  • Cisco ASA (Client VPN) to LAN - through second VPN to second LAN

    - by user50855
    We have 2 site that is linked by an IPSEC VPN to remote Cisco ASAs: Site 1 1.5Mb T1 Connection Cisco(1) 2841 Site 2 1.5Mb T1 Connection Cisco 2841 In addition: Site 1 has a 2nd WAN 3Mb bonded T1 Connection Cisco 5510 that connects to same LAN as Cisco(1) 2841. Basically, Remote Access (VPN) users connecting through Cisco ASA 5510 needs access to a service at the end of Site 2. This is due to the way the service is sold - Cisco 2841 routers are not under our management and it is setup to allow connection from local LAN VLAN 1 IP address 10.20.0.0/24. My idea is to have all traffic from Remote Users through Cisco ASA destined for Site 2 to go via the VPN between Site 1 and Site 2. The end result being all traffic that hits Site 2 has come via Site 1. I'm struggling to find a great deal of information on how this is setup. So, firstly, can anyone confirm that what I'm trying to achieve is possible? Secondly, can anyone help me to correct the configuration bellow or point me in the direction of an example of such a configuration? Many Thanks. interface Ethernet0/0 nameif outside security-level 0 ip address 7.7.7.19 255.255.255.240 interface Ethernet0/1 nameif inside security-level 100 ip address 10.20.0.249 255.255.255.0 object-group network group-inside-vpnclient description All inside networks accessible to vpn clients network-object 10.20.0.0 255.255.255.0 network-object 10.20.1.0 255.255.255.0 object-group network group-adp-network description ADP IP Address or network accessible to vpn clients network-object 207.207.207.173 255.255.255.255 access-list outside_access_in extended permit icmp any any echo-reply access-list outside_access_in extended permit icmp any any source-quench access-list outside_access_in extended permit icmp any any unreachable access-list outside_access_in extended permit icmp any any time-exceeded access-list outside_access_in extended permit tcp any host 7.7.7.20 eq smtp access-list outside_access_in extended permit tcp any host 7.7.7.20 eq https access-list outside_access_in extended permit tcp any host 7.7.7.20 eq pop3 access-list outside_access_in extended permit tcp any host 7.7.7.20 eq www access-list outside_access_in extended permit tcp any host 7.7.7.21 eq www access-list outside_access_in extended permit tcp any host 7.7.7.21 eq https access-list outside_access_in extended permit tcp any host 7.7.7.21 eq 5721 access-list acl-vpnclient extended permit ip object-group group-inside-vpnclient any access-list acl-vpnclient extended permit ip object-group group-inside-vpnclient object-group group-adp-network access-list acl-vpnclient extended permit ip object-group group-adp-network object-group group-inside-vpnclient access-list PinesFLVPNTunnel_splitTunnelAcl standard permit 10.20.0.0 255.255.255.0 access-list inside_nat0_outbound_1 extended permit ip 10.20.0.0 255.255.255.0 10.20.1.0 255.255.255.0 access-list inside_nat0_outbound_1 extended permit ip 10.20.0.0 255.255.255.0 host 207.207.207.173 access-list inside_nat0_outbound_1 extended permit ip 10.20.1.0 255.255.255.0 host 207.207.207.173 ip local pool VPNPool 10.20.1.100-10.20.1.200 mask 255.255.255.0 route outside 0.0.0.0 0.0.0.0 7.7.7.17 1 route inside 207.207.207.173 255.255.255.255 10.20.0.3 1 crypto ipsec transform-set ESP-3DES-SHA esp-3des esp-sha-hmac crypto ipsec security-association lifetime seconds 28800 crypto ipsec security-association lifetime kilobytes 4608000 crypto dynamic-map outside_dyn_map 20 set transform-set ESP-3DES-SHA crypto dynamic-map outside_dyn_map 20 set security-association lifetime seconds 288000 crypto dynamic-map outside_dyn_map 20 set security-association lifetime kilobytes 4608000 crypto dynamic-map outside_dyn_map 20 set reverse-route crypto map outside_map 20 ipsec-isakmp dynamic outside_dyn_map crypto map outside_map interface outside crypto map outside_dyn_map 20 match address acl-vpnclient crypto map outside_dyn_map 20 set security-association lifetime seconds 28800 crypto map outside_dyn_map 20 set security-association lifetime kilobytes 4608000 crypto isakmp identity address crypto isakmp enable outside crypto isakmp policy 20 authentication pre-share encryption 3des hash sha group 2 lifetime 86400 group-policy YeahRightflVPNTunnel internal group-policy YeahRightflVPNTunnel attributes wins-server value 10.20.0.9 dns-server value 10.20.0.9 vpn-tunnel-protocol IPSec password-storage disable pfs disable split-tunnel-policy tunnelspecified split-tunnel-network-list value acl-vpnclient default-domain value YeahRight.com group-policy YeahRightFLVPNTunnel internal group-policy YeahRightFLVPNTunnel attributes wins-server value 10.20.0.9 dns-server value 10.20.0.9 10.20.0.7 vpn-tunnel-protocol IPSec split-tunnel-policy tunnelspecified split-tunnel-network-list value YeahRightFLVPNTunnel_splitTunnelAcl default-domain value yeahright.com tunnel-group YeahRightFLVPN type remote-access tunnel-group YeahRightFLVPN general-attributes address-pool VPNPool tunnel-group YeahRightFLVPNTunnel type remote-access tunnel-group YeahRightFLVPNTunnel general-attributes address-pool VPNPool authentication-server-group WinRadius default-group-policy YeahRightFLVPNTunnel tunnel-group YeahRightFLVPNTunnel ipsec-attributes pre-shared-key *

