Perfect Forward Secrecy on existing installation

$

0

Hello togehter,

 

yesterday, I updated our Serv-U Installation from 15.1.5 to 15.1.6. In the changelog, I noticed, that perfect forward secrecy is implemented, but only on new installations. My question is: how can I activate this feature in our existing/updated Installation?

 

best regards,

Markus


Graceful connection log off - prevent logins

$

0

Hi All

Is there a way to gracefully disconnect and prevent logins to Serv-u MFT, without interrupting existing sessions?

Looking to patch my server and want to allow trickle log off and prevent logins.

 

Currently using HTTP/HTTPS with LDAP Authentication

 

I can see there is the Enable Domain Flag, presumably this just Kicks sessions straight out and prevents login to the domain

I can stop Serv-u, again would kick existing session off

 

The only potential I see at this stage is to disable My Authentication, wait for the user sessions to disappear then Stop serv-u

 

Interested to know how others approach taking MFT offline for maintenance

Our security scans show Serv-U 15.1.6.25 is vulnerable to CWE-693. How can I change the config so it will have the proper HTTP response headers.

Serv-U Gateway on linux slowness

$
0
0

I have installed Gateway 15.1.6 on a virtual CentOS 7.5 server and it has slowed the transfers down by about 45%. When I swapped in a Server 2016 running Gateway the speeds were fine. Anyone know why the Gateway app on Linux is so much slower?

 

All servers are in a Nutanix AHV environment with multiple 10G nics. The Centos 7.5 server was made with default settings and only has Gateway on it. Retransmitted packets seems to be part of the issue but netstat isn't showing any drops.

Desparate to solve ServU FTP freezing problem

$
0
0

We are using Serv-U FTP 15.1.3.3 to act as a gateway to an image library. Our system uses one shared account to access many tifs and jpg files. They are small in size and 99% of the time it works just fine.  We typically have about 1 transfer happening every 10 seconds or so during business hours.

 

For the past 3 weeks we have had a condition where the serve esentially freezes up for about 10 minutes. The verbose lo I turned on stops recording and then what happens is that a hundred plus users start queuine up so that when the server "wakes up" again it has so many requests at once that we hit the 100 user license limit and takes a while to catch up. These 10 minute outages are essentially blank time in the logs and we don't know where to go from here.

 

Our workload is about the same each day and the requests come from an app so it's not like the user can do different requsts. Dozens of hours have been spent to find that the ServU server is doing this or befing affected by something to do it.

 

Is this a bug in ServU or can you help me diagnose this for our company?

 

Thank you so much!

How can I change the base url for my Serv-U FTP Server? I am running Serv-U FTP server on Windows Server 2016. Creating a sub-domain just for my FTP server is not an option for me unfortunately.

 

example

https://www.mydomain.com/ftpserver

 

Thanks,

Hi All,

More a question than a discussion. Is it possible to divide the send and request files section ?

I want to sent another ( automatic ) email when I request files than when I send files.

 

Thankx for the thinking..;-)

Event ID 16002: TCP Socket Taking Longer Than Expected to Close

Hello,

 

We've been getting this error on our Serv-U Gateway server twice in the last 4 days, but never had it before.  It's running on Windows 2012 R2 and ESXi 6.5 (VM version 13), VMware tools 10305.  I have to reboot the entire server to get it to clear.  I've tried restarting the Gateway and it will stop but not start again, probably due to the port being locked.

 

So far I can't correlate this with anything else.  Has anyone else come across this?

(note that the process the error is tied to is the Serv-U Gateway.)

 

Thanks.

Has anyone been able to get Serv-U to work when the client is requiring key exchange diffie-hellman-group-exchange-sha256?  We're running Serv-U 15.1.6, but it's not working because I don't think this version supports key exchange diffie-hellman-group-exchange-sha256.  Thanks.

As the title suggests, what is the recommended way to update Serv-U on linux, do i just re-run the installer - the documentation doesn't really cover this.

FTP server denied public IP

$

0

Hi All,

 

Has anyone experienced this issue where the FTP server blocked an external public IP address and placed in the IP Access as denied? What follow after is horrific, slowly internal servers that access to the FTP server also get blocked if there is an IP address in the IP Access list.

 

The denied IP is not an admin blocking it but the ftp server blocking it. This is what I am experiencing on version: 15.1.4.6

 

 

Thanks,

Thomas

MFT LDAP Groups Question

$
0
0

If I have 2 AD Security Group, where I have Users assigned (some users are in Both Groups)

Some users in seperate groups

If I grant Access to a different Home Dir and Assign permission to different folder structure

does MFT application affectively only allow the users to view the more restrictive folder

Also does the MFT apply least restriction to those users in both groups

 

Example

I have a group that I make the Home Dir %DOMAIN-HOME% and Directory Access %DOMAIN_HOME% with RWADN-L---I

the 2nd Group Home Dir %DOMAIN-HOME%\Subfolder and Directory Access %DOMAIN_HOME%\Subfolder with RW-DN-L---I

 

Just wondering how MFT applies its rules for Home DIR and rights

Thanks

FTP Voyager and Wells Fargo SAFE-T

Good Morning,

 

We use FTP Voyager to trade files with Wells Fargo.  They are updating the connection parameters, but the lingo doesn't quite mesh with FTP Voyager.  Here are their words:

 

  • You now may test connectivity (safetransvalidate.wellsfargo.com) with the following more secure algorithms:

 

  • DH_GROUP_EXCHANGE_SHA256
  • ECDH_NISTP256

 

The descriptions under SSH Ciphers or SSH MACs do not jive with what Wells Fargo is asking for and my initial guesswork has been unsuccessful.  I'm hoping someone can point me in the right direction.

 

Thanks for your help!

Executable Event won't trigger

$

I have a simple BAT file setup so that it's triggered when a file is uploaded to an FTP account,  as an executable event.

 

It works fine going through the website interface.  It works fine connecting with an FTP Client software.  But it is not triggered if I upload a file through Windows Explorer / File Manager.

 

Why?  It's still an FTP connection,  it uses an FTP URL with embedded username and password ... it's just a different software doing it.
