[Bacula-users] Linksys is killing socket between director and SD

[Brad P. <b_p...@ya...>]

Aaah, I've finally figured it out.  The very common Linksys WRT54G v5 route=
r IS dropping inactive sockets after exactly 10 minutes. =0A=0AI verified t=
his through a process of elimination.  Any time the Linksys router was used=
, I'd get a socket drop at 10 minutes (wireless or ethernet cable included)=
.  But when I bypassed the Linksys router and kept everything else the same=
, it all worked.=0A=0AI think that makes any Bacula job longer than 10 minu=
tes impossible using this Linksys router.  Looks like I'm out of luck.  I h=
ave updated to the newest firmware, and the Linksys config doesn't have any=
 ability to modify the timeout value.   I suppose I could buy a new router,=
 or set up a new offsite backup storage daemon.   Unless anyone else has an=
y brilliant ideas  :)=0A=0AKern, if you are reading this, what are the chan=
ces that a heartbeat could be implemented between the director and the stor=
age daemon?=0A=0ABrad Peterson=0Ab...@ya...=0A=0A  =0A----- Origi=

Subject: [Bacula-users] Director losing socket with SD=0A=0AFirst, my reque=
st:  Is there anything in Bacula I can do to keep the socket between the di=
rector and the storage daemon alive?=0A=0ANow, my explanation why I need th=
is.  As I'm trying to narrow down why my lengthy backups to an offsite stor=
age daemon don't work, I sat and watched the debug output for the director,=
 the storage daemon, and the file daemon.  About almost exactly 10 minutes =
in, the director's debug output said this:=0A=0Amsgchan.c:333 =3D=3D=3D End=
 msg_thread. use=3D2=0A=0AAfter a lot of research, it appears what's going =
on is this:=0A=0A1) The director starts the job.=0A2) A socket is opened be=
tween the director and the storage daemon.=0A3) A socket is opened between =
the file daemon and the storage daemon.=0A4) The file data transfers just f=
ine over the file daemon/storage daemon socket.  =0A5) At almost exactly 10=
 minutes in, I get the above debug message which means the socket between t=
he director and storage daemon has been closed.  netstat confirmed this.=0A=
6) The file data continues to transfer just fine to the storage daemon.=0A7=
) When the file daemon is done, it tells the director that it is finished.=
=0A8) The storage daemon tries to tell the director it received the data pe=
rfectly, but cannot, because it cannot communicate with the director anymor=
e (which makes sense, because the socket died).=0A9) *I think* the director=
 waits a bit for the the storage daemon, or it just knows it can't receive =
info from the storage daemon.  In any event, the director quickly marks the=
 job as having an error because it never heard from the storage daemon as t=
o its final result.=0A=0ASo, what can I do in Bacula to keep the socket bet=
ween the director and the storage daemon alive?=0A=0AI'v already set a hear=
tbeats of 30 seconds, but according to the manual, the heartbeats help the =
file daemon talk to the director, the file daemon talk to the storage daemo=
n, and the storage daemon talk to the file daemon.  But in my situation, I'=
m losing a socket between the director and the storage daemon, and the hear=
tbeat doesn't help out with that.=0A=0AI'm also starting to think a Linksys=
 router may be the reason why it loses the inactive socket after almost exa=
ctly 10 minutes, as other Linksys users have found this happens to them.  I=
'll be able to test this out tonight by bypassing the router completely. =
=0A=0AAnyways, in the meantime, anybody know how I can keep that socket ali=
ve?=0A=0ABrad Peterson=0Ab...@ya...=0A=0A=0A=0A=0A=0A=0A=0A =0A__=
