search for: setsockopt

I would like to remove setsockopt(SO_LINGER), as there does not seem to be a reason for its use. If you know of specific reasons we should keep any of these let me know, or run this patch in local test trees where possible. This is against OpenBSD, but should apply to portable with some fuzz.

...604T wireless router. ssh client was hanging at: debug1: Entering interactive session. Telnet was having a similar problem to port 22, however a simple client.c I compiled was not. My java ssh client was also working. After some investigation, I noticed that the hang was after the system call: setsockopt(3, SOL_IP, IP_TOS, [16], 4) = 0 I noticed also that telnet was hanging the same way. I commented all the setsockopt() calls out of the ssh client code (because I was in a hurry) and now it works. Anyway, I figured I should document the problem somewhere. -Ken _________________________________...

I know i'm new to the list but i'd like to propose something for tincd daemon. I'd like to mark all sockets established by a tincd process with a mark passed as an argument in the command line. What could be the purpose of this new option? The goal of this option is to be able to have several tincd process running at the same time using the same port but using different ip. In

Hi! There are configuration knobs (TCPKeepAlive) to enable/disable the use of TCP keepalives both in the ssh client and server. Unfortunately some UNIX systems default to SO_KEEPALIVE=on and some to =off. This may even be settable on a per host basis (OpenBSD default net.inet.tcp.always_keepalive=1 ???). For the TCPKeepAlive configuration knob I would like to propose changes along the lines

I have built samba 3.0.4 on Solaris 9 and it appeared to compile and build OK. It starts up and runs with a PDC smb.conf. It becomes the brows master for the domain and generally seems to look OK. However, when I try to join a PC into the domain I get "Invalid argument" logged by set_socket_options() in lib/util_sock.c when trying to set TCP_NODELAY and SO_KEEPALIVE. This is

So as of recent kernels, this change helps: http://git.kernel.org/?p=network/tftp/tftp-hpa.git;a=commitdiff;h=c6d2c36b1a2b1986cab7aebb72d120fa118bdfeb But there is still a flaw. Notably, if tftpd is running with AF_UNSPEC (as it will if ipv6 support is desired), myrecvfrom will fail to setsockopt to get the data back on the first pass. I'd guess the least disruptive change to get to be correct would be: diff --git a/tftpd/recvfrom.c b/tftpd/recvfrom.c index d050b80..fe233da 100644 --- a/tftpd/recvfrom.c +++ b/tftpd/recvfrom.c @@ -149,16 +149,16 @@ myrecvfrom(int s, void *buf, int len,...
