Question on vsFTPd. I just switched to it from ProFTPd. With ProFTPd clients on the LAN that connected to the ProFTPd server on the LAN had slow logins with their FTP client until in the ProPFTd config file I uncommented these two lines:
#UseReverseDNS off
#IdentLookups off
Now that I"m using vsFPTd, I was wondering if there were similar settings since I see logging into the vsFTPd server is slow (20 second delay).
Running RHEL 5.5 x64 with the latest updates. Running Oracle 11gR2. Server has 8gb ram 2xcpu 2.4 xeon.Only running one fresh instance of Oracle, no applications are even pointed at the DB.Two Issues...
1. Logins via SSH to server are extremely slow, about 30 seconds after typing password
2. Once I am logged in, launching sqlplus is very slow. After typing password, sqlplus hangs for 15 or so seconds.
Even when I am actually at the console, login of course is instantaneous.. but sqlplus still has the same issue. CPU is at 0% no swap is being used. Shouldn't be a network issue, on the same network.
there are 2 spots where I see a range from instantaneous to multi-second delays.Between issuing the ssh command and getting a login prompt and between entering the passphrase and having the shell load.Now, specifically I'm looking at ssh details only here. Obviously network latency, speed of the hardware and OSes involved, complex login scripts, etc can cause delays. For context I ssh to a vast multitude of linux distributions and some Solaris hosts using mostly Ubuntu, CentOS, and MacOS X as my client systems. Almost all of the time, the ssh server configuration is unchanged from the OS's default settings.
What ssh server configurations should I be interested in? Are there OS/kernel parameters that can be tuned? Login shell tricks? Etc?
Any clue? I'm using the same key for root login and it works fine (also works fine for SFTP but i hate using that cause its extremely slow)

View 4 Replies View RelatedWe have a public server and it can be accessed from any where through ssh.
My question is my server should not allow anyone directly to login as root user. First he should login as normal user then he should switch to root user.
I also have another questions is there any specific linux command is there to end other users ssh session without rebooting the server.
I ran into a user today that indicated that their company only allows them to log in through a terminal session once (no multiple logins). On second try their login window terminates. They are using putty.Is this being accomplished through PAM or sshd ( or some other method)?
View 1 Replies View RelatedI have a samba server that I had setup using the default smbpasswd backend, and it worked fine. So long as I remembered to use smbpasswd/passwd to setup a user with a username and password matching the account name of a Windows 7 user, then that windows 7 user would be able to navigate the shares with their permissions correctly.I have switched over to using ldap, and: the console/ssh of the machine can correctly use any of the ldap logins getent passwd/group both show the complete listing my Windows 7 machines can all ping the samba server by its netbios name my Windows 7 machines all prompt for authentication if I type \MACHINENAME into explorerHowever, all attempts to access the shares now continually ask for you to enter your username/password, and then fails anyway.No errors appear to be generated on the server (unless I'm missing a log somewhere). Having hunted around on the web, I'm wondering if it has to do with generation of machine accounts (since it tries to access from MACHINENAMEUSER). Without ldap setup, I didn't need to worry about the machine name, but I'm thinking that maybe smbpasswd took care of this somehow.I use the smbldap-useradd tool to setup a user account, which appears to correctly setup the user in ldap, such as:
Code:
dn: uid=sharer,ou=Users,dc=intbus,dc=net
objectClass: top

my /var/log/secure file is not getting updated with ssh logins from yesterday.Even the login from my own ip is not updated.

Most applications used on the LAN are windows based, with a growing number of python apps. A friend suggested a Primary Domain Controller would be a better way to manage logins, resources etc. I don't wont to use a Windows based PDC, what would you suggest as a linux based PDC? I have heard about TURNKEY PDC, but it uses Samba 3 and apparently doesn't handle Active Directory in Windows.

vsftpd ver: vsftpd-2.0.5-12.el5_3.1
I installed vsftpd server in one of my servers using "yum install vsftpd" command. NFS server is running in the other server and mounted as "/data" in this FTP server. root in FTP server has also root authority in NFS server. All the files and sub-folders under "/data" in FTP server have 755 or 766 mode. Even I modified vsftpd setting to allow root login.
When I login as root to FTP server with FileZilla client, I can see all the file list in root home directory and move to /data directory. I can download any file in a local HDD but I can not download any file in /data directory.
pls tell me complete configuration of vsftpd server on redhat 5

I just installed Ubuntu server and wish to run an apache web server from it. I have that setup, with each user having their individual folder. (E.G) apache root /var/www/ LazerPhreaks folder is /var/www/LazerPhreak/ so their website would be www.mysite.com/LazerPhreak/) I wish to setup vsftp to let each user access their individual folder and upload website files via ftp. How should I go about this?

Does someone know of a solid article on what files to back up to restore a vsftpd server onto another server?
Right now i'm backing up the ftp directory structure with all the files in it, but no configs, users, etc
I've setup vsftpd for my FTP on my server, I edited the vsftpd.conf to allow me user to gain access to their home directory, It doesn't seem to let me in, I'm getting the error

this is set at yes
I've set it to NO and I get

I don't quiet under whats going on, I followed this tutorial [URL]

which is the best vsftpd or Proftpd or Pureftpd ?
which is high secure and reliable ?
Pureftpd or Proftpd can install on Centos ?
I am trying to use cron and FTP to backup files regularly from my main server to a backup server. The backup server was a "bare bones" setup with no control panel or even FTP. It is running CentOS 5.3.
I installed VSFTPD which appears to be running OK and I can connect via FTP from my other server, but when I try to run my backup script (it uses mput) I get a "553 Could not create file" error.
Some relevant info:
The user I have created for this is "ftz" with home directory /home/ftz/
Running ls -l shows: drwxrwxrwx 3 ftz ftz 4096 Dec 18 07:46 ftz
so permissions and directory ownership don't seem to be the problem.
vsftpd.conf was left in default form:
Code:
# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.

View 26 Replies View RelatedMy ftp server runs vsftp. The ftp passive ports stopped working while iptables is running, so users can't ls their dirs. I know that you need to load the modules of ip_conntrack and ip_conntrack_ftp, the problem is when I modprobe ip_conntrack I get the error: FATAL: Module ip_conntract_ftp not found. No that is not a typo. ip_conntract_ftp? Am I missing something?