  • MSI Installer error 2203; how to force permissions on installer directory?

    - by goober
    [Cross-Posted on StackOverflow.com as well because the question relates to development. Feel free to let me know where it best belongs.] Hi all, I'll try to bullet-point to keep it short: Background / Issue Trying to install ASP.NET MVC 3 RC on my Windows 7 machine. Uninstalled other versions of MVC (2 and 3 Beta 1). Ran the installer -- got a generic error, 2203. Log files said that it was a permissions error on C:\Windows\Installer. Checked C:\Windows\Installer -- sure enough, it's marked as read-only. I un-checked "Read-Only" in the folder properties and applied. It appears to open the dialog and apply to all files. However, when clicking properties again, the read-only box is backed to checked. Checked the security tab of the folder -- both system and the Administrators group have full access. I checked ownership -- the Administrators group is listed as an owner. Verified that I'm in the system as an Administrator (in fact, the only account in the Administrators group besides Administrator). So, what gives? Thanks in advance for any help you can provide!

  • CoreStore Encryption Error on Mac Lion

    - by Michael
    I am trying to encrypt an external drive using diskutil CoreStorage on Mac Lion 10.7.4. I thought the only requirements were that the drive have GUID partition scheme and Journaled HFS+ file system.

  • Windows 2008 R2 SMB / CIFS Logging to diagnose Brother MFC Network Scanning

    - by Steven Potter
    I am attempting to setup network scanning on a brother MFC-9970CDW printer. According to the Brother documentation, the printer is setup to connect to any CIFS network share. I applied all of the appropriate setting in the printer however I get a "sending error" when I try to scan a document. When I look at the logs of the 2008 R2 server that I am attempting to connect to; I can see in the security log where the printer successfully authenticates, however nothing else is logged. I would assume that immediately after the authentication, the printer is making a CIFS request and some sort of error is occurring, however I can't seem to find any way to log this information to find out what is going on. Is it possible to get Windows 2008 to log SMB/CIFS traffic? Followup: I installed Microsoft netmon and captured the packets associated with the transaction: 510 3:04:28 PM 7/9/2012 34.4277743 System 192.168.1.134 192.168.1.10 SMB SMB:C; Negotiate, Dialect = NT LM 0.12 {SMBOverTCP:30, TCP:29, IPv4:22} 511 3:04:28 PM 7/9/2012 34.4281246 System 192.168.1.10 192.168.1.134 SMB SMB:R; Negotiate, Dialect is NT LM 0.12 (#0), SpnegoToken (1.3.6.1.5.5.2) {SMBOverTCP:30, TCP:29, IPv4:22} 519 3:04:29 PM 7/9/2012 34.8986214 System 192.168.1.134 192.168.1.10 SMB SMB:C; Session Setup Andx, NTLM NEGOTIATE MESSAGE {SMBOverTCP:30, TCP:29, IPv4:22} 520 3:04:29 PM 7/9/2012 34.8989310 System 192.168.1.10 192.168.1.134 SMB SMB:R; Session Setup Andx, NTLM CHALLENGE MESSAGE - NT Status: System - Error, Code = (22) STATUS_MORE_PROCESSING_REQUIRED {SMBOverTCP:30, TCP:29, IPv4:22} 522 3:04:29 PM 7/9/2012 34.9022870 System 192.168.1.134 192.168.1.10 SMB SMB:C; Session Setup Andx, NTLM AUTHENTICATE MESSAGEVersion:v2, Domain: CORP, User: PRINTSUPOFF, Workstation: BRN001BA9AD1FE6 {SMBOverTCP:30, TCP:29, IPv4:22} 523 3:04:29 PM 7/9/2012 34.9032421 System 192.168.1.10 192.168.1.134 SMB SMB:R; Session Setup Andx {SMBOverTCP:30, TCP:29, IPv4:22} 525 3:04:29 PM 7/9/2012 34.9051855 System 192.168.1.134 192.168.1.10 SMB SMB:C; Tree Connect Andx, Path = \\192.168.1.10\IPC$, Service = ????? {SMBOverTCP:30, TCP:29, IPv4:22} 526 3:04:29 PM 7/9/2012 34.9053083 System 192.168.1.10 192.168.1.134 SMB SMB:R; Tree Connect Andx, Service = IPC {SMBOverTCP:30, TCP:29, IPv4:22} 528 3:04:29 PM 7/9/2012 34.9073573 System 192.168.1.134 192.168.1.10 DFSC DFSC:Get DFS Referral Request, FileName: \\192.168.1.10\NSCFILES, MaxReferralLevel: 3 {SMB:33, SMBOverTCP:30, TCP:29, IPv4:22} 529 3:04:29 PM 7/9/2012 34.9152042 System 192.168.1.10 192.168.1.134 SMB SMB:R; Transact2, Get Dfs Referral - NT Status: System - Error, Code = (549) STATUS_NOT_FOUND {SMB:33, SMBOverTCP:30, TCP:29, IPv4:22} 531 3:04:29 PM 7/9/2012 34.9169738 System 192.168.1.134 192.168.1.10 SMB SMB:C; Tree Disconnect {SMBOverTCP:30, TCP:29, IPv4:22} 532 3:04:29 PM 7/9/2012 34.9170688 System 192.168.1.10 192.168.1.134 SMB SMB:R; Tree Disconnect {SMBOverTCP:30, TCP:29, IPv4:22} As you can see, the DFS referral fails and the transaction is shut down.

  • How do I force Windows 7 to recognize my Projector?

    - by user63564
    I have a new Dell XPS with an NVIDIA GeForce GT 445M and an old (several years) Epson PowerLite Cinema 550 projector. Windows 7 refuses to recognize that the projector is connected under normal conditions (I'll get to the strange condition in a moment). Here are some things that I have already tried: Confirm that the projector continues to work well on my old Windows XP laptop. Confirm that the video cable (HDMI to HDMI) is connected Make sure the Dell laptop is plugged in to wall power at all times Reboot both the computer and the projector Click "Detect" under the "Connect to an External Display" Windows dialog (no reaction) Click "Rigorous Display Detection" under NVIDIA Control Panel (dialog: none found) Checked "Force Television Detection on startup" under "My display is not shown..." in NVIDIA Control Panel (no effect) Here's where it gets weird... My projector has three states: off, standby and on. Standby means the power switch on the back is on, but the projector is effectively off (no picture, no access to menu or controls). When I plug in the HDMI cable while the projector is in standby, Windows detects the projector! It lets me switch to Duplicate, Extend, or Project Only mode, and adjusts the resolution appropriately. A new Generic Plug-n-Play monitor shows up in my device manager. A "Seiko EPSON PJ" display shows up in my NVIDIA control panel. Then if I turn my projector on, Windows no longer recognizes the display. This is true whether I turn the projector on while the HDMI cable is plugged in, or if I unplug the HDMI cable while turning on the projector. Anyone have any ideas, because I'm completely stumped...?

  • disk-to-disk backup without costly backup redundancy?

