Hello, This is on Centos 6 and not something I think is wrong with Centos 6 but I am looking to see if anybody else has experienced this and if there is solution. So thanks up front for indulging me. Because Linux makes routing decisions before SNAT it is causing problems when trying to use FTP with two upstream providers in a load balanced setup. Other than ftp, things seem to work OK. Below

Hello, I'm trying to use http from syslinux.efi but it fails while trying to establish the connection to a FreeBSD http server. A packet capture shows: TCP healthd > http [SYN] Seq=0 Win=65535 Len=0 MSS=1460 WS=64 TSval=1094 TSecr=0 TCP http > healthd [SYN, ACK] Seq=0 Ack=1 Win=65535 Len=0 MSS=1460 WS=64 TSval=1596927428 TSecr=1094 TCP healthd > http [ACK] Seq=1 Ack=1 Win=2097152

Hi folks, I'm setting up a new dovecot email service and have a proxy server running in front of it to facilitate migrating users from my very old UW-IMAP-based mail server to the new one. I have a mysql proxy table that directs inbound IMAP and LMTP connections to the correct server, works great.

Hello, I've got an issue with RHEL6 running smbd & winbindd version 3.6.9-168.el6_5. This is authenticating against a Windows 2008R2 domain using the rid backend. If I run any command that has to look up user info I get a 35 second delay, after this initial delay it's fine until the cache time-out, then it happens again. This is making logins and most commands hang for 35 seconds

Hi, yesterday we experienced a heavy request flooding from multiple servers being a domain member against our Samba Sernet DCs. All those servers are domain members and allow login using PAM (Samba+Winbind). Running TCPDump we had like 400 Requests per 5 seconds like this: tcpdump -i eth0 dst port 389 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0,

A problem here getting winbind traffic to be encrypted using Kerberos. I have set up a test environment with a pair of servers (actually lxc containers): - samba server (ubuntu 16.04, stock samba 4.3.11) - client machine (ubuntu 16.04) joined with "net ads join" and winbind The client machine has the following in /etc/samba/smb.conf: ------- [global] #netbios name = client-ad

Hello, Stephen, thank you for input. Yes, these servers have the same firewall rules, and both of them have the same problem from time to time, most of time they are good. Actually, these servers are newly installed to be used as the Glusterfs storage server, so not much data flowing at this time. >From the sysctl output, I suppose it can't be a conntrack table overflow :

Hi?guys. There is a wierd problem with iptables recently, hopes somebody can help me. I have installed Centos 7.2.1511 on a bare metal Dell server these days, disabled firewalld and enabled iptables.services, and setup a group of very simple rules, as the following: # iptables-save # Generated by iptables-save v1.4.21 on Tue Apr 23 09:15:14 2019 *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT
