[redhat-list] sftp error question

Hi Mark,

(And, presumably, restarting sshd (service sshd restart).

(This would have to do with the apache configuration (httpd); that's in /etc/httpd/conf and /etc/httpd/conf.d Sounds to me as though the virtual hosts are messed up, or possibly that you have secondary IPs, for which you need to look at /etc/sysconfig/network-scripts.)

(What I did at work, several years ago, was to talk to the system owners, and set up a regular monthly maintenance window, when I could do full updates - bug and security fixes - and reboot as needed. And they make sure their users know of the window.)

(Third, if this is a server, and *esp* if it's a production machine, I would recommend turning off yum-updatesd (that's the auto-updated; it doesn't exist in 6.x) - you should consider the updates, and coordinate if there's something that your users might see, like NFS or apache, etc.)

> Thank you - I will turn that off as it is a production server. What did you mean by: " you should consider the updates, and coordinate if there's something that your users might see, like NFS or apache, etc"? I assume you meant, being careful what updates I do and when I do them, but I wasn't sure.

Thank you for responding Mark!

Hi, Constance,

You've probably got several things going on.

First, finish the full updates, really. 5.7 is several years old - it's now on 5.9, for the 5.x branch (the 6.x is up to 6.4 as of several months ago) and if you type lsb_release -a, that's what you should see. Having it partly updated is asking for trouble, esp. if interrelated packages are not all installed, such as an application like apache, but libraries it needs aren't updated.

Second, when you do a reboot, it *will* have major issues, unless you finish that update, for the reason above.

Third, if this is a server, and *esp* if it's a production machine, I would recommend turning off yum-updatesd (that's the auto-updated; it doesn't exist in 6.x) - you should consider the updates, and coordinate if there's something that your users might see, like NFS or apache, etc.

This would have to do with the apache configuration (httpd); that's in /etc/httpd/conf and /etc/httpd/conf.d Sounds to me as though the virtual hosts are messed up, or possibly that you have secondary IPs, for which you need to look at /etc/sysconfig/network-scripts.

*Do* run yum update regularly. RH should be emailing you about updates; anything labelled "critical" (like firefox) should be done that day; important, if you read what it fixes and find that it affects you, in the next couple of days. What I did at work, several years ago, was to talk to the system owners, and set up a regular monthly maintenance window, when I could do full updates - bug and security fixes - and reboot as needed. And they make sure their users know of the window.
