Active FTP connections failure through a PIX 7.2.1

• Active FTP problem between Checkpoint and Cisco PIX

  Hello

  I am facing a strange problem.

  Many of our customers have achieved a Checkpoint FW-1/VPN-1 4.1 SP6 (the last before NG). When they try to connect to an FTP server that is located behind a Cisco PIX firewall, they are not able to transfer data: the connection is established, the authentication to follow, but at the stage of the 'LIST' the connection 'freeze' and the user must close the FTP client.

  Users are facing this problem ONLY in Active mode: passive mode works very well. Turn passive mode FTP client isn't acceptable workaround for most of my clients.

  The problem seems to be related only to the firewall Cisco PIX and active FTP.

  Please, what is someone encountered the same problem?

  Could someone give me any help?

  Thank you in advance.

  Yes it is a (global) problem, even with the last checkpoint firewalls. What happens with Active FTP, it's that each command (get, list, etc.) causes another log on the client (source port) to the server on port 21. If you run netstat from the customer you can check this for yourself.

  What normally happens, with HTTP, FTP, telnet, which have are, it's that the client makes a connection to port 21, 23 etc then returns with a port source such as 1936, 1980, 3000, etc..

  Connect problem with statefull firewall is they do not allow multiple sessions control port number on a destination, as well as a source port can be bound to a destination port, in this case, 21 for FTP. I Don t see it changed, an extreme security risk any time soon, since it s, someone else might be hopping session and block this type of traffic, it's what the stateful firewall are all about and FTP servers are problably the machines more pirated on the planet.

  You´ve mentioned the workaround solution, unfortunately that s the only way, change your passive customers, I think that Unix/Linux customers have a problem with this, change your FTP server can also help, there are multiple servers that can be configured to disable Active FTP, I wouldn know exactly, I only network & firewall... maybe someone else can move on this...

• Recording connection failure attempts

  Someone at - he found a way to get information about connection attempts that have failed where people enter the wrong username/password name? We use the secure gateway and I enabled database. I looked through the database but couldn't find anything by recording connection attempts that failed.

  Hello

  Unfortunately, vWorkspace do not keep track of connection failures, you need a product that collects this information from the event log and stores them for you to review later as Administrator Active or change auditor for Active Directory.

• session active ftp for bluetooth problem

  Hello

  I recently bought a Moto X 1 st Gen and so far everything has been great, but I noticed recently that I can't receive files via bluetooth. I can connect and pair my device and I can send files to my computer but I can't receive files. Whenever I try to do, it appears a message in the notification bar that says "Active FTP Session for bluetooth" or something like that, I can't open the message as it appears and disappears very quickly.

  Someone knows how to fix this?

  I do not use BT for file transfer, but it could be that receive files on your phone is blocked by default.

  After coupling with the computer, try to go to BT settings on your phone and computer. It should list the functions of BT supported. Under file transfer, see if there are menu options to activate the reception of files.

• ERROR: Connection failure: unknown username or bad password

  Whenever I want too run a .exe field or a program that requires administrative permissions, I type my password using the account control user, but instead of just let me through it come up with this error:

  Connection failure: unknown username or bad password.

  I searched for fixes, but have not found one that works.

  This was a very big problem I am a player computer and all the games I have, have the administrative sign (shield) and or are .exe files.

  This has happened for about 3 or 4 months now... It really gets me upset. Since there is no way to shut off User Account Control (UAC) without opening UAC itself...

  I'm running on a:

• PAT/NAT and VPN through a PIX

  "PPTP through the PIX with Port address translation (PAT) does not work because there is no concept of ports in GRE"-this is an excerpt from a config PIX version 6.2 and below.

  1. how this problem has been fixed in 6.3? GRE is encapsulated in udp or tcp to use ports to follow the connection?

  2. is it "fixup protocol esp-ike" use the same technology - the source port created by the IKE protocol? -ISAKMP cannot be enabled when you use this command

  3. What is "isakmp nat-traversal? How is this different from fixup protocol esp-ike"

  Thank you

  RJ

  1. when the PIX sees outgoing PPTP (TCP 1723 port) packets it now opens holes for them to return, as well as opening a hole for the GRE packets, it has never done this before. The PPTP TCP packets can be PAT would be fine because they are TCP packets. GRE packets, I believe, are followed by the id field only tunnel in the package.

  2. we use the source port of the ISAKMP packet for ESP packets as well. The current limitation is that if you have this option, you cannot use the PIX to close the IPSec sessions, so you can not turn on ISAKMP any interface. You can also have only a single IPSec client internal to use this feature.

  3 NAT - T is a new standard for IPSec to work through a NAT device peers, because they detect changes of address during the negotiation of tunnel and automatically encapsulate packets in UDP 4500. This market allows the PIX and the other device (if it supports it) to automatically detect a NAT/PAT device between them. This differs from the "esp - ike correction '' that the PIX ends not in fact the IPSec tunnel with esp - ike, but it is the endpoint in nat - t.

• Connection failure: unknown username or bad password

  I use Thunderbird without problem for businesses for nearly eight years. I currently run at the top of a tower with Windows 7 Pro. There is only a single account/e-mail address on Thunderbird.

  This morning when I went to check my e-mail I have my password is requested, then received the error 'sending of password did not. Mail server exchange.company.com replied: connection failure: unknown username or bad password. "I retried the password, restart Thunderbird and tried again, but still not received the same error. I sent an email from Thunderbird test which was very good. I am also able to connect to the server via web browser and I am able to send and receive emails on my mobile device.

