Hi!! I found your ipconfig stuff in the udev rpm in SuSE 9.1. I'm about to setup a initramfs (pretty cool - much better than initrd) to boot linux diskless clients over the net. All the tools I would need, seem to be there with ipconfig/nfsmount ... I like to use the information I get from PXE/syslinux or Etherboot writing something like:

If an ssh server receives a tun/tap tunnel request and sets up the tunnel concerned, as far as I can see there is currently no way for the server to configure the tunnel in a manner dependent upon (e.g) the key used to set up the ssh session. Whilst an id based on the key can be passed to the ssh child process, where the tunnel is dynamically allocated, its tunnel name is lost. This patch

...e = 1; int j; struct ifreq ifr = { 0 }; bzero (i, sizeof (struct iface_struct)); i->name = strdup (name); i->fd = socket (AF_INET, SOCK_DGRAM, 0); if (i->fd < 0) { syslog (LOG_ERR, "Can't open socket: %m"); exit (1); } strcpy (&ifr.ifr_name[0], name); if (setsockopt (i->fd, SOL_SOCKET, SO_BINDTODEVICE, &ifr, sizeof (ifr))) { syslog (LOG_ERR, "Can't bind to interface %s: %m", name); exit (1); } bzero (&ifr, sizeof (ifr)); strcpy (&ifr.ifr_name[0], name); if (ioctl (i->fd, S...

If an ssh server receives a successful inbound ssh connection with 'ssh -w' without a tunnel number specified (i.e. in 'any' mode), it allocates the next tunnel device available on the server. The next thing the server needs to do is to set up the tunnel device. How does the server know which tunnel device was set up by the current connection? I'd really like something

Numerous how-tos all over the Internet show how one would set up a tunnel using ssh, e.g.: ssh -f -o Tunnel=ethernet <server_ip> true I was wondering if there's a way to subsequently acquire the names of the local and remote tun/tap interfaces (e.g., using the default "-w any:any") for subsequent automatic tunnel configuration, e.g.: ip link set $TapDev up ip link set

Hi, The CBQ config file shud be some thing like this. DEVICE=eth0,10Mbit,1Mbit RATE=50Kbit WEIGHT=5Kbit Shall i hardcode the DEVICE BW as 10/100 Mbit or Shall i use any other tool like ethtool for getting this. ethtool gives Speed: 10Mbps If so, how about, if i use some other Interfaces other than eth0, like ppp0 or some other? C''d anybody can give a suggestion over this? thanks

...#39;s not clear enough and also if you don''t agree : - The case it shows the flag with iproute is because it''s using a single flag set. That was working on kernels linux <2.1.x. (2.0 etc.) Basically the mechanism was : --- strncpy(ifr.ifr_name, our_device, IFNAMSIZ); ioctl(sock, SIOCGIFFLAGS, &ifr); ifr.ifr_flags |= IFF_PROMISC; ioctl(sock, SIOCSIFFLAGS, &ifr); --- And only one could set the IFF_PROMISC, because if another process decided to set it too, then it was c...

Hi, I have used bridge-utils 0.9.6 so far in a kernel 2.4.26, uClibc and ppc environment. When I use version 1.0.3 I have the problem that I do not see the brige with the 'brctl show' command if it is not fully set up. It was working with 0.9.6. I tracked the problem down to an 'incompatibility' in bridge/uClibc/kernel. 0.9.6 uses its own if_indextoname function which uses the