    - by AaronLS
    A good backup strategy involves a combination of 1) disconnected backups/snapshots that will not be affected by bugs, viruses, and/or security breaches 2) geographically distributed backups to protect against local disasters 3) testing backups to ensure that they can be restored as needed Generally I take an onsite backup daily, and an offsite backup weekly, and do test restores periodically. In the rare circumstance that I need to restore files, I do some from the local backup. Should a catastrophic event destroy the servers and local backups, then the offsite weekly tape backup would be used to restore the files. I don't need multiple offsite backups with redundancy. I ALREADY HAVE REDUNDANCY THROUGH THE USE OF BOTH LOCAL AND REMOTE BACKUPS. I have recovery blocks and par files with the backups, so I already have protection against a small percentage of corrupt bits. I perform test restores to ensure the backups function properly. Should the remote backups experience a dataloss, I can replace them with one of the local backups. There are historical offsite backups as well, so if a dataloss was not noticed for a few weeks(such as a bug/security breach/virus), the data could be restored from an older backup. By doing this, the only scenario that poses a risk to complete data loss would be one where both the local, remote, and servers all experienced a data loss in the same time period. I'm willing to risk that happening since the odds of that trifecta negligibly small, and the data isn't THAT valuable to me. So I hope I have emphasized that I don't need redundancy in my offsite backups because I have covered all the bases. I know this exact technique is employed by numerous businesses. Of course there are some that take multiple offsite backups, because the data is so incredibly valuable that they don't even want to risk that trifecta disaster, but in the majority of cases the trifecta disaster is an accepted risk. I HAD TO COVER ALL THIS BECAUSE SOME PEOPLE DON'T READ!!! I think I have justified my backup strategy and the majority of businesses who use offsite tape backups do not have any additional redundancy beyond what is mentioned above(recovery blocks, par files, historical snapshots). Now I would like to eliminate the use of tapes for offsite backups, and instead use a backup service. Most however are extremely costly for $/gb/month storage. I don't mind paying for transfer bandwidth, but the cost of storage is way to high. All of them advertise that they maintain backups of the data, and I imagine they use RAID as well. Obviously if you were using them to host servers this would all be necessary, but for my scenario, I am simply replacing my offsite backups with such a service. So there is no need for RAID, and absolutely no value in another layer of backups of backups. My one and only question: "Are there online data-storage/backup services that do not use redundancy or offer backups(backups of my backups) as part of their packages, and thus are more reasonably priced?" NOT my question: "Is this a flawed strategy?" I don't care if you think this is a good strategy or not. I know it pretty standard. Very few people make an extra copy of their offsite backups. They already have local backups that they can use to replace the remote backups if something catastrophic happens at the remote site. Please limit your responses to the question posed. Sorry if I seem a little abrasive, but I had some trolls in my last post who didn't read my requirements nor my question, and were trying to go off answering a totally different question. I made it pretty clear, but didn't try to justify my strategy, because I didn't ask about whether my strategy was justifyable. So I apologize if this was lengthy, as it really didn't need to be, but since there are so many trolls here who try to sidetrack questions by responding without addressing the question at hand.

  • strange Postfix logwatch log summary on my ubuntu vps

    - by DannyRe
    Hi I would be very thankful if someone could help me on explaining this logwatch summary of my postfix installation on my ubuntu 10.04 vps. I dont really know if this might be a normal log file because of the many authentication failed entries and foreign IP addresses. Any advise for a novice?

  • Use synergy with Physical KVM

    - by Mr. Man
    I am using synergy on a Linux Mint computer as the server with a Mac as the client. I also have a physical KVM switch. The problem I have is that when ever I switch the physical KVM to my Mac, synergy stops working as in the keyboard and mouse don't work with the Mac. Thanks in advance!

  • How does Subnetting Work?

    - by Kyle Brandt
    How does Subnetting Work, and How do you do it by hand or in your head? Can someone explain both conceptually and with several examples? Server Fault gets lots of subnetting homework questions, so we could use an answer to point them to on Server Fault itself. What is classless routing and why is class-based routing obsolete? If I have a network, how do I figure out how to split it up? If I am given a netmask, how do I know what the network Range is for it? Sometimes there is a slash followed by a number, what is that number? Sometimes there is a subnet mask, but also a wildcard mask, they seem like the same thing but they are different? Someone mentioned something about knowing binary for this? Not looking for links to other sites (unless maybe you have one post with a bunch of good ones). I already know how to subnet, I just thought it would be nice if Server Fault had a generic subnetting answer.

