I can't seem to replicate this at all with any of my available FTP clients or browser-based FTP clients. It works for me from both Mac OS X clients as well as a CentOS 5.4 based Linux system.

Is there an FTP client / OS combo that seems in particular not to work?

Hi Chris,

I'm also seeing problems with the FTP site, but using Mirror rather
than Transmit, it looks like the server does not like options being
specified to the LIST command:

Scanning remote directory /pub/EMBOSS
--->  CWD /pub/EMBOSS
250 Directory successfully changed.
--->  TYPE A
200 Switching to ASCII mode.
--->  PORT 172,21,22,1,171,245
200 PORT command successful. Consider using PASV.
--->  PASV
227 Entering Passive Mode (208,94,50,58,104,178)
--->  LIST -lat
timed out
Cannot get remote directory listing because: timed out
Cannot get remote directory details (/pub/EMBOSS)
disconnecting from emboss.open-bio.org

Trying it with a command line client I get the response to hang if I
try using any options to ls or dir, without options they are fine.

All the best,

Hamish

Hi Chris,

Did you have a chance to look at this? Just tried again, and Transmit still
won't let me access the emboss ftp site.

Thanks,

- Koen.

In the last few months the open-bio.org servers switched datacenters, IP
addresses and firewall/IDS appliances. Lots of juicy things to look at and
debug.

Koen - if you have a chance can you send me the IP address that you are
using to connect from? I might be able to find some relevant log entries
with that info.

-Chris

Just for the record, it used to work with Transmit, this is only from

Might be an issue with the Juniper Netscreen firewall/IDS security

that sits upstream of the EMBOSS FTP server. I'll take a look at the
security logs and alerts.

Hi,

For a while now I am unable to access the emboss ftp site using the OS
X
client Transmit. Loggin in works fine, but it chokes on the LIST
command. I have no problems accessing it from the command line. I have
added the output from Transmit below. I don't know if this is a
Transmit
or emboss issue, but just wanted to let you know.

Thanks,

- Koen.