  I erased all the saved passwords of Thunderbird and I checked account settings, but I am still unable to download any email Thunderbird.

  Apart from the deletion of the account, I don't really know what to do here. Any help would be appreciated! Thank you.

  The problem has been resolved. Apparently the POP stack had to be reset by the side of the Exchange.

  I hope this helps someone in the future...

• Qosmio F30-117: Impossible to establish FTP connections

  I have a Qosmio F30-117, windows XP, Norton Internet security.
  When I try to FTP to my site I get FTP connection failed.

  I tried it on a friends computer and the connection has been established the first time.
  When I joined my laptop to its broadband - no FTp connection. This eliminates at least my router.

  I tried to disbale parts of Norton Internet Security, without success.

  Help?

  Hello

  so if I were you I would completely disable the Norton software and make sure that the Windows Firewall is to leave you hollow. If not, you should check if your friend has put in place properly. If you want to test that your machine is able to connect via FTP, then go to www.kernel.org and enter an ftp address.

  Open your favorite FTP client, and then try to connect. If the connection fails really then double check all the settings and try again. I think that the problem is so low that everybody he oversees everything. ;)

• Win 7 driver - data FTP connection error

  I tried to download Windows 7 (32 bit) HP Deskjet and Officejet full feature software and drivers from the support link for my HP PSC 1402 for the past three days BUT get a "data connection error". Tried to do it from another PC and ISP and still the same problem... Anyone know of similar problems with the FTP server?

  Due to the huge size of the driver that is nearly 370 MB and a lot of people trying to download it could have caused the problem.

  Please try to download it from this link:

• ISE max connection failures

  In ISE, is - anyone know if the tally for the failures of maximum connection for accounts invited (found under settings > comments > political portal page) is one per session or cumulative setting during the lifetime of the account? The County never resets and is there a way to display the current number of connections that have failed?

  Our use case, is that we have guest accounts that distributed to multiple hosts (for example for a hosted conference or special event). We had a couple of this type of accounts get suspended because of hitting max connection failures. We have increased the adjustment, but I would like to understand the parameters more has some of the guest accounts must apply to a significant period of time.

  This is per session, when logged in successfully, the counter is reset.

• There is more than one active network connection on your computer

  I have two ISP with 2 different IP addresses of course. With one I connect via cable, the other is wireless. Until a couple of days, I'd keep the Wi - Fi turned off on the front of the case, to allow the laptop to connect only to the cable connection.
  Some sites were not loading, indicating problems with DNS resolution. I checked for possible reasons online. I tried to connect to these sites using a webproxy and it worked, so I thought I would try the wireless connection. I turned on and sites would be load normally. However, when I checked my ISP number this shows that the active connection cable one.
  I hesitated to leave the switch turned on, but in order to leave these sites load, I thought I had no other choice. Needless to say that I am not notified at all or with the networks or computers.
  Everything seemed to work fine until the wireless connection has started having problems anyway, it stopped working (ISP issues), so stopped at new loading sites. I tried troubleshooting it and he said: "it has more than one active network connection on your computer" and suggested I would disconnect them. Naturally, I unplugged the wireless connection. Problems: I can not load the sites that seem to need to have wireless to turn on. Note that it does not need it to be active, only to have this switch.
  Please let me know if there is anything I can do to correct this inability to connect to the servers of some sites without the need to have that switch on. If there is no explanation for this behavior, which does not make sense. Again, I know nothing about networks or computers, forgive my ignorance!
  I use Windows 7 Home Premium x 64, my laptop is a Vaio. This happens on all my browsers and sites that have stopped loading were load normally when I 1st turned on the laptop the same day. To later that day there some sites stopped to load, which made me think it was a matter of site. Then I realized that it was not connect to twitter, which was not down, so I realized it was my problem.

  It looks at when you use the wired connection THAT DNS has failed.

  In order to clarify the names of web sites means absolutely nothing to a computer in itself, www.google.com is completely useless. All comms on a network revolves around the IP addresses and the DNS service is a process by which the dedicated servers which addresses are known can tell your PC what is the address of a Web site. For some reason any on the wired connection your PC isn't getting the address to soundcloud.com.

  In family situations more of a PC it gets the IP of the router settings, of course I don't know if this is true in your case. If you open a command prompt and run ipconfig/all, paste the result here and we can check. This would include which server DNS to use that, as I said is normally the router. There are actually millions of internet addresses, and your router could not store them to remedy this it forwards a request for an address of DNS servers listed in its own configuration of IP internet side.

  If you can connect to the router and look its DSL or WAN configuration, you should find at least one or two DNS servers. Take note of them. If you can't connect to the router then look at the website from your ISP for their parameters.

  On your computer, go to the network control and Internet\Network connections, right-click on your wired card, and select Properties. Double-click Internet version 4 Protocol. In normal use get it 2... buttons should be selected, are they?

  If you change only the down one to use the following DNS server address and enter the fields, addresses that you got the router. Click OK twice, but leave the window network connections open as you need.

  Now, try to get your site into a problem. If you can then the problem is with your router. Instead of asking the router address you have bypassed this stage and went on the server, your router is configured to use.

  If you are still unable to the site then the problem is further down and your router may be OK. Then go back to where you set the addresses DNS and replace those that you got the router and turnkey 8.8.8.8 primary DNS server address and 8.8.4.4 in another address, OK once again two times and then try again the site. These 2 addresses are own Google public DNS servers and should work.

  If the ISP provided the router they should replace it. Explain what is the problem and the results of these tests, although I have no doubt that they insist on their own checks before accepting.