  • Custom fail2ban Filter for phpMyadmin bruteforce attempts

    In my quest to block excessive failed phpMyAdmin login attempts with fail2ban, I've created a script that logs said failed attempts to a file: /var/log/phpmyadmin_auth.log Custom log The format of the /var/log/phpmyadmin_auth.log file is: phpMyadmin login failed with username: root; ip: 192.168.1.50; url: http://somedomain.com/phpmyadmin/index.php phpMyadmin login failed with username: ; ip: 192.168.1.50; url: http://192.168.1.48/phpmyadmin/index.php Custom filter [Definition] # Count all bans in the logfile failregex = phpMyadmin login failed with username: .*; ip: <HOST>; phpMyAdmin jail [phpmyadmin] enabled = true port = http,https filter = phpmyadmin action = sendmail-whois[name=HTTP] logpath = /var/log/phpmyadmin_auth.log maxretry = 6 The fail2ban log contains: 2012-10-04 10:52:22,756 fail2ban.server : INFO Stopping all jails 2012-10-04 10:52:23,091 fail2ban.jail : INFO Jail 'ssh-iptables' stopped 2012-10-04 10:52:23,866 fail2ban.jail : INFO Jail 'fail2ban' stopped 2012-10-04 10:52:23,994 fail2ban.jail : INFO Jail 'ssh' stopped 2012-10-04 10:52:23,994 fail2ban.server : INFO Exiting Fail2ban 2012-10-04 10:52:24,253 fail2ban.server : INFO Changed logging target to /var/log/fail2ban.log for Fail2ban v0.8.6 2012-10-04 10:52:24,253 fail2ban.jail : INFO Creating new jail 'ssh' 2012-10-04 10:52:24,253 fail2ban.jail : INFO Jail 'ssh' uses poller 2012-10-04 10:52:24,260 fail2ban.filter : INFO Added logfile = /var/log/auth.log 2012-10-04 10:52:24,260 fail2ban.filter : INFO Set maxRetry = 6 2012-10-04 10:52:24,261 fail2ban.filter : INFO Set findtime = 600 2012-10-04 10:52:24,261 fail2ban.actions: INFO Set banTime = 600 2012-10-04 10:52:24,279 fail2ban.jail : INFO Creating new jail 'ssh-iptables' 2012-10-04 10:52:24,279 fail2ban.jail : INFO Jail 'ssh-iptables' uses poller 2012-10-04 10:52:24,279 fail2ban.filter : INFO Added logfile = /var/log/auth.log 2012-10-04 10:52:24,280 fail2ban.filter : INFO Set maxRetry = 5 2012-10-04 10:52:24,280 fail2ban.filter : INFO Set findtime = 600 2012-10-04 10:52:24,280 fail2ban.actions: INFO Set banTime = 600 2012-10-04 10:52:24,287 fail2ban.jail : INFO Creating new jail 'fail2ban' 2012-10-04 10:52:24,287 fail2ban.jail : INFO Jail 'fail2ban' uses poller 2012-10-04 10:52:24,287 fail2ban.filter : INFO Added logfile = /var/log/fail2ban.log 2012-10-04 10:52:24,287 fail2ban.filter : INFO Set maxRetry = 3 2012-10-04 10:52:24,288 fail2ban.filter : INFO Set findtime = 604800 2012-10-04 10:52:24,288 fail2ban.actions: INFO Set banTime = 604800 2012-10-04 10:52:24,292 fail2ban.jail : INFO Jail 'ssh' started 2012-10-04 10:52:24,293 fail2ban.jail : INFO Jail 'ssh-iptables' started 2012-10-04 10:52:24,297 fail2ban.jail : INFO Jail 'fail2ban' started When I issue: sudo service fail2ban restart fail2ban emails me to say ssh has restarted, but I receive no such email about my phpmyadmin jail.

