Juniper vs. FTPES

If you get timeouts connecting to a FTPES server, check if ALG is enabled (usually is):
JunOS> show security alg status
ALG Status :
DNS : Enabled
FTP : Enabled
H323 : Enabled
MGCP : Enabled
MSRPC : Enabled
PPTP : Enabled
RSH : Enabled
RTSP : Enabled
SCCP : Enabled
SIP : Enabled
SQL : Enabled

Enable secure FTP and FTP-ssl protocols:
JunOS# set security alg ftp ftps-extension

Commit and enjoy FTPES!

Hardware:
- IBM BladeCenter H
- HS22V and HX5 blades with Brocade 2 port 10GbE Converged Network Adapter, no local drives

At the time of writing the Brocade 2 port 10GbE Converged Network Adapter for IBM BladeCenter (81Y1650) is supported on VMware ESXi up to version 4.1.

To install VMware on the blades, a custom VMware ESXi 4.1 ISO image with Brocade CNA drivers is required.

Exactly what I wanted to see on a production server…

RHEL 6.1 / Scientific Linux 6.1 dmesg:

TECH PREVIEW: fscache may not be fully supported.
Please review provided documentation for limitations.
FS-Cache: Loaded
FS-Cache: Netfs 'nfs' registered for caching

Excerpt from RHEL 6.1 Technical Notes, Chapter 3. Technology Previews:

FS-Cache
FS-Cache is a new feature in Red Hat Enterprise Linux 6 that enables networked file systems (e.g. NFS) to have a persistent cache of data on the client machine.

… and nothing about the limitations or how to disable fscache.

Tried to add install fscache /bin/true to /etc/modprobe.d/fscache.conf with the following dmesg result (of course, no NFS filesystems mounted):

nfs: Unknown symbol __fscache_read_or_alloc_pages
nfs: Unknown symbol __fscache_relinquish_cookie

ldd equivalent under Mac OS X

You can use the object file displaying tool – otool. The ldd equivalent otool parameter is -L:

-L print shared libraries used

Example:
$ otool -L ~/bin/wget
/Users/cbredi/bin/wget:
/usr/lib/libssl.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
/usr/lib/libcrypto.0.9.8.dylib (compatibility version 0.9.8, current version 0.9.8)
/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 125.2.1)

If you do not have the otool command, make sure Xcode is properly installed.
