Re: implementing idle-time networking

Hi, i believe there are two things here that you need to consider before you can see any queue build up in ipq: 1. you should generate packets (way) faster than the card is able to handle them; 2. the network card itself might be able to queue multiple packets in the "transmit ring";

traceroute using tcp to a port?

2000-09-19 Thread Leif Neland
If I understand correctly, traceroute works by sending pings with ttl=1, ttl=2,ttl=3 etc and records the names of the routers where the ttl reaches zero. However, an increasing number of sites believes in security by obscurity, and blocks for pings. Would the same technique work for making a

Serial port locks up 4.1

I had some PPPoE issues so I did a cvsup of FreeBSD 3.4 to help fix them. An unfortunate consequence of this is that pty's seem to be broken now with respect to certain TERMIO operations, which breaks my VPN system completely (thus leaving the client in question with a partly broken WAN).

Of course it works, and very well. You should try hping (http://www.kyuzz.org/antirez/hping/) which is a _very cool_ tool developped by Antirez. With it you could do (among many things) traceroute over tcp. Ah, you mean just like FreeBSD's "traceroute -P tcp" does? Steinar Haug, Nethelp

From The Design and Implementation of the 4.4BSD Operating System, the write(2) system call must go through vn_write(), ffs_write(), ffs_balloc(), cluster(), bio() and finally dev() which performs the actual disk write. Considering all this block-oriented overhead, how can dd(1) which calls

That is only if the write is to a file within a partition mounted as an FFS file system. vn_write() contains the VOP_WRITE switch, which will switch to the write implementation based on the vnode type. VOP_WRITE calls through the function hanging off the vnode in the vnode op vector at the