  • saslauthd authentication error

    - by James
    My server has developed an expected problem where I am unable to connect from a mail client. I've looked at the server logs and the only thing that looks to identify a problem are events like the following: Nov 23 18:32:43 hig3 dovecot: imap-login: Login: user=, method=PLAIN, rip=xxxxxxxx, lip=xxxxxxx, TLS Nov 23 18:32:55 hig3 postfix/smtpd[11653]: connect from xxxxxxx.co.uk[xxxxxxx] Nov 23 18:32:55 hig3 postfix/smtpd[11653]: warning: SASL authentication failure: cannot connect to saslauthd server: No such file or directory Nov 23 18:32:55 hig3 postfix/smtpd[11653]: warning: xxxxxxx.co.uk[xxxxxxxx]: SASL LOGIN authentication failed: generic failure Nov 23 18:32:56 hig3 postfix/smtpd[11653]: lost connection after AUTH from xxxxxxx.co.uk[xxxxxxx] Nov 23 18:32:56 hig3 postfix/smtpd[11653]: disconnect from xxxxxxx.co.uk[xxxxxxx] The problem is unusual, because just half an hour previously at my office, I was not being prompted for a correct username and password in my mail client. I haven't made any changes to the server, so I can't understand what would have happened to make this error occur. Searches for the error messages yield various results, with 'fixes' that I'm uncertain of (obviously don't want to make it worse or fix something that isn't broken). When I run testsaslauthd -u xxxxx -p xxxxxx I also get the following result: connect() : No such file or directory But when I run testsaslauthd -u xxxxx -p xxxxxx -f /var/spool/postfix/var/run/saslauthd/mux -s smtp I get: 0: OK "Success." I found those commands on another forum and am not entirely sure what they mean, but I'm hoping they might give an indication of where the problem might lie. If it makes any difference, I'm running Ubuntu 10.04.1, Postfix 2.7.0 and Webmin/ Virtualmin.

  • MediaWiki Math Extension Out of Sync

    - by kfmfe04
    I am trying to run MediaWiki 1.19.2 on Ubuntu Linux (3.0.0-26-generic #42-Ubuntu AMD 64). It installs fine via tar.gz, however, I run into problems when trying to install the Math extension (via git clone from its repository). I get the following error in the Apache logs: PHP Fatal error: Call to undefined method FSFileBackend::getRootStoragePath() in /var/www/abc.com/html/mediawiki-1.19.2/extensions/Math/Math.body.php on line 361, referer: http://intra.abc.com/wiki/index.php?title=Quality&action=submit so apparently, the latest Math extension is out-of-sync with MediaWiki 1.19.2; the latest Math extension is apparently using post-1.19.2 methods. I tried looking through the git logs for some indication (a tag, perhaps?) of which revision of Math worked with 1.19.2, but no luck. Anyone have any suggestions? Thanks in advance. Edit: Just my luck - after posting this message, I found this link. I think this version should do the job. Consider this question closed/answered.

However, within the last week or so (not really sure when) I started getting the below error whenever attempting to send an email: Jul 20 07:40:46 localhost postfix/smtp[11958]: connect to smtp.gmail.com[2001:4860:800a::6c]:587: Network is unreachable Jul 20 07:40:46 localhost postfix/smtp[11958]: connect to smtp.gmail.com[173.194.76.109]:587: Connection refused Jul 20 07:40:46 localhost postfix/smtp[11958]: connect to smtp.gmail.com[173.194.76.108]:587: Connection refused Here is my configuration file: # See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

  • pure-ftpd not listening on specified port

    - by Jason McLaren
    I installed the pure-ftpd package (version 1.0.35-1) on an Ubuntu 12.04 box (an EC2 instance based on the standard Ubuntu 12.04 AMI). The pure-ftpd daemon is running (verified with ps), though there is no PID file (expected one to be created by the /etc/init.d/pure-ftpd script). Here's the resulting command that gets run by the init.d script: /usr/sbin/pure-ftpd -l pam -O clf:/var/log/pure-ftpd/transfer.log -o -8 UTF-8 -u 1000 -E -B -g /var/run/pure-ftpd/pure-ftpd.pid Here's my real problem: the ftp server isn't actually listening on any port (checked with netstat and nmap). So I can't ftp to the server (either locally using localhost or remotely using the public IP address). I tried adding a Bind file to /etc/pure-ftpd/conf and restarting, but it didn't help. When I installed pure-ftpd, it replaced inetd with openbsd-inetd, but did not run it since there were no services enabled. So inetd is not listening on port 21 either. (Apparently Ubuntu has a no-inetd-by-default policy, according to https://lists.ubuntu.com/archives/ubuntu-users/2010-September/227905.html .) I want to run pure-ftpd by itself (not with inetd) anyways, since the /etc/init.d/pure-ftpd script requires no inetd if you use the UploadScript feature. I'm not familiar with how Ubuntu handles network services (and can't find any relevant docs besides generic man pages), so I'm probably missing something obvious. Nothing seems out of the ordinary with /etc/hosts.allow (empty) or hosts.deny (empty), and I didn't add any firewall rules (iptables -L shows that the firewall is in its initial state). I've checked the pure-ftpd docs; not sure what else to look at. Any help would be appreciated, thanks!

