I have a possible sshd bug which causes inability to login via pty open failure. I'm not very good reading rpm spec files, is there a way to figure out if the current centos 4.4 sshd rpm configures with HAVE_DEV_PTMX true or false?
Evolution
NetDude: such things would likely not be defined in the spec, but in the source itself.
NetDude
Evolution: it's part of the configure script
Evolution
then look at the %configure line.
NetDude
my testing seems to indicate that it incorrectly thinks there is no /dev/ptmx/
I need to verify though because I'm probably making a mistake
the configure output I got says falsely that centos 4.4 does not have /dev/ptmx
but I hand patched it and rand configure as close as I could guess from teh spec
Evolution
NetDude: what's to guess?
the %configure line of the spec shows you what's done.
NetDude
it has some it has some #if definitions
that's percent sign if
my client is changing it to #if
like I don't know if it has kerberos or not
if it does have kerberos I dont know what the krb5_prefix is
well that was fun
Bazy
great... idiots
NetDude
dont those have to have login passwords?
         

Teada
omg
Evolution
I hate idiots.
Teada
me 2 :)
Bazy
same here...
NetDude
I just hate people entertained by causing pain to other people, idiot or not
Tead
:)
Lazydog
wow looks like i just missed the storm. :)
NetDude
anyway I'm trying to debug why my centos 4.4 sshd fails to allow more than 3 logins with "error: openpty: No such file or directory" and "error: session_pty_req: session 0 alloc failed"
it appears that some ptmx/pty bug is present
at least in x86_64
Evolution
NetDude: you mean more than three login attempts? or 3 logins period?
NetDude
3 total pty's on the system
total
Evolution
because that sounds like something possibly in your app.
NetDude
but
Tead
if i asked how to change my host name in centos, am i an idiot 2? :)
NetDude
it changes
my app?
ssh from a remote machine is the app
on fedora core
I can set the shell to ksh, bash, or tcsh, it always fails randomly around 3 logins
Evolution
NetDude: then something is horked on your end. I've got nearly 2 dozen open ssh sessions right now.
NetDude
but the error is on the server
Evolution: I have had that many at times
Evolution
or you're getting ssh brute forced.
NetDude
Evolution: are you using x86_64?
Evolution: nope I can look at /dev/pty/ and it really is only a few
Evolution
NetDude: currently no. but we do at work (which has upwards of 50 connections)
NetDude
and I can look at net traffic I'm not getting attacked
the code giving the error indicates that sshd is not understanding that centos really has /dev/ptmx
when in fact it does
         

Evolution
then file a bug, but it sounds as if it's something on your end.
Bazy
Evolution take a look at http://denyhosts.sourceforge.net , it's in fedora's core 6 base repo... it cool to use for all those idiots that try to brute force you
NetDude
Evolution: it is something on the server en dyes
Evolution
NetDude: yes. but specific to your machine.
NetDude
no it's a default install
Evolution
NetDude: are you using plesk, cpanel, or ispconfig?
NetDude
yum updated
no
none of that
it's just plain vanilla centos 4.4 server
gevik
hello, How do i rebuild the postgresql rpm to the newest version of postgresql 8.2, it is not in centosplus or contrib
NetDude
x86_64
Evolution
gevik: you don't. you get them from postgresql.
gevik: and if you do this, and they break, you'll have to contact them for support
NetDude
I guess I'll add a bug report to centos then since openssh.org will want me to use non-patched versions
z00dax
he wasent running centos was he ? that guy with the sshd problem
Evolution
z00dax: yeah. he says he was, for the server.
coming from fc6 client.
z00dax
not sure which one, but either smeserver or rocksclusters has this problem with everyone
Evolution
we'll find out in a minute when he files the bug.
z00dax
iirc, its something to do with glibc and perms on /dev/pty

oops
sorry
kayhan
hi all looking out how to use zoom x5 model 5554 usb adsl modem by usb port
couldn't find it anywhere
do i have to reconf. kernel?
z00dax
kayhan: if you send it to me, i'll take a look atit
kayhan
thanx
z00dax : the model is ZOOM Adsl x5 model 5554
z00dax
excellent
kayhan
do i have to recompile kernel for that?
z00dax
i dont know
you should first call the people yo bought that from, then call the people who make it
after youve done your research on google and forums etc
there is a good chance that someone else also has the same modem and is using it on linux
kayhan
I digged up all forums and googled al way
hope so
I am using it already but not via usb
therefore I am looking out for the USB driver ?
so I can free my cable up for the notebook
ok another thing , can CVS service be added to services that are controlled by gui
I mean , is there a cvs-server package for Centos that properly installs cvs as a service and adds itself to the services list?
good night all
jayeola

Has anyone had luck with USB Video Capture devices?
sargeantd
I have w/Fedora Core 5 and a Logitech Quickcam Messenger.
Haven't tried on CentOS yet.
RadSurfer
Qcam usb?
where are the drivers for that?
sargeantd
Let me go look. The apps I'm using successfully are: camstream and camE...
Hrm. I haven't used it in a few months. I'm struggling to remeber where to look.

RadSurfer

sargeantd
RadSurfer: I put it up on the pastebin: http://rafb.net/p/F8NrNM25.html
