I am experiencing intermittent network failures on rsync 3.0.7 built using cygwin for Windows-XP (SP2). I am using GCC v4.4.2 and the latext version of cygwin. The rsync error long indicates things like: rsync: writefd_unbuffered failed to write 4092 bytes to socket [generator]: Connection reset by peer (104)rsync: read error: Connection reset by peer (104) rsync error: error in rsync

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.

...r, the keepalive value ought to be set in any case. My suggestions: 1. Move keepalive setsockopt out of packet_set_interactive, as it's not related to interactive vs non-interactive. Instead, make the keepalive setsockopt call in: ssh -- in sshconnect.c, after the setsockopt for SO_LINGER, right before call to packet_set_connection. sshd -- in sshd.c, after the setsockopt for SO_LINGER. 2. Secondarily, for ssh and sshd, ensure packet_set_interactive is called for ssh2 also if appropriate. ----------------------- As an aside (as information for anyone else with the...

...connection? Thanks, Jerry ---------------------------- This text has been taken from the original FAQ. 2.1 - How can I tell when a socket is closed on the other end? From Andrew Gierth ( andrew at erlenstar.demon.co.uk): AFAIK: If the peer calls close() or exits, without having messed with SO_LINGER, then our calls to read() should return 0. It is less clear what happens to write() calls in this case; I would expect EPIPE, not on the next call, but the one after. If the peer reboots, or sets l_onoff = 1, l_linger = 0 and then closes, then we should get ECONNRESET (eventually) from read(),...

I will try to explain this as best I can. I have two computers; one a Supermicro X10SAE running CentOS 6, the other a very old DOS box.[*] The DOS box runs a CCD camera, sending images via Ethernet to the X10SAE. Thus, the X10SAE runs a Python server on port 5700 (a socket which binds to 5700 and listens, and then accepts a connection from the DOS box; nothing fancy).[**] The DOS box connects to

Folks, I've noticed poor performance using sftp. If anyone has any advice on how to improve performance, I'd like to hear it. Test simply involved transferring a single 143MB MP3 file using defaults for all the program configs. The opensshd 3.0.2p1 server is used in all tests. Software: openssh suite 3.0.2p1 psftp (putty sftp client) latest dev snapshot pscp (putty scp client) latest

...uld reveal this. But what happens if the server writes to the socket, and the client never reads? (We do, as it happens, have access to the client software, so the protocol can be fixed eventually. But I'm still curious as to the answer.) 3) Several people suggested using SO_REUSEADDR and/or an SO_LINGER of zero to drop the socket out of TIME_WAIT, but does the socket enter TIME_WAIT as soon as the client crashes? I didn't think so, but I may be wrong. 4) Several people suggested SO_KEEPALIVE, but those occur only after hours unless you change kernel parameters via procfs and/or sysctl, and whe...

SIG record support is found in multiple versions of BIND, including 4.9.5 through 8.x. Vulnerability #3: the "so_linger bug" By intentionally violating the expected protocols for closing a TCP session, remote intruders can cause named to pause for periods up to 120 seconds. Vulnerability #4: the "fdmax bug" Remote intruders can consume more file descriptors than BIND can properly...

On this server I have defined two queues which are csqlis and HPfinley. csqlis seems to work correctly and displays ready. HPfinley always reads Paused on win2k and NT40 clients.
