freebsd packages for onefs

[Dan Pritts]

I wanted "tcpslice" [1] today, so i could trim down a packet capture before sending it to support.  Obviously I could have run it from an NFS client but at 1Gb that would have taken a while.   So, i wanted to run locally on the cluster.  
 
Wikipedia told me that onefs 7 is based on freebsd 7.4. 

I found the binary "packages" distribution for FreeBSD 7.4 here: 

http://ftp-archive.freebsd.org/pub/FreeBSD-Archive/ports/amd64/packages-7.4-release/

a download and "pkg_add" command later and i was in business.

These binaries are old, from the release of 7.4 in 2011, so i would strongly recommend against doing anything with any untrusted input. 

YMMV, unsupported, if it breaks you get to keep both pieces.

[1] If you are trying to use tcpslice, note that time 1 means unix timestamp 1, i.e., 1 second into 1970.  time +1 means 1 second after the start of the tcpdump file.  Never knew that the tcpdump format stored actual time stamps.

The kernel and user space C libraries in OneFS are not identical to the ones in FreeBSD 7.4 - that is they have many modifications.  The kernel itself is modified extensively.  The userland libraries are mostly standard but you may have cherry picks that change the function interfaces here and there.  Some user space functionality is also heavily modified (protocol stacks, etc) - but this is usually more obvious from the binary names and in some cases, the package names (pkg_info).

Thus, you have to be a little careful with 3rd party binaries because there may be some linking issues.  In certain cases you could link fine but have segmentation faults or worse if the interface hasn't changed but the behavior has.  So my advice would be to definitely explore your options, but be watchful.  

Good info Dan, but just wanted to put out a disclaimer in case others are thinking of trying the same.

What you REALLY REALLY want to avoid in the first place is that 

the shit hits the /bin ...

i.e. overwriting any OneFS installed stuff.

Note that pkd_add isi supposed to install dependencies, too.

In the outrageously surreal case where one feels entitled to bring 

foreign binaries to OneFS, better extract them elsewhere and then 

bring them to /opt/mystuff or similar -- do not even dream 

about /usr/local. And destroy after use immediately...

Clearly. 

One who works on this level had best know what they are doing. 

In the outrageously surreal case where one feels entitled to bring 

foreign binaries to OneFS,

In the outrageously surreal case where one feels entitled to install software
on the computer(s) that he has paid tens of thousands of dollars for...

I.e., I am "entitled" to do whatever I want with the thing.

At the same time, I have a support contract where EMC has laid out
conditions.  EMC is entitled to decline to support me if I break those
conditions.  Which I hope is your point.

I should add, in case it isn't clear, that the freebsd packages tree includes just about any unix software you can think of.

Therein lies the rub.