  • Resolving "JBoss Web Console is Accessible to Unauthenticated Remote Users" vulnerability

    - by IAmJeff
    Our security team has determined there is a vulnerability in one of our systems. We are using version JBoss 5.1.0GA on RHEL 5.10. Vulnerability description: JBoss Web Console is Accessible to Unauthenticated Remote Users Yes, this looks familiar. Refer to Question 501417. I do not find the answer there complete. Can someone (or multiple someones) answer Does a newer version of JBoss fix this vulnerability? Are there links describing, in more detail, manual modification of JBoss configuration files to resolve the issue? Are there others options to remediate this vulnerability? Why don't I find the other answer complete? I'm not at all familiar with JBoss, so this answer seems a bit too simple. The web-console.war contains commented-out templates for basic security in its WEB-INF/web.xml as well as commented-out setup for a security domain in WEB-INF/jboss-web.xml. Just uncomment those basic security blocks and restart? Is there anything else I need to include? This seems generic. Do I need to include anything about my environment, such as absolute paths, etc.? Am I making this too complicated?

  • VPN Error 619: Behind Cisco Router WRT310N

    - by ty91011
    I've researched a lot on all the forums and this error is too generic for any of the proposed solutions to work. I'll try to give as much detail and tried solutions. I'm running a CentOS PPTP server behind a Cisco WRT310N Router. Multiple clients from outside with different OS have failed with the same error 619, along with turning off windows firewall and disabling antivirus. I believe this is a router and IP routing issue, and not a client issue. When I connect from a client on the same router as the VPN server, it works when I use the 192. network address- but doesn't work with the public IP address. I've tried telnet to port 1723 from an outside server and I get in. I've opened up the VPN port (1723) on the router, VPN udp port (500), and the GRE port (47) to route to the VPN server's ip. Also, the server's router is behind a DSL modem. I had a glimmer of hope when this site: http://www.chicagotech.net/casestudy/vpnerror619.htm suggested that the PPoE authentication should reside on the router and not the modem. But I still came up empty. So does anybody know what the problem is?

  • Video card not detected on Lenovo T410 in Linux

    - by wich
    I have a T410 with an nVidia NVS 3100M, this is not a hybrid system, there is no Optimus. (No option in the BIOS for Optimus, lspci in linux as well as the Windows device manager only show the nVidia) Using lspci I see the GPU as a present device, however, I can not, for the life of me, get any video driver to work that will let me start an X session, every time X craps out with the error (EE) No devices detected. I have tried the nVidia binary blob, (with nvidia-config, made sure no nvidia support in the kernel), I have tried nouveau, I have tried nv, I have even tried generic vesa, nothing will work. When I compare the dmesg that I get when loading the nvidia kernel module, I see that it is missing some lines compared with another system that also has an nvidia card, specifically the line mentioning the GPU name (3100M) is not there. I have checked every option in the BIOS, there is nothing to control except for the BIOS video output port, which is set to the LCD panel. I have no idea anymore what the problem may be, or even how I can diagnose this problem further. Any help will be appreciated.

  • Editing a windows XP installation's registry without being able to log in.

    - by Alain
    I've got a windows XP installation that has a corrupt registry. A worm (which was removed) had hijacked the HKLM\Software\Microsoft\Windows NT\CurrentVersion\Winlogon entry (which should have a value of Userinit=C:\windows\system32\userinit.exe When the worm was removed, the corrupt entry was deleted entirely, and now the system automatically logs off immediately after attempting to log in. Regardless of the user and boot mode, no accounts can be logged in to. The only thing required to correct this behavior is to restore the registry key, but I cannot come up with any ways of editing the registry without logging in to an account. I tried remotely connecting to the registry but the required services aren't enabled on the machine. I tried booting on the same machine using the BartPE boot CD but I could not find any way of editing the registry on the C:\Windows installation - running regedit only modifies the X:\I386\ registry in memory. So, what can I use modify the registry of an un-login-able Windows XP instance so that I can log in again? Thanks guys. EDIT: The fix worked. The solution to the auto-logoff problem was, as hoped, to simply add the value mentioned above to the appropriate registry entry. This can be done using the BartPE Boot CD, as described in the accepted answer below, but I used the Offline NT Registry Editor software mentioned in another answer. The steps were: Boot from the NT Registry Editor CD Follow the directions until the appropriate boot sector is loaded. Instead of using one of the default options for modifying passwords or user accounts, type "software" to edit that hive. Type '9' to enter the command line based registry editor. Type "cd Microsoft" (enter) "cd Windows NT" (enter) "cd CurrentVersion" (enter) "cd Winlogon" (enter) Type "nv 1 Userinit" to create a new value under the Winlogon key Type "ev Userinit" to edit the new value, and when prompted, type "C:\windows\system32\userinit.exe" (enter) Type 'q' to quit the registry editor, and as you back out of the system, follow directions to write the hive back to disk. Restart your computer and log in - problem solved. (generic 'warning: back up your registry' disclaimer)

