM config_file_version = 2 services = nss, pam [domain/DOMAIN.COMPANY.COM] ad_domain = DOMAIN.COMPANY.COM krb5_realm = DOMAIN.COMPANY.COM realmd_tags = manages-system joined-with-adcli cache_credentials = True id_provider = ad krb5_store_password_if_offline = True default_shell = /bin/bash ldap_id_mapping = True use_fully_qualified_names = True fallback_homedir = /home/%d/%u access_provider = ad My /etc/pam.d/common-auth looks like this: auth [success=3 default=ignore] pam_krb5.so minimum_uid=1000 auth [success=2 default=ignore] pam_unix.so nullok_secure try_first_pass auth [success=1 default=ignore] pam_sss.so use_first_pass # here's the fallback if no module succeeds auth requisite pam_deny.so # prime the stack with a positive return value if there isn't one already; # this avoids us returning an error just because nothing sets a success code # since the modules above will each just jump around auth required pam_permit.so # and here are more per-package modules (the "Additional" block) auth optional pam_cap.so However, when I try to SSH into the machine with my active directory user, I see the following in auth.log: Aug 21 10:35:59 c-u14-dev1 sshd[11285]: Invalid user nwalke from myip Aug 21 10:35:59 c-u14-dev1 sshd[11285]: input_userauth_request: invalid user nwalke [preauth] Aug 21 10:36:10 c-u14-dev1 sshd[11285]: pam_krb5(sshd:auth): authentication failure; logname=nwalke uid=0 euid=0 tty=ssh ruser= rhost=myiphostname Aug 21 10:36:10 c-u14-dev1 sshd[11285]: pam_unix(sshd:auth): check pass; user unknown Aug 21 10:36:10 c-u14-dev1 sshd[11285]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=myiphostname Aug 21 10:36:10 c-u14-dev1 sshd[11285]: pam_sss(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=myiphostname user=nwalke Aug 21 10:36:10 c-u14-dev1 sshd[11285]: pam_sss(sshd:auth): received for user nwalke: 10 (User not known to the underlying authentication module) Aug 21 10:36:12 c-u14-dev1 sshd[11285]: Failed password for invalid user nwalke from myip port 34455 ssh2 What do I need to do to allow active directory users the ability to log in?

• Ubuntu 10.04 Keyboard and Mouse Freezing Problem

  - by nitbuntu

  I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

• Mac OS X Client With Static DHCP Assignment Requests Wrong IP via Option 50

  - by Starchy

  I have a number of Mac (and a few Linux) laptops getting DHCP from a Force10 layer 3 switch, the only DHCP server on the subnet. There's a global dynamic pool, and for each full-time employee's laptop I have a single IP static pool set by MAC address. One and only one of the clients, running OS X 10.7.5, consistently fails to get a static assignment. The MAC address in the static pool definition has been carefully re-checked. Running tcpdump on a mirrored port when the laptop connects, I see that it is specifically requesting 10.100.0.252 (a dynamic address): 11:32:10.108280 IP (tos 0x0, ttl 255, id 28293, offset 0, flags [none], proto UDP (17), length 328) 0.0.0.0.bootpc > broadcasthost.bootps: [udp sum ok] BOOTP/DHCP, Request from 3c:07:54:xx:xx:xx (oui Unknown), length 300, xid 0x1399da89, Flags [none] (0x0000) Client-Ethernet-Address 3c:07:54:xx:xx:xx (oui Unknown) Vendor-rfc1048 Extensions Magic Cookie 0x63825363 DHCP-Message Option 53, length 1: Request Parameter-Request Option 55, length 9: Subnet-Mask, Default-Gateway, Domain-Name-Server, Domain-Name Option 119, LDAP, Option 252, Netbios-Name-Server Netbios-Node MSZ Option 57, length 2: 1500 Client-ID Option 61, length 7: ether 3c:07:54:xx:xx:xx Requested-IP Option 50, length 4: 10.100.0.252 Lease-Time Option 51, length 4: 7776000 Hostname Option 12, length 10: "host-name" END Option 255, length 0 PAD Option 0, length 0, occurs 8 I haven't been able to find any extra system prefs or unusual software on the laptop. Disabling the interface and rebooting or temporarily setting the IP manually both fail to make any difference. Any suggestions appreciated.

• Can't pop3 from exchange server after a reboot

  - by BLAKE

  Last night I shutdown my Exchange 2003 Virtual Machine, I added a new VHD (For backups), and booted it again. Now I can't POP3 email from it with Outlook 2007. In Outlook I get the error: Task '[email protected] - Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).' Does anybody know what is wrong? All I did was a reboot. I haven't formated the added disk. There are no weird errors in the event log. I can still send mail with Outlook over port 25. I can send and recieve mail with OWA. I can POP3 the mail to my phone (it take about 15 minutes after sending a message, but I do get it eventually). EDIT: The 'Microsoft Exchange POP3' Service says that it is started but if I stop it and try to start it again, it fails saying 'Could not start the Microsoft Exchange POP3 service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion.' I did some googling and someone on exchangefreaks.com said that if I use task manager to 'End Task' on inetinfo.exe, then I can start the POP3 service fine. Does anyone know what causes this problem? I am fine for now since I did get the Service started, but If it does this after every reboot...

• Problem using a public key when connecting to a SSH server running on Cygwin

  - by Deleted

  We have installed Cygwin on a Windows Server 2008 Standard server and it working pretty well. Unfortunately we still have a big problem. We want to connect using a public key through SSH which doesn't work. It always falls back to using password login. We have appended our public key to ~/.ssh/authorized_keys on the server and we have our private and public key in ~/.ssh/id_dsa respective ~/.ssh/id_dsa.pub on the client. When debugging the SSH login session we see that the key is offered by the server apparently rejects it by some unknown reason. The SSH output when connecting from an Ubuntu 9.10 desktop with debug information enabled: $ ssh -v 192.168.10.11 OpenSSH_5.1p1 Debian-6ubuntu2, OpenSSL 0.9.8g 19 Oct 2007 debug1: Reading
