I've got an old Juniper SSG5 running ScreenOS 5.4.0r6.0. Once a day, more or less, it'll start randomly dropping packets at a rate of ~5-10%. We currently solve this issue by simply rebooting the unit, after which it resumes working in perfect condition.
As this error has started appearing randomly…

As we've been having some problems with sporadic packet loss, I've been preparing a replacement router (also an SSG5) for our current Juniper SSG5. I've setup the new SSG5 identically to the old one.
We have a /29 IP range with a single IP setup as a MIP map to a server and two others being used…

I'm unable to get a brand new Juniper SSG-5 with latest 6.3.0r05 firmware routing to the internet from a subinterface I created on bgroup0 setup as vlan2 (bgroup0.1 on "wifi" zone). When connected on the default vlan it gets on the internet just fine.
When I switch to vlan2 I'm unable to get to the…

Is there a better way of appending a set to another set than iterating through each element ?
i have :
set<string> foo ;
set<string> bar ;
.....
for (set<string>::const_iterator p = foo.begin( );p != foo.end( ); ++p)
bar.insert(*p);
Is there a more efficient way to…

I have code for circle-circle intersection. But I need to expand it to 3-D.
How do I calculate:
Radius and center of the intersection circle of two spheres
Points of the intersection of a sphere and a circle?
Given two spheres (sc0,sr0) and (sc1,sr1), I need to calculate a circle of intersection…

Question is simple:
I have two List
List<String> columnsOld = DBUtils.GetColumns(db, TableName);
List<String> columnsNew = DBUtils.GetColumns(db, TableName);
And I need to get the intersection of these. Is there a quick way to achieve this?

hi!
given a 3D grid, a 3d point as sphere center and a radius, i'd like to quickly calculate all cells contained or intersected by the sphere.
Currently i take the the (gridaligned) boundingbox of the sphere and calculate the two cells for the min anx max point of this boundingbox. then, for each…

I had previously asked this for 3D but now I changed my strategy and would like to do the intersection in 2D.
The Rectangle is axis aligned and will always be in a fixed position, and has a constant shape and size, basically I want to clip the red areas of the triangles that extend outside the bounds…