  • How to find cause of main file system going to read only mode

    - by user606521
    Ubuntu 12.04 File system goes to readonly mode frequently. First of all I have read this question file system is going into read only mode frequently already. But I have to know if it's not caused by something else than dying hard drive. This is server provided by my client and I am just runing there some node.js workers + one node.js server and I am using mongodb. From time to time (every 20-50h) system suddenly makes filesystem read only, mongodb process fails (due read-only fs) and my node workers/server (which are started by forever) are just killed. Here is the log from dmesg - I can see there some errors and messages that FS is going to read-only, and there is also some JOURNAL error but I would like to find cause of those errors.. http://speedy.sh/Ux2VV/dmesg.log.txt edit smartctl -t long /dev/sda smartctl 5.41 2011-06-09 r3365 [x86_64-linux-3.5.0-23-generic] (local build) Copyright (C) 2002-11 by Bruce Allen, http://smartmontools.sourceforge.net SMART support is: Unavailable - device lacks SMART capability.

  • Blank desktop when logging into a Virtualized Windows 2008 Terminal Server?

    - by Rachel
    We have a Virtualized Terminal Server running Windows Server 2008. When the admin user logs in, everything is fine. When anyone else logs in, their desktop and start menu is blank (they have the taskbar, start button, and quick launch links though). If I go into Windows Explorer, I can see icons in their desktop folder (although the icon image is missing and it is just displaying the generic icon), but can't run any of them. If I login with a user that is part of the Administrator group in Active directory, I get the same behavior except I can launch the programs found in the Desktop Folder of Windows Explorer. I cannot drag these items out onto the desktop though - The cursor doesn't allow me to drop them. From Task Manager I can see that explorer.exe and dwm.exe are both running. The Authenticated Users and Interactive groups are both under the Users group, along with our network's Domain Users group. Does anyone know why this is happening and how I can fix it? Also, not sure if it's related but about 1 in every 3 logins just hangs at a completely blank blue screen (no start button, taskbar, or quick launch buttons) and needs to be disconnected / reset by an admin. Edit I just noticed that the desktop itself doesn't even respond to click events. It's almost like the entire desktop is missing. At first I thought it didn't respond to right-click events because of an AD policy, but then I noticed if you open the Start Menu and click the desktop, the start menu doesn't shut like it should

  • Get details / solve issue with a kernel panic?

    - by Joseph
    I have a Lenovo T430 running Linux Mint 13 (MATE): joseph:~$ uname -a Linux joseph-T430-LM 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux I installed Mint immediately after getting the laptop about two weeks ago, and have noticed that about once a day, the computer will completely freeze up- I can't use Ctrl+Alt+Backspace to restart X, I can't use Ctrl+Alt+F1 to get a text only terminal, can't move mouse, can't type, and if any music was playing it just gets stuck in about a 1-second loop. There is a Windows partition, but I haven't had any issues in Windows. I couldn't find a common thread between the freezes, they were seemingly random (sometimes right after I clicked the mouse, sometimes not; sometimes with Pandora/flash being used, sometimes not, etc). I assume they're kernel panics since it completely locks up, but the laptop doesn't have a capslock or scroll lock LED. It is on a dock and I do have a USB keyboard, but the scroll lock/capslock lights do not flash when it happens (not sure if this is indicating its not a kernel panic, or if the kernel panic just wouldn't illuminate the LEDs on a usb keyboard attached to a laptop dock). This was annoying but not terrible. However, I've found a way to reproduce it. I have a particular CSV file that when I open up in LibreOffice Calc and scroll around, the same thing happens- complete lock up. I really need to use this file, so I'd like to fix the issue, but at the least it's given me a test case to work with. So, having a case where I can cause this issue, what can I do to better find out what's going on? I've looked in /var/log/syslog but haven't found anything seemingly useful. Any thoughts?
